Can't open Resource Dialog View
I am doing a project on Visual C++ WinApi. After creating a new file and writing my code, I searched for a variable IDC_Button which is originated from the Resource Dialog. Then I read the Resource.h header file in editor view. Once I have entered the editor mode to view the written code of Resource.h, I couldn't enter back to Dialog view again. When I double clicking the Resources folder, the following box pop up: This file is already open in an editor.
How can I change it back to Dialog view?
I'm using Microsoft Visual Studio 6.0 software.
Thanks for the help.
