How to highlight a field when I click on it.

Question

I'm not sure how to even ask for what I need.  I have a form with many input fields.  Here is what I want to do.  When I click on a field I want the contents to highlight and then if any new data is entered it will overwrite the current contents.  The way it is now, when I click on a field if there is any data in the field I must first use the delete key or the backspace key to get rid of the current data.  If I just type the new data it just inserts it.  For example, if the field has "Bob" in it and I want to replace it with "Jack" I have to delete the contents.  If I start typeing I may end up with "BobJack", or "BoJackb" or "BJackob" or so on.  I want to overwrite the existing data.

I hope I am clear in what I am wanting to do.

Thanks for any help.

Answer 1

Your "fields" are presumably textboxes, so all you need is something like this:

   Private Sub TextBox1_Enter(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.Enter, TextBox2.Enter
      Dim TB As TextBox = CType(sender, TextBox)
      TB.SelectAll()
   End Sub

Thank you Dave.  Yes, the fields are testboxes and I have 30 of them.  Do I need your code for each of them?

Hi Philip, I agree with Dave :)

No you don't need for each textbox this code, just add to the end of first line after 'Handles' keyword  your controls:

   Private Sub TextBox1_Enter(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.Enter, TextBox2.Enter, TextBox3.Enter....
      Dim TB As TextBox = CType(sender, TextBox)
      TB.SelectAll()
   End Sub

For now they are TextBox1, TextBox2, TextBox3... just add the other controls at the end

Regards Muli :)
