Welcome MoZhe, you will need to provide more detail regarding your question; are you experiencing a runtime or compile time error? (Missing line?)

He means that he can't see the line that he draws on the screen.

MoZhe: The reason is that as soon as you create a sprite, Dark GDK introduces a blue backdrop and that covers the lines. The solution is to redraw the lines every loop. A game usually has a game loop that is still missing from your program. Try this:

could also be the nvidia card bug. i had the same problem (your code should still work). at the very top of your main function add the line dbSetWindowOff(); and you will go into full screen mode instead of windowed mode. when i started working in full screen mode, about 90% of my problems/bugs went away.

The problem i think its that the line is outside the loop like Mireben said. Try his code and it should work
