[RESOLVED] [2008] Updating Form Variables during Thread

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()

---

Code:

---

Loop While (Timer < (StartTimer + LeakTestTime)) ' And DoEvents()

---

Remove the DoEvents() from the loop, and it should work. That's not exactly the best way to do that.


You can have a separate thread that updates a textbox separately from the main thread. They both run at once, but one doesn't hold back the other, like DoEvents would. (10x per second!)

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))
