How to make Stack.Pop threadsafe
I am using the BlockingQueue code posted in this question, but realized I needed to use a Stack instead of a Queue given how my program runs. I converted it to use a Stack and renamed the class as needed. For performance I removed locking in Push, since my producer code is single threaded. My problem is how can thread working on the (...

Pitfalls when converting C++/CLI to C++
I have a library written in C++/CLI and I want to open it up. I want it to be as cross-platform as possible and be able to write bindings to it for other languages to use (Java, Python, etc, etc). To do this, the library needs to be in plain C++ for maximum flexibility. I figure that the logical structures are already there, I just need ...
Unreachable breakpoint at execut(able/ing) code
I've got two DLLs, one in written in native C++ and the other in C++/CLI. The former is injected into a process, and at a later point in time, loads the latter. While debugging, I noticed that the native DLL's breakpoints were functioning correctly while the other's weren't, even though its code was being executed. The breakpoints show...
Long/compound namespaces when using C++/CLI
I'm working on a project where a mixture of C# (95%) and C++/CLI (5%) are used. The namespace naming convention I'm aiming for is the good old Company.Technology.Etc..

Destructors not called when native (C++) exception propagates to CLR component
We have a large body of native C++ code, compliled into DLLs. Then we have a couple of dlls containing C++/CLI proxy code to wrap the C++ interfaces. On top of that we have C# code calling into the C++/CLI wrappers. Standard stuff, so far. But we have a lot of cases where native C++ exceptions are allowed to propagate to the .Net wor...

How can I (reasonably) precisely perform an action every N milliseconds?
I have a machine which uses an NTP client to sync up to internet time so it's system clock should be fairly accurate. I've got an application which I'm developing which logs data in real time, processes it and then passes it on. What I'd like to do now is output that data every N milliseconds aligned with the system clock. So for exampl...
Very odd build problem
This one has had me stumped for over a year and seems really odd and really obscure. When I build my solution, it complains about a missing referenced DLL. When I rebuild it, the problem goes away. Whenever I do a clean this returns, i.e. have to attempt a build twice before it succeeds. This is vague, but if warranted I can give a b...
Preventing a RichTextBox operation from being added to the control's Undo stack
Editing a RichTextBox control's text (more specifically, modifying selection font/color) programmatically seems to be tracked in the control's built in undo stack. Is there a way, short of writing my own undo/redo "manager", to prevent certain actions/operations from being added to the undo stack ? ...
