[DUG] tMemo, Stop updating

[Myles Penlington]

No.No.No.

Do not use LockWindowUpdate for these kind of cases. LockWindowUpdate is
to be used for drag and drop cursor operations and nothing else (my
basic understanding of it's development - check up in Raymond Chen blog
about this)

If you want to stop drawing use (any window handle can be used)
          SendMessage( AForm.Handle, WM_SETREDRAW, 0, 0);
//Disable redrawing of window 
try

finally
            SendMessage( AForm.Handle, WM_SETREDRAW, 1, 0);  //Turn
drawing on again.
end

Instead.

Myles.

Try LockWindowUpdate with the handle of your TMemo, followed by
LockWindowUpdate(0) when you're done.

HTH,

Bloody stupid question I know, but I spent all day traversing 3 tons of
spaghetti code and my mind is mush.

Is there a way that I can tell a tMemo component not to keep updating
when I process all the lines.

I have a tMemo component with, lets say 5-10,000 lines. I want to
process through each of those lines updating certain ones where
necessary.

for i := 0 to Memo1.lines.Count - 1 do
    If (Memo1.lines[i] = 'I can use this line') then
         DoThingsToTheLine;

The problems is that I want to have the tMemo remain on the form, but I
don't want it to keep updating to try to keep up with the current line
that I'm processing.

I've already tried Memo1.Enabled := false, but the frigging thing still
keeps updating.

I don't want to make it invisible as it looks really horrible.

Any suggestions?
