ASP Razor Visual Basic

Read a legacy .vbhtml template without confusing it with .asp VBScript.

How it works

Razor Visual Basic uses VB.NET syntax and a .NET runtime. It has typed variables and language constructs different from VBScript. The example combines a typed count, If and For Each. It is included for maintenance coverage, not as a claim that modern ASP.NET Core supports unchanged .vbhtml views.

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/razor-visual-basic.vbhtml. 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.

@Code
    Layout = Nothing
    Dim seats As Integer = 2
    Dim names = New String() {"Mending", "Buttons"}
End Code
<div id="result">
@If seats > 0 Then
    @<p>Seats: @seats</p>
End If
@For Each name In names
    @<span>@name</span>
Next
</div>

Lesson excerpt

@Code
    Layout = Nothing
    Dim seats As Integer = 2
    Dim names = New String() {"Mending", "Buttons"}
End Code
<div id="result">
@If seats > 0 Then
    @<p>Seats: @seats</p>
End If
@For Each name In names
    @<span>@name</span>
Next
</div>

Expected result

Seats: 2 Mending Buttons

The @< syntax introduces an HTML fragment inside a VB control block. The compiler and runtime are .NET Framework components, not the VBScript engine used by Classic ASP. Both versions are executed separately in the review.
