VC编程经验汇总2009-10-081. 显示和隐藏标题栏

方法一：使用API实现

//隐藏TitleBar

LONG lStyle = ::GetWindowLong（this->m_hWnd, GWL_STYLE）;

::SetWindowLong（this->m_hWnd, GWL_STYLE, lStyle & ~WS_CAPTION）;

::SetWindowPos（this->m_hWnd, NULL, 0, 0, 0, 0,

SWP_NOSIZE | SWP_NOMOVE | SWP_NOZORDER | SWP_NOACTIVATE | SWP_FRAMECHANGED）;

// 显示TitleBar

::SetWindowLong（this->m_hWnd, GWL_STYLE, lStyle | WS_CAPTION）;

::SetWindowPos（this->m_hWnd, NULL, 0, 0, 0, 0,？？SWP_NOSIZE | SWP_NOMOVE | SWP_NOZORDER | SWP_NOACTIVATE | SWP_FRAMECHANGED）;

方法二：使用CWnd成员函数ModifyStyle实现

// 隐藏TitleBar

ModifyStyle（WS_CAPTION, 0, SWP_FRAMECHANGED）;

// 显示TitleBar

ModifyStyle（0, WS_CAPTION, SWP_FRAMECHANGED）;

2 . 怎么用SendMessage（）来发送消息来清空它的内容？？

HWND hEditWnd=GetDlgItem（IDC_EDIT1）->GetSafeHwnd（）;

::SendMessage（hEditWnd,WM_SETTEXT,（WPARAM）0,（LPARAM）""）;

3. 弹出文件的属性窗口

SHELLEXECUTEINFO ShExecInfo ={0};

ShExecInfo.cbSize = sizeof（SHELLEXECUTEINFO）;

ShExecInfo.fMask = SEE_MASK_INVOKEIDLIST ;

ShExecInfo.hwnd = NULL;

ShExecInfo.lpVerb = "properties";

ShExecInfo.lpFile = "c:"; //也可以是文件

ShExecInfo.lpParameters = "";

ShExecInfo.lpDirectory = NULL;

ShExecInfo.nShow = SW_SHOW;

ShExecInfo.hInstApp = NULL;

ShellExecuteEx（&ShExecInfo）;
