filenames

I have created a screenshot program and all is working great. The only problem is, I am not sure how I can make it so the screenshots are saved with appending numbers. Example: Screenshot 1, Screenshot 2, Screenshot 3, Screenshot 4, etc. Obviously this could be applied to other files being saved. Any ideas? Thank you. Here is a method I use frequently for this very case. Just pass in a string like "Screenshot" and it will find the lowest available filename in the format of "Screenshot [number]" (or just "Screenshot" if there aren't any already): private string GetUniqueName(string name, string

I'm looking for a way to make sure a string can be used as a file name under iOS. I'm currently in the section of the code that deletes incompatible characters. I'm wondering if I'm doing it right. NSString *filename = @"A file name"; fileName = [fileName stringByTrimmingCharactersInSet: [NSCharacterSet controlCharacterSet]]; fileName = [fileName stringByTrimmingCharactersInSet: [NSCharacterSet newlineCharacterSet]]; I'm also wondering if there's already a method that validates a string as a file name.

How does one work with filenames that end in a period in Python? According to MSDN's site, such filenames are valid in Windows, but whenever I try to create one in Python, it removes the final period. I even tried creating a raw file descriptor with os.open, but it still removes the period. For example, this will create a file simply named ' test ' os.open('test.', os.O_CREAT | os.O_WRONLY, 0777) Edit: Here is the exact quote About spaces and dots in filenames and directories. The limits are in the windows shell -- not in Windows or NT. Using 'bash', you can create files with spaces (or dots),
