MORE INFORMATION

Steps to Reproduce Behavior

Start Visual Basic and select a new SnapIn project from the New Project dialog box.
Open the SnapIn1 Designer from the Project Explorer window and add a new Toolbar and Image List control. By default these news controls will be named ToolBar1 and ImageList1.
View the properties of the Image List control, and insert a new bitmap image that is not 16x16.
Give the Key field a value for the new image.
View the properties of the Toolbar control, and set the ImageList field to ImageList1.
On the Buttons tag, insert a new button on the toolbar.
Set the Image field to the Key field of the bitmap image in the image list.

Open the Snapin1 Designer's code window and paste in the following code:

Private Sub Views_SetControlbar(ByVal View As SnapInLib.View, ByVal Controlbar As SnapInLib.MMCControlbar)

    Controlbar.Attach Toolbar1
    
End Sub

Compile the SnapIn project and load it into MMC.
Select the default static node, SnapIn1. The error mentioned in the "Symptoms" section appears.
Change the bitmap image in the Image List control to a 16x16 bitmap.
Retest the SnapIn. This time the error does not occur.
