  • Apache Mina Server Restart java.net.BindException: Address already in use

    - by Kosaki
    Hello, I have a rather annoying problem in my server application. I bind Apache Mina with the following code: acceptor.bind(new InetSocketAddress(PORT)); Where acceptor is an NioSocketAcceptor. Over a HTTP interface I can shutdown the server so I can restart it. Server.ioAcceptor.unbind(new InetSocketAddress(Server.PORT)); for(IoSession session: Server.ioAcceptor.getManagedSessions().values()){ if(session.isConnected() && !session.isClosing()){ session.close(false); } } Server.ioAcceptor.dispose(); Main.transport.stop(); Logger.getRootLogger().warn("System going down. Request from "+context.getRemoteAddress()); System.exit(10); This is the code I use to stop the Mina server. However if I try to start the server again in the next couple of minutes. (Somewhere between 5 minutes and 15 minutes) I get the following exception on start up: java.net.BindException: Address already in use I also tried a simple ioAcceptor.unbind() but there was no difference. The server runs on Centos 5 with OpenJDK. Apache Mina version is 2.0 RC1. Thank you in advance for any ideas on how to resolve this.

  • Encoding issue: Cocoa Error 261?

    - by Attacus
    So I'm fetching a JSON string from a php script in my iPhone app using: NSURL *baseURL = [NSURL URLWithString:@"test.php"]; NSError *encodeError = [[NSError alloc] init]; NSString *jsonString = [NSString stringWithContentsOfURL:baseURL encoding:NSUTF8StringEncoding error:&encodeError]; NSLog(@"Error: %@", [encodeError localizedDescription]); NSLog(@"STRING: %@", jsonString); The JSON string validates when I test the output. Now I'm having an encoding issue. When I fetch a single echo'd line such as: { "testKey":"é" } (I'm aware I could\should be using NSUrlConnection for asynchronous fetching of data, but at this point in the app development, I don't really need it.) The JSON parser works fine and I am able to create a valid JSON object. However, when I fetch my 2MB JSON string, I get presented with: Error: Operation could not be completed. (Cocoa error 261.) and a Null string. My PHP file is UTF8 itself and I am not using utf8_encode() because that seems to double encode the data since I'm already pulling the data as NSUTF8StringEncoding. Either way, in my single-echo test, it's the approach that allowed me to successfully log \ASDAS style UTF8 escapes when building the JSON object. What could be causing the error in the case of the larger string? Also, I'm not sure if it makes a difference, but I'm using the php function addslashes() on my parsed php data to account for quotes and such when building the JSON string.

  • Switching from ListView to VirtualStringTree

    - by Jeff
    Hey S.O! I am trying to build my projects with a VirtualStringTree rather than a Listview, because of the vast speed difference. The thing is, even after looking thru the demo's, I just can't figure out exactly how I would use it as a ListView. Like, adding, deleting, and basically just working with ListView items is so easy, but when I look at the VT, it gets almost too complicated. All I am looking for, is a VT that looks like a ListView, with subitems etc. Here are some routines using the ListView, that I would like to use with VT (This is just a pseudo example: procedure Add; begin with ListView.Items.Add do Begin Caption := EditCaption.Text; SubItems.Add(EditSubItem.Text): End; end; Procedure ReadItem(I : Integer); begin ShowMessage(ListView.Items[I].Caption); ShowMessage(ListView.Items[I].SubItems[0]); end; Of course, also the Delete function, but since thats like 1 line, I didnt bother :P Could anyone maybe translate the above examples into using a ListView style VT? Thanks!

  • Maven Multi-Module builds not honoring failsafe-maven-plugin?

    - by Mike Cornell
    I recently discovered that Hudson was not the problem. In actuality it was Maven itself as the multi-module build was causing the build failure, not Hudson. I just hadn't noticed where the issue actually existed. Leaving the original question here. I'm using the failsafe-maven-plugin to run some integration tests. The difference between failsafe and surefire is that failsafe allows failures and does not fail the build. On my nightly builds there are occasions that a service the integration tests use might be down. In normal builds, the failsafe plugin would let the build continue since the integration tests are allowed to fail. However, Hudson does not seem to respect this and stops the build and produces rain. I tried to turn the failsafe tests off on nightly builds using -DskipITs. This appears to fail since I'm in a multi module build. Any ideas on how to get Maven to respect that these tests can fail even though they're part of a specific module? The project structure is as follows: -parent \-jar \-jar (where integration tests run) \-war \-ear

  • Redirect from URL with QueryString to the same URL without QueryString

    - by Slauma
    I have a page request with a QueryString, say http://www.xyz.net/Orders.aspx?OrderID=1. The page is displayed in a browser. Now there is an asp:LinkButton on the page which should enable the user to open the page without the QueryString (as if he had entered http://www.xyz.net/Orders.aspx directly in the browser's address bar). I had two ideas: 1) Use the PostBackUrl attribute of the LinkButton: <asp:LinkButton ID="LinkButton1" runat="server" Text="Select" PostBackUrl="~/Orders.aspx" /> 2) Use "RedirectUrl" in an event handler: <asp:LinkButton ID="LinkButton1" runat="server" Text="Select" OnClick="LinkButton1_Click" /> ...and... protected void LinkButton1_Click(object sender, EventArgs e) { Response.Redirect("~/Orders.aspx"); } In both cases the browser's address bar shows http://www.xyz.net/Orders.aspx without the QueryString, as I like to have it. But in the first case the page does not change at all. But it should, because I'm evaluating the QueryString in code-behind and control the appearance of the page depending on whether a QueryString exists or not. The second option works as intended. If I am not wrong the second option requires an additional roundtrip: Browser sends request to server Event handler on server side sends Redirect URL to browser Browser sends again request to the server, but with the new URL Server sends new requested page to browser Is this correct at all? Whereas the first option omits the first two steps in the list above, thus saving the additional roundtrip and resulting in: Browser sends request to the server, but with the new URL (the PostbackURL specified in the LinkButton) Server sends new requested page to browser But, as said, the result isn't the same. I'm sure my try to explain the differences between the two options is wrong somewhere. But I don't know where exactly. Can someone explain what's really the difference? Do I really need this second roundtrip of option (2) to achieve what I want? Thanks in advance!

  • Slow query with unexpected index scan

    - by zerkms
    Hello I have this query: SELECT * FROM sample INNER JOIN test ON sample.sample_number = test.sample_number INNER JOIN result ON test.test_number = result.test_number WHERE sampled_date BETWEEN '2010-03-17 09:00' AND '2010-03-17 12:00' the biggest table here is RESULT, contains 11.1M records. The left 2 tables about 1M. this query works slowly (more than 10 minutes) and returns about 800 records. executing plan shows clustered index scan (over it's PRIMARY KEY (result.result_number, which actually doesn't take part in query)) over all 11M records. RESULT.TEST_NUMBER is a clustered primary key. if I change 2010-03-17 09:00 to 2010-03-17 10:00 - i get about 40 records. it executes for 300ms. and plan shows index seek (over result.test_number index) if i replace * in SELECT clause to result.test_number (covered with index) - then all become fast in first case too. this points to hdd IO issues, but doesn't clarifies changing plan. so, any ideas? UPDATE: sampled_date is in table sample and covered by index. other fields from this query: test.sample_number is covered by index and result.test_number too. UPDATE 2: obviously than sql server in any reasons don't want to use index. i did a small experiment: i remove INNER JOIN with result, select all test.test_number and after that do SELECT * FROM RESULT WHERE TEST_NUMBER IN (...) this, of course, works fast. but i cannot get what is the difference and why query optimizer choose such inappropriate way to select data in 1st case.

  • iteration in latex

    - by Tim
    Hi, I would like to use some iteration control flow to simplify the following latex code \begin{sidewaystable} \caption{A glance of images} \centering \begin{tabular}{| c ||c| c| c |c| c|| c |c| c|c|c| } \hline \backslashbox{Theme}{Class} &\multicolumn{5}{|c|}{Class 0} & \multicolumn{5}{|c|}{Class 1} \\ \hline \hline 1 & \includegraphics[scale=2]{../../results/1/0_1.eps} &\includegraphics[scale=2]{../../results/1/0_2.eps} &\includegraphics[scale=2]{../../results/1/0_3.eps} &\includegraphics[scale=2]{../../results/1/0_4.eps} &\includegraphics[scale=2]{../../results/1/0_5.eps} &\includegraphics[scale=2]{../../results/1/1_1.eps} &\includegraphics[scale=2]{../../results/1/1_2.eps} &\includegraphics[scale=2]{../../results/1/1_3.eps} &\includegraphics[scale=2]{../../results/1/1_4.eps} &\includegraphics[scale=2]{../../results/1/1_5.eps} \\ \hline \hline 2 & \includegraphics[scale=2]{../../results/2/0_1.eps} &\includegraphics[scale=2]{../../results/2/0_2.eps} &\includegraphics[scale=2]{../../results/2/0_3.eps} &\includegraphics[scale=2]{../../results/2/0_4.eps} &\includegraphics[scale=2]{../../results/2/0_5.eps} &\includegraphics[scale=2]{../../results/2/1_1.eps} &\includegraphics[scale=2]{../../results/2/1_2.eps} &\includegraphics[scale=2]{../../results/2/1_3.eps} &\includegraphics[scale=2]{../../results/2/1_4.eps} &\includegraphics[scale=2]{../../results/2/1_5.eps} \\ \hline ... % similarly for 3, 4, ..., 22 \hline 23 & \includegraphics[scale=2]{../../results/23/0_1.eps} &\includegraphics[scale=2]{../../results/23/0_2.eps} &\includegraphics[scale=2]{../../results/23/0_3.eps} &\includegraphics[scale=2]{../../results/23/0_4.eps} &\includegraphics[scale=2]{../../results/23/0_5.eps} &\includegraphics[scale=2]{../../results/23/1_1.eps} &\includegraphics[scale=2]{../../results/23/1_2.eps} &\includegraphics[scale=2]{../../results/23/1_3.eps} &\includegraphics[scale=2]{../../results/23/1_4.eps} &\includegraphics[scale=2]{../../results/23/1_5.eps} \\ \hline \end{tabular} \end{sidewaystable} I learn that the forloop package provides the for loop.

How to make the latex code into loops then? Thanks!

  • Eclipse throwing error when copying and pasting

    - by hoffmandirt
    I am using Eclipse 3.5 SR2 for Java EE developers. Each time I press control+C or control+V for the first time after I open a file I get an error. After I close the error, I can successfully copy and paste. The error message made me believe that it was related to the Mylyn plugin, but I uninstalled it and still no difference. Has anyone else experience this problem? I also have the subclipse, adobe flex builder, and maven plugins installed.

  • When to use RDLC over RDL reports?

    - by Daan
    I have been studying SSRS 2005 / 2008 in the past weeks and have created some server side reports. For some application, a colleague suggested that I look into RDLC for that particular situation. I am now trying to get my head around the main difference between RDL and RDLC. Searching for this information yields fragmented information at best. I have learned that: RDLC reports do not store information about how to get data. RDLC reports can be executed directly by the ReportViewer control. But I still don't fully understand the relation between the RDLC file and the other related systems (the Reporting Server, the source database, the client). In order to get a good grasp on RDLC files, I would like to know how their use differs from RDL files and in what situation one would choose RDLC over RDL. Links to resources are also welcome. Update: A thread on the ASP.NET forums discusses this same issue. From it, I have gained some better understanding on the issue. A feature of RDLC is that it can be run completely client-side in the ReportViewer control. This removes the need for a Reporting Services instance, and even removes the need for any database connection whatsoever, but: It adds the requirement that the data that is needed in the report has to be provided manually. Whether this is an advantage or a disadvantage depends on the particular application. In my application, an instance of Reporting Services is available anyway and the required data for the reports can easily be pulled from a database. Is there any reason left for me to consider RDLC, or should I simply stick with RDL?

  • WCF Manual SOAP POST using HttpWebRequest over https with Usertoken

    - by VonBlender
    Hi, I'm writing a client that calls a number of WCF webservices (written externallyt to my company) that are very similar in structure. The design I was hoping to use is to manually build the SOAP message from XML chunks that are stored in a database and then processed through a generic web service handler class. I have access to the WSDL's for each webservice and example working XML. The design approach is such that we can easily add to the message dynamically, hence the reason for not using the auto generated proxy classes I am basically at the last part now with the entire SOAP message constructed but am getting a SOAP fault security error returned. I have used fiddler to compare the message I'm sending with one that is sent using the normal (far simpler...) WCF generated proxy classes and can't see any difference apart from the id attribute of the Usertoken element in the SOAP header. This is where my lack of experience in this area isn't helping. I think this is because the id is generated automatically (presumably because we're using https). My question is how do I generate this programatically? I have searched for hours online but the majority of solutions are either using the proxy classes or not over https. I have briefly looked at WCE but aware this is replaced by WCF now so don't want to waste time looking into this if it's not the solution. Any help with this would be greatly appreciated. I can post some code examples when I'm back in work if it will help but the method I'm using is very straightforward and only using XElements and such like at the moment (as we're using linq to sql). thanks, Andy

  • comparison between string literal

    - by wiso
    This very simple code: #include <iostream> using namespace std; void exec(char* option) { cout << "option is " << option << endl; if (option == "foo") cout << "option foo"; else if (option == "bar") cout << "opzion bar"; else cout << "???"; cout << endl; } int main() { char opt[] = "foo"; exec(opt); return 0; } generate two warning: comparison with string literal results in unspecified behaviour. Can you explain why exactly this code doesn't work, but if I change char opt[] to char *opt it works, but generates the warning? Is it related to the \0 termination? What is the difference between the two declaration of opt? What if I use const qualifier? The solution is to use std::string?

  • WCF NetTcpBinding Security - how does it work?

    - by RemotecUk
    Hi, encountered the following problems trying to work through the quagmire of settings in WCF... I created a WCF client server service using a NetTcp binding. I didn't make any changes to the security settings and when running on one machine it works very nicely. However, when I ran my client from another machine it complained that the server didnt like the security credentials that were sent. I understand now that NetTCP is "secured" by default and that my client would have been passing the wrong security details - namely the windows user name and password (or some form of domain authentication) to my server which as they are not running on the same domain it would not have liked. However, what I don't understand is as follows: I haven't specified any security in my binding - does the standard settings expect a windows user name or password to be sent? I don't have any certificate installed on my server - I understand that NetTCP bindings need some form of public private key to protect the credentials - yet this seemed to work when both client and server were on the same machine - how was the data getting encrypted? Or wants it as WCF knew it was on the same machine and encryption isn't needed? I have had to set my security mode on my client and server to "none" now and they connect nicely. However is there any way to encrypt my data without a certificate? Finally... what is the difference between Transport and Message security? To check my understanding (excuse the scenario!) message security is like if I sent a letter from person A to person B and I encode my hand writing to ensure that if anyone intercepts it they cannot read it? Transport Security is if I decide to have my letter sent by armed transport so that no one can get at it along the way? Is it possible to have any form of encryption in WCF without a certificate? My project is a private project and I dont want to purchase a certificate and the data isnt that sensitive anyway so its just for my own knowledge. Thanks in advance.

  • Codeigniter + TankAuth + Swfupload not able to get the logger user id

    - by Manny Calavera
    Hello. I am using Codeigniter with the TankAuth library installed and trying to upload to index.php/reuqests/doUpload from swfupload but can't access the page as authenticated. I have read many posts around the net about similar problem and tried to set $config['sess_match_useragent'] = FALSE; but still no difference. I have ended up skipping the login check in my controller for testing purposes. But now I need to access tankAuth library from my controller to get the current logged in user ID. It is requested in my application and cannot skip it, I really need to pass the logged in user id to that doUpload model. I have setup controller like this: function doUploadFileFn() { if (!$this->tank_auth->is_logged_in()) { return; } else { $user_id = $this->tank_auth->get_user_id(); $this->load->model('requests/doUploadFile'); $this->doUploadFile->uploadData($user_id); } } Now, it does not pass the is_logged_in() check, as I learned from other posts, CI deletes the session but I have setup the config not to match the user agent but still not working. Is there any solution to this out there ? Thank you.

  • Client WCF DataContract has empty/null values from service

    - by Matt
    I have a simple WCF service that returns the time from the server. I've confirmed that data is being sent by checking with Fiddler. Here's the result object xml that my service sends. <s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"> <s:Body> <GetTimeResponse xmlns="http://tempuri.org/"> <GetTimeResult xmlns:a="http://schemas.datacontract.org/2004/07/TestService.DataObjects" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"> <a:theTime>2010-03-26T09:14:38.066372-06:00</a:theTime> </GetTimeResult> </GetTimeResponse> </s:Body> </s:Envelope> So, as far as I can tell, there's nothing wrong on the server end. It's receiving requests and returning results. But on my silverlight client, all the members of the returned object are either null, blank or a default vaule. As you can see the server returns the current date and time. But in silverlight, theTime property on my object is set to 1/1/0001 12:00 AM (default value). Sooo methinks that the DataContracts do not match up between the server and the silverlight client. Here's the DataContract for the server [DataContract] public class Time { [DataMember] public DateTime theTime { get; set; } } Incredibly simple. And here's the datacontract on my silverlight client. [DataContract] public class Time { [DataMember] public DateTime theTime { get; set; } } Literally the only difference is the namespaces within the application. But still the values being returned are null, empty or a .NET default. Thanks for you help!

  • DataTable.Select Behaves Strangely Using ISNULL Operator on NULL DateTime Column

    - by Paul Williams
    I have a DataTable with a DateTime column, "DateCol", that can be DBNull. The DataTable has one row in it with a NULL value in this column. I am trying to query rows that have either DBNull value in this column or a date that is greater than today's date. Today's date is 5/11/2010. I built a query to select the rows I want, but it did not work as expected. The query was: string query = "ISNULL(DateCol, '" + DateTime.MaxValue + "'") > "' + DateTime.Today "'" This results in the following query: "ISNULL(DateCol, '12/31/9999 11:59:59 PM') > '5/11/2010'" When I run this query, I get no results. It took me a while to figure out why. What follows is my investigation in the Visual Studio immediate window: > dt.Rows.Count 1 > dt.Rows[0]["DateCol"] {} > dt.Rows[0]["DateCol"] == DBNull.Value true > dt.Select("ISNULL(DateCol,'12/31/9999 11:59:59 PM') > '5/11/2010'").Length 0 <-- I expected 1 Trial and error showed a difference in the date checks at the following boundary: > dt.Select("ISNULL(DateCol, '12/31/9999 11:59:59 PM') > '2/1/2000'").Length 0 > dt.Select("ISNULL(DateCol, '12/31/9999 11:59:59 PM') > '1/31/2000'").Length 1 <-- this was the expected answer The query works fine if I wrap the DateTime field in # instead of quotes. > dt.Select("ISNULL(DateCol, #12/31/9999#) > #5/11/2010#").Length 1 My machine's regional settings is currently set to EN-US, and the short date format is M/d/yyyy. Why did the original query return the wrong results? Why would it work fine if the date was compared against 1/31/2000 but not against 2/1/2000?

  • How to add a default value to a custom ASP.NET Profile property

    - by mr.moses
    I know you can add defaultValues using the web.config like this: <profile> <properties> <add name="AreCool" type="System.Boolean" defaultValue="False" /> </properties> </profile> but I have the Profile inherited from a class: <profile inherits="CustomProfile" defaultProvider="CustomProfileProvider" enabled="true"> <providers> <clear /> <add name="CustomProfileProvider" type="CustomProfileProvider" /> </providers> </profile> Heres the class: Public Class CustomProfile Inherits ProfileBase Public Property AreCool() As Boolean Get Return Me.GetPropertyValue("AreCool") End Get Set(ByVal value As Boolean) Me.SetPropertyValue("AreCool", value) End Set End Property End Class I don't know how to set the default value of the property. Its causing errors because without a default value, it uses an empty string, which cannot be converted to a Boolean. I tried adding <DefaultSettingValue("False")> _ but that didn't seem to make a difference. I'm also using a custom ProfileProvider (CustomProfileProvider).

  • VB.Net plugin using Matlab COM Automation Server...Error: 'Could not load Interop.MLApp'

    - by Ben
    My Problem: I am using Matlab COM Automation Server to call and execute matlab .m files from a VB.Net plugin for a CAD program called Rhino 3D. The code works flawlessly when set up as a simple Windows Application in Visual Studio, but when I insert it (and make the requisite reference) into my .Net plugin and test it in the CAD program I get the following error: "Could not load file or assembly 'Interop.MLApp, Version 1.0.0.0, culture=neutral, PublicKeyToken=null' or one of its dependencies. the system cannot find the file specified." What I've Tried: I am baffled as to why this occurs, but I was able to contact the CAD program's technical support staff and they suggested that it has something to do with their DotNet SDK having trouble with references that are located far outside the CAD program directory. They didn't have any solutions so I tried playing around with copylocal and this made no difference. I tried using other COM libraries and the Open Office automation server works fine, although uses url's instead of requiring a reference. I also tested Excel, which does require a reference, and it returned the error: "retrieving the COM class factory for component with CLSID {...} failed due to the following error: 80040154." This may or may not be related to the issue with the Matlab COM reference, but I thought was worthwhile to share. Perhaps is there another way to reference Interop.MLApp? I would appreciate any suggestions or thoughts on how I might make the Matlab Interop.MLApp reference work. Best regards, Ben

  • Time flies like an arrow demo in WinForms

    - by Benjol
    Looking at the Reactive Extensions for javascript demo on Jeff Van Gogh's blog, I thought I'd give it a try in C#/Winforms, but it doesn't seem to work so well. I just threw this into the constructor of a form (with the Rx framework installed and referenced): Observable.Context = SynchronizationContext.Current; var mousemove = Observable.FromEvent<MouseEventArgs>(this, "MouseMove"); var message = "Time flies like an arrow".ToCharArray(); for(int i = 0; i < message.Length; i++) { var l = new Label() { Text = message[i].ToString(), AutoSize = true, TextAlign = ContentAlignment.MiddleCenter }; int closure = i; mousemove .Delay(closure * 150) .Subscribe(e => { l.Left = e.EventArgs.X + closure * 15 + 10; l.Top = e.EventArgs.Y; //Debug.WriteLine(l.Text); }); Controls.Add(l); } When I move the mouse, the letters seem to get moved in a random order, and if I uncomment the Debug line, I see multiple events for the same letter... Any ideas? I've tried Throttle, but it doesn't seem to make any difference. Am I just asking too much of WinForms to move all those labels around? (Cross posted on Rx Forum)

  • CodeIgniter/PHP - Calling a view from within a view

    - by Jack W-H
    Hi Folks Basically for my webapp I'm trying to organise it a bit better. As it at the moment, every time I want to load a page, I have to do it from my controller like so: $this->load->view('subviews/template/headerview'); $this->load->view('subviews/template/menuview'); $this->load->view('The-View-I-Want-To-Load'); $this->load->view('subviews/template/sidebar'); $this->load->view('subviews/template/footerview'); As you can tell it's not really very efficient. So I thought I'd create one 'master' view - It's called template.php. This is the contents of the template view: <?php $view = $data['view']; $this->load->view('subviews/template/headerview'); $this->load->view('subviews/template/menuview'); $this->load->view($view); $this->load->view('subviews/template/sidebar'); $this->load->view('subviews/template/footerview'); ?> And then I thought I'd be able to call it from a controller like this: $data['view'] = 'homecontent'; $this->load->view('template',$data); Unfortunately I simply cannot make this work. Does anyone have any ways around this or fixes I can put into place? I've tried putting ""s and ''s around $view in template.php but that makes no difference. The usual error is "Undefined variable: data" or "Cannot load view: $view.php" etc. Thanks folks! Jack

  • ILOG CPLEX: how to populate IloLPMatrix while using addGe to set up the model?

    - by downer
    I have a queatoin about IloLPMatrix and addGe. I was trying to follow the example of AdMIPex5.java to generate user defined cutting planes based on the solution to the LP relaxation. The difference is that eh initial MIP model is not read in from a mps file, but set up in the code using methods like addGe, addLe etc. I think this is why I ran into problems while copying the exampe to do the following. IloLPMatrix lp = (IloLPMatrix)cplex.LPMatrixIterator().next(); lp from the above line turns to be NULL. I am wondering 1. What is the relationship between IloLPMatrix and the addLe, addGe commands? I tried to addLPMatrix() to the model, and then used model.addGe methods. but the LPMatrix seems to be empty still. How do I populate the IloLPMatrix of the moel according to the value that I had set up using addGe and addLe. Is the a method to this easily, or do I have to set them up row by row myself? I was doing this to get the number of variables and their values by doing lp.getNumVars(). Is there other methods that I can use to get the number of variables and their values wihout doing these, since my system is set up by addLe, addGe etc? Thanks a lot for your help on this.

  • running asp.net 3.5 and asp.net 2.0 in same site

    - by cori
    We're running ASP.Net 2.0 on our corporate web site, and I'd like to get it up to ASP.Net 3.5 as smoothly as possible. The project/solution architecture in VS 2005 is an ASP.Net 2.0 web project and an .Net 2.0 data access layer project which is used by the site code. Upon opening the projects in a new VS 2008 solution they seemed to be converted to .Net 3.5 with a minimum of fuss - they built correctly out of the box, deployed successfully, and seem to work just fine, which is exactly as I would expect given that .Net 2.0 and 3.5 share a common runtime. The major difference after the conversion is that the web.config file's referenced dlls are now the 3.5 versions. What I would like to do is to update the site piecemeal; as I make modifications to a given page send the 3.5 verson of that page over to our webserver and not update the whole site at once. In testing on our dev box this approach seems to be working fine - the site code is interacting with the .Net 3.5 data access layer without difficulty, a handful of pages are running 3.5 page-behind code (by this I mean that they're running assemblies built in VS 2008 - the site is using single-page assemblies for code behind), the 3.5 web.config is in place, and the bulk of the site is running code-behind assemblies built in VS2005. Everything looks great. Which makes me worried that I'm missing something. Is this architecture workable, or is there a problem lying is wait for m that I haven't considered?

  • Hyphen vs Dash : Replace Dash with Hyphen

    - by soldieraman
    Alright so we had a problem recently In reporting services some of the String Columns were appearing as gibberish Chinese characters. On further investigation we found it is the hyphen. Well that's what we though first. On further investigation we found it a dash (or en dash) . Basically the reason this has happened is people copy pasting values into this column from word which converts hyphens into dashes automatically. But if you look at the database they both look the same. Though on the application side you can see the difference. How do I replace the dash with a normal hyphen. If you copy the value in put it in SQL server. A hyphen is gray while a dash is black but they both look exactly the same (i.e not bigger or smaller). Problem is I can't write a REPLACE script then (they are the freakin same) REPLACE ('-' with '-') is there a way special characters like the dash can be identified in SQL server? SQL Server v 2005

  • Kruskal-Wallis test with details on pairwise comparisons

    - by dalloliogm
    The standard stats::kruskal.test module allows to calculate the kruskal-wallis test on a dataset: >>> data(diamonds) >>> kruskal.test.test(price~carat, data=diamonds) Kruskal-Wallis rank sum test data: price by carat by color Kruskal-Wallis chi-squared = 50570.15, df = 272, p-value < 2.2e-16 this is correct, it is giving me a probability that all the groups in the data have the same mean. However, I would like to have the details for each pair comparison, like if diamonds of colors D and E have the same mean price, as some other softwares do (SPSS) when you ask for a Kruskal test. I have found kruskalmc from the package pgirmess which allows me to do what I want to do: > kruskalmc(diamonds$price, diamonds$color) Multiple comparison test after Kruskal-Wallis p.value: 0.05 Comparisons obs.dif critical.dif difference D-E 571.7459 747.4962 FALSE D-F 2237.4309 751.5684 TRUE D-G 2643.1778 726.9854 TRUE D-H 4539.4392 774.4809 TRUE D-I 6002.6286 862.0150 TRUE D-J 8077.2871 1061.7451 TRUE E-F 2809.1767 680.4144 TRUE E-G 3214.9237 653.1587 TRUE E-H 5111.1851 705.6410 TRUE E-I 6574.3744 800.7362 TRUE E-J 8649.0330 1012.6260 TRUE F-G 405.7470 657.8152 FALSE F-H 2302.0083 709.9533 TRUE F-I 3765.1977 804.5390 TRUE F-J 5839.8562 1015.6357 TRUE G-H 1896.2614 683.8760 TRUE G-I 3359.4507 781.6237 TRUE G-J 5434.1093 997.5813 TRUE H-I 1463.1894 825.9834 TRUE H-J 3537.8479 1032.7058 TRUE I-J 2074.6585 1099.8776 TRUE However, this package only allows for one categoric variable (e.g. I can't study the prices clustered by color and by carat, as I can do with kruskal.test), and I don't know anything about the pgirmess package, whether it is maintained or not, or if it is tested. Can you recommend me a package to execute the Kruskal-Wallis test which returns details for every comparison? How would you handle the problem?

  • "Unrecognized configuration section connectionStrings" in app.exe.config

    - by Richard Bysouth
    Hi On a Terminal Server install of my WinForms app, one of my clients gets the following exception on startup: "Unrecognized configuration section connectionStrings" This is occurring in myapp.exe.config but I can't figure out why. Runs perfectly everywhere else, only difference between this install and any other is the connection string. I've searched around, but can only find this issue relating to ASP.NET apps and issues in web.config. Any ideas what could be broken in the config of this WinForms app though? Is it indicating a problem further up in machine.config? FYI the top part of myapp.exe.config is: <?xml version="1.0" encoding="utf-8"?> <configuration> <configSections> <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=jjjjjjjjjj"> <section name="MyApp.Settings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=jjjjjjjj" requirePermission="false" /> </sectionGroup> <sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=jjjjjjjjj"> <section name="MyApp.Settings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=jjjjjjjjjj" allowExeDefinition="MachineToLocalUser" requirePermission="false" /> </sectionGroup> </configSections> <connectionStrings> <add name="MyApp.DataAccessLayer.Settings.MyConnectionString" connectionString="$$$$$$" providerName="System.Data.SqlClient" /> </connectionStrings> ... thanks Richard
