  • Jquery Dialog - div disappears after initialization

    - by Zuber
    JQuery Dialog is giving me lots of pain lately. I have the following div which I want to be popped up. (Ignore that the classes do not show the double quotes in the syntax) TABLE class=widget-title-table border=0 cellSpacing=0 cellPadding=0> <TBODY> <TR> <TD class=widget-title><SPAN class=widget-title>Basic Info</SPAN></TD> <TD class=widget-action> <DIV id=edit-actions jQuery1266325647362="3"> <UL class="linkbutton-menu read-mode"> <LI class="control-actions"> <A id="action-button" class="mouse-over-pointer linkbutton">Delete this stakeholder</A> <DIV id="confirmation" class="confirmation-dialog title=Confirmation"> Are you sure you want to delete this stakeholder? </DIV> </LI></UL></DIV></TD></TR></TBODY></TABLE> The JQuery for this is ... $(document).ready(function() { $('#confirmation').dialog({ bgiframe: true, modal: true, autoOpen: false, closeOnEscape: false, draggable: true, position: 'center', resizable: false, width: 400, height: 150 }); }); And the dialog is 'open'ed by var confirmationBox = $('#confirmation',actionContent); if (confirmationBox.length > 0) { //Confirmation Needed $(confirmationBox).dialog('option', 'buttons', { 'No': function() { $(this).dialog('close'); }, 'Yes': function() { $('ul.read-mode').hide(); $.post(requestUrl, {}, ActionCallback(context[0], renderFormUrl), 'json'); $(this).dialog('close'); } }); $(confirmationBox).dialog('open'); } The problem starts in the initialization itself. When the document loads, the <div #confirmation> is deleted from the markup! I had a similar issue earlier, but I cannot use that solution here. On this page I can have multiple PopUp divs. When I added the initialization in just before opening it; the form popped up. But after I close it, the div is removed; so I am not able to see the popup again.

  • migrating an embedded jetty server from v6 to v7

    - by Ceilingfish
    Hi chaps, I have an embedded servlet which I use in unit tests, looks like this: public class UnitTestWebservices extends AbstractHandler { private Server server; private Map<Route,String> data = new HashMap<Route,String>(); public UnitTestWebservices(int port) throws Exception { server = new Server(port); server.setHandler(this); server.start(); } public void handle(String url, HttpServletRequest request, HttpServletResponse response, int arg3) throws IOException, ServletException { final Route route = Route.valueOf(request.getMethod(), url); final String content = data.get(route); if(content != null) { final ServletOutputStream stream = response.getOutputStream(); stream.print(content); stream.flush(); stream.close(); } else { response.sendError(HttpServletResponse.SC_NOT_FOUND); } } .... } That's written using version 6.1.24 of Jetty. I tried switching over to use Jetty 7.1.1.v20100517, and updated that code to this: public class UnitTestWebservices extends AbstractHandler { private Server server; private Map<Route,String> data = new HashMap<Route,String>(); public UnitTestWebservices(int port) throws Exception { server = new Server(port); server.setHandler(this); server.start(); } public void handle(String url, Request request, HttpServletRequest servletRequest, HttpServletResponse response) throws IOException, ServletException { final Route route = Route.valueOf(request.getMethod(), url); final String content = data.get(route); request.setHandled(true); response.setContentType("application/json"); if(content != null) { response.setStatus(HttpServletResponse.SC_OK); final Writer stream = response.getWriter(); stream.append(content); } else { response.sendError(HttpServletResponse.SC_NOT_FOUND); } } } But whenever I tried to access make a request to the server it would hang indefinitely. Has anyone experienced anything similar?. It also printed this into the log: log4j:WARN No appenders could be found for logger (org.eclipse.jetty.util.log). log4j:WARN Please initialize the log4j system properly. org.eclipse.jetty.server.Server@670655dd STOPPED +-UnitTestWebservices@50ef5502 started

  • set radio button in jquery dialog

    - by RememberME
    I have the following if/else on another form and it works perfectly. I've now put it on a form which shows as a jquery dialog. Every alert along the way shows the correct assignment, but when the dialog opens, neither button is selected. $("#create-company").click(function() { alert($('#primary_company').val().length); if ($('#primary_company').val().length > 0) { alert("if secondary"); $('#secondary').attr('checked', 'true'); var id = $("input:radio[name='companyType']:checked").attr('id'); alert(id); } else { alert("else primary"); $('#primary').attr('checked', 'true'); $('#sec').hide(); var id = $("input:radio[name='companyType']:checked").attr('id'); alert(id); } var id = $("input:radio[name='companyType']:checked").attr('id'); alert(id); $('#popupCreateCompany').dialog('open'); }); Dialog: $('#popupCreateCompany').dialog( { autoOpen: false, modal: true, buttons: { 'Add': function() { var dialog = $(this); var form = dialog.find('input:text, select'); $.post('/company/post', $(form).serialize(), function(data) { if (data.Result == "success") { var id = $("input:radio[name='companyType']:checked").attr('id'); if (id == "primary") { $('#company').append($('<option></option>').val(data.company_id).html(data.company_name).attr("selected", true)); $('#primary_company').append($('<option></option>').val(data.company_id).html(data.company_name).attr("selected", true)); $('#company_id').append($('<option></option>').val(data.company_id).html(data.company_name).attr("selected", true)); } else { $('#company_id').append($('<option></option>').val(data.company_id).html(data.company_name)); } dialog.dialog('close'); alert("Company " + data.company_name + " successfully added."); } else { alert(data.Result); }; }, "json") }, 'Cancel': function() { $(this).dialog('close'); } } }); Radio buttons: <label>Company Type:</label> <label for="primary"><input onclick="javascript: $('#sec').hide('slow');$('#primary_company').find('option:first').attr('selected','selected');" type="radio" name="companyType" id="primary" />Primary</label> <label for="secondary"><input onclick="javascript: $('#sec').show('slow');" type="radio" name="companyType" id="secondary" />Subsidiary</label> <div id="sec"> <fieldset> <label for="primary_company">Primary Company:</label> <%= Html.DropDownList("primary_company", Model.SelectPrimaryCompanies, "** Select Primary Company **") %> </fieldset> </div>

  • objective-c default init method for class?

    - by Alex
    Hello, I have two differing methods for initializing my objective-c class. One is the default, and one takes a configuration parameter. Now, I'm pretty green when it comes to objective-c, but I've implemented these methods and I'm wondering if there's a better (more correct/in good style) way to handle initialization than the way I have done it. Meaning, did I write these initialization functions in accordance with standards and good style? It just doesn't feel right to check for the existence of selfPtr and then return based on that. Below are my class header and implementation files. Also, if you spot anything else that is wrong or evil, please let me know. I am a C++/Javascript developer who is learning objective-c as hobby and would appreciate any tips that you could offer. #import <Cocoa/Cocoa.h> // class for raising events and parsing returned directives @interface awesome : NSObject { // silence is golden. Actually properties are golden. Hence this emptiness. } // properties @property (retain) SBJsonParser* parser; @property (retain) NSString* eventDomain; @property (retain) NSString* appid // constructors -(id) init; -(id) initWithAppId:(id) input; // destructor -(void) dealloc; @end #import "awesome.h" #import "JSON.h" @implementation awesome - (id) init { if (self = [super init]) { // if init is called directly, just pass nil to AppId contructor variant id selfPtr = [self initWithAppId:nil]; } if (selfPtr) { return selfPtr; } else { return self; } } - (id) initWithAppId:(id) input { if (self = [super init]) { if (input = nil) { input = [[NSString alloc] initWithString:@"a369x123"]; } [self setAppid:input]; [self setEventDomain:[[NSString alloc] initWithString:@"desktop"]]; } return self; } // property synthesis @synthesize parser; @synthesize appid; @synthesize eventDomain; // destructor - (void) dealloc { self.parser = nil; self.appid = nil; self.eventDomain = nil; [super dealloc]; } @end Thanks!

  • .NET Impersonate and file upload issues

    - by Jagd
    I have a webpage that allows a user to upload a file to a network share. When I run the webpage locally (within VS 2008) and try to upload the file, it works! However, when I deploy the website to the webserver and try to upload the file through the webpage, it doesn't work! The error being returned to me on the webserver says "Access to the path '\05prd1\emp\test.txt' is denied. So, obviously, this is a permissions issue. The network share is configured to allow full access both to me (NT authentication) and to the NETWORK SERVICE (which is .NET's default account and what we have set in our IIS application pool as the default user for this website). I have tried this with and without impersonation upon the webserver and neither way works, yet both ways work on my local machine (in other words, with and without impersonation works on my local machine). The code that does the file upload is below. Please note that the code below includes impersonation, but like I said above, I've tried it with and without impersonation and it's made no difference. if (fuCourses.PostedFile != null && fuCourses.PostedFile.ContentLength > 0) { System.Security.Principal.WindowsImpersonationContext impCtx; impCtx = ((System.Security.Principal.WindowsIdentity)User.Identity).Impersonate(); try { lblMsg.Visible = true; // The courses file to be uploaded HttpPostedFile file = fuCourses.PostedFile; string fName = file.FileName; string uploadPath = "\\\\05prd1\\emp\\"; // Get the file name if (fName.Contains("\\")) { fName = fName.Substring( fName.LastIndexOf("\\") + 1); } // Delete the courses file if it is already on \\05prd1\emp FileInfo fi = new FileInfo(uploadPath + fName); if (fi != null && fi.Exists) { fi.Delete(); } // Open new file stream on \\05prd1\emp and read bytes into it from file upload FileStream fs = File.Create(uploadPath + fName, file.ContentLength); using (Stream stream = file.InputStream) { byte[] b = new byte[4096]; int read; while ((read = stream.Read(b, 0, b.Length)) > 0) { fs.Write(b, 0, read); } } fs.Close(); lblMsg.Text = "File Successfully Uploaded"; lblMsg.ForeColor = System.Drawing.Color.Green; } catch (Exception ex) { lblMsg.Text = ex.Message; lblMsg.ForeColor = System.Drawing.Color.Red; } finally { impCtx.Undo(); } } Any help on this would be very appreciated!

  • How to embed html table into the bpdy of email

    - by Michael Mao
    Hi all: I am sending info to target email via PHP native mail() method right now. Everything else works fine but the table part troubles me the most. See sample output : Dear Michael Mao : Thank you for purchasing flight tickets with us, here is your receipt : Your tickets will be delivered by mail to the following address : Street Address 1 : sdfsdafsadf sdf Street Address 2 : N/A City : Sydney State : nsw Postcode : 2 Country : Australia Credit Card Number : *************1234 Your purchase details are recorded as : <table><tr><th class="delete">del?</th><th class="from_city">from</th><th class="to_city">to</th><th class="quantity">qty</th><th class="price">unit price</th><th class="price">total price</th></tr><tr class="evenrow" id="Sydney-Lima"><td><input name="isDeleting" type="checkbox"></td><td>Sydney</td><td>Lima</td><td>1</td><td>1030.00</td><td>1030</td></tr><tr class="oddrow" id="Sydney-Perth"><td><input name="isDeleting" type="checkbox"></td><td>Sydney</td><td>Perth</td><td>3</td><td>340.00</td><td>1020</td></tr><tr class="totalprice"><td colspan="5">Grand Total Price</td><td id="grandtotal">2050</td></tr></table> The source of table is directly taken from a webpage, exactly as the same. However, Gmail, Hotmail and most of other emails will ignore to render this as a table. So I am wondering, without using Outlook or other email sending agent software, how could I craft a embedded table for the PHP mail() method to send? Current code snippet corresponds to table generation : $purchaseinfo = $_POST["purchaseinfo"]; //if html tags are not to be filtered in the body of email $stringBuilder .= "<table>" .stripslashes($purchaseinfo) ."</table>"; //must send json response back to caller ajax request if(mail($email, 'Your purchase information on www.hardlyworldtravel.com', $emailbody, $headers)) echo json_encode(array("feedback"=>"successful")); else echo json_encode(array("feedback"=>"error")); Any hints and suggestions are welcomed, thanks a lot in advance.

  • Connected host failed to respond (internal NAT address)

    - by MostRandom
    I'm writing my first C# web application that connects to an XML based service. It requires that I present a certificate and feed the XML stream. It seems to authenticate properly but then it gives the following error: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 10.1.10.4:3128 The funny thing is that I'm not on a proxy or anything like that. I'm connecting directly to the internet. At one point I we did use a proxy that with internal NAT address. So my question is: Does Visual Studio have some sort of default proxy setting that I need to change? This IP is no longer used for anything, so I know that I don't need to use any proxy authentication code. using System; using System.Data; using System.Configuration; using System.Collections; using System.Web; using System.Net; using System.Security.Cryptography.X509Certificates; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; namespace WebApplication1 { public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { Uri requestURI = new Uri("*site omitted*"); //Create the Request Object HttpWebRequest pageRequest = (HttpWebRequest)WebRequest.Create(requestURI); //After installing the cert on the server export a client cert to the working directory as Deluxe.cer string certFile = "*certificate omitted*"; X509Certificate cert = X509Certificate.CreateFromCertFile(certFile); //Pull in your Data, if it is from an external xml as below or create an xml string with variables if a dynamic post is required. string xmlPath = "*XML omitted*"; System.Xml.XmlDocument passXML = new System.Xml.XmlDocument(); passXML.Load(xmlPath); //XML String with the data needed to pass string postData = passXML.OuterXml; //Set the Request Object parameters pageRequest.ContentType = "application/x-www-form-urlencoded"; pageRequest.Method = "POST"; pageRequest.AllowWriteStreamBuffering = false; pageRequest.AllowAutoRedirect = false; pageRequest.ClientCertificates.Add(cert); postData = "xml_data=" + Server.UrlEncode(postData); pageRequest.ContentLength = postData.Length; //Create the Post Stream Object System.IO.StreamWriter postStream = new System.IO.StreamWriter(pageRequest.GetRequestStream()); //Write the data to the post stream postStream.Write(postData); postStream.Flush(); postStream.Close(); //Set the Response Object HttpWebResponse postResponse = (HttpWebResponse)pageRequest.GetResponse();

  • CDI SessionScoped Bean instance remains unchanged when login with different user

    - by Jason Yang
    I've been looking for the workaround of this problem for rather plenty of time and no result, so I ask question here. Simply speaking, I'm using a CDI SessionScoped Bean User in my project to manage user information and display them on jsf pages. Also container-managed j_security_check is used to resolve authentication issue. Everything is fine if first logout with session.invalidate() and then login in the same browser tab with a different user. But when I tried to directly login (through login.jsf) with a new user without logout beforehand, I found the user information remaining unchanged. I debugged and found the User bean, as well as the HttpSession instance, always remaining the same if login with different users in the same browser, as long as session.invalidate() not invoked. But oddly, the session id did modified, and I've both checked in Java code and Firebug. org.apache.catalina.session.StandardSessionFacade@5d7b4092 StandardSession[c69a71d19f369d08b5dddbea2ef0] attrName = org.jboss.weld.context.conversation.ConversationIdGenerator : attrValue=org.jboss.weld.context.conversation.ConversationIdGenerator@583c9dd8 attrName = org.jboss.weld.context.ConversationContext.conversations : attrValue = {} attrName = org.jboss.weld.context.http.HttpSessionContext#org.jboss.weld.bean-Discipline-ManagedBean-class com.netease.qa.discipline.profile.User : attrValue = Bean: Managed Bean [class com.netease.qa.discipline.profile.User] with qualifiers [@Any @Default @Named]; Instance: com.netease.qa.discipline.profile.User@c497c7c; CreationalContext: org.jboss.weld.context.CreationalContextImpl@739efd29 attrName = javax.faces.request.charset : attrValue = UTF-8 org.apache.catalina.session.StandardSessionFacade@5d7b4092 StandardSession[c6ab4b0c51ee0a649ef696faef75] attrName = org.jboss.weld.context.conversation.ConversationIdGenerator : attrValue = org.jboss.weld.context.conversation.ConversationIdGenerator@583c9dd8 attrName = com.sun.faces.renderkit.ServerSideStateHelper.LogicalViewMap : attrValue = {-4968076393130137442={-7694826198761889564=[Ljava.lang.Object;@43ff5d6c}} attrName = org.jboss.weld.context.ConversationContext.conversations : attrValue = {} attrName = org.jboss.weld.context.http.HttpSessionContext#org.jboss.weld.bean-Discipline-ManagedBean-class com.netease.qa.discipline.profile.User : attrValue = Bean: Managed Bean [class com.netease.qa.discipline.profile.User] with qualifiers [@Any @Default @Named]; Instance: com.netease.qa.discipline.profile.User@c497c7c; CreationalContext: org.jboss.weld.context.CreationalContextImpl@739efd29 attrName = javax.faces.request.charset : attrValue = UTF-8 Above block contains two successive logins and their Session info. We can see that the instance(1st row) the same while session id(2nd row) different. Seems that session object is reused to contain different session id and CDI framework manages session bean life cycle in accordance with the session object only(?). I'm wondering whether there could be only one server-side session object within the same browser unless invalidated? Since I'm adopting j_security_check I fancy intercepting it and invalidating old session is not so easy. So is it possible to accomplish the goal without altering the CDI+JSF+j_security_check design that one can relogin with different account in the same or different tab within the same browser? Really look forward for your response. More info: Glassfish v3.1 is my appserver.

  • Using VCL for the web (intraweb) as a trick for adding web interface to a legacy non-tiered (2 tiers

    - by user193655
    My team is maintaining a huge Client Server win32 Delphi application. It is a client/server application (Thick client) that uses DevArt (SDAC) components to connect to SQL Server. The business logic is often "trapped" in Component's event handlers, anyway with some degree of refactoring it is doable to move the business logic in common units (a big part of this work has already been done during refactoring... Maintaing legacy applications someone else wrote is very frustrating, but this is a very common job). Now there is the request of a web interface, I have several options of course, in this question i want to focus on the VCL for the web (intraweb) option. The idea is to use the common code (the same pas files) for both the client/server application and the web application. I heard of many people that moved legacy apps from delphi to intraweb, but here I am trying to keep the Thick client too. The idea is to use common code, may be with some compiler directives to write specific code: {$IFDEF CLIENTSERVER} {here goes the thick client specific code} {$ELSE} {here goes the Intraweb specific code} {$ENDIF} Then another problem is the "migration plan", let's say I have 300 features and on the first release I will have only 50 of them available in the web application. How to keep track of it? I was thinking of (ab)using Delphi interfaces to handle this. For example for the User Authentication I could move all the related code in a procedure and declare an interface like: type IUserAuthentication= interface['{0D57624C-CDDE-458B-A36C-436AE465B477}'] procedure UserAuthentication; end; In this way as I implement the IUserAuthentication interface in both the applications (Thick Client and Intraweb) I know that That feature has been "ported" to the web. Anyway I don't know if this approach makes sense. I made a prototype to simulate the whole process. It works for a "Hello world" application, but I wonder if it makes sense on a large application or this Interface idea is only counter-productive and can backfire. My question is: does this approach make sense? (the Interface idea is just an extra idea, it is not so important as the common code part described above) Is it a viable option? I understand it depends a lot of the kind of application, anyway to be generic my one is in the CRM/Accounting domain, and the number of concurrent users on a single installation is typically less than 20 with peaks of 50. EXTRA COMMENT (UPDATE): I ask this question because since I don't have a n-tier application I see Intraweb as the unique option for having a web application that has common code with the thick client. Developing webservices from the Delphi code makes no sense in my specific case, so the alternative I have is to write the web interface using ASP.NET (duplicating the business logic), but in this case I cannot take advantage of the common code in an easy way. Yes I could use dlls maybe, but my code is not suitable for that.

  • WCF doesn't find client configuration

    - by ultraman69
    Hi ! I have a WCF service on server B. Then on the machine A is the client, which is a Windows service. In a separate dll stands all the business logic for this service. So my proxy for the WCF is on that side. I have 2 app.config (client side only) : 1 for the service and another one in the dll. So I tried (for test purpose) puting the servicemodel config section in both. Both still, it doesn't work, it says that it can't find the endpoint with that name and for that contract... What I'm trying to do here is modify the configuration programatically. Here' the code in the business layer dll : Dim ep As New EndpointAddress(New Uri(ConfigurationManager.AppSettings(nomServeurCible)), _ EndpointIdentity.CreateDnsIdentity(ConfigurationManager.AppSettings("Identity_" & nomServeurCible))) serviceCible = New ServiceProxy.ExecOperClient("wsHttp", ep) And here is a sample of the config file : <add key="TEST1" value="http://TEST1:8000/MySpacePerso/ExecOperService"/> <add key="TEST1_CertificateSerialNumber" value="10 hj 6y 7b 00 01 32 12 01 21"/> <add key="Identity_TEST1" value="TEST1"/> <system.serviceModel> <client> <endpoint address="http://SERV_NAME:8000/CSSTQDA/ExecOperService" binding="wsHttpBinding" behaviorConfiguration="myClientBehavior" bindingConfiguration="MybindingCon" contract="ExecOper.Service.IExecOper" name="wsHttp"> <identity> <dns value="SERV_CERT_NAME"/> </identity> </endpoint> </client> <bindings> <wsHttpBinding> <binding name="MybindingCon"> <security mode="Message"> <message clientCredentialType="UserName" /> </security> </binding> </wsHttpBinding> </bindings> <behaviors> <serviceBehaviors> <behavior name="ServiceTraitementBehavior"> <serviceMetadata httpGetEnabled="True"/> <serviceDebug includeExceptionDetailInFaults="True" /> </behavior> </serviceBehaviors> <endpointBehaviors> <behavior name="myClientBehavior"> <clientCredentials> <serviceCertificate> <authentication certificateValidationMode="ChainTrust" revocationMode="NoCheck"/> </serviceCertificate> </clientCredentials> </behavior> </endpointBehaviors> </behaviors>

  • How to update strongly typed Html.DropDownList using Jquery

    - by Remnant
    I have a webpage with two radiobuttons and a dropdownlist as follows: <div class="sectionheader">Course <div class="dropdown"><%=Html.DropDownList("CourseSelection", Model.CourseList, new { @class = "dropdown" })%> </div> <div class="radiobuttons"><label><%=Html.RadioButton("CourseType", "Advanced", false )%> Advanced </label></div> <div class="radiobuttons"><label><%=Html.RadioButton("CourseType", "Beginner", true )%> Beginner </label></div> </div> The dropdownlist is strongly typed and populated with Model.CourseList (NB - on the first page load, 'Beginner' is the default selection and the dropdown shows the beginner course options accordingly) What I want to be able to do is to update the DropDownList based on which radiobutton is selected i.e. if 'Advanced' selected then show one list of course options in dropdown, and if 'Beginner' selected then show another list of courses. The code I would like to call sits within my Controller: public JsonResult UpdateDropDown(string courseType) { IDropDownList dropdownlistRepository = new DropDownListRepository(); IEnumerable<SelectListItem> courseList = dropdownlistRepository.GetCourseList(courseType); return Json(courseList); } Edit - Updated below to show latest position Using examples provided in jQuery in Action, I now have the following jQuery code: $('.radiobuttons input:radio').click(function() { var courseType = $(this).val(); //Get selected courseType from radiobutton var dropdownList = $(".dropdown"); //Ref for dropdownlist $.getJSON("/ByCourse/UpdateDropDown", { courseType: courseType }, function(data) { $(dropdownList).loadSelect(data); }); }); The loadSelect function is taken straight from the book and is as follows: (function($) { $.fn.emptySelect = function() { return this.each(function() { if (this.tagName == 'SELECT') this.options.length = 0; }); } $.fn.loadSelect = function(optionsDataArray) { return this.emptySelect().each(function() { if (this.tagName == 'SELECT') { var selectElement = this; $.each(optionsDataArray, function(index, optionData) { var option = new Option(optionData.Text, optionData.Value); if ($.browser.msie) { selectElement.add(option); } else { selectElement.add(option, null); } }); } }); } })(jQuery); 1 day+ later I still cannot get this to work. Assuming the jQuery code is correct then I can only think that the issue is with retrieving the actual data with $getJSON. I have verified that JsonResult UpdateDropDown does actually retrieve valid data. What am I missing? Assembly reference? (NB: I have MicrosoftAjax.js and MicrosoftMvcAjax.js in my head tags of the master page Should JsonResult be ActionResult? (I have seen both used in samples on web) Do I need to register route Controller/UpdateDropDown in Global.asax? Any further guidance would be appreciated.

  • .NET C# Filestream writing to file and reading the bfile

    - by pythonrg7
    I have a web service that checks a dictionary to see if a file exists and then if it does exist it reads the file, otherwise it saves to the file. This is from a web app. I wonder what is the best way to do this because I occasionally get a FileNotFoundException exception if the same file is accessed at the same time. Here's the relevant parts of the code: String signature; signature = "FILE," + value1 + "," + value2 + "," + value3 + "," + value4; // this is going to be the filename string result; MultipleRecordset mrSummary = new MultipleRecordset(); // MultipleRecordset is an object that retrieves data from a sql server database if (mrSummary.existsFile(signature)) { result = mrSummary.retrieveFile(signature); } else { result = mrSummary.getMultipleRecordsets(System.Configuration.ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString.ToString(), value1, value2, value3, value4); mrSummary.saveFile(signature, result); } Here's the code to see if the file already exists: private static Dictionary dict = new Dictionary(); public bool existsFile(string signature) { if (dict.ContainsKey(signature)) { return true; } else { return false; } } Here's what I use to retrieve if it already exists: try { byte[] buffer; FileStream fileStream = new FileStream(@System.Configuration.ConfigurationManager.AppSettings["CACHEPATH"] + filename, FileMode.Open, FileAccess.Read, FileShare.Read); try { int length = 0x8000; // get file length buffer = new byte[length]; // create buffer int count; // actual number of bytes read JSONstring = ""; while ((count = fileStream.Read(buffer, 0, length)) > 0) { JSONstring += System.Text.ASCIIEncoding.ASCII.GetString(buffer, 0, count); } } finally { fileStream.Close(); } } catch (Exception e) { JSONstring = "{\"error\":\"" + e.ToString() + "\"}"; } If the file doesn't previously exist it saves the JSON to the file: try { if (dict.ContainsKey(filename) == false) { dict.Add(filename, true); } else { this.retrieveFile(filename, ipaddress); } } catch { } try { TextWriter tw = new StreamWriter(@System.Configuration.ConfigurationManager.AppSettings["CACHEPATH"] + filename); tw.WriteLine(JSONstring); tw.Close(); } catch { } Here are the details to the exception I sometimes get from running the above code: System.IO.FileNotFoundException: Could not find file 'E:\inetpub\wwwroot\cache\FILE,36,36.25,14.5,14.75'.

  • CSS rules not getting applied in JSPs ?

    - by lakshmanan
    Im building a web application using struts2. I have an authentication interceptor at the top of all the interceptors (I have set it up as such) which checks whether a user is logged in. If not, it will give a login page as result. In login page, I have some set of standard CSS rules which I use for all the JSPs in the app. But that login page coming via that interceptor is not getting applied with CSS rules. Don't know why. Here is my JSP login page. <%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <%@ taglib prefix="s" uri="/struts-tags" %> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <link rel="stylesheet" href="styles/styles.css" type="text/css" /> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <title>Projit Login </title> </head> <body> <div id="header"> <h1>Projit</h1> </div> <div id="col1"> <s:form action="/login.action"> <s:textfield name="some field" label="Enter somefield" /> <s:textfield name="username" label="Username" /> <s:password name="password" label="Password" /> <s:submit value="Sign In" /> </s:form> </div> <div id="col2"> <h3>Login</h3> </div> <div id="footer"> some footer </div> </body> </html> the css file is present in WebContent/styles/styles.css I am using eclipse for development. this problem of CSS rules not getting applied occurs at times for other jsps as well inspite of the CSS file being present in the correct location. I guess there must be some URL thing behind this problem. I have tried hard but it is not working till now. Please help.

  • Reporting Services as PDF through WebRequest in C# 3.5 "Not Supported File Type"

    - by Heath Allison
    I've inherited a legacy application that is supposed to grab an on the fly pdf from a reporting services server. Everything works fine up until the point where you try to open the pdf being returned and adobe acrobat tells you: Adobe Reader could not open 'thisStoopidReport'.pdf' because it is either not a supported file type or because the file has been damaged(for example, it was sent as an email attachment and wasn't correctly decoded). I've done some initial troubleshooting on this. If I replace the url in the WebRequest.Create() call with a valid pdf file on my local machine ie: @"C:temp/validpdf.pdf") then I get a valid PDF. The report itself seems to work fine. If I manually type the URL to the reporting services report that should generate the pdf file I am prompted for user authentication. But after supplying it I get a valid pdf file. I've replace the actual url,username,userpass and domain strings in the code below with bogus values for obvious reasons. WebRequest request = WebRequest.Create(@"http://x.x.x.x/reportServer?/reports/reportNam&rs:format=pdf&rs:command=render&rc:parameters=blahblahblah"); int totalSize = 0; request.Credentials = new NetworkCredential("validUser", "validPass", "validDomain"); request.Timeout = 360000; // 6 minutes in milliseconds. request.Method = WebRequestMethods.Http.Post; request.ContentLength = 0; WebResponse response = request.GetResponse(); Response.Clear(); BinaryReader reader = new BinaryReader(response.GetResponseStream()); Byte[] buffer = new byte[2048]; int count = reader.Read(buffer, 0, 2048); while (count > 0) { totalSize += count; Response.OutputStream.Write(buffer, 0, count); count = reader.Read(buffer, 0, 2048); } Response.ContentType = "application/pdf"; Response.Cache.SetCacheability(HttpCacheability.Private); Response.CacheControl = "private"; Response.Expires = 30; Response.AddHeader("Content-Disposition", "attachment; filename=thisStoopidReport.pdf"); Response.AddHeader("Content-Length", totalSize.ToString()); reader.Close(); Response.Flush(); Response.End();

  • Apple Push Notifications With Foreign Accent Characters Not Receiving

    - by confeng
    I'm sending push notifications and when the message contains foreign characters (Turkish in my case) like I, s, ç, g... The message does not arrive to devices. Here's my code: $message = 'THIS is push'; $passphrase = 'mypass'; $ctx = stream_context_create(); stream_context_set_option($ctx, 'ssl', 'local_cert', 'MyPemFile.pem'); stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase); // Open a connection to the APNS server $fp = stream_socket_client( 'ssl://gateway.push.apple.com:2195', $err, $errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx); if (!$fp) exit("Failed to connect: $err $errstr" . PHP_EOL); echo 'Connected to Apple service. ' . PHP_EOL; // Encode the payload as JSON $body['aps'] = array( 'alert' => $message, 'sound' => 'default' ); $payload = json_encode($body); $result = 'Start'.PHP_EOL; $tokenArray = array('mytoken'); foreach ($tokenArray as $item) { // Build the binary notification $msg = chr(0) . pack('n', 32) . pack('H*', $item) . pack('n', strlen($payload)) . $payload; // Send it to the server $result = fwrite($fp, $msg, strlen($msg)); if (!$result) echo 'Failed message'.PHP_EOL; else echo 'Successful message'.PHP_EOL; } // Close the connection to the server fclose($fp); I have tried encoding $message variable with utf8_encode() but the message received as "THÝS is push". And other ways like iconv() didn't work for me, some of them cropped Turkish characters, some didn't receive at all. I also have header('content-type: text/html; charset: utf-8'); and <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> in my page. I don't think the problem appears while I set the value but maybe with pack() function. Any ideas to solve this without replacing characters with English?

  • .NET 2.0 Process Elevation for App Installation

    - by Brian Gillespie
    We have an application written in both C++ and .NET that installs for all users in the Program Files folder. This application downloads new versions of itself (as MSI installers) and spawns the new installer process to replace itself. The install process as it exists today: Copy an install manager app (C#, .NET 2.0) to the temp directory. Call this 'Manager' Manager is executed with elevated privs per this article. The original application exits. Manager spawns the MSI installer (with elevated privs, since the copy is elevated) Manager spawns the new version of the app. The bug: The newly installed app is running in an elevated state. This causes problems I won't enumerate here. Ideally, the launch of the newly installed app would be run with the permissions of the original user. I can't figure out how to demote the app back to being the standard user after elevation. An inelegant hack: (yeah, yeah, this whole process is inelegant anyway) Copy the install manager to the temp directory Run the install manager with standard user privs. Lets call this instance 'LowlyManager'. Original application exits. LowlyManager spawns the app again, this time with elevated privs. Let's name this instance 'UpperManagement' UpperManagement spawns the installer UpperManagement exits gracefully, returning the exit code of the installer. LowlyManager interprets the error code from UpperManagement, and spawns the newly installed application. This time as the original invoker. Is there a better way to do this? (I've left out a bunch of other details before and after these steps that make the process smoother for the user, but this should be enough to understand the core of the problem I'm trying to solve.) Other requirements: We can't install as a per-user app The user shouldn't be presented with an authentication dialog box if UAC would have simply asked "are you sure you want to allow this?". I think this might kill a solution using WindowsImpersonationContext, but I'm not sure. The system needs to work on XP, Vista, and Windows 7 (even if there is a separate process for XP).

  • Best Practices / Patterns for Enterprise Protection/Remediation of SSNs (Social Security Numbers)

    - by Erik Neu
    I am interested in hearing about enterprise solutions for SSN handling. (I looked pretty hard for any pre-existing post on SO, including reviewing the terriffic SO automated "Related Questions" list, and did not find anything, so hopefully this is not a repeat.) First, I think it is important to enumerate the reasons systems/databases use SSNs: (note—these are reasons for de facto current state—I understand that many of them are not good reasons) Required for Interaction with External Entities. This is the most valid case—where external entities your system interfaces with require an SSN. This would typically be government, tax and financial. SSN is used to ensure system-wide uniqueness. SSN has become the default foreign key used internally within the enterprise, to perform cross-system joins. SSN is used for user authentication (e.g., log-on) The enterprise solution that seems optimum to me is to create a single SSN repository that is accessed by all applications needing to look up SSN info. This repository substitutes a globally unique, random 9-digit number (ASN) for the true SSN. I see many benefits to this approach. First of all, it is obviously highly backwards-compatible—all your systems "just" have to go through a major, synchronized, one-time data-cleansing exercise, where they replace the real SSN with the alternate ASN. Also, it is centralized, so it minimizes the scope for inspection and compliance. (Obviously, as a negative, it also creates a single point of failure.) This approach would solve issues 2 and 3, without ever requiring lookups to get the real SSN. For issue #1, authorized systems could provide an ASN, and be returned the real SSN. This would of course be done over secure connections, and the requesting systems would never persist the full SSN. Also, if the requesting system only needs the last 4 digits of the SSN, then that is all that would ever be passed. Issue #4 could be handled the same way as issue #1, though obviously the best thing would be to move away from having users supply an SSN for log-on. There are a couple of papers on this: UC Berkely: http://bit.ly/bdZPjQ Oracle Vault: bit.ly/cikbi1

  • Set maven to use archiva repositories WITHOUT using activeByDefault?

    - by Sam Levin
    I am very close to finally having a working setup with archiva and maven. The last thing that's really boggling me, is how to set up my internal and snapshot repositories - without using a profile which contains activeByDefault set to true. I am using a SUPER super pom - a company-wide pom which contains distributionManagement information for releases. I was thinking that I could specify the repositories in this pom, and configure the authentication settings in settings.xml? Can I use repositories tag without a profile? There should be no "profile" for my internal and snapshot repositories, as they will never change... What I'm trying to steer clear from, is using a "default" profile, which is active all the time. I hear activeByDefault is NOT a best practice and I don't intend to use it. With that said, how should I go about doing this? My internal repo is a mirror of the maven central repo, so I would like to lock down my developers to ONLY use our internal artifact server. Remember - I do NOT want a profile with activeByDefault set to true. I cannot stress this enough! Should I use Maven mirrors? Should I "add" additional repositories? If I take the repositories tag instead of the mirrors tag, will maven force builds to use ONLY my archiva settings, instead of the default maven central? Or is what I seek to accomplish able to be done using only the mirrors tag in maven? I know how to configure repo credentials when using repositories tag, but not with mirrors. How is this done? Is providing credentials for anything in mirrors tags the same as for anything in repositories tags? Am I missing something obvious? I've had it up to here with getting things up and running using maven. I know it will be worthwhile in the end, but it is surely causing me a ton of aggravation and resources seem to be sparse. Either that, or people are content using it however they please without regard to best-practices. Thank you

  • jQuery, get datas in AJAX (done) then, display them as star (error)

    - by Tristan
    Hello, In my website, there are 2 steps : I get values from another domain with AJAX, it's numbers 100% working Then, i want to display those numbers in stars with this plugin (http://stackoverflow.com/questions/1987524/turn-a-number-into-star-rating-display-using-jquery-and-css) The error : the stars plugin does not work for the value i recieve from my ajax request, but it's working for my values for my domain which are not JS manipulated you can see a demo here http://www.esl.eu/fr/test/test_atome/?killcache=true PS: the data in ajax are provided in JSON-P so i wrote a parser which look like this: jQuery.ajax({ type: "get", dataType: "jsonp", url: "http://www.foo.com/", data: {demandeur: "monkey" }, cache: true, success: function(data, textStatus, XMLHttpRequest){ var obj = null, length = data.length; for (var i = 0; i < length; i++) { widget = "<p>AVERAGES<p>"; widget += "<p><span class='stars'>"; widget += data[i].services; widget += "</span></p>"; widget += "<p><span class='stars'>"; widget += data[i].qualite; widget += "</span></p>"; jQuery('#gotserv').html(widget); } } }); }); Then i have the star plugin after this function : $.fn.stars = function() { $(this).each(function() { // Get the value var val = parseFloat($(this).html()); // Make sure that the value is in 0 - 5 range val = val 5 ? 5 : (val < 0 ? 0 : val); // Calculate physical size var size = 16 * val; // Create stars holder var stars = $(''); // Adjust yellow stars' width stars.find('span').width(size); // Replace the numerical value with stars $(this).replaceWith(stars); }); I hope you understand, i don't know if i'm clear Thank you

  • Accidental Complexity in OpenSSL HMAC functions

    - by Hassan Syed
    SSL Documentation Analaysis This question is pertaining the usage of the HMAC routines in OpenSSL. Since Openssl documentation is a tad on the weak side in certain areas, profiling has revealed that using the: unsigned char *HMAC(const EVP_MD *evp_md, const void *key, int key_len, const unsigned char *d, int n, unsigned char *md, unsigned int *md_len); From here, shows 40% of my library runtime is devoted to creating and taking down **HMAC_CTX's behind the scenes. There are also two additional function to create and destroy a HMAC_CTX explicetly: HMAC_CTX_init() initialises a HMAC_CTX before first use. It must be called. HMAC_CTX_cleanup() erases the key and other data from the HMAC_CTX and releases any associated resources. It must be called when an HMAC_CTX is no longer required. These two function calls are prefixed with: The following functions may be used if the message is not completely stored in memory My data fits entirely in memory, so I choose the HMAC function -- the one whose signature is shown above. The context, as described by the man page, is made use of by using the following two functions: HMAC_Update() can be called repeatedly with chunks of the message to be authenticated (len bytes at data). HMAC_Final() places the message authentication code in md, which must have space for the hash function output. The Scope of the Application My application generates a authentic (HMAC, which is also used a nonce), CBC-BF encrypted protocol buffer string. The code will be interfaced with various web-servers and frameworks Windows / Linux as OS, nginx, Apache and IIS as webservers and Python / .NET and C++ web-server filters. The description above should clarify that the library needs to be thread safe, and potentially have resumeable processing state -- i.e., lightweight threads sharing a OS thread (which might leave thread local memory out of the picture). The Question How do I get rid of the 40% overhead on each invocation in a (1) thread-safe / (2) resume-able state way ? (2) is optional since I have all of the source-data present in one go, and can make sure a digest is created in place without relinquishing control of the thread mid-digest-creation. So, (1) can probably be done using thread local memory -- but how do I resuse the CTX's ? does the HMAC_final() call make the CTX reusable ?. (2) optional: in this case I would have to create a pool of CTX's. (3) how does the HMAC function do this ? does it create a CTX in the scope of the function call and destroy it ? Psuedocode and commentary will be useful.

  • How to communicate between Client and Server in a Client-Server Application?

    - by Sanoj
    I would like to implement an Client-Server Application, where the business-logic, security validations and a database are at the server and the user interface are at the client. I would like to implement clients in different languages i.e. one in WPF/.NET, one Swing/Java , one in Android/Java and maybe one HTML/JavaScript client. The server will be on Internet, so I would like to be able to have encrypted communication. The client will send some lists of items to be added to the database, or update items, and do some transactions. The server will check if the items are already updated by another client, or update the item, add new items or delete items. How do I solve the communication between clients and the server in such a system? I have been thinking about: http/https webserver, and sending messages in JSON or XML and use Web Sockets for bi-directional communication. Use http in a RESTful way, except when WebSockets are needed. But I guess there are better solutions for native desktop applications than http? CORBA - I have just heard about it, and it's old and complex. Not much talk about it these days. XMPP/Jabber - I have just heard about it and I don't know if it fits me at all. EJabberd seams to be a popular implementation. AMQP - I have just heard about it and I don't know if it fits me at all. RabbitMQ seams to be a popular implementation. Windows Communication Foundation, Java RMI, Java Message Service - but are they language independent? I guess some of these alternatives are on different levels, maybe I can have i.e xmpp or amqp in web sockets over https? What technologys are used for this problem in companies today? and what is recommended to use? I have no experience of them other than webservers and http. Please give me some guidance in this jungle. What are the pros and cons of these technologies in my situation?

  • What to Return? Error String, Bool with Error String Out, or Void with Exception

    - by Ranger Pretzel
    I spend most of my time in C# and am trying to figure out which is the best practice for handling an exception and cleanly return an error message from a called method back to the calling method. For example, here is some ActiveDirectory authentication code. Please imagine this Method as part of a Class (and not just a standalone function.) bool IsUserAuthenticated(string domain, string user, string pass, out errStr) { bool authentic = false; try { // Instantiate Directory Entry object DirectoryEntry entry = new DirectoryEntry("LDAP://" + domain, user, pass); // Force connection over network to authenticate object nativeObject = entry.NativeObject; // No exception thrown? We must be good, then. authentic = true; } catch (Exception e) { errStr = e.Message().ToString(); } return authentic; } The advantages of doing it this way are a clear YES or NO that you can embed right in your If-Then-Else statement. The downside is that it also requires the person using the method to supply a string to get the Error back (if any.) I guess I could overload this method with the same parameters minus the "out errStr", but ignoring the error seems like a bad idea since there can be many reasons for such a failure... Alternatively, I could write a method that returns an Error String (instead of using "out errStr") in which a returned empty string means that the user authenticated fine. string AuthenticateUser(string domain, string user, string pass) { string errStr = ""; try { // Instantiate Directory Entry object DirectoryEntry entry = new DirectoryEntry("LDAP://" + domain, user, pass); // Force connection over network to authenticate object nativeObject = entry.NativeObject; } catch (Exception e) { errStr = e.Message().ToString(); } return errStr; } But this seems like a "weak" way of doing things. Or should I just make my method "void" and just not handle the exception so that it gets passed back to the calling function? void AuthenticateUser(string domain, string user, string pass) { // Instantiate Directory Entry object DirectoryEntry entry = new DirectoryEntry("LDAP://" + domain, user, pass); // Force connection over network to authenticate object nativeObject = entry.NativeObject; } This seems the most sane to me (for some reason). Yet at the same time, the only real advantage of wrapping those 2 lines over just typing those 2 lines everywhere I need to authenticate is that I don't need to include the "LDAP://" string. The downside with this way of doing it is that the user has to put this method in a try-catch block. Thoughts? Is there another way of doing this that I'm not thinking of?
