My goal is to write the volume value from XML and convert it from string to integer

but at this line interpreter returns error: "Input string was not in a correct format"
Code:
dim WhatISVolumeInt as integer = Convert.toInt32(WhatISVolumeComma)


replacing a period with a comma nor convert to a double does not help

Code:
dim xml as string = API.XML()
dim x as new system.xml.xmldocument
x.loadxml(xml)

dim WhatISVolume as string = (x.SelectSingleNode("//input[@title='Music']/@volume").Value)

dim WhatISVolumeComma as string = ""

If WhatISVolume.Contains(".") Then
    WhatISVolumeComma = WhatISVolume.Replace(".", ",")
End If

dim WhatISVolumeInt as integer = Convert.toInt32(WhatISVolumeComma)

for i as integer = 0 to WhatISVolumeInt
             API.Function("SetVolume",Input:="Music",Value:=WhatISVolumeInt)
             WhatISVolumeInt = WhatISVolumeInt-1
sleep(8)
next


and yes, I know about SetVolumeFade function =)

In case this might help (not sure what you're trying to do)

Quote:
The Volume level in vMix is linked to amplitude and scales with the following formula:

Volume = 0 to 100 (used for UI volume bars)
Amplitude = 0 to 1 (used for API Meter and Volume values)
Decibels = 0 dB to -infinity

Volume = (Amplitude ^ 0.25) * 100
Amplitude = (Volume / 100) ^ 4

Example
VolumeBar = 50
Amplitude = 0.0625
MeterF = 0.0625
VolumeXML = 6.25

P.S meter values in XML are in Amplitude 0-1, while volume values in XML are in Amplitude 0-100

Line 13 of your code contains the variable WhatISVolumeInt twice. Doesn't seem right.

Amplitude is not available from API, MeterF is current level value, not Volume

typo, corrected

this way it does not works too
Code:
dim WhatISVolumeInt as integer = Convert.toInt32(WhatISVolumeComma)

Not sure what you are getting at , seems you want the value before the period to return as a single integer ?

Code:
Dim IWant = Convert.ToInt32(WhatISVolume.Split("."c)(0))


or

Code:
Console.WriteLine(Math.Ceiling(Convert.ToDecimal(WhatISVolume )))
Console.WriteLine(Math.Floor(Convert.ToDecimal(WhatISVolume )))
Console.WriteLine(Math.Round(Convert.ToDecimal(WhatISVolume )))

Yes, value before period was solution:

Code:
dim xml as string = API.XML()
dim x as new system.xml.xmldocument
x.loadxml(xml)

dim WhatISVolume as string = (x.SelectSingleNode("//input[@title='Music']/@volume").Value)

Dim WhatISVolumeComma as string = WhatISVolume

If WhatISVolume.Contains(".") Then
   WhatISVolumeComma = WhatISVolume.Substring(0, WhatISVolume.IndexOf("."))
End If

dim WhatISVolumeInt as integer = Convert.toInt32(WhatISVolumeComma)

for i as integer = 0 to WhatISVolumeInt
             API.Function("SetVolume",Input:="Music",Value:=WhatISVolumeInt)
             WhatISVolumeInt = WhatISVolumeInt-1
sleep(8)
next


Thank you!

Does VBscript have support for locales? I've written code in the past which assumed decimal values would include a period, which of course failed the first time it encountered input from a different locale where commas are used as the decimal separator. Just curious how VBscript deals with that.
