“<>”运算符是什么意思？

Question

以下是我从另一个网站获得的一些代码，但我无法理解<>标志的作用。有人可以解释吗？

Dim FldrPicker As FileDialog 

    Application.ScreenUpdating = False 
    Application.EnableEvents = False 
    Application.Calculation = xlCalculationManual 

    Set FldrPicker = Application.FileDialog(msoFileDialogOpen) 

    With FldrPicker 
     .Title = "Select folder:" 
     .AllowMultiSelect = False 
     If .Show <> -1 Then GoTo NextCode 
     myPath = .SelectedItems(1) & "\" 
    End With 

Answer 1
