So I have a LostFocus handler for my TextBox, and it gets called whenever I press "m", "o", or "-". Why is that? [Code] Is all that's there. I thought that I might have access keys or something interfering, but I would have to be pressing Alt, "-" wouldn't work, and there's also the fact that I have no access keys on the form. What's happening?

I think I'm close but how do you get what the text box is bound to? I'm trying to loop through all my textboxes and add a handler that on validation will insert a null if it equals string.empty. How to set the property manager by sending it the appropriate Binding context. I know that this code will not find textboxes in panels or ones that are on other controls, that's fine, for now. I'm also not sure how it will handle controls that are bound to different datasets.

remove an event handler from within the event handler?
I have a class that gets data from a hand scanner. When the scan is complete and the data is validated, the class fires a custom "ScanComplete" event and returns the data in a custom EventArgs.
In the calling program, I'm creating an instance of the scanning class and adding a handler for the "ScanComplete" event. In the event handler I get the data that was scanned and then remove the handler.
It seems to be working but it feels wrong to remove the handler while I'm running inside the handler. Will this cause a problem?
