- I have a DOS terminal emulator which is now being used in a DOS session
- under Windows 3.1. All works fine except that in some cases the window is
- not completely updated usually after it has been cleared and is being
- totally rewritten. The application is written in assembler and writes
- directly to the screen buffer. Windows is in 386 enhanced mode and the
- problem does not occur when running in full screen mode. It is thus
- something to do with the updating of the window and this can be
- demonstrated by moving another window on top of it and then away again
- which causes it to be redrawn correctly.
-
- I have tried changing the WindowsUpdateTime value and this had no effect.
- What I need is a call similar to the Topview Int 10 function FF to tell
- Windows that the window has been updated. Does anyone know if such a
- Windows call exists and what its specification is?
-
- Many thanks in anticipation
