I'm trying to configure access, launch permissions along with set run as to one of our custom DCOM application.
I have already gone through these links dcomcnfg functionality programmatically
and http://www.myitforum.com/articles/11/view.asp?id=9323 (downloaded c++ DCOMPerm library)
I tried the code from the first link above as is written by "longofest" but the following line of code
var value = Registry.GetValue("HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Ole", "DefaultAccessPermission", null);
always gives me back a null value,however when I looked into the registry entries on my machine the "DefaultAccessPermission" entry for Ole registry key does have a binary value there then why I always receive a null back, no idea.
Secondly I tried the c++ library downloaded from the second link above and tried to do a COM call to one of the methods with DLLImport attribution (for automating the launch permissions for the DCOM object) but some marshalling issue is not letting me pass in the C# types corresponding to C++ types and spitting out an exception that says PInvoke cannot return variants.
I couldn't find anything concrete after googling for several hours, any help on this account will be more than appreciated.
Never worked with C++, got very poor knowledge of this language.
Update:The null value issue is solved but I don't know how to set access permissions and set run as. I have seen in c++ code that for setting access permission the code needs a domain and username but what is the c# equivalent of that, no idea....
