• Using Variables for Class Names in Python?

  - by Sam McAfee

  I want to know how to use variables for objects and function names in Python. In PHP, you can do this: $className = "MyClass"; $newObject = new $className(); How do you do this sort of thing in Python? Or, am I totally not appreciating some fundamental difference with Python, and if so, what is it?

• Should I use an ArrayList or IList

  - by Farstucker

  Im using the .NET framework 1.1 and Im hoping someone could help me implement a dynamic array of objects? A watered-down example of the object I wish use is below. Class CarObj { public string CarName; public string CarYear; } Should I use an ArrayList or do you think it would be better to make a CarList class to implement an IList interface? Is there a performance benefit for one over another?

• Zend_Registry: real life examples

  - by takeshin

  Do you find Zend_Registry useful? For which tasks it should be used? For which not? Global state for variables is not a good practice. Main objects may have global state injected via $front->setParam('paramName', $object), so what's the purpose of Zend_Registry?.

• How to create dynamic number of output files with SSIS?

  - by JSacksteder

  I will be creating flatfiles and based on the data in the batch, it might be necessary to split the data into an undetermined number of files. I can make the connection string dynamic with an expression, but that is only evaluated when the package starts. I'd like to change that expression to include a '-a' or '-b' in the filename. Alternately, if I have to create new connection manager objects at run time on demand, how do I go about that?

• .NET object creation and generations

  - by nimoraca

  Is there a way to tell the .NET to allocate a new object in generation 2 heap. I have a problem where I need to allocate approximately 200 MB of objects, do something with them, and throw them away. What happens here is that all the data gets copied two times (from gen0 to gen1 and then from gen1 to gen2).

• Network Differences

  - by Chris

  I am busy working on a java app to run on blackberries but on some devices i am testing on, the code does not seem to be working and im having a hard time pinpointing where the problem lies. My question is: Could the problem with some phones working and not working have t odo with the type of network they are running on such GSM vs CDMA and would the code that stops working on some devices be in one of the following areas: 1) Listeners - such as MessageListener and Phone Listener 2) UI Objects - simple test labels and buttons 3) Connection to a web service using ksoap2

• STL map - insert or update

  I have a map of objects and I want to update the object mapped to a key, or create a new object and insert into the map. The update is done by a different function that takes a pointer to the object (void update(MyClass *obj)) What is the best way to "insert or update" an element in a map?

• What does the length attribute do when set on the @Column JPA annontation?

  - by James McMahon

  What exactly does setting the length on a column do in JPA? @Column(name = "middle_name", nullable = false, length = 32) public String getMiddleName() { return this.middleName; } I understand that you can use the annotations to generate the database schema based on the entity objects, but does length do any sort of check or truncation when persistence happens, or it solely used for schema creation? I also realize that JPA can sit on top of various implementations, the implementation I am concerned with in this case, is Hibernate.

• How do I declare a constructor for an 'object' class type in Scala? I.e., a one time operation for the singleton.

  - by Zack

  I know that objects are treated pretty much like singletons in scala. However, I have been unable to find an elegant way to specify default behavior on initial instantiation. I can accomplish this by just putting code into the body of the object declaration but this seems overly hacky. Using an apply doesn't really work because it can be called multiple times and doesn't really make sense for this use case. Any ideas on how to do this?

• Refactoring nested foreach statement

  - by dotnetdev

  Hi, I have a method with a nested foreach collection (iterate a set of objects and then look inside each object). I saw in a book a good pattern to make this much more elegant but cannot remember/find the code example. How else could I make this more tidy? The code is just a typical nested foreach statement so I have not provided a code sample. Thanks

• Unity 2.0 and policy injection in .config

  - by marcusoft.net

  I want to use unity (2.0) to resolve my dependencies in a way so that i can configure policy injection (policies, matching rules and call handlers) in the .config file. Or an other way to put it; i want my resolved objects to be "policy enabled", so that i can add and change to policies in config without have to recompile. Any ideas on how to do that?

• Is this the best approach using generics to check for nulls

  - by user294747

  public static T IsNull<T>(object value, T defaultValue) { turn ((Object.Equals(value,null)) | (Object.Equals(value,DBNull.Value)) ? defaultValue : (T)value); } public static T IsNull<T>(object value) where T :new() { T defaultvalue = new T(); return IsNull(value, defaultvalue); } Have tested, and can use against data objects, classes and variables. Just want to know if there is better way to go about this.

  When using Zend Studio to write views for a MVC framework, is there any way of having those variables autocomplete, perhaps using PHPdoc? For example, I set a variable in a view called $cart which is an instance of my ShoppingCart class. When I type "$cart-", I'd like the IDE to pop up with all of the objects properties.

• python: list manipulation

  - by Jason S

  I have a list L of objects (for what it's worth this is in scons). I would like to create two lists L1 and L2 where L1 is L with an item I1 appended, and L2 is L with an item I2 appended. I would use append but that modifies the original list. How can I do this in Python? (sorry for the beginner question, I don't use the language much, just for scons)

• Retrieving Data in A NSTableView

  - by Heisennberg

  I have a three column Table View populated by two NSMutableDictionaries which share the same keys (ie key | value1 | value2 ) with dict1(key,value1) and dict2(key,value2). I want to manually enter data in the third column and create the key/value objects in dict2. But when I do that, my code picks the wrong key :S Here's the code for the delegate : - (void)tableView:(NSTableView *)aTableView setObjectValue:(id)anObject forTableColumn:(NSTableColumn *)aTableColumn row:(NSInteger)rowIndex { if ([[aTableColumn identifier] isEqualToString:@"value2"]) { [dict2 setValue:anObject forKey:[[[aTableView tableColumnWithIdentifier:@"key"] dataCellForRow:rowIndex] stringValue ]]; } } Any idea ?

• How to span multile tables in Django

  The Django documentation gives en example like so: b = Blog.objects.get(id=1) b.entry_set.all() Which from what I understand results in 2 queries. What if I wanted to get the blog, the blog entries and all the comments associated with that entry in a number of queries that does not depend on the number of entries? Or do I have to drop down to SQL to do that?
