Convert Text to Single -- Convert.ToSingle -- Input string was not in a correct format
I have a textbox "MyBox" that users input text into. In this case, it is numeric (for which I can ignore non-numeric input, but that's not the question). I do something like this:
MyValue = Convert.ToSingle(MyBox.Tex
However, if the text is empty or alphabetic (e.g., "Hello, world."), I get an error "Input string was not in a correct format." Of course, I can pre-test for that, but I was wondering if there was some easy step that I was overlooking, like one that change non-numeric values to zero instead.

The second post is how I'm doing it, now (with IsNumeric). Probably not any better way.
how much better do you want it to get?
Or
Try
MyValue = Convert.ToSingle(MyBox.Tex
Catch
MyValue = 0
End Try
That way you don't have to do 2 checks, you just go ahead and do it and treat any failure as a 0.

end if
