Variable Not Being Set.. - Resolved

[Pino]

Ok i'm working on a Web Cam Class to get me going in .Net really.

I've hit a slight problem, when the user starts previewing the camera and all goes succesful I set a boolean variable to True (IRunning) so that if they click start again the routine will exit if iRunning is true. For some strange reason this isnt happening, i've spent an hour or so playing with it, here is the code.. and i've attacthed the app incase you need it.

Public Sub initCam(ByVal parentH As Integer)
        frmViewer = New frmMain
        MessageBox.Show(Me.iRunning) 'dubug purpose
 
        If Me.iRunning = True Then 'not working....
            MessageBox.Show("Camera Is Already Running")
            Exit Sub
        Else
 
            hHwnd = capCreateCaptureWindowA(iDevice, WS_VISIBLE Or WS_CHILD, 0, 0, 480, 360, parentH, 0)
 
 
            If setCam() = False Then
                MessageBox.Show("Error setting Up Camera")
            End If
        End If
    End Sub
 
 
    Private Function setCam() As Boolean
        If SendMessage(hHwnd, WM_CAP_DRIVER_CONNECT, iDevice, 0) Then
            SendMessage(hHwnd, WM_CAP_SET_PREVIEWRATE, CamFrameRate, 0)
            SendMessage(hHwnd, WM_CAP_SET_PREVIEW, True, 0)
            Me.iRunning = True ' here set to true....
            Return True
        Else
            Me.iRunning = False
            Return False
        End If
    End Function

Any help or guidence on this? am i using variables incorrectly?
