hi dear i writing this code for loadbitmap i test many solution for load bitmap on the CBitmap without CImage but never run all solution for loadbitma

[mrai rasouli]

void CMRSMATHDlg::Loadit(TCHAR *destination, CDC &memdc)
{
CImage img;
PBITMAPINFO bmi;
bool reverse=false;
BITMAPINFOHEADER Info;
BITMAPFILEHEADER bFileHeader;
CBitmap *bm=new CBitmap();
CFile file2;
file2.Open(destination, CFile::modeRead | CFile::typeBinary);
file2.Read(&bFileHeader, sizeof(BITMAPFILEHEADER));
file2.Read(&Info, sizeof(BITMAPINFOHEADER));
BYTE ch;
int width = Info.biWidth;
int height = Info.biHeight;
if (height > 0)
{
reverse = true;
}
if (height<0)
height = -height;
int size1 = width*height * 3;
int size2 = ((width * 24 + 31) / 32) * 4 * height;
int gap = (size2 - size1) / height;
BYTE * buffer = (BYTE *)GlobalAlloc(GPTR, size2);
BYTE * gbuffer = (BYTE *)GlobalAlloc(GPTR, gap);
memset(gbuffer, 0, gap);
