I have been trying to get CreateEmptyImage to work in a program. However I get an "Invalid Property" error all the time. So I made a very simple one form, one control program to test it and *that* worked. So then I started stripping stuff out of my main app to see where the problem was. I stripped it back so that the 2 programs are now identical - even in a text editor there is no difference apart from the form name and white space. But still one works and the other does not. I may be a newbie to Basic4PPC but I know enough computing to know that something odd is happening here! I can't work it out and am hoping someone can help!
