Create help File

Hi
I wanna ask if i can create a help file with c.
To be more specific. I want to add a button that when user will push it it will return a help file with information about the application.
Can someone tell me the steps?? What i need?? Need to write the help file in word?? And in what type?
Any help will be great

I use HTMLHelp from Microsoft to create the help files in CHM format.

Then you can add a button and in the button handler(parent window's WM_COMMAND, the button is the LOWORD of wParam) use ShellExecute with the lpOperation flag set to "open" and the lpFile parameter set to the help file to open the file.

I also use HTMLHelp.
You can use any HTML editor you like and then use HTMLHelp to compile everything into a CHM file.

Ok i will try it and let you know
