void ShowBMP(HWND hWnd, char *filename) //, TCHAR szFileName[MAX_PATH])
{

// TCHAR szHello[MAX_LOADSTRING];
// LoadString(hInst, IDS_HELLO, szHello, MAX_LOADSTRING);
// int height, width; PAINTSTRUCT ps;
HDC hdc;
// HWND hWnd = GetWindow(hWnd, NULL);
hdc = BeginPaint(hWnd, &ps);
 // TODO: Add any drawing code here...
RECT rt;
GetClientRect(hWnd, &rt); long lStillWidth = rt.right - rt.left;
    long lStillHeight = rt.bottom - rt.top;
    BITMAPINFOHEADER* lpbi = new BITMAPINFOHEADER;
BYTE* lpBuf = ReadBMP(lpbi, filename);
lpbi = (BITMAPINFOHEADER*)lpBuf; int nW= lpbi->biWidth;
int nH= lpbi->biHeight;
BYTE* lpData=(BYTE*)lpBuf +  sizeof(BITMAPINFOHEADER);// - 10;// + sizeof(RGBQUAD);
SetStretchBltMode(hdc, COLORONCOLOR);
::StretchDIBits(hdc,0,0,lStillWidth,lStillHeight,0,0,nW,nH,lpData,(BITMAPINFO*)lpbi,DIB_RGB_COLORS,SRCCOPY);// ::StretchDIBits(hdc,250,250,nW,nH,0,0,nW,nH,lpData,(BITMAPINFO*)lpbi, DIB_RGB_COLORS,SRCCOPY);// DrawText(hdc, szHello, strlen(szHello), &rt, DT_CENTER);
EndPaint(hWnd, &ps);
