• pcdoc4christ problem uncovered

  I have a VC++ MFC application in VS 2005. In this application I use CPropertySheet's in several locations. The program works fine for a while, but at some point the CPropertySheet's stop working, in such a way that when I click on a CPropertyPage tab, the tab for that sheet disappears completely or the controls on that CPropertyPage are all invisible. I'm guessing that I'm running out of resources, handles, me ...Show All

• BerndMei Exception within ATL when creating dialog

  Hello, Sorry if I'm bothering too much. I've gotten great help from here before. Here's the situation. I'm using Visual C++ 6.0. Within my IShellView I have a memberpointer to a dialog class that implements the CAxDialogImpl dialog. When the view loads I create this dialog dynamically by these lines:  m_pDialog = new CIsdSpreadDialog;  m_pDialog->Create(m_hWnd);  m_pDialog->ModifyStyle(WS_DLGFRAME | WS_BORDER | WS_T ...Show All

• mary_l Interop and Video For Windows

  Hello, I've written a library that uses the Video For Windows interface a long time ago. Back then, I didn't realize that interfaces were defined and that the functions were "C wrappers" so I used the C functions. I.e. I've been using AVIFileOpen instead of IAVIFile interface. I am trying to migrate to C++/CLI now and I am having a problem. My class looks something like: ref class MyVfw { public: IAVIFile *iavf; }; However, this create ...Show All

• loonysan Very simple webserver code

  I am making a very simple webserver -it does not need to have any sort of cross-platform compliance, it simply needs to work with IE6.  I have the following code which is simply supposed to read in a web page stored on the disk and serve it to the client.  Code follows (I cannot figure out how to format the text.. it's ugly): void SendLogin ( int clientNum ){ ifstream file ( ".\\HTM\\login.htm" ); if ( file == NULL ) re ...Show All

  In a non-CLR class I have a number of __events defined.

When I look at the error message it says: "cannot use __try in functions that require object unwinding". Further it is mentioned that "object unwind ...Show All

• Scott.B Dialog Resizing in Japanese XP

  In an 8-year old MFC/MDI project under Visual C++ 6.0, I use the default 8-Pt. MS San Serif.  For the first time I have heard from a Japanese XP customer that the dialog is being resized and labels are being shifted and/or truncated.  Experimentation showed that I could easily reproduce the behavior just by changing font dialog.  I assumed that XP was replacing an unknown font with some more universal font.  However, 8-Pt.
