MORE INFORMATION

Steps to Reproduce Behavior

1. Start a new Standard EXE project in Visual Basic. Form1 is created by default.



2. Add an OLE Container and a CommandButton to Form1. Click Cancel if prompted for an object type.



3. Add the following code to Form1's code window:




      Option Explicit

      Private Sub Command1_Click()
         OLE1.CreateEmbed "", "Word.Document"
         OLE1.DoVerb vbOLEUIActivate
         OLE1.SizeMode = 1
         With OLE1.object
            .ActiveWindow.DisplayVerticalScrollbar = True
            .ActiveWindow.DisplayHorizontalScrollbar = True
         End With
      End Sub 

4. Run the project by pressing the F5 key.



5. Click Command1 to embed a new word document in the container. The code automatically activates the document and shows the ScrollBars.



6. Type "Hello World" in the document.



7. Start moving the mouse around and/or click the start of the document. You should notice that the ScrollBars disappear shortly upon receiving these mouse events.
