【问题描述】:
我有一个简单的 MS Access 表单,它有 3 个对象:一个文本框、一个列表框和一个按钮。表单的预期用途如下:用户在文本框中输入名称,从列表框中选择一个项目,然后单击按钮将数据添加到表中。
但是,当我单击按钮时,我不断收到错误消息,“除非控件具有焦点,否则您无法引用控件的属性或方法。”
下面是我的代码。谢谢!
Private Sub addRecord_button_Click()
Dim CustomerName As String
Dim CustomerType As String
On Error GoTo Errhandler
CustomerName = "[name not selected]"
CustomerType = "[type not selected]"
CustomerName = Customer_TextBox.Text
Select Case Type_ListBox.ListIndex
Case 0
CustomerType = "Type 1"
Case 1
CustomerType = "Type 2"
Case 2
CustomerType = "Type 3"
End Select
'MsgBox ("Name: " & CustomerName & " and Type: " & CustomerType)
DoCmd.RunSQL "INSERT INTO Customer VALUES (CustomerName, CustomerType);"
Errhandler:
MsgBox ("The following error has occured: " & Err & " - " & Error(Err))
End Sub
