The EnumThreadWindows function enumerates all nonchild windows associated with a thread by passing the handle of each window, in turn, to an application-defined callback function. EnumThreadWindows continues until the last window is enumerated or the callback function returns FALSE. To enumerate child windows of a particular window, use the EnumChildWindows function. This function supersedes the EnumTaskWindows function.
BOOL EnumThreadWindows(
DWORD dwThreadId, // thread identifier
WNDENUMPROC lpfn, // pointer to callback function
LPARAM lParam // application-defined value
);
Parameters
dwThreadId
Identifies the thread whose windows are to be enumerated.
lpfn
Points to an application-defined callback function. For more information about the callback function, see the EnumThreadWndProc callback function.
lParam
Specifies a 32-bit, application-defined value to be passed to the callback function.
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero.

BOOL EnumThreadWindows(
DWORD dwThreadId, // thread identifier
WNDENUMPROC lpfn, // pointer to callback function
LPARAM lParam // application-defined value
);
Parameters
dwThreadId
Identifies the thread whose windows are to be enumerated.
lpfn
Points to an application-defined callback function. For more information about the callback function, see the EnumThreadWndProc callback function.
lParam
Specifies a 32-bit, application-defined value to be passed to the callback function.
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero.

The EnumChildWindows function enumerates the child windows that belong to the specified parent window by passing the handle of 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.
BOOL EnumChildWindows(
HWND hWndParent, // handle to parent window
WNDENUMPROC lpEnumFunc, // pointer to callback function
LPARAM lParam // application-defined value
);
Parameters
hWndParent
Identifies the parent window whose child windows are to be enumerated.
lpEnumFunc
Points to an application-defined callback function. For more information about the callback function, see the EnumChildProc callback function.
lParam
Specifies a 32-bit, application-defined value to be passed to the callback function.
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero.
Remarks
The EnumChildWindows function does not enumerate top-level windows owned by the specified window, nor does it enumerate any other owned windows.
If a child window has created child windows of its own, this function enumerates those windows as well.
A child window that is moved or repositioned in the Z order during the enumeration process will be properly enumerated. The function does not enumerate a child window that is destroyed before being enumerated or that is created during the enumeration process.
This function is more reliable than calling the GetWindow function in a loop. An application that calls GetWindow to perform this task risks being caught in an infinite loop or referencing a handle to a window that has been destroyed.

EnumChildWindows函数怎么用啊？能给段代码吗？

先 找到TPUtilWindow的句并
MyHandle:=Findwindow(nil,TPutilWindow)
然后用EnumChildWindows
MyHandle:=Findwindow(nil,TPutilWindow)
然后用EnumChildWindows
