It's a command-line tool which takes inputs from the command line, and creates a file on disk, let's say an image file I want to use this within another application, by running util.exe. However it needs to be synchronous so the file is known to exist when processing contin...
I have some code in a library which has to internally work with wstring, that's all nice and fine. But it's called with a TCHAR string parameter, from both unicode and non-unicode projects, and I'm having trouble finding a neat conversion for both cases. I see some ATL conversions and so on but can't see the right way, without defining ...
I have a visual studio 2003 project that uses a custom build step to create a pair of .h and .cpp files. The .h and .cpp files are in the project as is a .proto file that has the custom build step. The problem is that although the .h and cpp files are generated whenever the .proto file is changed other cpp files that depend on the .h fil...

I'm just testing out some basic networking code written in Visual C++. I have a client app and a server app that don't do anything fancy, since I'm just testing - basically, the client sends ASCII-encoded strings to the server and the server sends it back all in caps. Everything works fine when I run both programs on my computer, IF I s...

I plan on using the following setup: Site Object: This is the reason the ipc is needed. It will be ...
Is there an efficient way that doesn't require too much fiddling (I can cope with a bit) to get version control working across > 1 environments? By that, I mean multiple IDEs; I am developing on VS2010 at home, but I'd like to work on the project at university with my laptop. My laptop is running Debian and I'm open to suggestion for wha...

Hello, please help me, I have a strange problem which i can't sort out in any way. Premise: I'm using visual c++ 2005 on windows 7 x64, and I'm sure that my code isn't fatally flawed because with g++ under Linux it runs nicely. I am developing an application which uses a static library also developed by me. In the link phase of the a...
What is the difference between Start Debugging (F5) and Start without Debugging (Ctrl-F5) when the code is compiled in Release mode? I am seeing that Ctrl-F5 is 10x faster than F5 for some C++ code. If I am not wrong, the debugger is attached to the executing process for F5 and it is not for Ctrl-F5. Since this is Release mode, the comp...
