hiya--

i am trying to run this code that i found on the micrsoft support site.

HOWTO: Work Around the Limitation that ADO MaxRecord Is Not Implemented in DS OLEDB Provider ADsDSOObject (Q269361)

http://support.microsoft.com/default.aspx?scid=kb;EN-US;q269361


it is supposed to connect to the exhange server (ldap) and pull peoples information out.

when the number of results is low (anything 80 and under so far) it seems to work. however, when i try to pull info when the user name is smith (about 530 results)
i get this error:

Data provider or other service returned an E_FAIL status.

Microsoft Cursor Engine


my code is listed below. im gonna keep digging but any help would be great.

thanks --p

1. you need to use ado 2.5, 2.6 has bud you can search support.microsoft.com

2. you should try use command object because rs has some problems :


Private Function mfGetActiveDirectoryData(ByVal lvsLetter As String) As ADODB.Recordset
 
 
  Dim ljrsAD As ADODB.Recordset
  Dim ljcmAD As ADODB.Command
 
  Dim lvsADQuery As String
  Dim lvsWhere As String
 
  On Error GoTo Error_
 
  lvsWhere = UCase(lvsLetter) & "*"
 
 
  Call msOpenConnectionAD
  Set ljcmAD = New ADODB.Command
  Set ljcmAD.ActiveConnection = mjcnAD
  ljcmAD.Properties("Page Size") = 100
 
 
    'Alias:    samAccountName
    'First Name: givenname
    'Last Name:  sn
    'Phone Number: TelephoneNumber
    'Department: Department
    'Suite extensionAttribute8
    'city I
    'zip:    postalcode
    'state:    st
    'Address streetaddress
    'Title:    Title
    'Assisant: assistant
    'Company : Company
    'Office: physicalDeliveryOfficeName
  lvsADQuery = gcsADServer & _
  ";(&(objectClass=user)(objectCategory=person)(sn=" & lvsWhere & "));" & _
  "sn,givenName,msExchHideFromAddressLists,samAccountName,mail,telephoneNumber,department,extensionAttribute8,streetaddress,l,postalcode,st,title,assistant,physicalDeliveryOfficeName,Company;subtree"
 
  ljcmAD.CommandText = lvsADQuery
  ljcmAD.CommandTimeout = 3000
  Set ljrsAD = New ADODB.Recordset
  ljrsAD.CursorLocation = adUseClient
   
  'due to the bug with AD we must use command object to execute call
  'or result set will be limited to the first 1000 rows
  ljrsAD.Open ljcmAD, , adOpenStatic, adLockReadOnly, adAsyncExecute
 
  Do While ljrsAD.State = adStateExecuting
    Call Wait
    DoEvents
  Loop
 
  Set ljrsAD.ActiveConnection = Nothing
  Set ljcmAD = Nothing
 
  Call msCloseConnectionAD(geShowError)
 
  ljrsAD.Save AppPath & CurrentDateFolder & "AD_" & lvsLetter & ".rs"
  Set mfGetActiveDirectoryData = ljrsAD
 
Exit_:
  Call AppendToLog("  - " & lvsLetter & " Downloaded rows : " & ljrsAD.RecordCount, awpProcess, True)
  Exit Function

Error_:
  'catch error
  Dim luError As guError
  luError = ErrorToUDT
 
  Call msCloseConnectionAD(geHideError)
  Call ForwardError(luError, mfErrorSource("mfGetActiveDirectoryData"))
 
End Function

Call Wait - it just to keep cpu at low level

in the module :

Private Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)

Public Function Wait(Optional ByVal lvlMilliseconds As Long = 1000)
  Call Sleep(lvlMilliseconds)
End Function

Const SERVER = "<GC://USA0875MS1:389>"

it opens fine now, however, i am getting an "uspecified error" in the wait, doevent loop.

yea, the status turns to "Unspecified error" the second time thru the loop.

 


        Do While ljrsAD.State = adStateExecuting
            Call Wait
            DoEvents
        Loop
