Re: HowTo: Unregister a DLL/Control when the File no longer Exists

Tech-Archive recommends: Fix windows errors by optimizing your registry

I have a project group, in a specific location on disk, that contains
several projects. There is the main EXE and a few ActiveX DLLs.

The main project references one of the DLLs, which in turn references
another DLL. So far so good.

Periodically, I copy the entire directory hierarchy to another, similar,
location, and call it version 2; so the parent directory MyProject still
exists, but now there is one alongside it called MyProject #2. I begin
working on #2.

When I am happy with the changes in #2, I delete the original directory
structure altogether.

When I look in the references, I can still see the original controls. How
can I remove them without wading through the registry in the vain hope
that
I know what I am doing? I realise that I can never include one of these as
a
reference because I get an "Error loading DLL" message, but in time I get
a
proliferation of entries in the references section to files that do not
exist, and at best this creates clutter but at worst it means that I have
to
work through them until I find the right one to include. [Of course, until
I
delete the earlier version, it is still possible to include the wrong
file,
which is more serious]

TIA

That whole process is soooo wrong on soooo many levels.... <g>

I highly recommend that you look into VSS and how to manage project/binary
compatibility, but for now obtain a decent Registry Cleaner utility and
periodically run it.

Also you may want to create a Context Menu tool for Explorer to make
registering and unregistering easier.

Place the following in a ".Reg" file.

REGEDIT4

[HKEY_CLASSES_ROOT\dllfile\Shell]
@="Register"

[HKEY_CLASSES_ROOT\dllfile\Shell\Register]

[HKEY_CLASSES_ROOT\dllfile\Shell\Register\command]
@="regsvr32.exe %1"

[HKEY_CLASSES_ROOT\dllfile\Shell\Unregister]

[HKEY_CLASSES_ROOT\dllfile\Shell\Unregister\command]
@="regsvr32.exe /u %1"

[HKEY_CLASSES_ROOT\.ocx]
@="ocxfile"

[HKEY_CLASSES_ROOT\ocxfile]
@="OCX File"
"EditFlags"=hex:00,00,01,00

[HKEY_CLASSES_ROOT\ocxfile\Shell]
@="Register"

[HKEY_CLASSES_ROOT\ocxfile\Shell\Register]

[HKEY_CLASSES_ROOT\ocxfile\Shell\Register\command]
@="regsvr32.exe %1"

[HKEY_CLASSES_ROOT\ocxfile\Shell\Unregister]

[HKEY_CLASSES_ROOT\ocxfile\Shell\Unregister\command]
@="regsvr32.exe /u %1"

Save the file, then run it. The next time you right click a DLL or OCX, the
option to register or unregister it should be there. You can combine this
with Search in Explorer to list all the Dlls and Ocxs in a particular folder
structure.
