My teacher gave me a project that i have to write a program like Notepad , but he also request when i use File->Open , there is a preview in that Open Dialog to view the Text file that i selected . I know that i must Customize the Common Dialog but the truth is i don't know where to start .
I've told that i have to define again the template in Fileopen.dlg . But my questions are :
1/when i define it again , what about all the function that it provide ? Example like GetOpenFileName , how can i reuse it ?
2/How can i add the Preview section in that Dialog box that can view text file ?
I just need the idea to do it. Thanks for reading .
