Steps to Reproduce Behavior

Method 1: Use the Olecont.vbp Sample

1. Start Visual Basic and open the sample project Olecont.vbp. By default this project is located in the following folder:

   Program Files\DevStudio\VB\Samples\PGuide\olecont




2. Press the F5 key to run the project.



3. Select New from the File menu.



4. In the Insert Object DialogBox, select Create New and "Microsoft Excel Worksheet" under Object Type.



5. Repeat steps 3 and 4 so that you have two MDI children with embedded worksheets.



6. Put some data in some cells on both worksheets.



7. Select a cell on the 2nd worksheet. From the Edit menu, select Clear and then All.



8. Repeat step 7 with the first worksheet. The menu commands do not react and cells are not cleared. If you choose some other menu items, they are either ignored or cause an IPF and shut down the program.

Method 2: Create New Standard EXE Project

1. Create a Standard EXE project in Visual Basic. Form1 is created default.



2. Set Form1's MDIChild property to True.



3. Place an instance of the OLE control on Form1. In the Insert Object DialogBox, select Create New and "Microsoft Excel Worksheet" under Object Type.



4. Add a new form (Form2) and repeat steps 2 and 3 for Form2.



5. Add an MDIForm (MDIForm1) to the project and paste the following code in to MDIForm1:

   
         Private Sub MDIForm_Load()
            form1.show
            form2.show
         End Sub 




6. Select Project1 Properties from the Project menu and set the Startup Object as MDIForm1.



7. Press the F5 key to run the project.



8. Double-click in Worksheet on Form2 and enter some numbers in some cells.



9. Repeat step 8 for Form1.



10. Switch back to Form2 and, from the Edit menu, select Clear and then select All.



11. Repeat step 10 for Form1. On one of the forms, the command works but on the other form, the command fails to respond.
