    - by Ben
    I am working on a Symfony project and I currently have this: <?php echo preg_replace('/\n/','<br />', $review->getComments()); ?> and would very much like to be able to make all getters add html line breaks so i don't have to pepper my code with preg_replace. the $object-getFieldname methods are work automatically so I am looking to extend this somewhere to globally add a new method.

  • C# Reflection - Casting private Object field

    - by alhazen
    I have the following classes: public class MyEventArgs : EventArgs { public object State; public MyEventArgs (object state) { this.State = state; } } public class MyClass { // ... public List<string> ErrorMessages { get { return errorMessages; } } } When I raise my event, I set 'State' of the MyEventArgs object to an object of type MyClass. I'm trying to retrieve ErrorMessages by reflection in my event handler: public static void OnEventEnded(object sender, EventArgs args) { Type type = args.GetType(); FieldInfo stateInfo = type.GetField("State"); PropertyInfo errorMessagesInfo = stateInfo.FieldType.GetProperty("ErrorMessages"); object errorMessages = errorMessagesInfo.GetValue(null, null); } But this returns errorMessagesInfo as null (even though stateInfo is not null). Is it possible to retrieve ErrorMessages ? Thank you

  • SQL Select - adding field to Select is changing the results

    - by nycdan
    I'm stumped by this SQL problem that I suspect will be easy pickings for someone out there. I have a table that contains rows representing several daily lists of ranked items. The relevent fields are as follows: ID, ListID, ItemID, ItemName, ItemRank, Date. I have a query that returns the items that were on a list yesterday but not today (Items Off List) as follows: Select ItemID, ListID, ItemName, convert(varchar(10),MAX(date),101) as date, COUNT(ItemName) as days_on_list From Table Group By ItemID, ListID, ItemName Having Max(date) = DATEADD("d",-1,convert(varchar(10),getdate(),101)) and ListID = 1 Order By ListID, ItemName, COUNT(ItemName) Basically I'm looking for records where the max date is yesterday. It works fine and shows the number of days each item was previously on the list (although not necessarily consecutively, but that's fine for now). The problem is when I try to add ranking to see what yesterday's rank was. I tried the following: Select ItemID, ListID, ItemName, ranking, convert(varchar(10),MAX(date),101) as date, COUNT(ItemName) as days_on_list From Table Group By ItemID, ListID, ItemName, ranking Having Max(date) = DATEADD("d",-1,convert(varchar(10),getdate(),101)) and ListID = 1 Order By ListID, ItemName, ranking, COUNT(ItemName) This returns a great deal more records than the previous query so something isn't right with it. I want the same number of records, but with the ranking included. I can get the rank by doing a self-join with a subquery and getting records where the ItemID occurs yesterday but not today - but then I don't know how to get the Count any more. Appreciation in advance for any help with this. ======== SOLVED ============== Select ItemID, ListID, ItemName, ranking, convert(varchar(10),MAX(date),101) as date, COUNT(ItemName) as days_on_list from Table T Where date = DATEADD("d",-1,convert(varchar(10),getdate(),101)) and ListID = 1 and T.ItemID Not In (select T.ItemID from Table T join Table T2 on T.ItemID = T2.ItemID and T.ListID = T2.ListID where T.date = DATEADD("d",-1,convert(varchar(10),getdate(),101)) and T2.date = convert (varchar(10),getdate(),101) and T.ListID = 1) Group by ItemID, ListID, ItemName, ranking Basically, what I did was create a subquery that finds all items that appear in both days, and finds items that appeared yesterday but are not in the set of items that appeared both days. Then I was able to do the aggregate function and grouping correctly. I would NOT be surprised if this is more convoluted than necessary but I understand it and can modify it as needed and performance doesn't seem to be an issue. Thanks everyone for the assist.

  • Where to Store ID Field In Silverlight

    - by Blake Blackwell
    I am trying to use the MVVM pattern, and I am wondering where I place an ID value. Do I create a TextBlock that has its visibility property set to collapsed? Or is there a better place to store this kind of data? Currently the command parameter is set to: CommandParameter="{Binding ElementName=Name,Path=Text}" But I'd rather it be something like: CommandParameter="{Binding ElementName=Id,Path=Text}" I'm totally up for suggestions on what the best way there is to do this, since I'm new to this pattern and presentation language. <ListBox x:Name="MyListBox" ItemsSource="{Binding MyData, Mode=TwoWay}" BorderThickness="0"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal"> <CheckBox x:Name="Visible" IsChecked="{Binding Visible, Mode=TwoWay}" Command="{Binding ElementName=MyListBox, Path=DataContext.MyCommand}" CommandParameter="{Binding ElementName=Name,Path=Text}" /> <TextBlock Text="{Binding Name}" /> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> EDIT: Option 1 <CheckBox x:Name="Visible" IsChecked="{Binding Visible, Mode=TwoWay}" Command="{Binding ElementName=MyListBox, Path=DataContext.MyCommand}" CommandParameter="{Binding Id}" /> This option gives me just the Id, which is useful in many situations. EDIT: Option 2 <CheckBox x:Name="Visible" IsChecked="{Binding Visible, Mode=TwoWay}" Command="{Binding ElementName=MyListBox, Path=DataContext.MyCommand}" CommandParameter="{Binding}" /> This option gives me the full model, which is even useful for my particular situation.

  • URL Encoding of Characters in a password field

    - by Alavoil
    I am trying to pass login credentials to a PHP script that I have in my iPhone app. When I pull a password with special characters the password is missing certain characters especially the percent sign. I am trying to encode the text but even before I send it, the percent sign is missing. //password_field is a UITextField holding the password: !@#$%^&*() NSString *tmpPass = [password_field.text stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; NSLog(p_field.text); NSLog(tmpPass); This is what appears in the console: !@#$^&*() [email protected]&*() Is there any reason why it would be dropping the percent sign?

This is the line: if ( value == '1' || value == '4' || value == '7' || value == '18') {

  • Puting contact number into field

    - by dfilkovi
    I have this code that has one button that let's me choose an entry from contacts, and passes that choesn contact to onActivityResult function. My question is how do I select data of that single contact when all that is passed is an Intent in data variable. That data variable, if converted to string shows something like "dat: content://contacts/people/4" so I see that selected contact is somehow passed, but what now? How to get that data? And also all I found by googling was examples with deprecated class People, so I don't know how too use new classes. Please help. Thank you. public class HelloAndroid extends Activity { private static final int CONTACT_ACTIVITY = 100; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); final Button contactButton = (Button) findViewById(R.id.pick_contact_button); contactButton.setOnClickListener(new OnClickListener() { public void onClick(View v) { Uri uri = Uri.parse("content://contacts/people"); Intent contacts_intent = new Intent(Intent.ACTION_PICK, uri); startActivityForResult(contacts_intent, CONTACT_ACTIVITY); } }); } public void onActivityResult(int requestCode, int resultCode, Intent data){ super.onActivityResult(requestCode, resultCode, data); switch(requestCode){ case(CONTACT_ACTIVITY): { if(resultCode == Activity.RESULT_OK) { alertText(data.toString()); } break; } } } }

  • MySQL 5.1 implicit cast from now() to a date field

    - by Savageman
    Hello, I have an issue with MySQL 5.1. A datetime data type isn't implicitly casted to match a date column. SELECT * FROM my_table WHERE my_date_field = NOW() This request doesn't return any rows using MySQL 5.1, but works well with version 5.0. If we use CURDATE() instead of NOW() it works both in MySQL 5.0 and MySQL 5.1. If the cast is explicit (CAST(NOW() AS DATE)), it also works both in MySQL 5.0 and MySQL 5.1. The problem only appears with implicit cast from datetime to date. Doesn't anyone already encountered this issue or has a clue about how to solve this problem? I know it's not the best to use NOW() instead of CURTIME(), but this isn't the question here. It is currently used in an application and the purpose is to avoid rewriting everything. Thanks!

  • Django: ordering by backward related field property

    - by Silver Light
    Hello! I have two models related one-to-many: a Post and a Comment: class Post(models.Model): title = models.CharField(max_length=200); content = models.TextField(); class Comment(models.Model): post = models.ForeignKey('Post'); body = models.TextField(); date_added = models.DateTimeField(); I want to get a list of posts, ordered by the date of the latest comment. If I would write a custom SQL query it would look like this: SELECT `posts`.`*`, MAX(`comments`.`date_added`) AS `date_of_lat_comment` FROM `posts`, `comments` WHERE `posts`.`id` = `comments`.`post_id` GROUP BY `posts`.`id` ORDER BY `date_of_lat_comment` DESC How can I do same thing using django ORM?

  • SQL command to get field of a maximum value, without making two select

    - by António Capelo
    I'm starting to learn SQL and I'm working on this exercise: I have a "books" table which holds the info on every book (including price and genre ID). I need to get the name of the genre which has the highest average price. I suppose that I first need to group the prices by genre and then retrieve the name of the highest.. I know that I can get the results GENRE VS COST with the following: select b.genre, round(avg(b.price),2) as cost from books b group by b.genre; My question is, to get the genre with the highest AVG price from that result, do I have to make: select aux.genre from ( select b.genre, round(avg(b.price),2) as cost from books b group by b.genre ) aux where aux.cost = (select max(aux.cost) from ( select b.genre, round(avg(b.price),2) as cost from books l group by b.genre ) aux); Is it bad practice or isn't there another way? I get the correct result but I'm not confortable with creating two times the same selection. I'm not using PL SQL so I can't use variables or anything like that.. Any help will be appreciated. Thanks in advance!
