I have a project using Crystal Reports 2008, whenever I try to print the report, using the print button on the menu I get an error on one of my machines, the Crystal Print Dialog opens, completely empty and then I get a error from windows:
Windows has blocked this software because it can't verify the publisher.
Name: PrintControl.cab
Publisher: Unknown Publisher
This is only happening on my Windows 7 machine. The solution on my Windows XP machine works fine, even if I hit the site under XP from my 7 machine, so I'm assuming something didn't install properly on 7. Any ideas? The 7 machine print dialog comes up blank, just says Print on the title and then the error comes up. The XP machine Print dialog says Print in the title and says Crystal Reports Print Control before the print options come up.
I am unable to connect to my local instance of SQL Server 2008 Express using SQL Server Management Studio.I believe the problem is related to a change I made to the connection protocols. Before the error occurred, I had Shared Memory enabled and Named Pipes and TCP/IP disabled. I then enabled both Named Pipes and TCP/IP, and this is when I started experiencing the problem.
I have now set Named Pipes and TCP/IP back to disabled. When I try to connect to the server with SSMS (with either my SQL server sysadmin login or with windows authentication), I get the following error message:
"A connection was successfully established with the server, but then an error occurred during the login process. (provider: Named Pipes Provider, error: 0 - No process is on the other end of the pipe.) (Microsoft SQL Server, Error: 233)"
My first question here is: why is it returning a Named Pipes error? Why isn't it using Shared Memory? It seems like it is not listening on Shared Memory for some reason?When I set Named Pipes to enabled and try to connect, I get the same error message.My windows account is does not have administrator priviliges on my computer.
I'm currently trying to interface our new intranet (ASP-MVC) with the web front end of our pager system. The pager system's front end is about 10 years old, poor interface and no documentation. To do this I have the form on the intranet post to the server, our server then sends an HTTP POST to the pager server that mimics what its own form sends.
While testing this for overloading (we sent about 10 messages almost concurrently) the pager server crashed, as the system is a black box and the only difference we noticed was the concurrent POSTs the least we can do is try to prevent this happening.I want to have all messages go into a queue that sends at most once every 5-10 seconds but I'm not sure how to implement this,
I didn't specify this earlier but the process should be synchronous from the point of view of the browser, ie webserver gets the http POST request from the browser, message is put into the queue, message is sent from the queue, webserver sends http response to the browser. This is not a high volume service and I expect simultaneous requests to be rare so response will be near instantaneous, it is more of a throttle to prevent potential issues with concurrent requests.
I've got a WCF web service that runs fine at the moment but there is talk about using it very heavily soon. As part of it's normal process it writes a file out, then reads it back in again (don't ask why, I know it's stupid). I'm concerned that if we start hitting it with lots of requests then the following might happen.
1. Request 1 writes the file out.
2. Request 2 comes in and overwrites the file.
3. Request 1 reads the file back in but this is now the wrong file.
My understanding is that the requests would naturally queue up so that request 2 wouldn't start until request 1 had finished, but I'm not totally sure.
I have a music related ASP.NET web site which caches a lot of static information from the database on the first request.Sometimes, the application is reset and cache is cleared while the application is on heavy load and then all http requests go to the database to retrieve that static data and cache it for other requests.
How can I ensure that only one request go to the database and cache the results, so that other request simply read that info from cache and not needlessly retrieve the same info over and over again.Can I use thread locking? For example, can I do something like lock(this) { db access here }?
Currently i'm developing an apllication that sends sms via the asp.net. I'm using msmq for the queuing incase of multiple sending of sms. The wcf will then check for new queue and using teh queue to send out a sms. I've a few question.How do i create a new queue for the msmq via asp.net
View 1 RepliesI have been struggling for days trying to get a simple ActiveX DLL to work with no success despite studying several articles on the subject which I have found online. I suspect I have several things coded incorrectly as I am just not familiar with this and most of the articles on the subject are out of date. I am using Visual Studio 2008 and have been using the Windows SDK V7.1 for digital signing.
What I am trying to do is return the client machineName from the environment class back to the web page (and eventually back to the web server). This is my C# class:
using System;
using System.Reflection;
using System.Runtime.InteropServices; [code]...
Note that I copied my dll to my Windows SDK folder, signed that, copied it back to my cab file which I then copied over to my SDK file, signed the cab file. Then finally, copied the cab file to my website project.
NOTE: See comments at end of first answer. I have purchased a signed certificate from Comodo and with that installed, I now get "Unknown Publisher" error even though the certificate status is "ok", Both the dll and cab file have been signed.I believe my issue now is the control needs to be marked as safe for scripting, http://www.olavaukan.com/2010/08/creating-an-activex-control-in-net-using-c/

View 3 RepliesPRB .NET User controls is considered published by an "Unknown Publisher" from my ASP.NET pages.We have a .NET User conrol, based off the UserControl class and coupled with the IObjectSafety interface that generates a "Unkown Publisher" warning message when our control is deployed from our ASP.NET applications. The warning pops up as a dialog from the browser, asking the user if they want to install our control, saying that it is from an "Unknown Publisher".1) Our <OBJECT> tag is scripted correctly in our page as such:
<object
id=objMyControl
classid="CLSID:########-####-####-####-########"
codebase="MyControl.dll#-1,-1,-1,-1"
style="visibility: hidden; width: 0; height: 0;"

EDIT: ViewState does not change when browser is refreshed, so even if you write to viewstate it will not save the data. i am trying to store a Queue in a viewstate (to track postbacks and refreshes to stop a form from resubmitting). The Queue is only saving with a count of 1 (the first item that is added to it) no matter how many items i add.

private Queue<string> sTemp;
private Queue<string> p_tempQue

//create a Queue of string
//sTemp = new Queue<string>();
this.Load += new EventHandler(this.Page_Load);
this.Init += new EventHandler(this.Page_Init);
}
//In the 'page_Init' event we have created a simple hidden field by name 'hdnGuid' which is attached to the page on the first hit itself.
protected void Page_Init(object sender, EventArgs e)
{
//initializing the hidden field
//create a hidden field with a ID
HiddenField hdnGuid = new HiddenField();
hdnGuid.ID = "hdnGuid";
//if it is the first time the page is loaded, create a new guid and assign it as the hidden field value
if (!Page.IsPostBack)
hdnGuid.Value = Guid.NewGuid().ToString();
//add the hidden field to the page
Page.Form.Controls.Add(hdnGuid);
}
//In the 'page_Load' event we check if the hidden field value is same as the old value. In case the value is not same that means it's a 'postback'
//and if the value is same then its 'refresh'. As per situation we set the 'httpContent.Items["Refresh"]' value.
protected void Page_Load(object sender, EventArgs e)
{
if(p_tempQue != null)
sTemp = p_tempQue;
else
sTemp = new Queue<string>();
//The hdnGuid will be set the first time page is loaded, else the hdnGuid

I have a web application where users can upload the photo. I do have a windows service running which takes the uploaded photo and crops it to different sizes. This runs in a specified interval. Photo will be visible to the user once after it's cropped. So once user uploads the photo and photo cropper has not yet run, they wont be able to see the photo. Due to this behaviour user thinks that there was some error uploading the photo and they will upload it again and again.
where the photocropper runs immediately when the user uploads the photos which is queued.

Would you use java script? Is there a post render event besides page_unload, or could you use page_unload?
Using C# I have
Queue N: 3, 4 9, 11
Queue A: 1, 2, 3, 4, 8, 9, 11, 12, 13
I want to remove all elements from Queue A that are present in Queue N And end up with Queue R: 1, 2, 8, 12, 13. How do I do this in C#. Trying to work with someones API and they offer a way to get the two queues and I need to filter based on one queue returned.
Updated Code Example: I am using a custom data type ModuleDetails
Queue<ModuleDetails> defaultQueue = apiCallDefault();
Queue<ModuleDetails> modQueue = apiCallAllModules();
Currently we are developing an ASMX, ASP 2.0, IIS 7 web service that does some calculations (and return a dynamically generated document) and will take approx. 60 seconds to run.Since whe have a big machine with multiple cores and lots of RAM, I expected that IIS tries its best to route the requests that arrive in its requests queue to all available threads of the app pool's thread pool.But we experience quiet the opposite:When we issue requests to the ASMX web service URL from multiple different clients, the IIS seems to serially process these requests. I.e. request 1 arrives, is being processed, then request 2 is being processed, then request 3, etc
View 2 RepliesNote: I'm avoid flash and silverlight completely. I'm trying to imitate a flash presentation with jQuery.
I have 4 sequences, like the flash used on msn.com's site to show 4 different scenes.
I want these on a timer, but I also wnt to show a small paging control to click to a previous screen.
Would I create a queue for each scene? And when all of the queues finish do I re-create the queues or is there a method to reset?
And what if I want to go to the 2nd scene from the 4th scene by click the pager? Just clear the queue and re-add from that point?
you could have a workflow which is used for the submission and tracking of tickets, with the scenario that when the support desk goes home all of the active workflows generate an e-mail to the person who submitted the ticket saying that their ticket won't be looked at today.What is the best approach to do this?Is it a custom activity or some other method of enumerating all of the active workflows and firing an event/queueing an item to the workflow queue Clearly from the workflow perspective it would be nice to have an activity within it which is fired when,in the case of the example above the office closes.

I have a big problem with my SMTP server for sending emails. It's down often. At this point I am using this code:
MailMessage mailMsg = new MailMessage();
mailMsg.From = new MailAddress("fromMail@example.com");
mailMsg.To.Add("toMail@example.com");
mailMsg.Subject = "...";
mailMsg.IsBodyHtml = true;
mailMsg.BodyEncoding = Encoding.UTF8;
mailMsg.Body = "Mail";
mailMsg.Priority = MailPriority.High;
SmtpClient client = new SmtpClient();
client.Credentials = new NetworkCredential("account@gmail.com", "password");
client.Port = 456;
client.Host = "smtp.gmail.com";
client.EnableSsl = true;
client.Send(mailMsg);
But, when my SMTP server is down I want to put all the emails in a queue and when it recovers I want to send them one a time. Is there any way how to do this programatically in C#?
module thats available for asp.net that uses a queue to send email to an smtp server? the queue being the operative word here.. we need a proper fallback mechanism for storing any messages that can't be sent so that the send can be re-attempted later
