Can't upload to Azure Media Services - File Not Found - azure-media-services

When I run the website locally, the video will upload to azure and I get a publish url. No problem. However, when I publish the website and then try to upload from there, I get this error:
Server Error in '/' Application.

I think you should use this to upload file by uploading the stream
public void UploadFileToAzure(Stream stream, string fileName, string contentType,
EContextType contextType) {
if (stream == null)
throw new ArgumentNullException("stream");
if (fileName == null)
throw new ArgumentNullException("fileName");
CloudBlobContainer blobContainer = null;
switch (contextType)
{
case EContextType.CloudStorage:
blobContainer = AzureBlobUtil.InitializeBlob(Settings.AzureBlobStorageFileStorage, Settings.GetAzureDataConnectionString);
break;
default:
blobContainer = AzureBlobUtil.InitializeBlob(Settings.AzureBlobStorageDocument, Settings.GetAzureDataConnectionString);
break;
}
var blob = blobContainer.GetBlockBlobReference(fileName);
blob.UploadFromStream(stream);
blob.Metadata["FileName"] = fileName;
blob.Metadata["IsArchived"] = false.ToString();
blob.SetMetadata();
// Set the properties
blob.Properties.ContentType = contentType;
blob.SetProperties();
}

MailKit version 2.15.0 disconnection issue

I am using MailKit version 2.15.0. When trying to disconnect the client using DisconnectAsync, I am getting the below error
ClientDisconnect method()==> Exception Message: The ReadAsync method cannot be called when another read operation is pending., Exception String: System.NotSupportedException: The ReadAsync method cannot be called when another read operation is pending.
at System.Net.Security.SslStream.ReadAsyncInternal[TIOAdapter](TIOAdapter adapter, Memory`1 buffer)
at MailKit.Net.Pop3.Pop3Stream.ReadAheadAsync(Boolean doAsync, CancellationToken cancellationToken)
at MailKit.Net.Pop3.Pop3Stream.ReadLineAsync(Stream ostream, Boolean doAsync, CancellationToken cancellationToken)
at MailKit.Net.Pop3.Pop3Engine.ReadLineAsync(Boolean doAsync, CancellationToken cancellationToken)

at MailKit.Net.Pop3.Pop3Client.SendCommandAsync(Boolean doAsync, CancellationToken token, String command)
at MailKit.Net.Pop3.Pop3Client.DisconnectAsync(Boolean quit, Boolean doAsync, CancellationToken cancellationToken)
Below is the code I am using to Disconnect the Client
private async Task DisconnectClient(Hashtable markAsRead, EmailServer emailServer)
{
pollingInProgress = false;
await emailServer.ClientDisconnect(markAsRead);
markAsRead.Clear();
}
internal void MarkAsRead(Hashtable markAsRead)
{
emailBinding.emailSource().MarkRead(markAsRead);
}
internal async Task ClientDisconnect(Hashtable markAsRead)
{
try
{
if (!emailBinding.emailSource().IsConnected)
{
await emailBinding.Connect();
}
FlushClient(markAsRead);
await emailBinding.Disconnect();
}
catch (Exception e)
{
AttachWorkerLogs(string.Format("ClientDisconnect method()==> Exception Message: {0}, Exception String: {1}", e.Message, e.ToString()));
throw;
}
}
private void FlushClient(Hashtable markAsRead)
{
MarkAsRead(markAsRead);
}
Finally calling the disconnect method like this:
public async Task Disconnect()
{
try
{
if (client.IsConnected)
{
await client.DisconnectAsync(true);
}
}
catch (Exception e)
{
AttachLogger(string.Format("Disconnect method()==> Exception Message: {0}, Exception String: {1}", e.Message, e.ToString()));
throw;
}
}
I am unable to figure out what exactly is the issue.
The exception message makes it pretty clear that you are trying to read from the SslStream from multiple threads at the same time.
Since MailKit is not multi-threaded, it means that you are effectively trying to perform 2 or more operations on the same Pop3Client from multiple threads at the same time.
In other words, the problem is not that you are calling Disconnect, the problem is that you are calling Disconnect when your code is also trying to download messages or something from the server.

how to handle 500 error

I'm trying to show custom error message for 404/403/500 error. I'm able to show 404/403 error but unable to show 500 error. Steps I have followed so far -
Step 1: Created a servlet which will set the status as 500
public class ErrorServlet extends SlingSafeMethodsServlet {
#Override
protected void doGet(final SlingHttpServletRequest request,
final SlingHttpServletResponse response) throws ServletException,
IOException {
try{
response.setStatus(500);
} catch (Exception e) {
e.printStackTrace();
}
}
}
Step2: Crated Exception.jsp and Throwable.jsp under apps/sling/servlet/errorhandler
Step3: Added below code in both Exception.jsp and Throwable.jsp
<%#include file="/libs/foundation/global.jsp"%>
<%#taglib prefix="sling" uri="http://sling.apache.org/taglibs/sling/1.0" %><%
%><sling:defineObjects /><%
response.setStatus(500);
request.getRequestDispatcher("/content/myproject/en_US/
errorpages/errorpage500.html").forward(request,response); %>
Now when I hit __http://port:host/path/to/servlet then I get "Internal Server Error" in the browser. It does not send to the expected custom error page which I mentioned.
Kindly let me know what I'm missing here.

crystal report print and export not working

I'm .net developer. now I'm working with crystal report. when I'm printing or exporting crystal report then print dialog open when I press Print, then no print operation occurs. This Print and Export not working at fire fox. only chrome support this functions. Is there extra code required for do this job.
---------------------------updated-----------------------------------------
at class declaration :
public partial class EndUser_FS_File_History : System.Web.UI.Page
{
ReportDocument reportdocument = null;
..........
at load crystal report:
reportdocument = new ReportDocument();
string connectionString = ConfigurationManager.ConnectionStrings["FileSystemConnectionString"].ConnectionString;
SqlConnectionStringBuilder SConn = new SqlConnectionStringBuilder(connectionString);
reportdocument.Load(Server.MapPath(#"~/Admin/UserReport.rpt"));
reportdocument.SetDataSource(myDataSet);
reportdocument.DataSourceConnections[0].SetConnection(SConn.DataSource, SConn.InitialCatalog, SConn.UserID, SConn.Password);
CrystalReportViewer1.ReportSource = reportdocument;
and at Page_Unload event:
protected void Page_Unload(object sender, EventArgs e)
{
if (reportdocument != null)
{
reportdocument.Close();
reportdocument.Dispose();
}
GC.Collect();
}
still problem occurs with large no of records:

There are few steps:
Before Pageload, declare the report as
ReportDocument rpt = null;
protected void Page_Load(object sender, EventArgs e)
{
try
{
rpt= new ReportName; //this is the name of your report
// do all the logic here
}
catch()
{
}
}
protected void Page_Unload(object sender, EventArgs e)
{
if(rpt!=null)
{
rpt.Close();
rpt.Dispose();
}
GC.Collect();
}

Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file

I'm new to JMS and I'm studying the following example
public class SendRecvClient
{
static CountDown done = new CountDown(1);
QueueConnection conn;
QueueSession session;
Queue que;
public static class ExListener
implements MessageListener
{
public void onMessage(Message msg)
{
done.release();
TextMessage tm = (TextMessage) msg;
try {
System.out.println("onMessage, recv text=" + tm.getText());
} catch(Throwable t) {
t.printStackTrace();
}
}
}
public void setupPTP()
throws JMSException,
NamingException
{
InitialContext iniCtx = new InitialContext();
Object tmp = iniCtx.lookup("ConnectionFactory");
QueueConnectionFactory qcf = (QueueConnectionFactory) tmp;
conn = qcf.createQueueConnection();
que = (Queue) iniCtx.lookup("queue/testQueue");
session = conn.createQueueSession(false,
QueueSession.AUTO_ACKNOWLEDGE);
conn.start();
}
public void sendRecvAsync(String text)
throws JMSException,
NamingException
{
System.out.println("Begin sendRecvAsync");
// Setup the PTP connection, session
setupPTP();
// Set the async listener
QueueReceiver recv = session.createReceiver(que);
recv.setMessageListener(new ExListener());
// Send a text msg
QueueSender send = session.createSender(que);
TextMessage tm = session.createTextMessage(text);
send.send(tm);
System.out.println("sendRecvAsync, sent text=" + tm.getText());
send.close();
System.out.println("End sendRecvAsync");
}
public void stop()
