VC编程经验汇总

1. 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);
