How to use ShellWindows class in IE's Protected Mode?

Question

            shellWindows = new SHDocVw.ShellWindowsClass();
            int handle = 0;
            handle = GetForegroundWindow();


            foreach (SHDocVw.WebBrowser ie in shellWindows)
            {

                //find the instance    
                if (ie.HWND == handle)
                {

                    doc = ie.Document as mshtml.HTMLDocument;
                    if (doc.hasFocus())
                    {
                       
                        break;
                    }
                }
            }

 

 

 

 

The code above (for getting current active tab/windows) works fine with IE's protected mode is OFF.

Please help me if I can bypass the Protected Mode or use an alternative class to deal with it.

Thanks in advandce.

Hi Mai,

 

Based on this security features

 

User Interface Privilege Isolation (UIPI) prevents processes from sending selected window messages and other USER APIs to processes running with higher integrity.

 

In this Understanding and Working in Protected Mode Internet Explorer document, we can see that in the project mode, we cannot access the handle of other application in other processes. Therefore, I think you cannot bypass the protected mode.

 

I hope these information can help you to solve this problem.

 

Best regards,

Jesse
