Q: How to get started with Visual Prolog?
A: Start by reading Getting Started.

Q: Which platforms does Visual Prolog support?
A: Visual Prolog supports those Windows platforms that Microsoft supports.

Q: Are there any plans for supporting Linux or any Unix platforms?
A: There are no plans for supporting Linux or any Unix platforms.

Q: What are the differences between Visual Prolog and traditional Prolog?
A: The differences between traditional Prolog and Visual Prolog can be broadly divided into these categories:
  1. Program structure differences
    There are distinct, yet easy to understand differences between the structure used in traditional Prolog and that used in Visual Prolog. It essentially comprises of understanding how to mark out the declarations from the definitions, and to indicate the main Goal that the program has to seek using specific keywords.
  2. File considerations
    Visual Prolog gives various facilities to organize the structure of the program into different kinds of files.
  3. Scope access issues
    A Visual Prolog program can pick up functionality developed in other modules using a concept called scope identification.
  4. Object orientation
    A Visual Prolog program can be written as an object-oriented program, using classic object oriented features.

See Fundamental Visual Prolog tutorial for details.


Q: Where can I find examples and demos?
A: Visual Prolog examples and demos are available in several ways:

Visual Prolog distribution includes sample projects that can be installed from the Integrated Development Environment (IDE) with the help of the command Help -> Install Examples.

This site contains examples provided by members of Visual Prolog Community.

Visual Prolog tutorials discuss examples that might be downloaded. You will be suggested to download source files while reading these tutorials. For example, the tutorials Fundamental Prolog Part 1, Fundamental Prolog Part 2, and Fundamental Visual Prolog discuss a well-known prolog family example in details.


Q: How do I make and use COM objects?
A: Visual Prolog is COM compatible, the IDE can generate necessary wrap classes and interfaces based on a type library supplied with the COM object.

Q: Is it possible to use a DLL, created by Visual Prolog, in a Microsoft.NET project?
A: Yes. It is possible. Such DLL created by Visual Prolog should have predicates exported with stdcall calling convention. And VB.NET or C#.NET code should call it in the same manner as invocation of an API function.

You are welcome to download How to Use Visual Prolog DLL from .Net example that creates a Visual Prolog DLL and shows how a program, created by Visual Basic .NET, can call a predicate, exported by this DLL.


Q: Can I use my registration in the Discussion Forum to have Registered Visual Prolog Personal Edition and vice versa?
A: No. Registration in the Discussion Forum and registration of Visual Prolog Personal Edition are two different registrations.

To register your Personal Edition you need to use the WEB -> Register menu item in the Integrated Development Environment (IDE).


Q: Can I create a Sudoku solver with Visual Prolog?
A: Yes,
