VB calls
 

hello telents

i would like to know that which are the vb api call who draws logo on video screen ? like demoware trial version etc who is generally based on timer so how to catch them.

Regards...

what is logo and what is video screen in your case?
better would be to show some pic.......

I guess its up to WinAPI to draw things, and/or Dx/OGL in case of real video

Just look at these 3 images

and this logo looks like gif/jpg/png and text or it may draw runtime

Thanks for reply

In VB6 can be BitBlt API from gdi32.dll, also DirectX can be used for this. Check DLL dependencies to see what function is used. If it's VB6 you can use P32Dasm to see external Dll calls.

It it is VB6 it could also use the internal commands like Image.Left and such. Maybe no external dll is involved at all.

Can be, just analyze exports and you will see it immediately :)

Thanks a lot for your kind reply , i got list but how can i such sure that which api is moving that gif or text accross video screen ?

You can find all reference CALLs in exe (if it's not too much), set BPX there and you will see
