HH_HELP_CONTEXT and MAP Section

[Chip Pearson]

I'm using the HTMLHELP API function to work with CHM Help files in my
application. I've subclassed the form to detect the WM_HELP message. When my
form receives this message (user hits F1), I execute the code:

Result = HtmlHelp (0&, App.HelpFile, HH_HELP_CONTEXT,
Me.ActiveControl.HelpContextID)

where the HelpContextID for the control is 1000.

When the code runs, I get an error message from "HTML Help Author Message"
that states "HH_HELP_CONTEXT called without a [MAP] section."

My Help project does indeed have a [MAP] section.

In the Help project, I have a text file named PopupTopics.txt which contains
text like:

.topic IDH_RegistryValueName
This is some help text to popup about the Registry.

I have a file named Alias.h which contains text like

IDH_RegistryValueName=RegistryName.htm
IDH_RegistryValueValue=RegistryValue.htm
IDH_IgnoreMissongAttacmentFiles=IgnoreMissongAttacmentFiles.htm
IDH_CDOServerName=CDOServerName.htm

I have a file named ctxhelp.h with contains text like

#define IDH_RegistryValueName 1000
#define IDH_RegistryValueValue 1010
#define IDH_IgnoreMissongAttacmentFiles 1030
#define IDH_CDOServerName 1040

In the MAP section of my HTML Help Project, I have
#include Alias.h
#include ctxhelp.h
listed in the Map tab.

In the Text Pop-ups tab, I have
PopupTopics.txt

In the Alias tab, I have
1000=RegistryName.htm
1010=RegistryValue.htm
Error_1=Error_1.htm

What am I missing, and why do I get the error message?

Thanks for any help you can provide.

I think you just need to reorganise the ALIAS and MAP sections of your
project file, like this:

[ALIAS]
#include Alias.h

[MAP]
#include ctxhelp.h

That should fix the problem (because the correct alias strings are now in
the ALIAS section rather than the MAP section).
