阅读更多关于 How can I let users access the internal storage directory of my app?

问题 My app stores files in its internal storage directory (/Android/data/com.mycompany.myapp/files, as returned by getFilesDir()), and I would like to allow users to access those files directly from a file management app on their mobile device or the Android File Transfer desktop appplication. The Storage Options developer guide says: By default, files saved to the internal storage are private to your application and other applications cannot access them (nor can the user). "By default" implies

How do I give PHP write access to a directory?

阅读更多关于 How do I give PHP write access to a directory?

I'm trying to use PHP to create a file, but it isn't working. I am assuming this is because it doesn't have write access (it's always been the problem before). I tried to test if this was the problem by making the folder chmod 0777, but that just ended up making every script in that directory return a 500 error message until I changed it back. How do I give PHP write access to my file system so it can a create a file? Edit: It is hosted on Hostgator shared hosting using Apache. Edit 2: Someone asked for the code: The code is a GD image script. I know the rest of it works as previously I was

Storing file permissions in Subversion repository

阅读更多关于 Storing file permissions in Subversion repository

问题 How do you store file permissions in a repository? A few files need to be read-only to stop a third party program from trashing it but after checking out of the repository they are set to read-write. I looked on google and found a blog post from 2005 that states that Subversion doesn't store file-permissions. There are patches and hook-scripts listed (only one url still exists). Three years later does Subversion still not store file permissions and are hooks the only way to go about this? (I

I am using R 2.13.0 with windows 7, after giving my user full privileges to the R folder (as described here ). This allows me to install new packages just fine.

It will work ( http://vivekthangaswamy.blogspot.com/2009/07/aspnet-website-cannot-read.html ) What do I add to my web.config file though? I've never had to edit it before.
