1. Can you capture an image of the current desktop in Dark Basic Pro?
2. (less important) Can you compare two images in that if the images are exactly same then the vaule will be "1"?

I'm trying to make a bot for a game in Dark Basic Pro.

If you are talking about screenshots then unfortunately last I heard they did away with the SAVE IMAGE command in DB Pro (which is horribly short sighted of them) but there might be a .dll that you can use. If you are talking about capturing an image of the user's desktop then I don't think you can.

You can do a pixel by pixel comparison between two images to see if they match up. Use the POINT command to get the colour value of each pixel and store them in 2 screen sized arrays (ie. DIM screen_1(800,600) ) and then compare the values (ie. IF screen_2(1,1) = screen_1(1,1) THEN match = 1 ).

There is that helper thing for Classic Dark Basic to capture the screen but I would rather use pro of course.

SAVE IMAGE is back in

There's no way that I know of to capture the desktop, although if the DBC helper is a DLL, then you should also be able to use it in DBPro.

Heh, I forgot to say that although it *is* back, it's slightly broken - something you'll notice if the image you save is not square
