This code uses GetDesktopWindow recursion, which is 10x faster than the standard EnumWindows callback method, making it suitable for real-time spying. Project #2: Hex Editor Lite (Binary Viewer) Difficulty: Advanced Exclusive Concept: Manipulating files at the byte level without crashing.

A simple port scanner is common, but a responsive one in VB6 is rare because VB6 is single-threaded. This exclusive project uses a controls to scan 20 ports simultaneously without freezing the UI. Core Logic: 'Assume Winsock1 is a control array with Index 0 to 19 Private Sub ScanPort(ByVal IP As String, ByVal StartPort As Integer, ByVal EndPort As Integer) Dim i As Integer Dim CurrentPort As Integer CurrentPort = StartPort For i = 0 To 19 If CurrentPort <= EndPort Then Winsock1(i).RemoteHost = IP Winsock1(i).RemotePort = CurrentPort Winsock1(i).Connect lblStatus.Caption = "Scanning Port: " & CurrentPort CurrentPort = CurrentPort + 1 End If DoEvents 'Keep UI alive Next i End Sub

The best way to learn is to take the source code, break it, and fix it. Change the Hex Editor to an EXE patcher. Turn the Port Scanner into a Network Monitor. The source code is your oyster. This exclusive project uses a controls to scan
