• Using CookieJar in Python to log in to a website from "Google App Engine". What's wrong here?

  - by brilliant

  Hello everybody, I've been trying to find a python code that would log in to my mail box on yahoo.com from "Google App Engine" . Here (click here to see that page) I was given this code: import urllib, urllib2, cookielib url = "https://login.yahoo.com/config/login?" form_data = {'login' : 'my-login-here', 'passwd' : 'my-password-here'} jar = cookielib.CookieJar() opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(jar)) form_data = urllib.urlencode(form_data) # data returned from this pages contains redirection resp = opener.open(url, form_data) # yahoo redirects to http://my.yahoo.com, so lets go there instead resp = opener.open('http://mail.yahoo.com') print resp.read() The author of this script looked into HTML script of yahoo log-in form and came up with this script. That log-in form contains two fields, one for users' Yahoo! ID and another one is for users' password. Here is how HTML code of that page for both of those fields looks like: User ID field: <input type="text" maxlength="96" class="yreg_ipt" size="17" value="" id="username" name="login"> Password field: <input type="password" maxlength="64" class="yreg_ipt" size="17" value="" id="passwd" name="passwd"> However, when I uploaded this code to Google App Engine I discovered that this log-in form keeps coming back to me, which, I assume, means that logging-in process didn't succeed. Why is it so?

• Function returning a class containing a function returning a class

  - by Scott

  I'm working on an object-oriented Excel add-in to retrieve information from our ERP system's database. Here is an example of a function call: itemDescription = Macola.Item("12345").Description Macola is an instance of a class which takes care of database access. Item() is a function of the Macola class which returns an instance of an ItemMaster class. Description() is a function of the ItemMaster class. This is all working correctly. Items can be be stored in more than one location, so my next step is to do this: quantityOnHand = Macola.Item("12345").Location("A1").QuantityOnHand Location() is a function of the ItemMaster class which returns an instance of the ItemLocation class (well, in theory anyway). QuantityOnHand() is a function of the ItemLocation class. But for some reason, the ItemLocation class is not even being intialized. Public Function Location(inventoryLocation As String) As ItemLocation Set Location = New ItemLocation Location.Item = item_no Location.Code = inventoryLocation End Function In the above sample, the variable item_no is a member variable of the ItemMaster class. Oddly enough, I can successfully instantiate the ItemLocation class outside of the ItemMaster class in a non-class module. Dim test As New ItemLocation test.Item = "12345" test.Code = "A1" quantityOnHand = test.QuantityOnHand Is there some way to make this work the way I want? I'm trying to keep the API as simple as possible. So that it only takes one line of code to retrieve a value.

• Default entries on a first time creation for a serialized class

  - by MGSoto

  I have a class I am using for serializing various configuration options for an application I am working on. I'm adding a new property to the class that is a List, and I'd like it to fill this list if it does not exist already in a XML file. My first thought was to check if the list contained zero items, however this is not acceptable because there are times I want to have zero items in the list. In essence I want a file that has been serialized with an older version of the same class to be "upgraded" and have defaults automatically inserted for new properties. How can I do this? For a more visual example of what I'm trying to do, see below: When I deserialize an XML file that contains: <Item1>wtfe</Item1> <Item2>wtfe</Item2> and after I've added a list property it will serialze as: <Item1>wtfe</Item1> <Item2>wtfe</Item2> <Item3/> I want it to serialize as: <Item1>wtfe</Item1> <Item2>wtfe</Item2> <Item3> <DefaultSubItem/ Field="wtfe"> <DefaultSubItem/ Field="wtfe"> </Item3> But allow me to change it to: <Item1>wtfe</Item1> <Item2>wtfe</Item2> <Item3></Item3>

• Ant path/pathelement not expanding properties correctly

  - by Jonas Byström

  My property gwt.sdk expands just fine everywhere else, but not inside a path/pathelement: <target name="setup.gwtenv"> <property environment="env"/> <condition property="gwt.sdk" value="${env.GWT_SDK}"> <isset property="env.GWT_SDK" /> </condition> <property name="gwt.sdk" value="/usr/local/gwt" /> <!-- Default value. --> </target> <path id="project.class.path"> <pathelement location="${gwt.sdk}/gwt-user.jar"/> </path> <target name="libs" depends="setup.gwtenv" description="Copy libs to WEB-INF/lib"> </target> <target name="javac" depends="libs" description="Compile java source"> <javac srcdir="src" includes="**" encoding="utf-8" destdir="war/WEB-INF/classes" source="1.5" target="1.5" nowarn="true" debug="true" debuglevel="lines,vars,source"> <classpath refid="project.class.path"/> </javac> </target> For instance, placing an echo of ${gwt.sdk} just above works, but not inside "project.class.path". Is it a bug, or do I have to do something that I'm not? Edit: I tried moving the property out from target setup.gwtenv into "global space", that helped circumvent the problem.

• Black Corners On Grouped UITableViewCells Only After Navigation Pops

  - by coneybeare

  I am not graphics expert but I somehow managed to make some good looking custom grouped UITableViewCells by setting the background view to a backgroundView with some CG code. In all SDK's up to 3.1.3 (maybe 3.2... I haven't tested on the iPad) this was working great, but I think a more recent SDK has introduced a change in the way graphics are cached offscreen. Upon first render, everything is great: The drawing is fine and the corners are transparent. If I push a couple of view controllers on the navigation stack and come back, there are now black corners that appear in the views: BEFORE && AFTER I have tons of code, most of which is written up here. I have tried tweaking to the best of my ability, looking at the docs for applicable changes, but after at least 8 hours in I still cannot find what might cause this. I have tried setting every view I can think of to be backgroundColor=clearColor and opaque=NO What else am I missing? Any debugging tips? UPDATE: I have some debug code in viewDidAppear that prints the backgroundColor and class description of all the subviews. - (void)debugView:(UIView *)view { DebugLog(@"%@ - %@", view.backgroundColor, [[view class] description]); for (UIView* child in view.subviews) { [self debugView:child]; } } - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; [DownloadController.networkQueue setSuspended:NO]; for (TTTableViewCell *cell in [self.tableView visibleCells]) { [cell debugView:cell]; } } With this code, I inspect the backgroundColor settings of the cell views on first load, when it is fine, and then again after coming back. There are some differences, but all the colors are still set to be clear. This leads me to believe the issue is underneath the UITableViewCell. UPDATE 2: I have created a simple sample application to highlight the problem here

• JavaScript change to DropDownList.SelectedIndex not submitted

  - by Bellfalasch

  Hi So, I have a form to submit fighters. You write his/her name, country, and then the team they fight for + the team's country. When you start typing the name I have constructed my own Ajax AutoCompleter. It will find existing fighters that might match. When you click on one of the suggestions it will populate up to four fields depending on existing data in the database. If you're lucky the fighter already exists with information on country, team, and the team's country. The problems starts when submitting. The JavaScript follows and just get's the id of the country to select (also the value of the select-option), and the select-element itself. function dropdownSelect(value, element) { var dropdown = document.getElementById(element); for (var i = 0; i < dropdown.options.length; i++) { if (dropdown.options[i].value == value) { dropdown.options[i].selected = true; return true; } } } When submitting the ASP.NET-code halt's and says that my country-field is null. So my JavaScript-change of selected field couldn't be read by ASP.NET. Is this a limitation of how ASP.NET works? Or a limitation of my skills? ;P

• Ideas for storing e-mail messages in a Delphi client server application

  - by user193655

  There are many suggestions here and there for storing e-mail messages. Somehow what I am doing is writing an Outlook addin to send emails from inbox/sent folders directly to my application. So only what is really interesting is saved. And I decide where to save it. Imagine this case: I recieve an email from a customer. It's up to me to decide whether I should save it on the customer or on the order 24 that that customer did. So this is why I am doing the add in, and not some automatic storing of emails = noise after some time. This said, how to store the emails? For the emails that I recieve or send through Outlook the idea could be save the whole file in a blob field (so the eml file), may be I can save also other info (like the subject) in another text field. But the problem comes when I write an email from my application. In this case I am not generating an eml file, I send through MAPI data to Outlook to compose an email that I will send with Outlook (so in this case I cannot save the eml), or I directly send it with Indy. Also in this case I don't have the eml file... One idea could be that the all the emails that I auto compose have a special flag that the Add in recognises and therefore when I send the mail it is stored back to the DB. So in this case I can save the eml also of the mails I sent from my application. May you comment?

• How to map a 0..1 to 1 relationship in Entity Framework 3

  - by sako73

  I have two tables, Users, and Address. A the user table has a field that maps to the primary key of the address table. This field can be null. In plain english, Address exist independent of other objects. A user may be associated with one address. In the database, I have this set up as a foreign key relationship. I am attempting to map this relationship in the Entity Framework. I am getting errors on the following code: <Association Name="fk_UserAddress"> <End Role="User" Type="GenesisEntityModel.Store.User" Multiplicity="1"/> <End Role="Address" Type="GenesisEntityModel.Store.Address" Multiplicity="0..1" /> <ReferentialConstraint> <Principal Role="Address"> <PropertyRef Name="addressId"/> </Principal> <Dependent Role="User"> <PropertyRef Name="addressId"/> </Dependent> </ReferentialConstraint> </Association> It is giving a "The Lower Bound of the multiplicity must be 0" error. I would appreciate it if anyone could explain the error, and the best way to solve it. Thanks for any help.

• javascript check function for a html form

  - by Reteras Remus

  I'm having a problem with a HTML form (name, e-mail, subject, message), I can't validate the form if it was completed correct or not. I want to call a javascript function when the form is submitted and alert if a field wasn't completed correct. My problem is with the submit button, because my boss said that I must use he's own php function to insert a submit button. The php function looke like: function normal_button($text, $width, $param = '', $class = 'button-blue') { $content = '<div class="'.$class.'" style="width:'.$width.'px;" '.$param.'>'.$text.'</div>'; return $content; } and how I call the function: echo normal_button('Send it', '100', 'onclick="document.getElementById(\'emailForm\').submit();" '); I tried to call the js function declaring the onSubmit="return checkForm(this)" in the <form action='email.php' method='post'> HTML form, but I can't "catch" the submit. Also I tried to catch it with jquery, $(document).ready(function() { $('.normal_button').click(function() { }); ); but I can't return false if a field wasn't completed correct. I must use he's PHP function to insert the submit button, but how can I "catch" the fields, how can I validate them? Any suggestions? Thank you !

• Is going for a BCS the right move for me?

  - by Michel Carroll

  I'm at a fork in the road. I need somebody to give me some advice from their personal journey in IT. At the moment, I have a college diploma (2 years) in Computer Programmer, and about 2 years of professional experience in the field of software. I'm currently freelancing my programming skills to the public, and am enjoying a nice income, and the rewards of flexibly working on a variety of projects with different cool people. I'm young (21 years old), passionate about software, technology, the internet, and also business. I know if I ever want to dwell deeper into the software industry, I might have a hard time doing so without a Bachelors in Computer Science. On one side, I think I'm better off getting my BCS while I'm still young and malleable. Also, the thought of learning even more stuff in my field is really exciting to me. On the flip side, it means another 3-4 years of studying, and jeopardizing my chances of going on vacation and accumulating wealth for a long time. Considering that I'm already pretty successful with my college diploma, do you think it's a good idea for me to go get my BCS? Will it open up many more doors in the future?

• Passing a WHERE clause for a Linq-to-Sql query as a parameter

  - by Mantorok

  Hi all This is probably pushing the boundaries of Linq-to-Sql a bit but given how versatile it has been so far I thought I'd ask. I have 3 queries that are selecting identical information and only differ in the where clause, now I know I can pass a delegate in but this only allows me to filter the results already returned, but I want to build up the query via parameter to ensure efficiency. Here is the query: from row in DataContext.PublishedEvents join link in DataContext.PublishedEvent_EventDateTimes on row.guid equals link.container join time in DataContext.EventDateTimes on link.item equals time.guid where row.ApprovalStatus == "Approved" && row.EventType == "Event" && time.StartDate <= DateTime.Now.Date.AddDays(1) && (!time.EndDate.HasValue || time.EndDate.Value >= DateTime.Now.Date.AddDays(1)) orderby time.StartDate select new EventDetails { Title = row.EventName, Description = TrimDescription(row.Description) }; The code I want to apply via a parameter would be: time.StartDate <= DateTime.Now.Date.AddDays(1) && (!time.EndDate.HasValue || time.EndDate.Value >= DateTime.Now.Date.AddDays(1)) Is this possible? I don't think it is but thought I'd check out first. Thanks

• Concept: Is mongo right for applying schemas?

  - by Jan

  I am currently in charge of checking wether it is valuable for one of our upcoming products to be developed on mongo. Without going too much into detail, I'll try to explain, what the app does. The app simply has "entities". These entities are technical stuff, like cell phones, TVs, Laptops, tablet pcs, and so forth. Of course, a cell phone has other attributes than a Tablet PCs and a Laptop has even other attributes, like RAM, CPU, display size and so on. Now I want to have something that we wanna call a scheme: We define that we need to have saved the display size, amount of ram size of flash devices, processor type, processor speed and so on for tablet pcs. For cell phone we might save display size, GSM, Edge, 3g, 4g, processor, ram, touch screen technology, bla bla bla. I think you got it :) What I want to realize is, that each "category" has a schema and when one of the system's users enters a new product (let's say the new iphone 4), the app constructs the form to be filled out with the appropriate attributes. So far it sounds nice and should not be a problem with mongo. But now the tough for which I could not find a clean solution.... An attribute modeled in mongo looks like: { _id: 1234456, name: "Attribute name", type: 0, "description" } But what to do, if i need this attribute in several languages, like: { en: {name: "Attribute name", type: 0, "description"}, de: {name: "Name des Attributs, type: 0, "Beschreibung"} } I also need to ensure that the german attribute gets updated as soon as the english gets updated, for instance when type changes from 0 to 1. Any ideas on that?

• addEventListener pass caller as argument

  Hi, I have the following code. And my problem is that when clicking, the event is firing but the argument passed is not the correct one. It is passing the last dynamically created row i.e. dataStructure.length value. Anyone knows a solution how to get around this? var table = document.getElementById('output'); for(i =0; i<dataStructure.length; i++){ var row = document.createElement('tr'); row.setAttribute('id', i); var url = dataStructure[i].url; if(document.addEventListener) row.addEventListener('click', function(){handleRowClick(i);}, false); var obj = dataStructure[i]; var cellCount = 0; for(field in obj){ var cell = document.createElement('td'); cell.setAttribute('id', cellCount++); //cell.addEventListener('click', function(){window.open(dataStructureObj.links[i].url);}, false); cell.innerHTML = obj[field]; row.appendChild(cell); } cellCount = 0; table.appendChild(row); } } function handleRowClick(rowClicked){ var rowHTML = rowClicked.innerHTML; var cells = rowHTML.getElementsByTagName('td'); for(cell in cells) { alert(cell.value); } window.open(cells[1].innerHTML); }

• Compound Primary Key in Hibernate using Annotations

  - by Rich

  Hi, I have a table which uses two columns to represent its primary key, a transaction id and then the sequence number. I tried what was recommended http://docs.jboss.org/hibernate/stable/annotations/reference/en/html_single/#entity-mapping in section 2.2.3.2.2, but when I used the Hibernate session to commit this Entity object, it leaves out the TXN_ID field in the insert statement and only includes the BA_SEQ field! What's going wrong? Here's the related code excerpt: @Id @Column(name="TXN_ID") private long txn_id; public long getTxnId(){return txn_id;} public void setTxnId(long t){this.txn_id=t;} @Id @Column(name="BA_SEQ") private int seq; public int getSeq(){return seq;} public void setSeq(int s){this.seq=s;} And here are some log statements to show what exactly happens to fail: In createKeepTxnId of DAO base class: about to commit Transaction :: txn_id->90625 seq->0 ...<Snip>... Hibernate: insert into TBL (BA_ACCT_TXN_ID, BA_AUTH_SRVC_TXN_ID, BILL_SRVC_ID, BA_BILL_SRVC_TXN_ID, BA_CAUSE_TXN_ID, BA_CHANNEL, CUSTOMER_ID, BA_MERCHANT_FREETEXT, MERCHANT_ID, MERCHANT_PARENT_ID, MERCHANT_ROOT_ID, BA_MERCHANT_TXN_ID, BA_PRICE, BA_PRICE_CRNCY, BA_PROP_REQS, BA_PROP_VALS, BA_REFERENCE, RESERVED_1, RESERVED_2, RESERVED_3, SRVC_PROD_ID, BA_STATUS, BA_TAX_NAME, BA_TAX_RATE, BA_TIMESTAMP, BA_SEQ) values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?) [WARN] util.JDBCExceptionReporter SQL Error: 1400, SQLState: 23000 [ERROR] util.JDBCExceptionReporter ORA-01400: cannot insert NULL into ("SCHEMA"."TBL"."TXN_ID") The important thing to note is I print out the entity object which has a txn_id set, and then the following insert into statement does not include TXN_ID in the listing and thus the NOT NULL table constraint rejects the query.

• NHibernate many-to-many relationship does not update join-table

  - by Davide Vosti

  I'm having trouble saving a many-to-many relationship with nhibernate. I searched and looked at almost every same question in SO and google but nothing works. The single classes are update correctly but nothing is inserted in the join-table. I have 2 classes: Event and Category. The mapping is this: Event: <bag name="Categories" access="field.camelcase-underscore" table="EventCategories" inverse="true" cascade="all-delete-orphan" lazy="true"> <key column="Event"/> <many-to-many class="Category" column="Category"/> </bag> Category: <bag name="Events" table="EventCategories" access="field.camelcase-underscore" cascade="all-delete-orphan" lazy="true" > <key column="Category"/> <many-to-many class="Event" column="Event"/> </bag> I tried to swap every parameter in both mappings but nothing works... Do you know what I'm doing wrong or have a right mapping for this case? Thank you very much!

Each owner has his item and when someone buy his item, owner gets an confirmation email, but when in cart is few same owner items, he gets several same email letters, so I need to remove dublicated array entries. I have tried to use DISTINCT and array_uniques functions but no luck. Any advices? I have an array and function to send mail.. function email($mail_array) { foreach(array_unique($mail_array) as $field => $value) { $result = mysql_query("select email from users where $field='$value'"); $row = mysql_fetch_array($result); $maail = mysql_real_escape_string($row['email']); $email_to = "".$maail.""; // rest of mail formatting code // create email headers $headers = 'From: '.$email_from."\r\n" . 'Reply-To: '.$email_from."\r\n" . 'X-Mailer: PHP/' . phpversion(); @mail($email_to, $email_subject, $email_message, $headers); } for ($i = 0; $i < $max; $i++) { $pid = $_SESSION['cart'][$i]['productid']; $owner = get_owner($pid); $mail_array = array( 'name' => $owner ); email($mail_array) //call function to send mail }

• Incorrect component when querying immediately after insert using NHibernate

  - by Am

  I have the following mapping for my table in MySql: <class name="Tag, namespace" table="tags" > <id name="id" type="Int32" unsaved-value="0"> <generator class="native"></generator> </id> <property name="name" type="String" not-null="true"></property> <component name="record_dates" class="DateMetaData, namespace" > <property name="created_at" type="DateTime" not-null="true"></property> <property name="updated_at" type="DateTime" not-null="true"></property> </component> </class> As you see the record_dates property is defined as a component field of type DateMetaDate. Both created_at and updated_at fields in 'tags' table are updated via triggers. Thus I can insert a new record like such: var newTag = new Tag() { name = "some string here" } Int32 id = (Int32)Session.Save(tag); Session.Flush(); ITag t = Session.Get<Tag>(id); ViewData["xxx"] = t.name; // -----> not null ViewData["xxx"] = t.record_dates.created_at; // -----> is null However when querying the same record back immediately after it was inserted the record_dates field ends up null even though in the table those fields have got values. Can any one please point out why the Session.Get ignores getting everything back from the table? is it because it caches the newly created record for which the records_dates is null? If so how can it be told to ignore the cached version?
