  • MS VC++ 6 class wizard

    - by Shane MacLaughlin
    Ok, I'm developing an application that has been in pretty much continous development over the last 16 years, from C in DOS, through various flavours of C++ and now is largely based around C++ with MFC and StingRay GUIs and various other SDKs. While I use VS 2005 for the release builds, I still use MSVC 6 for much of the GUI building, simply because ClassWizard is so much quicker in this environment than the weak equivalent tools that followed. Note that I am using ClassWizard to automatically generate code for my own user defined types (see Custom DDXs) and I like to add a lot of member variables and methods in one go. Creating them one at a time as per later versions of Visual Studio for me is a big backward step. At the same time, working with multiple IDEs is also a pain. My question is in two parts; Is there any way of getting ClassWizard to work is VS 2005 or VS 2008? Is there any drop in replacement, or alternative IDE, that provides similar levels of productivty for old C++ hacks such as myself?

  • Preloading images in HTML, is there a more modern way?

    - by John
    I have an image loaded by JS on a mouse event. It's a fairly big image so I want to make sure it gets pre-loaded. I reemmber some old techniques from years ago and found this example: <SCRIPT LANGUAGE = JAVASCRIPT> if (document.images) { img1 = new Image(); img2 = new Image(); img1.src = "imageName1.gif"; img2.src = "imageName2.gif" } </SCRIPT> I wondered if this is still good/relevant, or maybe browsers automatically detect unused images and preload them anyway? Note my page has to support IE6, so I might still need older techniques anyway, but I'm still interested if more modern browsers have a better way?

  • How do i parse the new wow RSS feed? (LINQ to XML)

    - by Sunzaru Sven
    The link i want to parse is here. I'm looking to parse it in "real time" so that as things happen i can send myself messages/tweets and what not. I plan on having each element of the XML from the feed as an item of a class/struct. I'm really looking for LINQ to XML examples, and a good book. I've seen other LINQ to XML articles out there, but i'm just not grasping how they work. Old SQL minds are hard to break perhaps... /shrug.

  • How to write a value validation method for core data?

    - by mystify
    The docs say: you should implement methods of the form validate:error:, as defined by the NSKeyValueCoding protocol so lets say I have an attribute which is an int: friendAge I want to make sure that any friend may not be younger than 30. So how would I make that validation method? -validateFriendAge:error: What am I gonna do in there, exactly? And what shall I do with that NSError I get passed? I think it has an dictionary where I can return a humanly readable string in an arbitrary language (i.e. the one that's used currently), so I can output a reasonable error like: "Friend is not old enough"... how to do that?

  • NSTableView doesn't populate with array objects until a new object is added via the controller

    - by Luke
    I have an NSTableView and an array controller set up as shown here, using cocoa bindings: https://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/TableView/PopulatingViewTablesWithBindings/PopulatingView-TablesWithBindings.html#//apple_ref/doc/uid/10000026i-CH13-SW3 In my app delegate during applicationDidFinishLaunching I have the following snippet in here, initialising the array and filling it with objects array = [[NSMutableArray alloc] init]; SomeObject* foo = [[Object alloc] init]; foo.text = @"sup"; [array addObject:foo]; //Repeat this a few times However, when I build the app and run it I end up with an empty table. However, if I bind a button to the array controller's add: input and click it during runtime (this adds a new object to the array and table) then the table will show the new object first, with the objects added during applicationDidFinishLaunching following it. Why does this happen? And is there a way to make my table populate without having to add an element first?

  • How to use pointer from COM object on C#?

    - by Jaeh
    All. I'm trying to use my old dll file on .net project. So I converted this unmanaged COM object to managed one by using [tlbimp.exe] util from Windows SDK. However, one method returns a Object as a return value, but whenever I try to use it, my program generates an error. The weird thing is below: //Object[] item = s.GetObjects(); //this generates an type error Object item = s.GetObjects(); //this works okay System.WriteLine(items); //prints System.Object[] rather than System.Object. It seems like it returns a pointer which contains an object array. Isn't it ? Please anyone tell me how to handle this, and is there any documentation for this issue ?

  • Having trouble parsing itunes affiliate xml...

    - by MKDev
    Hi, I am trying to parse an itunes affiliate xml link purely for practise, using NSXMLParser but the link will not parse. The itunes affiliate xml link is this: http://itunes.apple.com/au/rss/topsongs/limit=50/genre=20/xml?partnerId=2003&TD_PARAM=http%3A%2F%2Fclkuk.tradedoubler.com%2Fclick%3Fp%3D23708%26a%3D1904172%26url%3D. it works perfectly in safari on my mac. The normal itunes link I tried parsing: http://itunes.apple.com/%@/rss/%@/limit=50/genre=20/xml works perfectly with the NSXMLParser. Can anyone tell me why this is happening? Thanks in advanced.

  • FKs on all tables for status colunm

    - by Jonarch
    I have a colunm "Status" in every table in my DB. The purpose of it is to show if the given row is in use or if it has been deactivated. So values can be (0=deactive and 1= active). Two ways I see this: I can have enums or I am thinking if it is better to keep this colunm as a FK which references the main system data dictionary table which has all the codes used on the system. (website) The benefit is every table, every row can then be centralized through this FK. So if i ever want to check all rows which are deactive on my system i can from this table as all th child tables will have like status = ID 233, where 233 = deactive in the data dictionary table. Any benefit or should i stick with the old way of enums?. Also I am thinking if i need one more status for deleted or is that same as deactivated?

  • Git svn - no changes, no branches (except master), rebase/info is not working

    - by ex3v
    I know that similar questions were asked before, but I think my is a little bit different, so please don't point me to existing threads. I'm migrating our old svn repo to git. I did git svn clone path --authors-file abc.txt and everything seemend legit to me. Then I did git remote add origin xyz and git push --all origin and it also worked. I created this repo as test one, with only me having access to both local repo and origin. No changes were made in project held on this repo, nothing to commit, no pushing and so on. There is also only one branch, because someone initialized svn years ago without creating proper folder structure (branches, trunk, tags). Meanwhile someone pushed their work to svn, so I tried to git svn fetch (which worked), and git svn rebase which didn't, giving me error: Unable to determine upstream SVN information from working tree history Is there any reason why git svn decided to stop working?

  • How do I get User.message_set messages to show up for the built in test client?

    - by Conley Owens
    I'm aware that the old Django messages framework is deprecated, but I still would like to know the answer to this. When I go to a certain url to my broswer, a message is created, I am redirected to a different page, and I see the message correctly displayed by my template. When the test client goes to the same url, the message is created, it gets a redirect, and after following the redirect there are no messages. However, no messages appear in the response (the response gotten from following the redirect). Why not?

  • Setting enum values to 4-byte strings - why?

    - by psychotik
    I saw code similar to this in the Mac OS SDK: enum { kAudioFileStreamProperty_ReadyToProducePackets = 'redy', kAudioFileStreamProperty_FileFormat = 'ffmt', kAudioFileStreamProperty_DataFormat = 'dfmt', kAudioFileStreamProperty_FormatList = 'flst', kAudioFileStreamProperty_MagicCookieData = 'mgic', kAudioFileStreamProperty_AudioDataByteCount = 'bcnt', kAudioFileStreamProperty_AudioDataPacketCount = 'pcnt', kAudioFileStreamProperty_MaximumPacketSize = 'psze', kAudioFileStreamProperty_DataOffset = 'doff', kAudioFileStreamProperty_ChannelLayout = 'cmap', kAudioFileStreamProperty_PacketToFrame = 'pkfr', kAudioFileStreamProperty_FrameToPacket = 'frpk', kAudioFileStreamProperty_PacketToByte = 'pkby', kAudioFileStreamProperty_ByteToPacket = 'bypk', kAudioFileStreamProperty_PacketTableInfo = 'pnfo', kAudioFileStreamProperty_PacketSizeUpperBound = 'pkub', kAudioFileStreamProperty_AverageBytesPerPacket = 'abpp', kAudioFileStreamProperty_BitRate = 'brat' }; It's the first time I've seen this - I assume the compiler assigns the 32-bit integer equivalent of the strings to the enum values. I cannot think of a single good reason why this might be preferred over using simple integers. It looks hideous in a debugger (how do you tell which of these values corresponds to 1919247481?) and makes debugging just hard in general. So, is there any reason where assigning such strings to enum values actually makes sense.

  • Why does SQLite say it can't read SQL from a file?

    - by Gavin
    Hi all. I have a bunch of SQL in a file, which creates the tables and so forth. The problem is that the .read command simply returns "can't open xxx" when I try to execute it. I've set the permissions to everybody read/write, but that didn't help. I can cat the file from the command line and see it fine. This is under Mac OS 10.6.3. Anybody have any idea here? Thanks!

  • SSRS and cached reports

    - by Tabloo Quijico
    Hi, I'm opening an SSRS2008 report using the http://server/reportserver/... syntax, outputting directly a PDF copy. This report has several parameters. The problem is that, despite making changes to the report, and clearing the browser's temporary files cache.. if I request the same report (i.e. same parameters) - the old report is returned. In the report execution properties, I have "Always run this report with the most recent data" and "Do not cache temporary copies of this report" selected. It's not just a case of caching data, but the entire report (including formatting, e.g. I deleted a page from the report yet it was still being shown...) and as I haven't specifically chosen to perform any caching I'm a little concerned and clearly don't fully understand what's going on! Any tips?

  • Should I still use querystrings for page number, etc, when using ASP.NET 4 URL Routing?

    - by Scott
    I am switching from Intelligencia's UrlRewriter to the new web forms routing in ASP.NET 4.0. I have it working great for basic pages, however, in my e-commerce site, when browsing category pages, I previously used querystrings that were built into my pager control to control paging. An old url (with UrlRewriting) would be: http://www.mysite.com/Category/Arts-and-Crafts_17 I now have a MapPageRoute defined in global.asax as: routes.MapPageRoute("category-browse", "Category/{name}_{id}", ~/CategoryPage.aspx"); This works great. Now, somebody clicks to go to page 2. Previously I would have just tacked on ?page=2 as the querystring. Now, How do I handle this using web forms routing? I know I can do something like: http://www.mysite.com/Category/Arts-and-Crafts_17/page/2 But in addition to page, I can have filters, age ranges, gender, etc. Should I just keep defining routes that handle these variables, or should I continue using querystrings and can I define a route that allows me to use my querstrings like before?

  • What is the best solution to replace a new memory allocator in an existing code?

    - by O. Askari
    During the last few days I've gained some information about memory allocators other than the standard malloc(). There are some implementations that seem to be much better than malloc() for applications with many threads. For example it seems that tcmalloc and ptmalloc have better performance. I have a C++ application that uses both malloc and new operators in many places. I thought replacing them with something like ptmalloc may improve its performance. But I wonder how does the new operator act when used in C++ application that runs on Linux? Does it use the standard behavior of malloc or something else? What is the best way to replace the new memory allocator with the old one in the code? Is there any way to override the behavior or new and malloc or do I need to replace all the calls to them one by one?

  • how can I "force" a branch upon the trunk, in the case I can't "reintegrate"?

    - by davka
    We created a branch from the trunk on which a major refactoring was done. Meanwhile, the trunk advanced a few revisions with some fixes. We don't want these changes on the branch, so we don't want to "catch-up" merge the trunk to the branch, because we don't want to mix the old and new code. But without this I can't reintegrate the branch back to the trunk. Is there a way to impose the branch on the trunk "as-is"? (an idea I considered is to undo ("reverse-merge") the trunk back to the revision where the branch started, and then it is safe to merge it on branch - nothing should happen. Then I can reintegrate. What do you think?) thanks!

  • laravel multiple where clauses within a loop

    - by user1424508
    Pretty much I want the query to select all records of users that are 25 years old AND are either between 150-170cm OR 190-200cm. I have this query written down below. However the problem is it keeps getting 25 year olds OR people who are 190-200cm instead of 25 year olds that are 150-170 OR 25 year olds that 190-200cm tall. How can I fix this? thanks $heightarray=array(array(150,170),array(190,200)); $user->where('age',25); for($i=0;$i<count($heightarray);i++){ if($i==0){ $user->whereBetween('height',$heightarray[$i]) }else{ $user->orWhereBetween('height',$heightarray[$i]) } } $user->get(); Edit: I tried advanced wheres (http://laravel.com/docs/queries#advanced-wheres) and it doesn't work for me as I cannot pass the $heightarray parameter into the closure. from laravel documentation DB::table('users') ->where('name', '=', 'John') ->orWhere(function($query) { $query->where('votes', '>', 100) ->where('title', '<>', 'Admin'); }) ->get();

  • iPhone framework paths?

    - by user158103
    I recently moved my projects to a new mac, along with a newer version of Xcode. When i opened my project i noticed that some files were red. So i remapped them by setting the path (by project path) and then providing the proper path location. Now my problem is that the frameworks that i have are red, and i cant find their location! I did set the framework paths to be "relative to current SDK" however. Can anybody help me get my frameworks mapped correctly? The frameworks im using are: - QuartzCore.framework - libsqlite3.0.dylib - UIKit.framework - Foundation.frameowrk - CoreGraphics.framework The XCode version is 3.1.4 (the only one installed). The iPhone app was originally created using a prior version of Xcode (i dont remember which version).

  • How to write a program that mimics Fiddler by using tcpdump or from scratch?

    - by ????
    When Fiddler is not on Mac OS X or Ubuntu, and if we don't install/use Wireshark or any other more heavy duty tools, what is a way to use tcpdump so that 1) It can print out GET /foo/bar HTTP/1.1 [request content in RAW text] [response content in RAW text] POST /foo/... HTTP/1.1 this should be able to be done by tcpdump or by using tcpdump in a short shell script or Ruby / Python / Perl script. 2) Actually, it can be neat if a script can output HTML, with GET /foo/bar HTTP/1.1 POST /foo/... HTTP/1.1 on the page, for any browser to display, and then when clicked on any of those lines, it will expand to show the RAW content like (1) above does. Click again and it will hide the details. The expansion UI can be done using jQuery or any JS library. The script may be short... possibly less than 20 lines? Does anybody know how to do it either for (1) or (2)?

  • Form variable does not refresh with ajax call

    I'm building a simple email sending form and wanted to make it with ajax. The form submits correctly the first time but if you make any subsequent changes to the text in the form and then submit again then jquery does not pick up on the changes and posts the old data. Whats going on? <script type="text/javascript"> var $j = jQuery.noConflict(); $j(document).ready(function() { var submit_url = "mail_submit.php"; var send_email = $j("#sendemail"); send_email.click(function() { var form = $j("#post"); $j.post(submit_url, form.serialize(), function(data) { alert(data); }); }); });

  • info about intel Cos embedded i86 os

    - by Tim Williscroft
    I've got some old Intel printer (Etherexpress XL ) print servers and they seem to be running an Intel OS called Cos aka Intel Client Os i86 I've found out that much just looking in the update files from Intel. It was at least partly written in C. How do I make a custom software image Intel Cos's boot loader will understand ? I know a host PC xmodem's the image to the client device, and I was wondering if anyone had already either reverse-engineered this or had original info ? or is my only recousre to reverse engineer the update file format ?

  • linq with Include and criteria

    - by JMarsch
    How would I translate this into LINQ? Say I have A parent table (Say, customers), and child (addresses). I want to return all of the Parents who have addresses in California, and just the california address. (but I want to do it in LINQ and get an object graph of Entity objects) Here's the old fashioned way: SELECT c.blah, a.blah FROM Customer c INNER JOIN Address a on c.CustomerId = a.CustomerId where a.State = 'CA' The problem I'm having with LINQ is that i need an object graph of concrete Entity types (and it can't be lazy loaded. Here's what I've tried so far: // this one doesn't filter the addresses -- I get the right customers, but I get all of their addresses, and not just the CA address object. from c in Customer.Include(c = c.Addresses) where c.Addresses.Any(a = a.State == "CA") select c // this one seems to work, but the Addresses collection on Customers is always null from c in Customer.Include(c = c.Addresses) from a in c.Addresses where a.State == "CA" select c; Any ideas?

  • Creating many native GUI frontends for a cross-platform application

    - by Hugh Young
    I've been away from GUI programming for quite some time so please pardon my ignorance. I would like to attempt the following: Write a Mac OSX app but still be able to port to Win/Linux (i.e. C++ core with Obj-C GUI) Avoid Qt/other toolkits on OSX (i.e. talk to Cocoa directly - I feel that many Qt apps I use stick out like sore thumbs compared to the rest of my system) Not as important, but it would be nice to avoid Visual Studio if it means I can have the freedom to use newer C++ features even on Windows if they help create better code. I believe this configuration might get me what I'm looking for: Core C++ Static Library OSX GUI (Cocoa) Windows GUI (Qt+MinGW?) OR (no new C++ features, Visual Studio + ManagedC++/C#/????) Linux GUI (Qt) Once again, sorry for my ignorance but is this possible? Is this sane? Are there any real-world open source examples accomplish something like this?

  • C# .NET 2.0 components

    - by Ervin
    How can I check what objects, tools, variables, anything... are used from .NET 2.0 in a C# application. How can I get a C# application run without .NET 2.0 ? UPDATE: sorry, I didn't clarify enought. Here's my situation: I have developed a pretty simple application in C#: embeded browser which displayes static webpages with an option of searching inside of these html pages. I'm using simple textbox, buttons components for this. The application will be distribuited for people wich have very old PCs, even with windows 95. I would like the app to be runable on it, or at least on win 98, without telling the people to install .NET 2.0, as the users don;t really have PC usage skills :) .
