I want to intercept messages that are being sent to a window in a different process. What is the best way to do this? I can't see the messages when I use the WH_GETMESSAGE hook, and I'm not sure if I can subclass across processes? Any help would be much appreciated. ...

GetShortPathName() is not working as I expect on XP SP3 http://msdn.microsoft.com/en-us/library/aa364989(VS.85).aspx Is returning the input string for paths like: C:\Test\LongFolderNameToTestWith\BinarySearch.ini exactly as sent? Yet: C:\Documents and Settings\LocalService\NTUSER.DAT Does make short names for the path, so I kn...
I've written a few functions with a prototype like this: template <typename input_iterator> int parse_integer(input_iterator &begin, input_iterator end); The idea is that the caller would provide a range of characters, and the function would interpret the characters as an integer value and return it, leaving begin at one past the last...
Hi all, I'm trying to learn how to use managed/unmanaged code interop, but I've hit a wall that 4 hours of googling wasn't able to get over. I put together 2 projects in visual studio, one creating a win32 exe, and one creating a windows forms .NET application. After a bunch of mucking around I got the C# code to call into the c++...
One of the cool new features of the upcoming C++ standard, C++0x, are "rvalue references." An rvalue reference is similar to an lvalue (normal) reference, except that it can be bound to a temporary value (normally, a temporary can only be bound to a const reference): void FunctionWithLValueRef(int& a) {...} void FunctionWithRValueRef(in...
I need to use FormatMessage() for a project, but I don't like its scary interface. Does anyone know of a facade that tidies it up while still allowing for the replacement parameters? I just read the second part of the FastFormat introduction, and am considering writing an extension for FormatMessage() (or asking the FastFormat project t...
I have a simple (and also trivial) banking application that I wrote in C++. I'm on ubuntu so I'm using GNOME (GTK+). I was wondering if I could write all my GUI in C/GTK+ and then somehow link it to my C++ code. Is this even possible? Note: I don't want to use Qt or GTKmm, so please don't offer those as answers. ...
Hi all, I'm looking for a good book on the basics of C++. I'm relatively new to writing compiled code, and the last time I've actually coded ANYTHING was 2 years ago...basic PHP stuff. Online resources are GREAT and I would prefer something that is legally available for free. Any ideas? -FO ...
I have a couple of native applications written in C++ and C#. These are legacy applications that require data sharing between them. Currently, data sharing is through import/export of text file in some proprietary format. We are currently looking at integrating these two applications using eclipse. My questions are: How can we integrat...
The code below will print me the highest frequency it can find in my hash table (of which is a bunch of linked lists) 10 times. I need my code to print the top 10 frequencies in my hash table. I do not know how to do this (code examples would be great, plain english logic/pseudocode is just as great). I create a temporary hashing list ...
I was wondering, how is equality (==) established for STL iterators? Is it a simple pointer comparison (and thus based on addresses) or something more fancy? If I have two iterators from two different list objects and I compare them, will the result always be false? What about if I compare a valid value with one that's out of range? I...
Consider the following piece of code :- class A {}; class B : private A {}; B* bPtr1 = new B; // A* aPtr1 = bPtr1; // error // A* aPtr2 = static_cast<A*>(bPtr1); // error A* aPtr3 = (A*)bPtr1; B* bPtr2 = (B*)aPtr3; The C-style cast discards the private inheritance while both the implicit and static_cast fail (also dynamic_cast). Why...

hi all, i'd like to write a wrapper for a C++ framework. this framework is kinda buggy and not really nice and in C++. so i'd like to be able to call their methods from outside (via good old C file) of their framework by using just one shared lib. this sounds like the need for a wrapper that encapsulates the wanted framework methods fo...
I'm designing a networking framework which uses WSAEventSelect for asynchronous operations. I spawn one thread for every 64th socket due to the max 64 events per thread limitation, and everything works as expected except for one thing: Threads keep getting spawned uncontrollably by Winsock during connect and disconnect, threads that won...
I am going to be running an app(s) that require about 200MB of market data each time it runs. This is trivial amount of data to store in memory these days, so for speed thats what i want to do. Over the course of a days session I will probably run, re-run, re-write and re-run etc etc one or more applications over and over. SO, the ques...
I know this might be a long shot, but here it goes. I have several active projects and each has sub project library which gets compiled when the main project compiles. These libraries are dynamic ones, but recently there was an issue that might arise a need for those libraries (most of them are shared between projects) to be static inste...
I need a function that returns the ASCII value of a character, including spaces, tabs, newlines, etc... On a similar note, what is the function that converts between hexadecimal, decimal, and binary numbers? ...
I'm working with some Objective-C++ code (.mm files), and I'm curious if it's possible to get emacs to use proper syntax highlighting for both the Objective-C parts and the C++ parts. objc-mode and c++-mode are both major modes (built on top of cc-mode), so they can't be used at the same time. Are there any minor modes or elisp hacks a...
