In accordance with the specifications for building and exposing ActiveX
controls, Visual Basic uses a resource file to store the toolbox bitmaps
for each UserControl in a compiled OCX. Design-time clients can then load
and display these bitmap images in a "control toolbox" without having to
load or create running instances of these controls.
By default, Visual Basic stores these images with a base resource
identifier starting at 30000. Consequently, when adding your own resource
file to a Visual Basic ActiveX control project, you should avoid using
resource IDs that might conflict with these values.
MORE INFORMATION
The toolbox image resource ID for a UserControl is registered on the system
in the ToolboxBitmap32 registry key under the CLSID for the control.
