I'll have to check that Sash stuff out too...
Anyway, if you can't get that to work, try the VC++ resource editors. They are simple to use and allow you to create powerful MFC-based programs even if you don't know MFC (sounds impossible, but its true). Also, if you're looking to learn real Windowing/Messaging/GUI stuff this summer, and you want to do it for Windows, I'd recomend you find a copy of Charle's Petzold's
Programming Windows. It's a GIANT 1400 page book and is far and away the best one on the Windows API that I have ever read (and it presents it in such a way that you will be able to make the switch to MFC fairly easily later on). Anyway, that was my summer reading last year, and it's what I used to write my
RoboGUI program.
Anyway, if you need any real-time help, I'll be on ICQ for the rest of the night while I work on some of my programming projects. #152894206.
