settimer在win32 application中使用的问题

[eidiot]

如下这个程序并没有弹出我所期望的test消息框，
据说是因为settimer只能在有窗口的程序中使用，不知
这种说法对不对？还是我这个小程序本身有问题？// testoftimer2.cpp : Defines the entry point for the application.
//

#include "stdafx.h"
# include "windows.h"
# include "winuser.h"
# include "winbase.h"
VOID CALLBACK test(HWND hwnd, UINT uMsg, UINT idEvent, DWORD dwTime)

{

MessageBox(NULL,"test","test",MB_OK);

}
int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{
// TODO: Place code here.
MessageBox(NULL,"main","main",MB_OK);
UINT ret;
ret=::SetTimer(
NULL, // handle of window for timer messages
0, // timer identifier
1000, // time-out value
test // address of timer procedure
);

Sleep(100);
return 0;

}

必须在有消息循环的线程中，可以没有窗口。

我win32 application中如此的使用，首先：
m_TimerID = SetTimer(hWnd,1000,1000,NULL);

LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
{
.......
case WM_TIMER:
if(1000==m_TimerID)
{
m_nStep++;
}
if(m_nStep==m_nWorkTime)
{
MessageBox(hWnd,"timer",NULL,MB_OK);
m_nStep=0;
}
break ;
...........
}
