Status 屬性範例 (Field) (VB)
下列範例會使用 Internet Publishing Provider,從讀取/寫入資料夾開啟文件。 Record 中 Field 物件的 Status 屬性會先設為 adFieldPendingInsert,然後更新為 adFieldOk。

Sub Main()
Dim File As ADODB.Record
Dim strFile As String
Dim Cnxn As ADODB.Connection
Dim strCnxn As String
Set Cnxn = New ADODB.Connection
strCnxn = "url=https://MyServer/"
Cnxn.Open strCnxn
Set File = New ADODB.Record
strFile = "Folder/FileName"
' Open a read/write document

File.ActiveConnection = Cnxn
File.Mode = adModeReadWrite
File.Open
Debug.Print "Append a couple of fields"
File.Fields.Append "chektest:fld1", adWChar, 42, adFldUpdatable, "fld1"
File.Fields.Append "chektest:fld2", adWChar, 42, adFldUpdatable, "fld2"
Debug.Print "status for the fields"
Debug.Print File.Fields("chektest:fld1").Status 'adfldpendinginsert
Debug.Print File.Fields("chektest:fld2").Status 'adfldpendinginsert
'turn off error-handling to verify field status
On Error Resume Next
File.Fields.Update
Debug.Print "Update succeeds"
Debug.Print File.Fields("chektest:fld1").Status 'adfldpendinginsert + adFieldUnavailable
Debug.Print File.Fields("chektest:fld2").Status 'adfldpendinginsert + adFieldUnavailable
' resume default error-handling
On Error GoTo 0

File.Close
Cnxn.Close
Set File = Nothing
Set Cnxn = Nothing
End Sub

下列範例會從文件開啟的記錄中刪除已知的欄位。 Status 屬性會先設定為 adFieldOK,然後設為 adFieldPendingUnknown。
Attribute VB_Name = "StatusField"
下列程式碼會從唯讀文件上開啟的記錄刪除欄位。 Status 將會設定為 adFieldPendingDelete。 更新時,刪除將會失敗,而且 Status 將會是 adFieldPendingDelete 加上 adFieldPermissionDenied。 CancelUpdate 會清除擱置的 Status 設定。
Attribute VB_Name = "StatusField"
