how can I return in vba?(in c# we use return)

VB

Private Sub Command54_Click()
If IsNull(CName.Value)
MsgBox ("please fill the blank")
return//how should i return?
Else
MsgBox ("accepted")

I meant to stop the Sub or exit from it! not actually return something

If you would like to return some values, you need to use function, like this:

VB

Sub Test()
    Msgbox "1*2=" &  Twice(1), vbInformation, "Information..."
    Msgbox "5*2=" &  Twice(5), vbInformation, "Information..."
    Msgbox "13*2=" &  Twice(13), vbInformation, "Information..."
End Sub

Function Twice(myVal as Integer) As Integer
    Twice = myVal * 2 
End Function

...but if you would like to return into some instruction inside code block, you need to write some subprogram, like this:

VB

Sub BlaBlaBla()
'some instructions
'...
'subprogram
'here we can return with some conditions 
AnotherOneCheck:
'another instructions
'...
'later...
If some_condition = some_value Then
    GoTo AnotherOneCheck
End If

End Sub

The keyword you need is "Exit Sub" and nothing else. It works like return in a void method; likewise, it is not required (in contrast to functions), as the execution will be returned from Sub after execution of its last statement.
