View 3 RepliesIs there any way to exchange backspace with delete key. I hav used this code in key_down event of rtb

endif

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 have an if clause where I compare a textfield with the value of a datareader.
It looks a little like this if me.txtfield1.text <> reader("field1") OR me.txtfield2.text <> reader("field2") ETC... I do this for a lot of field.
But now I want to check if field2.text is string.empty and if it is I want to skip the comparison for that field.

synchronizing a combobox with a textfield. I have a form with a textfield and a combobox. The combobox is populated with the department name from the database when the form loads. I would like the textbox to display the corresponding department number when the user selects a department name from the combobox. I have tried using the SelectedIndexChanged event of the combobox but I can't seem to code it to work. This is the code I'm trying to use but it is displaying "DEPARTMENT" in the textbox. Department Code is the primary key of the table.

View 1 RepliesI'm writing an in-house intranet application in ASP.NET and VB.NET. My 'customers' are beginner to medium-level users. All of our browsers are IE8 and above, standard.The application works great, except for one thing. The backspace key. When a user types an invalid number into a textbox, a RegularExpressionValidator and ValidatorCalloutExtender fire off and notify the user. Perfect. Except that, when the user closes the popup warning and notices the cursor is still flashing in the textbox, he/she feels it's time to hit the backspace key and delete that pesky field value.
Unfortunately, the browser interprets this action as a desire to go 'back' into the page history. My boss is screaming. His bosses are screaming. I have a headache.So, how can I turn off this behavior? I still need the backspace to eliminate characters in the textbox, but nothing else. Company policy here: Backspace is to delete characters from the screen. Nothing more, nothing less.
