checking for F10 in a textbox 1

how do you check if f10 has been pressed in a textbox using the keypress event

Do you want to test for a certain textbox or all textboxes on a form?

If you want to test for the whole form, try this code, otherwise you can just modify for a certain textbox...

Public Sub Form1_KeyPress(ByVal sender as Object, ByVal e as System.Windows.Form.KeyPressEventArgs) Handles MyBase.Keypress
if (Microsoft.VisualBasic.Asc(e.Keychar)) = 121 then
' insert your code
End if
End Sub

Check this link for the ascii chars for all keyboard keys..

A side note controls won't fire a Keypress event for function keys or control keys either. Only the form seems to accept these values. To read more on this check out this article.

To get around this and only check to see if F10 was pressed for one text box try this

Protected Overrides Function ProcessDialogKey(ByVal keyData As System.Windows.Forms.Keys) As Boolean
If stuff Then
If keyData = keyData.F10 Then
MsgBox("F10 was Pressed&quot
End If
End If
End Function

Private Sub textbox1_Enter(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtCatNo.Enter
stuff = True
End Sub

Private Sub textbox2_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtCatNo.Leave
stuff = False
End Sub


stuff is a global private variable of type boolean. While the focus is on textbox1 the event for F10 will be fired otherwise it won't.

Use the KeyDown Event.

Private Sub txtFileFilter_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles txtFileFilter.KeyDown
if e.KeyCode = Keys.F10 then
MsgBox(e.KeyCode)
end if
End Sub

How do I send a different key when, for example, Enter is pressed, and I want my form to act as if Tab was pressed?
