Create workspace error (object is not a valid page) in asp.net project

sabeena_12

Hi,

I'm using visual studio 2005 to create a 'simple' web application which can create workspaces on the fly. I've added the imanage.dll reference and everything seems to work fine until I get to the "objWorkspace.Update()" method. At this point I receive the following error:
"[Folder][Update]Object is not a valid page"

This is the code I've been using:
IManWorkspace objWorkspace;
ManDMS objDMS = new ManDMS();
ManStrings objManStrings = new ManStrings();

IManSession objSession = objDMS.Sessions.Add(strDMS);
objSession.Login(strUser, strPassword);

IManDatabase objDB = objSession.Databases.ItemByName(strDB);
objWorkspace = objDB.CreateWorkspace();
objWorkspace.Owner = objDB.GetUser("SMITHJ");
objWorkspace.Name = "zzz - Workspace";
objWorkspace.Description = "Workspace";
objWorkspace.Security.DefaultVisibility = imSecurityType.imView;
objWorkspace.Security.UserACLs.Add("SMITHJ", imAccessRight.imRightAll);
objWorkspace.SubType = "WORK";

string strFilePath = Path.GetTempFileName();

objWorkspace.Update(); [ERROR HAPPENS HERE!!]
objSession.Logout();

I'm hoping there's a really simple resolution to this, but as I've been trying to figure it out for ages now and haven't got anywhere, thought it best to ask for help!

Any ideas would be greatly appreciated.

Thanks,
