    - by ofer shwartz
    HI! I'm trying to create a list that some of the elements are defined and some are not, without priority to order.

  • After rich:extendedDataTable sortby, other actions are not getting executed

    - by kksachin
    I have several tabs and one of the tabs uses rich:extendedDataTable. If sortBy is clicked in the page where table is used and if I navigate to another page, it looks for the bean of the old page and throws an error saying that sortyBy of the column is undefined. E.g. If I use sortBy on userId in tab1 (where the column must have sortBy="#{data.userId}") and then I click on tab2, it looks for the data.userId and throws an error. I am using Richfaces version 3.2.2SR1. Can anyone help me on this? Here is the complete trace: javax.el.PropertyNotFoundException: /amendapplication/historyDetails.xhtml @33,174 sortBy="#{data.statusChangeTime}": Property 'statusChangeTime' not found on type uk.gov.wales.rpd.domain.applicationmanagement.ApplicationAttributeEntity com.sun.facelets.el.TagValueExpression.getValue(TagValueExpression.java:73) org.richfaces.model.impl.expressive.ValueBindingExpression.evaluate(ValueBindingExpression.java:59) org.richfaces.model.impl.expressive.ObjectWrapperFactory.wrapObject(ObjectWrapperFactory.java:189) org.richfaces.model.ModifiableModel$RowKeyWrapperFactory.wrapObject(ModifiableModel.java:57) org.richfaces.model.impl.expressive.ObjectWrapperFactory$2.convert(ObjectWrapperFactory.java:177) org.richfaces.model.impl.expressive.ObjectWrapperFactory.convertList(ObjectWrapperFactory.java:138) org.richfaces.model.impl.expressive.ObjectWrapperFactory.wrapList(ObjectWrapperFactory.java:175) org.richfaces.model.ModifiableModel.sort(ModifiableModel.java:235) org.richfaces.model.ModifiableModel.modify(ModifiableModel.java:206) org.richfaces.component.UIExtendedDataTable.createDataModel(UIExtendedDataTable.java:310) org.ajax4jsf.component.UIDataAdaptor.getExtendedDataModel(UIDataAdaptor.java:621) org.ajax4jsf.component.UIDataAdaptor.setRowKey(UIDataAdaptor.java:339) org.ajax4jsf.component.UIDataAdaptor.iterate(UIDataAdaptor.java:1034) org.ajax4jsf.component.UIDataAdaptor.processDecodes(UIDataAdaptor.java:1158) org.ajax4jsf.component.UIDataAdaptor.processDecodes(UIDataAdaptor.java:1168) javax.faces.component.UIForm.processDecodes(UIForm.java:209) org.ajax4jsf.component.AjaxViewRoot$1.invokeContextCallback(AjaxViewRoot.java:392) org.ajax4jsf.component.AjaxViewRoot.processPhase(AjaxViewRoot.java:238) org.ajax4jsf.component.AjaxViewRoot.processDecodes(AjaxViewRoot.java:409) com.sun.faces.lifecycle.ApplyRequestValuesPhase.execute(ApplyRequestValuesPhase.java:78) com.sun.faces.lifecycle.Phase.doPhase(Phase.java:100) com.sun.faces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:118) javax.faces.webapp.FacesServlet.service(FacesServlet.java:265) org.apache.myfaces.webapp.filter.ExtensionsFilter.doFilter(ExtensionsFilter.java:341) org.ajax4jsf.webapp.BaseXMLFilter.doXmlFilter(BaseXMLFilter.java:177) org.ajax4jsf.webapp.BaseFilter.handleRequest(BaseFilter.java:267) org.ajax4jsf.webapp.BaseFilter.processUploadsAndHandleRequest(BaseFilter.java:380) org.ajax4jsf.webapp.BaseFilter.doFilter(BaseFilter.java:507) org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96)

  • multithreading issue

    - by vbNewbie
    I have written a multithreaded crawler and the process is simply creating threads and having them access a list of urls to crawl. They then access the urls and parse the html content. All this seems to work fine. Now when I need to write to tables in a database is when I experience issues. I have 2 declared arraylists that will contain the content each thread parse. The first arraylist is simply the rss feed links and the other arraylist contains the different posts. I then use a for each loop to iterate one while sequentially incrementing the other and writing to the database. My problem is that each time a new thread accesses one of the lists the content is changed and this affects the iteration. I tried using nested loops but it did not work before and this works fine using a single thread.I hope this makes sense. Here is my code: SyncLock dlock For Each l As String In links finallinks.Add(l) Next End SyncLock SyncLock dlock For Each p As String In posts finalposts.Add(p) Next End SyncLock ... Dim i As Integer = 0 SyncLock dlock For Each rsslink As String In finallinks postlink = finalposts.Item(i) i = i + 1 finallinks and finalposts are the two arraylists. I did not include the rest of the code which shows the threads working but this is the essential part where my error occurs which is basically here postlink = finalposts.Item(i) i = i + 1 ERROR: index was out of range. Must be non-negative and less than the size of the collection Is there an alternative?

  • What are the hibernate annotations used to persist a value typed Map with an enumerated type as a ke

    - by Jason Novak
    I am having trouble getting the right hibernate annotations to use on a value typed Map with an enumerated class as a key. Here is a simplified (and extremely contrived) example. public class Thing { public String id; public Letter startLetter; public Map<Letter,Double> letterCounts = new HashMap<Letter, Double>(); } public enum Letter { A, B, C, D } Here are my current annotations on Thing @Entity public class Thing { @Id public String id; @Enumerated(EnumType.STRING) public Letter startLetter; @CollectionOfElements @JoinTable(name = "Thing_letterFrequencies", joinColumns = @JoinColumn(name = "thingId")) @MapKey(columns = @Column(name = "letter", nullable = false)) @Column(name = "count") public Map<Letter,Double> letterCounts = new HashMap<Letter, Double>(); } Hibernate generates the following DDL to create the tables for my MySql database create table Thing (id varchar(255) not null, startLetter varchar(255), primary key (id)) type=InnoDB; create table Thing_letterFrequencies (thingId varchar(255) not null, count double precision, letter tinyblob not null, primary key (thingId, letter)) type=InnoDB; Notice that hibernate tries to define letter (my map key) as a tinyblob, however it defines startLetter as a varchar(255) even though both are of the enumerated type Letter. When I try to create the tables I see the following error BLOB/TEXT column 'letter' used in key specification without a key length I googled this error and it appears that MySql has issues when you try to make a tinyblob column part of a primary key, which is what hibernate needs to do with the Thing_letterFrequencies table. So I would rather have letter mapped to a varchar(255) the way startLetter is. Unfortunately, I've been fussing with the MapKey annotation for a while now and haven't been able to make this work. I've also tried @MapKeyManyToMany(targetEntity=Product.class) without success. Can anyone tell me what are the correct annotations for my letterCounts map so that hibernate will treat the letterCounts map key the same way it does startLetter?

  • Pointers in C# to make int array?

    - by Joshua
    The following C++ program compiles and runs as expected: #include <stdio.h> int main(int argc, char* argv[]) { int* test = new int[10]; for (int i = 0; i < 10; i++) test[i] = i * 10; printf("%d \n", test[5]); // 50 printf("%d \n", 5[test]); // 50 return getchar(); } The closest C# simple example I could make for this question is: using System; class Program { unsafe static int Main(string[] args) { // error CS0029: Cannot implicitly convert type 'int[]' to 'int*' int* test = new int[10]; for (int i = 0; i < 10; i++) test[i] = i * 10; Console.WriteLine(test[5]); // 50 Console.WriteLine(5[test]); // Error return (int)Console.ReadKey().Key; } } So how do I make the pointer?

  • Java MySQL Query Problem MySQLSyntaxErrorException When Creating a Table

    - by Aqib Mushtaq
    I fairly new to MySQL with Java, but I have executed a few successful INSERT queries however cannot seem to get the CREATE TABLE query to execute without getting the 'MySQLSyntaxErrorException' exception. My code is as follows: import java.sql.*; Statement stmt; Class.forName("com.mysql.jdbc.Driver"); String url = "jdbc:mysql://localhost:3306/mysql"; Connection con = DriverManager.getConnection(url, "root", "password"); stmt = con.createStatement(); String tblSQL = "CREATE TABLE IF NOT EXISTS \'dev\'.\'testTable\' (\n" + " \'id\' int(11) NOT NULL AUTO_INCREMENT,\n" + " \'date\' smallint(6) NOT NULL\n" + ") ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;"; stmt.executeUpdate(tblSQL); stmt.close(); con.close(); And the error is as follows: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''dev'.'testTable' ( 'id' int(11) NOT NULL AUTO_INCREMENT, 'date' smallint(6) N' at line 1 I would appreciate it if anyone could spot the mistake in this query, as I've tried executing this within phpMyAdmin and it works as it should. Thanks in advance.

  • Recursively MySQL Query

    How can I implement recursive MySQL Queries. I am trying to look for it but resources are not very helpful.

  • Javascript permission denied - different port

    - by Grnbeagle
    Hi, I have a rails app running on port 3000. The page in question has an iframe and I need to resize it depending on the height of the content loaded in the iframe. <iframe id="ifrm_col3" name="ifrm_col3" frameborder="0" src="<%=invite_path(@invite.alias)%>" onload="util.resize_iframe('ifrm_col3');"></iframe> The resize function is here: util.resize_iframe = function(frame_id) { var h = document.getElementById(frame_id).contentWindow.document.body.scrollHeight; document.getElementById(frame_id).height = h; } After the iframe loads, I see this error in FireBug: Error: Permission denied for <http://192.168.0.157> to get property Window.document from <http://192.168.0.157:3000>. Source File: http://192.168.0.157:3000/javascripts/application.js?1268327481 Line: 84 The src of iframe is a relative path, but I'm not sure why the port info from the parent page is not retained. Is there any workaround to this problem? I tried creating a function in the parent page and calling it from the iframe, but ran into the same issue. Due to extra features in the site, I need to stick to port 3000 for the rails app. Any suggestion is appreciated.

  • Enabling/Disabling Aero from a Windows Service

    - by rgould
    I have some code to enable/disable the Windows Aero service in Vista, and I would like to run it in a Windows Service. The code works in a standalone application, but when I run it from a Service, nothing happens. No errors or exceptions are thrown. I realise that running code in a service is a different scope than running code in an application, but in this case, how would I enable/disable Aero from the service? Is this even possible? Here is the code I am working with: public static readonly uint DWM_EC_DISABLECOMPOSITION = 0; public static readonly uint DWM_EC_ENABLECOMPOSITION = 1; [DllImport("dwmapi.dll", EntryPoint="DwmEnableComposition")] protected static extern uint Win32DwmEnableComposition(uint uCompositionAction); public static bool EnableAero() { Win32DwmEnableComposition(DWM_EC_ENABLECOMPOSITION); } Edit: It turns out that the DwmEnableComposition call is returning HRESULT 0x80070018, or ERROR_BAD_LENGTH. Seems like a strange error, since the code works when not running as a service. I also tried changing the entire thing to the following code, but got the same result. It sets the window station and desktop, and it seems to be correct, but the call to DwmEnableComposition results in the same error. I've not included the PInvoke declarations for brevity. protected override void OnStop() { IntPtr winStation = OpenWindowStation("winsta0", true, 0x10000000 /* GENERIC_ALL */); if (winStation == null || winStation.ToInt32() == 0) { String err = new Win32Exception(Marshal.GetLastWin32Error()).Message; } if (!SetProcessWindowStation(winStation)) { String err = new Win32Exception(Marshal.GetLastWin32Error()).Message; } uint thread = GetCurrentThreadId(); IntPtr hdesk = OpenInputDesktop(0, false, 0x10000000 /* GENERIC_ALL */); if (hdesk == null || hdesk.ToInt32() == 0) { String err = new Win32Exception(Marshal.GetLastWin32Error()).Message; } if (!SetThreadDesktop(hdesk)) { String err = new Win32Exception(Marshal.GetLastWin32Error()).Message; } uint result = Win32DwmEnableComposition(DWM_EC_DISABLECOMPOSITION); if (result != 0) { String err = new Win32Exception(Marshal.GetLastWin32Error()).Message; } }

  • initialising a 2-dim Array in Scala

    - by Stefan W.
    (Scala 2.7.7:) I don't get used to 2d-Arrays. Arrays are mutable, but how do I specify a 2d-Array which is - let's say of size 3x4. The dimension (2D) is fixed, but the size per dimension shall be initializable. I tried this: class Field (val rows: Int, val cols: Int, sc: java.util.Scanner) { var field = new Array [Char](rows)(cols) for (r <- (1 to rows)) { val line = sc.nextLine () val spl = line.split (" ") field (r) = spl.map (_.charAt (0)) } def put (val rows: Int, val cols: Int, c: Char) = todo () } I get this error: :11: error: value update is not a member of Char field (r) = spl.map (_.charAt (0)) If it would be Java, it would be much more code, but I would know how to do it, so I show what I mean: public class Field { private char[][] field; public Field (int rows, int cols, java.util.Scanner sc) { field = new char [rows][cols]; for (int r = 0; r < rows; ++r) { String line = sc.nextLine (); String[] spl = line.split (" "); for (int c = 0; c < cols; ++c) field [r][c] = spl[c].charAt (0); } } public static void main (String args[]) { new Field (3, 4, new java.util.Scanner ("fraese.fld")); } } and fraese.fld would look, for example, like that: M M M M . M I get some steps wide with val field = new Array Array [Char] but how would I then implement 'put'? Or is there a better way to implement the 2D-Array. Yes, I could use a one-dim-Array, and work with put (y, x, c) = field (y * width + x) = c but I would prefer a notation which looks more 2d-ish.

  • ajax to php to curl and back..

    - by pfunc
    I am trying to make an ajax call to a php script. The php script calls an rss feed using curl, gets the data, and returns the data to the funciton. I keep getting an error "Warning: Wrong parameter count for curl_error() in" .... Here is my php code:1 $ch = curl_init() or die(curl_error()); curl_setopt($ch, CURLOPT_URL, $feed); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $data1 = curl_exec($ch) or die(curl_error()); echo $data1; and the ajax call: $.ajax({ url: "getSingleFeed.php", type: "POST", data: "feedURL=" + window.feedURL, success: function(feed){ alert(feed); }}); I tested all the variables, they are being passed correctly, I can echo them out. But this line: $data1 = curl_exec($ch) or die(curl_error()); is what is giving me the error. I am doing the same thing with curl on other pages, just without ajax, and it is working fine. Is there anything special I need to do with ajax to do this?

  • Multiple queries using same datacontext throws SqlException

    - by Raj
    I've search control with which I'm trying to implement search as user types something. I'm using Linq to SQL to fire queries against the database. Though it works fine usually, when user types the queries really fast some random SqlException is thrown.

Invalid attempt to call Read when reader is closed.

  • Is it possible to use SqlGeography with Linq to Sql?

    - by cofiem
    I've been having quite a few problems trying to use Microsoft.SqlServer.Types.SqlGeography. I know full well that support for this in Ling to Sql is not great. I've tried numerous ways, beginning with what would the expected way (Database type of geography, CLR type of SqlGeography). This produces the NotSupportedException, which is widely discussed via blogs. I've then gone down the path of treating the geography column as a varbinary(max), as geography is a UDT stored as binary. This seems to work fine (with some binary reading and writing extension methods). However, I'm now running into a rather obscure issue, which does not seem to have happened to many other people. System.InvalidCastException: Unable to cast object of type 'Microsoft.SqlServer.Types.SqlGeography' to type 'System.Byte[]'. This error is thrown from an ObjectMaterializer when iterating through a query. It seems to only occur when the tables containing geography columns are included in a query implicitly (ie. using the EntityRef<> properties to do joins). System.Data.Linq.SqlClient.ObjectReaderCompiler.ObjectReader`2.MoveNext() My question: If I'm retrieving the geography column as varbinary(max), I might expect the reverse error: can't cast byte[] to SqlGeography. That I would understand. This I don't. I do have some properies on the partial LINQ to SQL classes that hide the binary conversion... could those be the issue? Any help appreciated, and I know there's probably not enough information.

  • Session cookie not being created in Rails, very rarely and frustratingly.

    - by James
    Hi everyone, This is an issue sporadically for very few users, however we haven't been able to replicate it. However I have now got a Chrome instance (Mac) which is reproducing the error (for some unknown reason), and I hope to not restart it until I have this nailed! Rails application, using memcached for session store. While the bug manifests in the _app_session_id cookie not being created, our javascript-generated cookie test and app-generated language cookies are being created successfully. This means that 422 / InvalidAuthToken errors are thrown for every form that is submitted by those afflicted - people can't log into the app. The error occurs across all browsers - had reports for IE7 and Firefox (which most users use). Switching to another browser often fixes the issue (though not always), and standard cache-cookie-clear tactics do not. So now that I have got Chrome open which is having the same issue - in development, staging and live environments (meaning http and https). All other browsers are fine. I've restarted the servers and restarted memcached. I don't really want to restart Chrome - in the risk that the issue does go away with that (having said that, it hasn't worked for users). I've been tcpdumping the requests - and although I'll keep digging, I'd love it if anyone had any suggestions, places to start looking, anything. This is really painful ;) Thanks!

  • Using Sub-Types And Return Types in Scala to Process a Generic Object Into a Specific One

    - by pr1001
    I think this is about covariance but I'm weak on the topic... I have a generic Event class used for things like database persistance, let's say like this: class Event( subject: Long, verb: String, directobject: Option[Long], indirectobject: Option[Long], timestamp: Long) { def getSubject = subject def getVerb = verb def getDirectObject = directobject def getIndirectObject = indirectobject def getTimestamp = timestamp } However, I have lots of different event verbs and I want to use pattern matching and such with these different event types, so I will create some corresponding case classes: trait EventCC case class Login(user: Long, timestamp: Long) extends EventCC case class Follow( follower: Long, followee: Long, timestamp: Long ) extends EventCC Now, the question is, how can I easily convert generic Events to the specific case classes. This is my first stab at it: def event2CC[T <: EventCC](event: Event): T = event.getVerb match { case "login" => Login(event.getSubject, event.getTimestamp) case "follow" => Follow( event.getSubject, event.getDirectObject.getOrElse(0), event.getTimestamp ) // ... } Unfortunately, this is wrong. <console>:11: error: type mismatch; found : Login required: T case "login" => Login(event.getSubject, event.getTimestamp) ^ <console>:12: error: type mismatch; found : Follow required: T case "follow" => Follow(event.getSubject, event.getDirectObject.getOrElse(0), event.getTimestamp) Could someone with greater type-fu than me explain if, 1) if what I want to do is possible (or reasonable, for that matter), and 2) if so, how to fix event2CC. Thanks!

  • Problem accessing variable in a nested form partial

    - by brad
    I have a nested form in a rails view that is called like this <% f.fields_for :invoice_item_numbers do |item_no_form| %> <%= render 'invoice_item_number', :f => item_no_form %> <% end %> and the partial (_invoice_item_number.html.erb) looks like this <div class='invoice_item_numbers'> <% if f.object.new_record? %> <li><%= f.label :item_number %><%= f.text_field :item_number %> <%= link_to_function "remove", "$(this).parent().remove()", :class => 'remove_link' %></li> <% else %> <li class="inline"><%= f.label :item_number %><%= f.text_field :item_number %> </li><li class="inline"><%= f.label :description %><%= invoice_item_number.description %></li><li><%= f.label :amount %><%= f.text_field :amount %> <%= f.check_box '_destroy', :class => 'remove_checkbox' %> <%= f.label '_destroy', 'remove', :class => 'remove_label' %></li> <% end %> </div> This fails with the error message undefined method `description' for nil:NilClass Why does invoice_item_number return a nil object in this partial? It is obviously being defined somehow because if I change it to something else (e.g. item_number.description then the error message becomes undefined local variable or methoditem_number' for #instead. The invoice_item_number object that is being displayed by this partial is being used perfectly well by the form helpers as<%= f.text_field :item_number %and<% f.text_field :amount %both work perfectly well. I have tried a number of solutions such as using@invoice_item_number` and explicitly defining an object in the render method but these have not worked. Presumably there is a very simple answer to this.

  • Foreign key not working in MySQL: Why can I INSERT a value that's not in the foreign column?

    - by stalepretzel
    I've created a table in MySQL: CREATE TABLE actions ( A_id int NOT NULL AUTO_INCREMENT, type ENUM('rate','report','submit','edit','delete') NOT NULL, Q_id int NOT NULL, U_id int NOT NULL, date DATE NOT NULL, time TIME NOT NULL, rate tinyint(1), PRIMARY KEY (A_id), CONSTRAINT fk_Question FOREIGN KEY (Q_id) REFERENCES questions(P_id), CONSTRAINT fk_User FOREIGN KEY (U_id) REFERENCES users(P_id)); This created the table I wanted just fine (although a "DESCRIBE actions;" command showed me that the foreign keys were keys of type MUL, and I'm not sure what this means). However, when I try to enter a Q_id or a U_id that does not exist in the questions or users tables, MySQL still allows these values. What did I do wrong? How can I prevent a table with a foreign key from accepting invalid data? If I add TYPE=InnoDB to the end, I get an error: ERROR 1005 (HY000): Can't create table './quotes/actions.frm' (errno: 150) Why might that happen? I'm told that it's important to enforce data integrity with functional foreign keys, but also that InnoDB should not be used with MySQL. What do you recommend?

  • Django caching seems to be causing problems

    - by Issy
    Hey guys, i have just implemented the Django Cache Local Memory back end in some my code, however it seems to be causing a problem. I get the following error when trying to view the site (With Debug On): Traceback (most recent call last): File "/usr/lib/python2.6/dist-packages/django/core/servers/basehttp.py", line 279, in run self.result = application(self.environ, self.start_response) File "/usr/lib/python2.6/dist-packages/django/core/servers/basehttp.py", line 651, in __call__ return self.application(environ, start_response) File "/usr/lib/python2.6/dist-packages/django/core/handlers/wsgi.py", line 245, in __call__ response = middleware_method(request, response) File "/usr/lib/python2.6/dist-packages/django/middleware/cache.py", line 91, in process_response patch_response_headers(response, timeout) File "/usr/lib/python2.6/dist-packages/django/utils/cache.py", line 112, in patch_response_headers response['Expires'] = http_date(time.time() + cache_timeout) TypeError: unsupported operand type(s) for +: 'float' and 'str' I have checked my code, for caching everything seems to be ok. For example, i have the following in my middleware. MIDDLEWARE_CLASSES = ( 'django.contrib.sessions.middleware.SessionMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.middleware.cache.UpdateCacheMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.cache.FetchFromCacheMiddleware', 'django.contrib.flatpages.middleware.FlatpageFallbackMiddleware', ) My settings for Cache: CACHE_BACKEND = 'locmem://' CACHE_MIDDLEWARE_SECONDS = '3600' CACHE_MIDDLEWARE_KEY_PREFIX = 'za' CACHE_MIDDLEWARE_ANONYMOUS_ONLY = True And some of my code (template tag): def get_featured_images(): """ provides featured images """ cache_key = 'featured_images' images = cache.get(cache_key) if images is None: images = FeaturedImage.objects.all().filter(enabled=True)[:5] cache.set(cache_key, images) return {'images': images} Any idea what could be the problem, from the error message below it looks like there's an issue in django's cache.py?

  • GCC Dynamic library building problem

    - by Sirish Kumar
    I am new to linux, while compiling with dynamic library I am getting the segmentationfault error. I have two files ctest1.c void ctest1(int *i) { *i =10; } ctest2.c void ctest2(int *i) { *i =20; } I have compiled both files to a shared library named libtest.so using following command gcc -shared -W1,-soname,libtest.so.1 -o libtest.so.1.0.1 ctest1.o ctest2.o -lc And I have wrote another program prog.c which uses functions exported by this library prog.c #include void (ctest1)(int); void (ctest2)(int*); int main() { int a; ctest1(&a); printf("%d",a); return 0; } And when I have built the executable with following command gcc -Wall prog.c -L. -o prog But when I run the generated executable I get the SegmentationFault error. When I checked the header of prog with ldd it shows linux-vdso.so.1 = (0x00007f99dff000) libc.so.6 = /lib64/libc.so.6 (0x0007feeaa8c1000) /lib64/ld-linux-x86-64.so.2 (0x00007feeaac1c000) Can somebody tell what is the problem

  • jQuery and AJAX?

    - by Moshe
    I'm making a simple form which has 5 input elements for parts of an address. I use jQuery to build and send an AJAX request to a PHP file on my server. For some reason my jQuery is not properly able to read the values from my input elements. What could be wrong? Here is my jQuery: $('#submitButton').click(function(){ $('#BBRequestBox').html('<img src="images/loading.gif" />'); alert('Info: ' + $('#name').val() + ' ' + $('#street').val() + ' ' + $('#city').val() + ' ' + $('#state').val() + ' ' + $('#zip').val() + ' '); $.ajax({ type: "POST", url: "./bbrequest.php", data: {name: $('#name').val(), street: $('#street').val(), city: $('#city').val(), state: $('#state').val(), zip: $('#zip').val() }, success: function(msg){ $('#BBRequestBox').html('<p>' + msg + '</p>'); }, error: function(XMLHttpRequest, textStatus, errorThrown){ $('#BBRequestBox').html('<p> There\'s been an error: ' + errorThrown + '</p>'); } }); return false; }); Here is my HTML: <form action="#"> <label>Name:</label><input type="text" id="name" class="textbox"/> <label>Street:</label><input type="text" id="street" class="textbox" /> <label>City:</label><input type="text" id="city"class="textbox" /> <label>State:</label><input type="text" id="state" class="textbox"/> <label>Zip:</label><input type="text" id="zip" class="textbox" /> <input type="submit" value="Send Me a Bitachon Builder!" id="submitButton" /> </form>

  • How do I create a new project in TFS from an existing project (breaking history)?

    - by Lindsay
    My team is taking over a project from a previous team. We use a different TFS server than the original team, and we are also not interested in keeping the history of the project because we are accepting the latest version of the code as the beginning of our history with the project. Branching is not an option since we want to start our history from the current version of the code. We just want a fresh project with the existing code. I have not been able to create the new project from the old code successfully. I keep getting an error: "Source control cannot add the solution: Solution would span multiple workspaces" My process for attempting the new project creation: Create a workspace for the previous team's version of the code. Get latest version of that code into local mapped workspace directory Open the solution. Unbind all projects and solution. Close solution. Create a workspace for the new version of the code on our TFS server. Copy the unbound code on my local box to the new local workspace mapped folder. Open the solution from the new directory. "Add to source control" from the new solution. Then I get the error. I have tried removing the TFS security files out of the code directories in the unbound version and tried changing source control instead of adding to source control (but it just binds back to the original instead of letting me bind to the new). Is there any other way to do this besides recreating the solution/projects and adding back all the files and references? It doesn't seem like it should be this difficult... Any advice much appreciated!
