| This example shows how to use the E-XD++ graphics component library visual aspects of development of industrial applications, the sample consists of three capable of independent operation of the controls, including: pumps, measuring tables and piston, E-XD++ visible graphical component library to support simple and precise timer control, can create other industrial components. as shown below: 
1. E-XD++ from initial design to any graphics on the canvas to start a separate set timer function independently, which means that if you want to make a graphics canvas to be allowed to move up and moving. 2. E-XD++ library itself with 100% VC ++ development from, all of the code through rigorous testing, to achieve the best performance for your application. 3. The solution has many of the world aerospace, defense, scientific research success in the simulation, industrial control and other aspects of use, has the best stability. 
System provides the following ready-made vector graphics, more complex figure than the official version can be provided by a professional graphic design program ShapeDesigner complex to design. 1). Industrial Equipment Components.

Here is the E-XD++ Visual Component Library source code version control system enterprise application development, the basic steps: 1. Design requires the monitoring system components: This step can be E-XD++ provides ShapeDesigner application to the design, this tool can directly be Microsoft Visio or ConceptDraw other professional graphics tools designed components into (SVG file) came in with, of course, you can also ShapeDesigner itself rich The basic graphic design needs to the monitoring system components. At design time, can easily design directly to the canvas element by Copy, Paste way to put a tool box on the left, as shown below (Note: This ShapeDesigner the source code itself, together with the E-XD++ provides the official version, can be customized as needed): 
When we design components of the composite components can also be a single definition of a number of sub-components to facilitate later identification and handling of the Key ID values that can later obtained directly by calling GetKeyID. 2. Design monitoring system needs a graphical interface: E-XD++ provides a special interface design tools DiagramEditor, in this tool, we can easily apply the above ShapeDesigner through a variety of monitoring system components designed to build a graphical interface. Interface in the structures, as required for specific components we can specify the Key ID value, the Key ID value for us in specific programs to control, for example, we can control the switch off and open, lights flashing and so on. We designed a graphical interface can be saved as a single xdg file, as shown below: (Note: This DiagramEditor the source code itself, together with the E-XD++ provides the official version can be customized as needed): 
3. Construction of the Frame control procedures: By E-XD++ visualization component library provides graphics integrated in Visual Studio's AppWizard (Application Creation Wizard) to automatically generate the framework code control system can be designed for the above We DiagramEditor xdg files into this program as resource file, when we need to load a design interface when calling the following function: LoadXdgFromResource (...); if we need to switch to the new interface, you can also call the function to load the new interface. Reference sample NetworkDemo. 4. Real-time data acquisition and processing: External data acquisition we can View the Window class or classes of timer to be collected, when the need to update the interface when the status of the components can be designed directly above us to get the Key value of the graphic elements or sub-component graphics. 5. Transaction processing: By overriding the appropriate virtual function to time a variety of transaction processing, for example, we only need to cover the following virtual functions CFOPCanvasCore class to respond to button events: virtual void DoButtonClickEvent (CFODrawShape * pShape, const int & nSel); HMI Demo example shows how to define a simple multi-page industrial control interface, as follows: 
The following example shows the E-XD++ development and simulation of industrial processes is extremely convenient and fast sex, such a complex sample application, development of the whole process requires only half a day, as follows: Status of a mobile oil drum: 
State II, grease, oil and grease table also shows the number of: 
State III, oiling is completed, instrument zero, the oil gun off, carried away with the trailer: 
The following sample program is to develop the basic steps: First, the design and simulation images of the industrial needs of the basic components: E-XD++ component library itself provides a large number of industrial components, while providing a professional design tool components ShapeDesigner, through the tools needed to easily design the components, we will put all the components designed in a tool box on the left Save the page fixed up, easy to use: 
Later use when you can directly drag and drop. Second, the design of industrial control and simulation of the screen: Through the accompanying E-XD++ products available DiagramEditor, can be designated industrial control and simulation to design appropriate screen, DiagramEditor provides a very sound and powerful features to ensure that the correct and efficient completion of a variety of high quality industrial design of the screen, in the design of the screen, we only need to drag the mouse the way through the steps of a good ready-made components in the design of structures can be dragged into the canvas, as shown below: 
When we collect data, we often need to refresh the canvas on the status of the various primitives, specifically for each component in the DiagramEditor provide 5 keywords, you can query by any one keyword to the specified component. Settings as shown below: 
The settings we will be the top element of the Key Value 1 is set to K2. Third, industrial structures and simulation programs need: By E-XD++ provides the AppWizard (application creation wizard), can automatically generate the IPC based on VC ++ application framework, to load any industrial screen, just above the first XDG industrial interface designed into the application file formed XDGRES resource file, and then you can call the following function: LoadXdgFromResource (IDR_MAIN, _T ("XdgRes"), FALSE); Of course, if you need to load a new industrial interface, also can call the function. Fourth, real-time data collection: View class through the timer function, regular data collection, if you need to update the picture elements, call control itself UpdateControl can, when you need to also update the time series components can be added directly to the CFODrawShapeList list, then call UpdateShapes that be.
