Question

Hi

The change event is occured once the visio program launched the first time. After this, the user open another visio document,  the change event is not occured. But I test in word and it is OK

Code Snippet:

Office.CommandBar myCommandBar = null;
Office.CommandBarComboBox ComboBox = null;
private void ThisAddIn_Startup(object sender, System.EventArgs e)
{
    this.Application.WindowActivated += new Visio.EApplication_WindowActivatedEventHandler(Application_WindowActivated);
    myCommandBar = this.Application.CommandBars.Add("Test", Office.MsoBarPosition.msoBarTop, false, true);
    myCommandBar.Visible = true;
    ComboBox = this.myCommandBar.Controls.Add(Office.MsoControlType.msoControlComboBox, missing, missing, missing, true) as Office.CommandBarComboBox;
    ComboBox.AddItem("ComboBoxItem1", 1);
    ComboBox.AddItem("ComboBoxItem2", 2);
    ComboBox.Caption = "My ComboBox";
    ComboBox.Tag = "myComboBox";
    ComboBox.Change += new Microsoft.Office.Core._CommandBarComboBoxEvents_ChangeEventHandler(ComboBox_Change);
}
void Application_WindowActivated(Visio.Window Window)
{
    System.Runtime.InteropServices.Marshal.ReleaseComObject(ComboBox);
    ComboBox = null;
    Office.CommandBar bar = this.Application.CommandBars["Test"];
    ComboBox = bar.FindControl(Type.Missing, Type.Missing, "myComboBox", Type.Missing, Type.Missing) as Office.CommandBarComboBox;
    ComboBox.Change += new Microsoft.Office.Core._CommandBarComboBoxEvents_ChangeEventHandler(ComboBox_Change);
}
void ComboBox_Change(Microsoft.Office.Core.CommandBarComboBox Ctrl)

    System.Windows.Forms.MessageBox.Show("Changed");
}

Hi CommandBarComboBox In VISIO,

Welcome to MSDN Forum.

Hi CommandBarComboBox In VISIO,

How is everything going?

I’ve copied the code you provided above, and pasted into my VISIO Add-In project. The change event hasn’t occurred at the first time the Visio launched. It will be nice if you can provide the code of Word edition.

I’m looking forward to your reply.

Best Regards,
Quist
