HOWTO: Create an OCX View with the MMC Snap-in Designer for Visual Basic

• Microsoft Management Console, versions 1.1, 1.2
• Microsoft Visual Basic Professional and Enterprise Editions for Windows, version 6.0

SUMMARY

The Microsoft Management Console (MMC) Snap-in Designer for Visual Basic offers the ability to create result views based on ActiveX UserControls. The use of ActiveX UserControls allows for greater flexibility in what can be displayed in the Result View window. This article outlines the steps needed to create an OCX View.

MORE INFORMATION

Steps to Create an OCX View

1. Start Visual Basic and select a new SnapIn project from the New Project dialog box.



2. Add a new UserControl to the project. By default this new UserControl will be named UserControl1.



3. Open the SnapIn1 Designer. Under the Static node, right-click the ResultView node, and then select Add New Result View -> OCX View from the pop-up menu. By default, the new Result View will be named OCXView1.



4. Right-click the OCXView1 node and select Properties from the pop-up menu.



5. When the property dialog box appears for OCXView1, set the ProgID text field to the ProgID of the project's UserControl (Snapin.UserControl1). Close the property sheet when done.



6. Right-click the main parent node, Snapin1, and select Properties.



7. When the Snap-in property sheet appears, set the Default Result View value to OCXView1. Close the property sheet.



8. Open the UserControl1 code window, and add the following code:




Private Sub UserControl_Click()
    UserControl.BackColor = vbRed
End Sub 

9. Compile the project and start MMC.



10. Load the snap-in into MMC and select the SnapIn1 scope item. The UserControl will be rendered in the result view window.



11. Click anywhere in the result view window and the background color of the window will change to red.

Notes

• An OCX View will not display when a snap-in is run from within the Visual Basic integrated development environment (IDE). The SnapIn project must be compiled to an executable to work properly.



• A UserControl will resize to fill the Result View window, regardless of the window's size. Any controls sited on the UserControl will not be automatically repositioned when the UserControl is resized.



• By default, a UserControl is only initialized once, the first time it is used in a Result View. The ResultViews_InitializeControl event will only be fired once for each OCX View. An OCX View provides the AlwaysCreateNewOCX property to change this behavior. With the AlwaysCreateNewOCX property set to TRUE, a new instance of the UserControl is created each time a Result View is rendered.
