Hi Everyone,

Is there a way of generating a keyboard character event and sending it to a
control on a form? For example, if I have a menu item called "Delete", I
would like to send a DEL character event to the currently active control on
the form.

Thanks.
 
Sorry, I forgot to mention that this is for VB.NET 2003.

Have you tried the System.Windows.Forms.SendKeys class?

I suggest you can set the focus to the target control first, then call the
System.Windows.Forms.SendKeys.Send method to send the keystroke, such as:

Control1.Focus()
System.Windows.Forms.SendKeys.Send("{DEL}")

Please refer to the following MSDN documentation for the details:

Hi Gary,

Thank you very much. It works like a charm. Cut, copy, paste also work
based on the control key sequences (eg "^C" for copy). However, I am not
able to get Select All to work. The "^A" sequence does not have any effect.
Is there a special command for this in a simple edit control?

Hi Bill,

I think this is because the TextBox control doesn't have a shortcut for the
Select All operation It doesn't work when you press Ctrl+A on a textbox
control directly neither.

I suggest you can use the SelectAll() method of the textbox control instead:

TextBox1.SelectAll()


Thanks!
