Whatever your issue I doubt that anyone will be bothered to wade through all of your code: you should only post the fragment that is the issue and if anyone needs more they will ask.

Nobody is going to dig into your code to find the problem in such amount of code. Try posting only relevant code.
Furthermore, when something like that happens, your first reflex should be to use your debugger to narrow down the problem. You'll get much faster results than asking a question on a forum.

{ if(cf.Read(&BFH, sizeof(BITMAPFILEHEADER))!=sizeof(BITMAPFILEHEADER)||
BFH.bfType!='MB'||
cf.Read(pDib, dwDibSize)!=dwDibSize)
{
delete [] pDib;
pDib = NULL;
return FALSE;
}
}
在 try 中的 BFH.bfType!='MB' 应该改为 BFH.bfType!='BM'

Solution 3

cgpsview1.LoadBmp((LPTSTR)(LPCTSTR)szFileName00);

u can change :
eg

cgpsview1.LoadBmp(szFileName00.c_str());
