How to delete all the text from a file?

[meckeard]

How would I go about deleting some or all of the text in a file?

I am using a browser based WYSIWYG editor and I need to overwrite the existing text with the new text.

I know how to write to or append to the file. But this adds to the original text and I can't do this.

Ideally, I would like to delete all but the first line in the file, as it's actually a user control (.ascx) and I need the first line to stay. However, I can always grab it and rewrite it when I replace the original text.

Thanks.

you would probably be best to delete the file and recreate it with only the text you need.

I tried, but I get the following error:

Exception Details: System.IO.IOException: The process cannot access the file "c:\inetpub\

http://wwwroot\editor2\controls\CurrentNews.ascx"

because it is being used by another process.

This is an asp.net user control, so maybe that's the reason I get the error?!?

did you open the file in your developing environment (like in VS.NET) while the application was trying to delete it?
