Hi, I have Lead Tools v15 and I am using VS6 (VC++) on XP (sp 3)
My goal is to display a byte buffer to the screen. Below is my code, it doesn't work can you please help me.

        byte *buf = new byte [100];
        LBitmap lbmp;
        LBuffer buffer(buf, 100);
        LMemoryFile memFile(&lbmp);
        int ret = memFile.Load(buffer);

memFile.Load returns -9 which is invalid file format. But I dont know what it wants.

You are getting the error "invalid file format" because you are trying to load an image from an empty memory buffer. You can't use the LMemoryFile::Load function to load an image from an empty memory buffer. The memory buffer must be in any supported image file format and bits per pixel, whether compressed or uncompressed.

For more information, please read the help topic "LMemoryFile::Load" in the LEADTOOLS C++ Class Library documentation.

Thanks,
