• How can I use the compile time constant __LINE__ in a string?

  - by John

  I can use __LINE__ as a method parameter just fine, but I would like an easy way to use it in a function that uses strings. For instance say I have this: 11 string myTest() 12 { 13 if(!testCondition) 14 return logError("testcondition failed"); 15 } And I want the result of the function to be: "myTest line 14: testcondition failed" How can I write logError? Does it have to be some monstrosity of a macro?

• WPF: How to create a new class of user control in runtime?

  - by Entrase

  Hello! I need to define a user control in runtime and then instantiate it wherever I want. So it should not be just a "new UserControl()" (that will be an instance of a UserControl class) but the one I can use as a template. Should I use reflection to generate new type or is there a better way? Thanks!

• Are there any tools to speed up Cocoa development?

  - by user262325

  I noticed that there is much repeated work to do when creating Cocoa source code. For example, if I set an instance for an object: NSMutableArray *infoArray; I need add code: @property (retain,nonatomic) NSMutableArray *infoArray; @synthesize infoArray; in - (void)dealloc { I also need add: [infoArray release]; Is there any tool that can automate this, perhaps by automatically paste or copy the source code and add the repeated code at right place?

• When does the difference between a string and a number matter in Perl 5?

  - by Chas. Owens

  If a string in Perl 5 passes looks_like_number, it might as well be a number. For instance, my $s = "10" + 5; results in $s being assigned 15. Are there any cases where a string does not behave like it's numeric equivalent would have?

• How to approach huge code base of undocumented code?

  - by nimo9367

  I have recently been assigned a project to further develop an existing code base. The code doesn't contain any tests and not even one single line of comments. The whole "thing" is written in a really obfuscating manner so it takes a lot of time to figure out what happens. How do you usually approach this kind of problem? Tips and trix on how to handle this situation?

• Can Python's set absence of ordering be considered random order?

  - by Chuim

  Hello people. I'd like to know if the absence of element ordering of the Python's built-in set structure is "random enough". For instance, taking the iterator of a set, can it be considered a shuffled view of its elements? (If it matters, I'm running Python 2.6.5 on a Windows host.)

  - by MarcoB

• mod_rewrite with anchor link

  - by Graham

  Hi, thanks for looking. I know you can't redirect anchor URLs to another page, but is it possible to redirect a URL to only a single anchor? So http://www.example.com/video/{title} always gets sent to http://www.example.com/video.php?title={title}#player The only thing that changes is the title, anchor is always the same... I need to redirect to a certain slide on a coda slider

• Is it possible to write a database view that encompasses one-to-many relationships?

  - by Brandon Linton

  So I'm not necessarily saying this is even a good idea if it were possible, since the schema of the view would be extremely volatile, but is there any way to represent a has-many relationship in a single view? For example, let's say I have a customer that can have any number of addresses in the database. Is there any way to list out each column of each address with perhaps a number as a part of the alias (e.g., columns like Customer Id, Name, Address_Street_1, Address_Street_2, etc)? Thanks!

• What happens when I instantiate class in Python?

  - by Konstantin

  Could you clarify some ideas behind Python classes and class instances? Consider this: class A(): name = 'A' a = A() a.name = 'B' # point 1 (instance of class A is used here) print a.name print A.name prints: B A if instead in point 1 I use class name, output is different: A.name = 'B' # point 1 (updated, class A itself is used here) prints: B B Even if classes in Python were some kind of prototype for class instances, I'd expect already created instances to remain intact, i.e. output like this: A B Can you explain what is actually going on?

• How to declare ASP classic constants to a data type?

  - by Guy

  In asp classic and vbscript, you can declare a Const with a hexidecial value, and a date type value: Const C_LIGHTCYAN = &hCCFFEE Const C_STARTDATE = #1 JAN 2000# But how can I declare currency, single or doubles data types? Const C_LONG = 1024 '# I want this to be a LONG, not an INT! I'm sure I've seen something like Const C_LNG = L12345 or some other prefix/suffix combination for longs or doubles but can't find the source now

• deep or shallow copying?

  - by Dervin Thunk

  Dear all. I was wondering if there are examples of situations where you would purposefully pass an argument by value (deep copy) in C. For instance, passing a char to a function is usually cheaper in space than passing a char* (if there's no need to share the value), since char is 1 byte and pointers are, well, whatever they are in the architecture (4 in my 32 bit machine). ?(When) do you want to pass (big) deep copies to functions? if so, why?
