How to Select OPOS Device with TextBox Value RRS feed

  • Question

  • I have two Forms

    Main and Control Panel

    I have a line display code in Main form and I have some textboxes on Control Panel Form

    I am trying to get the value of the textbox on control panel form, so it will connect to the line display

    But under createinstance (device)   , it throws a NULL Error.

    explorer = New PosExplorer(Me)

            Dim device As DeviceInfo = explorer.GetDevice(ControlPanel.OPOSLineDisplay.Text)

            POSDisplay = explorer.CreateInstance(device)

  • Hi Jcharles,

    You can also try to access the text box from Form.

    So you can try 

    Me.textbox1.text

    when you just drag the button from toolbox to a tabpage in the tabControl.

    If you add it from this kind of code:

            Dim ButtonTest As Button = New Button()
            ButtonTest.Name = "ButtonTest"
            ButtonTest.Text = "ButtonTest"
            TabControl1.TabPages(0).Controls.Add(ButtonTest)

    then, you can access it like this:

    Console.WriteLine(TabControl1.TabPages(0).Controls("ButtonTest").Text)

    I hope this will be helpful.

    Best regards,
