SYMPTOMS
If a modal form is brought up over a form that contains an OLE Container Control on a page of a pageframe, when the modal form is closed, the OLE Container Control will be visible even when the page that contains it is not active.



WORKAROUND
For the form that runs atop the form with the OLE Container Control, set the WindowType property to 0 - Modeless.

-or-

In the Deactivate code for the pages that contain OLE Container Controls, move the OLE Container Control object off the page by setting its Left property to a high value. Move the object back to its proper position in the Activate code of the page.

Workaround One
Set the WindowType to 0 - Modeless for any forms brought up over forms that have OLE Container Controls on inactive pages.

Workaround Two
The following workaround moves the OLE Container Controls that are on inactive pages to a place outside the form boundaries, so modal forms can be used.

For the form that holds the pageframe with pages containing OLE Container Control objects, perform these steps:

  In the Init code of each of the OLE Container Controls, place: THIS.Left=3500            && Some artificially high value   In the Activate code of each page, place: THIS.Olecontrol1.Left=35  && desired placement when on active page   In the Deactivate code of each page, place: THIS.Olecontrol1.Left=3500  && artificially high value 

Each OLE Container Control will now be visible only when it is on the active page.



STATUS
Microsoft is researching this behavior and will post new information here in the Microsoft Knowledge Base as it becomes available.



Steps to Reproduce Behavior
 Create a form called Mainform.  Add a command button and place the following code in its Click event: DO FORM Modalfrm. </li> Add a Pageframe.</li> Add an OLE Container Control (such as Outline.ocx) to each of the two pages of the Pageframe.</li> Save the form.</li> Create a form called Modalfrm, and set its WindowType property to 1 - Modal. Save the form.</li> Run Mainform, and press the command button to bring up Modalfrm over Mainform.</li> Exit the modal form.</li> Both of the Outline controls will be visible on the active page of the pageframe.</li></ol>
