Installing to GAC using Deployment Project

[Guest]

Hi,

I have written an App in vb.Net (2003) which references Excel 2000. This
creates a Interop_Excel.dll which I need to reference in my project. All OK
so far.
I had to modify the Interop_Excel.dll and renamed it tm_Interop_Excel.dll
after modification. This new dll has a strong name and all the correct
attributes.

If I create a deployment project for my app, the tm_Interop_excel.dll is
placed in my application folder.

However I need this dll to be installed in the GAC. I can do this manullay
using GACUTIL, and all is OK.

When I create an installer, using VS 2003, I drag the dll form my
application folder into the Global assembly folder. (file system on target
machine).

When the installer is run, the tm_Interop_Excel.dll is placed into the GAC
but without a codebase entry and my app does not work. If I then run the
GACUTIL -i the codebase entry is added and all is ok.

I have found the GACUTIL is missing on some target computers so I cannot
relie on it being there.

So my question is, How do I create an installer which will automatically
place my tm_Interop_Excel.dll into the GAC correctly without using the
GACUTIL.exe.

Thanks in advance

You're doing the right thing, but where is this codebase value you are
referring too? Codebase is usually referred to in the context of Regasm.exe
or a config file. Gacutil just puts assemblies in the GAC, like the
deployment project does.

Phil,
Many thanks for the swift reply.

When I use the GACUTIL, then find the entry in he GAC, right click and
look at properties, the is an entry for Codebase, which references the
location of the dll I installed using the GACUTIL.

If I check the GAC after I use the installer there is no entry for the
codebase on the dll's properties.

Do I need to do anything special because it is a interop dll?

Tim

Hi Tim,

If you need to mimic the process of 'gacutil' and/or 'regasm' because
they may be not in the target machine, you can use:


[C#]
using System.EnterpriseServices.Internal;
....
Publish p = new Publish();
// for GAC Installation
p.GacInstall(file); // for gac installation
....
p.GacRemove(file); // for gac removing
....
p.RegisterAssembly(file); // for registering assembly for interop
....
p.UnRegisterAssembly(file); // to unregister assembly
[/C#]

Thanks Sebastian

I will try this out as an alternative, many thanks
