我正在尝试在Microsoft Access中创建搜索表格。搜索表将从客户端表中查找值。
我在COMOBOX的OnUpdate
事件中有以下代码,并设置为自动更新Update的表单数据。
Private Sub firstname_combo_Change()
Dim stringSQL As String
Dim RecordSt As Recordset
Dim dBase As Database
Dim strWhere As String
Dim varLname As Variant
Dim varClientID As Database
If Not IsNull(Me.firstname_combo.Column(1)) Then
strWhere = "WHERE [Client_Data].[firstname]='" & Me.firstname_combo.Column(1) & "'"
Me.lastname_cmbo.RowSource = "SELECT [Client_Data].[clientid], [Client_Data].[lastname] FROM Client_Data " & strWhere & ";"
stringSQL = "SELECT TOP 1 [Client_Data].[lastname] FROM Client_Data " & varWhere & " ORDER BY [Client_Data].[lastname];"
Set RecordSt = CurrentDb.OpenRecordset(stringSQL)
RecordSt.MoveFirst
'PLease note there would be multiple rows in the recordset but I need to select only the first row. However, varLname is populated correctly
varClientID = RecordSt.Fields("cleintid").Value
varLname = RecordSt.Fields("lastname").Value
Me.lastname_cmbo.Value = varLname
'MsgBox (varLname)
End If
End Sub
我想在这里做的是:
firstname
的OnChange
,VBA将寻找与firstname
匹配的所有lastnames
,并在lastname
字段中显示为可用选项。将第一行从
RecordSet
拿出来,然后将lastname_combo.value
填充到它。
访问当前正确设置了RowSource
属性,但拒绝填充控件的.Value
属性。因此,我在COMBOBOX中获得了空白的lastname
(带有正确的行扣)。请注意,每个组合都设置为"根据我的组合框中选择的值在我的来自我的记录上找到记录"。
看起来我发现了问题。
我的 RowSource
行就像这样
me.lastname_cmbo.rowsource =" select [client_data]。[clientid],[client_data]。[lastName]来自client_data"&strwhere&strwhere&";"
现在,这意味着访问使用[Client_Data].[clientid]
字段作为ComboBox
中每个元素的值
替换
me.lastname_cmbo.value = varlname用
me.lastname_cmbo.value = varclientid
现在它正常工作。
