Examples

Here is how to declare a VbScriptParser and assign it to the edit control from the C# code:

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        var parser = new Alternet.Syntax.Parsers.Advanced.VbScriptParser();
        var edit = new Alternet.Editor.SyntaxEdit();
        edit.Parent = this;
        edit.Lexer = parser;

        string fileName = "myfile.vbs";
        if (System.IO.File.Exists(fileName))
        {
            parser.FileName = fileName;
            edit.LoadFile(fileName);
        }
    }
}

Here is how to declare a VbScriptParser and assign it to the edit control from the Visual Basic code:

Partial Public Class Form1
    Inherits Form

    Public Sub New()
        InitializeComponent()
    End Sub

    Private Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs)
        Dim parser = New Alternet.Syntax.Parsers.Advanced.VbScriptParser()
        Dim edit = New Alternet.Editor.SyntaxEdit()
        edit.Parent = Me
        edit.Lexer = parser
        Dim fileName As String = "myfile.vbs"

        If System.IO.File.Exists(fileName) Then
            parser.FileName = fileName
            edit.LoadFile(fileName)
        End If
    End Sub
End Class

Remarks

VbScriptParser is a non-visual component designed to perform syntax highlighting for the Visual Basic Script language. This parser supports full syntax analysis of the Visual Basic Script code. When linked to the SyntaxEdit or TextEditor controls, this parser drives additional features such as code completion, code outlining, code formatting, and underlying syntax errors and warnings.

Here are some of the essential features provided by the VbScriptParser:

Syntax Highlighting
IntelliSense (Code completion)
Code Outlining
Structure guidelines
Formatting a selected block of text or the whole document

Constructors

VbScriptParser(): Initializes a new instance of the VbParser class with default settings.
