• Rails Heroku Gemfile.lock error - push rejected (open source)

  - by KJ50

  I am trying to push my open source RoR application to Heroku but I'm having an issue making the initial push. I have read many similar questions, but none of those answers has helped to solve my problem. I have tried bundle update and bundle install various times. I also have tried removing and then re-committing my Gemfile.lock file, however I get this same error still... $ git push heroku master Counting objects: 5199, done. Compressing objects: 100% (3086/3086), done. Writing objects: 100% (5199/5199), 4.57 MiB | 131 KiB/s, done.

If anyone has any insight which could help me resolve this issue I would be very thankful!

• Enforce link in Team foundation server bug work item for duplicates

  - by Tewr

  We have just started out with Team Foundation Server 2008 / Visual Studio Team System and we are pleased to find how we can export and modify work items to our needs. However, this last thing that would make the setup perfect for us has proved somewhat difficult: We have exported the Bug work item type and have made modifications to it to appear differently to different groups of users. We do, however, see a potential problem in non-developers reporting bugs which turn out to be duplicates. We would like to enforce that users who close a ticket with resolved reason:duplicate also creates a link to the bug which is perceived as the first bug report. I have looked at System.RelatedLinkCount, and put the rule <FIELD type="Integer" name="RelatedLinkCount" refname="System.RelatedLinkCount"> <WHEN field="Microsoft.VSTS.Common.ResolvedReason" value="duplicate"> <PROHIBITEDVALUES> <LISTITEM value="0" /> </PROHIBITEDVALUES> </WHEN> </FIELD> However, when I try to put anything in that scope, the importer tells me that System.RelatedLinkCount does not accept the rule, no matter what I put, but the rule above shows what I am trying to do (even though the most preferable rule would also check that the bug that I link to is not a duplicate as well, though this is overkill :P) Has anyone else tried to enforce rules like this in work items? Is there another approach to solving the same issue? I am thankful for any thoughts on the matter.

• PyQt - How to connect multiple signals to the same widget

  - by Orchainu

  [ ]All1 [ ]All2 [ ]checkbox1A [ ]checkbox1B [ ]checkbox2A [ ]checkbox2B Based on the chart above, a few things need to happen: The All checkboxes only affect the on/off of the column it resides in, and checks on/off all the checkboxes in that column. All checkboxes work in pairs, so if checkbox1A is on/off, checkbox1B needs to be on/off If an All checkbox is checked on, and then the user proceeds to check off one or more checkbox in the column, the All checkbox should be unchecked, but all the checkboxes that are already checked should remain checked. So really this is more like a chain reaction setup. If checkbox All1 is on, then chieckbox1A and 2A will be on, and because they are on, checkbox1B and 2B are also on, but checkbox All2 remains off. I tried hooking up the signals based on this logic, but only the paired logic works 100%. The All checkbox logic only works 50% of the time, and not accurately, and there's no way for me to turn off the All checkbox without turning all already checked checkboxes off. Really really need help ... T-T Sample code: cbPairKeys = cbPairs.keys() for key in cbPairKeys: cbOne = cbPairs[key][0][0] cbTwo = cbPairs[key][1][0] cbOne.stateChanged.connect(self.syncCB) cbTwo.stateChanged.connect(self.syncCB) def syncCB(self): pairKeys = cbPairs.keys() for keys in pairKeys: cbOne = cbPairs[keys][0][0] cbOneAllCB = cbPairs[keys][0][4] cbTwo = cbPairs[keys][1][0] cbTwoAllCB = cbPairs[keys][1][4] if self.sender() == cbOne: if cbOne.isChecked() or cbTwoAllCB.isChecked(): cbTwo.setChecked(True) else: cbTwo.setChecked(False) else: if cbTwo.isChecked() or cbOneAllCB.isChecked(): cbOne.setChecked(True) else: cbOne.setChecked(False) EDIT Thanks to user Avaris's help and patience, I was able to reduce the code down to something much cleaner and works 100% of the time on the 1st and 2nd desired behavior: #Connect checkbox pairs cbPairKeys = cbPairs.keys() for key in cbPairKeys: cbOne = cbPairs[key][0][0] cbTwo = cbPairs[key][1][0] cbOne.toggled.connect(cbTwo.setChecked) cbTwo.toggled.connect(cbOne.setChecked) #Connect allCB and allRO signals cbsKeys = allCBList.keys() for keys in cbsKeys: for checkbox in allCBList[keys]: keys.toggled.connect(checkbox.setChecked) Only need help on turning off the All checkbox when the user selectively turns off the modular checkboxes now

• Apply [ThreadStatic] attribute to a method in external assembly

  - by Sen Jacob

  Can I use an external assembly's static method like [ThreadStatic] method? Here is my situation. The assembly class (which I do not have access to its source) has this structure public class RegistrationManager() { private RegistrationManager() {} public static void RegisterConfiguration(int ID) {} public static object DoWork() {} public static void UnregisterConfiguration(int ID) {} } Once registered, I cannot call the DoWork() with a different ID without unregistering the previously registered one. Actually I want to call the DoWork() method with different IDs simultaneously with multi-threading. If the RegisterConfiguration(int ID) method was [ThreadStatic], I could have call it in different threads without problems with calls, right? So, can I apply the [ThreadStatic] attribute to this method or is there any other way I can call the two static methods same time without waiting for other thread to unregister it? If I check it like the following, it should work. for(int i=0; i < 10; i++) { new Thread(new ThreadStart(() => Checker(i))).Start(); } public string Checker(int i) { public static void RegisterConfiguration(i); // Now i cannot register second time public static object DoWork(i); Thread.Sleep(5000); // DoWork() may take a little while to complete before unregistered public static void UnregisterConfiguration(i); }

• Where can I find my iPhone app's Core Data persistent store?

  - by Dr Dork

  I'm diving into iPhone development, so I apologize in advance if this is a ridiculous question, but in a new iPad app project using the Core Data framework, here's the generated code for creating the persistentStoreCoordinator... - (NSPersistentStoreCoordinator *)persistentStoreCoordinator { if (persistentStoreCoordinator != nil) { return persistentStoreCoordinator; } NSURL *storeUrl = [NSURL fileURLWithPath: [[self applicationDocumentsDirectory] stringByAppendingPathComponent: @"ApplicationName.sqlite"]]; NSError *error = nil; persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:[self managedObjectModel]]; if (![persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeUrl options:nil error:&error]) { /* Replace this implementation with code to handle the error appropriately. abort() causes the application to generate a crash log and terminate. You should not use this function in a shipping application, although it may be useful during development. If it is not possible to recover from the error, display an alert panel that instructs the user to quit the application by pressing the Home button. Typical reasons for an error here include: * The persistent store is not accessible * The schema for the persistent store is incompatible with current managed object model Check the error message to determine what the actual problem was. */ NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } return persistentStoreCoordinator; } My questions are... The first time I run the app, is the ApplicationName.sqllite database created automatically if it doesn't exist? If not, when is it created? When data is added to it programmatically? Once the DB does exist, where can I locate the file? I'd like to open it with a different program so I can manually manipulate the data. Thanks so much in advance for your help! I'm going to continue researching these questions right now.

• how to format a date with code igniter

• Asp.Net 2 integrated sites How to Logout second site programatically.

  - by NBrowne

  Hi , I am working with an asp.net 2.0 site (call it site 1) which has an iframe in it which loads up another site (site2) which is also an asp.net site which is developed by our team. When you log onto site 1 then behind the scenes site 2 is also logged in so that when you click the iframe tab then this displays site 2 with the user logged in (to prevent the user from having to log in twice). The problem i have is that when a user logs out of site 1 then we call some cleanup methods to perform FormsAuthentication.SignOut and clean session variables etc but at the moment no cleanup is called when the user on site 2. So the issue is that if the user opens up Site 2 from within a browser then website 2 opens with the user still logged in which is undesired. Can anyone give me some guidance as to the best approach for this?? One possible approach i though of was just that on click of logout button i could do a call to a custom page on Site 2 which would do the logout. Code below HttpWebRequest request; request = ((HttpWebRequest)(WebRequest.Create("www.mywebsite.com/Site2Logout.aspx"))); request.Method = "POST"; HttpCookie cookie = HttpContext.Current.Request.Cookies[FormsAuthentication.FormsCookieName]; Cookie authenticationCookie = new Cookie( FormsAuthentication.FormsCookieName, cookie.Value, cookie.Path, HttpContext.Current.Request.Url.Authority); request .CookieContainer = new CookieContainer(); request .CookieContainer.Add(authenticationCookie); response.GetResponse(); Problem i am having with this code is that when i run it and debug on Site 2 and check to see if the user is Authenticated they are not which i dont understand because if i open browser and browse to Site 2 i am Still authenticated. Any ideas , different direction to take etc ??? Please let me know if you need any more info or if i something i have said dosent make sense. Thanks

• Serialization of Queue type not working

  - by Soham

  Consider this piece of code: private Queue Date=new Queue(); //other declarations public DateTime _Date { get { return (DateTime)Date.Peek();} set { Date.Enqueue(value); } } //other properties and stuff.... public void UpdatePosition(...) { //other code IFormatter formatter = new BinaryFormatter(); Stream Datestream = new MemoryStream(); formatter.Serialize(Datestream, Date); byte[] Datebin = new byte[2048]; Datestream.Read(Datebin,0,2048); //Debug-Bug Console.WriteLine(Convert.ToString(this._Date)); Console.WriteLine(BitConverter.ToString(Datebin, 0, 3)); //other code } The output of the first WriteLine is perfect. I.e to check if really the Queue is initialised or not. It is. The right variables are stored etc. (I inserted a value in that Queue, that part of the code is not shown.) But the second WriteLine is not giving the right expected answer: It serializes the entire Queue to 00-00-00.

• Using git svn with some awkward permissions

  - by Migs

  Due to some funky permissions on our client's side that we can't change, we have a project whose hierarchy looks something like: projectname/trunk: foo/, bar/, baz/ projectname/branches: branch1/, branch2/ (where branch1 and branch2 each contain foo, bar, and baz.) The thing is, I have no permission to access trunk, so I can't just do a clone of project/trunk. I do have permission to access branches. What I am currently doing is checking out each subdirectory individually via git svn clone, so that each one has their own git repo. I use a script to update/commit them all, but what I would prefer to do is to check them all out under a single repo, and be able to commit changes with a single call to git svn dcommit. Is this possible? I mentioned the branches hierarchy because if possible, I'd also like to be able to track the branches the way I could if the permissions were more sane. I've tried permuting a lot of options that sounded useful, but I haven't found one that gives me exactly what I want. I sense that the solution may have something to do with --no-minimize-url, but I'm not even sure about that, as it didn't help me when I tried it.

• Auto Submitting a form (cURL)

  - by cast01

  Im writing a form to post data off to paypal, and this works fine, i create the form with hidden fields and then have a submit button that submits everything to paypal. However, when the user clicks that button, there is more that i want to do, for example change their cart status in the database. So, i want to be able to execute some code when they click submit and then post the data to paypal. I dont want to use javascript for this. My method at the moment is using cURL, the form posts back to the current page, i then check for $_POST data, do my other commands like updating the status of the cart, and then create a curl command, and post the form data to paypal. Now, it gets posted successfully, but the browser doesnt go off to paypal. At first i was just retirieving the result in a string and then echoing it out and i could see that the post was successful, then i set CURLOPT_FOLLOWLOCATION to 1 assuming this would let the browser go off to paypal but it doesnt, what it seems to do is grab some stuff from paypal and put it on my page. Is using cURL the right thing for this? and if so, how do i get round this problem? I want to stay away from javascript for this as only users with javascript enabled would have their cart updated. The code im using for curl is below, the post_data is an array i created and then read key-value pairs into post_string. //Set cURL Options curl_setopt($curl_connection, CURLOPT_CONNECTTIMEOUT, 30); curl_setopt($curl_connection, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)"); curl_setopt($curl_connection, CURLOPT_RETURNTRANSFER, false); curl_setopt($curl_connection, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($curl_connection, CURLOPT_FOLLOWLOCATION, 1); curl_setopt($curl_connection, CURLOPT_MAXREDIRS, 20); //Set Data to be Posted curl_setopt($curl_connection, CURLOPT_POSTFIELDS, $post_string); //Execute Request curl_exec($curl_connection);

• How to Prevent PostBack Event Handler from Firing

  - by user331744

  I have a custom class (ServerSideValidator.vb) that validates user input on server side (it doesn't use any of the .NET built in validators, therefore Page.Validate() is not an option for me). I am calling the Validate() method on page.IsPostback event and the class performs without any problem My issue is, when validation fails (returns false), I want to stop the postback event handler from firing, but load the page along with all the controls and user-input values in them. If I do, Response.End(), the page comes up blank. I can programmatically instruct the page to go to the previous page (original form before postback), but it loses all user-inputs. I thought of creating a global boolean variable in the page code behind file and check the value before performing any postback method, but this approach takes away from my plan to provide all functionalities inside the class itself. The page object is being referenced to ServerSideValidator. Seems like all the postback related properties/variables I come across inside Page class are 'Readonly' and I can't assign value(s) to control/prevent postback event from firing. Any idiea on how I can accomplish this? Please let me know if you need further details

• I cannot make log4net work in my web application :(

  - by vtortola

  Hi, I'm trying to set up log4net but I cannot make it work. I've put this in my Web.config: <configSections> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" /> <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender"> <file value="logfile.log" /> <appendToFile value="true" /> <rollingStyle value="Composite" /> <maxSizeRollBackups value="14" /> <maximumFileSize value="15000KB" /> <datePattern value="yyyyMMdd" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" /> </layout> </appender> <root> <level value="DEBUG" /> <appender-ref ref="RollingFileAppender" /> <appender-ref ref="TraceAppender" /> </root> (StackOverflow is not rendering correctly the code I've pasted, I don't know why) Then, in my code I execute: log4net.Config.XmlConfigurator.Configure(new FileInfo(HttpContext.Current.Server.MapPath("~/Web.config"))); ILog log = LogManager.GetLogger("MainLogger"); if(log.IsDebugEnabled) log.Debug("lalala"); But nothing happen. I check the "log" variable, and contains an LogImpl object, that has all the logging levels enabled. I get no error or configuration warning, I cannot see any file in the root, in the bin or anywhere. What do I have to do to make it work? Cheers.

• Arduino variable going blank after first pass.

  - by user541597

  I have an arduino sketch that takes a timet and when that timet is equal to the current time it sets the new timet to timet + 2. For example: char* convert(char* x, String y){ int hour; int minute; sscanf(x, "%d:%d", &hour, &minute); char buf[6]; if (y == "6"){ if (hour > 17){ hour = (hour+6)%24; snprintf(buf, 10, "%d:%d", hour, minute ); }else if (hour < 18){ //hour = hour + 6; minute = (minute + 2); snprintf(buf, 10, "%d:%d", hour, minute); } } if (y == "12"){ if (hour > 11){ hour = (hour+12)%24; snprintf(buf, 10, "%d:%d", hour, minute ); } else if (hour < 12){ hour = hour + 12; snprintf(buf, 10, "%d:%d", hour, minute); } } if (y == "24"){ hour = (hour+24)%24; snprintf(buf, 10, "%d:%d", hour, minute ); } return buf; } sketch starts for example at 1:00am timet is set to 1:02, at system time 1:02 timet == system time my loops looks like this: if (timet == currenttime){ timet = convert(timet) } From this now when ever I check the value of timet it should equal 1:04, however I am getting the correct value at the first run after the execution of convert however everytime after that my timet value is blank. I tried changing the code instead of using the if loop I only run the convert function when I send for example t through the serial monitor, this works fine and outputs the correct timet after the execution of the convert function, So I figured the problem is in the if loop... Any ideas?

• how to change type of value in an php array and sorting it..is it possible ?

  - by justjoe

  hi, i got problem with my code and hopefully someone able to figure it out. The main purpose is to sort array based on its value (then reindex its numerical key). i got this sample of filename : $filename = array("index 198.php", "index 192.php", "index 144.php", "index 2.php", "index 1.php", "index 100.php", "index 111.php"); $alloutput = array(); //all of index in array foreach ($filename as $name) { preg_match('#(\d+)#', $name, $output); // take only the numerical from file name array_shift($output); // cleaned. the last code create duplicate numerical in $output, if (is_array($hasilku)) { $alloutput = array_merge($alloutput, $output); } } //try to check the type of every value in array foreach ($alloutput as $output) { if (is_array($hasil)) { echo "array true </br>"; } elseif (is_int($hasil)) { echo "integer true </br>"; } elseif (is_string($hasil)) { //the numerical taken from filename always resuld "string". echo "string true </br>"; } } the output of this code will be : Array ( [0] = 198 [1] = 192 [2] = 144 [3] = 2 [4] = 1 [5] = 100 [6] = 111 ) i have test every output in array. It's all string (and not numerical), So the question is how to change this string to integer, so i can sort it from the lowest into the highest number ? the main purpose of this code is how to output array where it had been sort from lowest to highest ?

• Best way of showing more results with javascript/css

  - by Ricardo Neves

  I'm developing a website and i'm having troubles showing the search results to the user the way I want. Basically, after the user search, the page makes a couple of ajax requests and as soon as a response arrive it appends the info to a specific element on my page. Each results is shown as a line... The problem is that in most case there are going to be more than 1000 results and this would make the page have a large scroll. My idea was to show only the first 15 results and when the user clicks "show more" the element would expand and show the next 15 results and so on... This would be easier to do if the website wasn't responsive, but because it is I can't find the proper way of implementing what I want without lowering the website perfomance. I have "2 ideas": The first is by using something like #element .div:nth-child(-n+15) on my css and figure a way of changing the "15" to how much results I want to show... I don't know if this can be done. Is it possible to call css rules with parameters? Maybe with less css? The second option is probably a bad option if i don't want to lower the website performance. Using javascript I would check if there is a specific css class(like .show-15 .show30 .show45) and add that class to my element and if it don't exist, create it somehow.. Any help would be appreciated.

• linked list sort function only loops once

  - by Tristan Pearce

  i have a singly linked list that i am trying to sort from least to greatest by price. here is what i have so far struct part { char* name; float price; int quantity; struct part *next; }; typedef struct part partType; partType *sort_price(partType **item) { partType *temp1 = *item; partType *temp2 = (*item)->next; if ( *item == NULL || (*item)->next == NULL ) return *item; else { while ( temp2 != NULL && temp2->next != NULL ){ if (temp2->price > temp2->next->price){ temp1->next = temp2->next; temp2->next = temp2->next->next; temp1->next->next = temp2; } temp1 = temp2; temp2 = temp2->next; } } return *item; } the list is already populated but when i call the sort function it only swaps the first two nodes that satisfy the condition in the if statement. I dont understand why it doesnt do the check again after the two temp pointers are incremented.

• How to store visited states in iterative deepening / depth limited search?

  - by colinfang

  Update: Search for the first solution. for a normal Depth First Search it is simple, just use a hashset bool DFS (currentState) = { if (myHashSet.Contains(currentState)) { return; } else { myHashSet.Add(currentState); } if (IsSolution(currentState) return true; else { for (var nextState in GetNextStates(currentState)) if (DFS(nextState)) return true; } return false; } However, when it becomes depth limited, i cannot simply do this bool DFS (currentState, maxDepth) = { if (maxDepth = 0) return false; if (myHashSet.Contains(currentState)) { return; } else { myHashSet.Add(currentState); } if (IsSolution(currentState) return true; else { for (var nextState in GetNextStates(currentState)) if (DFS(nextState, maxDepth - 1)) return true; } return false; } Because then it is not going to do a complete search (in a sense of always be able to find a solution if there is any) before maxdepth How should I fix it? Would it add more space complexity to the algorithm? Or it just doesn't require to memoize the state at all. Update: for example, a decision tree is the following: A - B - C - D - E - A | F - G (Goal) Starting from state A. and G is a goal state. Clearly there is a solution under depth 3. However, using my implementation under depth 4, if the direction of search happens to be A(0) -> B(1) -> C(2) -> D(3) -> E(4) -> F(5) exceeds depth, then it would do back track to A, however E is visited, it would ignore the check direction A - E - F - G

• Best way to sign data in web form with user certificate

  - by salgiza

  We have a C# web app where users will connect using a digital certificate stored in their browsers. From the examples that we have seen, verifying their identity will be easy once we enable SSL, as we can access the fields in the certificate, using Request.ClientCertificate, to check the user's name. We have also been requested, however, to sign the data sent by the user (a few simple fields and a binary file) so that we can prove, without doubt, which user entered each record in our database. Our first thought was creating a small text signature including the fields (and, if possible, the md5 of the file) and encrypt it with the private key of the certificate, but... As far as I know we can't access the private key of the certificate to sign the data, and I don't know if there is any way to sign the fields in the browser, or we have no other option than using a Java applet. And if it's the latter, how we would do it (Is there any open source applet we can use? Would it be better if we create one ourselves?) Of course, it would be better if there was any way to "sign" the fields received in the server, using the data that we can access from the user's certificate. But if not, any info on the best way to solve the problem would be appreciated.

• How to rewrite data-driven test suites of JUnit 3 in Junit 4?

  - by rics

  I am using data-driven test suites running JUnit 3 based on Rainsberger's JUnit Recipes. The purpose of these tests is to check whether a certain function is properly implemented related to a set of input-output pairs. Here is the definition of the test suite: public static Test suite() throws Exception { TestSuite suite = new TestSuite(); Calendar calendar = GregorianCalendar.getInstance(); calendar.set(2009, 8, 05, 13, 23); // 2009. 09. 05. 13:23 java.sql.Date date = new java.sql.Date(calendar.getTime().getTime()); suite.addTest(new DateFormatTestToString(date, JtDateFormat.FormatType.YYYY_MON_DD, "2009-SEP-05")); suite.addTest(new DateFormatTestToString(date, JtDateFormat.FormatType.DD_MON_YYYY, "05/SEP/2009")); return suite; } and the definition of the testing class: public class DateFormatTestToString extends TestCase { private java.sql.Date date; private JtDateFormat.FormatType dateFormat; private String expectedStringFormat; public DateFormatTestToString(java.sql.Date date, JtDateFormat.FormatType dateFormat, String expectedStringFormat) { super("testGetString"); this.date = date; this.dateFormat = dateFormat; this.expectedStringFormat = expectedStringFormat; } public void testGetString() { String result = JtDateFormat.getString(date, dateFormat); assertTrue( expectedStringFormat.equalsIgnoreCase(result)); } } How is it possible to test several input-output parameters of a method using JUnit 4? This question and the answers explained to me the distinction between JUnit 3 and 4 in this regard. This question and the answers describe the way to create test suite for a set of class but not for a method with a set of different parameters.

• HTML input not working correctly with AJAX update panels used else where on page

  - by Sean P

  I have some update panels on my page that do some asyncpostbacks to keep some dropdownlists correctly populated. My problem is that on my page i have an HTML input that is handling some file uploads. With the AJAX on the page with asyncpostbacks, and while i step through my code behind, the files arent being uploaded. Using a postbacktrigger (non-async) is not possible because of my layout. Here is my code: <div id="divFileInputs" runat="server"> <input id="file1" name="fileInput" type="file" runat="server" size="50" style="width: 50em" onfocus="AddFileInput()" class="textbox" /></div> <select id="selectFileList" name="ListBox1" size="5" style="width: 50em; text-align: left;" class="textbox" /> <input id="RemoveAttachmentButton" type="button" value="Remove" onclick="RemoveFileInput()" class="removebutton " /> </div> Here is my code behind: Protected Sub CopyAttachments(ByVal issueId As String) Dim files As HttpFileCollection = Request.Files Dim myStream As System.IO.Stream Dim service As New SubmitService.Service For i As Integer = 0 To files.Count - 1 Dim postedFile As HttpPostedFile = files(i) Dim fileNameWithoutPath As String = System.IO.Path.GetFileName(postedFile.FileName) If fileNameWithoutPath.Length > 0 And issueId.Length > 0 Then Dim fileLength As Integer = postedFile.ContentLength Dim fileContents(fileLength) As Byte ' Read the file into the byte array. Send it to the web service. myStream = postedFile.InputStream myStream.Read(fileContents, 0, fileLength) service.ClearQuestAttachToIssue(issueId, fileNameWithoutPath, fileContents) End If Next service = Nothing End Sub When I put a breakpoint in at the declaration of service and then check the value of "files", the count is 0. I am expecting it to be 2 when i have one file uploaded. Anyone know how to fix this?

• Sql Server 2005 Database Tables - Row Comparison Column By Column.

  - by Goober

  Scenario I have an TWO datbase tables of exactly the SAME STRUCTURE. The difference between these tables is that one contains data populated by one application and the other is populated by a different application. Each application is trying to produce the same result, but using two different methods of implementation. Proposed Idea What I want to do, is run both applications, which will roughly produce 35000 rows containing 10 columns each - So all in all, 70000 rows of data, I then want to compare each row of data, COLUMN BY COLUMN to check whether the values are the same or not. Current Thoughts Since there is so much data to compare, I feel that the best way in which to do this would be to write an application, preferably in C# (but if necessary, T-sql), to compare each row of data column by column, and write out any failed comparisons to a text log file. Question Could anybody suggest an efficient way in which to perform column by column row comparison for 70000 rows worth of data? I'm struggling for ideas on how to tackle this problem. Extra Detail The two applications are both written in C# .Net 3.5. The Database is running on Sql Server 2005. Help greatly appreciated.

• Best way to use Google's hosted jQuery, but fall back to my hosted library on Google fail

  - by Nosredna

  What would be a good way to attempt to load the hosted jQuery at Google (or other Google hosted libs), but load my copy of jQuery if the Google attempt fails? I'm not saying Google is flaky. There are cases where the Google copy is blocked (apparently in Iran, for instance). Would I set up a timer and check for the jQuery object? What would be the danger of both copies coming through? Not really looking for answers like "just use the Google one" or "just use your own." I understand those arguments. I also understand that the user is likely to have the Google version cached. I'm thinking about fallbacks for the cloud in general. Edit: This part added... Since Google suggests using google.load to load the ajax libraries, and it performs a callback when done, I'm wondering if that's the key to serializing this problem. I know it sounds a bit crazy. I'm just trying to figure out if it can be done in a reliable way or not. Update: jQuery now hosted on Microsoft's CDN. http://www.asp.net/ajax/cdn/
