[Dev-C++] bitmaps

[Vlada D. <dj...@im...>]

Hi, everybody.

I've been trying to make a program that opens a bitmap file, reads it's
BITMAPINFOHEADER and RGBQUAD parts, and puts them in BITMAPINFO structure. I
managed to read the first header part, but I'm having problems with RGBQUAD.
When I comment out this part, the program works fine, but when I uncomment
it, the program just exits without any warning message. Here's the code:

-----------------------------------------------------------

        {LPTSTR szFileName=TEXT("bitmapa.bmp");

            HANDLE
hFile=CreateFile(szFileName,GENERIC_READ,0,NULL,OPEN_EXISTING,  //open file
for reading
                        FILE_ATTRIBUTE_NORMAL,NULL);
            if(hFile==INVALID_HANDLE_VALUE)
              MessageBox(hwnd,"Error","Can't open file",MB_OK);
            else
              MessageBox(hwnd,"FileOpen sucess","Success",MB_OK);
            BITMAPINFO bmpInfo;
            DWORD btCount;
            SetFilePointer(hFile,sizeof(BITMAPFILEHEADER),NULL,FILE_BEGIN);
//set pointer to begining of the file

ReadFile(hFile,&(bmpInfo.bmiHeader),sizeof(BITMAPINFOHEADER),&btCount,NULL);
//read BITMAPINFOHEADER to bmpInfo;

ReadFile(hFile,&(bmpInfo.bmiColors),sizeof(RGBQUAD)*(2^bmpInfo.bmiHeader.biB
itCount),&btCount,NULL);//read RGBQUAD to bmpInfo
            LPTSTR szOutput;

sprintf(szOutput,"width=%i,height=%i",(int)bmpInfo.bmiHeader.biWidth,(int)bm
pInfo.bmiHeader.biHeight);
            MessageBox(hwnd,szOutput,"Result",MB_OK);
            CloseHandle(hFile);}
---------------------------------------
I hope you guys can tell me what's wrong and is this the right way to do
this. Thanks
