Backspace - Delete Text In The Textbox Using This Is To Highlight And Hit DEL?
Jun 5, 2010
Here's my code snippet:
Private Sub txtLogin2_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtLogin2.KeyPress
'// Ceci empêche l'utilisateur d'écrire des caractères ASCII ou même des espaces..
e.Handled = Not Char.IsLetterOrDigit(e.KeyChar)
End Sub
It works fine and dandy except for one issue... the only way to delete text in the textbox using this is to highlight and hit DEL... But what if I wanted to simply back space... Any suggestions?
I'm trying to create a BMI Calculator with VB 2010. I have 2 TextBoxes for weight and length. I want to make sure that the user can only enter numeric (0123456789) values and also backspace and delete.
I'm trying to highlight the text when the textbox gets focus, like an address bar of browsers. I'm using this code so far:

I have built an addin for outlook that has a usercontrol shimmed into the interface. Everything works wonderfully EXCEPT for one textbox on one subpanel of the control. I have tried everything I can think of, but have not been able to resolve the issue:
The textbox *(A regular System.Windows.Forms.Textbox) functions as you would expect in any application with one exception. It will NOT accept the backspace key. So much so that the KeyDown, KeyPress, KeyUp events will not even fire when I press the backspace key. There does not seem to be any parameter suppressing it, and the control has focus. What is even stranger is that it works completely fine if you hold down the shift key while pressing the backspace key.

I have 3 text boxes that update with each other. One the user inputs the text, two the text is used for translation and instantly deleted, and three displays the translated text. If I need to backspace the code updates the translation adding double of each letter I delete. I need a way to skip all of the application code every time the backspace key is held. My current code here (full dictionary cut to save space).
