[RESOLVED] Monitor Process Creation and Deletion without WMI

[stronius]

The following is an example of monitoring opened or closed processes without using WMI. First you copy an initial processes list to array, then based on a timer, can call the checkProcess() function which will compare the latest processes list with your original, and record any opened or closed processes into a variable called processActivity.

First, variable declarations...

    Dim processesList As String 'Containts initial processes list.
    Dim processActivity As String 'Containts all opened / closed processes.
    Dim processesAtStart As New ArrayList 'Original Processes List as ArrayList. (Used to Compare)
    Dim processesCheck As New ArrayList 'Latest Processes List as ArrayList. (Used to Compare)

Then, I create an initial processes list in the form of string, and of an arrayList (So that it can be compared) ...

        Dim proc As New Process
        For Each proc In Process.GetProcesses
            Try
                processesList = processesList + proc.MainModule.ModuleName + " - " + proc.MainModule.FileName + ControlChars.NewLine
                processesAtStart.Add(proc.MainModule.ModuleName + " - " + proc.MainModule.FileName)
            Catch ex As Exception
                processesList = processesList + proc.ProcessName + ControlChars.NewLine
                processesAtStart.Add(proc.ProcessName)
            End Try
        Next
        proc.Dispose()

Next, I create a procedure, which will be called based on a timer to check the latest processes list with the initial processes list and record any opened or closed processes...

    Public Sub processCheck()

        'Gets latest processes list and compares it to initial list.
        processesCheck.Clear()

        Dim proc As New Process
        For Each proc In Process.GetProcesses
            Try
                processesCheck.Add(proc.MainModule.ModuleName + " - " + proc.MainModule.FileName)
            Catch ex As Exception
                processesCheck.Add(proc.ProcessName)
            End Try
        Next
        proc.Dispose()

        'Convert list into array to be compared
        Dim latestProcesses() As String = DirectCast(processesCheck.ToArray(GetType(String)), String())
        Dim initialProcesses() As String = DirectCast(processesAtStart.ToArray(GetType(String)), String())

        'Find Closed Processes
        For Each item As String In initialProcesses
            If (Array.IndexOf(latestProcesses, item) = -1) Then
                processActivity = processActivity + ControlChars.NewLine + "Closed : " + item
                processesAtStart.Remove(item)
            End If
        Next
        'Find Opened Processes
        For Each item As String In latestProcesses
            If (Array.IndexOf(initialProcesses, item) = -1) Then
                processActivity = processActivity + ControlChars.NewLine + "Opened : " + item
                processesAtStart.Add(item)
            End If
        Next

    End Sub

Enjoy! Use my code as you like and I appreciate suggestion and improvements!
