• Visual C++ msvcp71d.dll is not present in Visual Studio 2003 SP1

  msvcp71d.dll is supposed to be the STL debug version which you would get when you build multithreaded, dll, debug. The non-debug version, msvcp71.dll was updated in SP1, but the debug version was not. That doesn't seem correct to me Thanks, Bruce Sorry, this was a mistake. We didn't see the old version, we just didn't see any version at all. But it turns out it was because we are taking the files from an installation and building our own file tree and we missed this file. Bruce ...Show All

• Windows Forms C# namespace...

  Hi, i'm writing a shell extension in c# that will add two menu's to the right-click menu of explorer. Here is the problem. If i select one file and use the standard OPEN context menu all is well, but if i select two or more files and use the standard OPEN context menu it seems to want to run through the code for MY created menu. Here is the code in question: int IContextMenu.QueryContextMenu(uint hmenu,uint iMenu, int idCmdFirst,int idCmdLast,uint uFlags) { // The first id to use (should be 1) int id = 1; if ((uFlags & 0xf) == 0 || (uFlags & (uint)CMF.CMF_EXPLORE) != 0) { // Create a new Menu Item to add to the context menu MENUITEMINFO mii = new MENUITEMINFO(); mii.cbSize = 48; mii.fMas ...Show All

• Windows Forms Tab page loads slow due to background image and transparent controls

  Hi All, I have been struggling with this problem since weeks and still havent found the solution to this. I am using .Net 1.1. I have a form with a tabcontrol in it. I have defined a background image for each of the 7 tab pages in the tabcontrol. I have some 10 to 15 controls in each of the tab page. When i try to run the program and navigate through each tab, it loads very slowly. I determined with some tests that this problem occurs only when the background color of controls like "GroupBox", "Panel" and "labels" is transparent. If I dont have an background image then the loading is fast. And if I do have an image and the controls have any backcolor, its still ok. The problem comes in only when I have a ...Show All

• Smart Device Development timeGetTime() on WM5

  Met some link errors of timeGetTime() on WM5. I can not find the winmm.lib on WM5 SDK, which lib should I link with I tried to build a directshow filter on WM5, which has the "strmbase.lib" avaiable. But there are some link errors related to "CTransformFilter". I guess this is because the lib does not include all the classes defined in the baseclasses sample codes. Then I tried to recompile the baseclasses.

• Smart Device Development SQL error? Please Help Me

  please help me " Error" i want use dataset in windows mobile application and when i fill datagrid from dataset give fe unknown error please help me Picture for error link Error Picture It's not an "unknown error" but perfectly normal unhanded exception which indicates a bug in your code - luck of exception handling. You should add exception handling, catch this exception and print all information from it - exception type, error message, stack trace and error message from error collection (if applicable). After that you would be able to analyze this exception and figure our why it was thrown. In this case it’s probably thrown because connection to SQL Express can not be established.

• Visual C# Use this and base together?

  Hi, I was wondering if there is any way that I can use this() and base() together in a constructor. I mean a construct like this: public MyClass(string arg1, string arg2): base(arg1), this(arg2) { } thanks Thomas Hi, no you can not. If you have code that should be executed by any of your constructors but have to invoke the base constructor you need to create a method that is invoked by all constructors. For example: public MyClass(string arg1, string arg2) : base(arg1) { Initialize(arg2); } public MyClass(string arg2) { Initialize(arg2); } private void Initialize(string arg) { // TODO: Implement your code here. } ...Show All

• .NET Development BinaryReader floats and carriage returns

  How do you determine while reading floats from a file using binaryreader if you have reached the end of line(carriage return) Supposedly my binary file (.dat) contains a line of floats, then a line of strings. Before I can switch over and start reading singles I need to know where my line of floats end. I tried reading in the floats below and converting it to string in hopes that I would be able to pull out the "\r\n" or 10 13 carriage return values but it won't work. Any help would be much appreciated. private void button1_Click( object sender, EventArgs e) { String fileName fileName = @"C:\myfile.dat" ; FileStream fs = new FileStream (fileName, FileMode .Open); Binary ...Show All

• SQL Server Get field conditionally

  Hi folks I think this may be an increadibly simple one, but it's been driving me up the wall.

• .NET Development Connection pooling for SSAS using COM+ is not working properly.

  Hi, can anybody help   I tried using COM+ (servicedcomponent) for pooling connections of Analysis Services 2005 (SSAS). It seems that COM+ is establishing connections as per the object pooling attribute shown in the code below. When the client create instance of this class it gets assigned with already created object and gets a connection to SSAS. After firing MDX query using that connection, the client disposes the COM+ object, which should return the Connection to the pool for reuse but I saw in the Profiler that it logs off (close) the connection. If I create connections to SQL Server 2005 it works perfectly i.e. once the client disposes the COM+ object it returns the connection to the pool and next request automatically us ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. NoSuitableGraphicsDeviceException was unhandled

  Let me just say at the outset that I know nothing about C# (yet) and am trialing the XNA beta to try and get into it. I do know VB and some C, however. Once I had everything installed, I tried a few example programs including the Spacewar project, but I cannot run any of them. They build fine, but I can't run the .exe, and it crashes and asks if I want to send a report to MS. If I "Start Debugging" instead, I get the error "NoSuitableGraphicsDeviceException was unhandled" on the "this.GameComponents.Add(this.graphics);" line. I have no idea where to even start.
