Trouble getting device configuration

[svenvanhees]

Hello,

I have trouble using the GetDeviceConfig function. From within my app I would like the user to permanently change settings for a specific tapi line without going to the control panel an searching for the tsp provider.

I have a sub with the following:

Public Shared Sub OpenConfigDialog()

        ' Get the current active tapi line
        Dim ActiveTapiLine As TapiLine = GetActiveTapiLine()

        ' Open the config dialog for the line
        ActiveTapiLine.Config(Nothing, "tapi/line")

        ' Get the config as byteArray
        Dim LineConfigByteArray As Byte() = ActiveTapiLine.GetDeviceConfig("tapi/line")

        ' Store updated config as byteArray
        ActiveTapiLine.SetDeviceConfig("tapi/line", LineConfigByteArray)

End Sub

The problem is that the GetDeviceConfig returns {Length=0}. However, I expect that to return an updated config so it can be used again with the SetDeviceConfig function.

Am I doing something wrong? Hope you can help.
