' This program illustrates the use of Picture controls, the App.Path property, Beep, 
'   variables with the Date data type, and the use of the system time (Time function).

Option Explicit
Dim mStartTime As Date      ' the system time at the beginning of the game

Private Sub Form_Load()
    mStartTime = Time           ' begin timing the user
    tmrMoving.Interval = 500    ' butterfly moves every 1/2 second
    pctObject.Picture = LoadPicture(App.Path & "\freebutterfly.bmp")
End Sub

Private Sub pctObject_Click()
    Dim FinishTime As Date          ' the system time when user catches butterfly
    Dim UserTime As Date            ' amount of time it takes user to
                                    '   catch butterfly
    
    Beep
    pctObject.Picture = LoadPicture(App.Path & "\capturedbutterfly.bmp")
                                    ' load the picture of captured butterfly
    tmrMoving.Enabled = False       ' stop the butterfly
    
    UserTime = Time - mStartTime    ' calculating time it took user to
                                    '   catch butterfly
                                    
    lblMessage.Caption = "Congratulations, you caught the butterfly in " & Format(UserTime, "h:m:s")
End Sub

Private Sub tmrMoving_Timer()
    pctObject.Left = Int(Rnd * Form1.Width) + 1     ' moving the butterfly at random
