Works fine over here. You sure you supplied the correct file path? Is it in the right format; BMP, JPG or PNG? Try adding Flip() just before Cls, or add this right after the LoadImage line: See if it produces an error. |

As Phoenix said, you need a Flip either before your Cls or before your Wend. With double buffered graphics, nothing will be displayed on-screen until Flip. On some computers, when a program is run windowed, the display might update even when Flip is absent - which may be why the program worked for Phoenix. Just add it and you've nothing to worry about. A minor style point -- in some fonts, 'l' and '1' look practically the same. I spent a moment myself trying to figure out why you were comparing 1 with itself. |

The flip worked wonderfully. Looking at my past programs I do have that in there. My mistake. Many thanks. as for my variable l. This is just a rough outline of a program to come many things will change. Thanks again i look forward to learning alot here. |

I is ok to use but it's a convention to use i (and j and k) for the index value in a loop. i.e. You'll find this convention used right across programming languages so I would suggest you follow it. In the place where your using i I'd also suggest calling it 'running' or 'isRunning' instead and set it to true. i.e. IMHO: 'while isRunning' expresses what the code is doing in a more natural way then 'while not i = 1'. |

actually i was using a lowercase "L" and as I said before this is just a rough beginning of a future function for a project I am working on.
