  • iPhone wb dev with jqTouch

    - by sea_1987
    Hi there, I am some real trouble getting the transitions working for my iPhone site, I am trying to add the 'flip' transition using, <a class="button flip href="#about">About</a> However I get no flip transition nor do is navigate to the about anchor, here is my HTML, <!DOCTYPE html> <head> <meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0; user-scalable=0;" /> <title>Elfm Iphone</title> <script src="javascript/jquery.1.3.2.min.js" type="text/javascript" charset="utf-8"></script> <script src="javascript/jqtouch.min.js" type="text/javascript" charset="utf-8"></script> <link rel="stylesheet" href="css/jqtouch.css" type="text/css" media="screen" title="no title" charset="utf-8"> <link rel="stylesheet" href="themes/apple/theme.css" type="text/css" media="screen" title="no title" charset="utf-8"> <link rel="stylesheet" href="css/base.css" type="text/css" media="screen" title="no title" charset="utf-8"> <script type="javascript/text"> $.jQTouch({ icon:'kilo.png', statusBar:'black' }); </script> </head> <body> <div id="about"> <div class="toolbar"> <h1>About</h1> <p>Some about blurb, telling the users about the station and the site, in most cases this won't be a very extensive page, just some background information, nothing that will overface the user and not want them to carry on listening. I would probably be a good idea to push the user to the stream as well. This could be done as an internal link, something like, why not listen to our <a href="http://www.twovalleysradio.co.uk/iphone/stream.pls">live feed?</a></p> </div> </div> <div id="blog"> <div class="toolbar"> <h1>Blog</h1> </div> <p>The blog should be an easy things to implement we should just be able to use the stations RSS feed from wordpress and then style up the entries with CSS to match the look and feel of the sites. We could possibly implement the nice listing features that come with the theme available and if not we could easily build our own theme.</p> </div> <div id="home" class="current"> <div class="toolbar"> <h1>Home</h1> <a class="button flip" href="#blog">Blog</a> </div> <div id="header"> <img src="images/elfm-header.png" alt="ELfm" title="ELfm" /> </div> <div id="content"> <p>Here's a load of text about is and where it's based and why it's coll and who listen to it and a load more blurb and now I'm just adding filler for the sake of it and I know dynamic text is a pain because then we have to consider what happens if there is too much of it but we'll show a live preview on the web service of what the app would look like.</p> </div> <div id="play"> <div id="button"> <a class="play_stream" href=""> Play </a> </div> </div> </div> <div id="twitter"> <div id="tweet"> </div> </div> </body> </html> I am testing this is Chrome and Safari and also the iPhone simulator.

  • Three ways to upload/post/convert iMovie to YouTube

    - by user351686
    For Mac users, iMovie is probably a convenient tool for making, editing their own home movies so as to upload to YouTube for sharing with more people. However, uploading iMovie files to YouTube can't be always a smooth run, I did notice many people complaining about it. This article is delivered for guiding those who are haunted by the nightmare by providing three common ways to upload iMovie files to YouTube. YouTube and iMovie YouTube is the most popular video sharing website for users to upload, share and view videos. It empowers anyone with an Internet connection the ability to upload video clips and share them with friends, family and the world. Users are invited to leave comments, pick favourites, send messages to each other and watch videos sorted into subjects and channels. YouTube accepts videos uploaded in most container formats, including WMV (Windows Media Video), 3GP (Cell Phones), AVI (Windows), MOV (Mac), MP4 (iPod/PSP), FLV (Adobe Flash), MKV (H.264). These include video codecs such as MP4, MPEG and WMV. iMovie is a common video editing software application comes with every Mac for users to edit their own home movies. It imports video footage to the Mac using either the Firewire interface on most MiniDV format digital video cameras, the USB port, or by importing the files from a hard drive where users can edit the video clips, add titles, and add music. Since 1999, eight versions of iMovie have been released by Apple, each with its own functions and characteristic, and each of them deal with videos in a way more or less different. But the most common formats handled with iMovie if specialty discarded as far as to my research are MOV, DV, HDV, MPEG-4. Three ways for successful upload iMovie files to YouTube Solution one and solution two suitable for those who are 100 certainty with their iMovie files which are fully compatible with YouTube. For smooth uploading, you are required to get a YouTube account first. Solution 1: Directly upload iMovie to YouTube Step 1: Launch iMovie, select the project you want to upload in YouTube. Step 2: Go to the file menu, click Share, select Export Movie Step 3: Specify the output file name and directory and then type the video type and video size. Solution 2: Post iMovie to YouTube straightly Step 1: Launch iMovie, choose the project you want to post in YouTube Step 2: From the Share menu, choose YouTube Step 3: In the pop-up YouTube windows, specify the name of your YouTube account, the password, choose the Category and fill in the description and tags of the project. Tick Make this movie more private on the bottom of the window, if possible, to limit those who can view the project. Click Next, and then click Publish. iMovie will automatically export and upload the movie to YouTube. Step 4: Click Tell a Friend to email friends and your family about your film. You are also allowed to copy the URL from Tell a Friend window and paste it into an email you created in your favourite email application if you like. Anyone you send to email to will be able to follow the URL directly to your movie. Note: Videos uploaded to YouTube are limited to ten minutes in length and a file size of 2GB. Solution 3: Upload to iMovie after conversion If neither of the above mentioned method works, there is still a third way to turn to. Sometimes, your iMovie files may not be recognized by YouTube due to the versions of iMovie (settings and functions may varies among versions), video itself (video format difference because of file extension, resolution, video size and length), compatibility (videos that are completely incompatible with YouTube). In this circumstance, the best and reliable method is to convert your iMovie files to YouTube accepted files, iMovie to YouTube converter will be inevitably the ideal choice. iMovie to YouTube converter is an elaborately designed tool for convert iMovie files to YouTube workable WMV, 3GP, AVI, MOV, MP4, FLV, MKV for smooth uploading with hard-to-believe conversion speed and second to none output quality. It can also convert between almost all popular popular file formats like AVI, WMV, MPG, MOV, VOB, DV, MP4, FLV, 3GP, RM, ASF, SWF, MP3, AAC, AC3, AIFF, AMR, WAV, WMA etc so as to put on various portable devices, import to video editing software or play on vast amount video players. iMovie to YouTube converter can also served as an excellent video editing tool to meet your specific program requirements. For example, you can cut your video files to a certain length, or split your video files to smaller ones and select the proper resolution suitable for demands of YouTube by Clip or Settings separately. Crop allows you to cut off unwanted black edges from your videos. Besides, you can also have a good command of the whole process or snapshot your favourite pictures from the preview window. More can be expected if you have a try.

  • How can I make a jQuery UI 'draggable()' div draggable for touchscreen?

    - by artlung
    I have a jQuery UI draggable() that works in Firefox and Chrome. The user interface concept is basically click to create a "post-it" type item. Basically, I click or tap on div#everything (100% high and wide) that listens for clicks, and an input textarea displays. You add text, and then when you're done it saves it. You can drag this element around. That is working on normal browsers, but on an iPad I can test with I can't drag the items around. If I touch to select (it then dims slightly), I can't then drag it. It won't drag left or right at all. I can drag up or down, but I'm not dragging the individual div, I'm dragging the whole webpage. So here's the code I use to capture clicks: $('#everything').bind('click', function(e){ var elem = document.createElement('DIV'); STATE.top = e.pageY; STATE.left = e.pageX; var e = $(elem).css({ top: STATE.top, left: STATE.left }).html('<textarea></textarea>') .addClass('instance') .bind('click', function(event){ return false; }); $(this).append(e); }); And here's the code I use to "save" the note and turn the input div into just a display div: $('textarea').live('mouseleave', function(){ var val = jQuery.trim($(this).val()); STATE.content = val; if (val == '') { $(this).parent().remove(); } else { var div = $(this).parent(); div.text(val).css({ height: '30px' }); STATE.height = 30; if ( div.width() !== div[0].clientWidth || div.height () !== div[0].clientHeight ) { while (div.width() !== div[0].clientWidth || div.height () !== div[0].clientHeight) { var h = div.height() + 10; STATE.height = h; div.css({ height: (h) + 'px' }); // element just got scrollbars } } STATE.guid = uniqueID() div.addClass('savedNote').attr('id', STATE.guid).draggable({ stop: function() { var offset = $(this).offset(); STATE.guid = $(this).attr('id'); STATE.top = offset.top; STATE.left = offset.left; STATE.content = $(this).text(); STATE.height = $(this).height(); STATE.save(); } }); STATE.save(); $(this).remove(); } }); And I have this code when I load the page for saved notes: $('.savedNote').draggable({ stop: function() { STATE.guid = $(this).attr('id'); var offset = $(this).offset(); STATE.top = offset.top; STATE.left = offset.left; STATE.content = $(this).text(); STATE.height = $(this).height(); STATE.save(); } }); My STATE object handles saving the notes. Onload, this is the whole html body: <body> <div id="everything"></div> <div class="instance savedNote" id="iddd1b0969-c634-8876-75a9-b274ff87186b" style="top:134px;left:715px;height:30px;">Whatever dude</div> <div class="instance savedNote" id="id8a129f06-7d0c-3cb3-9212-0f38a8445700" style="top:131px;left:347px;height:30px;">Appointment 11:45am</div> <div class="instance savedNote" id="ide92e3d13-afe8-79d7-bc03-818d4c7a471f" style="top:144px;left:65px;height:80px;">What do you think of a board where you can add writing as much as possible?</div> <div class="instance savedNote" id="idef7fe420-4c19-cfec-36b6-272f1e9b5df5" style="top:301px;left:534px;height:30px;">This was submitted</div> <div class="instance savedNote" id="id93b3b56f-5e23-1bd1-ddc1-9be41f1efb44" style="top:390px;left:217px;height:30px;">Hello world from iPad.</div> </body> So, my question is really: how can I make this work better on iPad? I'm not set on jQuery UI, I'm wondering if this is something I'm doing wrong with jQuery UI, or jQuery, or whether there may be better frameworks for doing cross-platform/backward compatible draggable() elements that will work for touchscreen UIs. More general comments about how to write UI components like this would be welcome as well. Thanks!

  • What is the right tool to detect VMT or heap corruption in Delphi ?

    - by Roland Bengtsson
    I'm a member in a team that use Delphi 2007 for a larger application and we suspect heap corruption because sometimes there are strange bugs that have no other explanation. I believe that the Rangechecking option for the compiler is only for arrays. I want a tool that give an exception or log when there is a write on a memory address that is not allocated by the application. Regards EDIT: The error is of type: Error: Access violation at address 00404E78 in module 'BoatLogisticsAMCAttracsServer.exe'. Read of address FFFFFFDD EDIT2: Thanks for all suggestions. Unfortunately I think that the solution is deeper than that. We use a patched version of Bold for Delphi as we own the source. Probably there are some errors introduced in the Bold framwork. Yes we have a log with callstacks that are handled by JCL and also trace messages. So a callstack with the exception can lock like this: 20091210 16:02:29 (2356) [EXCEPTION] Raised EBold: Failed to derive ServerSession.mayDropSession: Boolean OCL expression: not active and not idle and timeout and (ApplicationKernel.allinstances->first.CurrentSession <> self) Error: Access violation at address 00404E78 in module 'BoatLogisticsAMCAttracsServer.exe'. Read of address FFFFFFDD. At Location BoldSystem.TBoldMember.CalculateDerivedMemberWithExpression (BoldSystem.pas:4016) Inner Exception Raised EBold: Failed to derive ServerSession.mayDropSession: Boolean OCL expression: not active and not idle and timeout and (ApplicationKernel.allinstances->first.CurrentSession <> self) Error: Access violation at address 00404E78 in module 'BoatLogisticsAMCAttracsServer.exe'. Read of address FFFFFFDD. At Location BoldSystem.TBoldMember.CalculateDerivedMemberWithExpression (BoldSystem.pas:4016) Inner Exception Call Stack: [00] System.TObject.InheritsFrom (sys\system.pas:9237) Call Stack: [00] BoldSystem.TBoldMember.CalculateDerivedMemberWithExpression (BoldSystem.pas:4016) [01] BoldSystem.TBoldMember.DeriveMember (BoldSystem.pas:3846) [02] BoldSystem.TBoldMemberDeriver.DoDeriveAndSubscribe (BoldSystem.pas:7491) [03] BoldDeriver.TBoldAbstractDeriver.DeriveAndSubscribe (BoldDeriver.pas:180) [04] BoldDeriver.TBoldAbstractDeriver.SetDeriverState (BoldDeriver.pas:262) [05] BoldDeriver.TBoldAbstractDeriver.Derive (BoldDeriver.pas:117) [06] BoldDeriver.TBoldAbstractDeriver.EnsureCurrent (BoldDeriver.pas:196) [07] BoldSystem.TBoldMember.EnsureContentsCurrent (BoldSystem.pas:4245) [08] BoldSystem.TBoldAttribute.EnsureNotNull (BoldSystem.pas:4813) [09] BoldAttributes.TBABoolean.GetAsBoolean (BoldAttributes.pas:3069) [10] BusinessClasses.TLogonSession._GetMayDropSession (code\BusinessClasses.pas:31854) [11] DMAttracsTimers.TAttracsTimerDataModule.RemoveDanglingLogonSessions (code\DMAttracsTimers.pas:237) [12] DMAttracsTimers.TAttracsTimerDataModule.UpdateServerTimeOnTimerTrig (code\DMAttracsTimers.pas:482) [13] DMAttracsTimers.TAttracsTimerDataModule.TimerKernelWork (code\DMAttracsTimers.pas:551) [14] DMAttracsTimers.TAttracsTimerDataModule.AttracsTimerTimer (code\DMAttracsTimers.pas:600) [15] ExtCtrls.TTimer.Timer (ExtCtrls.pas:2281) [16] Classes.StdWndProc (common\Classes.pas:11583) The inner exception part is the callstack at the moment an exception is reraised. EDIT3: The theory right now is that the Virtual Memory Table (VMT) is somehow broken. When this happen there is no indication of it. Only when a method is called an exception is raised (ALWAYS on address FFFFFFDD, -35 decimal) but then it is too late. You don't know the real cause for the error. Any hint of how to catch a bug like this is really appreciated!!! We have tried with SafeMM, but the problem is that the memory consumption is too high even when the 3 GB flag is used. So now I try to give a bounty to the SO community :) EDIT4: One hint is that according the log there is often (or even always) another exception before this. It can be for example optimistic locking in the database. We have tried to raise exceptions by force but in test environment it just works fine. EDIT5: Story continues... I did a search on the logs for the last 30 days now. The result: "Read of address FFFFFFDB" 0 "Read of address FFFFFFDC" 24 "Read of address FFFFFFDD" 270 "Read of address FFFFFFDE" 22 "Read of address FFFFFFDF" 7 "Read of address FFFFFFE0" 20 "Read of address FFFFFFE1" 0 So the current theory is that an enum (there is a lots in Bold) overwrite a pointer. I got 5 hits with different address above. It could mean that the enum holds 5 values where the second one is most used. If there is an exception a rollback should occur for the database and Boldobjects should be destroyed. Maybe there is a chance that not everything is destroyed and a enum still can write to an address location. If this is true maybe it is possible to search the code by a regexpr for an enum with 5 values ? EDIT6: To summarize, no there is no solution to the problem yet. I realize that I may mislead you a bit with the callstack. Yes there are a timer in that but there are other callstacks without a timer. Sorry for that. But there are 2 common factors. An exception with Read of address FFFFFFxx. Top of callstack is System.TObject.InheritsFrom (sys\system.pas:9237) This convince me that VilleK best describe the problem. I'm also convinced that the problem is somewhere in the Bold framework. But the BIG question is, how can problems like this be solved ? It is not enough to have an Assert like VilleK suggest as the damage has already happened and the callstack is gone at that moment. So to describe my view of what may cause the error: Somewhere a pointer is assigned a bad value 1, but it can be also 0, 2, 3 etc. An object is assigned to that pointer. There is method call in the objects baseclass. This cause method TObject.InheritsForm to be called and an exception appear on address FFFFFFDD. Those 3 events can be together in the code but they may also be used much later. I think this is true for the last method call. EDIT7: We work closely with the the author of Bold Jan Norden and he recently found a bug in the OCL-evaluator in Bold framework. When this was fixed these kinds of exceptions decreased a lot but they still occasionally come. But it is a big relief that this is almost solved.

  • mfc tab control switch tabs

    - by MRM
    I created a simple tab control that has 2 tabs (each tab is a different dialog). The thing is that i don't have any idea how to switch between tabs (when the user presses Titlu Tab1 to show the dialog i made for the first tab, and when it presses Titlu Tab2 to show my other dialog). I added a handler for changing items, but i don't know how should i acces some kind of index or child for tabs. Tab1.h and Tab2.h are headers for dialogs that show only static texts with the name of the each tab. There may be an obvious answer to my question, but i am a real newbie in c++ and MFC. This is my header: // CTabControlDlg.h : header file // #pragma once #include "afxcmn.h" #include "Tab1.h" #include "Tab2.h" // CCTabControlDlg dialog class CCTabControlDlg : public CDialog { // Construction public: CCTabControlDlg(CWnd* pParent = NULL); // standard constructor // Dialog Data enum { IDD = IDD_CTABCONTROL_DIALOG }; protected: virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support // Implementation protected: HICON m_hIcon; // Generated message map functions virtual BOOL OnInitDialog(); afx_msg void OnSysCommand(UINT nID, LPARAM lParam); afx_msg void OnPaint(); afx_msg HCURSOR OnQueryDragIcon(); DECLARE_MESSAGE_MAP() public: CTabCtrl m_tabcontrol1; CTab1 m_tab1; CTab2 m_tab2; afx_msg void OnTcnSelchangeTabcontrol(NMHDR *pNMHDR, LRESULT *pResult); }; And this is the .cpp: // CTabControlDlg.cpp : implementation file // #include "stdafx.h" #include "CTabControl.h" #include "CTabControlDlg.h" #ifdef _DEBUG #define new DEBUG_NEW #endif // CAboutDlg dialog used for App About class CAboutDlg : public CDialog { public: CAboutDlg(); // Dialog Data enum { IDD = IDD_ABOUTBOX }; protected: virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support // Implementation protected: DECLARE_MESSAGE_MAP() }; CAboutDlg::CAboutDlg() : CDialog(CAboutDlg::IDD) { } void CAboutDlg::DoDataExchange(CDataExchange* pDX) { CDialog::DoDataExchange(pDX); } BEGIN_MESSAGE_MAP(CAboutDlg, CDialog) END_MESSAGE_MAP() // CCTabControlDlg dialog CCTabControlDlg::CCTabControlDlg(CWnd* pParent /*=NULL*/) : CDialog(CCTabControlDlg::IDD, pParent) { m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME); } void CCTabControlDlg::DoDataExchange(CDataExchange* pDX) { CDialog::DoDataExchange(pDX); DDX_Control(pDX, IDC_TABCONTROL, m_tabcontrol1); } BEGIN_MESSAGE_MAP(CCTabControlDlg, CDialog) ON_WM_SYSCOMMAND() ON_WM_PAINT() ON_WM_QUERYDRAGICON() //}}AFX_MSG_MAP ON_NOTIFY(TCN_SELCHANGE, IDC_TABCONTROL, &CCTabControlDlg::OnTcnSelchangeTabcontrol) END_MESSAGE_MAP() // CCTabControlDlg message handlers BOOL CCTabControlDlg::OnInitDialog() { CDialog::OnInitDialog(); // Add "About..." menu item to system menu. // IDM_ABOUTBOX must be in the system command range.

  • Few Google Checkout Questions

    - by Richard Knop
    I am planning to integrate a Google Checkout payment system on a social networking website. The idea is that members can buy "tokens" for real money (which are sort of the website currency) and then they can buy access to some extra content on the website etc. What I want to do is create a Google Checkout button that takes a member to the checkout page where he pays with his credit or debit card. What I want is the Google Checkout to notify notify my server whether the purchase of tokens was successful (if the credit/debit card was charged) so I can update the local database. The website is coded in PHP/MySQL. I have downloaded the sample PHP code from here: code.google.com/p/google-checkout-php-sample-code/wiki/Documentation I know how to create a Google checkout button and I have also placed the responsehandlerdemo.php file on my server. This is the file the Google Checkout is supposed to send response to (of course I set the path to the file in Google merchant account). Now in the response handler file there is a switch block with several case statements. Which one means that the payment was successful and I can add tokens to the member account in the local database? switch ($root) { case "request-received": { break; } case "error": { break; } case "diagnosis": { break; } case "checkout-redirect": { break; } case "merchant-calculation-callback": { // Create the results and send it $merchant_calc = new GoogleMerchantCalculations($currency); // Loop through the list of address ids from the callback $addresses = get_arr_result($data[$root]['calculate']['addresses']['anonymous-address']); foreach($addresses as $curr_address) { $curr_id = $curr_address['id']; $country = $curr_address['country-code']['VALUE']; $city = $curr_address['city']['VALUE']; $region = $curr_address['region']['VALUE']; $postal_code = $curr_address['postal-code']['VALUE']; // Loop through each shipping method if merchant-calculated shipping // support is to be provided if(isset($data[$root]['calculate']['shipping'])) { $shipping = get_arr_result($data[$root]['calculate']['shipping']['method']); foreach($shipping as $curr_ship) { $name = $curr_ship['name']; //Compute the price for this shipping method and address id $price = 12; // Modify this to get the actual price $shippable = "true"; // Modify this as required $merchant_result = new GoogleResult($curr_id); $merchant_result->SetShippingDetails($name, $price, $shippable); if($data[$root]['calculate']['tax']['VALUE'] == "true") { //Compute tax for this address id and shipping type $amount = 15; // Modify this to the actual tax value $merchant_result->SetTaxDetails($amount); } if(isset($data[$root]['calculate']['merchant-code-strings'] ['merchant-code-string'])) { $codes = get_arr_result($data[$root]['calculate']['merchant-code-strings'] ['merchant-code-string']); foreach($codes as $curr_code) { //Update this data as required to set whether the coupon is valid, the code and the amount $coupons = new GoogleCoupons("true", $curr_code['code'], 5, "test2"); $merchant_result->AddCoupons($coupons); } } $merchant_calc->AddResult($merchant_result); } } else { $merchant_result = new GoogleResult($curr_id); if($data[$root]['calculate']['tax']['VALUE'] == "true") { //Compute tax for this address id and shipping type $amount = 15; // Modify this to the actual tax value $merchant_result->SetTaxDetails($amount); } $codes = get_arr_result($data[$root]['calculate']['merchant-code-strings'] ['merchant-code-string']); foreach($codes as $curr_code) { //Update this data as required to set whether the coupon is valid, the code and the amount $coupons = new GoogleCoupons("true", $curr_code['code'], 5, "test2"); $merchant_result->AddCoupons($coupons); } $merchant_calc->AddResult($merchant_result); } } $Gresponse->ProcessMerchantCalculations($merchant_calc); break; } case "new-order-notification": { $Gresponse->SendAck(); break; } case "order-state-change-notification": { $Gresponse->SendAck(); $new_financial_state = $data[$root]['new-financial-order-state']['VALUE']; $new_fulfillment_order = $data[$root]['new-fulfillment-order-state']['VALUE']; switch($new_financial_state) { case 'REVIEWING': { break; } case 'CHARGEABLE': { //$Grequest->SendProcessOrder($data[$root]['google-order-number']['VALUE']); //$Grequest->SendChargeOrder($data[$root]['google-order-number']['VALUE'],''); break; } case 'CHARGING': { break; } case 'CHARGED': { break; } case 'PAYMENT_DECLINED': { break; } case 'CANCELLED': { break; } case 'CANCELLED_BY_GOOGLE': { //$Grequest->SendBuyerMessage($data[$root]['google-order-number']['VALUE'], // "Sorry, your order is cancelled by Google", true); break; } default: break; } switch($new_fulfillment_order) { case 'NEW': { break; } case 'PROCESSING': { break; } case 'DELIVERED': { break; } case 'WILL_NOT_DELIVER': { break; } default: break; } break; } case "charge-amount-notification": { //$Grequest->SendDeliverOrder($data[$root]['google-order-number']['VALUE'], // <carrier>, <tracking-number>, <send-email>); //$Grequest->SendArchiveOrder($data[$root]['google-order-number']['VALUE'] ); $Gresponse->SendAck(); break; } case "chargeback-amount-notification": { $Gresponse->SendAck(); break; } case "refund-amount-notification": { $Gresponse->SendAck(); break; } case "risk-information-notification": { $Gresponse->SendAck(); break; } default: $Gresponse->SendBadRequestStatus("Invalid or not supported Message"); break; } I guess that case 'CHARGED' is the one, am I right? Second question, do I need an SSL certificate to receive response from Google Checkout? According to this I do: groups.google.com/group/google-checkout-api-php/browse_thread/thread/10ce55177281c2b0 But I don's see it mentioned anywhere in the official documentation. Thank you.

  • Resulting .exe from PyInstaller with wxPython crashing

    - by Helgi Hrafn Gunnarsson
    I'm trying to compile a very simple wxPython script into an executable by using PyInstaller on Windows Vista. The Python script is nothing but a Hello World in wxPython. I'm trying to get that up and running as a Windows executable before I add any of the features that the program needs to have. But I'm already stuck. I've jumped through some loops in regards to MSVCR90.DLL, MSVCP90.DLL and MSVCPM90.DLL, which I ended up copying from my Visual Studio installation (C:\Program Files\Microsoft Visual Studio 9.0\VC\redist\x86\Microsoft.VC90.CRT). As according to the instructions for PyInstaller, I run: Command: Configure.py Output: I: computing EXE_dependencies I: Finding TCL/TK... I: could not find TCL/TK I: testing for Zlib... I: ... Zlib available I: Testing for ability to set icons, version resources... I: ... resource update available I: Testing for Unicode support... I: ... Unicode available I: testing for UPX...

It's just one of those standard Windows Vista crashes. The script itself, guitest.py runs just fine by itself. It only crashes as an executable, and I'm completely lost. I don't even know what to look for, since nothing I've tried has returned any relevant results. Another file is generated as a result of the compilation process, called 'warnguitest.txt'.

Again, my searches have been fruitless.

  • What strategy do you use for package naming in Java projects and why?

    - by Tim Visher
    I thought about this awhile ago and it recently resurfaced as my shop is doing its first real Java web app. As an intro, I see two main package naming strategies. (To be clear, I'm not referring to the whole 'domain.company.project' part of this, I'm talking about the package convention beneath that.) Anyway, the package naming conventions that I see are as follows: Functional: Naming your packages according to their function architecturally rather than their identity according to the business domain. Another term for this might be naming according to 'layer'. So, you'd have a *.ui package and a *.domain package and a *.orm package. Your packages are horizontal slices rather than vertical. This is much more common than logical naming. In fact, I don't believe I've ever seen or heard of a project that does this. This of course makes me leery (sort of like thinking that you've come up with a solution to an NP problem) as I'm not terribly smart and I assume everyone must have great reasons for doing it the way they do. On the other hand, I'm not opposed to people just missing the elephant in the room and I've never heard a an actual argument for doing package naming this way. It just seems to be the de facto standard. Logical: Naming your packages according to their business domain identity and putting every class that has to do with that vertical slice of functionality into that package. I have never seen or heard of this, as I mentioned before, but it makes a ton of sense to me. I tend to approach systems vertically rather than horizontally. I want to go in and develop the Order Processing system, not the data access layer. Obviously, there's a good chance that I'll touch the data access layer in the development of that system, but the point is that I don't think of it that way. What this means, of course, is that when I receive a change order or want to implement some new feature, it'd be nice to not have to go fishing around in a bunch of packages in order to find all the related classes. Instead, I just look in the X package because what I'm doing has to do with X. From a development standpoint, I see it as a major win to have your packages document your business domain rather than your architecture. I feel like the domain is almost always the part of the system that's harder to grok where as the system's architecture, especially at this point, is almost becoming mundane in its implementation. The fact that I can come to a system with this type of naming convention and instantly from the naming of the packages know that it deals with orders, customers, enterprises, products, etc. seems pretty darn handy. It seems like this would allow you to take much better advantage of Java's access modifiers. This allows you to much more cleanly define interfaces into subsystems rather than into layers of the system. So if you have an orders subsystem that you want to be transparently persistent, you could in theory just never let anything else know that it's persistent by not having to create public interfaces to its persistence classes in the dao layer and instead packaging the dao class in with only the classes it deals with. Obviously, if you wanted to expose this functionality, you could provide an interface for it or make it public. It just seems like you lose a lot of this by having a vertical slice of your system's features split across multiple packages. I suppose one disadvantage that I can see is that it does make ripping out layers a little bit more difficult. Instead of just deleting or renaming a package and then dropping a new one in place with an alternate technology, you have to go in and change all of the classes in all of the packages. However, I don't see this is a big deal. It may be from a lack of experience, but I have to imagine that the amount of times you swap out technologies pales in comparison to the amount of times you go in and edit vertical feature slices within your system. So I guess the question then would go out to you, how do you name your packages and why? Please understand that I don't necessarily think that I've stumbled onto the golden goose or something here. I'm pretty new to all this with mostly academic experience. However, I can't spot the holes in my reasoning so I'm hoping you all can so that I can move on. Thanks in advance!

  • Should I refactor this code?

    - by user156814
    The code is for a view debate page. The code is supposed to determine whether or not to show an add reply form to the viewing user. If the user is logged in, and the user is not the creator of the debate, then check if the user already replied to the debate. If the user did not already reply to the debate then show the form... Otherwise, Check If the user wants to edit their already existing reply by looking in the url for the reply id If any of these tests dont pass, Then I save the reason as an int and pass that to a switch statement in the view. The logic seems easy enough, but my code seems a little sloppy. Here's the code.. (using Kohana V2.3.4) public function view($id = 0) { $debate = ORM::factory('debate')->with('user')->with('category')->find($id); if ($debate->loaded == FALSE) { url::redirect(); } // series of tests to show an add reply form if ($this->logged_in) { // is the viewer the creator? if ($this->user->id != $debate->user->id) { // has the user already replied? if (ORM::factory('reply') ->where(array('debate_id' => $id, 'user_id' => $this->user->id)) ->count_all() == 0) { $form = $errors = array ( 'body' => '', 'choice_id' => '', 'add' => '' ); if ($post = $this->input->post()) { $reply = ORM::factory('reply'); // validate and insert the reply if ($reply->add($post, TRUE)) { url::redirect(url::current()); } $form = arr::overwrite($form, $post->as_array()); $errors = arr::overwrite($errors, $post->errors('reply_errors')); } } // editing a reply? else if (($rid = (int) $this->input->get('edit')) AND ($reply = ORM::factory('reply') ->where(array('debate_id' => $id, 'user_id' => $this->user->id)) ->find($rid))) { $form = $errors = array ( 'body' => '', 'choice_id' => '', 'add' => '' ); // autocomplete the form $form = arr::overwrite($form, $reply->as_array()); if ($post = $this->input->post()) { // validate and insert the reply if ($reply->edit($post, TRUE)) { url::redirect(url::current()); } $form = arr::overwrite($form, $post->as_array()); $errors = arr::overwrite($errors, $post->errors('reply_errors')); } } else { // user already replied $reason = 3; } } else { // user started the debate $reason = 2; } } else { // user is not logged in. $reason = 1; } $limits = Kohana::config('app/debate.limits'); $page = (int) $this->input->get('page', 1); $offset = ($page > 0) ? ($page - 1) * $limits['replies'] : 0; $replies = ORM::factory('reply')->with('user')->with('choice')->where('replies.debate_id', $id); $this->template->title = $debate->topic; $this->template->debate = $debate; $this->template->body = View::factory('debate/view') ->set('debate', $debate) ->set('replies', $replies->find_all($limits['replies'], $offset)) ->set('pagination', Pagination::factory(array ( 'style' => 'digg', 'items_per_page' => $limits['replies'], 'query_string' => 'page', 'auto_hide' => TRUE, 'total_items' => $total = $replies->count_last_query() )) ) ->set('total', $total); // are we showing the add reply form? if (isset($form, $errors)) { $this->template->body->add_reply_form = View::factory('reply/add_reply_form') ->set('debate', $debate) ->set('form', $form) ->set('errors', $errors); } else { $this->template->body->reason = $reason; } } Heres the view, theres some logic in here that determines what message to show the user. <!-- Add Reply Form --> <?php if (isset($add_reply_form)): ?> <?php echo $add_reply_form; ?> <?php else: ?> <?php switch ($reason) { case 1 : // not logged in, show a message $message = 'Add your ' . html::anchor('login?url=' . url::current(TRUE), '<b>vote</b>') . ' to this discussion'; break; case 2 : // started the debate. dont show a message for that. $message = NULL; break; case 3: // already replied, show a message $message = 'You have already replied to this debate'; break; default: // unknown reason. dont show a message $message = NULL; break; } ?> <?php echo app::show_message($message, 'h2'); ?> <?php endif; ?> <!-- End Add Reply Form --> Should I refactor the add reply logic into another function or something.... It all works, it just seems real sloppy. Thanks

  • HttpModule Init method is called several times - why?

    - by MartinF
    I was creating a http module and while debugging I noticed something which at first (at least) seemed like weird behaviour. When i set a breakpoint in the init method of the httpmodule i can see that the http module init method is being called several times even though i have only started up the website for debugging and made one single request (sometimes it is hit only 1 time, other times as many as 10 times). I know that I should expect several instances of the HttpApplication to be running and for each the http modules will be created, but when i request a single page it should be handled by a single http application object and therefore only fire the events associated once, but still it fires the events several times for each request which makes no sense - other than it must have been added several times within that httpApplication - which means it is the same httpmodule init method which is being called every time and not a new http application being created each time it hits my break point (see my code example at the bottom etc.). What could be going wrong here ? is it because i am debugging and set a breakpoint in the http module? It have noticed that it seems that if i startup the website for debugging and quickly step over the breakpoint in the httpmodule it will only hit the init method once and the same goes for the eventhandler. If I instead let it hang at the breakpoint for a few seconds the init method is being called several times (seems like it depends on how long time i wait before stepping over the breakpoint). Maybe this could be some build in feature to make sure that the httpmodule is initialised and the http application can serve requests , but it also seems like something that could have catastrophic consequences. This could seem logical, as it might be trying to finish the request and since i have set the break point it thinks something have gone wrong and try to call the init method again ? soo it can handle the request ? But is this what is happening and is everything fine (i am just guessing), or is it a real problem ? What i am specially concerned about is that if something makes it hang on the "production/live" server for a few seconds a lot of event handlers are added through the init and therefore each request to the page suddenly fires the eventhandler several times. This behaviour could quickly bring any site down. I have looked at the "original" .net code used for the httpmodules for formsauthentication and the rolemanagermodule etc but my code isnt any different that those modules uses. My code looks like this. public void Init(HttpApplication app) { if (CommunityAuthenticationIntegration.IsEnabled) { FormsAuthenticationModule formsAuthModule = (FormsAuthenticationModule) app.Modules["FormsAuthentication"]; formsAuthModule.Authenticate += new FormsAuthenticationEventHandler(this.OnAuthenticate); } } here is an example how it is done in the RoleManagerModule from the .NET framework public void Init(HttpApplication app) { if (Roles.Enabled) { app.PostAuthenticateRequest += new EventHandler(this.OnEnter); app.EndRequest += new EventHandler(this.OnLeave); } } Do anyone know what is going on? (i just hope someone out there can tell me why this is happening and assure me that everything is perfectly fine) :) UPDATE: I have tried to narrow down the problem and so far i have found that the Init method being called is always on a new object of my http module (contary to what i thought before). I seems that for the first request (when starting up the site) all of the HttpApplication objects being created and its modules are all trying to serve the first request and therefore all hit the eventhandler that is being added. I cant really figure out why this is happening. If i request another page all the HttpApplication's created (and their moduless) will again try to serve the request causing it to hit the eventhandler multiple times. But it also seems that if i then jump back to the first page (or another one) only one HttpApplication will start to take care of the request and everything is as expected - as long as i dont let it hang at a break point. If i let it hang at a breakpoint it begins to create new HttpApplication's objects and starts adding HttpApplications (more than 1) to serve/handle the request (which is already in process of being served by the HttpApplication which is currently stopped at the breakpoint). I guess or hope that it might be some intelligent "behind the scenes" way of helping to distribute and handle load and / or errors. But I have no clue. I hope some out there can assure me that it is perfectly fine and how it is supposed to be?

  • iPhone OpenGL ES freezes for no reason

    - by KJ
    Hi, I'm quite new to iPhone OpenGL ES, and I'm really stuck. I was trying to implement shadow mapping on iPhone, and I allocated two 512*1024*32bit textures for the shadow map and the diffuse map respectively. The problem is that my application started to freeze and reboot the device after I added the shadow map allocation part to the code (so I guess the shadow map allocation is causing all this mess). It happens randomly, but mostly within 10 minutes. (sometimes within a few secs) And it only happens on the real iPhone device, not on the virtual device. I backtracked the problem by removing irrelevant code lines by lines and now my code is really simple, but it's still crashing (I mean, freezing). Could anybody please download my xcode project linked below and see what on earth is wrong? The code is really simple: http://www.tempfiles.net/download/201004/95922/CrashTest.html I would really appreciate if someone can help me. My iPhone is a 3GS and running on the OS version 3.1. Again, run the code and it'll take about 5 mins in average for the device to freeze and reboot. (Don't worry, it does no harm) It'll just display cyan screen before it freezes, but you'll be able to notice when it happens because the device will reboot soon, so please be patient. Just in case you can't reproduce the problem, please let me know.

  • Avoiding Agnostic Jagged Array Flattening in Powershell

    - by matejhowell
    Hello, I'm running into an interesting problem in Powershell, and haven't been able to find a solution to it. When I google (and find things like this post), nothing quite as involved as what I'm trying to do comes up, so I thought I'd post the question here. The problem has to do with multidimensional arrays with an outer array length of one. It appears Powershell is very adamant about flattening arrays like @( @('A') ) becomes @( 'A' ). Here is the first snippet (prompt is , btw): > $a = @( @( 'Test' ) ) > $a.gettype().isarray True > $a[0].gettype().isarray False So, I'd like to have $a[0].gettype().isarray be true, so that I can index the value as $a[0][0] (the real world scenario is processing dynamic arrays inside of a loop, and I'd like to get the values as $a[$i][$j], but if the inner item is not recognized as an array but as a string (in my case), you start indexing into the characters of the string, as in $a[0][0] -eq 'T'). I have a couple of long code examples, so I have posted them at the end. And, for reference, this is on Windows 7 Ultimate with PSv2 and PSCX installed. Consider code example 1: I build a simple array manually using the += operator. Intermediate array $w is flattened, and consequently is not added to the final array correctly. I have found solutions online for similar problems, which basically involve putting a comma before the inner array to force the outer array to not flatten, which does work, but again, I'm looking for a solution that can build arrays inside a loop (a jagged array of arrays, processing a CSS file), so if I add the leading comma to the single element array (implemented as intermediate array $y), I'd like to do the same for other arrays (like $z), but that adversely affects how $z is added to the final array. Now consider code example 2: This is closer to the actual problem I am having. When a multidimensional array with one element is returned from a function, it is flattened. It is correct before it leaves the function. And again, these are examples, I'm really trying to process a file without having to know if the function is going to come back with @( @( 'color', 'black') ) or with @( @( 'color', 'black'), @( 'background-color', 'white') ) Has anybody encountered this, and has anybody resolved this? I know I can instantiate framework objects, and I'm assuming everything will be fine if I create an object[], or a list<, or something else similar, but I've been dealing with this for a little bit and something sure seems like there has to be a right way to do this (without having to instantiate true framework objects). Code Example 1 function Display($x, [int]$indent, [string]$title) { if($title -ne '') { write-host "$title`: " -foregroundcolor cyan -nonewline } if(!$x.GetType().IsArray) { write-host "'$x'" -foregroundcolor cyan } else { write-host '' $s = new-object string(' ', $indent) for($i = 0; $i -lt $x.length; $i++) { write-host "$s[$i]: " -nonewline -foregroundcolor cyan Display $x[$i] $($indent+1) } } if($title -ne '') { write-host '' } } ### Start Program $final = @( @( 'a', 'b' ), @('c')) Display $final 0 'Initial Value' ### How do we do this part ??? ########### ## $w = @( @('d', 'e') ) ## $x = @( @('f', 'g'), @('h') ) ## # But now $w is flat, $w.length = 2 ## ## ## # Even if we put a leading comma (,) ## # in front of the array, $y will work ## # but $w will not. This can be a ## # problem inside a loop where you don't ## # know the length of the array, and you ## # need to put a comma in front of ## # single- and multidimensional arrays. ## $y = @( ,@('D', 'E') ) ## $z = @( ,@('F', 'G'), @('H') ) ## ## ## ########################################## $final += $w $final += $x $final += $y $final += $z Display $final 0 'Final Value' ### Desired final value: @( @('a', 'b'), @('c'), @('d', 'e'), @('f', 'g'), @('h'), @('D', 'E'), @('F', 'G'), @('H') ) ### As in the below: # # Initial Value: # [0]: # [0]: 'a' # [1]: 'b' # [1]: # [0]: 'c' # # Final Value: # [0]: # [0]: 'a' # [1]: 'b' # [1]: # [0]: 'c' # [2]: # [0]: 'd' # [1]: 'e' # [3]: # [0]: 'f' # [1]: 'g' # [4]: # [0]: 'h' # [5]: # [0]: 'D' # [1]: 'E' # [6]: # [0]: 'F' # [1]: 'G' # [7]: # [0]: 'H' Code Example 2 function Display($x, [int]$indent, [string]$title) { if($title -ne '') { write-host "$title`: " -foregroundcolor cyan -nonewline } if(!$x.GetType().IsArray) { write-host "'$x'" -foregroundcolor cyan } else { write-host '' $s = new-object string(' ', $indent) for($i = 0; $i -lt $x.length; $i++) { write-host "$s[$i]: " -nonewline -foregroundcolor cyan Display $x[$i] $($indent+1) } } if($title -ne '') { write-host '' } } function funA() { $ret = @() $temp = @(0) $temp[0] = @('p', 'q') $ret += $temp Display $ret 0 'Inside Function A' return $ret } function funB() { $ret = @( ,@('r', 's') ) Display $ret 0 'Inside Function B' return $ret } ### Start Program $z = funA Display $z 0 'Return from Function A' $z = funB Display $z 0 'Return from Function B' ### Desired final value: @( @('p', 'q') ) and same for r,s ### As in the below: # # Inside Function A: # [0]: # [0]: 'p' # [1]: 'q' # # Return from Function A: # [0]: # [0]: 'p' # [1]: 'q' Thanks, Matt

  • Prefer extension methods for encapsulation and reusability?

    - by tzaman
    edit4: wikified, since this seems to have morphed more into a discussion than a specific question. In C++ programming, it's generally considered good practice to "prefer non-member non-friend functions" instead of instance methods. This has been recommended by Scott Meyers in this classic Dr. Dobbs article, and repeated by Herb Sutter and Andrei Alexandrescu in C++ Coding Standards (item 44); the general argument being that if a function can do its job solely by relying on the public interface exposed by the class, it actually increases encapsulation to have it be external. While this confuses the "packaging" of the class to some extent, the benefits are generally considered worth it. Now, ever since I've started programming in C#, I've had a feeling that here is the ultimate expression of the concept that they're trying to achieve with "non-member, non-friend functions that are part of a class interface". C# adds two crucial components to the mix - the first being interfaces, and the second extension methods: Interfaces allow a class to formally specify their public contract, the methods and properties that they're exposing to the world. Any other class can choose to implement the same interface and fulfill that same contract. Extension methods can be defined on an interface, providing any functionality that can be implemented via the interface to all implementers automatically. And best of all, because of the "instance syntax" sugar and IDE support, they can be called the same way as any other instance method, eliminating the cognitive overhead! So you get the encapsulation benefits of "non-member, non-friend" functions with the convenience of members. Seems like the best of both worlds to me; the .NET library itself providing a shining example in LINQ. However, everywhere I look I see people warning against extension method overuse; even the MSDN page itself states: In general, we recommend that you implement extension methods sparingly and only when you have to. (edit: Even in the current .NET library, I can see places where it would've been useful to have extensions instead of instance methods - for example, all of the utility functions of List<T> (Sort, BinarySearch, FindIndex, etc.) would be incredibly useful if they were lifted up to IList<T> - getting free bonus functionality like that adds a lot more benefit to implementing the interface.) So what's the verdict? Are extension methods the acme of encapsulation and code reuse, or am I just deluding myself? (edit2: In response to Tomas - while C# did start out with Java's (overly, imo) OO mentality, it seems to be embracing more multi-paradigm programming with every new release; the main thrust of this question is whether using extension methods to drive a style change (towards more generic / functional C#) is useful or worthwhile..) edit3: overridable extension methods The only real problem identified so far with this approach, is that you can't specialize extension methods if you need to. I've been thinking about the issue, and I think I've come up with a solution. Suppose I have an interface MyInterface, which I want to extend - I define my extension methods in a MyExtension static class, and pair it with another interface, call it MyExtensionOverrider. MyExtension methods are defined according to this pattern: public static int MyMethod(this MyInterface obj, int arg, bool attemptCast=true) { if (attemptCast && obj is MyExtensionOverrider) { return ((MyExtensionOverrider)obj).MyMethod(arg); } // regular implementation here } The override interface mirrors all of the methods defined in MyExtension, except without the this or attemptCast parameters: public interface MyExtensionOverrider { int MyMethod(int arg); string MyOtherMethod(); } Now, any class can implement the interface and get the default extension functionality: public class MyClass : MyInterface { ... } Anyone that wants to override it with specific implementations can additionally implement the override interface: public class MySpecializedClass : MyInterface, MyExtensionOverrider { public int MyMethod(int arg) { //specialized implementation for one method } public string MyOtherMethod() { // fallback to default for others MyExtension.MyOtherMethod(this, attemptCast: false); } } And there we go: extension methods provided on an interface, with the option of complete extensibility if needed. Fully general too, the interface itself doesn't need to know about the extension / override, and multiple extension / override pairs can be implemented without interfering with each other. I can see three problems with this approach - It's a little bit fragile - the extension methods and override interface have to be kept synchronized manually. It's a little bit ugly - implementing the override interface involves boilerplate for every function you don't want to specialize. It's a little bit slow - there's an extra bool comparison and cast attempt added to the mainline of every method. Still, all those notwithstanding, I think this is the best we can get until there's language support for interface functions. Thoughts?

  • Convert C++Builder AnsiString to std::string via boost::lexical_cast

    - by David Klein
    For a school assignment I have to implement a project in C++ using Borland C++ Builder. As the VCL uses AnsiString for all GUI Components I have to convert all of my std::strings to AnsiString for the sake of displaying. std::string inp = "Hello world!"; AnsiString outp(inp.c_str()); works of course but is a bit tedious to write and code duplication I want to avoid. As we use Boost in other contexts I decided to provide some helper functions go get boost::lexical_cast to work with AnsiString. Here is my implementation so far: std::istream& operator>>(std::istream& istr, AnsiString& str) { istr.exceptions(std::ios::badbit | std::ios::failbit | std::ios::eofbit); std::string s; std::getline(istr,s); str = AnsiString(s.c_str()); return istr; } In the beginning I got Access Violation after Access Violation but since I added the .exceptions() stuff the picture gets clearer. When the conversion is performed I get the following Exception: ios_base::eofbit set [Runtime Error/std::ios_base::failure] Does anyone have an idea how to fix it and can explain why the error occurs? My C++ experience is very limited. The conversion routine the other way round would be: std::ostream& operator<<(std::ostream& ostr,const AnsiString& str) { ostr << (str.c_str()); return ostr; } Maybe someone will spot an error here too :) With best regards! Edit: At the moment I'm using the edited version of Jem, it works in the beginning. After a while of using the programm the Borland Codeguard mentions some pointer arithmetic in already freed regions. Any ideas how this could be related?

  • Asp.net Google Charts SSL handler for GeoMap

    - by Ian
    Hi All, I am trying to view Google charts in a site using SSL. Google Charts do not support SSL so if we use the standard charts, we get warning messages. My plan is to create a ASHX handler that is co9ntained in the secure site that will retrieve the content from Google and serve this to the page the user is viewing. Using VS 2008 SP1 and the included web server, my idea works perfectly for both Firefox and IE 8 & 9(Preview) and I am able to see my geomap displayed on my page as it should be. But my problem is when I publish to IIS7 the page using my handler to generate the geomap works in Firefox but not IE(every version). There are no errors anywhere or in any log files, but when i right click in IE in the area where the map should be displayed, I see the message in the context menu saying "movie not loaded" Below is the code from my handler and the aspx page. I have disabled compression in my web.config. Even in IE I am hitting all my break points and when I use the IE9 Developer tools, the web page is correctly generated with all the correct code, url's and references. If you have any better ways to accomplish this or how i can fix my problem, I will appreciate it.

  • problem in loading images from web

    - by Lynnooi
    hi, I am new in android and had developed an app which get images from the website and display it. I got it working in emulator but not in real phones. In some device, it will crash or take very long loading period. Can anyone please help me or guide me in improving it as i'm not sure whether the way i loads the images is correct or not. Here are the code i use to get the images from the web and display accordingly. if (xmlURL.length() != 0) { try { URL url = new URL(xmlURL); SAXParserFactory spf = SAXParserFactory.newInstance(); SAXParser sp = spf.newSAXParser(); /* Get the XMLReader of the SAXParser we created. */ XMLReader xr = sp.getXMLReader(); /* * Create a new ContentHandler and apply it to the * XML-Reader */ xr.setContentHandler(myExampleHandler); /* Parse the xml-data from our URL. */ xr.parse(new InputSource(url.openStream())); /* Parsing has finished. */ /* * Our ExampleHandler now provides the parsed data to * us. */ ParsedExampleDataSet parsedExampleDataSet = myExampleHandler.getParsedData(); } catch (Exception e) { } } if (s.equalsIgnoreCase("wallpapers")) { Context context = helloAndroid.this.getBaseContext(); for (int j = 0; j <= myExampleHandler.filenames.size() - 1; j++) { if (myExampleHandler.filenames.elementAt(j).toString() != null) { helloAndroid.this.ed = myExampleHandler.thumbs.elementAt(j) .toString(); if (helloAndroid.this.ed.length() != 0) { Drawable image = ImageOperations(context, helloAndroid.this.ed, "image.jpg"); file_info = myExampleHandler.filenames .elementAt(j).toString(); author = "\nby " + myExampleHandler.authors.elementAt(j) .toString(); switch (j + 1) { case 1: ImageView imgView1 = new ImageView(context); imgView1 = (ImageView) findViewById(R.id.image1); if (image.getIntrinsicHeight() > 0) { imgView1.setImageDrawable(image); } else imgView1 .setImageResource(R.drawable.empty_wallpaper); tv = (TextView) findViewById(R.id.filename1); tv.setText(file_info); tv = (TextView) findViewById(R.id.author1); tv.setText(author); imgView1 .setOnClickListener(new View.OnClickListener() { public void onClick(View view) { // Perform action on click Intent myIntent1 = new Intent( helloAndroid.this, galleryFile.class); Bundle b = new Bundle(); b.putString("fileID",myExampleHandler.fileid.elementAt(0).toString()); b.putString("page", "1"); b.putString("family", s); b.putString("fi",myExampleHandler.folder_id.elementAt(folder).toString()); b.putString("kw", keyword); myIntent1.putExtras(b); startActivityForResult( myIntent1, 0); } }); break; case 2: ImageView imgView2 = new ImageView(context); imgView2 = (ImageView) findViewById(R.id.image2); imgView2.setImageDrawable(image); tv = (TextView) findViewById(R.id.filename2); tv.setText(file_info); tv = (TextView) findViewById(R.id.author2); tv.setText(author); imgView2 .setOnClickListener(new View.OnClickListener() { public void onClick(View view) { // Perform action on click Intent myIntent1 = new Intent( helloAndroid.this, galleryFile.class); Bundle b = new Bundle(); b.putString("fileID",myExampleHandler.fileid.elementAt(1).toString()); b.putString("page", "1"); b.putString("family", s); b.putString("fi",myExampleHandler.folder_id.elementAt(folder).toString()); b.putString("kw", keyword); myIntent1.putExtras(b); startActivityForResult( myIntent1, 0); } }); break; case 3: //same code break; } } } } } private Drawable ImageOperations(Context ctx, String url, String saveFilename) { try { InputStream is = (InputStream) this.fetch(url); Drawable d = Drawable.createFromStream(is, "src"); return d; } catch (MalformedURLException e) { e.printStackTrace(); return null; } catch (IOException e) { e.printStackTrace(); return null; } } public Object fetch(String address) throws MalformedURLException, IOException { URL url = new URL(address); Object content = url.getContent(); return content; }

  • Parsing "true" and "false" using Boost.Spirit.Lex and Boost.Spirit.Qi

    - by Andrew Ross
    As the first stage of a larger grammar using Boost.Spirit I'm trying to parse "true" and "false" to produce the corresponding bool values, true and false. I'm using Spirit.Lex to tokenize the input and have a working implementation for integer and floating point literals (including those expressed in a relaxed scientific notation), exposing int and float attributes. Token definitions #include <boost/spirit/include/lex_lexertl.hpp> namespace lex = boost::spirit::lex; typedef boost::mpl::vector<int, float, bool> token_value_type; template <typename Lexer> struct basic_literal_tokens : lex::lexer<Lexer> { basic_literal_tokens() { this->self.add_pattern("INT", "[-+]?[0-9]+"); int_literal = "{INT}"; // To be lexed as a float a numeric literal must have a decimal point // or include an exponent, otherwise it will be considered an integer. float_literal = "{INT}(((\\.[0-9]+)([eE]{INT})?)|([eE]{INT}))"; literal_true = "true"; literal_false = "false"; this->self = literal_true | literal_false | float_literal | int_literal; } lex::token_def<int> int_literal; lex::token_def<float> float_literal; lex::token_def<bool> literal_true, literal_false; }; Testing parsing of float literals My real implementation uses Boost.Test, but this is a self-contained example. #include <string> #include <iostream> #include <cmath> #include <cstdlib> #include <limits> bool parse_and_check_float(std::string const & input, float expected) { typedef std::string::const_iterator base_iterator_type; typedef lex::lexertl::token<base_iterator_type, token_value_type > token_type; typedef lex::lexertl::lexer<token_type> lexer_type; basic_literal_tokens<lexer_type> basic_literal_lexer; base_iterator_type input_iter(input.begin()); float actual; bool result = lex::tokenize_and_parse(input_iter, input.end(), basic_literal_lexer, basic_literal_lexer.float_literal, actual); return result && std::abs(expected - actual) < std::numeric_limits<float>::epsilon(); } int main(int argc, char *argv[]) { if (parse_and_check_float("+31.4e-1", 3.14)) { return EXIT_SUCCESS; } else { return EXIT_FAILURE; } } Parsing "true" and "false" My problem is when trying to parse "true" and "false". This is the test code I'm using (after removing the Boost.Test parts): bool parse_and_check_bool(std::string const & input, bool expected) { typedef std::string::const_iterator base_iterator_type; typedef lex::lexertl::token<base_iterator_type, token_value_type > token_type; typedef lex::lexertl::lexer<token_type> lexer_type; basic_literal_tokens<lexer_type> basic_literal_lexer; base_iterator_type input_iter(input.begin()); bool actual; lex::token_def<bool> parser = expected ? basic_literal_lexer.literal_true : basic_literal_lexer.literal_false; bool result = lex::tokenize_and_parse(input_iter, input.end(), basic_literal_lexer, parser, actual); return result && actual == expected; } but compilation fails with: boost/spirit/home/qi/detail/assign_to.hpp: In function ‘void boost::spirit::traits::assign_to(const Iterator&, const Iterator&, Attribute&) [with Iterator = __gnu_cxx::__normal_iterator<const char*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, Attribute = bool]’: boost/spirit/home/lex/lexer/lexertl/token.hpp:434: instantiated from ‘static void boost::spirit::traits::assign_to_attribute_from_value<Attribute, boost::spirit::lex::lexertl::token<Iterator, AttributeTypes, HasState>, void>::call(const boost::spirit::lex::lexertl::token<Iterator, AttributeTypes, HasState>&, Attribute&) [with Attribute = bool, Iterator = __gnu_cxx::__normal_iterator<const char*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, AttributeTypes = boost::mpl::vector<int, float, bool, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na>, HasState = mpl_::bool_<true>]’ ... backtrace of instantiation points .... boost/spirit/home/qi/detail/assign_to.hpp:79: error: no matching function for call to ‘boost::spirit::traits::assign_to_attribute_from_iterators<bool, __gnu_cxx::__normal_iterator<const char*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, void>::call(const __gnu_cxx::__normal_iterator<const char*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >&, const __gnu_cxx::__normal_iterator<const char*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >&, bool&)’ boost/spirit/home/qi/detail/construct.hpp:64: note: candidates are: static void boost::spirit::traits::assign_to_attribute_from_iterators<bool, Iterator, void>::call(const Iterator&, const Iterator&, char&) [with Iterator = __gnu_cxx::__normal_iterator<const char*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >] My interpretation of this is that Spirit.Qi doesn't know how to convert a string to a bool - surely that's not the case? Has anyone else done this before? If so, how?

  • Migrating Ruby Site from EngineYard to Heroku

    - by user410925
    As part of a larger project I've been tasked with migrating some existing Ruby on Rails sites (built with an old version of refinerycms 0.9.6.34, at least that's the version listed in the Gemfile included with the source). I don't normally work with Ruby so I'm at a bit of a loss. The previous developers simply handed over the latest git dump as well as a db dump. I'm working first with trying to get the site up working locally on an Ubuntu 11.10 local machine before pushing up to at test Heroku install. If it's possible to just push directly to Heroku with the files they gave, then I can try that, but it's my understanding I need to get everything working and then use Heroku's tools to deploy. The previous devs said they're using ruby 1.8.7 so in Ubuntu I've done the following: aptitude install ruby1.8 ruby1.8-dev ruby1.8-full aptitude install rubygems1.8 I've restored the database and in the config directory I've made changes to the database.yml to point to the restored database. When I try and run "bundle install" from the root of the extracted source dir I get: Invalid gemspec in [/var/lib/gems/1.8/specifications/mail-2.4.4.gemspec]: invalid date format in specification: "2012-03-14 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/tilt-1.3.3.gemspec]: invalid date format in specification: "2011-08-25 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/mime-types-1.18.gemspec]: invalid date format in specification: "2012-03-21 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/sass-rails-3.2.5.gemspec]: invalid date format in specification: "2012-03-19 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/jquery-rails-2.0.2.gemspec]: invalid date format in specification: "2012-04-03 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/mail-2.4.4.gemspec]: invalid date format in specification: "2012-03-14 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/tilt-1.3.3.gemspec]: invalid date format in specification: "2011-08-25 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/mime-types-1.18.gemspec]: invalid date format in specification: "2012-03-21 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/sass-rails-3.2.5.gemspec]: invalid date format in specification: "2012-03-19 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/jquery-rails-2.0.2.gemspec]: invalid date format in specification: "2012-04-03 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/mail-2.4.4.gemspec]: invalid date format in specification: "2012-03-14 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/tilt-1.3.3.gemspec]: invalid date format in specification: "2011-08-25 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/mime-types-1.18.gemspec]: invalid date format in specification: "2012-03-21 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/sass-rails-3.2.5.gemspec]: invalid date format in specification: "2012-03-19 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/jquery-rails-2.0.2.gemspec]: invalid date format in specification: "2012-04-03 00:00:00.000000000Z" Fetching gem metadata from https://rubygems.org/.......

  • Tracking finger move in order to rotate a triangle : tracking is not perfect

    - by Laurent BERNABE
    I've written a custom view, with the OpenGL_1 technology, in order to let user rotate a red triangle just by dragging it along x axis. (Will give a rotation around Y axis). It works, but there is a bit of latency when dragging from one direction to the other (without releasing the mouse/finger). So it seems that my code is not yet "goal perfect". (I am convinced that no code is perfect in itself). I thought of using a quaternion, but maybe it won't be so usefull : must I really use a Quaternion (or a kind of Matrix) ? I've designed application for Android 4.0.3, but it could fit into Android api 3 (Android 1.5) as well (at least, I think it could). So here is my main layout : activity_main.xml <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <com.laurent_bernabe.android.triangletournant3d.MyOpenGLView android:layout_width="match_parent" android:layout_height="match_parent" /> </LinearLayout> Here is my main activity : MainActivity.java package com.laurent_bernabe.android.triangletournant3d; import android.app.Activity; import android.os.Bundle; import android.support.v4.app.NavUtils; import android.view.Menu; import android.view.MenuItem; public class MainActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.activity_main, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case android.R.id.home: NavUtils.navigateUpFromSameTask(this); return true; } return super.onOptionsItemSelected(item); } } And finally, my OpenGL view MyOpenGLView.java package com.laurent_bernabe.android.triangletournant3d; import java.nio.ByteBuffer; import java.nio.ByteOrder; import java.nio.FloatBuffer; import javax.microedition.khronos.egl.EGLConfig; import javax.microedition.khronos.opengles.GL10; import android.content.Context; import android.graphics.Point; import android.opengl.GLSurfaceView; import android.opengl.GLSurfaceView.Renderer; import android.opengl.GLU; import android.util.AttributeSet; import android.view.MotionEvent; public class MyOpenGLView extends GLSurfaceView implements Renderer { public MyOpenGLView(Context context, AttributeSet attrs) { super(context, attrs); setRenderer(this); } public MyOpenGLView(Context context) { this(context, null); } @Override public boolean onTouchEvent(MotionEvent event) { int actionMasked = event.getActionMasked(); switch(actionMasked){ case MotionEvent.ACTION_DOWN: savedClickLocation = new Point((int) event.getX(), (int) event.getY()); break; case MotionEvent.ACTION_UP: savedClickLocation = null; break; case MotionEvent.ACTION_MOVE: Point newClickLocation = new Point((int) event.getX(), (int) event.getY()); int dx = newClickLocation.x - savedClickLocation.x; angle += Math.toRadians(dx); break; } return true; } @Override public void onDrawFrame(GL10 gl) { gl.glClear(GL10.GL_COLOR_BUFFER_BIT | GL10.GL_DEPTH_BUFFER_BIT); gl.glLoadIdentity(); GLU.gluLookAt(gl, 0f, 0f, 5f, 0f, 0f, 0f, 0f, 1f, 0f ); gl.glRotatef(angle, 0f, 1f, 0f); gl.glColor4f(1f, 0f, 0f, 0f); gl.glVertexPointer(2, GL10.GL_FLOAT, 0, triangleCoordsBuff); gl.glDrawArrays(GL10.GL_TRIANGLES, 0, 3); } @Override public void onSurfaceChanged(GL10 gl, int width, int height) { gl.glViewport(0, 0, width, height); gl.glMatrixMode(GL10.GL_PROJECTION); gl.glLoadIdentity(); GLU.gluPerspective(gl, 60f, (float) width / height, 0.1f, 10f); gl.glMatrixMode(GL10.GL_MODELVIEW); } @Override public void onSurfaceCreated(GL10 gl, EGLConfig config) { gl.glEnable(GL10.GL_DEPTH_TEST); gl.glClearDepthf(1.0f); gl.glEnableClientState(GL10.GL_VERTEX_ARRAY); buildTriangleCoordsBuffer(); } private void buildTriangleCoordsBuffer() { ByteBuffer buffer = ByteBuffer.allocateDirect(4*triangleCoords.length); buffer.order(ByteOrder.nativeOrder()); triangleCoordsBuff = buffer.asFloatBuffer(); triangleCoordsBuff.put(triangleCoords); triangleCoordsBuff.rewind(); } private float [] triangleCoords = {-1f, -1f, +1f, -1f, +1f, +1f}; private FloatBuffer triangleCoordsBuff; private float angle = 0f; private Point savedClickLocation; } I don't think I really have to give you my manifest file. But I can if you think it is necessary. I've just tested on Emulator, not on real device. So, how can improve the reactivity ? Thanks in advance.

  • Spring MVC configuration problems

    - by Smek
    i have some problems with configuring Spring MVC. I made a maven multi module project with the following modules: /api /domain /repositories /webapp I like to share the domain and the repositories between the api and the webapp (both web projects). First i want to configure the webapp to use the repositories module so i added the dependencies in the xml file like this: <dependency> <groupId>${project.groupId}</groupId> <artifactId>domain</artifactId> <version>1.0-SNAPSHOT</version> </dependency> <dependency> <groupId>${project.groupId}</groupId> <artifactId>repositories</artifactId> <version>1.0-SNAPSHOT</version> </dependency> And my controller in the webapp module looks like this: package com.mywebapp.webapp; import com.mywebapp.domain.Person; import com.mywebapp.repositories.services.PersonService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.context.annotation.ComponentScan; import org.springframework.context.annotation.Configuration; import org.springframework.stereotype.Controller; import org.springframework.ui.ModelMap; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; @Controller @RequestMapping("/") @Configuration @ComponentScan("com.mywebapp.repositories") public class PersonController { @Autowired PersonService personservice; @RequestMapping(method = RequestMethod.GET) public String printWelcome(ModelMap model) { Person p = new Person(); p.age = 23; p.firstName = "John"; p.lastName = "Doe"; personservice.createNewPerson(p); model.addAttribute("message", "Hello world!"); return "index"; } } In my webapp module i try to load configuration files in my web.xml like this: <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:/META-INF/persistence-context.xml, classpath:/META-INF/service-context.xml</param-value> </context-param> These files cannot be found so i get the following error: org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from class path resource [META-INF/persistence-context.xml]; nested exception is java.io.FileNotFoundException: class path resource [META-INF/persistence-context.xml] cannot be opened because it does not exist These files are in the repositories module so my first question is how can i make Spring to find these files? I also have trouble Autowiring the PersonService to my Controller class did i forget to configure something in my XML? Here is the error message: [INFO] [talledLocalContainer] SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener [INFO] [talledLocalContainer] org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'personServiceImpl': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.mywebapp.repositories.repository.PersonRepository com.mywebapp.repositories.services.PersonServiceImpl.personRepository; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.mywebapp.repositories.repository.PersonRepository] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

  • Changing name attr of cloned input element in jQuery doesn't work in IE6/7

    - by BalusC
    This SSCCE says it all: <!doctype html> <html lang="en"> <head> <title>Test</title> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script> <script type="text/javascript"> $(document).ready(function() { $('#add').click(function() { var ul = $('#ul'); var liclone = ul.find('li:last').clone(true); var input = liclone.find('input'); input.attr('name', input.attr('name').replace(/(foo\[)(\d+)(\])/, function(f, p1, p2, p3) { return p1 + (parseInt(p2) + 1) + p3; })); liclone.appendTo(ul); $('#showsource').text(ul.html()); }); }); </script> </head> <body> <ul id="ul"> <li><input type="text" name="foo[0]"></li> </ul> <button id="add">Add</button> <pre id="showsource"></pre> </body> </html> Copy'n'paste'n'run it, click the Add button several times. On every click you should see the HTML code of the <ul> to show up in the <pre id="showsource"> and the expected code should roughly be: <li><input name="foo[0]" type="text"></li> <li><input name="foo[1]" type="text"></li> <li><input name="foo[2]" type="text"></li> <li><input name="foo[3]" type="text"></li> This works as expected in FF, Chrome, Safari, Opera and IE8. However, IE6/7 fails in changing the name attribute and produces like: <li><input name="foo[0]" type="text"> <li><input name="foo[0]" type="text"> <li><input name="foo[0]" type="text"> <li><input name="foo[0]" type="text"></li> I googled a bit and found this very similar problem, he fixed it and posted a code snippet how it should have look like. Unfortunately this is exactly what I already have done, so I suspect that he was only testing in IE8, not in IE6/7. Other than that particular topic Google didn't reveal much. Any insights? Or do I really have to grab back to document.createElement? Note: I know that I can use just the same name for each input element and retrieve them as an array, but the above is just a basic example, in real I really need to have the name attribute changed, because it not only contains the index, but also other information such as parentindex, ordering, etc. It's been used to add/rearrange/remove (sub)menu items. Edit: this is related to this bug, The jQuery (I'm using 1.3.2) does thus not seem to create inputs that way? The following does just work: $('#add').click(function() { var ul = $('#ul'); var liclone = ul.find('li:last').clone(true); var oldinput = liclone.find('input'); var name = oldinput.attr('name').replace(/(foo\[)(\d+)(\])/, function(f, p1, p2, p3) { return p1 + (parseInt(p2) + 1) + p3; }); var newinput = $('<input name="' + name + '">'); oldinput.replaceWith(newinput); liclone.appendTo(ul); $('#showsource').text(ul.html()); }); But I can't imagine that I am the only one who encountered this problem with jQuery. Even a simple $('<input>').attr('name', 'foo') doesn't work in IE6/7. Isn't jQuery as being a crossbrowser library supposed to cover this particular issue under the hoods?

  • What add-in/workbench framework is the best .NET alternative to Eclipse RCP?

    - by Winston Fassett
    I'm looking for a plugin-based application framework that is comparable to the Eclipse Plugin Framework, which to my simple mind consists of: a core plugin management framework (Equinox / OSGI), which provides the ability to declare extension endpoints and then discover and load plugins that service those endpoints. (this is different than Dependency Injection, but admittedly the difference is subtle - configuration is highly de-centralized, there are versioning concerns, it might involve an online plugin repository, and most importantly to me, it should be easy for the user to add plugins without needing to know anything about the underlying architecture / config files) many layers of plugins that provide a basic workbench shell with concurrency support, commands, preference sheets, menus, toolbars, key bindings, etc. That is just scratching the surface of the RCP, which itself is meant to serve as the foundation of your application, which you build by writing / assembling even more plugins. Here's what I've gleaned from the internet in the past couple of days... As far as I can tell, there is nothing in the .NET world that remotely approaches the robustness and maturity of the Eclipse RCP for Java but there are several contenders that do either #1 or #2 pretty well. (I should also mention that I have not made a final decision on WinForms vs WPF, so I'm also trying to understand the level of UI coupling in any candidate framework. I'm also wondering about platform coupling and source code licensing) I must say that the open-source stuff is generally less-documented but easier to understand, while the MS stuff typically has more documentation but is less accessible, so that with many of the MS technologies, I'm left wondering what they actually do, in a practical sense. These are the libraries I have found: SharpDevelop The first thing I looked at was SharpDevelop, which does both #1 and also #2 in a basic way (no insult to SharpDevelop, which is admirable - I just mean more basic than Eclipse RCP). However, SharpDevelop is an application more than a framework, and there are basic assumptions and limitations there (i.e. being somewhat coupled to WinForms). Still, there are some articles on CodeProject explaining how to use it as the foundation for an application. System.Addins It appears that System.Addins is meant to provide a robust add-in loading framework, with some sophisticated options for loading assemblies with varying levels of trusts and even running the out of process. It appears to be primarily code-based, and pretty code-heavy, with lots of assemblies that serve to insulate against versioning issues., using Guidance Automation to generate a good deal of code. So far I haven't found many System.AddIns articles that illustrate how it could be used to build something like an Eclipse RCP, and many people seem to be wringing their hands about its complexity. Mono.Addins It appears that Mono.Addins was influenced by System.Addins, SharpDevelop, and MonoDevelop. It seems to provide the basics from System.Addins, with less sophisticated options for plugin loading, but more simplicity, with attribute-based registration, XML manifests, and the infrastructure for online plugin repositories. It has a pretty good FAQ and documentation, as well as a fairly robust set of examples that really help paint a picture of how to develop an architecture like that of SharpDevelop or Eclipse. The examples use GTK for UI, but the framework itself is not coupled to GTK. So it appears to do #1 (add-in loading) pretty well and points the way to #2 (workbench framework). It appears that Mono.Addins was derived from MonoDevelop, but I haven't actually looked at whether MonoDevelop provides a good core workbench framework. Managed Extensibility Framework This is what everyone's talking about at the moment, and it's slowly getting clearer what it does, but I'm still pretty fuzzy, even after reading several posts on SO. The official word is that it "can live side-by-side" with System.Addins. However, it doesn't reference it and it appears to reproduce some of its functionality. It seems to me, then, that it is a simpler, more accessible alternative to System.Addins. It appears to be more like Mono.Addins in that it provides attribute-based wiring. It provides "catalogs" that can be attribute-based or directory-based. It does not seem to provide any XML or manifest-based wiring. So far I haven't found much documentation and the examples seem to be kind of "magical" and more reminiscent of attribute-based DI, despite the clarifications that MEF is not a DI container. Its license just got opened up, but it does reference WindowsBase -- not sure if that means it's coupled to Windows. Acropolis I'm not sure what this is. Is it MEF, or something that is still coming? Composite Application Blocks There are WPF and Winforms Composite Application blocks that seem to provide much more of a workbench framework. I have very little experience with these but they appear to rely on Guidance Automation quite a bit are obviously coupled with the UI layers. There are a few examples of combining MEF with these application blocks. I've done the best I could to answer my own question here, but I'm really only scratching the surface, and I don't have experience with any of these frameworks. Hopefully some of you can add more detail about the frameworks you have experience with. It would be great if we could end up with some sort of comparison matrix.

  • Wisdom of merging 100s of Oracle instances into one instance

    - by hoytster
    Our application runs on the web, is mostly an inquiry tool, does some transactions. We host the Oracle database. The app has always had a different instance of Oracle for each customer. A customer is a company which pays us to provide our service to the company's employees, typically 10,000-25,000 employees per customer. We do a major release every few years, and migrating to that new release is challenging: we might have a team at the customer site for a couple weeks, explaining new functionality and setting up the driving data to suit that customer. We're considering going multi-client, putting all our customers into a single shared Oracle 11g instance on a big honkin' Windows Server 2008 server -- in order to reduce costs. I'm wondering if that's advisable. There are some advantages to having separate instances for each customer. Tell me if these are bogus, please. In my rough guess about decreasing importance: Our customers MyCorp and YourCo can be migrated separately when breaking changes are made to the schema. (With multi-client, we'd be migrating 300+ customers overnight!?!) MyCorp's data can be easily backed up and (!!!) restored, without affecting other customers. MyCorp's data is securely separated from their competitor YourCo's data, without depending on developers to get the code right and/or DBAs getting the configuration right. Performance is better because the database is smaller (5,000 vs 2,000,000 rows in ~50 tables). If MyCorp's offices are (mostly) in just one region, then the MyCorp's instance can be geographically co-located there, so network lag doesn't hurt performance. We can provide better service to global clients, for the same reason. In MyCorp wants to take their database in-house, then we can easily export their instance, to get MyCorp their data. Load-balancing is easier because instances can be placed on different servers (this is with a web farm). When a DEV or QA instance is needed, it's easier to clone the real instance and anonymize the data, because there's much less data. Because they're small enough, developers can have their own instance running locally, so they can work on code while waiting at the airport and while in-flight, without fighting VPN hassles. Q1: What are other advantages of separate instances? We are contemplating changing the database schema and merging all of our customers into one Oracle instance, running on one hefty server. Here are advantages of the multi-client instance approach, most important first (my WAG). Please snipe if these are bogus: Less work for the DBAs, since they only need to maintain one instance instead of hundreds. Less DBA work translates to cheaper, our main motive for this change. With just one instance, the DBAs can do a better job of optimizing performance. They'll have time to add appropriate indexes and review our SQL. It will be easier for developers to debug & enhance the application, because there is only one schema and one app (there might be dozens of schema versions if there are hundreds of instances, with a different version of the app for each version of the schema). This reduces costs too. The alternative is having to start every debug session with (1) What version is this customer running and (2) Let's struggle to recreate the corresponding development environment, code and database. (We need a Virtual Machine that includes the code AND database instance for each patch and release!) Licensing Oracle is cheaper because it's priced per server irrespective of heft (or something -- I don't know anything about the subject). The database becomes a viable persistent store for web session data, because there is just one instance. Some database operations are easier with one multi-client instance, like finding a participant when they're hazy about which customer they (or their spouse, maybe) works for: all the names are in one table. Reporting across customers is straightforward. Q2: What are other advantages of having multiple clients in one instance? Q3: Which approach do you think is better (why)? Instance per customer, or all customers in one instance? I'm concerned that having one multi-client instance makes migration near-impossible, and that's a deal killer... ... unless there is a compromise solution like having two multi-client instances, the old and the new. In that case case, we would design cross-instance solutions for finding participants, reporting, etc. so customers could go from one multi-client instance to the next without anything breaking. THANKS SO MUCH for your collective advice! This issue is beyond me -- but not beyond the collective you. :) Hoytster
