Since the sample source code is rather lengthy, please refer directly to the source code within    .   for more information. The sample shown there demonstrates various ways to interract with the M201_SP.DLL using the following API function calls:


Note that the sample application is designed for interraction by a developer, so for certain functionality such as setting the end-of-scan beep tone, values are hard-coded into the sample application code rather than having some form of entry box where a user of the application can enter specific values. However, some of the interface such as digital I/O does have numeric data entry boxes for an application user. These things were done in order to keep the overall complexity of the code to a minimum while still demonstrating some of the functionality.

Please see the simpler version of VisualBasic sample code  VBSamp.htm  for a view at what of the code and setting up the calls into the DLL should look like.
