This article was previously published under Q186391 SYMPTOMS
When you unregister an ATL ActiveX control using "REGSVR32.EXE /u," not all
registry keys are removed. Specifically, the following subkeys under
HKEY_CLASSES_ROOT\CLSID\{<guid>} are not removed:
- Insertable
- MiscStatus
- ToolboxBitmap32
CAUSE
The .rgs (Registrar Script) file created by the ATL Object Wizard has a
duplicate entry for the Programmable subkey. When the unregistration code
encounters the duplicate, it aborts and fails to remove any other keys that
come after the duplicate entry.
RESOLUTION
Open the .rgs file and remove the duplicate entry.
For example, in the following code remove the second occurrence of the line
"ForceRemove 'Programmable'":
Sample Code NoRemove CLSID
{
ForceRemove {C875C6A0-E8F9-11D1-8F73-00C04F9403C2} = s 'PolyCtl
Class'
{
ProgID = s 'PolyCtl.PolyCtl.1'
VersionIndependentProgID = s 'PolyCtl.PolyCtl'
ForceRemove 'Programmable'
InprocServer32 = s '%MODULE%'
{
val ThreadingModel = s 'Apartment'
}
ForceRemove 'Control'
// Remove the next line. It's a duplicate that causes the parser to
// abort.
ForceRemove 'Programmable'
ForceRemove 'Insertable'
ForceRemove 'ToolboxBitmap32' = s '%MODULE%, 1'
'MiscStatus' = s '0'
{
'1' = s '131473'
}
'TypeLib' = s '{C875C692-E8F9-11D1-8F73-00C04F9403C2}'
'Version' = s '1.0'
}
}
To avoid this problem in future .rgs files generated by the wizard, remove
the same duplicate line from the following files. The wizard uses these
files when creating the .rgs files:
C:\Program Files\DevStudio\SharedIDE\Template\atl\Control.rgs
C:\Program Files\DevStudio\SharedIDE\Template\atl\Ie3ctl.rgs
STATUS
Microsoft has confirmed this to be a bug in the Microsoft products
listed at the beginning of this article. This problem was corrected in
Visual C++ version 6.0 for Windows.
