在vb的inputbox中输入一串名字，每个名字之间有逗号，但如何让它输出时去掉逗号，改为空格？

Dim txt As String
txt = InputBox("")
txt = Replace(txt, ",", " ")
MsgBox txt

str.replace(","," ")
str是inputbox中输入的字符串

Private Sub Command1_Click()
Dim aaa As String
Dim bbb As String
aaa = inputbox1.Text
bbb = Replace(aaa, ",", "")
MsgBox (bbb)
End Sub
