We are taking input from a text file. Every line is split in strings at white spaces, so we can further classify the elements. Making the string the problem is, that I also want to read string literals (e.g. "Thank you") as they are without splitting and comments too (both // and /* ....*/). Is there any way I can do this? ...
How do you maintain the #include statements in your C or C++ project? It seems almost inevitable that eventually the set of include statements in a file is either insufficient (but happens to work because of the current state of the project) or includes stuff that is no longer needed. Have you created any tools to spot or rectify proble...
Our application is occasionally hanging while it saves, where the core data raw file is being left locked (perhaps by our spotlight importer). We've verified that it's at a low-level file level, not at the core data level. What I'm trying to do is figure out how to monitor the application while it's running so if I get this hang, I can...

I need to write a file format that writes out data to a file and can read it back. It should be able to read the data back fairly fast, which should involve blitting a large block of data into a std::vector (since their storage is always implemented contiguously). However, when writing the file, I have no idea how to enforce constraint...

I want to check if a file path is in a given directory (or one of its subdirectories), from PowerShell. Right now I'm doing: $file.StartsWith( $directory, [StringComparison]::InvariantCultureIgnoreCase ) but I'm sure there are better ways. I could do take $file.Directory and iterate over all .Parents, but I was hoping for something...
I want to upload a file from a web application. The web application calls web services to access .NET classes, but it's not a .NET application itself. What I want to do is this: upload a file from the web application, and call a separate .NET page to process and handle the uploaded file. It would be easy to do this if I used a php sc...
I am looking for an efficient way to create a file whose size is unknown but can range from mb's to gb's and fill its content randomly. I may write first 200 bytes than jump to the end and write last 200 bytes and move to the middle and write there. Is RandomAccessFile efficient for doing this or are there any alternatives better suited ...

When I move a file in git using git-mv the status shows that the file has been renamed and even if I alter some portions it still considers to be almost the same thing (which is good because it lets me follow the history of it). When I copy a file the original file has some history I'd like to associate with the new copy. I have tried...
