对Exchange中的公用文件夹ItemAdd事件 [英] ItemAdd event on a public folder on Exchange

问题描述

我有附加的事件处理程序公用文件夹的 ItemAdd 事件的一个问题。

问题是一些
成功的来电之后，事件处理程序停止被调用。

代码实在是微不足道。我有一个的ThisAddIn 类，它创建一个对象反过来重视在其构造的 ItemAdd 事件的函数。该功能只弹出一个消息框。

请点我在正确的方向。我只是不明白的地方寻找错误。

感谢你在前进，
阿纳托利

下面是测试代码中，我尝试运行：

 公共部分类的ThisAddIn 
 {
内部静态Outlook.Folder posts_folder = NULL; 
私有静态测试吨; 
 
私人无效ThisAddIn_Startup（对象发件人，发送System.EventArgs）
 {
 
 T =新的测试（）; 
} 
 {
 
类测试
 {
公开测试（）
 {
 System.Windows.Forms.MessageBox。显示（附加...）; 
 ThisAddIn.posts_folder.Items.ItemAdd + =新Microsoft.Office.Interop.Outlook.ItemsEvents_ItemAddEventHandler（Items_ItemAdd）; 
} 
无效Items_ItemAdd（对象的项目）
 {
 System.Windows.Forms.MessageBox.Show（（项目作为Outlook.PostItem）.Subject）; 
} 
} 
  

解决方案

连续谷歌上搜索他的工作的。我发现如何解决这个问题。它似乎我不是谁体验它是唯一一个

我添加了参考我想跟踪的全球范围内的文件夹的项目集合：

 内部静态类STOR 
 {
公共静态Outlook.Items我; 
} 
 
公共部分类的ThisAddIn 
 {
内部静态Outlook.Folder posts_folder = NULL; 
 
私人无效ThisAddIn_Startup（对象发件人，发送System.EventArgs）
 {
 //查找posts_folder代码省略
 
 stor.i = posts_folder.Items; 
 stor.i.ItemAdd + =新Outlook.ItemsEvents_ItemAddEventHandler（Posts_Add）; 
} 
 
静态无效Posts_Add（对象的项目）
 {
 System.Windows.Forms.MessageBox.Show（新项目）; 
} 
 {
  

现在它按预期工作。 Alhough我不明白所有的细节，他们说，这是一个垃圾回收问题。我的事件处理程序最终被扔进垃圾堆。在全球范围内的项目集合的参考防止这种情况的发生。

I have a problem with attaching an event handler to an ItemAdd event of a public folder.

The problem is the event handler stops being called after a few successful calls.

The code is trivial. I have a ThisAddIn class which creates an object which in turn attaches a function to the ItemAdd event in its constructor. The function just pops up a messagebox.

Please point me in the right direction. I simply don't understand where to look for the error.

Thank you in advance, Anatoly

Here is the test code I try to run:

public partial class ThisAddIn
{
    internal static Outlook.Folder posts_folder = null;
    private static test t;

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

        t = new test();
    }
{

class test
{
    public test()
    {
        System.Windows.Forms.MessageBox.Show("Attaching...");
        ThisAddIn.posts_folder.Items.ItemAdd +=new Microsoft.Office.Interop.Outlook.ItemsEvents_ItemAddEventHandler(Items_ItemAdd);
    }
    void Items_ItemAdd(object Item)
    {
        System.Windows.Forms.MessageBox.Show((Item as Outlook.PostItem).Subject);
    }
}

解决方案

Continuous googling did its job. I found how to resolve the issue. It appears I am not the only one who experience it.

I added the reference to Items collection of the folder I want to track to the global scope:

internal static class stor
{
    public static Outlook.Items i;
}

public partial class ThisAddIn
{
    internal static Outlook.Folder posts_folder = null;

    private void ThisAddIn_Startup(object sender, System.EventArgs e)
    {
        // the code for finding a posts_folder is omitted

        stor.i = posts_folder.Items;
        stor.i.ItemAdd += new Outlook.ItemsEvents_ItemAddEventHandler(Posts_Add);
    }

    static void Posts_Add(object Item)
    {
        System.Windows.Forms.MessageBox.Show("New item");
    }
{

Now it works as expected. Alhough I do not understand all the details they say it is a garbage collection issue. My event handler eventually was thrown into the garbage. The reference to the Items collection on the global scope prevents this from happening.
