The HELPWININFO structure contains the size and position of either a primary or a secondary Help window. An application can set this information by calling the WinHelp function with the HELP_SETWINPOS value.

typedef struct { // hwi

int wStructSize;

int x;

int y;

int dx;

int dy;

int wMax;

TCHAR rgchMember[2];

} HELPWININFO;

Members
wStructSize

Specifies the structure size, in bytes.

Specifies the x-coordinate of the upper-left corner of the window, in screen coordinates.

Specifies the y-coordinate of the upper-left corner of the window, in screen coordinates.

Specifies the window width, in pixels.

Specifies the window height, in pixels.

wMax

Specifies how to show the window. This member must be one of the following values:

Value	Action
SW_HIDE	Hides the window and passes activation to another window.
SW_MINIMIZE	Minimizes the specified window and activates the top-level window in the Z order.
SW_RESTORE	Same as SW_SHOWNORMAL.
SW_SHOW	Activates a window and displays it in its current size and position.
SW_SHOWMAXIMIZED	Activates the window and displays it as a maximized window.
SW_SHOWMINIMIZED	Activates the window and displays it as an icon.
SW_SHOWMINNOACTIVE	Displays the window as an icon. The window that is currently active remains active.
SW_SHOWNA	Displays the window in its current state. The window that is currently active remains active.
SW_SHOWNOACTIVATE	Displays a window in its most recent size and position. The window that is currently active remains active.
SW_SHOWNORMAL	Activates and displays the window. Whether the window is minimized or maximized, Windows restores it to its original size and position.

rgchMember

Specifies the name of the window.

Remarks
Windows Help divides the display into 1024 units in both the x- and y-directions. To create a secondary window that fills the upper-left quadrant of the display, for example, an application would specify zero for the x and y members and 512 for the dx and dy members.
