HH_AKLINK Structure

Microsoft Corporation

Updated June 10, 1999

Use this structure to specify one or more ALink names or KLink keywords that you want to search for.

If the lookup yields no matching topics, HtmlHelp() checks the values of the following HH_AKLINK members to determine what alternative action to take:

fIndexOnFail. If fIndexOnFail is TRUE, the Index tab is selected in the help window specified in pszWindow, and the keyword specified in pszKeyword is selected in the entry field.
pszURL. If fIndexOnFail is FALSE, the topic file specified in pszURL appears in the help window specified in pszWindow.
pszMsgText and pszMsgTitle. If fIndexOnFail is FALSE and pszURL is NULL, a message box appears using the text and caption specified in pszMsgText and pszMsgTitle.

HH_AKLINK structure syntax

typedef struct tagHH_AKLINK

     int      cbStruct;      


     BOOL     fReserved;


     LPCTSTR  pszKeywords;      


     LPCTSTR  pszUrl;       


     LPCTSTR  pszMsgText;

} HH_AKLINK;

Member	Description
cbStruct	Specifies the size of the structure. This value must always be filled in before passing the structure to the HTML Help API.
fReserved	This parameter must be set to FALSE.
pszKeywords	Specifies one or more ALink names or KLink keywords to look up. Multiple entries are delimited by a semicolon.
pszUrl	Specifies the topic file to navigate to if the lookup fails. pszURL refers to a valid topic within the specified compiled help (.chm) file and does not support Internet protocols that point to an HTML file.
pszMsgText	Specifies the text to display in a message box if the lookup fails and fIndexOnFail is FALSE and pszURL is NULL.
pszMsgTitle	Specifies the caption of the message box in which the pszMsgText parameter appears.
pszWindow	Specifies the name of the window type in which to display one of the following: The selected topic, if the lookup yields one or more matching topics. The topic specified in pszURL, if the lookup fails and a topic is specified in pszURL. The Index tab, if the lookup fails and fIndexOnFail is specified as TRUE.
fIndexOnFail	Specifies whether to display the keyword in the Index tab of the HTML Help Viewer if the lookup fails. The value of pszWindow specifies the Help Viewer.

Comments

ALink name and KLink keyword lookups are case sensitive, and multiple keywords are delimited by a semicolon.
If the lookup yields one or more matching topics, the topic titles appear in the Topics Found dialog box.
