I don't think that .GetData( CF_DIB ) is returning valid DIB data and here's why: If I strtofile( .GetData( CF_DIB ), "TEMP.DIB" ) I can't view TEMP.DIB using VFP's image control, MS Paint, or the IrfanView image utility.

Hi Malcolm,

First, I'm using VFP7 (I'm still waiting for my MSDN shipment). So I don't know if there is a different return data between VFP7 & VFP9.

In VFP7 the data is properly returned by .GetData(). The returned data is using BITMAPINFO (BI) structure. It contains BITMAPINFOHEADER (BIH) structure, then followed by arrays of RGBQUAD structure.

So:
1. parse BIH, then calculate the image size that will be needed by BITMAPFILEHEADER (BFH)
2. create BFH, fill in the structure. As from the example at the link:

BITMAPFILEHEADER hdr; // bitmap file-header
PBITMAPINFOHEADER pbih; // bitmap info-header 

hdr.bfType = 0x4d42;        // 0x42 = "B" 0x4d = "M" 
// Compute the size of the entire file. 
hdr.bfSize = (DWORD) (sizeof(BITMAPFILEHEADER) + 
             pbih->biSize + (pbih->biClrUsed * sizeof(RGBQUAD)) +
             pbih->biSizeImage); 
hdr.bfReserved1 = 0; 
hdr.bfReserved2 = 0; 

// Compute the offset to the array of color indices. 
hdr.bfOffBits = (DWORD) sizeof(BITMAPFILEHEADER) + 
                pbih->biSize + pbih->biClrUsed * sizeof (RGBQUAD);

3. save BFH + the returned data = BMP file
