asked on How can I speed up running several queries to populate data on a form?
I have a form that I has (4) command buttons. The caption on the command buttons will display the record count of a query. The forms On Current Events runs (4) queries for record counts on each. It takes about 10 seconds to load the form. Is the code correct? Is there a way to speed it up?
Private Sub Form_Current()
Dim rsUpdatesCount As Integer
Dim rsActiveCasesCount As Integer
Dim rsActivitiesCount As Integer
Dim rsTasksCount As Integer
Dim queryNameOrSQL As String
Set db = CurrentDb
queryNameOrSQL = "SELECT * FROM QueryAllUpdates"
Set rs = CurrentDb.OpenRecordset(queryNameOrSQL, dbOpenDynaset, dbSeeChanges)
rs.MoveLast
rsUpdatesCount = rs.RecordCount
Me.CmdUpdates.Caption = "Updates " & rs.RecordCount
' Next Query
queryNameOrSQL = "SELECT * FROM QuerySubActive"
Set rs = CurrentDb.OpenRecordset(queryNameOrSQL, dbOpenDynaset, dbSeeChanges)
rs.MoveLast
rsActiveCasesCount = rs.RecordCount
Me.CmdActiveCases.Caption = "Active Cases " & rs.RecordCount
'Next Query
queryNameOrSQL = "SELECT * FROM QuerySubTasks"
Set rs = CurrentDb.OpenRecordset(queryNameOrSQL, dbOpenDynaset, dbSeeChanges)
rs.MoveLast
rsTasksCount = rs.RecordCount
Me.CmdTask.Caption = "Tasks " & rs.RecordCount
'Next Query
queryNameOrSQL = "SELECT * FROM QuerySubActivity"
Set rs = CurrentDb.OpenRecordset(queryNameOrSQL, dbOpenDynaset, dbSeeChanges)
If Not (rs.BOF And rs.EOF) Then
rs.MoveLast
rsActivitiesCount = rs.RecordCount
Me.CmdActivity.Caption = "Activities " & rs.RecordCount
Else
End If
rs.Close
Set rs = Nothing
End Sub

private function ButtonCount(byval pstrTitle as String, byval pstrKey as String, byval pstrSQL as string) as String
ButtonCount = pstrTitle & " " & format(nz(Dcount(pstrKey, pstrSQL),0))
end function
then your code looks like
me.cmdUpdates.Caption = ButtonCount("Updates", "YourKeyField", "QueryAllUpdates")
me.cmdActiveCase.Caption = ButtonCount("Active Cases", "KeyField", "QuerySubActive")
etc.
