[DUG] tMemo, Stop updating
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?

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

RE: [DUG] tMemo, Stop updating
Look at and use BeginUpdate and EndUpdate. Can't remember if it's a method of TMemo or a method of the TMemo.Lines property.

Yep. Memo.Lines.BeginUpdate; // Do stuff Memo.Lines.EndUpdate; This works with anything that is based on TStrings.

Re: [DUG] tMemo, Stop updating
No, Thanks, but sorry that won't work. BeginUpdate will be for Data enabled components. This is a simple tmemo.

RE: [DUG] tMemo, Stop updating
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.

Re: [DUG] tMemo, Stop updating
Ah - Lines DOES have BeginUpdate and EndUpdate methods, and they work. LockWindowUpdate(memo1.Handle); seemed to also work too, but did something funny near the end where it started to update when it was about 80% through. Thanks people.

RE: [DUG] tMemo, Stop updating
Actually, if you start looking at the Tmemo code, which uses TMemostrings, you will find the begin update actually calls SendMessage(Memo.Handle, WM_SETREDRAW, Ord(not Updating), 0); so it is perfectly fine to call Begin adn end update on memos.

Jeremy Thanks Jeremy and others, Apologies, I was thinking of the objects TMemo and TCustomMemo. The property Lines (not TMemostrings that I can see) is a TStrings object which does indeed have the BeginUpdate and EndUpdate methods. I have used these and it works a treat. Thanks.
