deleting lines - SyntaxEditor for Windows Forms Forum

Posted 19 years ago by karl - Senior Software Architect, Shelltools, LLC

how can i delete say teh top 500 lines from a document?

basically i am implementing a console kind of output in this case, and once it gets over a certian amount of times, i want to clip off some of them..

also i noticed in the console situation, with the autoscrolling, it can get very slow and jerky when you are adding hundreds of lines in a loop.

Hi Karl,

You'd have to get the start offset of the document line... probably something like this...

int startOffset = editor.Document.Lines[499].StartOffset;

Then call the Document.UndoableDelete method to delete offset range 0 to startOffset.

We're trying to improve speed and memory usage in v4.0 so hopefully that will help.
