注册InternetExplorer活动 [英] Register to InternetExplorer events

问题描述

大家好，

我们需要在Outlook中单击按钮打开InternetExplorer实例。另外，如果有一个这样的InternetExplorer实例（从Outlook打开）已经打开，用户将无法从Outlook打开
InternetExplorer的新实例。以下是我们为实现此目的所采取的步骤：

We have a requirement in where we need to open a InternetExplorer instance on click of button in Outlook. Also if one such instance of InternetExplorer (opened from Outlook) is already opened, user will not be allowed to open a new instance of InternetExplorer from Outlook. Below are the steps that we did to achieve this:

1. 在插件启动时将布尔变量（isIElaunched）设置为false。
2. 单击outlook按钮时，启动InternetExplorer实例并将布尔变量（isIElaunched）设置为true。
3. 注册刚刚启动的InternetExplorer实例的退出事件。
4. On退出浏览器，再次将布尔变量设置为false。

问题： 从插件测试时，已注册的浏览器事件正在间歇性地工作。但是当从控制台应用程序使用相同的代码片段时，该事件工作正常。以下是我们使用的
代码段。有人可以告诉我出错的地方。

Issue: The registered browser event is working intermittently when testing from plugin. But when using the same code snippet from a console application, the event is working fine. Below is the code snippet what we have used. Can someone advice where I am going wrong.

此外，当使用InternetExplorer.Navigate函数时，它会立即调用Quit事件。

Additionally, when using InternetExplorer.Navigate function, it is immediately invoking the Quit event.

public void onClickOutlookBtn(Office.IRibbonControl control)
{
    string postParams = "param1=param1Val&param2=param2Val";
    string PostHeaders = "Content-Type: application/x-www-form-urlencoded";
    string url = "a sample web url";
    InternetExplorer ieObject = new InternetExplorer();
    ((DWebBrowserEvents_Event)ieObject).Quit += new DWebBrowserEvents_QuitEventHandler(Quit);
     ieObject.Visible = true;
     isIElaunched = true;
     ieObject.Navigate(url, null, null, post, PostHeaders);
}

public void Quit（ref bool Cancel）
{
    System.Windows.Forms.MessageBox.Show（" IE CLOSED"）;
    isIELaunched = false;

public void Quit(ref bool Cancel)
{
    System.Windows.Forms.MessageBox.Show("IE CLOSED");
    isIELaunched = false;

}

根据您的描述，我已经做了一个样本试图重现这个问题，但我发现有一些语法错误，我已修复然后运行此示例，遗憾的是，我无法重现它。



添加名为"RibbonIEXml"的功能区（XML）

>>> The registered browser event is working intermittently when testing from plugin. But when using the same code snippet from a console application, the event is working fine. Below is the code 

snippet what we have used. Can someone advice where I am going wrong.<<<

According to your description, I have made a sample to try to reproduce this issue, but I find there are some syntax errorr, I have fixed then run this sample, unfortunately, I can't reproduce it.

Add Ribbon(XML) named "RibbonIEXml"

<?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="MyGroup"
               label="My Group">
          <button id="btnIE" label="Internet Explorer" onAction="onClickOutlookBtn"/>
        </group>
      </tab>
    </tabs>
  </ribbon>
</customUI>

回调代码：

Callback code:

bool isIELaunched = false;
public void onClickOutlookBtn(Office.IRibbonControl control)
{
    string postParams = "param1=param1Val&param2=param2Val";
    string postHeaders = "Content-Type: application/x-www-form-urlencoded";
    string url = "https://www.google.com.sg/?gfe_rd=cr&ei=11SEV9r4K-HN8ge55IywCA";
    InternetExplorer ieObject = new InternetExplorer();
    ((DWebBrowserEvents_Event)ieObject).Quit += new DWebBrowserEvents_QuitEventHandler(Quit);
    ieObject.Visible = true;
    isIELaunched = true;
    ieObject.Navigate(url, null, null, postParams, postHeaders);
}
public void Quit(ref bool Cancel)
{
    System.Windows.Forms.MessageBox.Show("IE CLOSED");
    isIELaunched = false;
}
