An application sends the WM_MDICASCADE message to a multiple document interface (MDI) client window to arrange all its child windows in a cascade format.
WM_MDICASCADE
wParam = (WPARAM) (UINT) fuCascade; // cascade flag
lParam = 0; // not used; must be zero
Parameters
fuCascade
Value of wParam. Specifies a cascade flag. The only flag currently available, MDITILE_SKIPDISABLED, prevents disabled MDI child windows from being cascaded.
Return Values
If the message succeeds, the return value is TRUE.
If the message fails, the return value is FALSE.
