SUMMARY

The Remarks documentation for the function WinHelp() regarding the fourth parameter (DWORD dWord // other info) incorrectly states: 

   HELP_SETPOPUP_POS  Sets the position of the subsequent pop-up window.
     Address of a POINTS structure. The pop-up window is positioned as if
     the mouse cursor were at the specified point when the pop-up window is
     invoked.
The function actually expects a POINTS structure, rather than an address to the structure. When you pass an address, a misplaced pop-up menu appears.

You can pass the information to WinHelp() by using the MAKELONG macro to set the fourth parameter as follows: 

   dWord = MAKELONG(left,top)
where the two parameters represent the desired positions of the pop-up menu.

Additional query words: HELP_SETPOPUP_POS WinHelp POINTS
