MORE INFORMATION

Steps to Reproduce Behavior

1. Register an MFC-based ActiveX control in emulation using RegSvrCE.EXE.



2. Create a new Windows CE (HPC) Project in Visual Basic.



3. In Visual Basic 5.0, select Control Manager from the Windows CE menu and then select the MFC-based control from the list of controls. In VBCE 6.0, you must create a setup for the control in VCCE.



4. Visual Basic 5.0 select Synchronize from the Emulation menu to register the control for design-time use.



5. Load this control into the Toolbox by selecting Components from the Project menu and selecting the control.



6. Draw the control on the default form (Form1).



7. Delete the control from Form1.



8. Remove this control from the Toolbox by selecting Components from Project menu and deselecting the control.



9. Add the control back to Toolbox (see step 5).



10. Draw the control on Form1.
