窗口创建句柄时错误
下面是我的代码，我在一个窗体中创建了两个system.timer.timer，但是当关闭窗体时，如果任意一个timer.Enabled=true，则会报错，“用户代码未处理Win32Exception：窗口创建句柄时错误”，报错位置是两个timer的Elapsed事件（两个事件都有可能）中的this.textBox3.Text = hour1.ToString()这句话（就是为textbox.text赋值这句话），以下是代码：
private void button9_Click(object sender, EventArgs e)
{
timer2.Interval = 1;//表示每1ms刷新一次时钟，每次刷新50个毫秒
timer2.Elapsed += new ElapsedEventHandler(timer2_Elapsed);
timer2.AutoReset = true;
timer2.Enabled = true;
timer4.Interval = 1;//表示每1ms刷新一次时钟，正常是次刷新1个毫秒
timer4.Elapsed += new ElapsedEventHandler(timer4_Elapsed);
timer4.AutoReset = true;
timer4.Enabled = true;
}
void timer2_Elapsed(object sender, ElapsedEventArgs e)
{
if (second_mile < 1000)
{
second_mile += 50;
this.textBox_Sec.Text = second.ToString();
this.textBox_Min.Text = minute.ToString();
this.textBox_Hour.Text = hour.ToString();
this.textBox_milesecond.Text = second_mile.ToString();
}
else
{
second_mile = 0;
if (second < 59)
{
second += 1;
this.textBox_Sec.Text = second.ToString();
this.textBox_Min.Text = minute.ToString();
this.textBox_Hour.Text = hour.ToString();
this.textBox_milesecond.Text = second_mile.ToString();
}
else
{
second = 0;
if (minute < 59)
{
minute += 1;
this.textBox_Sec.Text = second.ToString();
this.textBox_Min.Text = minute.ToString();
this.textBox_Hour.Text = hour.ToString();
this.textBox_milesecond.Text = second_mile.ToString();
}
else
{
minute = 0;
hour += 1;
this.textBox_Sec.Text = second.ToString();
this.textBox_Min.Text = minute.ToString();
this.textBox_Hour.Text = hour.ToString();
this.textBox_milesecond.Text = second_mile.ToString();
}
}
}
}
void timer4_Elapsed(object sender, ElapsedEventArgs e)
{
if (second_mile1 < 1000)
{
second_mile1 += 1;
this.textBox3.Text = hour1.ToString();
this.textBox4.Text = minute1.ToString();
this.textBox5.Text = second1.ToString();
this.textBox6.Text = second_mile1.ToString();
}
else
{
second_mile1 = 0;
if (second1 < 59)
{
second1 += 1;
this.textBox3.Text = hour1.ToString();
this.textBox4.Text = minute1.ToString();
this.textBox5.Text = second1.ToString();
this.textBox6.Text = second_mile1.ToString();
}
else
{
second1 = 0;
if (minute1 < 59)
{
minute += 1;
this.textBox3.Text = hour1.ToString();
this.textBox4.Text = minute1.ToString();
this.textBox5.Text = second1.ToString();
this.textBox6.Text = second_mile1.ToString();
}
else
{
minute1 = 0;
hour1 += 1;
this.textBox3.Text = hour1.ToString();
this.textBox4.Text = minute1.ToString();
this.textBox5.Text = second1.ToString();
this.textBox6.Text = second_mile1.ToString();
}
}
}
}
[解决办法]
关闭窗体前，先将timer设置为false，因为关闭窗体时会销毁对象，你timer再访问的话就报错
[解决办法]
。。你都先dispose了
