The ANNHYPERLINK structure contains information about the changes to be made in automated mode to the specified object.

Member Description
uStructSize Size of the ANNHYPERLINK structure. Use sizeof(ANNHYPERLINK).
uLinkMsg Value indicating a user-defined message that will be sent to the window associated with the annotation object if uType is ANNLINK_USERMSG.
uLinkParam wParam value that is passed to the user-defined message if uType is ANNLINK_USERMSG.
pLinkText Character string containing the program to run when the object is clicked, if uType is ANNLINK_RUN. If uType is ANNLINK_WEBPAGE, it is the URL to be accessed by the default browser. This string should be NULL terminated. This parameter is ignored if uType contains any other value.
uLinkType Constant that specifies the object's hyperlink type. Possible values are:
  Value Meaning
  ANNLINK_NONE [0x0000] Object has no hyperlink.
  ANNLINK_USERMSG [0x0002] The user-defined message will be sent with wParam as the wParam message of this function and lParam containing the handle of the object.
  ANNLINK_RUN [0x0003] The program specified in pLink will be run. Both the program and the command line parameters have to be specified in pLink.
  ANNLINK_WEBPAGE [0x0004] The web page with the URL specified in pLink will be opened in the current browser. Note that not all web browsers accept a page on the command line. Some will simply go to their default home page.
