Don't show a message box when copy a file name.

I want #include a header file name in a .cpp file, so i do as follow:
1. I select a .h file in the left project treeview.
2. I use F2 shortcut to active the .h file to let it be in edit status.
3. I copy the .h file name.
4. I click the mouse to the .cpp file and paste the .h file name.
when i do this, there is a messbox show:

---------------------------
Cannot Rename File
---------------------------
The file XXXX.h could not be renamed XXXX.h.
---------------------------
OK
---------------------------

I didn't rename the file name, i just want copy the file name, so please don't show me the messagebox when the filename didn't change.

Thanks!
