Context sensitive help is not working

Hi,

I have recently migrated to Windows 7 and found that help file was not supported here.
I have an application where on F1 press, i used to display MyApp.hlp as the help file. After some investigation, i realized and convertedthis MyApp.hlp to MyApp.chm format. I also used ::HtmlHelp() to call this help file. Here is the code snippet that i used to display MyApp.chm:

::HtmlHelp(0, m_pszHelpFilePath, HH_DISPLAY_TOC, NULL) ;

But, here i found that i am not able to display help according to my context.
In many places in my application i had set the Help IDs of different dialogs like:
pDlg->SetHelpID(IDD_BLAH_BLAH_BLAH_1)
pDlg->SetHelpID(IDD_BLAH_BLAH_BLAH_2)
pDlg->SetHelpID(IDD_BLAH_BLAH_BLAH_3)

Now i am not sure how to use these HelpIDs for context sensitive help.
I have tried passing "HH_HELP_CONTEXT", "HH_TP_HELP_CONTEXTMENU" but couldnt seem to get this right.

Can anyone please help me?

Hi brianzion,

Thanks for the reply.
But this doesnt seem to relate to my query. I guess i did not make myself adequately clear in my post.

I am building an MFC application (i started building it in Windows XP). In this application, i had my own help file. I intended that when i press Help, this help file shoud get displayed. It was happening in XP but when i migrated to Win 7 and press F1, i used to get an error message saying that "Failed to launch Help".
Then i learnt that Windows 7 doesnt recognize .hlp as the help file. The other possibilities are .chm, .txt etc. I then converted my help file format from MyApp.hlp to MyApp.chm.

Then i made some changes in my code to launch my help file using HtmlHelp() instead of usual WinHelp(). This also worked for me.
The only problem that i am getting is that say if i am in my first dialog with help ID IDD_BLAH_BLAH_BLAH_1, then on pressing F1, i should directly open the help related to this particular ID (rather that opening the entire help file). In other words, i wanted the help file to be Context sensitive.

Hi Sudipto,

We have the same problem with a .chm file for our application. Normal entry to help file works but context sensitive attempts (F1) fails. Do you ever manage to find a resolution?

Cheers
