Q: What are the main differences between a console and a graphical application?
A: A console application, like those which can be created by using xConsole, usually has a linear development, according to the principle that in every moment the user can do only what is supposed to do by the program; graphical applications, on the contrary, are event-oriented: the user presses a button or inputs a string, generating an event that must be taken care by the program - in this way, there is a non-linear execution.

Q: What advantanges does a console application offer?
A: Text-mode programs are usually easier to understand when compared to their graphical counterparts; they are lighter and can be visualized on every kind of terminal (e.g. using a Telnet Server). Moreover, many times professional users prefer running programs from a Dos console.

Q: My program, created using xConsole, works correctly only when run from a Dos prompt; why?
A: It is necessary to use the program ConsoleMode (shipped together with xConsole Active-X and described in the manual) to change execution mode from "graphical" to "console", every time that the application is recompiled.

Q: What are the differences between the registered and unregistered versions of the control?
A: The registered version does not pop-up the initial graphical prompt, so the programs created run correctly under a Telnet Server.

Q: I have installed the registered version of the control and all at once the demo program do not work anymore; what happens?
A: This is the correct behaviour - the registered control has licence information which are different from those embedded in the demo programs; just re-compile the demo under Visual Basic to make it work with the new control (remove and add again the control). For the Visual C++ demo follow these steps:

• open (Ufrom Resources) the Dialog IDD_XCDEMO_DIALOG;
• remove the xConsole control;
• add the control again by using the Gallery, as explained in the manual; the support classes (which have already been created) are grayed out; close the gallery;
• select the control from the palette and add it to the dialog;
• recompile the application.

Q: Can I use xConsole under any developmente environment?
A: Yes, if the environment supports Active-X controls. xConsole was successfully tested under Visual Basic and Visual C++.

Q: What does it mean that each copy of xConsole is "serialized"?
A: When a customer buys xConsole, a personalized Active-X with a unique serial code is compiled for him; this serial code is kept together with the personal data of the customer: if the Active-X is passed to other people together with the licence file without authorization, we can discover who owns that copy that violated the licence.
