Keyboard behavior

Hello,

I have a question about keyboard events and keyboard behavior.

I have a diagram.
I can move in the document with the arrows keys, scrollbars and mouse wheel.

I have put the following code
Code
Select All
Ocx_Flowchart.KbdActive (true)
Ocx_Flowchart.KbdBehavior (0)	//kbScrollView


I don't want that the DEL key deletes an item.
How can I forbid this ? I don't need also cut/copy/paste actions.

Regards

You will have to disable KbdActive and scroll the diagram yourself in response to the KeyDown event:

Code
Select All
Private Sub fcx_KeyDown(ByVal KeyCode As Long, ByVal Shift As Long)
    Dim vkLeft, vkUp, vkRight, vkDown As Integer
    vkLeft = &H25
    vkUp = &H26
    vkRight = &H27
    vkDown = &H28

    If KeyCode = vkLeft Then fcx.ScrollX = fcx.ScrollX - fcx.ScrollRate
    If KeyCode = vkRight Then fcx.ScrollX = fcx.ScrollX + fcx.ScrollRate
    If KeyCode = vkUp Then fcx.ScrollY = fcx.ScrollY - fcx.ScrollRate
    If KeyCode = vkDown Then fcx.ScrollY = fcx.ScrollY + fcx.ScrollRate
End Sub


I hope that helps,
Stoyan
