我设计的筛选按钮,按照
Dim xm As WinForm.TextBox = e.Form.Controls("姓名")
Dim fz As WinForm.ComboBox = e.Form.Controls("分组")
Dim xyjf As WinForm.TextBox = e.Form.Controls("现有积分")
Dim dw As WinForm.TextBox = e.Form.Controls("工作单位")
Dim yjfx As WinForm.ComboBox = e.Form.Controls("研究方向")
Dim szss As WinForm.TextBox = e.Form.Controls("所在省市")
Dim fzr As WinForm.TextBox = e.Form.Controls("负责人")

Tables("会员信息表").Filter="姓名 like \'*" & xm.Text & "*\' and 分组 like \'*" & fz.Text & "*\' and 现有积分 like \'*" & xyjf.Text & "*\' and 工作单位 like \'*" & dw.Text & "*\' and 研究方向 like \'*" & yjfx.Text & "*\' and 所在省市 like\'*" & szss.Text & "*\' and 负责人 Like \'*" & fzr.Text & "*\'"

点击之后,总是提示"无法将类型为“Foxtable.WinForm.ComboBox”的对象强制转换为类“Foxtable.WinForm.TextBox”。
"应该怎么修改

另外,我想在积分筛选那块,做成大于某一个值的筛选,应该怎么弄啊

我按照http://www.foxtable.com/help/index.html?n=1058.htm的帮助进行修改过,也是有问题,苦恼

你搞错了了类型. 你某个个控件是下拉框,你当作文本框来用了

而且你这样做筛选,某个控件没填写内容,就容易出错

已经修改了文本的问题，现在是
Dim xm As WinForm.TextBox = e.Form.Controls("姓名")
Dim fz As WinForm.ComboBox = e.Form.Controls("分组")
Dim xyjf As WinForm.TextBox = e.Form.Controls("现有积分")
Dim dw As WinForm.TextBox = e.Form.Controls("工作单位")
Dim yjfx As WinForm.ComboBox = e.Form.Controls("研究方向")
Dim szss As WinForm.TextBox = e.Form.Controls("所在省市")
Dim fzr As WinForm.ComboBox = e.Form.Controls("负责人")

Tables("会员信息表").Filter="姓名 like \'*" & xm.Text & "*\' and 分组 like \'*" & fz.Text & "*\' and 现有积分 like \'*" & xyjf.Text & "*\' and 工作单位 like \'*" & dw.Text & "*\' and 研究方向 like \'*" & yjfx.Text & "*\' and 所在省市 like\'*" & szss.Text & "*\' and 负责人 Like \'*" & fzr.Text & "*\'"

现在提示”无法在 System.Int32 和 System.String 上执行“Like”操作。“

现有积分那块，我想实现对某一区间段的筛选，实在不知道对数值是怎么判断的，编程零基础......

谢了，经过反复揣摩，终于修改了比较好的结果，但是还有点问题，对”现有积分”那块的筛选，提示“该字符串未被识别为有效的 DateTime。”，用的textbox啊
代码如下：
Dim Filter As String
With e.Form.Controls("xm")
If .Value IsNot Nothing Then
Filter = "姓名 Like \'*" & .Value & "*\'"
End If
End With
With e.Form.Controls("fz")
If .Value IsNot Nothing Then
If Filter > "" Then
Filter = Filter & " And "
End If
Filter = Filter & "分组 = \'" & .Value & "\'"
End If
End With
With e.Form.Controls("gzdw")
If .Value IsNot Nothing Then
If Filter >"" Then
Filter = Filter & " And "
End If
Filter = Filter & "工作单位 Like \'*" & .Value & "*\'"
End If
End With
With e.Form.Controls("yjfx")
If .Value IsNot Nothing Then
If Filter >"" Then
Filter = Filter & " And "
End If
Filter = Filter & "研究方向 Like \'*" & .Value & "*\'"
End If
End With
With e.Form.Controls("szss")
If .Value IsNot Nothing Then
If Filter >"" Then
Filter = Filter & " And "
End If
Filter = Filter & "所在省市 Like \'*" & .Value & "*\'"
End If
End With
With e.Form.Controls("fzr")
If .Value IsNot Nothing Then
If Filter >"" Then
Filter = Filter & " And "
End If
Filter = Filter & "负责人 Like \'*" & .Value & "*\'"
End If
End With
With e.Form.Controls("xyjf1")
If .Value IsNot Nothing Then
If Filter >"" Then
Filter = Filter & " And "
End If
Filter = Filter & "现有积分 >= #" & .Value & "#"
End If
End With
With e.Form.Controls("xyjf2")
If .Value IsNot Nothing Then
If Filter >"" Then
Filter = Filter & " And "
End If
Filter = Filter & "现有积分 <= #" & .Value & "#"
End If
End With
With e.Form.Controls("hyyxq1")
If .Value IsNot Nothing Then
If Filter >"" Then
Filter = Filter & " And "
End If
Filter = Filter & "会员有效期 >= #" & .Value & "#"
End If
End With
With e.Form.Controls("hyyxq2")
If .Value IsNot Nothing Then
If Filter >"" Then
Filter = Filter & " And "
End If
Filter = Filter & "会员有效期 <= #" & .Value & "#"
End If
End With
With e.Form.Controls("zsyxq1")
If .Value IsNot Nothing Then
If Filter >"" Then
Filter = Filter & " And "
End If
Filter = Filter & "证书有效期 >= #" & .Value & "#"
End If
End With
With e.Form.Controls("zsyxq2")
If .Value IsNot Nothing Then
If Filter >"" Then
Filter = Filter & " And "
End If
Filter = Filter & "证书有效期 <= #" & .Value & "#"
End If
End With
If Filter > "" Then
Tables("会员信息表").Filter = Filter
End If

日期就用日期框. 如果不是日期格式,就不要用#号. 用单引号

太感谢了，终于把筛选的事情弄顺了，对于零基础的新人，而且还被催的很急的情况下，版主帮大忙了
