Question

VB中如何把通配符和变量字符串连接起来

请教大家一下 我编写了如下指令：
Dim back as string , dname as string
Dname = abc
Back = “ * ” & dname & “ *.* ”

我本来希望back被赋值为"*abc*.* " 了，
结果总是显示back的值是“**.*”

这很奇怪啊，难道中间的赋值变量dname一点用都没有？？

我又试了试Back = “ * ” + dname + “ *.* ”
仍然是同样结果

请教大家啊，问题到底在哪里呢！
我新手财富不多，谢谢大家了

Answer 1

Private Sub Form_Load()
Dim back As String, dname As String
dname = "abc"
back = "*" & dname & "*.*"
MsgBox back

End Sub

abc要用双引号括起来，表示他是一个字符串，而不是一个变量。

Answer 2

Dim Back As String, Dname As String
Dname = "abc"
Back = "*" & Dname & "*.*"
