在两个文本框中显示名字和姓氏？

Question

  Dim myName As String
    Dim firstName As String
    Dim lastName As String
    Dim space As Integer
    Dim nameLen As Integer
    myName = txtName.Text
    firstName = txtFirstName.Text
    lastName = txtLastName.Text
    nameLen = Len(myName)
    space = InStr(myName, " ")
    Do Until space > 0
        firstName = Microsoft.VisualBasic.Left(myName, space - 1)
        lastName = Microsoft.VisualBasic.Right(myName, nameLen - space)
    Loop
    txtFirstName.Text = firstName
    txtLastName.Text = lastName

正如我编写的代码，我尝试使用len函数，InStr函数，左右函数来使程序在单独的文本框中显示名字和姓氏。但是，当我输入任何全名时，单击解析名称按钮。名字和姓氏不会出现在两个文本框中。有人可以帮我纠正吗？我将不胜感激！

Dim myName As String
Dim firstName As String
Dim lastName As String
Dim space As Integer
Dim nameLen As Integer
myName = txtName.Text
firstName = txtFirstName.Text
lastName = txtLastName.Text
nameLen = Len(myName)
space = InStr(myName, " ")
firstName = VBA.Strings.Left(myName, space - 1)
lastName = Right(myName, nameLen - space)
txtFirstName.Text = firstName
txtLastName.Text = lastName
