hrw68529 发表于：2024/4/22 9:07:00在窗口控件事件textchanged中运行下列代码时，出错
代码如下：Dim tian As WinForm.ComboBox = e.Form.Controls("天数")
Dim mss As WinForm.ComboBox = e.Form.Controls("面试室")
Dim wlmc As WinForm.ComboBox = e.Form.Controls("首字母")
If tian.value = Nothing Or mss.value = Nothing Then
Tables("号对人_号对人").Filter= "首字母 like '*" & wlmc.Text & "*'"
ElseIf tian.value IsNot Nothing And mss.value = Nothing Then
Tables("号对人_号对人").Filter="天数 = '" & tian.Text & "'And 面试序号 Is null And 首字母 Like '*" & wlmc.Text & "*'"
ElseIf tian.value IsNot Nothing And mss.value IsNot Nothing Then
Tables("号对人_号对人").Filter="天数 = '" & tian.Text & "' and 面试室 = '" & mss.Text & "'and 面试序号 is null and 首字母 like '*" & wlmc.Text & "*'"
End If

cd_tdh 发表于：2024/4/22 9:15:00参考代码：（如果不是单独查询按钮，代码写到ValueChanged事件）
Dim Filter As String
With e.Form.Controls("天数")
If .Value <> Nothing Then
If Filter > "" Then
Filter = Filter & " And "
End If
Filter &= "天数 = '" & .Value & "'"
End If
End With
With e.Form.Controls("面试室")
If .Value <> Nothing Then
If Filter > "" Then
Filter = Filter & " And "
End If
Filter = Filter & "面试室 like '%" & .Value & "%'"
End If
End With
With e.Form.Controls("首字母")
If .Value <> Nothing Then
If Filter > "" Then
Filter = Filter & " And "
End If
Filter = Filter & "首字母 like '%" & .Value & "%'"
End If
End With
If Filter > "" Then
Tables("号对人_号对人").Filter = Filter
End If

或者
Dim tian As WinForm.ComboBox = e.Form.Controls("天数")
Dim mss As WinForm.ComboBox = e.Form.Controls("面试室")
Dim wlmc As WinForm.ComboBox = e.Form.Controls("首字母")
If tian.Text = "" Or mss.Text = "" Then
Tables("号对人_号对人").Filter = "首字母 like '*" & wlmc.Text & "*'"
ElseIf tian.Text > "" And mss.Text = "" Then
Tables("号对人_号对人").Filter = "天数 = '" & tian.Text & "'And 面试序号 Is null And 首字母 Like '*" & wlmc.Text & "*'"
ElseIf tian.Text > "" And mss.Text > "" Then
Tables("号对人_号对人").Filter = "天数 = '" & tian.Text & "' and 面试室 = '" & mss.Text & "'and 面试序号 is null and 首字母 like '*" & wlmc.Text & "*'"
End If
