• Visual C++ MessageBox memory leak/corruption problem

  I have a main thread that displays a message box using CDialog's MessageBox function. And there's another thread that exits the application. Termination of the MessageBox (without the user pressing "OK") is corrupting memory or causing memory leaks. In debug mode it says "user breakpoint is reached in code .. ". Is there a simple way to close the messagebox before terminating the application so that there won't be memory corruption or memory leaks Things I tried are: * Using pClassPointer->SendMessageToDescendants(WM_CLOSE, 0, 0, TRUE, FALSE); This is not working! I do not know why! P ...Show All

• Windows Forms Transparent Panel Headaches

  Hi, I'm having a really frustrating problem when using transparency in a Panel, if anyone has any suggestions I would really apreciate it. My problem is the following: I have a Form with a Panel contained on said Form. The Panel has the BackColor property set to "Transparent". I would like the background of the Form to be visible through the panel (I assume this is what setting the BackColor property to transparent means ). When my form first loads all is well - the underlying Form is visible through the transparent Panel. However, if I minimize the Form and then Restore it - now my transparent Panel displays what is underneath the ...Show All

• Visual C++ (hopefully simple) COM question

  I'm trying to write a program that uses the Groupwise administrative objects API, and I'm having some trouble with a COM object... When I run CoCreateInstance, it returns REGDB_E_CLASSNOTREG. Does anyone know what causes this error and how I can stop it Note that I have the groupwise client already installed, which supposedly includes all of the necessary DLLs. Here's the code that causes the error: //Create Instance if(FAILED(x = CoCreateInstance(CLSID_System, NULL, CLSCTX_INPROC_SERVER | CLSCTX_INPROC_HANDLER | CLSCTX_LOCAL_SERVER, IID_IADSystem, (void**)&pIGWSystem))) { printf("Failed to create instance\n"); if(x == RE ...Show All

• Visual C# How to ping a server

  Hi there, I'm looking for an easy way to ping a server. I found another thread, telling that "System.Net.NetworkInformation" would be the right source to look at. But I can't find this class! So how can I ping a server Thanks, Finch82 Not all of the classes are included in the default references when you start a project. Go to the references folder in the Solution Explorer and right click then click add reference. Scroll down in the list until you see the files that start with System. You should see something there that includes System.Net in the name. Add this to your project and then you'll be a ...Show All

• Visual Studio Team System How to spawn Team Explorer

  Is it possible to launch Team Explorer client from a web page Something like URL to link from Team Project Portal. Preferably pointing directly to the related project. obs.: I've tried to do that using a script with shell command, but my users have VS2003 installed in their machines too, and in some cases it gets launched instead of VS2005 (when running DevEnv.exe). Thanks, Max You could tweak "Content Type" to something IE does not understand, like "application/devenv" and it will open the file in devenv after the usual warning.  Nearly all of the VS registered content types are text/plain or ...Show All

• Visual Studio Must uninstall VS2003?

  Installing VS2005 beta 2 gives me an error at setup.exe saying I must uninstall VS2003 pro.  Just to restate, it's not asking to uninstall 2005, it definately says 2003  What's up with that !!!! I am doing some investigation here to see if we can repro this problem.  I believe there should be no block for VS2003 ENT and that the only blocks should be for VS2005 previous builds. Can you try running Aaron's tool to remove old WHidbey builds and then see if install works   I think we may just have the incorrect error message in the UI and that the actual problem is that we are detecting ...Show All
