Re: How to place a Bitmap in the center of a Cdocument document on startup

No this is NOT what I'm looking for. I once saw an article that displayed a Bitmap in the CDocument/View interface, but I've lost it somehow. I'll keep hoping someone has one and meanwhile I'll keep looking.

I'm still not sure what you mean but...did you try overwriting the OnPaint method of your view class (or OnDraw maybe?) and do something like this:

CBitmap bitmap;
bitmap.LoadBitmap(IDB_WHATEVER);
CDC MemDC;
MemDC.CreateCompatibleDC(&dc_of_view);
CBitmap *originalBitmap = MemDC.SelectObject(&bitmap);
BITMAP bitmapInfo;
bitmap.GetBitmap(&bitmapInfo);
CRect Rect;
GetClientRect(&Rect)
dc.BitBlt(Rect.CenterPoint().x - bitmapInfo.bmWidth / 2, 
          Rect.CenterPoint().y - bitmapInfo.bmHeight / 2, 
          bitmapInfo.bmWidth, 
          bitmapInfo.bmHeight, 
          &MemDC, 
          0, 
          0, 
          SRCCOPY);
MemDC.SelectObject(originalBitmap);

Yes, that's exactly what I was looking for. Question?: everytime the bitmap gets covered what command do I use to redraw it? (UpdateWindow??)

Once again i am not sure what exactly do you mean but to trigger redrawing of your view you can either use RedrawWindow[^] or InvalidateRect[^] (maybe in conjunction with UpdateWindow right after).

Windows has triggered a breakpoint in Gobang.exe.

This may be due to a corruption of the heap, which indicates a bug in Gobang.exe or any of the DLLs it has loaded.

This may also be due to the user pressing F12 while Gobang.exe has focus.

The output window may have more diagnostic information.

How to pass SendMessage() which is having base class as CWinApp?

Hi all,

I want to use SendMessage(). Through CMainFram class object it works fine but using CWinApp class as base class, it doesn't work. It is not giving any error, but SendMessage() is not called.

I use the following code.

CSampleCMSApp * poApp = (CSampleCMSApp*)AfxGetApp();
SendMessage((HWND)poApp,WM_DISP,0,(long)recv_data);

If i use poApp->SendMessage((HWND)poApp,WM_DISP,0,(long)recv_data);, it give error as
error C2039: 'SendMessageW' : is not a member of 'CSampleCMSApp'.

Can i use SendMessge for the class which is derived from base class as CWinApp?.
If yes, how can i do this.
If no, why i can't?

Please reply.

Thanks,
Abhijit

There are two versions of SendMessage.
One that is global and one that is a member of the CWnd class.

You are getting the error because CWinApp does not directly or indirectly inherit from CWnd, whereas CFrameWnd does inherit from CWnd.

You can use the CWnd member like so

AfxGetMainWnd()->SendMessage(WM_DISP, 0, (LPARAM)recv_data);

You BUY it from a bookshop.
Or maybe the equivalent of amazon.

If you want to steal other people's idea, this is the wrong forum for you.

If you want to buy a downloadable version, I'd encourage you to edit your original question too.

The last thing you want it an MFC book written by Petzold. I learned how to program windows from the guy's books, but his books on MFC and C# stunk. My two specific complaints are that he has complete disdain for the Visual Studio tools and his examples are very contrived and hard to translate to the real world.

Anyone who thinks he has a better idea of what's good for people than people do is a swine.

error LNK2001: unresolved external symbol _CLSID_IConverterSession
error LNK2001: unresolved external symbol _IID_IConverterSession
fatal error LNK1120: 2 unresolved externals

I dont know how to resolve this.

As far as i know,This is because you project short of some dll file or dib file,you may find the msdn to find it yourself,it will be easy,good luck.

The errors come because of I have used DEFINE_GUID
Now the problem with DEFINE_GUID is that we have to include INITGUID.h
otherwise compliler takes GUIDs as they are defined same where else so it comes with external unresolved error.

Thanks any way
