XL5: Screen Updated Incorrectly with SQLRetrieve Function

ID: Q134614


The information in this article applies to:
  • Microsoft Excel for Windows, version 5.0


SYMPTOMS

In Microsoft Excel, the screen does not appear to be updated as expected when you are using the SQLRetrieve macro function to fetch data.


CAUSE

In Microsoft Excel version 5.0, the results are returned essentially by pasting the data to the Microsoft Excel spreadsheet. However, in Microsoft Excel version 5.0c, a faster method of returning data is used to populate the spreadsheet with the data.


RESOLUTION

To avoid this problem, use the ScreenUpdating property of the Application object. When this property is set to False, the screen is not updated until the macro stops or the property is set back to True. The following macro example illustrates this workaround:


Sub SQLRetrieve_Example()
   ' Open a channel to the Nwind data source.
   chan = SQLOpen("DSN=Nwind 2.0")

   ' Execute a query to return all records from the Employee table.
   SQLExecQuery chan, "SELECT * FROM employee"

   ' Retrieves the first record to the buffer.
   SQLRetrieve chan, ActiveCell, 2, 1, False, False, True, True

   ' Turn off screen updating.
   Application.ScreenUpdating = False

   ' Loop through the current data set and return one row at a time.
   For x = 1 To 20
       SQLRetrieve chan, ActiveCell.Offset(x, 0), 2, 1, _
          False, False, True, False
   Next

   ' Close the channel to Nwind.
   SQLclose chan

   ' Turn on screen updating.
   Application.ScreenUpdating = True
End Sub
