HELPWININFO  3X_N_9H 

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.

x

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

y

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

dx

Specifies the window width, in pixels.

dy

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.
