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.
Fields
Properties
- CaseSensitive
Gets or sets a boolean value that indicates whether
VbScriptParser
should perform case-sensitive analysis of its content.
