QTP script to Add defect in QC

Hi ,
Most of us would be familiar with logging defects in Quality Center manually.
How about Adding a defect using a QTP script?
Here we go !!!
Script :
Set TDConnection = CreateObject(”TDApiOle.TDConnection”)
TDConnection.InitConnection “http://yovav/tdbin” ‘ DB URL
TDConnection.ConnectProject “TD76″,”bella”,”pino” ‘ Valid login information
If TDConnection.Connected Then
MsgBox(”Connected to ” + chr (13) + “Server ” + TDConnection.ServerName _+ chr (13) +”Project ” + TDConnection.ProjectName )
Else
MsgBox(”Not Connected”)
End If

‘Get the IBugFactory
Set BugFactory = TDConnection.BugFactory
‘Add a new empty bug
Set Bug = BugFactory.AddItem (Nothing)
‘fill the bug with relevant parametersBug.Status = “New”
Bug.Summary = “Connecting to TD”
Bug.Priority = “4-Very High” ‘ depends on the DB
Bug.AssignedTo = “admin” ‘ user that must exist in the DB’s users list
Bug.DetectedBy = “admin” ‘ user that must exist in the DB’s users list
‘Post the bug to DB ( commit )
Bug.Post
