在 PowerPoint 中添加自定义功能区标签

Question

I try to add a custom ribbon tab in PowerPoint using VSTO in C# (in the ribbon, I want to add a button)

I followed the MSDN tutorial which is intended to Word but must be very similar. I tested the same code for Word or Excel it works ad an "Addin" Tab is added to the ribbon. But with PowerPoint it doesn't.

My code. Here MyRibbon.xml:

<?xml version="1.0" encoding="UTF-8"?>
<customUI xmlns="http://schemas.microsoft.com/office/2009/07/customui" onLoad="Ribbon_Load">
  <ribbon>
    <tabs>
      <tab idMso="TabAddIns">
        <group id="ContentGroup" label="Content">
          <button id="textButton" label="Insert Text"
               screentip="Text" onAction="OnTextButton"
               supertip="Inserts text at the cursor location."/>
          <button id="tableButton" label="Insert Table"
               screentip="Table" onAction="OnTableButton"
               supertip="Inserts a table at the cursor location."/>

        </group>
      </tab>
    </tabs>
  </ribbon>
</customUI>

MyRibbon.cs:

public class MyRibbon : Office.IRibbonExtensibility
    {
        private Office.IRibbonUI ribbon;

        public MyRibbon()
        {
        }

        public string GetCustomUI(string ribbonID)
        {
            return GetResourceText("PowerPointAddIn2.MyRibbon.xml");
        }

        public void Ribbon_Load(Office.IRibbonUI ribbonUI)
        {
            this.ribbon = ribbonUI;
        }

        public void OnTextButton(Office.IRibbonControl control)
        {
            MessageBox.Show("This text was added by the Ribbon.");
        }

ThisAddin.cs :

private void ThisAddIn_Startup(object sender, System.EventArgs e){}
private void ThisAddIn_Shutdown(object sender, System.EventArgs e){}

protected override Microsoft.Office.Core.IRibbonExtensibility CreateRibbonExtensibilityObject()
{
    return new MyRibbon();
}

Every files are under the same project. Do you know what I have forgotten to add the addin Tab appear in PowerPoint ?

Answer 1

your code looks find that your custom ribbon tab should be found within the PowerPoint menuebar under the add-in tab. If you want to create your own tab, change your MyRibbon.xml code to:

<?xml version="1.0" encoding="UTF-8"?>
<customUI xmlns="http://schemas.microsoft.com/office/2009/07/customui" onLoad="Ribbon_Load">
  <ribbon>
    <tabs>
      <tab id="MyRibbonTab" label="MyRibbon">
        <!-- idMso="TabAddIns" -->
        <group id="ContentGroup" label="Content">
          <button id="textButton" label="Insert Text"
               screentip="Text" onAction="OnTextButton"
               supertip="Inserts text at the cursor location."/>
          <button id="tableButton" label="Insert Table"
               screentip="Table" onAction="OnTableButton"
               supertip="Inserts a table at the cursor location."/>

        </group>
      </tab>
    </tabs>
  </ribbon>
</customUI>
