• Sample code for POST + cookie?

  - by OverTheRainbow

  Hello, I've been googling for some VB.Net code to authenticate to a web server with the POST method, receive a session ID in a cookie, and then send this cookie along with all GET queries... but all I found is half-working code or C# code, ie. difficult to use for a VB.Net newbie. Would someone have some code handy or some pointer that I could use to get started? Thank you.

• prolog. recursive function returning multiple values.

  - by obtur

  I am new in Prolog. I need to declare a function which looks at a list like [[1, 0, 0], [1, 0, 0], [1, 0, 0]] and if the value is 0 returns its address(by considering it as a double array). I wrote a function basicly in the format: function(..., X) :- function(called by other values). How can I write a function, that returns a value when each times it called(recursively). May I get them (in above question) as alternative X's???

• Debug.Assert Appears in Release Mode

  - by Ngu Soon Hui

  We all know that Debug.Assert will not be compiled into the dlls when compiled in release mode. But for some reason Debug.Assert did appear in the release version of a component I wrote. I suspect that I might have mess up my csproject setting. Any idea why Debug.Assert appears in release mode? P/S: I have double checked to make sure that I was really compiling in release mode before asking this question.

  I'm trying to write a regular expression that finds C#-style unescaped strings, such as string x = @"hello world"; The problem I'm having is how to write a rule that handles double quotes within the string correctly, like in this example string x = @"before quote ""junk"" after quote"; This should be an easy one, right?

• Custom Floating Point Representation

  - by Abion47

  I'm trying to write a parser that will read a particular file type, and I need to map the different data types to C# equivalents. Most of them aren't that difficult, but I'm having trouble wrapping my head around what "int16 with a bias of 14" means. I've deduced that it's some kind of floating point type, so my best bet would be to write a converter that would map it to a float, double, or decimal type. I'm not sure where to take it from here, though.

• merging indexed array in Python

  - by leon

  Suppose that I have two numpy arrays of the form x = [[1,2] [2,4] [3,6] [4,NaN] [5,10]] y = [[0,-5] [1,0] [2,5] [5,20] [6,25]] is there an efficient way to merge them such that I have xmy = [[0, NaN, -5 ] [1, 2, 0 ] [2, 4, 5 ] [3, 6, NaN] [4, NaN, NaN] [5, 10, 20 ] [6, NaN, 25 ] I can implement a simple function using search to find the index but this is not elegant and potentially inefficient for a lot of arrays and large dimensions. Any pointer is appreciated.

• C++ Pass a hidden arg to a class constructor?

  - by JP

  I would like to define a class that accept the pointer to it's parent class as an Argument, but would it be possible to somehow pass it without needing to pass it directly such as: class Child { public: Child(Parent* hiddenArg); }; class Parent { public: Child myChild; }; I know this is weird, but I am making my own Signal/Slot implementation and Child would be a signal defined, but I would like to get the parent so I can use it's Event Dispatcher...

• WinCheat / WinSpy-like tool for C++ Builder exes

  - by mawg

  I just came back to C++ Builder after 5 or more years away. I seem to remember a nice tool where I could drag its pointer over the GUI of my running application and get lots of info about what was pointed at - handle, size, text, parent, children, etc IIRC, if the exe include debug info I could also get the actual variable name as used in the source. Does anyone know what program I am talking about? Thanks
