I am trying to use the Directory.GetFiles() method to retrieve a list of files of multiple types, such as mp3's and jpg's. I have tried both of the following with no luck:

Directory.GetFiles("C:\path", "*.mp3|*.jpg", SearchOption.AllDirectories);
Directory.GetFiles("C:\path", "*.mp3;*.jpg", SearchOption.AllDirectories);

Is there a way to do this in one call?



For .NET 4.0 and later,

var files = Directory.EnumerateFiles("C:\path", "*.*", SearchOption.AllDirectories)
            .Where(s => s.EndsWith(".mp3") || s.EndsWith(".jpg"));

For earlier versions of .NET,

var files = Directory.GetFiles("C:\path", "*.*", SearchOption.AllDirectories)
            .Where(s => s.EndsWith(".mp3") || s.EndsWith(".jpg"));

edit: Please read the comments. The improvement that Paul Farry suggests, and the memory/performance issue that Christian.K points out are both very important.

Here's an excerpt from my answer to another question.

Unresolved Identifier

If the source of the .cpp file looks like this

enter image description here

Click with the right mouse button on your project.
Check C/C++ Code As...
Run Reparse Project.

enter image description here

If that is not enough.
Go to Project Properties
Fill in the Include input field as described.

enter image description here

Set the include path correct.

I hope that can help you.

I haven't used NetBeans, but Eclipse CDT (C Developer Tools, which includes C++), especially with the latest version, is really quite excellent:

  • Syntax checking and spell checking
  • Syntax highlighting that distinguishes between library calls and your function calls and between local and member variables and is even applied to code that's #ifdef'ed out
  • Macro expansion that can step you through each level of macro application or show the final result even of very complex Boost Preprocessor macros
  • A file and class outline view that updates dynamically to show where you are in a file. (Commercial IDE's I've used fail to do this.)
  • Powerful, flexible Find/Replace and Find in Files features with complete Perl-style regex support. It's also supposed to be able to do a C/C++ Find in Files that can search based on language semantics (e.g., only find references, not declarations), although this sometimes doesn't work for me.
  • Automatic tracking of TODO and other comment tags
  • Mouseover tips that show the exact declaration of a variable or function, including any comments, instead of just where a variable or function is declared. (Again, commercial IDE's I've used fail to do this.)
  • Support via plugins for Subversion, Doxygen, etc.
  • Some refactoring support - rename, extract constant, extract function, a few others
  • Code reformatter, based on user-definable code styles

You'd asked specifically about its editor; the Eclipse editor is good enough that I use it in preference to the commercial IDE for our product whenever I don't need the commercial IDE's forms designer.

Eclipse's debugger integration (using gdb) is tolerable but not great, and its memory usage is high. A few features (like the C/C++ Find in Files) don't work reliably or require reindexing (which is time consuming) for no apparent reason, but the latest version seems more reliable in this regard.

Can someone who's used NetBeans fill in how it compares?

The problem I'm running into is that anytime I try to call FB.login inside a callback to other FB methods, the browser seems to lose track of the origin of execution (the click) and thus will block the popup.

He is not actually “losing track” – it’s a whole different execution context, because the FB methods work asynchronously. The click happened in an execution context that is long gone and finished by the time the callback function is executed.

You could check permissions earlier, on page load. It is not very likely that something about the user’s given permissions changes while he’s on your site, I guess – at least for a “normal” user, who does not try to mess with your app to see how it’ll react. (Although there might be uses cases where this can’t be said with certainty.)

If this results in the info that a necessary permission is missing – then call FB.login on the button click asking for this permission. In the FB.login callback, you can check the permissions again, if you want to be sure – if the permission is still not given then, then I’d suggest alerting the user to that fact, maybe telling him again why it’s necessary – and than he’ll have to click the button that starts the whole action again.

If permissions are alright, then you can make your API call to actually make a post. And to be really really sure and on the safe side … in that API call’s callback you can check for success or errors again, and if there’s an error find out if it was due to missing permissions – if so, back to square one, telling the user permission is necessary and have him start the whole thing over again, by clicking the button …
