爱华网函数代码： BOOLModifyControlStyle(CWnd* pWnd,LPCTSTR lpszClassName,DWORDdwRemove,DWORD dwAdd,DWORD dwRemoveEx,DWORD dwAddEx){CWnd* pParentWnd = pWnd->GetParent();
CFont* pFont = pWnd->GetFont();
CString strText;pWnd->GetWindowText(strText);
CRect rcWindow;pWnd->GetWindowRect(&rcWindow);pParentWnd->ScreenToClient(rcWindow);
DWORD dwNewStyle = (pWnd->GetStyle()& ~dwRemove) | dwAdd;DWORD dwNewStyleEx = (pWnd->GetExStyle()& ~dwRemoveEx) | dwAddEx;
UINT nID = pWnd->GetDlgCtrlID();
pWnd->ShowWindow(SW_HIDE);pWnd->DestroyWindow();
BOOL bResult =pWnd->CreateEx(dwNewStyleEx,lpszClassName,strText,dwNewStyle,rcWindow,pParentWnd,nID);
pWnd->SetFont(pFont);
return bResult;}
调用代码： 1、增加密码属性 CWnd* pWnd =GetDlgItem(IDC_EDIT_SPECULATION);ModifyControlStyle(pWnd,"Edit",0,ES_PASSWORD,0,0); 2、移除密码属性 CWnd* pWnd =GetDlgItem(IDC_EDIT_SPECULATION);ModifyControlStyle(pWnd,"Edit",ES_PASSWORD,0,0,0);
