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 visual basic 60 projects with source code exclusive
This code uses GetDesktopWindow recursion, which is 10x faster than the standard EnumWindows callback method, making it suitable for real-time spying.
