We have a bunch of C/C++ modules and projects for QNX4, QNX6 and Linux. All of these are written in Eclipse/QNX Momentics and we use Project Sets (psf files) to combine different modules into projects as required. The projects are built using make. The psf files specify which modules are required for a certain project. I have looked at ...

Probabaly a newbie question here. Is there a way for the user to drag resize QTableWidget? My QTableWidget is nested inside a tab widget, therefore it is not a window by itself. I tried implementing a QSizeGrip, but when I drag resize the grip the entire window resizes and not just the table. ...
This is very odd. We have some managed C++ (an assembly) which uses a .NET COM interop dll generated by TlbImp to make calls into a COM object. When we register the COM DLL we specify that we want it to execute within a surrogate (the "DLLSurrogate" registry entry). Our COM DLL is 64-bit and is executing on a 64-bit platform. When we ...
Hi, I am building a graph class based on the following suggestion: http://stackoverflow.com/questions/671714/modifying-vertex-properties-in-a-boostgraph Unfortunately, I realized an unexpected behavior. When using my own vertex-properties (for simplicity please ignore the edge properties), the built-in properties seem not to be used. S...
Hi I have class A and classes B and C. class B runs one thread and class C runs n threads. class A should start the threads and than wait for a signal from the user (say Ctrl-c in Linux) - class A will stop all threads (of classes B and C), do some final work and the application will exit. The question is: how should class A sleep unti...

I have an object (Client * client) which starts multiple threads to handle various tasks (such as processing incoming data). The threads are started like this: // Start the thread that will process incoming messages and stuff them into the appropriate queues. mReceiveMessageThread = CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)receive...

The problem with lexical_cast is that it uses stringstream for conversion. If you are working in a multi-threaded environement any stream class from ...
Hello everyone, I am totally new to math/numerical analysis programming and I was looking all over the internet to find appropriate libraries. What I stumbled upon are CLAPACK, Boost::uBLAS, ATLAS. I need to solve SLEs (system of linear equations) so I guess BLAS itself would not be sufficient without some implementation of LAPACK. No...
