Invoke chm help in access 2007

I have created chm help for an access 2007 application and entered the path and help context ID's to the mdb but in Access 2007 the What's This button seems to have been discontinued.

How do I invoke the chm help file in my access program.

Ive used .hlp (winhelp) files before not chm and all I had to do was hit F1 on the appropriate place (where context id specified)
Dunno if that is still the case with CHMs?

Rockiroads,

Apparently it is not with chm files as I have tried that.  My chm help file is in C:\Program Files\MyAppHelp\
and I have opened the file using the path from the Help File property in the Access form so I know the path is good.  

In Access 2003 there used to be a form property called "What's This" that would open the chm help file when the What's This question mark icon was clicked and the field that help was wanted for was clicked.  Now the What's This feature seems to be gone from Access 2007 so I need to know how to call my chm help.

Thanks,
merdeka

rockiroads,

I don't see it there.  Maybe its me but my experience with Microsoft help for Access is frustration 95% of the time.

rockiroads,

I checked the link you provided above but the answer doesn't seem to be there either.  Maybe Microsoft has found that (their) help files are useless so we don't need them anymore.

rockiroads,

The F1 key won't open MS Access help or my custom help file in design view (i.e. my program form active) - is this normal?.  When I click F1 the mouse pointer momentarily changes to an hourglass then back to a pointer.  The f1 key works in design view and in the code window.

Thanks,

My understanding was that if you specify the help file in a form, F1 would be looking for that using the context id's to find the right page but only during runtime.

when I did winhelp pages longtime back (now redundant), this is what I did, set the help file then that help file had id's set. The form would then use one of them id's.
Ive no idea about chm's though. There might be a similar thing

rockiroads,

I have added help to a number of Access 2003 programs and it was nothing like what is described in the link above.  

In Access 2003 I just added the chm help file contextID in the Other > Help contedt ID field of the form property sheet or the object property sheet and added the path to the chm help file in Help file property of the form and it worked fine.  The difference I can see between Access 2007 and Access 2003 is that Access 2003 had a propery called 'What's this?' which put a question mark in the title bar of the form which you could click and then click on the object in question and the chm help file would open.

rockiroads,

I tried the code from the link above and the macro from the link above (RoryJakes code and ptPaton modification) but it still doesn't work (please see attached code snippet).  I don't have a contextID of 1001 but I tried it with contextID 1001 and contextID 100 in the code, I do have contextID 100 in my CHM file, but nothing happens when I click the F1 key.

BostonFrog (same article) mentions something about ALIAS and MAP which I don't understand.

Thanks,
merdeka
