I´ve made an Dialog based app. And now I´ve also made a myhlp.hlp file. I have a button on my MFC app and now I want´to know the code for launching my hlp file when I click the button. I would really like the code for this since I´m new at MFC.

Simply handle the button press like any other button and call AfxGetApp()->WinHelp(<helpid>) where <helpid> is the identifier of the topic in the help file.

I´m sorry but it doesn´t work, I´ve tried many different ways. I need to call the right help file also I tried to use the name but I don´t understand what you mean with HelpId, I´ve tried using the Id that I use when I call the topics in the Help file but that doesn´t work it comes up as undeclared identifier.
I would like some more help please....

this API can do that for you :

::WinHelp(hWnd,"c:\\help.hlp",HELP_CONTENTS ,0);

or you can modify the CWinApp:: m_pszHelpFilePath
and then call CWinApp::OnHelp();

Thank you very much, it should be HELP_FINDER instead of HELP_CONTENTS.
