I am having an issue using an external component which can be found here: https://www.codeproject.com/Articles/27738/NET-component-that-simplifies-tracking-of-system

The problem I am having is that I want to talk to the main thread (frmMain), but when this takes place SystemIdleTimer1_OnEnterIdleState wants to create a new form because of SystemIdleTimer1 is a different thread.

Private Sub SystemIdleTimer1_OnEnterIdleState(ByVal sender As System.Object, ByVal e As EdinDazdarevic.IdleEventArgs) Handles SystemIdleTimer1.OnEnterIdleState  
    frmMain.stopActiveTimer()

    MessageBox.Show("Entered idle state")
End Sub

How can I call data in the main thread in the current scenario?

There are some similar questions on StackOverflow, but I am struggling to tie everything together:

Hmm, that is pretty typical Codeproject.com code, it always omits the "only works on my machine" caution. Don't use System.Timers.Timer, use the timer from the toolbox. – Hans Passant Dec 18 '17 at 10:44
After replacing System.Timers with System.Windows.Forms.Timer everything worked as should, thanks! – Vlad Vladimir Hercules Dec 18 '17 at 12:03
