I'm not sure exactly how to describe this. In VB6, there was a Timer command. I could create a variable of type Timer and loop until the current value for Timer exceeded the initial plus a given amount of time. This allowed me to update form variables while the timing loop was executing. How can I do something similar in .NET?

Here is a sample of the VB6 code:

CODE
    Dim StartTimer As Double

    StartTimer = Timer
    Do

        Call Sleep(100)
        txtFinalRefValue.Text = DVMread(SystemSetup.RefChannel)
        
    Loop While (Timer < (StartTimer + LeakTestTime)) And DoEvents()

I believe what you are looking for is:

CODE

Application.DoEvents()

I guess I just didn't realize that the Timer function still existed in .NET. Here's the final code...

CODE

     Dim StartTimer As Double
     Dim LeakTestTime As Double = 5

     StartTimer = DateAndTime.Timer
     Do

        Threading.Thread.Sleep(100)
        txtFinalRefValue.Text = DVMread(SystemSetup.RefChannel)
        Application.DoEvents()
     Loop While (DateAndTime.Timer < (StartTimer + LeakTestTime))
