这个意思?
Dim Filter As String
With e.Form.Controls("TextBox1")
    If .Value <> Nothing Then
        If Filter > "" Then
            Filter = Filter & " And "
        End If
        Filter = Filter & "车台产品编号 like '%" & .Value & "%'"
    End If
End With
With e.Form.Controls("TextBox2")
    If .Value <> Nothing Then
        If Filter > "" Then
            Filter = Filter & " And "
        End If
        Filter = Filter & "加工单位 like '%" & .Value & "%'"
    End If
End With
If Filter > "" Then
    Tables("表A").Filter = Filter
End If

字符列才能使用like,整数列要做转换。

Filter = Filter & "convert(车台产品编号,'System.String') like '%" & .Value & "%'"

另外,多个控件条件查询建议使用这种用法:http://www.foxtable.com/webhelp/topics/1058.htm

原因找到了。

Dim Filter As String
Dim txt As String = e.Form.Controls("TextBox1").Text
txt = "'%" & txt & "%'"
If txt > "" Then
    If Filter > "" Then
        Filter = Filter & " And "
    End If
    Filter = "(车台产品编号 like " & txt & "Or 加工单位 Like " & txt & ")"
        msgbox(Filter)
End If

Dim txt2 As String = e.Form.Controls("TextBox2").Text
txt2 = "'%" & txt2 & "%'"   少了这行代码
If txt2 > "" Then
    If Filter > "" Then
        Filter = Filter & " And "
    End If
    Filter = Filter & "(车台产品编号 like " & txt2 & "Or 加工单位 Like " & txt2 & ")"
    msgbox(Filter)


End If

If Filter > "" Then
    Tables("模具清单_Table03").Filter = Filter
End If
