    StretchDIBits

    I write a software that take screen shots from remote PCs but when the screen is displayed at my window the remote screen is distorted and i can't' view the remote screen! This is part of teh code of the client that capture remote screens:

    BITMAPINFO BMPInfo;
    BMPInfo.bmiHeader.biSize = sizeof(BITMAPINFO);
    BMPInfo.bmiHeader.biWidth = Horz;
    BMPInfo.bmiHeader.biHeight = Vert;

    BMPInfo.bmiHeader.biBitCount = CPP;
    BMPInfo.bmiHeader.biPlanes = BitPlanes;
    BMPInfo.bmiHeader.biSizeImage = Horz * Vert * 4;
    BMPInfo.bmiHeader.biCompression = BI_RGB;

    BMPInfo.bmiHeader.biClrUsed = 24;
    BMPInfo.bmiHeader.biClrImportant = 0;
    HDC Mdc = GetDC(GetDlgItem(Spy,IDC_STATIC1));
    HWND mDlg = GetDlgItem(Spy,IDC_STATIC1);
    GetClientRect(mDlg,&rect);
    StretchDIBits(
    Mdc, // handle to DC
    NULL, // x-coord of destination upper-left corner
    NULL, // y-coord of destination upper-left corner
    rect.right, // width of destination rectangle
    rect.bottom, // height of destination rectangle
    NULL, // x-coord of source upper-left corner
    NULL, // y-coord of source upper-left corner
    Horz, // width of source rectangle
    Vert, // height of source rectangle
    (CONST void *)BufOfPixels, // bitmap bits
    &BMPInfo, // bitmap data
    DIB_RGB_COLORS, // usage options
    SRCCOPY // raster operation code
    );
    *** this code don't works??? Where is wrong???

    If you have nothing to do while waiting for an answer then please, read the Announcement: Before you post....
    And BTW, why do you think the others would have a lot of patience trying to read/understand your absolutely unreadable code snippet and absolutely uninfornative problem description?

    What is CPP?
    What is BitPlanes? This should be 1.
    Unless CPP is 32, BMPInfo.bmiHeader.biSizeImage is miscalculated.
    Why do you set BMPInfo.bmiHeader.biClrUsed to 24? This is saying that you want to use a color palette with 24 entries, but you do not define any entries. Did you mean to set BMPInfo.bmiHeader.biBitCount to 24?

    For future reference, please enclose your code between [CODE] and [/CODE] tags.

    I already modified my code but the image is still distorted! Here teh code:
    Code:
                                                                    BITMAPINFO BMPInfo;
    					memset((void *)&BMPInfo,0,sizeof(BITMAPINFO));
    					BMPInfo.bmiHeader.biSize = sizeof(BITMAPINFOHEADER);
    					BMPInfo.bmiHeader.biWidth = Horz;
    					BMPInfo.bmiHeader.biHeight = Vert;
    					BMPInfo.bmiHeader.biBitCount = CPP;
    					BMPInfo.bmiHeader.biPlanes = BitPlanes;
    					BMPInfo.bmiHeader.biSizeImage = 0;
    					BMPInfo.bmiHeader.biCompression = BI_RGB;
    					BMPInfo.bmiHeader.biClrUsed = 0;
    					BMPInfo.bmiHeader.biClrImportant = 0;
    			
    					HDC Mdc = GetDC(GetDlgItem(Spy,IDC_STATIC1));
    					HWND mDlg = GetDlgItem(Spy,IDC_STATIC1);
    					GetClientRect(mDlg,&rect);			
    					StretchDIBits(
    					Mdc,                      // handle to DC
    					NULL,                    // x-coord of destination upper-left corner
    					NULL,                    // y-coord of destination upper-left corner
    					rect.right,               // width of destination rectangle
    					rect.bottom,              // height of destination rectangle
    					NULL,                     // x-coord of source upper-left corner
    					NULL,                     // y-coord of source upper-left corner
    					Head.HAD,                // width of source rectangle
    					Head.VAD,               // height of source rectangle
    					(CONST void *)BufOfPels,           // bitmap bits
    					(CONST BITMAPINFO *)&BMPInfo, // bitmap data
    					DIB_RGB_COLORS,                  // usage options
    					SRCCOPY                   // raster operation code
    					);
    WHERE Horz,Vert ARE THE HORIZONTAL AND VERTICAL ACTIVE DISPLAY FROM THE SERVER, CPP IS THE COLORS PER PIXEL FROM SERVER AND BIT PLANES IS 1

    Where is the error???
