Visual Basic Examples on how to connect the DLL to the terminal using XRML
XRML
The XRML works with screens that are sent to the terminal. It can be compared with HTML in the sense that it asks the terminal for a screen and the PC sends it. However when the terminal asks for a screen from the PC, the PC may send the screen or other screens, such as, for example in case of error.
The screens that the PC send may be valid for a temporary period of time. In other words, the screen may be valid just for a few seconds or for ever.
To send data to the PC, the terminal sends the screen back to the PC. The program of the PC must run exactly the same code used to generate the screen. Also, the DLL will update the variables at the same time.
Let's see how it works.
