COMException error

C

Chris Clement

I added a mask COM control to my app and now some computers are getting a
"Class not registered" COMException while others are not. I have verified
that they all have the DLLs on the same directory. Any idea what could be
causing this? Thanks.

Here is the detailed error:

Chris,

When you create assemblies for interop, you not only have to make sure
that the interop assemblies are shipped, but that the COM component that it
references is properly installed on the machine. In this case, you have to
make sure each machine has the masked edit control installed as well.

Hope this helps.

Nicholas,

Thanks for the reply. Unfortunately, I don't know much about COM
components. Can you give me a tip as to how I can install the masked edit
control? All I have are the DLLs.

Thanks for your help.

Chris

Chris,

Well, I am not sure, because I don't know the specifics of the control
you are trying to install. When you install a COM component, it can be as
little as just registering it (in which case you just use REGSVR32 or an
install program to do this), or the registration in addition to other
registry entries, files, other dlls, etc, etc.

When you say you have the DLLs, does that mean you have the COM dlls, or
the interop dlls?

I have two interop dlls: Interop.MSMask.dll and AxInterop.MSMask.dll. They
both are required. I tried doing the regsvr32, but didn't work. So you are
saying that there is something else that needs to be installed on the
computer for this to work?

Chris,

You misunderstand. You need to register the DLL that contains the COM
component. The interop assemblies do not contain this, they only act as a
bridge to the original COM component.

Cool. Got it working. Found the COM component in the path column in the
Add/Remove Items of the VS.NET toolbox. Had to register the msmask32.ocx
(or wise installmaster did anyway) on the computer. That did the trick.

Thanks, Nicholas!

Nicholas,

Thanks for the reply. Unfortunately, I don't know much about COM
components. Can you give me a tip as to how I can install the

masked
edit
control? All I have are the DLLs.

Thanks for your help.

in
message Chris,

When you create assemblies for interop, you not only have to make
sure
that the interop assemblies are shipped, but that the COM

component
that

references is properly installed on the machine. In this case,

have
to
make sure each machine has the masked edit control installed as well.

Hope this helps.

I added a mask COM control to my app and now some computers are
getting
a
"Class not registered" COMException while others are not. I have
verified
that they all have the DLLs on the same directory. Any idea what
could
be
causing this? Thanks.

Here is the detailed error:
