In article <5339@blue.UUCP> linneweh@motcid.UUCP (Louis Linneweh) writes: One of the best ways to do this is using the GET , PUT statements to save your window contents in an offscreen buffer. I use this in a lot of the basic programs I wrote. After I would draw the window contents, I would copy the window to the offscreen buffer. If an update event occurs then you just blast the image back into the window. I works great and fast. Its backwards to the way you should do it but until I release my Offscreen support libraries for Quickbasic there is no other way. One problem in the above method is that is doesn't copy color information. -- ___________________________________________________________ Matthew Mora | my Mac Matt_Mora@sri.com SRI International | my unix mxmora@unix.sri.com ___________________________________________________________
