<br>主题：Clistview视里面计时器为什么只响应2次
<br>内容：用VC生成一SDI，视继承的是Clistview，WM_CREATE建立一个计时器（settimer（1，500，NULL）），WM_TIMER响应，运行后，结果只响应2次，再没反应。<BR>&nbsp;&nbsp; 如果选择视继承Cview，响应就正常。<BR>&nbsp;&nbsp; 哪位高手知道。先谢谢了<BR><BR><BR>下面是设置计时器和响应的函数<BR>int CYWTView::OnCreate(LPCREATESTRUCT lpCreateStruct) <BR>{<BR>&nbsp;&nbsp;&nbsp;&nbsp;if (CListView::OnCreate(lpCreateStruct) == -1)<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return -1;<BR>&nbsp;&nbsp;&nbsp;&nbsp;<BR>SetTimer(1,500,NULL);&nbsp;&nbsp;&nbsp;&nbsp;<BR>&nbsp;&nbsp;&nbsp;&nbsp;<BR>&nbsp;&nbsp;&nbsp;&nbsp;<BR>&nbsp;&nbsp;&nbsp;&nbsp;return 0;<BR>}<BR><BR>void CYWTView::OnTimer(UINT nIDEvent) <BR>{<BR>&nbsp;&nbsp;&nbsp;&nbsp;static int nCounter =0;<BR>&nbsp;&nbsp;&nbsp;&nbsp;CString strText;<BR>&nbsp;&nbsp;&nbsp;&nbsp;strText.Format("Counter = %d",nCounter);<BR>&nbsp;&nbsp;&nbsp;&nbsp;nCounter ++;<BR>&nbsp;&nbsp;&nbsp;&nbsp;CClientDC ClientDC(this);<BR>&nbsp;&nbsp;&nbsp;&nbsp;ClientDC.TextOut(10,10,strText);&nbsp;&nbsp;&nbsp;&nbsp;<BR>&nbsp;&nbsp;&nbsp;&nbsp;CListView::OnTimer(nIDEvent);<BR>}
