I am new to C++Builder 6, but I have used C++. My question is, how do I set a background for my form? When I open the application I want the background to have a specific image. I tried with Graphics::TBitmap but it says that the image is not valid even if it is bmp.

Graphics::TBitmap *BmpTabla = new Graphics::TBitmap;



try {

        BmpTabla->LoadFromFile("board.bmp");



}

__finally

{

    delete BmpTabla;

}  

Edit: I just changed the picture and worked fine.

Drop TImage component to the form, send it to back of the all controls, set the Align property to alClient.
In runtime

Image1->Picture->LoadFromFile("board.bmp");

The easiest way to have a custom background is to use a client-aligned TImage, like @serge suggested.

Another way is to load the BMP image into a Graphics::TBitmap object (like you are already attempting to do) and then use the Form's OnPaint event to draw the TBitmap onto the Form's Canvas.

The "image is not valid" error means you are trying to load a .bmp file that is not a valid BMP image. Double check the contents of the file.
