Hi,

I was wondering if someone can help. I have created a class library and generated (.tlb) file within visual studio and have successfully managed add this to a project that I need to use this file (within microsoft access).
The only problem is when I make the call to the class within this it’s looking for a reference within that library. I have tried copying all the files from my release folder to the location where I have the access database application without any success.

The message is "could not load file or assembly or one of its dependencies. The system can not find the specified file". I am really not sure what i need to do.

Any help would be appreciated.

Regards,

Ross

If you don't create strong key name for your library you have to place the dll into the same directory. In your case it would have to be the same directory as Excel.exe. If you want to avoid that then give your assembly a strong name.

Project properties > Signing Tab > checkmark "sign the assembly" in the dropdown select <"New"> on the next dialog type in name of your library then un-check "Protect my key with password". click OK. Recompile.

Then you need to use RegAsm.exe with the /codebase switch. This allows mscore to locate your library any place on the system.
C:\Windows\Microsoft.NET\Framework\v4.0.30319\regasm.exe "C:\mylib.dll" /tlb:mylib.tlb /codebase

Hi,

I asked another question the other day that allowed me to add this reference this via the access application by creating a .TBL file:

http://www.experts-exchange.com/Microsoft/Development/MS_Access/Q_26831994.html

I then tried to call a class within this and the access application gave the following message:
"could not load file or assembly or one of its dependencies. The system can not find the specified file”

The message gave the name of another .dll file that I reference in the visual studio application that I compiled as a .TBL file.

Do I need to regasm each of the other .dll files that I added into that project?

Thanks again
