Dear all,
i am having the following code to impersonate the windows authentication in my winform program. The code runs well for the MS SQL Server login during runtime. But it has the problem to pass the impersonated windows login credential to crystal report viewer.
DimtokenHandle AsNewIntPtr(0)
Try
IfLogonUser("un", "DOMAINNAME", "pw", 2, 0, tokenHandle) Then
DimnewId AsNewWindowsIdentity(tokenHandle)
Using impersonatedUser AsWindowsImpersonationContext = newId.Impersonate()
rpt = New ReportDocument
rpt.Load(Application.StartupPath & "\Reports\appendixB.rpt")
crvPreview.ReportSource = rpt
EndUsing
CloseHandle(tokenHandle)
Else
'logon failed
EndIf
Catchex AsException
'exception
EndTry
when i start the impersonate and want to open the report using crystal report viewer. It gives me the following message. I have confirmed nothing to do with the runtime. As the moment i add the PC user as a SQL server login. Then the report shown.
The impersonated ID during the runtime has the access to the SQL server as well. Hope someone could help
