The Eye4Software GPS toolkit allows software developers to add GPS functionality to their own programs without the need to have any knowledge on serial communications and GPS protocols like RS-232 and NMEA0183.
The product can be used in many programming environments, such as Visual Basic, Visual C++, Visual Studio.Net, Borland C++ Builder, Borland Delphi and VBA, but also web oriented applications such as ASP, ASP.NET and PHP, and all other programming environments that support ActiveX.
First you must have Visual C# .Net and the Eye4Software GPS Component installed on your computer. We will use Visual C# .Net 2008 in this document, but other versions from 2002 and up can be used. You can download the Eye4Software GPS Component here.
Start the Visual Studio IDE, and select the "New" => "Project" option from the "File" menu. The "New Project" dialog now appears, select the "Windows Application" option to generate a Windows GUI application.
In order to declare and create the objects from your Visual C# .Net application, you need to add a reference to the ActiveX object, by choosing the "Add Reference..." option from the "Project" menu. A list of components installed on the system is displayed. Just select the "COM" tab, and select the "Eye4Software GPS Toolkit 2.2", click "Select" and finally click "OK".
After adding the reference to the control, you can declare the objects like this:
private Gps objGps; private GpsConstants objGpsConstants;
The objects can be created in your code by double clicking on the Form you created, this will open the Formx_Load handler. Paste the following code in this function:
objGps = new Gps (); objGpsConstants = new GpsConstants ();
Below you can find the sourcecode from the Visual C# .Net demo as shipped with the project. Using this sample program, you can choose the serial port the GPS is connected to and start reading data from the GPS device. The software will display your current position, altitude, satellites in view, speed and course.
