How to: Use the Status Bar Progress Meter
This topic shows how to use the SysCmd method to create a progress meter on the status bar that gives a visual representation of the progress of an operation that has a known duration or number of steps.
There are three intrinsic constants that can be used with the SysCmd method's action argument to manipulate the progress meter on the status bar. The following table describes them.
Intrinsic constant |
Description |
---|---|
acSysCmdInitMeter |
Initialize the progress meter. The maximum value that the process will attain is specifed in the SysCmd method's value argument. |
acSysCmdUpdateMeter |
Update the progress meter. A numeric expression that represents the current progress toward completion is specified in the SysCmd method's value argument. |
acSysCmdRemoveMeter |
Remove progress meter. |
The following procedure uses the SysCmd method to update the progress meter as data from the Customers table is printed in the Immediate window.
Sub ProgressMeter()
Dim MyDB As DAO.Database, MyTable As DAO.Recordset
Dim Count As Long
Dim Progress_Amount As Integer
Set MyDB = CurrentDb()
Set MyTable = MyDB.OpenRecordset("Customers")
' Move to last record of the table to get the total number of records.
MyTable.MoveLast
Count = MyTable.RecordCount
' Move back to first record.
MyTable.MoveFirst
' Initialize the progress meter.
SysCmd acSysCmdInitMeter, "Reading Data...", Count
' Enumerate through all the records.
For Progress_Amount = 1 To Count
' Update the progress meter.
SysCmd acSysCmdUpdateMeter, Progress_Amount
'Print the contact name and number of orders in the Immediate window.
Debug.Print MyTable![ContactName]; _
DCount("[OrderID]", "Orders", "[CustomerID]='" & MyTable![CustomerID] & "'")
' Go to the next record.
MyTable.MoveNext
Next Progress_Amount
' Remove the progress meter.
SysCmd acSysCmdRemoveMeter
End Sub
