Dim gx As String

Dim fgf() As String = {"'%","%'","'%","%'","'","'","'","'","'","'","'","'","'","'"}

Dim filter As String

For i As Integer = 0 To nms.Length - 1

If Forms("技术部审核").Controls(nms(i)).value IsNot Nothing

If Forms("技术部审核").Controls(nms(i)).Name = "CheckBox1"

gx = ".Checked"

Else

gx = ".value"

End If

If filter > ""

filter = filter & " And "

End If

output.show(gx)

output.show(Forms("技术部审核").Controls(nms(i)) & ".value")

' filter = filter & lms(i) & bjf(i) & fgf(i * 2) & Forms("技术部审核").Controls(nms(i)).value & fgf(i * 2 + 1)

End If

Dim tnm As String = Forms("技术部审核").Name

'Forms("技术部审核").Controls("Table1").Table.filter = filter

老师，代码如上：

output.show(Forms("技术部审核").Controls(nms(i)) & ".value")

这句代码，应该如何正确编写呢？

请老师指点

老师，这样就筛选不了“CheckBox1”的值了

我将您的“msgbox（filter）”，换成ouput.show（filter），执行代码之后：

类别_大类 = '电容'

类别_大类 = '电容' And 类别_小类 = '薄膜电容'

类别_大类 = '电容' And 类别_小类 = '薄膜电容' And 封装_类型 = 'gsdjdh'

类别_大类 = '电容' And 类别_小类 = '薄膜电容' And 封装_类型 = 'gsdjdh' And 封装_引脚 = '4'

如果有效，应该还有一行的

类别_大类 = '电容' And 类别_小类 = '薄膜电容' And 封装_类型 = 'gsdjdh' And 封装_引脚 = '4' And 同意采购 = 'false'

老师，依然是这样的

但是我发现，如果将“checkbox1”勾选，就会有最后一行，不勾选就没有，但是不勾选的时候，就无法对最后一个条件进行筛选，请问老师，有什么方法来解决呢

最后一行

类别_大类 = '电容' And 类别_小类 = '薄膜电容' And 封装_类型 = 'gsdjdh' And 封装_引脚 = '4' And 同意采购 = 'true'

老师，我复制了你的代码，在命令窗口是有效了，仔细看才发现是里面的if条件没有设置过来，

但是将代码复制到窗口执行的时候，就出现如下错误：

.NET Framework 版本：2.0.50727.5485

Foxtable 版本：2015.12.22.1

错误所在事件：窗口,技术部审核,Button1,Click

详细错误信息：

从字符串“”到类型“Boolean”的转换无效。

输入字符串的格式不正确。

老师，现在好了，谢谢你
