Show a Label while AxAcroPDF is still rendering or loading a file

Question

Something like this

LoadingLabel.Visible = True
Me.AxAcroPDF1.setShowToolbar(False)
Me.AxAcroPDF1.LoadFile(MyFileToLoad)
LoadingLabelVisible = False

is not working, the LoadingLabelVisible = False is executed even when the file still is rendering or loading or with a blank page

I don´t find a property on the AxAcroPDF1, something like "Loaded", "Busy"...

Is there a way to make this work? With a thread by example?
