Check if a OCX or DLL is registered.

I've build a addin that needs two references in order to run:
MSOWC.dll & Msflxgrd.ocx

These files sometimes aren't present on some of the PC's that will use my addin, so how do I check that they are registered?

Something like:

VB Code:

If ReferenceExists("MSOWC.dll") = False Then
    msgbox "False"
    Call RegisterRef("MSOWC.dll") ' Register reference
Else
    msgbox "True"
End If

Is there a way of using Regsvr32.exe in V6B code?

Package your addin in an installation and setup package that includes both of these files.

That will both load and register them for you.

I've built my comm addin in VB6, after compiling it the end result is a DLL file.
(Made for Outlook 2003).
How do I create a "installation and setup package" for a DLL COMM add-in?

It doesn't really matter what the product is, you can use an installer to install anything.

Use either the Package and Deployment Wizard or Inno.
