' 3. Set properties:
'    • For timer, Interval = 900
'    • For picture box, BackColor = 1 (Blue)
'    • For scroll bar, Max = 900, Min = 100
' 4. Press Alt+F4 to return to the programming environment
' 5. Copy the code example below to the form module
' 6. Press F5 to run the example
 
 SUB HScroll1_Change ()     ' Set interval according to scroll bar value
     Timer1.Interval = 1000 - HScroll1.Value
 END SUB
 
 SUB Timer1_Timer ()        ' Switch BackColor between Red and Blue
     IF Picture1.BackColor = 1 THEN
         Picture1.BackColor = 4
     ELSE
         Picture1.BackColor = 1
     END IF
 END SUB
