Visual Basic 6.0 Projects With Source Code [WORKING]

The call came in at 4:45 PM on a Friday. The kind of call that makes senior developers vanish into thin air, leaving only a cloud of dust and a "Out of Office" auto-reply.

"Arthur, we have a Code Red," my manager, Dave, said, leaning over my cubicle wall. "The inventory system at the logistics warehouse in Jersey just crashed. They can’t ship anything until the 'Process Manifest' button works again."

"Which system?" I asked, spinning my chair around. "The new ASP.NET Core web app?"

Dave shook his head grimly. "No. The legacy backend. The one that runs on the Windows 98 machine in the basement." visual basic 6.0 projects with source code

I felt a chill run down my spine. "You don't mean..."

"I do. Project InventoryMaster_v6_Final_FINAL_RealFinal.exe. It’s a VB6 app, Arthur. And you’re the only one left who remembers how to open an .frx file."

Teachers and students often modify existing VB6 projects to learn specific concepts. The call came in at 4:45 PM on a Friday

Purpose: Secure application with user authentication, password hashing (simple XOR), and access levels (Admin/User).
Database Table (Users):
UserID, Username, PasswordHash (Text), UserRole (Text).

Key Source Code (Login validation):

Private Function SimpleHash(plainText As String) As String
    Dim i As Integer
    Dim result As String
    For i = 1 To Len(plainText)
        result = result & Chr(Asc(Mid(plainText, i, 1)) Xor 123)  ' XOR obfuscation
    Next i
    SimpleHash = result
End Function
Private Sub cmdLogin_Click()
Dim rs As Recordset
Set rs = db.OpenRecordset("SELECT * FROM Users WHERE Username='" & txtUsername.Text & "'")
If Not rs.EOF Then
If rs!PasswordHash = SimpleHash(txtPassword.Text) Then
MsgBox "Welcome " & rs!Username & " (Role: " & rs!UserRole & ")"
' Load main form based on role
If rs!UserRole = "Admin" Then frmAdmin.Show Else frmUser.Show
Unload Me
Else
MsgBox "Incorrect password."
End If
Else
MsgBox "User not found."
End If
End Sub

ActiveX controls that are 32-bit only will fail on 64-bit VB6 IDE. Solution: Run VB6 in 32-bit compatibility mode or use a VM. ActiveX controls that are 32-bit only will fail

Visual Basic 6.0 (VB6), released by Microsoft in 1998, remains a significant IDE and programming language for rapid application development (RAD) of Windows desktop applications. Despite its end of mainstream support, countless legacy enterprise applications, educational tools, and small utility software still rely on VB6. This report details eight classic VB6 project categories, each with its complete source code structure, core logic, and user interface design. The goal is to serve as a reference for developers creating, maintaining, or modernizing VB6 applications.
