Hi everyone,I am trying open and read Dgn file. But, I got the error "Error HRESULT E_FAIL has been returned from a call to a COM component ?" when using below codes:
IWorkspaceFactory factory = new CadWorkspaceFactoryClass ();
IWorkspace workspace = factory.OpenFromFile(fileName, 0); // Throw exception
May you help me fix this ?Thanks and regards,Tai
