Terminal progressbar in vbs vbscript

This is a progressbar. The script is run with cscript.

progtressMax is defined outside the function and is global. For instance 30.
Function DisplayProgress(progressNumber)
	On Error Resume Next
	Dim percentDone, percentLeft, intCount
	'oShell.SendKeys "CLS + {ENTER}" 
	oShell.Run "cls" 
	progressCount = progressCount + progressNumber
	wScript.StdOut.Write("|")
	percentDone = round((progressCount / progressMax) * 100)
	For intCount = 0 To percentDone
		wScript.StdOut.Write(".")
	Next
	percentLeft = round(100-((progressCount / progressMax) * 100))
	For intCount = 0 To percentLeft
		wScript.StdOut.Write("_")
	Next
	wScript.StdOut.Write("|")
End Function

Open in new window


The problem is that I am not able to clear the screen at the start of the function. So the progressbar floods the screen without making any sense.

Is there a better way to make a terminal progressbar? I don't want html and I don't want popups. Is there a way that works to clear the screen? Please don't post links to other pages of code unless you have tested and verified that it works. The above code for clearing does not work, and there are several examples out there of code that does not work.

You don't actually need to clear the screen between every update, just move the cursor back to the beginning of the line.  

Remove the "cls" line (not needed).
Replace line 7 above with:
      wScript.StdOut.Write chr(13) + "|"

Do note that the terminal is only 80 characters wide by default, so you may need to do some extra math to make the maximum width of the bar fit in the window.
