Remarks
If you are using Microsoft Visual Basic Scripting Edition (VBScript) in a Microsoft Outlook form, you should typically use the GetInspector method to refer to the Inspector object associated with the form, for example:
Set myInspector = Item.GetInspector
Example
This Visual Basic for Applications (VBA) example uses the ActiveInspector method to obtain the currently active Inspector object and enables the display of keys in ToolTips in the inspector.
Sub DisplayKeys()
'Enables key in ToolTips
Dim myolapp As Outlook.Application
Dim myinspector As Outlook.Inspector
Set myolapp = CreateObject("Outlook.Application")
Set myinspector = myolapp.ActiveInspector
'Test if an inspector is active
If Not TypeName(myinspector) = "Nothing" Then
myinspector.CommandBars.DisplayKeysInTooltips = True
End If
End Sub
