If mousemovecount = 0 Then 'if event does not occur yet then display message Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single) To see click event we have to disable msgbox on mouse move event if it occurred more than once. For example, when you what to click form, you move mouse and mouse move event occurs. Some time, we have to disable message box on an event to be able to see the next event. For example, in Form_Activate() procedure we place message "Form Activate event" in Form_Load() procedure "Form load event" and so on. To see what event occurs, we place Message Box procedure in each event procedure with a message, which tells which event occurs. I initialized all count variables on form load event.
If you write frmMain.BackColor = &H8000000A in the form_initialize event procedure, it will not work, because form is not loaded and backcolor property does not exist yet. If you want to change form appearance (backcolor or text color etc.) then the best way is to place the code performing this change inside the form_activate procedure. If you open any other window and close it, the form will redraw itself and paint event occurs again. Form initialization is the first event that occurs when form is loaded, then form load event occurs, then paint event, then got focus, the last event is activated. It is important to know the sequence of events when form is loaded or unloaded. Purpose of this counting you will understand later. These variables will be used to count each event.
