数据库设计/打开窗体点击事件在VBA使用访问:具体查询

Question

我希望在"主要信息"表单中编程一个单击事件，该表单将根据在多答案查找字段组合控件(对应于通过独立的单独表相关的数字ID字段/文本字符串类别)中选择的值打开多达17个其他表单。

我学过了这是通用代码:

 Private Sub DiagCat_AfterUpdate()
   Select Case DiagCat
     Case "Cancer [140-208]"
       DoCmd.OpenForm (Cancer_Form)
     Case "Heart Disease [393-398, 402, 410-429]"
       DoCmd.OpenForm (Heart_Disease_Form)
     Case "Stroke [430-438]"
      DoCmd.OpenForm (Stroke_Form)
     Case "Diabetes [250]"
      DoCmd.OpenForm (Diabetes_Form)
     Case "Hypertension [401]"
      DoCmd.OpenForm (Hypertension_Form)
    Case "Liver Disease [070, 571-573]"
      DoCmd.OpenForm (Elevated_Cholesterol_Form)
   End Select
 End Sub

VBA现在发出"Type Mismatch"错误13;在Case "Cancer[140-208]"'行执行错误。

谢谢。

Select Case关键字是根据一个字段的多个值选择操作所需的关键字。

Private Sub cmdOpen_Click() 'where cmdOpen is the button control clicked to open the forms
      Select Case cmbDxCatsID 'assuming cmbDxCatsID is the name of the combobox control on the form
      Case 1
          DoCmd.OpenForm(Form1)
      Case 2
          DoCmd.OpenForm(Form2)
      'etc.........
      End Select
End Sub
