主题：查询按钮的代码 数据表不显示查询结果

请帮忙看看我的代码问题出在哪里？谢谢

故障现象：主表全部数据显示，条件给了后，点击查询按钮 主表不显示查询结果，结果是空的：

查询按钮代码如下：

Dim wllx As WinForm.ComboBox = e.Form.Controls("物料类型")

Dim wlmc As WinForm.ComboBox = e.Form.Controls("物料名称")

Dim wlxh As WinForm.TextBox = e.Form.Controls("物料型号")

Dim wlgg As WinForm.TextBox = e.Form.Controls("物料规格")

Dim ghcj As WinForm.ComboBox = e.Form.Controls("供货厂家")

Tables("物料信息表").Filter="类型= '" & wllx.text & "' And 名称= '" & wlmc.text &"' And 型号 Like '*" & wlxh.text & "*' and 规格 like '* " & wlgg.text & "*' And 厂家='" & ghcj.text &"'"
