Question

我正在使用VS 2010开发Excel 2007 COM加载项。因为它是VS 2010 Office Project，所以它面向.NET 4.0 Client Framework。我添加了一个名为MyRibbon的新Ribbon（XML）项，因此默认文件名为ThisAddIn.cs，MyRibbon.cs和MyRibbon.xml。

一切都很好。它以.vsto扩展名发布。当我安装加载项（通过提供的Setup.exe）时，它将安装Excel，并在COM加载项列表中进行检查。它也被指定在启动时加载。但是，首先打开Excel或打开Excel文件不会将选项卡添加到功能区。

我可以告诉Add-In加载，因为它在第一个工作表的第一个单元格中加载了“COM加载项”。似乎没有调用CreateRibbonExtensibilityObject（）。

有没有人有任何想法，或者可以告诉我如何显示可能被隐藏的任何错误消息？

详情如下。

我添加了CreateRibbonExtensibilityObject（）的覆盖：

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

MyRibbon.xml看起来像这样，标签内的一组中有三个按钮：

<?xml version="1.0" encoding="UTF-8"?>
<customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui" onLoad="Ribbon_Load">
  <ribbon>
    <tabs>
      <tab id="TabAdvComTracking" idMso="TabAdvComTrackingMso" label="Adv.com Tracking">
        <group id="groupPrepare" label="Prepare">
          <button id="GenerateNewWorkbook" idMso="GenerateNewWorkbookMso" enabled="1" size="large" onAction="GenNewWorkbook" label="Make"  />
          <separator visible="1"/>
          <button id="ClearData" idMso="ClearDataMso" enabled="1" size="large" onAction="ClearData" label="Clear" />
        </group>
        <group id="GroupDoIt" idMso="GroupDoItMso" label="Just Do It">
          <button id="CaptureIds" idMso="CaptureIdsMso" enabled="1" size="large" onAction="CaptureData" label="Eat" />
        </group>
      </tab>
    </tabs>
  </ribbon>
</customUI>

MyRibbon.cs看起来像这样：

Answer 1

我遇到了同样的问题。我有一个不正确的XML文件路径，它返回空：

 public string GetCustomUI(string ribbonID)
 {
    return GetResourceText("CheckThisIsTheCorrectNameSpace.Ribbon.xml");
 }

将命名空间硬编码为字符串并不是一个好主意，主要是因为它们不是可重构的，以及我们的Stackoverflow在其他人的评论中提到的有用的原因。

Answer 2

您应该删除CreateRibbonExtensibilityObject的覆盖。默认情况下，这是由ThisAddIn的基类实现的，并调用CreateRibbonObjects。您可以覆盖CreateRibbonObjects（这应该返回所有Ribbon对象的数组），或者只是让CreateRibbonObjects的默认实现做它的事情（也就是说，每次你的addin启动时反映整个程序集）。 / p>

尝试更改默认TabAddIns时遇到同样的问题。我看到的是idMso用于办公室栏标签，id用于新标签。以下适用于我。

<tab id="TabAdvComTracking" tag="TabAdvComTracking" label="Adv.com Tracking" visible="true" insertAfterMso="TabAddIns">

VSTO Excel Com添加功能区未加载
