Stop flickering

I am doing a real basic Screen Saver using a label to display system time. The label of course, bounces all over the screen. The problem is that is flickers so bad. There has to be a way to stop it from flickering? I'm just using a constant while loop, and incrementing the top and left properties of the label by one each iteration.

Thanks,

I have run into the same problem. I am not sure, in fact I hope I am wrong, but I think it is a VB limitation. If you wrote it in a faster language such as C++. I have a DLL written in VB that does sprites & stuff. It has the same problem, but I am hoping to have a friend rewrite it in c++. If it does work better, I will let you know where to get a copy.

I would say to use BitBlt, but I don't have any idea how you would do it on a label. So, no idea.

AaronC : Thanks for the input, please do send me that code if you get it.

Apollo : What is BitBlt? Where do I find more info on it?

Thanks,

If this program is going to run full screen and you are also going to be displaying a lot of images BitBlt probably will still be too slow. You might want to try Direct X.

This is everything I know about Bit Blit:

Declare Function bitblt Lib "gdi32" _
               Alias "BitBlt" (ByVal hDestDC As _
                Long, ByVal x As _
                Long, ByVal y As _
                Long, ByVal nWidth As _
                Long, ByVal nHeight As _
                Long, ByVal hSrcDC As _
                Long, ByVal xSrc As _
                Long, ByVal ySrc As _
                Long, ByVal dwRop As Long) As Long

You put all of that in a module. Then:

YOURIMAGELIST.Listimages( <INDEXNUMBER> ).Draw buffer.hDC, <THE LEFT OF THE INTENDED DRAW POINT> , THE TOP OF THE INTENDED DRAWING POINT, imlTransparent

That's where you specify the source of the image to redraw.

    Dc = bitblt(game.hDC, 0, 0, 480, 480, buffer.hDC, 0, 0, vbSrcCopy)

And the preceding line tells what box to copy the image to, and what buffer to use. I'd reccomend just making a picture box called game, and one called buffer, setting the one called buffer to true and then running the code. The only problem I have with this method, is that I cannot blit into negative space without a crash. This is why I can't make an overworld map... Different story.

If you have any questions on this method, my IM for AIM is AnseImaster.
