Ok, this time I have a question.... I'm developing a shareware astronomy program using VB. I need "transparent" buttons or picture objects in one of my maps (which is a form). What I mean by "transparent" is that the background needs to show thru except for the buttons bitmap. I know how to make transparent bitmaps using API calls, and I can place those as I need, but the problem is I need them to respond to a mouse click event (like a button or picture object does on a VB form) My current thought is to get the mouse X and Y coordinates on a form-click and compare to a table of coords in which I've stored the X & Y positions. This seems like it would work, but I'm looking for some other ideas... In a related question. I've heard that some icon drawing programs can create icons with transparent backgrounds. Has anyone tried loading one of these into a VB picture? Would it get the "transparent" effect I am looking for? If anyone could tell me the name of the program and where I can find it (ftp, CompuServe, BBS etc) I'll try it myself... I have IconDraw but (at least the version I have) doesn't have transparency... Thanks!!! - Galen - galenr@hpgrla.gr.hp.com
