webBrowser中的问题，BHO、DispId的问题，做过的进来
这2段是从某个国外牛人写的代码中抄袭出来的，可以正常运行
// COM Event Handler for HTML Element Events
[DispId(0)]
public void DefaultMethod()
{
// obtain the event object and ensure a context menu has been applied to the document
HtmlEventObject eventObject = document.parentWindow.@event;
string eventType = eventObject.type;
// Call the custom Web Browser HTML event
ContextMenuShow(this, eventObject);
} //DefaultMethod
private void BrowserDocumentComplete(object sender, AxSHDocVw.DWebBrowserEvents2_DocumentCompleteEvent e)
{
// get access to the HTMLDocument
document = (HtmlDocument)this.axWebBrowser1.Document;
// add style sheet link
string href = Path.GetTempPath() + "/StyleMain.css ";
LinkStyleSheet(href);
body = (HtmlBody)document.body;
// COM Interop Start
// once browsing has completed there is the need to setup some options
// need to ensure URLs are not modified when html is pasted
IOleCommandTarget target = null;
int hResult = HRESULT.S_OK;
// try to obtain the command target for the web browser document
try
{
// cast the document to a command target
target = (IOleCommandTarget)document;
// set the appropriate no url fixups on paste
hResult = target.Exec(ref CommandGroup.CGID_MSHTML, (int)CommandId.IDM_NOFIXUPURLSONPASTE, (int)CommandOption.OLECMDEXECOPT_DONTPROMPTUSER, ref EMPTY_PARAMETER, ref EMPTY_PARAMETER);
}
// catch any exception and map back to the HRESULT
catch (Exception ex)
{
hResult = Marshal.GetHRForException(ex);
}
// test the HRESULT for a valid operation
if (hResult == HRESULT.S_OK)
{
// urls will not automatically be rebased
rebaseUrlsNeeded = false;
}
else
{
//throw new HtmlEditorException(string.Format( "Error executing NOFIXUPURLSONPASTE: Result {0} ", hResult));
rebaseUrlsNeeded = true;
}
// COM Interop End
// at this point the document and body has been loaded
// so define the event handler as the same class
//document.oncontextmenu = this;
((mshtml.DispHTMLDocument)document).oncontextmenu = this;
// 这句话是我加的，他只能相应DisoId(0)的方法
((mshtml.DispHTMLDocument)document).ondblclick = this;
// complete
isloading = false;
} //BrowserDocumentComplete
下面是我加的方法：
[DispId(3)]
public void WebDoubleClick()
{
HtmlEventObject eventObject = document.parentWindow.@event;
string eventType = eventObject.type;
MessageBox.Show( "Double Click : " + eventType);
}
现象是只相应DispId(0)的方法，而我想双击触发DispId(3)的方法应该怎么做？
