How do I convert a value in a textbox to a real number so I can perform some
math ops on it? I understand I will need to validate the textbox's input to
make sure it is a real number and not a string so any suggestions along
those lines are also appreciated.
Thanks,

OK, I did some more searching and found I can use the Convert class
(convert.todoub le) to convert the string to a double. It works but is this
the best way?
I'm still looking for how to validate the input so any help there is
appreciated.
Thanks,
Scott

Hi Scott,
Convert will thrown an exception if it fails. You can use
bool success = double.TryParse (...)
You can also limit the TextBox input to numbers only + any special characters like decimal point etc. Handle the TextBox.KeyPres s event for this.

I have been working with vb code to automate a salary increase process

that once I set the even rounded value back to the text field it adds
a 01 on the end of the raounded value (i.e. 1234.56 is 1234.5601)

I have a win forms project, for simplicity's sake, lets say that I

The problem I have is when I run the app, the very first record the

is never called, I checked). Navigating to the next and subsequent
