求小程序

[pgfpwx]

我需要一些简单有趣的小程序，最好是通过控件的事件来操作的，有思想也可以，不要小涉及数据库就行。谢谢了

[楼外楼]

你用来做什么，GDI+的要吗？

给你一个双色球的要不？

{
static void Main(string[] args)
{
int[] range = new int[33];
for (int i = 0; i < 33; i++)//初始化范围集合，从1到33
{
range[i] = i + 1;
}

int[] result = CreateRedBallNum(range, 6);

Console.WriteLine("RedBall is: ");

for (int i = 0; i < result.Length; i++)
{
Console.Write(result[i] + " ");
}
Console.WriteLine();

int BlueBall = CreateBlueBallNum();

Console.WriteLine("BlueBall is: ");

Console.WriteLine(BlueBall);

Console.ReadKey();
}

//取出不重复的6个数（红球）
static int[] CreateRedBallNum(int[] range, int count)
{
int[] result = new int[count];
Random random = new Random();
int index = 0;
int temp = 0;
for (int i = 0; i < count; i++)
{
index = random.Next() % (range.Length - i);
result[i] = range[index];
//将当前已使用过的数移至集合末尾，并且将末尾原来没有使用的数放到当前位置
temp = range[range.Length - 1 - i];
range[range.Length - 1 - i] = range[index];
range[index] = temp;
}

result = Sort(result);

return result;
}
//取蓝球
static int CreateBlueBallNum()
{
int result = 0;

Random r = new Random();

result = r.Next(1, 16);

return result;
}

//排序
static int[] Sort(int[] range)
{
for (int i = 0; i < range.Length; i++)
{
int temp = range[i];
int j = i;
while ((j > 0) && (range[j - 1] > temp))
{
range[j] = range[j - 1];
--j;
range[j] = temp;
}
}
return range;
}

}
}

呵呵，学生吧？

 private void textBox1_LostFocus(object sender, EventArgs e)//窗体的textbox控件上失去光标事件来触发
        {
            if (textBox1.Text != "")
            {
                DataSet ds = new DataSet();
                SqlConnection conn = new SqlConnection("数据库连接字符串");//连接数据库
                SqlDataAdapter adp = new SqlDataAdapter("sql语句").Fill(ds);//执行sql语句
                if (textBox1.Text == ds.Tables[0].Rows[0].ToString())//将查询出来的结果来与textbox中值来比对
                {
                    MessageBox.Show("查询到！");//比对结果如果一样
                }
                else
                {
                    MessageBox.Show("未查询到！");//比对结果如果不一样
                }
            }
            else
            {
                MessageBox.Show("比对值不能为空！");
                return;
            }
        }

用到部分数据库和简单控件事件，应该满足你要求吧~

[pgfpwx]

这个难啊！是给不懂程序的人看的

[睡神在睡觉]

private void button1_Click(object sender, EventArgs e)//单击button事件
{
   MessageBox.Show("单击成功！",MessageBoxButtons.OK,//指定按钮样式
MessageBoxIcon.Asterisk,//指定显示图片样式
MessageBoxDefaultButton.Button1);//指定默认按钮
   return;
}
