I have many processes reading a file stored on a network share. Originally I was only able to have one process read the file, all the others would throw exceptions. I implemented the following code to deal with that: using (StreamReader fileStreamReader = new StreamReader(File.Open(path, FileMode.Open, FileAccess.Read, FileShare.Read)))...
Code: String tempFile = Path.GetTempFileName(), read = ""; TextReader pending = new StreamReader("c:\\pending.txt"); TextWriter temp = new StreamWriter(tempFile); read = pending.ReadLine(); while ((read = pending.ReadLine()) != null) { temp.WriteLine(read); } ...
Hi, I am currently writing a plugin in C++. For my functionality I ask the API to save out a file. The API gives me a return value when the file is written... or so it seemd.

I could use some advice. I'm building a website in which the general user needs to be able to transfer files to the site administrator. It could be done one of two ways: 1] Some kind of web based interface - PHP perhaps - to send files to the FTP. I've done some Googling but have yet to come up with anything concrete that works.

How can I add files starting with dot (hidden files) in git repo? Git seems to always ignore those. When I type "git add .", dotfiles in GIT_DIR are added, but not from subdirectories. On the other hand, "git add subdir/.dotfile" won't work. I tried "git add -f" and putting "!.*" in GIT_DIR/.git/info/exclude. No luck. ...
