windowclosing没有开火 [英] windowclosing not firing
问题描述
嗨
在vb.net中，如果你添加一个webbrowser控件，windowclosing事件就不会发生火灾。我到处寻找一个解决方案而不是我得到更多的人
说我有同样的问题。
我发现这个...有人请转换这个到VB.NET给我们一个
一线希望或者提供一个解决方案。
如果你实现了axWebBrowser，你会发现WindowClosing事件没有'b
$ b fire。这是解决方法，我确认是有效的。
1.在System.Windows.Forms.Form类的正下方添加另一个类
来自SHDocVw .DWebBrowserEvents2。例如：\
公共类IEEvents：SHDocVw.DWebBrowserEvents2
{}
2.保存文件并转到课堂视图（查看|班级视图菜单选项）。转到树视图中的
IEEvents类并展开它。继续扩大孩子
直到你看到''DWebBrowserEvents''。右键单击并选择添加实现
接口''菜单选项。
3.应通过上述步骤生成WindowClosing事件的方法。对方法应用
''DispId''属性，如下所示：
[DispId（0x00000107）]
public void WindowClosing（bool IsChildWindow，ref bool取消）
{
//事件处理程序的消息框工作
MessageBox.Show（" Closing Event"，" IE"，MessageBoxButtons.OK，
MessageBoxIcon.Exclamation）;
}
4.添加以下几行代码到表格的末尾
''InitializeComponent''方法。
UCOMIConnectionPointContainer pConPtCon =
（ UCOMIConnectionPointContainer）this.axWebBrowser1。 GetOcx（）;
UCOMIConnectionPoint pConPt;
Guid guid = typeof（SHDocVw.DWebBrowserEvents2）.GUID;
pConPtCon.FindConnectionPoint（ref guid， out pConPt）;
IEEvents e = new IEEvents（）;
//确保在表单类中声明private int dwCookie但在外面
这种方法
pConPt.Advise（e，out dwCookie）;
5.将以下代码行添加到Forms Close的开头
处理程序方法。
UCOMIConnectionPointContainer pConPtCon =
（UCOMIConnectionPointContainer）this.axWebBrowser1。 GetOcx（）;
UCOMIConnectionPoint pConPt;
Guid guid = typeof（SHDocVw.DWebBrowserEvents2）.GUID;
pConPtCon.FindConnectionPoint（ref guid， out pConPt）;
pConPt.Unadvise（dwCookie）;

Hi
In vb.net if you add a webbrowser control the windowclosing event does not
fire. I have searched everywhere for a solution rather I get more people
saying I have the same problem.
I found this...Could someone please convert this to VB.NET to give us a
glimmer of hope OR provide a solution.
If u implement axWebBrowser, you''ll find the WindowClosing event doesn''t
fire. This is the work around, which I confirm works.
1. Right below the System.Windows.Forms.Form class add another class
whichderives from SHDocVw.DWebBrowserEvents2. For example:\
public class IEEvents: SHDocVw.DWebBrowserEvents2
{}
2. Save the file and go to class view (View | Class View menu option). Go to
IEEvents class in the tree view and expand it. Keep expanding its children
till you see ''DWebBrowserEvents''. Right click and select ''Add | Implement
interfaces'' menu option.
3. A method for WindowClosing event should be generated by above step. Apply
the ''DispId'' attribute to the method as shown below:
[DispId(0x00000107)]
public void WindowClosing(bool IsChildWindow, ref bool Cancel)
{
//message box to the event handler works
MessageBox.Show("Closing Event", "IE", MessageBoxButtons.OK,
MessageBoxIcon.Exclamation);
}
4. Add the following lines of code to the end of the Forms
''InitializeComponent'' method.
UCOMIConnectionPointContainer pConPtCon =
(UCOMIConnectionPointContainer)this.axWebBrowser1. GetOcx();
UCOMIConnectionPoint pConPt;
Guid guid = typeof(SHDocVw.DWebBrowserEvents2).GUID;
pConPtCon.FindConnectionPoint(ref guid, out pConPt);
IEEvents e = new IEEvents();
//make sure you declare private int dwCookie in the form class but outside
this method
pConPt.Advise(e, out dwCookie);
5. Add the following lines of code to the beginning of the Forms Close
handler method.
UCOMIConnectionPointContainer pConPtCon =
(UCOMIConnectionPointContainer)this.axWebBrowser1. GetOcx();
UCOMIConnectionPoint pConPt;
Guid guid = typeof(SHDocVw.DWebBrowserEvents2).GUID;
pConPtCon.FindConnectionPoint(ref guid, out pConPt);
pConPt.Unadvise(dwCookie);

我无法使用VB.Net 2005复制您的错误。我将一个
WebBrowser控件拖到窗体中。然后我添加了一个FormClosing事件。当我关闭表单时，
事件正常触发。也许我对这个问题有误解。
你能发一个简短而完整的程序来解释这个问题吗？
Chris
I cannot duplicate your error using VB.Net 2005. I dragged a
WebBrowser control to the form. I then added a FormClosing event. The
event fired normally when I closed the form. Perhaps I am
misunderstanding the problem.
Can you post a short but complete program that illustrates the problem?
Chris
谢谢Chris
我应该更加详细。
如果您使用java脚本访问html页面以关闭表单，则不会通过webbrowser触发
windowclosing事件。它适用于VB6，但
不是VB.NET，这非常烦人。
我为你设置了一个例子，添加代码并点击关闭按钮。
在vb6
添加webbrowser控件和此代码...
Private Sub Form_Load（）
WebBrowser1.Navigate" www.aztecenergy.co.nz/close.html"
End Sub
Private Sub WebBrowser1_WindowClosing（ByVal IsChildWindow As Boolean，取消
As Boolean）
MsgBox" WindowClosing Fired"
End Sub
现在在VB.NET中添加webbrowser和这段代码
Private Sub Form1_Load（ByVal sender As System.Object，ByVal e As
System.EventArgs）处理MyBase。加载
AxWebBrowser1.Navigate（" www.aztecenergy.co.nz/close.html"）
结束子
Private Sub AxWebBrowser1_WindowClosing（ByVal sender As Object，ByVal e As
AxSHDocVw.DWebBrowserEvents2_WindowClosingEvent ）句柄
AxWebBrowser1.WindowClosing
MessageBox.Show（" WindowClosing Fired"）
End Sub
WindowClosing事件未被触发，因此消息框未显示...
为什么以及如何解决这个问题???

I should of been more detailed.
If you access a html page with java script to close the form the
windowclosing event is not fired through the webbrowser. It works in VB6 but
not VB.NET which is very annoying.
I have set up an example for you, add the code and click on the close button.
In vb6
Add the webbrowser control and this code...
Private Sub Form_Load()
WebBrowser1.Navigate "www.aztecenergy.co.nz/close.html"
End Sub
Private Sub WebBrowser1_WindowClosing(ByVal IsChildWindow As Boolean, Cancel
As Boolean)
MsgBox "WindowClosing Fired"
End Sub
Now in VB.NET add the webbrowser and this code
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
AxWebBrowser1.Navigate("www.aztecenergy.co.nz/close.html")
End Sub
Private Sub AxWebBrowser1_WindowClosing(ByVal sender As Object, ByVal e As
AxSHDocVw.DWebBrowserEvents2_WindowClosingEvent) Handles
AxWebBrowser1.WindowClosing
MessageBox.Show("WindowClosing Fired")
End Sub
The WindowClosing event is not fired and thus the messagebox is not shown...
Why and how do I fix this???

Chad，
我认为你的样品有点混合但是。
2.0 webbrowser中的事件非常非常不如AxWebbrowser中的
。正如Herfried所展示的那样，可以为那些创建
的变通办法。我不知道这个的解决方法。
也许如果没有退回的文件。

Chad,
I assume that your samples are a little bit mixed up, however.
The events in the 2.0 webbrowser are very very very much inferior to the
ones in the AxWebbrowser. As Herfried ones showed is it possible to create
workarounds for those. I don''t know a workaround for this one.
Maybe if there are no returned documents.
