Hello



I am using Windows API. I have 2 edit controls in the dialog box.

I get HWND for each edit control using:

  edit_1_hwnd = GetDlgItem(parent_hwnd,  3);
  edit_1_hwnd = GetDlgItem(parent_hwnd, 4);



The cursor can be in any edit box at any position.



I need to know where the cursor is in edit 1 or in edit 2.

Then I will use

SendMessage (edit_1_hwnd, EM_GETSEL, (UINT)&start, (UINT)&end);

or

SendMessage (edit_2_hwnd, EM_GETSEL, (UINT)&start, (UINT)&end);

to get cursor position.



I tried GetFocus() unsuccessfully



Thank you

Rony

Is it a dialog that you created yourself, or is it a dialog in another
thread/process?

GetFocus() only works if the calling thread is the same thread that is
running the dialog, or if the calling thread has attached itself to the
dialog's thread via AttachThreadInput().

Have you tried GetActiveWindow() yet?

Then GetFocus() should be working.  What is happening exactly when you say
it is not working?  You need to be more specific.  Can you show your actual
code?

Yes, It is a dialog that I create myself
GetActiveWindow()  returns the HWND of the dialog, not of the edit control.
