I want to use several functional Keys for some special features of my Mappoint control application. However, I cannot avoid the focus on mappoint control. I tried to set the Property KeyPreview of the main form to true, but my main form still cannot get the KeyDown event, e.g. When pressing F1, the mappoint online help will show up. This is not what I want. Any suggestions and ideas.

You'll probably have to use a API function to trap for the keypress. The mappoint control does not have a keypress event like a command button for example. If a command button had the focus you could trap the F1 key like this:

Private Sub Command1_KeyUp(KeyCode As Integer, Shift As Integer)
If KeyCode = vbKeyF1 Then
MsgBox "F1 Pressed" 'do whatever here
End If
End Sub

We are already kind of out of the scope of this forum so I'll leave it at that.

hehheheh another question that i don't have to ask (c:= the answer is as suspected though. is this an easy task (the key interceptor)?

they really make you jump through hoops to releive your VB app from the grips of the built in mappoint interface.

I tried several ways including Window 32 API and subclass etc, but still failed.

Who has a solution, please help me!

Any suggestions are appreciated very much!

set the keypreview to true for your form and use this code :

Private Sub Mpc_GotFocus()
Me.SetFocus
End Sub

Private Sub Mpc_MouseMove(ByVal Button As Long, ByVal Shift As Long, ByVal X As Long, ByVal Y As Long)
Me.SetFocus
End Sub

"Mpc" is the name of the Mappoint control in this case

This work fine for me, all the keys are intercepted by the form except the four arrows keys, I dont know why only this keys could not be intercept but for all other key it's good.

Bye

great! thanks for the tip.

cheers

Thank you very much, Coyote!
The remaining issue is need to place the mouse pointer on the map before you press the key.

In my case I use Mappoint in full screen in my car (www.media-car.fr.st) then the mouse is always on the map :)
