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?

How are you declaring the IsRunning variable?

[Pino]

Public iRunning As Boolean

Is this wrong?

[wossname]

No I was just wonderig if you had set an initial value to it at the same time. Never mind

In your button click routine you are reinstantiating the mycam variable each time. That might be part of the problem.

:-p how could i be so stupid.....

I havent tested it but i think your right....

I'm seting myCam as new iCam each time the button is clicked....

edit- YAY it works!

Thanks
