Question about .NET COM

[DLee65]

I am sort of new to .NET COM registrations. I have inherited a wise studio project and am in the process of converting it to InstallShield 2012.

The application is a .NET app with some VB objects.
The previous developer had constructed the installer so that several of the COM objects would register after they were installed via a batch file using

%WINDIR%\Microsoft.NET\Framework\v4.0.30319\regasm

A set of commands would look like this:

%WINDIR%\Microsoft.NET\Framework\v4.0.30319\regasm AmazingCharts.MainBusinessObjects.dll /unregister >> %FILENAME%
%WINDIR%\Microsoft.NET\Framework\v4.0.30319\regasm AmazingCharts.MainBusinessObjects.dll /tlb: AmazingCharts.MainBusinessObjects.tlb /verbose

I am thinking that there has to be a better way of managing registering these files than through a batch file after install.

This is a basic MSI installer and I would rather use the MSI to manage the registration since it can remove the registration after too.

BTW, there is a batch file to manage the removal of the registration of the files as well.

Thank you for any information you can pass along my way.

Just make the assemblies (DLLs) key files of their own components and set .NET COM Interop = yes on them.

During the build, InstallShield will call Regasm /regfile and harvest the results into your registry table.

This generally works although there are some exceptions. (See my earlier post from today ).

Say goodbye to another custom action. 🙂 Life is good.
