I guess I'm missing some obvious stuff.
But I'm having trouble doing the following:

Delete all lines of text that does not contain "myString".

Any help would be appreciated.

Thanks

Click to expand...

Try replacing: "(^.*myString.*$)|(^.*$)" with "$1", that should delete all
lines but the ones containing "myString". (use RegexOptions.Multiline, so ^
and $ match for start/end of lines)
