Excel process thread hiJacks KeyBoard strokes RRS feed

  • Question

  • Hi Team,

    We have a Developed a VSTO Add-In (Excel Add-In) Application with couple of Buttons in the Ribbon.

    On Starting/launching the Application, It launches excel Instance. On the Button Click We are instantiating the WPF window having some Input Textboxes for the user to Enter the Values.

    The Issue here is When we try to type in the Textboxes, It types it in the Excel window.

    The Wpf window runs under the same process of the Add-In which is (Excel Process).

    could you please suggest a solution foe this issue.

  • Hello Amol,

    What code do you use for displaying your WPF window?

    Did you try to use Windows form controls instead to implement the task?

            public ShellWindowView EnquiryManagerClient
                    if (_enquiryManagerClient == null)
                        _enquiryManagerClient = new ShellWindowView(Globals.ThisAddIn.Application, "QuoteViewModel");
                        _enquiryManagerClient.Closing += EnquiryManagerClientOnClosing;
                    return _enquiryManagerClient;
    private void btnEnquiryManager_Click(object sender, RibbonControlEventArgs e)
                ClickedButton = sender as Microsoft.Office.Tools.Ribbon.RibbonButton;

    Hi Eugene,

    Thanks for the reply.

    I have put in the code above.

    btnEnquiryManager --> a button on the Ribbon

    "QuoteViewModel" --> A Wpf View to be opened on Click of Ribbon button

    EnquiryManagerClient --> A property which instantiate the Wpf window object.

    We have been using MVVM with WPF & not the Windows Forms. Please let me know if you need any other information

  • I'd suggest running a Windows form instead. Or you can try to place your WPF controls on the Windows form. Does it work as expected?
