我有7个表单，在表单内选择一个字符后应该能够打开和隐藏。
尝试这样：
public static ABCDE form;
public static BCI1 form1;
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
form = new ABCDE();
form1 = new BCI1();
form.Show();
form1.Show();
Application.Idle += new EventHandler(Application_Idle);
Application.Run();
}
static void Application_Idle(object sender, EventArgs e)
{
Message message;
while (!PeekMessage(out message, IntPtr.Zero, 0, 0, 0))
{
form.UpdateFrame();
form1.UpdateFrame();
}
}
将其设置为绿色：
long timeToBeGreenInMiliseconds = 10;
long timeWhenValue83WasSent;
bool shouldBeGreen;
void CallThisFunctionWhenValue83IsSent()
{
timeWhenValue83WasSent = stopwatch.ElapsedMilliseconds;
shouldBeGreen = true;
}
public void UpdateFrame()
{
if( shouldBeGreen )
{
pictureBox1.BackColor = Color.Green;
if( stopwatch.ElapsedMilliseconds - timeWhenValue83WasSent > timeToBeGreenInMiliseconds )
{
shouldBeGreen = false;
}
}
else
{
double cycleHz1 = 0.006;
double wave1 = Math.Sin((stopwatch.ElapsedMilliseconds * 2.0 * Math.PI) * cycleHz1);
if (wave1 > 0.0)
{
pictureBox1.BackColor = Color.Black;
}
else
{
pictureBox1.BackColor = Color.White;
}
}
}
