MOD2000: Only One Record Returned When You Change Data Control SQL Statement

• Microsoft Office 2000 Developer

SYMPTOMS

After you change the CommandText property of a Microsoft ADO data control, the control returns only one record, regardless of how many records the modified SQL statement should return.

RESOLUTION

In your Visual Basic for Applications code, refresh the data control before you bind additional controls to it, for example:

'In this example the control Adodc1 is refreshed before data source 
'for the data grid is set.
Private Sub CommandButton1_Click()
   Adodc1.Refresh
   Set DataGrid1.DataSource = Adodc1
End Sub 

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.
