Q33. If VBA code declares FileCount as a constant rather than a variable, the code tends to run faster. Why is this?

The scope of constants is limited to the procedure that declares them
Constants are declared at compile time, but variables are declared at run time
Once declared in a project, the value of a constant cannot be changed. There is no need to look up the current value of FileCount when it is a constant.
The Const declaraton specifies the most efficient type given the constant's value

an error message
Y and Z
Z = in a message box and then a subsequent error message
Y = in a message box and then a subsequent error message

Q36. The VBA code block shown in the following four options runs when UserForm1's CommandButton1 button is clicked. Which block of code leaves UserForm1 loaded but not visible until the FoundErrors function has checked it, and then enables processing to continue if no errors are found?

:

Private Sub CommandButton1_Click()
If FoundErrors(Me) Then _
Me.Show
End Sub

:

Private Sub CommandButton1_Click()
If Not FoundErrors(UserForm1) Then _
Unload UserForm1
End Sub

:

Private Sub CommandButton1_Click()
Me.Hide
Do While FoundErrors(Me)
Me.Show
Loop
End Sub

:

Private Sub CommandButton1_Click()
Do While FoundErrors(UserForm1)
UserForm1.show
Loop
End Sub

The first requirement is to make UserForm1 loaded but not visible, therefore we need Me.Hide, Me in here referring to UserForm1
