Hi,
I want a Regular Expression to allow anything except a particular word i.e. "select". How do I do this? I've tried excluding each letter individually ^[^s][^e][^l][^e][^c][^t]$ but this doesn't work if a letter happens to match e.g. "string" (the first s matches)
Thanks in advance.
 
I know what you mean

I've had this issue before and it's might near impossible to do. One thing you can do is find lines that contain "select" and exclude them from processing. For example, if you were reading a file or stream that is broken into separate lines you could test each line to see if it contains "select" and only process the ones that fail the test. Maybe this helps. :-\
 
Possible solution for your dropdown list

Well...I imagine you've got a drop down list that's populated with the word "Select a dog breed" or something like that at the top to direct users what to do.

If that is the case, and you know what the directive message is, i.e. "Select a dog breed", then in the dropdown_changed event handler for that control I would just check for the directive message and do nothing if the "Select a dog breed" message is the text value.

Does this make sense?

Another alternative is to have the control label direct the user what to do, and have an empty entry as the top choice in the drop down list. You could then just check for non-emptiness in the event handler. :)
