DOC: WinHelp Function Expects a POINTS Structure (167341)
The information in this article applies to:
- Microsoft Platform Software Development Kit (SDK) 1.0
This article was previously published under Q167341 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.
