DLL Hell

Cyberghost

Hi

I've created a C# DLL on my own pc (VM to be accurate) which has a simple drag and drop function in it. I've added this to a page in NAV and it works perfectly.

Now the problem. When I try to use this DLL on a different server, the page does not compile. It does not seem to be able to understand the DLL, even to the point of not being able to drill now into the command using F5.

I have put the DLL in both the server and the rtc Addins folder. I have also added the details to the Control Add Ins page of NAV.

Any help or pointing to the right direction would be appreciated!

TIA

Chris

Hi all

Thanks for your help. I tried REGASM which came up with the error "REGASM Error ra0000 no types were registered"

A search on this lead to setting the ComVisible property to "true" in the assemblyInfo.cs file, which when applied to the dll, fixed the issue without having to run REGASM again.


Cheers

Is this a DotNet control, or COM?

DotNet. I'm working with NAV 2016

Check file properties. Is it blocked?
Does it reference additional dlls, others thank standard dotnet dlls which are loaded in gac?
Develope another simple dll. Check If that works correctly on other systems.
Is the same .net version installed on both systems?

When you declared the DotNet variable in your page, did you tell it to run on the client or on the NST?

If it's on the NST, then make sure the NST Service Account (might be an active directory account, might be NETWORK SERVICE) has read access to the Add-Ins directory where the DLL is located.

If it's on the client, then make sure the user's account has read access to the Add-ins directory.

And the last thought I have is that Visual Studio probably did something to register the DotNet control on your machine, and that step hasn't happened on the NST (or other client machines). You may need to use REGASM on it to get it registered.
