private withevents ce as CommandBarEvents ' Sub Test() Dim c as CommandBarControl set c = Application.VBE.CommandBars("Menu Bar").Controls(2) set ce = Application.VBE.Events.CommandBarEvents(c) End Sub ' private Sub ce_Click(byval CommandBarControl as Object, _ Handled as Boolean, CancelDefault as Boolean) ' Put event-handling code here End Sub '
How this works
This class ctlCmdEvent can act both as ParentClass and ChildClass.
SetEvents method collects all CommandBarControls and creates a new ChildClass for each control. This ChildClass is able to get its control event (Click). ChildClass directs the event back to ParentClass which rises event back to the first user object.
With Visual Basic 6 create a new Add-In project and modify the created designer code to read like the following :
option Explicit ' private withevents mCmdEvent as clsCmdEvent 'to catch all command 'button events '------------------------------------------------------ 'this method adds the Add-In to VB '------------------------------------------------------ private Sub AddinInstance_OnConnection(byval Application as Object, _ byval ConnectMode as AddInDesignerObjects.ext_ConnectMode, _ byval AddInInst as Object, custom() as Variant) ' on error GoTo error_handler ' 'save the vb instance set VBInstance = Application ' 'Initialize every CommandBar Events from VB set mCmdEvent = new clsCmdEvent mCmdEvent.SetEvents VBInstance ' ' ............. Exit Sub ' error_handler: ' MsgBox Err.Description ' End Sub '------------------------------------------ ' This event raises for every commandbar button click '------------------------------------------ private Sub mCmdEvent_Click(byval CommandBarControl as Object, _ Handled as Boolean, CancelDefault as Boolean) ' 'place your handling code here ' Dim CB as CommandBarControl set CB = CommandBarControl ' Select Case CB.Parent.Name & CB.Id Case "Standard186" 'Run Command Button End Select With CB MsgBox "VB Command:" & vbCrLf & _ "Parent: " & .Parent.Name & vbCrLf & _ "Id: " & .Id & vbCrLf & _ "Index:" & .Index & vbCrLf & _ "Type: " & .Type & vbCrLf & _ "Caption: " & .Caption & vbCrLf & _ "Description: " & .DescriptionText End With ' End Sub ' '
