在实现多视程序时,我用了一个cview类,一个cformview类,其中cview 是在工程生成时系统帮我生成的,而cformview类是在工程生成后添加的。程序能编译通过,但在运行时会出现ASSERT<em>错误</em>报警。忽略它程序可以继续运行。我在按终止后出现:rnBOOL CView::PreCreateWindow(CREATESTRUCT & cs)rnrn ASSERT(cs.style & WS_CHILD);//这句话有箭头指示rnrn if (cs.lpszClass == NULL)rn rn VERIFY(AfxDeferRegisterClass(AFX_WNDFRAMEORVIEW_REG));rn cs.lpszClass = _afxWndFrameOrView; // COLOR_WINDOW backgroundrn rnrn if (afxData.bWin4 && (cs.style & WS_BORDER))rn rn cs.dwExStyle |= WS_EX_CLIENTEDGE;rn cs.style &= ~WS_BORDER;rn rnrn return TRUE;rnrn我想是cs.style & WS_CHILD为0了,但我不知到该如何设置cs的stytle或其他
