Way To Disable Numeric Characters
Nov 11, 2009Well, it's really my first time to try Visual Basic .NET, then I realized that not all my previous experience with VB6 will work smoothly in VB.NET. I am creating a simple program that will enter a name in the TextBox and will greet them by using the MessageBox class. But I wonder, since the TextBox that I'll be using is for inputting a name, I want to "trap" all numeric keys in my keyboard, I just don't know how to do it. This is fair easy in VB6, using the Text1_KeyPress(KeyAscii As Integer) subroutine.

Highlight Numeric Characters In A Maskedtextbox?
Apr 14, 2011I am using a masked text box to allow users to enter a serial number. The problem is that this serial number has to be communicated over the phone and people seem to be having trouble differentiating between O and 0 and I and 1.
I thought that a good solution to this might be some way of highlighting which characters in the textbox were numeric characters (as opposed to alphabetic characters). Obviously there is no way to do this without using a richtextbox and then I lose the masking ability. Highlight numeric characters in a maskedtextbox?
