deleting a file in use

Ofori Boadu

I have developed an application that takes a photo. I have a fixed path that the photos are saved to. I am able to save just one and after that unless I restart the whole application I am not able to save to overwrite the file because it sees the file as being in use. Any idea how I can overwrite or delete file in use?

It sounds like the actual issue is that you're not actually closing the file when you're done with it.

You probably are not closing the file you previously opened for writing. If you are using the StreamWriter to write the contents, make sure you call Dispose after you're done with it. Or wrap it in a "using" block like

using (StreamWriter writer = new StreamWriter(...))
{
writer.blah();
}

yeah, what happens it I add other things like signature and name to the photo and same them as one image,I don't need to close the program after the process is complete. I have to be doing for a lot of photos.

Hi, there may be two issues: 1. Most ways to load an image keep the image file open as long as the Image object is not Disposed() off. The only exception I am aware of is when reading an image through Image.FromStream() Remedy: use FromStream() or make sure you call Dispose(). remark: I don't think it is sufficient to Dispose() of a PictureBox if it is the only thing refering to the Image that got loaded from your file. 2. When a file, any file, is freshly written chances are some other utility is investigating it, prohibiting you from immediately renaming, deleting or overwriting it; candidate utilities are abything that works in the background on new files, such as file system indexers, and ativirus tools. Remedy: retry a couple of times, 1 second apart. :)
