Hi Amitjul

Here is probably a solution You've been looking for. You may use:

System.Windows. Forms.SendKeys. SendWait(keys);

method in the follwing way:

		

[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
private static extern bool SetForegroundWindow(IntPtr hWnd);


IntPtr _handle;  //handle to the destination control

public void SendKeys(string keys, int delay) {
			

if(!(SetForegroundWindow(_handle)))
	throw new ExternalException("SetForegroundWindow failed");

System.Windows.Forms.SendKeys.SendWait(keys);
Thread.Sleep(delay);			
}

More info about the keys that can be sent to an active control and about SendKeys.SendWa it(keys) method You will find here:

Hi Guys,
That Guid is the constant which you can't change (i dont know the reason :) ). and AccessibleObjec tFromWindow is working with preety weird way. i tried to decode it but i failed. ne way, i just found a good solution.

IAccessible accObj = (IAccessible)Ac cessibleObjectF romWindow(hwnd, OBJID_WINDOW,
ref uid);

In above code, instead of passing OBJID_WINDOW , try with OBJID_CLIENT

accObj.get_accS tate(0) will return you some integer value like as below:

public const long UNCHECKED = 1048576;
public const long CHECKED = 1048592;
public const long UNCHECKED_FOCUS ED = 1048580; // if control is focused
public const long CHECKED_FOCUSED = 1048596; // if control is focused


so based on that you can easily distiguish that which one is checked (checkbox/radionbutton). Its weird but deadlines are there so.... :)

Hi

When running the code i get 0 when a checkbox is unchecked and 16 when it is checked. The values are not exactly the same as in Your code, however I am able to determine if a checkbox is checked or not.

Thanks a lot!!!

Sorry,

My fault. Amitjul - everything works exactly as in Your code.

PropertyGrid

I was just wondering. Perhaps any of You Guys knows a way to get access to the PropertyGrid component? The problem is that I am unable to find an info about that. E.g:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/platform/commctls/indivcontrol.asp

Under the link above there is an info about many UI components, unfortunately nothing about PropertyGrid :-(

I have found some differences in types on object returend by AccessibleObjec tFromWindow. What I mean is that when working on Win XP, the type of the object is System._ComObje ct , but as I tried on Win 2000 the type was System.Runtime. Remoting.Proxie s._TransparentP roxy . Obviously, I was unable to cast that type to IAccessible, which caused an exception. Does anybody have any idea about those differences?

Thanks

Hello guys,
I'm working in .net C# to get the URL from IE and Firefox. The IE part was over and I'm stuck up at firefox.
I can't drill down to its address bar(combobox) to get its value. So can anybody help me this problem.
I've gone through your above discussion but not getting what I want.
Ive used accExplorer 2.0 to see the hierarchy of the firefox, and I can see the address bar there but problem is how to access it.
