ASP Exercises

Practise a refusal case before adding another feature.

How it works

Start from the fictional three-seat workshop. Predict the final state after reserving two seats, refusing a request for two more, and accepting the final single seat. The task is to preserve non-negative capacity and unchanged state on refusal. Try writing the small state rule before reading this worked implementation.

Use the separate Windows lab

This is a legacy-maintenance course. Classic ASP uses IIS and VBScript; ASP.NET Web Pages uses .NET Framework and Razor. Neither runs in PHP, Apache or Bhylu’s browser playground. The reviewed baseline is 32-bit IIS Express 10.0.2001, .NET Framework 4.8, Web Pages / Razor 3.2.9 and the Windows VBScript engine. ADO database examples use the actual 32-bit Jet OLE DB 4.0 provider, not SQL Server or XAMPP MySQL.

Download download-lab.mjs into a separate empty learning folder. Run node download-lab.mjs to fetch hash-checked source files into a new bhylu-asp-lab folder, then cd bhylu-asp-lab and node run-lab.mjs --start. Before deployment, local preview uses node download-lab.mjs http://127.0.0.1:8000/examples/asp/. The source downloader refuses an existing destination. Review its source before running it.

The foreground launcher needs your own 32-bit IIS Express installation with Classic ASP, .NET Framework 4.8 and the VBScript engine available. It downloads the three pinned Web Pages packages from NuGet into its private cache, binds only localhost on port 8142 and stops when you press Ctrl+C. Keep its console open. Visit http://localhost:8142/exercises.asp. It does not install IIS, enable Windows features, change Apache/PHP/MySQL, or publish any files. See the bundled README.txt for manual setup and test boundaries.

Each complete Classic ASP source requires the supplied Global.asa acknowledgement; Web Pages uses _PageStart.cshtml. Database and file examples create owned temporary files only under this private lab’s blocked App_Data folder. Sources are public text downloads; do not upload them as executable teaching endpoints on Bhylu.

Lesson excerpt

Dim seats, accepted
seats = 3
accepted = 0
Sub TryReserve(ByVal quantity)
    If quantity < 1 Or quantity > seats Then Exit Sub
    seats = seats - quantity
    accepted = accepted + 1
End Sub
TryReserve 2
TryReserve 2
TryReserve 1
Response.Write "Seats: " & seats & vbLf
Response.Write "Accepted: " & accepted

Expected result

Seats: 0
Accepted: 2

The middle request is refused, so it does not reduce the count. This request-local exercise teaches the invariant, while the project applies a database predicate and transaction. Add empty, zero and invalid-string cases only after defining a parsing contract.
