DataGrid + ador.recordset is showing 0 recordcount

Have you tried
rDis.Movefirst (placed immediatly after rDis.Update?

Thanks for the reply.  Yes I have tried all variations of moving through the recordset including this:

While Not rDis.EOF     '=FALSE or true with the negate
        Debug.Print rDis.Fields(0).Value   '=Shows a Value
        rDis.MoveNext
Wend
debug.print rDis.recordCount    '=Still shows 0 even though I watched it move through.

Thanks for your time

Is this a server side recordset or client. What type of cursor are you using

Extracted from the VB help file

Use the RecordCount property to find out how many records are in a Recordset object. The property returns -1 when ADO cannot determine the number of records or if the provider or cursor type does not support RecordCount. Reading the RecordCount property on a closed Recordset causes an error.

If the Recordset object supports approximate positioning or bookmarks—that is, Supports (adApproxPosition) or Supports (adBookmark), respectively, return True—this value will be the exact number of records in the Recordset regardless of whether it has been fully populated. If the Recordset object does not support approximate positioning, this property may be a significant drain on resources because all records will have to be retrieved and counted to return an accurate RecordCount value.

The cursor type of the Recordset object affects whether the number of records can be determined. The RecordCount property will return -1 for a forward-only cursor, the actual count for a static or keyset cursor, and either -1 or the actual count, depending on the data source, for a dynamic cursor.

The cursor is set up like this:

    rDis.CursorType = adOpenDynamic
    rDis.CursorLocation = adUseClient

The issue is the first time a user adds a record everything works fine (RecordCount goes to 1).  If the user has deleted all of the records through the datagrid the RecordCount goes to 0.  At this point everything changes.  When adding a record the same way that it is added in the beginning the recordCount is never incremented.

Thanks for your time.

The adUseClient setting should be OK. Have you tried changing adOpenDynamic to either static or keyset, suggest trying that first.

Failing that could you show me the entire sub routine that picks up the recordcount value.

Tried different settings with no sucess.

When the project loads the recordset is set like this:
    Set rDis = New ADOR.Recordset
    rDis.Fields.Append "MySQL", adVarChar, 100
    rDis.Fields.Append "ACT!", adVarChar, 100
    rDis.Fields.Append "aID", adInteger
    rDis.CursorType = adOpenStatic
    rDis.CursorLocation = adUseClient
    rDis.Open
    Set Start.dgMaps.DataSource = rDis        'START IS THE NAME OF THE FORM
    Start.dgMaps.Columns(2).Visible = False

This is the sub that is picking the recordcount value.  The idea is to not allow duplicate entries in the datagrid/recordset:

Private Sub cmdMap_Click()
 Dim bgood As Boolean
 Dim sSQL As String
 bgood = False
 Debug.Print rDis.RecordCount
 If bHaveMaps Then
    If rDis.RecordCount > 0 Then
   
        rDis.MoveFirst
        While Not rDis.EOF
            If rDis.Fields(0).Value = Trim(Left(txtMapS.Text, (InStr(txtMapS, "(") - 1))) And _
                rDis.Fields(1).Value = Trim(Left(txtMapA.Text, (InStr(txtMapA, "(") - 1))) Then
                cmdMap.Enabled = False
                Exit Sub
            End If
        rDis.MoveNext
        Wend
    End If
    If checkTable Then
        bgood = True
    Else
        MsgBox "Please Choose fields from a single table only", vbInformation, "Table Conflict"
        bgood = False
    End If
Else
    bgood = True
End If
If bgood Then
    rDis.AddNew
    rDis.Fields(0).Value = Trim(Left(txtMapS.Text, (InStr(txtMapS, "(") - 1)))
    rDis.Fields(1).Value = Trim(Left(txtMapA.Text, (InStr(txtMapA, "(") - 1)))
    rDis.Fields(2).Value = (Left(sStageKeyACT, (InStr(sStageKeyACT, "%") - 1)))
    rDis.Update
    Debug.Print rDis.RecordCount
    sCurrentTableSQL = sStageTableSQl
    sCurrentTableACT = sStageTableACT
    If Not bHaveMaps Then bHaveMaps = True
    If Not bDirty Then bDirty = True
End If

End Sub

Thanks for your time.

Just a suggestion - try placing a Debug.Print rDis.RecordCount after  rDis.MoveFirst in the Private Sub cmdMap_Click().

It makes no difference.  I can add mutiple records but the recordcount is never changed until I manualy delete a row from the datagrid.

Thanks for your time.

Have you checked for an error condition whilst running this routine? ie from within VB

Select Tools
Select Options
Select General
Set error trapping to Break on all errors

Then run the routine and see if you get an error generated.

I'm just trying to determine if a null field value is causing your problem.

Thanks for the suggestion.  It does not generate an error.  It is like this: When the program is first run the recordcount = 0 as the user adds items it goes up and as the user deletes items it goes down.  If the user takes out all of the items it goes to zero.  At that point if the user adds an item the item is processed and shows in the grid but the recordcount does not reflect it. No matter how many items are added the recordcount stays at zero.  If the user deletes one of the rows the recordcount magically is restored.

Thanks for your time.

Thanks for your time and help here is how I am dealing with the bug:
   
    I add the real record then update
    rDis.Update
    If rDis.RecordCount = 0 Then 'clunky fix for bug
        With rDis
            .AddNew
            .Fields(0) = "squib"
            .Update
            .Delete adAffectCurrent
        End With
    End If
    Debug.Print rDis.RecordCount  'This will now read 1

This seems to work fine although it is funky.

Not ideal - but if it works .....

Hi

What version of ADO are you using 2.6?
Anyway you could try this one liner before querying record count:

adoRs.Filter = ADODB.FilterGroupEnum.adFilterNone

Then query the record count, this will update the record count and also move the cursor to the either BOF or the first row.

Also define the recordset as adUseClient and KeySet.

Give it a whizz

Thanks

I tried your solution but it had no effect.

I have asked for a refund of points and that this question be closed.  If you read the above you will see that I found a funky solution that worked for me and used it to solve my problem.  

Thank you to everyone that offered sugestions.
