Let the users know that something is being processed in the background as they wait for a long time

Posted By:      Posted Date: September 21, 2010    Points: 0   Category :WPF
 

Hello,

I have a listbox that contains a list of items. The user is required to pick the items from this listbox and add them to another which is called selected items listbox. When doing this he needs to check for any duplicate entries as teh available listbox can contain duplicates but not the selected items list. I have 2 buttons "Add" and "Add All" to add items from available to selected list. The code for Add All button is:

private

Hi,

I wanted to know how to prevent more than one user from uploading the report at a time .I am new to .net ,plss help with the code that would be great.Details are below:

This is a Windos based app written in c# . When User A  clicks Upload option on  one server  from the menu  to upload the files  and at the same time when User B clicks Upload option on different server , User B should be alerted a message saying "User A's uploading is in progress,pls wait" . How to achieve this, plsss help with the code.. I am thinking this logic should be kept in a stored proc, How do I write that proc? plss help

WCF Service: takes very long time to start up

  
Hi, What could be the reasons, why my WCF service takes up to 40 seconds to get started? My service class is set to [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)] I am running a thread inside this class. The WCF service gets initialized and opened within the context of this thread. The Initialization: private void InitializeWCFService() {      // initialize servcie base addrresses      this.SetupBaseAddresses();      //MetaData behaviour : allow HttpGet      ServiceMetadataBehavior metaDataBehavior = new ServiceMetadataBehavior();      metaDataBehavior.HttpGetEnabled = true;      // initialize service host instance      this.seviceHost = new ServiceHost(this, this.httpBaseAddress, this.tcpBaseAddress);      // add service endpoints and behavior.      this.seviceHost.AddServiceEndpoint(typeof(IUpdateServer), this.GetServerBinding(BindingType.Tcp), EndpointName);      this.seviceHost.AddServiceEndpoint(typeof(IUpdateServer), this.GetServerBinding(BindingType.Http), EndpointName);      this.seviceHost.Description.Behaviors.Add(metaDataBehavior);      // MEX endpoint      this.seviceHost.AddServic

SharePoint 2007 + PowerPoint gives "Contacting the server for information" for a long time

  
I've never had this issue for but today all of a sudden I tried to open a PowerPoint document posted to a document library on our SharePoint 2007 site and it gave a message saying "Contacting the server for information" for a long time.  It eventually opened but not until after 5-10 minutes.  Does anyone know what might have caused this?  The file itself is pretty small, only 70KB, and as I said we haven't had this problem before.

Why does it takes such a long time to load a parameter?

  
Hi all,   I have a parameter which is filled with a set of about 90.000 rows. When running the report, it takes a long time to view the report. While it loads the report the CPU on the client is getting up with 50% and the memory stacks 300 MB. I think that I am doing something wrong as when I run the query directly at the cube, it takes just 9 seconds. Does anybody have coped with this problem? If so, what are the best practices in this? Your help will be greatly appreciated! Daniel

Performance of XBAP in .NET 4 degrades after a long idle time.

  

A few of my clients are using XBAP application running over .net 4 client profile in IE8. The operating system they use is windows XP (service pack 2 or 3) on all their machines. We've had no issues during install of the .net framework or our XBAP application but many of them are complaining that after keeping the xbap open for a long time their computer begins to slow down considerably. This specially happens when program is left open without using it for some time. On my own development system which is a windows 7 machine with full .net framework installed i haven't experienced such issue.

I checked for resource usage of the application but there is no significant increase in memory usage. The CPU consumption however becomes quite high, which I suspect is the reason for degradation of performance during these episodes. If this was a single case i would have ignored it for some glitch on their system but this is happening on many machines and I suspect this has got something to do with .net framework on xp machines.

I don't see any reason for why this should be happening. Is there any documented bug, report related to this ? Are there any compatibility issues of .net 4 with other common programs running in xp?  Do you have any idea on why this could be happening ? What kind of data should i provide you s

Delivering Replicated Transaction take very long time

  

Hi All

I have pull transactional replication under SQL 2000 to SQL2005, SQL 2000 as publisher and SQL2005 as Subscriber.

I have setup replication with 28 distribution job agent,i used pull transactional replication. every agent contains 1 or more table to be replicate. i have problem with 1 agent replication with 1 table to be replicated, it call ARAccount_Receivable. since initial snapshot distribution agent show message "Delivering Replicated Transaction". the distribution agent was running for 11days, but the data have lastupdate since 3 days ago, means replication was running but very long time delay. this table size have only 32 million data, if compared to the other table with have size more than 100 milion data was running normal.

Below the agent distribution profile 

-BCPBatchSize : 100000

-CommitBatchSize : 1000

-CommitBatchTreshold : 1000

-HistoryVerboseLevel : 1

-KeepAliveMessageInternal : 300

WCF calling webservice - assigning return value taking a long time

  
0 down vote favorite

I have a wcf service (WCF_A ) which calls another wcf service (WCF_B) (currently I am hosting the WCF_B on my local machine with my credentials – as windows service), WCF_B internally makes a call to a webservice (WS01) that is hosted on the IIS. I have created a test client and call the WCF_A -> WCF_B -> WS01. Just before making the call to (WS01) I start a timer and I stop the timer when the webservice call comes back and the result is assigned to a variable, the flow is as below WCF_B

1)  Debug.WriteLine(“Call to webservice”) 
2)  Starttimer 
3)  Var result = WS01.Function(xxxx) 
4)  Stop

Closing a WCF connection takes a long time when using SSL

  

I have a very puzzling problem closing WCF connections. We utilize several different protocols for different customers. The most common is net.tcp. We now have a customer that requires SSL encryption of their WCF calls. It does seem to work, but exhibits some strange behavior when we close the connection.

Closing the connection takes a long time. This could be caused by any number of problems, but the strange thing is that the more data that was transmitted on the connection, the longer it takes to close. Connections that get a small amount of data close reasonably fast, but if a large amount of data was transmitted, closing the connection can take as long as actually retrieving the data. It almost seems as if the data is being retransmitted back to the server for verification before the connection is closed.

We are using reliable sessions and Binary over HTTP protocol.


Nested Views execution time, how long does it take to "unpack" the SQL?

  

We have the case where in a reporting solution for an application it was decided to build a series of reporting views, fair enough. These views are layered, nested several levels deep at times and, not unexpectedly, as our customer's data grows so these views slow...

To complicate matters further, the report SQL may then join several of these top level reporting views to produce the data it needs.

In a recent support request for a slow performing report we ripped the sql out of the report, pasted it into SSMS and while investigating found a join error in the reports SQL that took execution time from ~ 2 minutes down to about 6 seconds...  Regardless of what we did after that we were unable to reduce the time below 6 seconds using our reporting views. Rewriting the SQL against our base tables takes a fraction of a second to return the needed information.

What I need to do is demonstrate where the extra time in getting the results from the views is spent.  My guess is that it is in untangling all the views and then ending up with a less than optimal query plan. Is there anyway to measure how long it takes the server to "unpack" the nested views into a single SQL statement before it can be executed? Knowing how much of the 6 seconds this is accounting for would be helpful to us in our decision making process.

Thanks,

By any chance can we able to optimize the below query.. It is running for long time..

  

By any chance, can we optimize the below query..This is running for 2 hrs..As of now, i really don't have any execution plans. 

If i replace "IN" with "Exists", i am saving few minutes. Can someone please optimize the query little more?
SELECT pm.pm_no,
pm.pm_key, 
trunc(pm.last_completion_dt), 
pm.location_name,
loc.unid,
loc.location_desc,
loc.tva_eq_owner_key

where 
pm.site_id in ('ALF','BRF', 'COF','CUF','GAF','JOF','JSF','KIF','SHF','WCF', 

SSRS taking a long time to run an MDX query

  

Hi,

I have an MDX query which runs fine in the MDX Sample Application. It runs against an SSAS 2000 cube. In my query there is a recursion kind of a logic. It takes about 1-2 sec to run in the MDX Sample Application. My sample application is in the same server as my AS 2000 cube is. However when I run the same MDX from another server through BIDS (2008) it takes an unusually long amount of time to run. Most of the time it times out. :(

As a workaround I created 4 calculated members in my Cube itself (Initially these were used as members in my MDX). I thought that maybe the recursion logic is the culprit so I modified my MDX, removed the recursion part. But still from my SSRS it is taking a long time.

Any pointers to where I am missing the trick ?

Thanks in advance,

Suman


A time-out occurred while waiting for buffer latch -- type 2 Not continuing to wait.

  

Hi,

when we are executing query in sql server 2005(SP2) we are getting below error.

A time-out occurred while waiting for buffer latch -- type 2, bp 03BD8650, page 1:15883707, stat 0x1c0040d, database id: 7, allocation unit Id: 72057608604745728, task 0x54FA8118 : 5, waittime 300, flags 0x3a, owning task 0x009291F8. Not continuing to wait.

Physical Memory=8G.

Memory Utilization is also looking normal.

please let me know how to avoid this problem and provide me if any article is available.

WPF 4 with SSRS Report Viewer and long running Background Worker Dispatch task.

  

Hello,

I've recently run into an issue with with WPF 4 and the SSRS viewer control with a batch emailing application. See http://www.jenasysdesign.com.au/dnn/Blogs/tabid/71/EntryId/5/WPF-4-SQL-Server-Reporting-Services-processing-application-Memory-Leak.aspx for details of some performance profiling issues I found with this technology stack.

I've got two issues.

Firstly, I implemented a background worker process to handling looping through the 2,800 reports. I found to run the SSRS report viewer to export the report results in a slow memory leak. See Red-gate Ants memory profiler 6 image in the link above. I'm not sure what I need to do to remove weak references with this combination of technology. Any ideas?

Secondly, the following code runs on the background worker process, designed so the user can monitor the progress of the a large batch of report files getting generated.  The catch here is involves using the SSRS viewer to export a reports results requires the Dispatcher.Invoke method to ensure that ReportViewer.xaml screen gets a UI thread, but in the process it interferes with the background workers report progress methods, so the UI doesn't see the progress.  

ASP.NET upgrade seems to be taking a very long time to start

  

At work I'm tryhing to upgrade an ASP.NET 2.0 app (which we wrote using VB.NET 2005) to ASP.NET 4.0.  I had a few problems during the upgrade, but eventually worked them all out.  At the end of the day I decided to give it a quick compile and see if I'd get the start page, so I hit F5 in VS 2010.  I left it that way, and man was it acting weird.  VS 2010 wasn't responding to anything.  If I hovered the mouse over VS 2010's minimize or close buttons, in the upper right corner, then those buttons were flashing very rapidly.  I'm not sure what was going on.  After waiting 15 minutes to see if it would come up, I decided to try clicking on the close button.  Nothing happened.  Eventually, I had to leave (I take public transit, and I have to leave when the bus comes), but I thought I'd leave it going as is, in hopes that it might fix itself.

But what I want to know is this, is this pretty standard behavior?  Does it normally take this long to do this?  This website is of modest size (<100 pages).
