PrintQueue.Refresh 方法
定義
重要
部分資訊涉及發行前產品，在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊，不做任何明確或隱含的瑕疵擔保。
使用電腦上執行之印表機和列印佇列公用程式的值，更新 PrintQueue 的屬性。
public:
override void Refresh();public override void Refresh();override this.Refresh : unit -> unitPublic Overrides Sub Refresh ()部分屬性無法重新整理。
下列範例示範如何使用此方法做為問卷所有印表機的一部分，以取得可能的錯誤狀態。
// Survey queue status for every queue on every print server
System::String^ line;
System::String^ statusReport = "\n\nAny problem states are indicated below:\n\n";
while ((line = fileOfPrintServers->ReadLine()) != nullptr)

System::Printing::PrintQueueCollection^ myPrintQueues = myPS->GetPrintQueues();

if (useAttributesResponse == "y")
{
TroubleSpotter::SpotTroubleUsingQueueAttributes(statusReport, pq);
// TroubleSpotter class is defined in the complete example.
} else
{
TroubleSpotter::SpotTroubleUsingProperties(statusReport, pq);
}
}
}
fileOfPrintServers->Close();
Console::WriteLine(statusReport);
Console::WriteLine("\nPress Return to continue.");
Console::ReadLine();

foreach (PrintQueue pq in myPrintQueues)
{
pq.Refresh();
statusReport = statusReport + "\n\t" + pq.Name + ":";
if (useAttributesResponse == "y")
{
TroubleSpotter.SpotTroubleUsingQueueAttributes(ref statusReport, pq);
// TroubleSpotter class is defined in the complete example.
}
else
{
TroubleSpotter.SpotTroubleUsingProperties(ref statusReport, pq);
}
}// end for each print queue
}// end while list of print servers is not yet exhausted
fileOfPrintServers.Close();
Console.WriteLine(statusReport);
Console.WriteLine("\nPress Return to continue.");
Console.ReadLine();
' Survey queue status for every queue on every print server
Dim line As String
Dim statusReport As String = vbLf & vbLf & "Any problem states are indicated below:" & vbLf & vbLf
line = fileOfPrintServers.ReadLine()
Do While line IsNot Nothing
Dim myPS As New PrintServer(line, PrintSystemDesiredAccess.AdministrateServer)
Dim myPrintQueues As PrintQueueCollection = myPS.GetPrintQueues()
statusReport = statusReport & vbLf & line
For Each pq As PrintQueue In myPrintQueues
pq.Refresh()
statusReport = statusReport & vbLf & vbTab & pq.Name & ":"
If useAttributesResponse = "y" Then
TroubleSpotter.SpotTroubleUsingQueueAttributes(statusReport, pq)
' TroubleSpotter class is defined in the complete example.
Else
TroubleSpotter.SpotTroubleUsingProperties(statusReport, pq)
End If
Next pq ' end for each print queue
line = fileOfPrintServers.ReadLine()
Loop ' end while list of print servers is not yet exhausted
fileOfPrintServers.Close()
Console.WriteLine(statusReport)
Console.WriteLine(vbLf & "Press Return to continue.")
Console.ReadLine()
除非您已經使用 寫入印表機並列印佇列Commit，否則程式對對對象的屬性所做的PrintQueue變更會遺失Refresh。
