* Example program:
*   ContAcqVoltageSamples_IntClk
*
* Category:
*   AI
*
* Description:
*   This example demonstrates how to acquire a continuous amount of data using
*   the DAQ device's internal clock.
*
* Instructions for running:
*   1.  Select the physical channel corresponding to where your signal is input
*       on the DAQ device.
*   2.  Enter the minimum and maximum voltage values.Note: For better accuracy,
*       try to match the input range to the expected voltage level of the
*       measured signal.
*   3.  Set the rate of the acquisition.Note: The rate should be at least twice
*       as fast as the maximum frequency component of the signal being acquired.
*       Also, in order to avoid Error -50410 (buffer overflow) it is important
*       to make sure the rate and the number of samples to read per iteration
*       are set such that they don't fill the buffer too quickly. If this error
*       occurs, try reducing the rate or increasing the number of samples to
*       read per iteration.
*
* Steps:
*   1.  Create a new analog input task.
*   2.  Create an analog input voltage channel.
*   3.  Set up the timing for the acquisition. In this example, we use the DAQ
*       device's internal clock to continuously acquire samples.
*   4.  Call AnalogMultiChannelReader.BeginReadWaveform to install a callback
*       and begin the asynchronous read operation.
*   5.  Inside the callback, call AnalogMultiChannelReader.EndReadWaveforme to
*       retrieve the data from the read operation.  
*   6.  Call AnalogMultiChannelReader.BeginMemoryOptimizedReadWaveform
*   7.  Dispose the Task object to clean-up any resources associated with the
*       task.
*   8.  Handle any DaqExceptions, if they occur.
*
*   Note: This example sets SynchronizeCallback to true. If SynchronizeCallback
*   is set to false, then you must give special consideration to safely dispose
*   the task and to update the UI from the callback. If SynchronizeCallback is
*   set to false, the callback executes on the worker thread and not on the main
*   UI thread. You can only update a UI component on the thread on which it was
*   created. Refer to the How to: Safely Dispose Task When Using Asynchronous
*   Callbacks topic in the NI-DAQmx .NET help for more information.
*
* I/O Connections Overview:
*   Make sure your signal input terminal matches the physical channel I/O
*   control. In the default case (differential channel ai0) wire the positive
*   lead for your signal to the ACH0 pin on your DAQ device and wire the
*   negative lead for your signal to the ACH8 pin on you DAQ device.  For more
*   information on the input and output terminals for your device, open the
*   NI-DAQmx Help, and refer to the NI-DAQmx Device Terminals and Device
*   Considerations books in the table of contents.
*
* Microsoft Windows Vista User Account Control
*   Running certain applications on Microsoft Windows Vista requires
*   administrator privileges, 
*   because the application name contains keywords such as setup, update, or
*   install. To avoid this problem, 
*   you must add an additional manifest to the application that specifies the
*   privileges required to run 
*   the application. Some Measurement Studio NI-DAQmx examples for Visual Studio
*   include these keywords. 
*   Therefore, all examples for Visual Studio are shipped with an additional
*   manifest file that you must 
*   embed in the example executable. The manifest file is named
*   [ExampleName].exe.manifest, where [ExampleName] 
*   is the NI-provided example name. For information on how to embed the manifest
*   file, refer to http://msdn2.microsoft.com/en-us/library/bb756929.aspx.Note: 
*   The manifest file is not provided with examples for Visual Studio .NET 2003.
