I have been experimenting with the BitBlt command in VB and can't seem to get the results that I want. What I want to do is load a picture in one picturebox and copy it over to another picturebox utilizing stretch or transparent modes. I can get this to work ONLY if both pictureboxes are visible on the screen, which is not what I want. I want the source hidden either not visible or off the screen. How can I get this to work? As a side note, I am using eVB which has very limited picturebox commands. It does not support LoadPicture which I know is an alternate way of getting what I want in VB6.
Can someone explain why the source picturebox must be visible on the screen for BitBlt to work? I thought it was just copying a memory map from one object to another, so why does it have to be visible? Does anyone have a solution for what I want?
