Okay, I need to programmatically enclose a string in quotation marks. When I'm writing vb.Net apps this is usually by appending Chr(34) to each end. But for some odd reason, vMix's script interpreter has no idea what Chr(34) is, nor Strings.Chr(34).

Ideas or alternate methods?

Line 13 below. Passing arguments to a cmd.exe...

Code:

'Configure webcams

	Console.WriteLine(Microsoft.VisualBasic.Strings.Format(DateTime.Now(),"HH:mm:ss") & " |     Configuring webcams...")

	ExtProcessParams = New Diagnostics.ProcessStartInfo

	ExtProcessParams.FileName = "cmd.exe"
	ExtProcessParams.CreateNoWindow = true
	ExtProcessParams.UseShellExecute = false
	ExtProcessParams.RedirectStandardError = true
	ExtProcessParams.RedirectStandardOutput = true
	ExtProcessParams.Arguments = "/c " & Chr(34) & "C:\Program Files (x86)\CamSet\ConfigureWebcams.cmd" & Chr(34)
	ExtProcess = Diagnostics.Process.Start(ExtProcessParams)
	ExtProcess.WaitForExit()
	
	ExtProcessResult = ExtProcess.StandardOutput.ReadToEnd()
	ExtProcessError = ExtProcess.StandardError.ReadToEnd()
	
	If Not ExtProcess.ExitCode = 0 Then
		Console.WriteLine(Microsoft.VisualBasic.Strings.Format(DateTime.Now(),"HH:mm:ss") & " |         Configuring webcams failed.")
		Console.WriteLine(Microsoft.VisualBasic.Strings.Format(DateTime.Now(),"HH:mm:ss") & " |             " & ExtProcessResult)
		Console.WriteLine(Microsoft.VisualBasic.Strings.Format(DateTime.Now(),"HH:mm:ss") & " |             " & ExtProcessError)
	End If
	
	ExtProcessResult = ""
	ExtProcessError = ""
	ExtProcessParams = Nothing
	ExtProcess = Nothing

Well I'll be damned - all the years I've been writing vb.net stuff, and the only way I knew to do this was appending character codes. I had no idea you could escape quotes with....more quotes in .Net.

I guess using Chr(34) is a habit I picked up in VB6 and it worked in .Net too, so I never changed.

I searched earlier too, but I searched "CHR(34) alternative" then ran out of time before digging deeper.

Thanks doggy.
