Easy, simple way to make a textbox only accept numeric, or alpha chars?????

[Joey Picerno]

I have read some of the articles on this site and others reguarding this issue and all of them involve custom controls or writing a class to accomplish this simple task. Someone has got to know a simple easy way to accomplish this with a few lines of code. I mean VB6 had this property for the textboxes but .NET doesnt and you have to make a custom control or write a class??? This doesnt make any sense. If anyone knows of a simple way to make a textbox accept ONLY numeric and ONLY alpha, please let me know. Thank you in advance.

pass the 'e' argument of the keypress event of the textbox into either routine: Public Sub KeyPress_Numeric_Only(ByVal e As System.Windows.Forms.KeyPressEventArgs) Select Case Asc(e.KeyChar) Case Keys.Back, Keys.D0 To Keys.D9 'continue Case Else e.Handled = True End Select End Sub Public Sub KeyPress_Alpha_Only(ByVal e As System.Windows.Forms.KeyPressEventArgs) Select Case Asc(UCase(e.KeyChar)) Case Keys.Back, Keys.A To Keys.Z 'continue Case Else e.Handled = True End Select End Sub
