BitBlt? how?

I'm trying to use bitblt but sounds like it doesnt work
I have this at the top of my class

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

I just converted all the Longs to Integers
When I use it, it doesnt do anything
and for the picturebox's DC I'm just using picturebox.Handle (no idea what I'm doing:confused: )
so why isnt it working? how can I use bitblt?!!! :(

we always keep autoredraw property to true while drawing in picturebox,but there is nothing like this in vb.net, you have make a call bitblt it has worked but i beleive your picturebox has not redraws itselft to show the change, fortunately we have an event paint in picture box, which will be fired when a picture repaints itsself, u can place your call to function here and call picture box refresh method to triger this event. i think u should use picturebox.handle.toint32 or some thing like that for dc
i have not done this, but i think it should work please tell me about result

Wait, what are you trying to do exactly? Why do you want to use bitblt?

Oh, yeh. I remember.

Are you using the beta version of the framework? Did you install the framework service pack?

This is too strange.
