Advice for how to do what? If you did it for one textbox there should be no trouble at all for you to do the same thing for another textbox.

I still don't know how to chose in what texbox to drop ,when I'm in "DropFiles()" function:

SetDlgItemText(IDC_EDIT_OPEN,szDroppedFile);
or
SetDlgItemText(IDC_EDIT_SAVE,szDroppedFile);

Well since we cannot see your code or your monitor or read your mind, how would you expect us to know what your "DropFile" function looks like or does?

You can either:

1. Handle the HDROP pointer to a DROPFILES structure that comes as a parameter in your OnDropFile() function. See http://msdn.microsoft.com/en-us/library/windows/desktop/bb773269%28v=vs.85%29.aspx[^]

You can then make a hit test between your textboxes coordinates and the pt POINT of the DROPFILEs structure to find in which it has landed.

2. Or, instead of handling the drop event in the main window, as I suppose you did, you might handle it in the textbox classes.

On a side note, I am surprised you are mixing plain Win32 (SetDlgItemText) and MFC code (OnDropFile())...
