Selecting An Item From The DBCombo


Click event of the DBCombo is activated not only when the user clicks on an item in the list part of the DBCombo but also when clicking in the textbox part. This is undesirable when an application requires procedures to be carried out when the user selects an item from the list part but should not be carried out when the user clicks in the textbox part.
The following code enables a selection procedure to be activated only when the user selects an item from the list. The selection may be made either by clicking with the mouse or by using the navigational keys.

Highlight all by clicking in box
<!---Declaration--->
none

Highlight All
<!---Code--->
Private PreviousDBComboText As String
Private MouseDown As Boolean
Private Sub DBCombo1_Click(Area As Integer)
If MouseDown And DBCombo1.Text <> PreviousDBComboText Then
ItemSelected
End If
MouseDown = False
End Sub

Private Sub DBCombo1_KeyUp(KeyCode As Integer, Shift As Integer)
Select Case KeyCode
Case vbKeyDown, vbKeyUp, vbKeyPageDown, vbKeyPageUp
ItemSelected
Case Else
End Select
End Sub

Private Sub DBCombo1_MouseDown(Button As Integer, Shift As Integer, x As Single, y As Single)
PreviousDBComboText = DBCombo1.Text
MouseDown = True
End Sub

Private Sub ItemSelected()
'Enter here any code which needs to be activated after a selection has been made
MsgBox DBCombo1.Text & " was selected."
End Sub
;
