ASP Runner (Browser)

Keyboard Shortcuts

• Ctrl+Enter — Run the current VBScript code

Writing Code

Write VBScript inside <% ... %> tags, just like Classic ASP. Use Response.Write to output HTML. The editor has syntax highlighting and auto-closing brackets.

Samples

Click any sample button above the editor to load a ready-to-run snippet:

Each sample is a complete ASP page with comments, spacing, and the classic ASP pattern of mixing VBScript code blocks with HTML. Click any to explore:

• Hello World — the simplest Response.Write
• QueryString — reading URL parameters with Request.QueryString
• Contact Form — POST handling with server-side validation
• Class — VBScript classes with Property Get/Let
• Select Case — branching logic, ranges, comparisons
• Dictionary — key-value storage with Scripting.Dictionary
• RegExp — pattern matching with regular expressions
• Arrays — fixed-size and dynamic arrays
• Functions — Sub/Function definitions, bubble sort
• Date/Time — Now, DateAdd, DateDiff, WeekdayName, MonthName
• Data Table — HTML table with alternating row colors
• Strings — Trim, UCase, Mid, InStr, Replace, Split, Join
• Server — HTMLEncode, URLEncode, CreateObject, Dictionary

Tip: Samples use <%= expression %> to output values directly in HTML — no messy Response.Write for static markup!

Request Simulation

The Request panel below the editor lets you set Request.Method, Request.QueryString, Request.Form, and Request.Cookies before running your code.

Output Tabs

• HTML Output — rendered iframe of your Response.Write output
• Errors — simplified Python/VBScript error messages
• Log — server-side log output

Auto-Save

The editor content and request fields are automatically saved to localStorage and restored when you return.

Limitations

This browser runner stubs out modules that depend on native libraries or OS features: POP3, IMAP, MSXML, CDO. The following work in full fidelity: Response, Request, Server, Session, Application, ADODB (SQLite), JSON, file system operations, zip, crypto (bcrypt), image (Pillow), PDF (fpdf2), and the VBScript VM interpreter.
