WARNING: NtUserExcludeUpdateRgn at H:\trunk\reactos_clean\win32ss\user\ntuser\ntstubs.c:113 is UNIMPLEMENTED!
Semi Implentet ExcludeUpdateRgn from user32.dll
Have this already done, just need to commit it. Not here at work.
Possibly, but can you try changing the focused cell? Does it still draw a black rectangle shifted wrt. the selected cell?
Zoomed (SS98) in and there might be an alignment issue here, not sure if its NtUEUR or stretch BLT. Zoom out the blinking cursor goes to the above row like SS97 shows.
There are update issues too, while selecting other row cells.
Hmm ok, so the NtUserExcludeUpdateRgn might be only one tiny part in the whole issue.
Small "example" of usage: http://www.delphigroups.info/3/e6/40448.html
I'm wondering whether we have some (possibly interactive) tests for ExcludeUpdateRgn.
I don't think interactive tests are needed to test this.
