Access 'Interop.dsofile.dll' via reflection

[sanjay1983]

Hi Everyone,

I am stuck to access file properties using 'Interop.dsofil e.dll'. I dont want registration of this assembly in system registry. I am using reflection to achive this, but at the time of create instance (Activator.Crea teInstance) of 'dsofile.OleDoc umentProperties Class' it throw the following registry exception:

"Retrieving the COM class factory for component with CLSID {58968145-CF05-4341-995F-2EE093F6ABA3} failed due to the following error: 80040154."

Please help me, how i access file property using dsofile w/o registration in registry. Below are the code that i using, bold line is the cause of above exception:


Assembly dsoFile = Assembly.LoadFi le(baseDirector y + "Interop.DSOFil e.dll");
Type OleDocumentProp ertiesClassType = dsoFile.GetType ("DSOFile.OleDo cumentPropertie sClass");
object OleDocumentProp ertiesClassInst ance = Activator.Creat eInstance(OleDo cumentPropertie sClassType);
MethodInfo OleDocOpenMetho d = OleDocumentProp ertiesClassType .GetMethod("Ope n");

Cheers,

Sanjay

Why don't you want to register the dll in the registry?
I sounds like you are in some way trying to be 'sneaky' when you know that by registering it your problem will be solved.

Thanks for reply,

I know if i registered then it not create me any problem, this is windows application and it will deploying in multiple system. My deployment process is just copy paste nothing else. so i will only copy dsofile on server and it will copy by our syncronization process. By reflection i will direct using the methods of dsofile.dll.

Please let me know if i missed out any code part.. or any alternate way to handle this..
