  • Problem with ASP.NET Authentication

    - by Niels Bosma
    I'm having problem with our login procedure. Some customers complain that they can't login. I can see in our logs that their login is successful and that they are redirected from the login page to the member area. But there somehow the login isn't detected and they are bounced back to the login page. I've asked customers to check if cookies are supported (http://www.html-kit.com/tools/cookietester/) but problem remains even if this test returns true. This is how I've implemented the login procedure (simplyfied): protected void Login(string email, string password) { FormsAuthentication.SignOut(); Guid clientId = /* Validate login by checking email and password, if fails display error otherwise get client id */ FormsAuthentication.SetAuthCookie(clientId.ToString(), true); HttpContext.Current.Response.Redirect("~/Members.aspx"); } On the member page I check for authentication by in Page_Load function: public static void IsAuthenticated() { if (!HttpContext.Current.User.Identity.IsAuthenticated) { HttpContext.Current.Response.Redirect("~/Login.aspx", true); } } Maybe I'm using FormsAuthentication completely wrong? I've asked this before but still haven't been able to figure this out, I'd appreciate any help.

  • How reliable is DateTime.UtcNow in Silverlight applications?

    - by Edward Tanguay
    I have a silverlight application which users will be running in various time zones. These applications load their data from the server upon start up, then cache it in IsolatedStorage. When I make changes to the data on the server, I want to be able to change the "last updated time" so that all silverlight clients download the newest data the next time they check this date. However, I'm a bit confused as to how to handle the time zone issue since a if the server is in New York and the update time is set to 2010-01-01 17:00:00 and a client in Seattle checks compares it to its local time of 2010-01-01 14:00:00 it won't update and will continue to provide old data for three more hours. My solution is to always post the update time in UTC time, not with the time on the server, then make the Silverlight app check with DateTime.UtcNow. Is this as easy as it sounds or are their issues with this, e.g. that timezones are not set correctly on computers and hence the SilverlightApp does not report the correct UTC time. Can anyone say from experience how likely it is that using DateTime.UtcNow like this for cache refreshing will work in all cases? If DateTime.UtcNow is not reliable, I will just use an incremented "DataVersion" integer but there are other scenarios in which getting time zone sychronization down would make it useful to thoroughly understand how to solve this in silverlight apps.

  • JSF and CXF not working together

    - by Milan
    I want to make dynamic web service invoker in JSF with CXF. But when I load this simple code I get error. The code: JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance(); Client client = dcf.createClient("http://ws.strikeiron.com/IPLookup2?wsdl"); The error: No Factories configured for this Application. This happens if the faces-initialization does not work at all - make sure that you properly include all configuration settings necessary for a basic faces application and that all the necessary libs are included. Also check the logging output of your web application and your container for any exceptions! If you did that and find nothing, the mistake might be due to the fact that you use some special web-containers which do not support registering context-listeners via TLD files and a context listener is not setup in your web.xml. A typical config looks like this; org.apache.myfaces.webapp.StartupServletContextListener Caused by: java.lang.IllegalStateException - No Factories configured for this Application. This happens if the faces-initialization does not work at all - make sure that you properly include all configuration settings necessary for a basic faces application and that all the necessary libs are included.

  • Updating a Foreign Key constraint with ON DELETE CASCADE not updating?

    - by Alastair Pitts
    We've realised in our SQL Server 2005 DB that some Foreign Keys don't have the On Delete Cascade property set, which is giving us a couple of referential errors when we try and delete some records. Use the Management Studio I scripted the DROP and CREATESQL's, but it seems that the CREATE isn't working correctly. The DROP: USE [FootprintReports] GO IF EXISTS (SELECT * FROM sys.foreign_keys WHERE object_id = OBJECT_ID(N'[dbo].[FK__SUBSCRIPTIONS_Reports]') AND parent_object_id = OBJECT_ID(N'[dbo].[_SUBSCRIPTIONS]')) ALTER TABLE [dbo].[_SUBSCRIPTIONS] DROP CONSTRAINT [FK__SUBSCRIPTIONS_Reports] and the CREATE USE [FootprintReports] GO ALTER TABLE [dbo].[_SUBSCRIPTIONS] WITH CHECK ADD CONSTRAINT [FK__SUBSCRIPTIONS_Reports] FOREIGN KEY([PARAMETER_ReportID]) REFERENCES [dbo].[Reports] ([ID]) ON DELETE CASCADE GO ALTER TABLE [dbo].[_SUBSCRIPTIONS] CHECK CONSTRAINT [FK__SUBSCRIPTIONS_Reports] If I manually change the value of the On Delete in the GUI, after dropping and recreating, the On Delete isn't correctly updated. As a test, I set the Delete rule in the GUI to Set Null. It dropped correctly, and recreated without error. If I got back into the GUI, it is still showing the Set Null as the Delete Rule. Have I done something wrong? or is there another way to edit a constraint to add the ON DELETE CASCADE rule?

  • Handling 'session expired' in JSF web application, running in JBoss AS 5

    - by Veera
    This question is related to my other question "How to redirect to Login page when Session is expired in Java web application?". Below is what I'm trying to do: I've a JSF web application running on JBoss AS 5 When the user is inactive for, say 15 minutes, I need to log out the user and redirect him to the login page, if he is trying to use the application after the session has expired. So, as suggested in 'JSF Logout and Redirect', I've implemented a filter which checks for the session expired condition and redirects the user to a session-timed-out.jsp page, if the session has expired. I've added SessionExpiryCheckFilter on top of all other filter definitions in web.xml, so that my session expiry check will get the first hit always. Now comes the challenge I'm facing. Since I'm using JBoss AS, when the session expired, JBoss automatically redirects me to the login page (note that the session expiry check filter is not invoked). So, after I log-in, my SessionExpiryCheckFilter intercepts the request, and it sees a session is available. But, it throws the exception javax.faces.application.ViewExpiredException: viewId:/mypage.faces - View /mypage.faces could not be restored. Have anyone faced this issue before? Any ideas to solve this issue?

  • Best way to enforce inter-table constraints inside database

    - by FerranB
    I looking for the best way to check for inter-table constraints an step forward of foreing keys. For instance, to check if a date child record value is between a range date on two parent rows columns. For instance: Parent table ID DATE_MIN DATE_MAX ----- ---------- ---------- 1 01/01/2009 01/03/2009 ... Child table PARENT_ID DATE ---------- ---------- 1 01/02/2009 1 01/12/2009 <--- HAVE TO FAIL! ... I see two approaches: Create materialized views on-commit as shown in this article (or other equivalent on other RDBMS). Use stored-procedures and triggers. Any other approach? Which is the best option? UPDATE: The motivation of this question is not about "putting the constraints on database or on application". I think this is a tired question and anyone does the way she loves. And, I'm sorry for detractors, I'm developing with constraints on database. From here, the question is "which is the best option to manage inter-table constraints on database?". I'm added "inside database" on the question title. UPDATE 2: Some one added the "oracle" tag. Of course materialized views are oracle-tools but I'm interested on any option regardless it's on oracle or others RDBMSs.

  • How to set SQL_BIG_SELECTS = 1 from VB(legacy ASP) with ADODB environment?

    - by conecon
    I encountered The SELECT would examine more than MAX_JOIN_SIZE rows; check your WHERE and use SET SQL_BIG_SELECTS=1 or SET SQL_MAX_JOIN_SIZE=# if the SELECT is okay error with my ASP code. ASP code has server side ADODB connection with MySQL and connection seems not be able to execute multiple query. How to implement SQL_BIG_SELECTS = 1 in my code? Set obj_db = Server.CreateObject("ADODB.Connection") Session("ConnectionString") = "dsn=dsn1016189_mysql;uid=apns;pwd=mypassword;DATABASE=mydb;APP=ASP Script;STMT=SET CHARACTER SET SJIS" obj_db.Open Session("ConnectionString") Set obj_ret = Server.CreateObject("ADODB.Recordset") obj_ret.CursorLocation = 3 and executing SQL...

  • MS Source Server - source stream is apparently not there when viewing with srctool

    - by Tim Peel
    Hi, I have been playing around with the MS Source Server stuff in the MS Debugging Tools install. At present, I am running my code/pdbs through the Subversion indexing command, which is now running as expected. It creates the stream for a given pdb file and writes it to the pdb file. However when I use that DLL and associated pdb in visual studio 2008, it says the source code cannot be retrieved. If I check the pdb against srctool is says none of the source files contained are indexed, which is very strange as the process prior ran fine. If I check the stream that was generated from the svnindex.cmd run for the pdb, srctool says all source files are indexed. Why would there be a difference? I have opened the pdb file in a text editor and I can see the original references to the source files on my machine (also under the srcsrv header name) and the new "injected" source server links to my subversion repository). Should both references still exist in the pdb? I would have expected one to be removed? Either way, visual studio 2008 will not pick up my source references so I am a bit lost as to what to try next. As far as I can tell, I have done everything I should have. Anyone have similar experiences? Many thanks.

  • Prevent Navigation to CreateUserWizardStep in the Postback event of nextbutton

    - by Aparna
    I am working with CreateUserWizard tool for creating a registration page. This is the first time and I am encountering problem with the following: I defined two steps in WizardSteps in the page: <WizardSteps> <asp:WizardStep ID="CreateUserWizardStep0" runat="server" Title="Sign Up for your new Account !!"> <asp:TextBox ID="Email" runat="server"> In the first wizard step, the user provides email, and we need to check if this email meets certain criteria (if he exists in our internal database, country is US etc) and if he/she is eligible navigate to CreateUserWizardStep1. I have a StartNextButton in the Start Navigation template for the WizardStep0. <StartNavigationTemplate> <br /> <asp:Button ID="StartNextButton" runat="server" CommandName="MoveNext" OnClick="StartNextButton_Click" Text="Check My Eligibility" /> </StartNavigationTemplate> I do all the logic of checking eligibility in the post-back event OnClick="StartNextButton_Click . If he is not eligible, I should display the error message in the step0 textbox and prevent navigation to CreateUserWizardStep1. I tried the following: if(noteligible) { lblError1.Visible = true; lblError1.Text = this.hfUserAlreadyRegistered.Value.ToString(); this.CreateUserWizard1.ActiveStepIndex = this.CreateUserWizard1.WizardSteps.IndexOf(this.CreateUserWizardStep0); this.CreateUserWizard1.Controls.Remove(CreateUserWizardStep1); this.CreateUserWizard1.ActiveStepIndex = 0; break; } But this is not working. I am taken out of step0 and step1 is coming irrespective of this. How can I just remain in Step0 and display the error message when the user is not eligible and navigate to Step1 only when he is eligible to register ? Thank you very much.

  • Unittesting aspect-oriented features.

    - by Tomas Brambora
    Hi, I'd like to know what would you propose as the best way to unit test aspect-oriented application features (well, perhaps that's not the best name, but it's the best I was able to come up with :-) ) such as logging or security? These things are sort of omni-present in the application, so how to test them properly? E.g. say that I'm writing a Cherrypy web server in Python. I can use a decorator to check whether the logged-in user has the permission to access a given page. But then I'd need to write a test for every page to see whether it works oK (or more like to see that I had not forgotten to check security perms for that page). This could maybe (emphasis on maybe) be bearable if logging and/or security were implemented during the web server "normal business implementation". However, security and logging usually tend to be added to the app as an afterthough (or maybe that's just my experience, I'm usually given a server and then asked to implement security model :-) ). Any thoughts on this are very welcome. I have currently 'solved' this issue by, well - not testing this at all. Thanks.

  • JavaScript: input validation in the keydown event

    - by c411
    Hi, I'm attempting to do info validation against user text input in the process of keydown event. The reason that I am trying to validate in the keydown event is because I do not want to display the characters those that are considered to be illegal in the input box at the beginning. The validation I am writing is like this, function validateUserInput(){ var code = this.event.keyCode; if ((code<48||code>57) // numerical &&code!==46 //delete &&code!==8 //back space &&code!==37 // <- arrow &&code!==39) // -> arrow { this.event.preventDefault(); } } I can keep going like this, however I am seeing drawbacks on this implmentation. Those are, for example, Conditional statement become longer and longer when I put more conditions to be examined. keyCodes can be different by browsers. I have to not only check what is not legal but also have to check what are exceptionals. In above examples, delete,backspace, and arrow keys are exceptionals. But the feature that I don't want to lose is having not to display the input in the textarea unless it passes the validation. (In case the user try to put illegal characters in the textarea, nothing should appear at all) That is why I am not doing validation upon keyup event. So my question is, Are there better ways to validate input in keydown event than checking keyCode by keyCode? Are there other ways to capture the user inputs other than keydown event before browser displays it? And a way to put the validation on it? Thanks for the help in advance.

  • jQuery show based on checkbox value at page load.

    - by Jacob Huggart
    I have an ASP MVC web app and on one of the pages there is a set of Main checkboxes with sub-checkboxes underneath them. The sub-checkboxes should only show up when the corresponding main checkbox is checked. I have the following code that works just fine as long as none of the checkboxes are checked when the page loads. $("input[id$=Suffix]").change(function() { prefix = this.id; if (!$(this).hasClass("checked")) { $("tr[id^=" + prefix + "]").show(); $(this).addClass("checked"); } else { $("tr[id^=" + prefix + "]").hide(); $(this).removeClass("checked"); } }); Now I need to check a database for the values of the main checkboxes. I get the values, and can check the boxes on page load. But when the page comes up, the sub-checkboxes are not displayed when the main checkbox is checked. Also, if the main checkbox is checked when the page loads, the sub-checkboxes are only displayed when the main chcekbox is unchecked (obviously because the above function only acts on .change()). What do you all suggest I try? If you need further explanation feel free to ask. edit: btw, all of this is in $(document).ready()

  • Nested Groups in Regex

    - by cryptic-star
    I'm constructing a regex that is looking for dates. I would like to return the date found and the sentence it was found in. In the code below, the strings on either side of date_string should check for the conditions of a sentence. For your sake, I've omitted the regex for date_string - sufficed to say, it works for picking out dates. While the inside of date_string isn't important, it is grouped as one entire regex. "((?:[^.|?|!]*)"+date_string+"(?:[^.|?|!]*[.|?|!]\s*))" The problem is that date_string is only matching the last number of any given date, presumably because the regex in front of date_string is matching too far and overrunning the date regex. For example, if I say "Independence Day is July 4.", I will get the sentence and 4, even though it should match 'July 4'. In case you're wondering, my regex inside date_string are ordered in such a way that 'July 4' should match first. Is there any way to do this all in one regex? Or do I need to split it up somehow (i.e. split up all text into sentences, and then check each sentence)?

  • Jquery CheckBox Selection/Deselection optimally given X checkboxes

    - by Amitd
    Hi guys, I have suppose say 'X' check-boxes(any input elements) in a Form and "M" option selection indexes ("M" less than equal to "X"). then how do i select the "M" option indexes/values and deselect the rest of check-boxes optimally? i.e.Suppose I have 10 Checkboxes and 5 Option Indices(eg: 1,2,4,5,8) then i have to select checkboxes with given index . I could come up with the following code: HTML: <div id="Options"> <input id="choice_1" type="checkbox" name="choice_1" value="Option1"><label for="choice_1">Option1</label> <input id="choice_2" type="checkbox" name="choice_2" value="Option2"><label for="choice_2">Option2</label> <input id="choice_3" type="checkbox" name="choice_3" value="Option3"><label for="choice_3">Option3</label> .. ..till choice_10 </div> IN JS: //Have to select checkboxes with "Value" in choicesToSelect and give a selection //effect to its label var choicesToSelect={"Option1","Option9","Option3","Option4","Option2"}; selectHighlightCheckBoxes(choicesToSelect); function selectHighlightCheckBoxes(choices){ $.each( choices, function(intIndex, objValue) { //select based on id or value or some criteria var option = $("#Options :input[value=" + objValue + "]") ; if ($(option).is("input[type='radio']") || $(option).is("input[type='checkbox']")) { $(option).attr('checked', true); $(option).next('label:first').css({ 'border': '1px solid #FF0000', 'background-color': '#BEF781', 'font-weight': 'bolder' }); } else if ($(option).is("input[type='text']")) { $(option).css({ 'border': '1px solid #FF0000', 'background-color': '#BEF781', 'font-weight': 'bolder' }); } else { } } ); } But i want to also add effect to the rest (not in choicesToSelect array) also. (may be red color to those not in choiceToSelect) Can this be done in the one traversal/loop? Optimally? or Better way?

  • What issues to consider when rolling your own data-backend for Silverlight / AJAX on non-ASP.NET ser

    - by Edward Tanguay
    I have read-only Silverlight and AJAX apps which read static text and XML files from a PHP/Apache server, which works very nicely with features such as asynchronous loading, lazy-loading only what I need for each page, loading in the background, developed a little query language to get a PHP script to create custom XML files etc. it's pragmatic read-only REST, and all works fast and fine for read-only sites. Now I want to also add the ability to write data from these apps to a database on the same PHP/Apache server. For those of you who have built similar data-access layers, what do I need to consider while building this, especially regarding security so that not just any client can write and alter my database, e.g.: check HTTP_USER_AGENT for security check REMOTE_ADDR for security require a special code for security, perhaps a list of TAN codes (such as banks use for online transactions) each which can only be used once, both the client and server have these I wonder if there is some kind of standard REST query I should lean on for e.g. building SQL-like statements in the URL parameters, e.g. http://www.thedatalayersite.com/query?insertinto=customers&... Any thoughts, notes from experience, ideas, gotchas, especially ideas on tightening down security in this endeavor would be helpful.

    Hi, i have a problem. I want to upload a file with plupload with the HML5 runtime. This is my html/js code : jQuery(function(){ jQuery("#uploader").pluploadQueue({ // General settings runtimes : 'html5', name : 'file', url : 'http://server.name/addContent', max_file_size : '${maxSize}$_("GB")', }); jQuery('#form_upload_file').submit(function(e) { var uploader = jQuery('#uploader').pluploadQueue(); // Validate number of uploaded files if (uploader.total.uploaded == 0) { // Files in queue upload them first if (uploader.files.length > 0) { // When all files are uploaded submit form uploader.bind('UploadProgress', function() { if (uploader.total.uploaded == uploader.files.length) jQuery('#form_upload_file').submit(); }); uploader.start(); } else alert('You must at least upload one file.'); e.preventDefault(); } }); }); <form id="form_upload_file" action="#" method="POST"> <div id="uploader"></div> <input type="hidden" name="token" value="token" /> <input type="hidden" name="idUser" value="$idUser" /> </form> So, when i click in the button to upload(the submit() method is not called), it does an OPTIONS HTTP request to my server so i don't know what i must do to save the file? this is my webpy code : def OPTIONS(self): web.header('Content-type', 'text/plain: charset=utf-8') web.header('Cache-Control', 'no-store, no-cache, must-revalidate') web.header('Cache-Control', 'post-check=0, pre-check=0', False) web.header('Pragma', 'no-cache') def POST(self): input = web.input(_unicode=False, file={})#on récupère les input self.copy(input.file.file) etc. any idea ? thanks.

  • Google App Engine - Caching generated HTML

    - by Alexander
    I have written a Google App Engine application that programatically generates a bunch of HTML code that is really the same output for each user who logs into my system, and I know that this is going to be in-efficient when the code goes into production. So, I am trying to figure out the best way to cache the generated pages. The most probable option is to generate the pages and write them into the database, and then check the time of the database put operation for a given page against the time that the code was last updated. Then, if the code is newer than the last put to the database (for a particular HTML request), new HTML will be generated and served, and cached to the database. If the code is older than the last put to the database, then I will just get the HTML direct from the database and serve it (therefore avoiding all the CPU wastage of generating the HTML). I am not only looking to minimize load times, but to minimize CPU usage. However, one issue that I am having is that I can't figure out how to programatically check when the version of code uploaded to the app engine was updated. I am open to any suggestions on this approach, or other approaches for caching generated html. Note that while memcache could help in this situation, I believe that it is not the final solution since I really only need to re-generate html when the code is updated (as opposed to every time the memcache expires). Kind Regards, and thank you in advance for any suggestions you may be able to offer. -Alex

  • Tinyurl API Example - Am i doing it right :D

    - by Paul Weber
    Hi ... we use super-long Hashes for the Registration of new Users in our Application. The Problem is that these Hashes break in some Email Clients - making the Links unusable. I tried implementing the Tinyurl - API, with a simple Call, but i think it times out sometimes ... sometimes the mail does not reach the user. I updated the Code, but now the URL is never converted. Is Tinyurl really so slow or am i doing something wrong? (I mean hey, 5 Seconds is much in this Times) Can anybody recommend me a more reliable service? All my Fault, forgot a false in the fopen. But i will leave this sample of code here, because i often see this sample, wich i think does not work very reliable: return file_get_contents('http://tinyurl.com/api-create.php?url='.$u); This is the - i think fully working sample. I would like to hear about Improvements. static function gettinyurl( $url ) { $context = stream_context_create( array( 'http' => array( 'timeout' => 5 // 5 Seconds should be enough ) ) ); // get tiny url via api-create.php $fp = fopen( 'http://tinyurl.com/api-create.php?url='.$url, 'r', $context); // open (read) api-create.php with long url as get parameter if( $fp ) { // check if open was ok $tinyurl = fgets( $fp ); // read response if( $tinyurl && !empty($tinyurl) ) // check if response is ok $url = $tinyurl; // set response as url fclose( $fp ); // close connection } // return return $url; // return (tiny) url }

    Here is a test framework to show what I am doing, just create a new project add a tabbed control, on tab 1 put a button on tab 2 put a check box (default names) and paste this code for its code public partial class Form1 : Form { private List<bool> boolList = new List<bool>(); BindingSource bs = new BindingSource(); public Form1() { InitializeComponent(); boolList.Add(false); bs.DataSource = boolList; checkBox1.DataBindings.Add("Checked", bs, ""); } bool updating = false; private void button1_Click(object sender, EventArgs e) { updating = true; boolList[0] = true; bs.ResetBindings(false); Application.DoEvents(); updating = false; } private void checkBox1_CheckedChanged(object sender, EventArgs e) { if (!updating) MessageBox.Show("CheckChanged fired outside of updating"); } } The issue is if you run the program and look at tab 2 then press the button on tab 1 the program works as expected, however if you press the button on tab 1 then look at tab 2 the event for the checkbox will not fire untill you look at tab 2. The reason for this is the controll on tab 2 is not in the "created" state, so its binding to change the checkbox from unchecked to checked does not happen until after the control has been "Created". checkbox1.CreateControl() does not do anything because according to MSDN CreateControl does not create a control handle if the control's Visible property is false. You can either call the CreateHandle method or access the Handle property to create the control's handle regardless of the control's visibility, but in this case, no window handles are created for the control's children. I tried getting the value of Handle(there is no CreateHandle for Button) but still the same result. Any suggestions other than have the program quickly flash all of my tabs that have data-bound check boxes when it first loads?

  • Does mod_php honor HEAD requests properly?

    - by rkulla
    The HTTP/1.1 RFC stipulates "The HEAD method is identical to GET except that the server MUST NOT return a message-body in the response." I know Apache honors the RFC but modules don't have to. My question is, does mod_php5 honor this? The reason I ask is because I just came across an article saying that PHP developers should check this themselves with: if (stripos($_SERVER['REQUEST_METHOD'], 'HEAD') !== FALSE) { exit(); } but seeing as how browsers send HEAD requests for cache checking it seems unlikely to me that no book, docs, etc., advise PHP developers to do this check. I googled a second and not much turned up, other than some people saying they try to strange things like mod_rewrite/redirect after getting HEAD requests and some old bug ticket from like 2002 claiming that mod_php still executed the rest of the script by default. So I just ran a quick test by using PECL::HTTP to run http_head('http://mysite.com/test-head-request.php'); while having: <?php error_log('REST OF SCRIPT STILL RAN'); ?> in test-head-request.php to see if the rest of the script still executed, and it didn't. I figure that should be enough to settle it, but want to get more feedback and maybe help clear up confusion for anyone else who has wondered about this. So if anyone knows off the top of their head (no pun intended) - or have any conventions they use for receiving HEAD requests, that'd be great. Otherwise, I'll grep the C source later and respond in a comment with my findings. Thanks.

  • SharePoint Designer Workflow: Unruly 'Collect User Data' Action

    - by Jeremy
    I'm a student in a SharePoint class online. This problem has riddled everyone I've discussed it with, including the teacher. There seems to be some sort of problem when I create a workflow with the collect data action. I can create workflows that send e-mails and use the other actions just fine. What could be causing this problem? My reproduction steps are simple: Create a new Site Collection with the Blank Site template. Create a new Custom List. In SharePoint Designer, start a new workflow on the Custom List. Add the collect data action to the workflow. Set the user to the one that created the task. Set the data to anything. A single check box, a string, Choice, doesn't matter. Leave the output variable as default. Mystery error appears! When the Check Workflow button is pressed, nothing happens. No message box appears at all. The warning icon in the Steps panel merely points out that there are some errors, it isn't specific as to what they are. Additionally, when I click on the data object again after it's been created, it doesn't populate the form with the old values. It goes back to the default name with no fields. So there's definitely something going wrong here. I've narrowed the problem down to the data object, but I don't know what to do about it. The workflow acts like normal for other activities. For example, delete the Collect Data action and add a Send Email one instead and it compiles and runs successfully.

  • How do I find out what process Id and thread id / name has a file open

    - by peter
    Hi All, I am using C# in an application and am having some problems with a file becoming locked. The piece of code does this, while (true) { Read a packet from a socket (with data in it to add to the file) Open a file Writes data to it Close a file } But in the process the file becomes locked. I don't really understand how, we are are definately catching and reporting exceptions so I don't see how the file doesn't get closed every time. My best guess is that something else is opening the file, but I want to prove it. Can someone please provide a piece of code to check whether the file is open and if so report what processid and threadid has the file open. For example if I had this code, StreamWriter streamWriter1 = new StreamWriter(@"c:\logs\test.txt"); streamWriter1.WriteLine("Test"); // code to check for locks?? StreamWriter streamWriter2 = new StreamWriter(@"c:\logs\test.txt"); streamWriter1.Close(); streamWriter2.Close(); That will throw an exception because the file is locked when we try and open it the second time. So where the comment is what could I put in there to report that the current app (process Id) and the current thread (thread Id) have the file locked? Thanks.

  • PHP Switch and Login

    - by Steve Rivera
    I'm fairly new with PHP and I am messing around with a login/registration system. I setup my sample website using a PHP-SWITCH script I found a while back: <?php switch($_GET['id']) { default: include('home.php'); /* LOGIN PAGES */ break; case "register_form": include ('includes/user_system/register_form.php'); } ? On the registration page the form links to my "register.php" which checks the validity of the form and to check for any blank fields and so on. "register.php" is supposed to refresh the page and add a reason to what the user did wrong when submitting the form. On my "register_form.php" page, which holds the actual form. This field is hidden until the user makes a mistake. <?php if (isset($reg_error)) { ?> , please try again. My "register.php" checks the form for all the errors. Here's the bit of code that will refresh the page with the reason for the error: // Check if any of the fields are missing if (empty($_POST['username']) || empty($_POST['password']) || empty($_POST['confirmpass'])) { // Reshow the form with an error $reg_error = 'One or more fields missing'; include 'register_form.php'; Now after I submit the form without any fields filled out I get the error code, but it refreshes to the actual "register_form.php". The problem with this is that because of my PHP-SWITCH script (helps me manage the site a lot easier) I don't have any formatting on that page. The actual URL to my "register_form.php" would be: "index.php?id=register_form.php". Now I have tried several different things such as changing it to: include 'index.php?id=register_form.php' And also changing it to: header(location:index.php?id=register_form.php') Unfortunately all this does is refresh the page without the reason for the error. I know this can be easily solved by just adding a Javascript Validator but I'd like to know if it is possible to refresh the page with the error using either "include" or "header()" while having a PHP-SWITCH script on the website.
