SUMMARY
In Microsoft Visual Basic for Applications, you can time procedures, statements, and functions by typing the Timer function before and after the statements that you want to time.



MORE INFORMATION
The Visual Basic Timer function can be used to record the starting and ending times for a series of commands. The following example sets the variable StartTime to the current system time, runs the code to be timed, and then sets the variable EndTime to the current system time. Finally, the elapsed time between StartTime and EndTime is printed to the debug window using the Debug.Print command.

Visual Basic Sample Code
Sub ElapsedTime Dim StartTime As Double, EndTime As Double

'Stores start time in variable "StartTime" StartTime = Timer

'Place your code to be timed here

'Stores end time in variable "EndTime" EndTime = Timer

'Prints execution time in the debug window Debug.Print "Execution time in seconds: ", EndTime - StartTime End Sub After you run the ElapsedTime macro, you can see the elapsed time in the Immediate pane of the Debug window. To view the Immediate pane of the Debug window, click Debug Window on the View menu.

The following Visual Basic macro creates a text file containing a list of error messages that can be generated in Visual Basic for Applications. The amount of time it takes to accomplish this procedure is displayed in a message box.

Visual Basic Sample Code
Sub ErrorCodes Dim StartTime As Double, EndTime As Double, X

'creates a file of error messages StartTime = Timer 'Stores start time in variable "StartTime"

Open "vbaerror.txt" For Output As #1

For X = 1 To 3300 Print #1, X, Error$(X) Next X

Close #1

EndTime = Timer 'Stores end time in variable "endTime"

'Shows Message Box with elapsed time MsgBox "Execution time in seconds: " + Format$(EndTime - StartTime) End Sub
