ioexception

After providing some answers here, and reading some comments, it would seem that, in practice IOException is never thrown on close for file I/O. Are there any cases in which calling close on a Stream/Reader/Writer actually throws an IOException? If an exception is actually thrown, how should it be dealt with? For files, you may not see IOException thrown often on close(), but you'll definitely see it for non-File I/O like closing sockets to the network. Here's an example of a Java bug where closing a UDP socket eventually caused an IOException to be thrown. TofuBeer I have found two cases:

java.io.IOException seems to be the most common type of exception, coincidentally, it seems to also be the most ambiguous. I keep seeing the throws IOException whenever writing with sockets, files, &c. I've never actually had one fired on me, however, so I'm wondering what it is that is supposed to fire the exception. The documentation isn't very helpful in explaining what's going on: Signals that an I/O exception of some sort has occurred. This class is the general class of exceptions produced by failed or interrupted I/O operations. Can someone please explain some instances where an

How can I check if IOException is a "Not enough disk space" exception type? At the moment I check to see if the message matches something like "Not enough disk space", but I know that this won't work if the OS language is not English. Justin You need to check the HResult and test against ERROR_DISK_FULL (0x70) and ERROR_HANDLE_DISK_FULL (0x27) , which can be converted to HResults by OR 'ing with 0x80070000 . For .Net Framework 4.5 and above, you can use the Exception.HResult property: static bool IsDiskFull(Exception ex) { const int HR_ERROR_HANDLE_DISK_FULL = unchecked((int)0x80070027); const

I am displaying some image in my wpf app using following code: <Image Source="{Binding Path=TemplateImagePath, Mode=TwoWay}" Grid.Row="3" Grid.Column="2" Width="400" Height="200"/> and setting it's binding property inside code behind's constructor by navigating through some directory, below is the code: DirectoryInfo Dir = new DirectoryInfo(@"D:/Template"); if (Dir.Exists) { if (Dir.GetFiles().Count() > 0) { foreach (FileInfo item in Dir.GetFiles()) { TemplateImagePath = item.FullName; } } } but if user upload some other image then I need to delete this old image which is I am doing in the

This code used to work. Then, maybe I changed something, somewhere (or if I know Android right, an update introduced a bug in the media player). It stopped working on some devices! Especially my Nexus S (2.3.6). The file test.m4a (17 775 201 bytes) was downloaded by the app. To verify its integrity, I copied it to the SD and played it on my PC. No problem! Also binary-compared it with the original file, and it matched 100%. try { _mediaPlayer = new MediaPlayer(); _mediaPlayer.setOnCompletionListener(this); _mediaPlayer.setOnPreparedListener(this); _mediaPlayer.setOnSeekCompleteListener(this);

I am newbie to android and this is my first project on android. I am struggling with "authentication" problem for more than a day. I tried several options but none of them worked. Basically, I want to call a REST API and get response. I am sure that there is no problem in API as I use the same one in another iOS application. I pass authorization header but still authentication no found message is shown. I found few question on stackoverflow related to this, but some of them did not work and some does not make sense to me. I get status code 401 . I know this means either no authentication
