Combo box to start at first character after user selects

29 Nov 2006 4:24 PM

The text in my combo box is longer than the control can show, when I click on
the down arrow, I can see the whole text, but when I select one of the items,
the text box of the combo box shows the end of the text. Due to limited room
I can not expanded the combo box control, so I want to show the front of the
text and not the default back of the text when a user selects a value.

Currently the user selects from the combo box, then has to hit the "home"
key to see the beginning of the text.

Hi Mike,

To make the cursor scroll to the first character of the line, we can
simulate pressing the Home key. We just send a key press message to the
control using SendKeys class. Here is an example.

    Private Sub ComboBox1_TextChanged(ByVal sender As System.Object, ByVal
e As System.EventArgs) Handles ComboBox1.TextChanged
        SendKeys.Send("{HOME}")
    End Sub

If anything is unclear, please feel free to let me know.

I get the error message, "SendKeys cannot run inside this application because
the application is not handling Windows messages. Either change the
application to handle messages, or use the SendKeys.SendWait method."

What does that mean?

Hi Mike,

Could you let me know what kind of application you're working on? Is it a
windows form app?

Hi Mike,

In VB2003, try to handle the SelectedIndexChanged event like the following:

    Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As Object,
ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged
        SendKeys.Send("{HOME}")
    End Sub

Does this working on your machine?
