I would love a 2nd set of eyes because what I need to accomplish has to be easy I am just over thinking this thing.

First some Background: I have a program that uses Phidgets RFID readers and a weight sensor, All of this and the current state of the program works perfectly.

When the RFID reader reads a tag it makes sure the min. weight is also present and then launches a macro in another program. If the Tag goes out of range and/or the weight on the scale goes below the min. it stops, rinses and repeats when a tag is scanned again.

FYI this whole apparatus is for Behavioral Pigeon research in a college Psychology Dept. We use an industry standard program for our research but is has no customization or autonomy. That is where my app comes in, simply put it listens for the RFID and weight and if given the go it passes the info to the Psych program via simple macros the psych program will accept. The whole thing is ties to a contraption that allows the pigeons to choose when they want to run experiments for us in return for yummy birdseed rewards..... Anyway

Now for the Issue:

We now want to add a contingency to lockout greedy pigeons who has began guarding the platform so only they can access the system for food (The RFID tag is on each pigeons ankle so the system recognizes them by ID/Name)

So I added a timer that we can customize with a text box IE: 30000ms, then tied it to a checkbox so we can turn the condition on and off. That works fine. What I need is when the pigeon leaves and the system resets everything it starts the timer, If that same RFID tag is scanned again within that timer it ignores it and simply logs the scan but does not run the macro. If a different RFID scans it just runs as normal.

Here is the current Sub that handles RFID Tags and works as normal:

Code:
 'Tag event handler...we'll display the tag code in the field on the GUI
    Public Sub PhidgetRfidTag(ByVal sender As Object, ByVal e As TagEventArgs) Handles PhidgetRfid.Tag

        MinimumStartThreshhold = CInt(FormOpt.TxtBxMinStart.Text)
        gramData = CInt(ActiveWeight.Text)

        LabelTagLive.Text = e.Tag

        If e.Tag IsNot Nothing Then
            ValidTag = True
        Else
            ValidTag = False
        End If

        If gramData > MinimumStartThreshhold Then
            ValidWeight = True
        Else
            ValidWeight = False
        End If

        If ValidTag And ValidWeight = True Then
            UpdateTextBoxNormal()  '-Updates the DataGrid with Subject and RFID info.
            MacroExecute()            '-Runs the Macro to Launch Med-PC IV
        Else
        End If

    End Sub
Pretty Basic, no shock it works fine

So when I add the conditions for watching if a tag string is locked out I used the following changes with odd results...

I made a simple sub to compare the incoming string to the last:
Code:
    Public Sub LockoutCompare()
        Dim TagScanned = LabelTagCurrent.Text
        Dim TagLast = LabelTagLast.Text

        If String.Equals(TagScanned, TagLast) = True Then
            Lockout = True
        Else
            Lockout = False

        End If

    End Sub
I have gotten mixed info on how to use the String.Equals function should I represent the boolean answers as True/False or 0/1? or does it matter?

Then I added the extra conditions to the closing of sessions by simply starting the timer if the box is checked:

Code:
 If FormOpt.CheckBoxDelay.Checked Then
            TimerLockout.Start()
            Lockout = True
        End If
On the Timer Tick:

Code:
Private Sub TimerLockout_Tick(sender As Object, e As EventArgs) Handles TimerLockout.Tick
        TimerLockout.Stop() 
        Lockout = False '-Stops the timer if Previous RFID does not return then sets lockout to False
    End Sub
And finally the changes made to the On tag Event:
Code:
    'Tag event handler...we'll display the tag code in the field on the GUI
    Public Sub PhidgetRfidTag(ByVal sender As Object, ByVal e As TagEventArgs) Handles PhidgetRfid.Tag

        MinimumStartThreshhold = CInt(FormOpt.TxtBxMinStart.Text)
        gramData = CInt(ActiveWeight.Text)

        LabelTagLive.Text = e.Tag

        If e.Tag IsNot Nothing And FormOpt.CheckBoxDelay.Checked = False Then
            ValidTag = True
        Else
            ValidTag = False
        End If

        If gramData > MinimumStartThreshhold Then
            ValidWeight = True
        Else
            ValidWeight = False
        End If

        If FormOpt.CheckBoxDelay.Checked = True Then
            LockoutCompare()
            If Lockout = True And TimerLockout.Enabled = True Then
                UpdateTextBoxLockout()  '-Update DataGrid to reflect Lockout
                TimerLockout.Start()    '-Restart the Timer
            Else

            End If
        End If

        If ValidTag And ValidWeight = True Then
            UpdateTextBoxNormal()
            MacroExecute()
        Else
        End If

    End Sub
In a nutshell what I have works halfway... If I enable the checkbox it basically locks out everything haha. The answer has got to be plain enough to allow you all to shame me ...

Anyone got something?
