Visual Basic 60 Projects With Source Code Exclusive

Requirements: Add 1 ListBox (lstProcess), 1 CommandButton (cmdKill), and 1 Timer (Timer1, Interval=1000).

' Variable to hold the process ID
Dim ProcID As Long
Private Sub Form_Load()
    ' Populate the list on startup
    Call RefreshProcessList
End Sub
Private Sub Timer1_Timer()
    ' Refresh the list every second to show current state
    Call RefreshProcessList
End Sub
Private Sub cmdKill_Click()
    ' Warning before killing
    If MsgBox("Are you sure you want to kill this process?", vbCritical + vbYesNo) = vbYes Then
        If lstProcess.ListIndex <> -1 Then
            ' AppActivate tries to switch to the app, sending close command
            On Error Resume Next
            AppActivate lstProcess.List(lstProcess.ListIndex)
            SendKeys "%F4" ' Alt + F4
' If that fails, we can attempt a harder kill via Shell (Advanced)
            ' Shell "taskkill /f /im " & lstProcess.List(lstProcess.ListIndex), vbHide
            MsgBox "Termination command sent.", vbInformation
        End If
    End If
End Sub
Private Sub RefreshProcessList()
    ' This is a simplified method using the "Tasks" visible to AppActivate
    ' For a true deep system scan, API calls (CreateToolhelp32Snapshot) are needed.
lstProcess.Clear
' Note: VB6 cannot natively list ALL processes without complex Windows APIs.
    ' For this "exclusive" demo, we will use a WMI script object.
    ' You must add a Reference to "Microsoft WMI Scripting V1.2 Library" (Project -> References).
Dim wmi As Object
    Dim procs As Object
    Dim proc As Object
Set wmi = GetObject("winmgmts:\\.\root\cimv2")
    Set procs = wmi.ExecQuery("Select * from Win32_Process")
For Each proc In procs
        lstProcess.AddItem proc.Name & " (PID: " & proc.ProcessId & ")"
    Next
End Sub

You need to add a reference to CAPICOM (Microsoft Cryptographic API).

'Requires: Project -> References -> "COM+ 1.0 Type Library" or "CAPICOM 2.0"
Private Function EncryptString(ByVal PlainText As String, ByVal Password As String) As String
Dim EncryptedData As New CAPICOM.EncryptedData
EncryptedData.Algorithm.Name = CAPICOM_ENCRYPTION_ALGORITHM_CAPICOM_ENCRYPTION_ALGORITHM_3DES
EncryptedData.SetSecret Password
EncryptedData.Content = PlainText
EncryptString = EncryptedData.Encrypt(CAPICOM_ENCODING_BASE64)
End Function
Private Function DecryptString(ByVal CipherText As String, ByVal Password As String) As String
On Error GoTo BadPassword
Dim EncryptedData As New CAPICOM.EncryptedData
EncryptedData.Algorithm.Name = CAPICOM_ENCRYPTION_ALGORITHM_CAPICOM_ENCRYPTION_ALGORITHM_3DES
EncryptedData.SetSecret Password
EncryptedData.Decrypt CipherText
DecryptString = EncryptedData.Content
Exit Function
BadPassword:
DecryptString = "ERROR: Wrong Password"
End Function visual basic 60 projects with source code exclusive
'Save to file
Private Sub SaveVault()
Dim ff As Integer
ff = FreeFile
Open App.Path & "\vault.dat" For Binary As #ff
Put #ff, , EncryptString(Text1.Text, MasterPass)
Close #ff
End Sub

Exclusive Insight: This doesn't store the password hash; it uses the password as a key. If you lose the master password, the data is gone forever—real security. You need to add a reference to CAPICOM

Difficulty: Advanced
Key Features:

Why it’s exclusive:
Most VB6 chat examples are broken. This one includes connection retry logic, heartbeat signals to detect disconnections, and unicode support (via byte arrays).

Architecture Highlight:

Packet Structure:

[Command: 2 bytes][Length: 4 bytes][Payload]

Commands: PM (private msg), BC (broadcast), FT (file transfer request)

' Simplified pseudocode - actual device uses HID API
Public Function GetTemperature() As Single
    ' DLL calls to hid.dll and setupapi.dll
    ' Find device by Vendor ID 0x0C45 (Microchip)
    ' Read feature report byte 0x01
    ' Convert bytes to temperature
    GetTemperature = 23.5 ' example
End Function

Exclusive Value: Includes a scheduler to run every 15 minutes and generate daily PDF reports using ReportViewer control. Exclusive Insight: This doesn't store the password hash;
