Question

我有以下代码，它应循环遍历项目中的所有表单，并为每个表单提供一个消息框，其中包含每个表单的设置。我知道循环是正确的，因为我在其他地方使用循环，我只是复制它。为什么消息框是空白的？

   For Each frm In CurrentProject.AllForms
         DoCmd.OpenForm frm.Name, acDesign

        mess = "Form: " & frm.Name & vbCrLf & " Allow Addition: " & CStr(frm.AllowAdditions) & vbCrLf & "Allow Deletions: " & CStr(frm.AllowDeletions) & vbCrLf & "     Allow Edit: " & CStr(frm.AllowEdits)
        MsgBox (mess)
        DoCmd.Close acForm, frm.Name, acSaveYes

  Next frm
  Set frm = Nothing

根据Remou的提示，我得到以下工作：

  For Each frm In CurrentProject.AllForms
     DoCmd.OpenForm frm.Name, acDesign
    Set frm = Forms(frm.Name)
    mess = "Form: " & frm.Name & vbCrLf & " Allow Addition: " & CStr(frm.AllowAdditions) & vbCrLf & "Allow Deletions: " & CStr(frm.AllowDeletions) & vbCrLf & "     Allow Edit: " & CStr(frm.AllowEdits)
    MsgBox (mess)
        DoCmd.Close acForm, frm.Name, acSaveNo

  Next frm
  Set frm = Nothing

如果不打开表单，则无法访问表单属性。您应该只使用Set with objects，而不是字符串。

请参阅Access 2010: Which form control fires a macro?

For Each f In CurrentProject.AllForms
    DoCmd.OpenForm f.Name, acDesign

    Set frm = Forms(f.Name)
    mess = "Form: " & frm.Name & vbCrLf
    mess = mess & " Allow Addition: " & CStr(frm.AllowAdditions) & vbCrLf
    mess = mess & "Allow Deletions: " & CStr(frm.AllowDeletions) & vbCrLf
    mess = mess & "     Allow Edit: " & CStr(frm.AllowEdits)
    MsgBox mess

    DoCmd.Close acForm, f.Name, acSaveNo
Next

如何在消息框中显示表单属性？
