請先看這個 : http://hk.geocities.com/jason10312008/Lab3.6.doc
括號內該打甚麼才能造到Lab3.6的效果？

Dim fullName, firstName, lastName As String
Dim n As Integer
fullName = txtName.Text
n = fullName.IndexOf(" ")
firstName = fullName.Substring( )
lastName = fullName.Substring( )

更新1:

With lstResults.Items .Clear() .Add("First name: " & firstName) .Add("Your last name has " & _ lastName.Length & " letters.") 剛才打打不哂，現補充。感激不盡。

✔ 最佳答案

Substring has two overload functions:
Substring(startIndex, length)
Substring(startIndex)

firstName = fullName.Substring(0, n).Trim()
lastName = fullName.Substring(n + 1).Trim()

n is the index of the space, lastName begins at one position after n.
The Trim() function removes any white space at both ends of the string. If the are two spaces between first and last name, the extra space will be removed.
