C＃ActiveX / IE 10 /多个选项卡/获取ActiveX MainWindowHandle

Question

I have an ActiveX project running happily in IE10.

A situation has occured that requires me to obtain the MainWindowHandle of the tab the control is running in.

The following code returns the MainWindowHandle for IE - and not the tab the ActiveX control is running in:

 Process.GetCurrentProcess().MainWindowHandle

If I run this code it returns more than one handle depending on how many tabs are open:

 Process[] IEPROCS = Process.GetProcessesByName("iexplore");
 foreach(Process Proc in IEPROCS) {

     //output code
     Proc.MainWindowHandle.ToString();

 }

So how do I determine the handle of the tab the ActiveX is running in?

For "Legacy" purposes I have to do this in .NET V2 so WindowsInteroptHelper is out of the question.

Answer 1

I would do this:

• Get a Win32 HWND of the control's window: IntPtr hWnd = this.Handle.ToPointer();

• Use GetParent to walk up the parent chain of windows, until I find a window with Win32 class name TabWindowClass ( GetClassName can be used to get the name of the class).

• That would be the HWND of the wanted IE tab.
