ReadyVisual Basic

Build it. Run it.

Drag controls from the toolbox, edit their properties, and double-click a control to create its VB event handler. Press F5 to run.

Browser preview supports

VB.NET event handlers and classic Control_Click names; variables; Sub and Function procedures; If / ElseIf / Else; For / Next; While; arithmetic, comparisons, and strings.

Text, Checked, Value, Enabled, Visible, Items.Add / Remove / Clear, SelectedIndex, Focus(), Me.Close(), MsgBox, and Debug.Print work. Helpers include Val, CStr, CInt, CDbl, Len, Trim, UCase, LCase, and IsNumeric.

Run on Windows

Export a ZIP with your VB code, generated designer, and a .NET 8 Windows Forms project. Open the .vbproj in Visual Studio with the .NET desktop workload, or run dotnet run with the .NET 8 SDK on Windows.

The browser runs a supported VB subset, not the Windows CLR. Native libraries, databases, files, timers, multiple forms, and full VB6 project imports require a desktop environment. Unsupported code is reported in Output. MsgBox displays a browser dialog and returns OK immediately; execution continues.
