C# CommandBarButton problem

C# CommandBarButton problem

• Fantasio

  I have solved my problem. It was very important to specify the correct "newButton.Style". See below. The ComandBarButton contains 49 private, 20 public and reserved, a total of 69 members! It was difficult to figure out "what" to pass to some of these members as they are sparsely documented. I literally stumbled into the solution by looking at many different C# code examples :)

  // Begin Sample C#, Add a CommandBarButton to all instances of Inspectors.

  using System;

  using System.Windows.Forms;

  using Microsoft.VisualStudio.Tools.Applications.Runtime;

  using Outlook = Microsoft.Office.Interop.Outlook;

  using Office = Microsoft.Office.Core;

  namespace OutlookAddin

  {

  public partial class ThisApplication

  {

  private Office.CommandBar newBar;

  private Office.CommandBarButton newButton;

  private Outlook.Inspectors inspectors;

  private void ThisApplication_Startup(object sender, System.EventArgs e)

  {

  inspectors = this.Inspectors;

  inspectors.NewInspector += new Microsoft.Office.Interop.Outlook.InspectorsEvents_NewInspectorEventHandler(inspectors_NewInspector);

  }

  private void ThisApplication_Shutdown(object sender, System.EventArgs e)

  {

  }

  private void inspectors_NewInspector(Outlook.Inspector inspector)

  {

  // Check for previous instance of CommandBar, don't add it if it exists

  for (int i = 1; i <= inspector.CommandBars.Count; i++)

  if (inspector.CommandBars.Name == "ExportControlBar") return;

  // Add the CommandBar

  newBar = inspector.CommandBars.Add("ExportControlBar", Office.MsoBarPosition.msoBarTop, false, true);

  // Add a button

  newButton = (Office.CommandBarButton)newBar.Controls.Add(

  Office.MsoControlType.msoControlButton, 1, missing, missing, true);

  newButton.Caption = "Export data";

  newButton.Style = Microsoft.Office.Core.MsoButtonStyle.msoButtonCaption;

  newButton.Click += new Microsoft.Office.Core._CommandBarButtonEvents_ClickEventHandler(newButton_Click);

  newBar.Visible = true;

  }

  // Display a Message Box in response to button click.

  private void newButton_Click(Office.CommandBarButton Ctrl, ref bool CancelDefault)

  {

  MessageBox.Show("Exporting Data");

  }

  this.Shutdown += new System.EventHandler(ThisApplication_Shutdown);

  }

  }

  // End Sample C#, Add a CommandBarButton to all instances of Inspectors.
