Windows Form Doesn't Show C# Timer

问题:

Code:

while ( int_Timer > 0 )
{
     int int_Ticks = 0;

     if ( int_Ticks < 100)
     {
         int_Ticks++;
     }

     if (int_Ticks == 100)
     {
         int_Timer--;
         lbl_Timer.Text = int_Timer.ToString();
     }
}

So I basically tried to make a timer however, since I implemented this code the form doesn't appear in the taskbar. In fact the only indication is the Visual Studio Debug running.

Go into the Windows Forms toolbox. Under "Component", find "Timer". Drag/drop one onto your form. It won't show up where you dropped it (it's non-visible), but it will show up in a pane below.

Go to the properties of your new timer (named "timer1" by default) and change:

• Enable to true
• Interval to 1000 milliseconds, i.e., one second

Double-click on the timer1 Timer component on your form designer (at the bottom). That will create a handler for the default event (Tick).

Make that code look like:

 private int _count = 0;
 private void timer1_Tick(object sender, EventArgs e)
 {
     ++_count;
     Tlbl_Timer.Text = _count.ToString();
 }

You should see your label start counting at 1 and going up until it overflows (somewhat north of two billion).
