Unmanaged Dll in ASP.NET under IIS

[j_dodek]

Hi,

I try to load an unmanaged dll in on asp.net page, codebehind is c#.

The dll be first loaded by a Winapp. The dll provieds a shared memory so other Apps can get access by loading this dll. (this is working.)

Now i want to share it over the web.

I tried using dllimport. All is working fine under Asp.net Webdevelopement server (WebDev.Webserver.exe)

BUT: If i am using IIS (aspnet_wp.exe) i can not load the dll Hresult = 0x8007045A

If i do not start my Winapp so the dll is not be loaded asp.net will load my dll. But then the Winapp says no access to dll.

Is there a way to configure iis for multiple dll access ?

greetings
