Steps to Create a Stopwatch Form

Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. The following example demonstrates how to create and how to use a form to track elapsed time:
  1. Open any database.
  2. Create a blank form not based on any table or any query and then set the following properties for the form:
       ScrollBars: Neither   RecordSelectors: No   NavigationButtons: No   OnTimer: [Event Procedure]   TimerInterval: 0					
  3. Add a text box to the form and then set the following properties for the text box:
       Name: ElapsedTime   DefaultValue: "00:00:00:00"   Enabled: No   Locked: Yes					
  4. Add a command button to the form and then set the following properties for the command button:
       Name: btnStartStop   Caption: Start   OnClick: [Event Procedure]					
  5. Add a second command button to the form and then set the following properties for the second command button:
       Name: btnReset   Caption: Reset   OnClick: [Event Procedure]					
  6. Click Code on the View menu to open the editor. Type the following lines in the Declarations section:
    Option ExplicitDim TotalElapsedMilliSec As LongDim StartTickCount As LongPrivate Declare Function GetTickCount Lib "kernel32" () As Long					
  7. Set the OnTimer property of the form to the following event procedure:
    Private Sub Form_Timer ()   Dim Hours As String   Dim Minutes As String   Dim Seconds As String   Dim MilliSec As String   Dim Msg As String   Dim ElapsedMilliSec As Long   ElapsedMilliSec = (GetTickCount() - StartTickCount) + _      TotalElapsedMilliSec   Hours = Format((ElapsedMilliSec \ 3600000), "00")   Minutes = Format((ElapsedMilliSec \ 60000) Mod 60, "00")   Seconds = Format((ElapsedMilliSec \ 1000) Mod 60, "00")   MilliSec = Format((ElapsedMilliSec Mod 1000) \ 10, "00")   Me!ElapsedTime = Hours & ":" & Minutes & ":" & Seconds & ":" _      & MilliSecEnd Sub					
  8. Set the OnClick property of the btnStartStop command button to the following event procedure:
    Private Sub btnStartStop_Click()   If Me.TimerInterval = 0 Then      StartTickCount = GetTickCount()      Me.TimerInterval = 15      Me!btnStartStop.Caption = "Stop"      Me!btnReset.Enabled = False   Else      TotalElapsedMilliSec = TotalElapsedMilliSec + _         (GetTickCount() - StartTickCount)      Me.TimerInterval = 0      Me!btnStartStop.Caption = "Start"      Me!btnReset.Enabled = True   End IfEnd Sub					
  9. Set the OnClick property of the btnReset command button to the following event procedure:
    Private Sub btnReset_Click()   TotalElapsedMilliSec = 0   Me!ElapsedTime = "00:00:00:00"End Sub					
  10. Open the form in Form view to test the stopwatch.
