Python Newbie: Returning Multiple Int/String Results in Python

Hello, I have a function that has several outputs, all of which "native", i.e. integers and strings. For example, let's say I have a function that analyzes a string, and finds both the number of words and the average length of a word. In C/C++ I would use @ to pass 2 parameters to the function. In Python I'm not sure what's the right ...

How do you use GAC'd assemblies as references with csc.exe?

I'm compiling from csc.exe (well, CruiseControl is...), and I need to reference a DLL in the GAC. I do not have the correct version of this DLL as a simple file, but there is a correct version in the GAC. However, you can't reference assemblies in the GAC with csc -- you have to have the path to the actual file. I've found some refere...

How do you keep a persistent reference between two apps on the windows platform even if one crashes and re-opens?

What are some options for keeping a persistent reference to two applications even if one crashes so that when re-opening the first one, it can get a reference to the second one and call methods on it. The situation is as follows: App1 (a web browser plugin) instantiates App2 via a object reference in an HTML page and gets a reference ...

Reference to pointers and C++ polymorphism

Catching wrong array reference in C++

How do I catch wrong array reference in C++? Why doesn't the following code work: #include <exception> int * problemNum = new int; int (* p [100])() = {problem1, problem2, problem3}; ... try { cout << (*p[*problemNum-1])(); } catch (exception){ cout << "No such problem"; } My compiler...

speed of references in C++

Hi, I have been working on a project and trying to find the source of a large slowdown in execution time and have narrowed it down to a single method which I have managed to optimise out of the logic. The problem is that my solution involves using a reference which makes another section of the code run quite slowly... The question I'd li...

Getting a reference in .net code to an already running process

Is it possible in managed code to get a reference to an already running process (COM+ component) and call methods on it? Instead of instantiating a new object, is there a way to point to an already running instance of a COM object so that the .net code has a reference to the running process just as if it had instantiated it - to call me...

How can I elegantly create a hash from an array reference in Perl?

Hi, I am looking for a more elegant way to create a hash that contains the list I have read in from my configuration file.

SAS Pocket Reference

I'm looking for a SAS pocket reference that provides listings of SAS procedures/statements. I don't want detailed explanations of each procedure - just a list of the procedures and maybe a short description to jog one's memory. A sublist of the statements associated with each procedure would be helpful. Something along the lines of the O...

Managed CPP reference paths?

I'm trying to compile a managed cpp application from the command line. Suppose my cpp application references the .NET 2.5 framework's "System.dll". I can compile like this, without problems: cl /clr /FU"System.dll" main.cpp The application then works as expected. If, however, I try to reference the .NET 3.5 framework's "System.core...

I don't use SQL Server Cursors often but when I do, I always have to look up the syntax and options. So I wanted to ask, what is the best SQL Server Cursor reference on the web?.

Adding an ActiveX dll to a .Net project as reference works on one dev's machine, but not on another one?

Good afternoon, we're having a semi-weird problem here with a legacy activex dll that needs to be used in a .net project and strangely it works perfectly fine (adding it as a reference and all its functionality) on one developer's machine, but on no other ones, the build-server complains about a faulty reference etc etc. Whenever e.g. ...

I am trying to find a reference for the Video Components that come with flash. I have added them to a MovieClip and I want to control them, but I cannot find any documentation on these classes.

Problems building a VB.NET 2008 express project referencing a dll

I have written a program in VB.NET 2008 Express that references a .NET managed dll. I simply added a reference to the dll to the project.

When is it preferable to store data members as references instead of pointers?

Let's say I have an object Employee_Storage that contains a database connection data member. Should this data member be stored as a pointer or as a reference? If I store it as a reference, I don't have to do any NULL checking. (Just how important is NULL checking anyway?) If I store it as a pointer, it's easier to setup E...
