1. I need help
I would like someone to help me with IDE. The Code Editor is getting kernel
crashes when Find\Replace is used and also for autocomplete of "procedure"
with "end procedure". The crash happens in the onPaint_syntax routine which
is written with a lot of direct API calls. I'm a novice as far as API is
concernted.
If anyone has the time and inclination, please contact me.

Judith,
I just had a look at this routine and BOY!, is this a minefield. I guess
what its trying to do is write the lines of text to a offscreen bitmap,
using various fonts and colors, then blasting that to the window.
There is one thing I can suspect straight off. Replace the line ...
hDC = c_func( synGetDC, {hWnd} )
with
hDC = getDC(Syntax)
And remove the line ...
c_proc( synReleaseDC, {hWnd,hDC} )
I say this because the DC is supplied by Windows already during a Paint
event and this can be gotten by using the getDC() routine. It is
auomatically released when the paint event returns. If the app gets its own
DC, then there maybe some weird conflicts.
I'm tempted to rewrite this using plain win32lib code 'cos there is nothing
you couldn't do there without resorting to API calls. Unless speed is really
improved by doing this...???
