I am new to Rightfax and working with Rightfax COM API in vb.net. I added a right fax reference in   my project.

1.Private Shared rfapi As RFCOMAPILib.FaxServer

2. rfapi = New RFCOMAPILib.FaxServer

 I am getting following  error in second line

Creating an instance of the COM component with CLSID {D7CA3941-DA83-4C87-949A-60DF378DD68E} from the IClassFactory failed due to the following error: 80070485

What is this error. Is it because of Com Libraury licence error?

thanks

The CLSID error is due to the API dll not being registered on the system. You should not run into the problem of needing to register the dll's on the actual RightFax server, as they are registered during the server installation process; but when developing on another system, these files need to be manually registered.

You need to run regsvr32 to register the RFCOMAPI.dll. In addition the following files need to be in the same directory as RFCOMAPI.dll:

RFI32RPC.ndr

RFI32smb.ndr

rfstat.dll

rfwin32.dll

Erin

copy Rfi32smb.ndr,rfwin32.dllmrfcomapi.dll   ,Rfi32rpc.ndr

above 4 files to the complus directory or where your dll sitting, it will solve the problem.
