4.7 系统维护模块
系统维护模块包括：系统日志，系统初始化，数据备份
数据备份：
主要代码：
//备份
private void button3_Click(object sender, EventArgs e)
{
try
{
//还原数据库
string str = "use master restore database LvXiang from Disk='" + textBox1.Text.Trim() + "'";
SqlConnection conn = BaseClass.DBCon();
conn.Open();
SqlCommand cmd = new SqlCommand(str, conn);
cmd.ExecuteNonQuery();
if (MessageBox.Show("恢复成功", "提示", MessageBoxButtons.OK, MessageBoxIcon.Exclamation) == DialogResult.OK)
{
this.Close();
}
}
catch (Exception)
{
MessageBox.Show("数据库还原失败！", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
}
系统日志：
主要代码：
private void frmSystemLog_Load(object sender, EventArgs e)
{
string sql = "select DengLuMing as '登录名',DengLuShiJian as '登录时间',TuiChuShiJian as '退出时间' from XiTongRiZhiBiao";
dataGridView1.DataSource = BaseClass.FindData(sql).Tables[0]; //调用基础类中的FindData()方法实现查找功能
}
三．总结（心得）：
本软件采用三层架构制作，已具备基本功能（用户登录，权限管理，进货，出货，报表，查询等功能）软件运行基本无误。通过实验周的学习与制作，我从中学到许多东西，我还非常感谢同学们的帮助。
