FaxComLib FaxJob队列状态总是“待定”

Question

我可以通过COM库库FaxComLib发送传真（添加引用 - > COM选项卡 - > faxcom 1.0类型库）并且传真成功。

我的问题是虽然我可以发送传真，但我似乎无法从传真队列中获得准确的状态。 FaxJob对象的QueueStatus属性始终返回“Pending”。

的环境：Windows 2003 R2企业瓦特/ SP2 - 也尝试在Windows 2008 R2具有相同的结果

这里是我的原型代码：

public void GetFaxStatus(int queueNum) 
    { 
     FaxServer faxServer = new FaxServer(); 
     faxServer.Connect("myfaxservername"); 
     bool isInQueue = false; 

     FaxJobs faxJobs = (FaxJobs)faxServer.GetJobs(); 

     for (int i = 1; i <= faxJobs.Count; i++) 
     { 
      FaxJob j = (FaxJob)faxJobs.Item[i]; 
      MessageBox.Show(faxJobs.Item[i].GetType().ToString() + "\r\n" + CreateStatus(j)); 

      if (j.JobId == queueNum) 
      { 
       MessageBox.Show("Found Job:\r\n" + CreateStatus(j)); 
       isInQueue = true; 
      } 

     } 

     if (isInQueue == false) 
     { 
      MessageBox.Show("Fax is no longer in queue.(...or does not exist)"); 
     } 

     faxServer.Disconnect(); 
    } 

    static string CreateStatus(FaxJob job) 
    { 
     StringBuilder sb = new StringBuilder(); 

     sb.AppendLine(string.Format("Billing Code: {0}", job.BillingCode)); 
     sb.AppendLine(string.Format("Device Status: {0}\r\n", job.DeviceStatus)); 
     sb.AppendLine(string.Format("Queue Status: {0}", job.QueueStatus)); 
     sb.AppendLine(string.Format("Display Name: {0}", job.DisplayName)); 
     sb.AppendLine(string.Format("Fax Number: {0}", job.FaxNumber)); 
     sb.AppendLine(string.Format("Job Id: {0}", job.JobId)); 
     sb.AppendLine(string.Format("Tsid: {0}", job.Tsid)); 
     sb.AppendLine(string.Format("Type: {0}", job.Type)); 
     sb.AppendLine(string.Format("Page Count: {0}", job.PageCount)); 

     return sb.ToString(); 
    } 

当我运行的作业失败（重试超出上限），我得到这个：

这是我曾经获得的任何传真作业的唯一状态;在任何状态下。难道我做错了什么？我配置了传真服务器吗？你能帮我解释一下我的问题吗？

谢谢。 -Jason

所以，我不能拿出任何实质性的东西，但我已经取得了一些进展。如果您在检查状态之前调用FaxJob.Refresh（），您会得到一个更好的结果。看起来大多数时候，你仍然处于无用的状态（在我的情况下是“未知”），但至少它并不总是“待定”。 如果传真失败，这也会返回“Retries Exceeded”状态，但否则，“未知”是唯一可以获得的状态，我想。

下面是一些示例代码：

 if (j.JobId == queueNum) 
     { 
      MessageBox.Show("Found Job:\r\n" + CreateStatus(j)); 
      j.Refresh(); 
      isInQueue = true; 
     }

我认为是最强大的传真状态是使用“Microsoft传真服务扩展COM类型”库，而不是。在添加对COM库的引用后，您可以监听详细了解传真服务器正在发生的事件的状态事件。

我写了一个FaxServerListener类，该类记录了重要的事件，其中一个事件包括一个包含相关状态属性的FaxJobStatus对象。

以下是您要做的注册OnOutgoingJobChanged事件，然后收听。

// ... 
using FAXCOMEXLib; 

public class FaxServerListener 
{ 
    private FaxServer faxServer; 

    public FaxServerListener(string faxServerMachineName) 
    { 
     faxServer = new FaxServer(); 
     faxServer.Connect(faxServerMachineName); 
     RegisterFaxServerEvents(); 
    } 

    private void RegisterFaxServerEvents() 
    { 
     // subscribe to multiple FaxServer events here ... 
     faxServer.OnOutgoingJobChanged += faxServer_OnOutgoingJobChanged; 

     /* very important, you MUST tell the FaxServer object which events you're 
     * listening for, otherwise the events will never raise! 
     * This is what I have set and you should only need one of the event types 
     * to listen for but I didn't research this for your problem 
     */ 
     var events = FAX_SERVER_EVENTS_TYPE_ENUM.fsetACTIVITY | 
        FAX_SERVER_EVENTS_TYPE_ENUM.fsetDEVICE_STATUS | 
        FAX_SERVER_EVENTS_TYPE_ENUM.fsetOUT_ARCHIVE | 
        FAX_SERVER_EVENTS_TYPE_ENUM.fsetOUT_QUEUE; 

     faxServer.ListenToServerEvents(events); 
    } 

    private void faxServer_OnOutgoingJobChanged(FaxServer faxServer, string jobId, 
     FaxJobStatus jobStatus) 
    { 
     // Of course you can do whatever you wish here. This is the method that 
     // subscribes to the event with a JobStatus object 
     string output = string.Format("Outgoing Job Changed -> {0}{1}{2}", 
      jobId, Environment.NewLine, GetJobStatusOutput(jobStatus)); 

     // you could process the FaxJobStatus object how ever you wish here 
     // I raised another event from this listener class with the output data 
     // for other client code to listen to. 
    } 

    private string GetJobStatusOutput(FaxJobStatus jobStatus) 
    { 
     StringBuilder sb = new StringBuilder(); 

     sb.AppendLine("\tDeviceID: " + jobStatus.DeviceId.ToString()); 
     sb.AppendLine("\tCurrent Page: " + jobStatus.CurrentPage.ToString()); 
     sb.AppendLine("\tExt. Status Code: " + jobStatus.ExtendedStatusCode.ToString()); 
     sb.AppendLine("\tExt. Status: " + jobStatus.ExtendedStatus); 
     sb.AppendLine("\tJob Type: " + jobStatus.JobType.ToString()); 
     sb.AppendLine("\tRetries: " + jobStatus.Retries.ToString()); 
     sb.AppendLine("\tSize: " + jobStatus.Size.ToString()); 
     sb.AppendLine("\tStatus: " + jobStatus.Status.ToString()); 
     sb.AppendLine("\tStart: " + jobStatus.TransmissionStart.ToShortTimeString()); 

     if (jobStatus.ExtendedStatusCode != FAX_JOB_EXTENDED_STATUS_ENUM.fjesTRANSMITTING) 
     { 
      sb.AppendLine("\tStop: " + jobStatus.TransmissionEnd.ToShortTimeString()); 
     } 

     sb.AppendLine("\tTSID: " + jobStatus.TSID); 

     return sb.ToString(); 
    } 

} 

这是该代码

Outgoing Job Changed -> 201cce11ee0903f 
    DeviceID: 65538 
    Current Page: 1 
    Ext. Status Code: fjesCALL_COMPLETED 
    Ext. Status: 
    Job Type: fjtSEND 
    Retries: 0 
    Size: 10841 
    Status: fjsINPROGRESS 
    Start: 3:20 PM 
    Stop: 3:21 PM 
    TSID: Fax 

一些输出例如正如你可以看到它仍然显示是你提到的，只有更好的状态设置有ExtendedStatusCode枚举值挂起的传真状态。
