Form events - vbKeyTab doesn't register and neither do Mouse Clicks 1

[SBendBuckeye]

Hello All,

I have a class which is checking some things on the parent form using with events as shown in the skeleton below:

Private WithEvents mfrmParent As Form

Public Property ParentForm(Value As Form)
    Set mfrmParent = Value
    mfrmParent.KeyPreview = True
End Property

Private Sub mfrmParent_KeyUp(etc)
    If KeyCode = vbKeyReturn Then
        'Do Something
    End If
End Sub

The problems I have are as follow:

1. The KeyUp event does not trap the Tab key. If I put a breakpoint in the code, it is entered for all the rest of the keys but is never fired for the Tab key.

2. In the above code I use ActiveControl to determine which control has the focus. With the exception of the Tab key problem noted above, it is working well for keyboard entry. But, how do I handle mouse entry (eg user clicks in a listbox to select an item and then clicks on another control)? I thought there was a vbKey for the left mouse button but if there is, I missed it.

3. Can I use a generic mouse event in a similar manner to the KeyUp processing above? If so, is there some kind of correspondingpreview property I need to set to activate it? How do I determine which control has the focus in such a case?

Thanks in advance for any ideas, suggestions or best of all, a working code example to point me in the right direction!

Have a great day!

You will get only form events. Clicking on a control does not raise a form event. vbKeyLButton and vbKeyRButton are constants you are looking for BUT I believe that they only have meaning in KeyDown and KeyUp which are triggered only for keyboard action.

Thanks John, even though its bad news it kind of confirms what I suspected. Any ideas on why the Tab key doesn't fire the KeyUp event? Thanks again!

Have a great day!

Tab Key advances to next control.
Put
tab key vb6
into a Google search.

Thanks, I know what it does, what I don't understand is why it doesn't fire a KeyUp event like all of the other keys.

Have a great day!

Because it is considered a special key by the operating system, and gets 'eaten' before being passed on to the VB event handlers in order to do form navigation.
