HH_INITIALIZE Command

---

Microsoft Corporation

Updated June 10, 1999

This command initializes the help system for use and must be the first HTML Help command called. It returns a cookie which must be used in the HH_UNINITIALIZE call.

HH_INITIALIZE configures HTML Help to run on the same thread as the calling application instead of a secondary thread by setting the global property HH_GPROPID_SINGLETHREAD to VARIANT_TRUE. Running HTML Help on the same thread as the calling application requires the calling application to send messages to HTML Help by calling the HH_PRETRANSLATEMESSAGE command.

pszFile	dwData
Must be NULL.	Specifies a pointer to a DWORD. This call returns a cookie that you must pass as the value of dwData when you call HH_UNINITIALIZE.

Example

DWORD dwCookie = NULL;




HtmlHelp(


         NULL, 


         NULL, 


         HH_INITIALIZE, 


         (DWORD)&dwCookie) ; // Cookie returned by Hhctrl.ocx.

Comments

• Call HH_INITIALIZE before calling any other command and call HH_UNINITIALIZE only when your application ends. You should call these commands once during the life of your application.
