|
Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
|
Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
|

The NumericUpDownAcceleration object is used by the NumericUpDown control to optionally provide acceleration when incrementing or decrementing the control through a large quantity of numbers.
The following code example demonstrates how to use the NumericUpDownAcceleration class. To run this example, paste the following code into a form and call the InitializeAcceleratedUpDown method from the form's constructor or Load event handler. While the code is running, press and hold the up or down arrow to see the acceleration occur.
Private numericUpDown1 As NumericUpDown Private Sub InitializeAcceleratedUpDown() numericUpDown1 = New NumericUpDown() numericUpDown1.Location = New Point(40, 40) numericUpDown1.Maximum = 40000 numericUpDown1.Minimum = - 40000 ' Add some accelerations to the control. numericUpDown1.Accelerations.Add(New NumericUpDownAcceleration(2, 100)) numericUpDown1.Accelerations.Add(New NumericUpDownAcceleration(5, 1000)) numericUpDown1.Accelerations.Add(New NumericUpDownAcceleration(8, 5000)) Controls.Add(numericUpDown1) End Sub
private NumericUpDown numericUpDown1; private void InitializeAcceleratedUpDown() { numericUpDown1 = new NumericUpDown(); numericUpDown1.Location = new Point(40, 40); numericUpDown1.Maximum = 40000; numericUpDown1.Minimum = -40000; // Add some accelerations to the control. numericUpDown1.Accelerations.Add(new NumericUpDownAcceleration(2,100)); numericUpDown1.Accelerations.Add(new NumericUpDownAcceleration(5, 1000)); numericUpDown1.Accelerations.Add(new NumericUpDownAcceleration(8, 5000)); Controls.Add(numericUpDown1); }
