In a C++ project (i.e. no .NET) on Windows Mobile, I am looking for a way to easily communicate between two independently running applications. Application A would run a service, whereas application B would provide the user some functionality - for which B has to call some of A's functions. I would rather not go through implementing anyt...
Is it possible to create Eclipse plugins that auto-discover eachother? I am developing a set of plugins that need to operate in two primary situations: individually in concert with each other. When run individually, the plugins should "just work" but when in concert, they will be sharing some of the same model content, and one of th...
In a C program (p1), how to launch a dynamically constructed command (and its arguments) that reads its standard input from p1's standard output? Note that: A method other than this stdout --> stdin piping is also OK provided it is PORTABLE across Windows and Linux. I cannot use C++, Java, Perl, Ruby, Python, etc here. Also, will t...

I have a project that I thought was going to be relatively easy, but is turning out to be more of a pain that I had hoped. First, most of the code I'm interacting with is legacy code that I don't have control over, so I can't do big paradigm changes. Here's a simplified explanation of what I need to do: Say I have a large number of si...
I'm developing a set of applications that work together to create a system for processing metering data. There's several reasons I want to have them loosely coupled and the system should be extensible by third parties, so the apps will be tied together via messaging.

I already have the serialization procedure worked out, and I understand that the pipes are sending binary streams. How should I go about sending my serialized data? I'm...
Is there a way for a Windows application to access another applications data, more specifically a text input field in GUI, and grab the text there for processing in our own application? If it is possible, is there a way to "shield" your application to prevent it? EDIT: The three first answers seem to be about getting the another applic...
