{
SqlConnection conn = new SqlConnection(@Data Source = VISHAL-PC; Initial Catalog = arif; Integrated security = true);
SqlCommand cmd;
SqlDataReader dr;
string str;
int value1;
int value2;
int A;
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender,EventArgs e)
{
}
private void textBox3_TextChanged(object sender,EventArgs e)
{
}
private void timer1_Tick_1(object sender,EventArgs e)
{
}
private void timer1_Tick_2(object sender,EventArgs e)
{
{
if(textBox1.Text!=&& textBox2。 Text!=)
{
value1 = Convert.ToInt32(textBox1.Text);
value2 = Convert.ToInt32(textBox2.Text);
textBox3.Text = DateTime.Now.ToString();
str =;
str =插入kkk值(+ textBox1.Text +,+ textBox2.Text +,+ textBox3.Text +');
cmd = new SqlCommand(str,conn);
conn.Open();
dr = cmd.ExecuteReader();
value1 = value1 + 1;
value2 = value2 + 1;
textBox1.Text = value1.ToString();
textBox2.Text = value2.ToString();
conn.Close();
}
其他
{
break;
}
}
}
}
}
