VB中Enumchildwindow函数怎么用？

这个函数怎么用，详细点

Answer 1

Private Declare Function EnumChildWindows Lib "user32" Alias "EnumChildWindows" (ByVal hWndParent As Long, ByVal lpEnumFunc As Long, ByVal lParam As Long) As Long
这是一个枚举子窗口的API函数，函数的第一个参数是父窗体的句柄，第二个参数是回调函数的指针，第三个参数是参数。 返回值不用 EnumChildWindows Function The EnumChildWindows function enumerates the child windows that belong to the specified parent window by passing the handle to each child window, in turn, to an application-defined callback function. EnumChildWindows continues until the last child window is enumerated or the callback function returns FALSE.SyntaxBOOL EnumChildWindows(

HWND hWndParent, WNDENUMPROC lpEnumFunc, LPARAM lParam );
