CLIENTCREATESTRUCT

3.0

typedef struct tagCLIENTCREATESTRUCT {  /* ccs */
    HANDLE  hWindowMenu;
    UINT    idFirstChild;
} CLIENTCREATESTRUCT;

The CLIENTCREATESTRUCT structure contains information about the menu and first multiple document interface (MDI) child window of an MDI client window. An application passes a long pointer to this structure as the lpParam parameter of the CreateWindow function when creating an MDI client window.

Members

hWindowMenu

Identifies the menu handle of the application's Window menu. An application can retrieve this handle from the menu of the MDI frame window by using the GetSubMenu function.

idFirstChild

Specifies the child window identifier of the first MDI child window created. Windows increments the identifier for each additional MDI child window that the application creates, and reassigns identifiers when the application destroys a window to keep the range of identifiers continuous. These identifiers are used in WM_COMMAND messages to the application's MDI frame window when a child window is selected from the Window menu; they should not conflict with any other command identifiers.
