标题：请教一个关于判断字符串中是否含空格的代码。

textchanged 代码如下：

Dim txt As String = e.Form.Controls("TextBox1").Text
Dim tbl As Table = Tables("草绳选产品_Table1")
tbl.Filter= ""
If txt = "" Then
    tbl.Filter = ""
Else
    txt = "'*" & txt.Replace("*","[*]") & "*'"
    '或者 txt = "'*" & strtowide(txt) & "*'"

    tbl.filter = "chanpinname Like " & txt & " Or guige Like " & txt & " "     '如果产品名称包含txt，或规格包含txt
    tbl.Sort = "chanpinname desc,guige desc,danwei desc"
End If

看一下运行效果

无论通过 产品名称筛选 还是 规格筛选，都会得到很多个结果。还是不方便。

我的想法是这样

如果只有一个字符串，那么

tbl.filter = "chanpinname Like " & txt & " or guige Like " & txt & " "     '如果产品名称包含txt，或规格包含txt

如果 字符串中有空格 那么

用空格 分割字符串，前部分=txt2，后部分=txt3

tbl.filter = "chanpinname Like " & txt2 & " and guige Like " & txt3& " "  

1、判断是否空格：

2、将字符串拆分成数组：

奇怪，按以下代码 竟然搜索不到结果

产品表里面有产品名称“特级红双草绳”  规格“4CM” 的记录。

可是录入 "特级红双 4CM" 找不到记录。

Dim txt As String = e.Form.Controls("TextBox1").Text
Dim tbl As Table = Tables("草绳选产品_Table1")
tbl.Filter= ""
If txt = "" Then
    tbl.Filter = ""
Else
    txt = "'*" & txt.Replace("*","[*]") & "*'"
    '或者 txt = "'*" & strtowide(txt) & "*'"

If txt.IndexOf(" ") = -1 Then '如果没有空格
tbl.filter = "chanpinname Like " & txt & " or guige Like " & txt & " "
    tbl.Sort = "chanpinname desc,guige desc,danwei desc"

Else
'Dim txt As String
Dim txt2 As String
Dim txt3 As String
Dim Values() As String
Values = txt.split(" ")
txt2=values(0)
txt3=values(1)

    tbl.filter = "chanpinname Like " & txt2 & " and guige Like " & txt3 & " "
    tbl.Sort = "chanpinname desc,guige desc,danwei desc"
End If
End If

谢谢管理员。元宵节还一直坚守岗位。

代码怎么改呢？

主要是跟这段有关吧

 txt = "'*" & txt.Replace("*","[*]") & "*'"

不知道具体怎么改

好了 非常感谢管理员，顺祝元宵愉快！

Dim txt As String = e.Form.Controls("TextBox1").Text
Dim tbl As Table = Tables("草绳选产品_Table1")
tbl.Filter= ""
If txt = "" Then
    tbl.Filter = ""
Else
    txt = "'*" & txt.Replace("*","[*]") & "*'"
    '或者 txt = "'*" & strtowide(txt) & "*'"

If txt.IndexOf(" ") = -1 Then '如果没有空格
tbl.filter = "chanpinname Like " & txt & " or guige Like " & txt & " "
    tbl.Sort = "chanpinname desc,guige desc,danwei desc"

Else
'Dim txt As String
Dim txt2 As String
Dim txt3 As String
Dim Values() As String
Values = txt.split(" ")
txt2=values(0)& "*'"
txt3="'*"& values(1)

    tbl.filter = "chanpinname Like " & txt2 & " And guige Like " & txt3 & " "
    tbl.Sort = "chanpinname desc,guige desc,danwei desc"
'Messagebox.show(tbl.filter)
End If
End If

我看错了，txt包含单引号了！
