  • API Failure Sqlite

    - by Joseph Anderson
    I ran the Windows 8 App Certification Kit on my app and it says it will fail because of Sqllite. Am I referencing code incorrectly or can I ignore this problem?

  • Content Management System Where the Content needs to reside

    - by lee
    Hi, We are developing a Online Ordering Website and we are planning to be completely flexible in the sense Layout can be changed, Color, Font , and in a page a component(div) can be added. In this case whether we need to store all our View Code for example <div id="MenuContent"> <div> <h4> Your Order</h4> <hr /> <%if (Model != null) { %> <table width="100%"> <thead> <tr> <th> Item </th> <th> Quantity </th> <th> Price </th> <th> Remove </th> <th> Total </th> </tr> </thead> ...... in the database or we can just store the div id and based on that load a view which is avalaible in the file system. Any Pointers is greatly appreciated.

  • SWIG: Python list to uint32_t *?

    - by Lee Crabtree
    I'm trying to work with a Python module that was generated by SWIG. There's a C++ class defined that works like this (simplified): namespace Foo { class Thing { public: Thing(); ~Thing(); bool DoSomething(uint32_t x, uint32_t y, uint32_t z, uint32_t *buffer); }; }; When I try to call it from Python, I get an error about the last argument needing to be of type 'uint32_t*'. Normal Python integers work just fine for the other arguments, so I can't understand why a list of ints wouldn't work for the buffer. Any suggestions?

  • How to use htaccess to rewrite url to html anchor tag (#)

    - by Lee L
    Hi - I have a situation where I want to take the following URL: /1/john and have it redirect using Apache's htaccess file to go to /page.php?id=1&name=john#john so that it goes to an html anchor with the name of john. I've found a lot of reference to escaping special characters, and to adding the [NE] flag so that the redirect ignores the # sign, but these don't work. For example, adding [NE,R] means that the URL just appears in the browser address as the original: http://mysite.com/page.php?id=1&name=john#john. Any help would be appreciated.

  • Is it possible to share a C struct in shared memory between apps compiled with different compilers?

    - by Joseph Garvin
    I realize that in general the C and C++ standards gives compiler writers a lot of latitude. But in particular it guarantees that POD types like C struct members have to be laid out in memory the same order that they're listed in the structs definition, and most compilers provide extensions letting you fix the alignment of members. So if you had a header that defined a struct and manually specified the alignment of its members, then compiled two apps with different compilers using the header, shouldn't one app be able to write an instance of the struct into shared memory and the other app be able to read it without errors? I am assuming though that the size of the types contained is consistent across two compilers on the same architecture (it has to be the same platform already since we're talking about shared memory). I realize that this is not always true for some types (e.g. long vs. long long in GCC and MSVC 64-bit) but nowadays there are uint16_t, uint32_t, etc. types, and float and double are specified by IEEE standards.

  • Display Special Characters (Korean Letters) in RichTextBox

    - by Peter Lee
    Hi, My question might be a little bit confusing, but I think it's still worth of paying some attention. Basically I'm designing a program to display all printable Unicode characters in a RichTextBox. I'm using VC# 2010 Express Edition. However, the RichTextBox has a critical problem: some special characters cannot be displayed correctly. For example, some Korean Characters (??????????????????????????????), can be displayed correctly in Microsoft Word. After I copy to the RichTextBox, the characters cannot be displayed correctly. However, when I copy back to Microsoft Word, it can be displayed correctly. Therefore, it's a display problem (the characters themselves are correct). I guess it might be a font problem. Some related property info: RichTextBox.Font.GdiChaSet RichTextBox.Font How can I solve it? So that all printable Unicode characters can be displayed correctly (using different fonts for different CharSets are acceptable). Actually, I need further assistance about removing all formatting when pasting rtbxFileContent.Paste(DataFormats.GetFormat(DataFormats.Text)); // DataFormats.UnicodeText I still need to have all printable characters to be displayed correctly, but without any formatting (except font). Thanks. Hope I made myself understood.

  • Javascript Post Request like a Form Submit

    - by Joseph Holsten
    I'm trying to direct a browser to a different page. If I wanted a GET request, I might say document.location.href = 'http://example.com/q=a'; But the resource I'm trying to access won't respond properly unless I use a POST request. If this were not dynamically generated, I might use the HTML <form action="http://example.com/" method="POST"> <input type="hidden" name="q" value="a"> </form> Then I would just submit the form from the DOM. But really I would like JavaScript that allows me to say post_to_url('http://example.com/', {'q':'a'}); What's the best cross browser implementation? Edit I'm sorry I was not clear. I need a solution that changes the location of the browser, just like submitting a form. If this is possible with XMLHTTPRequest, it is not obvious. And this should not be asynchronous, nor use XML, so AJAX is not the answer.

  • Java error: Bad version number in .class file error when trying to run Cassandra on OS X

This does not work for my situation because I want pushes (and pulls if possible) to be secure. All the tutorials I've been able to find also use push_ssl=False. Can anyone give me pointers on how to set up ssl/security for Mercurial? Thanks.

  • Where to Store the Protection Trial Info for Software Protection Purpose

    - by Peter Lee
    It might be duplicate with other questions, but I swear that I googled a lot and search at StackOverflow.com a lot, and I cannot find the answer to my question: In a C#.Net application, where to store the protection trial info, such as Expiration Date, Number of Used Times? I understand that, all kinds of Software Protection strategies can be cracked by a sophiscated hacker (because they can almost always get around the expiration checking step). But what I'm now going to do is just to protect it in a reasonable manner that a "common"/"advanced" user cannot screw it up. OK, in order to proof that I have googled and searched a lot at StackOverflow.com, I'm listing all the possible strategies I got: 1. Registry Entry First, some users might not have the access to even read the Registry table. Second, if we put the Protection Trial Info in a Registry Entry, the user can always find it out where it is by comparing the differences before and after the software installation. They can just simply change it. OK, you might say that we should encrypt the Protection Trial Info, yes we can do that. But what if the user just change their system date before installing? OK, you might say that we should also put a last-used date, if something is wrong, the last-used date could work as a protection guide. But what if the user just uninstall the software and delete all Registry Entries related to this software, and then reinstall the software? I have no idea on how to deal with this. Please help. A Plain File First, there are some places to put the plain file: 2.a) a simple XML file under software installation path 2.b) configuration file Again, the user can just uninstall the software and remove these plain file(s), and reinstall the software. - The Software Itself If we put the protection trial info (Expiration Date, we cannot put Number of Used Times) in the software itself, it is still susceptible to the cases I mentioned above. Furthermore, it's not even cool to do so. - A Trial Product-Key It works like a licensing process, that is, we put the Trial info into an RSA-signed string. However, it requires too many steps for a user to have a try of using the software (they might lose patience): 4.a) The user downloads the software; 4.b) The user sends an email to request a Trial Product-Key by providing user name (or email) or hardware info; 4.c) The server receives the request, RSA-signs it and send back to the user; 4.d) The user can now use it under the condition of (Expiration Date & Number of Used Times). Now, the server has a record of the user's username or hardware info, so the user will be rejected to request a second trial. Is it legal to collection hardware info? In a word, the user has to do one more extra step (request a Trial Product Key) just for having a try of using the software, which is not cool (thinking myself as a user). NOTE: This question is not about the Licensing, instead, it's about where to store the TRIAL info. After the trial expires, the user should ask for a license (CD-Key/Product-Key). I'm going to use RSA signature (bound to User Hardware)

  • UpdatePanel doesn't do partial-page update, and IsInAsyncPostBack is always false

    - by Joseph Anderson
    I'm attempting to use an UpdatePanel, but can't get partial-page updates to work. When I look at the ScriptManager's IsInAsyncPostBack property, it's always false. Here's a page that reproduces the issue. It has a ScriptManager, an UpdatePanel, a LinkButton within the update panel, and a Button wired up to the UpdatePanel via the Triggers collection. <%@ Page Language="C#" %> <script runat="server"> protected void Page_Load(object sender, EventArgs e) { Label1.Text = DateTime.Now.ToString(); if (IsPostBack) Label1.Text += " - Postback!"; if (ScriptManager1.IsInAsyncPostBack) Label1.Text += " - Async!"; } </script> <html xmlns="http://www.w3.org/1999/xhtml"> <body> <form id="form1" runat="server"> <asp:ScriptManager ID="ScriptManager1" EnablePartialRendering="true" runat="server" /> <asp:UpdatePanel ID="UpdatePanel1" UpdateMode="Conditional" runat="server"> <ContentTemplate>Panel 1:<asp:Label runat=server ID=Label1 /><br /> <asp:LinkButton runat=server ID="LinkButton1" Text="Update!"></asp:LinkButton></ContentTemplate> <Triggers><asp:AsyncPostBackTrigger ControlID="Button1" EventName="Click" /></Triggers> </asp:UpdatePanel> <asp:Button ID="Button1" Text="Refresh Panel 1" runat="server" UseSubmitBehavior=false /> </form> </body> </html> If I run this code and click on either of the buttons, I see "Panel 1:2/8/2010 3:38:41 PM - Postback!" I expected that clicking either button would cause a partial-page update for UpdatePanel1, that IsInAsyncPostBack would be true, and that " - Async!" would be appended to Label1. Any idea why IsInAsyncPostBack is always false?

  • C#- Executing Exe without using System.Diagnostics.Process.Start

    - by Lee
    Hi all, I have a program that crashes when I execute it with System.Diagnostics.Process.Start in C#, but works fine if I execute a shortcut or batch file that runs the exe. Are there any alternative means of executing programs in C#, or any reasons why Process.Start might not work compared to the shortcut or batch file? I'd rather not have to generate a batch or shortcut file to run the application. Thanks

  • What's the best way to create a Windows Mobile application with multiple screens in C#

    - by Joseph Earl
    I am creating a Windows Mobile Application in C# and Visual Studio 2008. The application will have 5-6 main 'screens'. There will also be bar (/area) with information (e.g. a title, whether the app is busy, etc) above the screens, and a toolbar (or similar control) below the screens with 5-6 buttons (with images) to change the active screen (i.e. the screens will share the top bar and toolbar) What is the best way to implement this? Use multiple forms, and just include the toolbar and top-bar in each Use a single form and something like the Tab control (but customised) to contain the screens Something else? Keeping in mind a) memory usage and b) time to switch screens. Thanks in advance. Any links, pointers etc are much appreciated.

  • Prevent checkins to SVN

    - by Joseph Mastey
    My team uses SVN for our software platform, and we create tags periodically to help keep module versions straight. Best practice, as I understand it, is not to modify a tag once it has been created. However, it seems that sometimes the temptation is too great and a modification is made to one of the tags. Is there a way to prevent these kinds of checkins, or at least make them a complete pain so that we can discourage them automatically? Thanks, Joe

  • cannot evaluate expression because a native frame is on top of the call stack and system.accessviolationexception

    - by Joseph
    I have this code using c#. public partial class MainForm : Form { private CvCapture VideoCapture; private IplImage frame; private IplImage imgMain; public MainForm() { InitializeComponent(); } private void btnVideo_Click(object sender, EventArgs e) { double vidWidth, vidHeight; try { VideoCapture = highgui.CvCreateCameraCapture(0); } catch (Exception except) { MessageBox.Show(except.Message); } if (btnVideo.Text.CompareTo("Start Video") == 0) { if (VideoCapture.ptr == IntPtr.Zero) { MessageBox.Show("badtrip ah!!!"); return; } btnVideo.Text = "Stop Video"; highgui.CvSetCaptureProperty(ref VideoCapture, highgui.CV_CAP_PROP_FRAME_WIDTH, 640); highgui.CvSetCaptureProperty(ref VideoCapture, highgui.CV_CAP_PROP_FRAME_HEIGHT, 480); highgui.CvQueryFrame(ref VideoCapture); vidWidth = highgui.cvGetCaptureProperty(VideoCapture, highgui.CV_CAP_PROP_FRAME_WIDTH); vidHeight = highgui.cvGetCaptureProperty(VideoCapture, highgui.CV_CAP_PROP_FRAME_HEIGHT); picBoxMain.Width = (int)vidWidth; picBoxMain.Height = (int)vidHeight; timerGrab.Enabled = true; timerGrab.Interval = 42; timerGrab.Start(); } else { btnVideo.Text = "Start Video"; timerGrab.Enabled = false; if (VideoCapture.ptr == IntPtr.Zero) { highgui.CvReleaseCapture(ref VideoCapture); VideoCapture.ptr = IntPtr.Zero; } } } private void timerGrab_Tick(object sender, EventArgs e) { try { frame = highgui.CvQueryFrame(ref VideoCapture); if (frame.ptr == IntPtr.Zero) { timerGrab.Stop(); MessageBox.Show("??"); return; } imgMain = cxcore.CvCreateImage(cxcore.CvGetSize(ref frame), 8, 3); picBoxMain.Image = highgui.ToBitmap(imgMain, false); cxcore.CvReleaseImage(ref imgMain); //cxcore.CvReleaseImage(ref frame); } catch (Exception excpt) { MessageBox.Show(excpt.Message); } } } The problem is after i break all and step through the debugger the program stops at a certain code. the code where it stops is here: frame = highgui.CvQueryFrame(ref VideoCapture); the error is that it says that cannot evaluate expression because a native frame is on top of the call stack. and then when i try to shift+F11 it. there is another error saying that system.accessviolationexception. the stack trace says that: at System.Runtime.InteropServices.Marshal.CopyToManaged(IntPtr source, Object destination, Int32 startIndex, Int32 length) at CxCore.IplImage.get_ImageDataDb()
