一些常用的VC编程函数

MFC中从剪切板取出数据的函数

{

    // TODO: Add your control notification handler code here

    if(OpenClipboard())

    {

        if(IsClipboardFormatAvailable(CF_TEXT))

        {

            HANDLE hClip;

            char *pBuf;

            hClip=GetClipboardData(CF_TEXT);

            pBuf=(char *)GlobalLock(hClip);

            GlobalUnlock(hClip);

        }

        

CloseClipboard();

    }

}

 

MFC 中用于保存文件的CFileDialog类函数

        CFileDialog fileDlg(FALSE);

        fileDlg.m_ofn.lpstrTitle="保存";

        fileDlg.m_ofn.lpstrFilter="Text Files(*.txt)\0*.txt\0ALL Files(*.)\0*.*\0\0";

        fileDlg.m_ofn.lpstrDefExt="txt";

        if(IDC_BUTTON1==fileDlg.DoModal())

        {

            CFile file(fileDlg.GetFileName(),CFile::modeCreate | CFile::modeWrite);

            file.Write("http:??",strlen("http:??"));

            file.Close();

        }

 

 

C#中用于连接数据库的连接字符串

private static String myConnectionString = "server=Localhost;database=data;UID=wyj;Password=123;Persist security info=True;database=data;";
