Hi,

does anybody know how to call a WindowsProgressDialog in a process plugin?

I always get this error: System.InvalidCastException: Specified cast is not valid.

Here is my code:

[code]

Imports MediaPortal.Dialogs

Public Class DialogProgressPlugin

    Implements MediaPortal.GUI.Library.IPlugin, MediaPortal.GUI.Library.ISetupForm

    Public Const WINDOW_DialogProgressPLUGIN = 6202 'a window ID shouldn't be needed when a non visual plugin ?!

    Private EPGTimer As System.Threading.Timer

    Public Sub Start() Implements MediaPortal.GUI.Library.IPlugin.Start

        Dim timerDelegate As System.Threading.TimerCallback = AddressOf WindowsProgressDialog

        EPGTimer = New System.Threading.Timer(timerDelegate, Nothing, 500, 15000)

    End Sub

    Public Sub WindowsProgressDialog(ByVal stateInfo As Object)

        'Create dialog to show progress

        Try

            Dim dlgProgress As MediaPortal.Dialogs.GUIDialogProgress = CType(MediaPortal.GUI.Library.GUIWindowManager.GetWindow(CType(MediaPortal.GUI.Library.GUIWindow.Window.WINDOW_DIALOG_PROGRESS, Integer)), MediaPortal.Dialogs.GUIDialogProgress)

            If (Not dlgProgress Is Nothing) Then

                dlgProgress.SetHeading("DialogHeading")

                dlgProgress.SetLine(1, "DialogLine1")

                dlgProgress.SetLine(2, "DialogLine2")

                dlgProgress.SetLine(3, "DialogLine3")

                dlgProgress.StartModal(MediaPortal.GUI.Library.GUIWindowManager.ActiveWindow)

                dlgProgress.SetPercentage(0)

                dlgProgress.Progress()

                dlgProgress.ShowProgressBar(True)

            End If

            Dim iCounter As Integer = 0

            While iCounter <= 100

                dlgProgress.SetPercentage(iCounter)

                Threading.Thread.Sleep(100)

                iCounter += 1

            End While

            dlgProgress.Close()

        Catch ex As Exception

            MsgBox(ex.ToString)

        End Try

    End Sub

    Public Sub [Stop]() Implements MediaPortal.GUI.Library.IPlugin.Stop

    End Sub

    Public Function Author() As String Implements MediaPortal.GUI.Library.ISetupForm.Author

        Return "STSC"

    End Function

    Public Function CanEnable() As Boolean Implements MediaPortal.GUI.Library.ISetupForm.CanEnable

        Return True

    End Function

    Public Function DefaultEnabled() As Boolean Implements MediaPortal.GUI.Library.ISetupForm.DefaultEnabled

        Return True

    End Function

    Public Function Description() As String Implements MediaPortal.GUI.Library.ISetupForm.Description

        Return "DialogProgress"

    End Function

    Public Function GetHome(ByRef strButtonText As String, ByRef strButtonImage As String, ByRef strButtonImageFocus As String, ByRef strPictureImage As String) As Boolean Implements MediaPortal.GUI.Library.ISetupForm.GetHome

        strButtonText = "DialogProgress"

        strButtonImage = ""

        strButtonImageFocus = ""

        strPictureImage = ""

        Return False

    End Function

    Public Function GetWindowId() As Integer Implements MediaPortal.GUI.Library.ISetupForm.GetWindowId

        Return WINDOW_DialogProgressPLUGIN

    End Function

    Public Function HasSetup() As Boolean Implements MediaPortal.GUI.Library.ISetupForm.HasSetup

        Return False

    End Function

    Public Function PluginName() As String Implements MediaPortal.GUI.Library.ISetupForm.PluginName

        Return "DialogProgress"

    End Function

    Public Sub ShowPlugin() Implements MediaPortal.GUI.Library.ISetupForm.ShowPlugin

        'no setup form, therefore nothing to do

    End Sub

End Class

[/code]

It seeme that this line causes trouble:

What's wrong?

Thanks!!
