I need to count and check how much of some images is placed in folder od web server.
Example- images get names from user_id, and on example I have user_id 27, and my images are:
27_1.jpg, 27_2.jpg, 27_3.jpg, ...
How to check and write to database this thing?
Thanks
Once you know your path you can use IO.Directory.GetFiles() method.
IO.Directory.GetFiles("\translated\path","27_*.jpg").Count()
will give you what you're looking for.
Using the System.IO namespace, you can do something like this
public File[] GetUserFiles(int userId)
{
List<File> files = new List<File>();
DirectoryInfo di = new DirectoryInfo(#"c:\folderyoulookingfor");
foreach(File f in di.GetFiles())
{
if(f.ToString().StartsWith(userId.ToString()))
files.Add(f);
}
return file.ToArray();
}

I try to eneable audio in my Xamarin.Forms application. I want to have the audio files in a Subfolderof the Assetsfolder like this Assets/Subfolder/Audio.mp3
I have found a plugin SimpleAudioPlayer which provide an example.
The following code works like provided.
var player = Plugin.SimpleAudioPlayer.CrossSimpleAudioPlayer.Current;
player.Load("Audio.mp3");
Now I want to place the audio file in a subfolder and I tried to call
player.Load("Subfolder/Audio.mp3");
But I get an Java.IO.FileNotFoundException
I looked then into the implementation of the Load function and I fould the following code
public bool Load(string fileName)
{
player.Reset();
AssetFileDescriptor afd = Android.App.Application.Context.Assets.OpenFd(fileName);
player?.SetDataSource(afd.FileDescriptor, afd.StartOffset, afd.Length);
return PreparePlayer();
}
where the filename is pasted to the Assets.OpenFd() function. which returns an AndroidFileDesriptor
The documentation does not really provide any information from Microsoft and from the Android site.
My questions are
How can I receive the file from the subfolder in Android Assets?
What can I paste into the Assets.OpenFd() function (subfolders etc)?
I would appreciate any advice, since after a long time trying to resolve it I don't really have an idea.
According to the docs of the package, you won't be able to do just that because you have to use player.Load(GetStreamFromFile("mysound.wav")); where GetStreamFromFile is basically
Stream GetStreamFromFile(string filename)
{
var assembly = typeof(App).GetTypeInfo().Assembly;
var stream = assembly.GetManifestResourceStream("App." + filename);
// Obviously App in the line above should be replaced with your app
return stream;
}
And secondly you have to player.Load(GetStreamFromFile("Subfolder.mysound.wav")); where Subfolder is the name of your subfolder.
I need to create form to upload file from client side to server in AX 2012 R3 using X++.
Can some one give me link / example regarding this issue?
I try to search and find that I can use class SysFileStoreManager, but still confused how to use it.
You can find example use of SysFileStoreManager using the Cross-reference Tool. I find it a bit bloated.
You can do this:
static client container getPackedFileClient(FileName _fileNameClient)
{
BinData binData = new BinData();
binData.loadFile(_fileNameClient);
return binData.getData();
}
This is the SysFileStoreManager.getPackedFileClient method, but without the protected keyword.
To save the file:
static server container saveFileToServer(container _packedFile, Filename _filename)
{
#File
BinData b = new BinData();
b.setData(_packedFile);
new FileIOPermission(_filename, #IO_WRITE).assert();
b.saveFile(_filename);
}
This is SysFileStoreManager.copyFileToClient_Client adapted for general use. You can the call the methods in sequence:
saveFileToServer(getPackedFileClient(clienFileName), serverFileName);
The file content is transferred from client to server using a container.
In a ASP.NET MVC 4 project, I'd like to reference a versioned script file like this:
// Just some pseudo-code:
<script src="#Latest("~/Scripts/jquery-{0}.min.js")"></script>
// Resolves to the currently referenced script file
<script src="/Scripts/jquery-1.10.2.min.js"></script>
so that when a new Script version is updated via NuGet, the reference is updated automatically. I know of the bundling-and-minification feature, but it's just to much. I just want the little part which resolves the wildcards. My files are already minified, and also I don't want the bundles.
Do you have some smart ideas how to solve this?
Even though it's a little over kill to use the Bundling in MVC, but I think that will be your best bet. It's already been done and proven so why spend more time to write some proprietary code.
That being said, if you want a simple sample of what you can do, then you can try the following.
public static class Util
{
private const string _scriptFolder = "Scripts";
public static string GetScripts(string expression)
{
var path = HttpRuntime.AppDomainAppPath;
var files = Directory.GetFiles(path + _scriptFolder).Select(x => Path.GetFileName(x)).ToList();
string script = string.Empty;
expression = expression.Replace(".", #"\.").Replace("{0}", "(\\d+\\.?)+");
Regex r = new Regex(#expression, RegexOptions.IgnoreCase);
foreach (var f in files)
{
Match m = r.Match(f);
while (m.Success)
{
script = m.Captures[0].ToString();
m = m.NextMatch();
}
}
return script;
}
}
This will return you the last match in your Scripts director or it will return empty string.
Using this call
#Html.Raw(MvcApplication1.Util.GetScripts("jquery-{0}.min.js"))
Will get you this result if 1.8.2 is the last file that matched your string.
jquery-1.8.2.min.js
Hope this will help you get started.

In Orchard, each site (whether or not you enable multitenancy) seems to have it's own Folder within Media (main file folder for Orchard). I want to get the entire filesize of a current site (ergo, the folder under Media).
I've digged into the Framework and got into FileSystemStorageProvider which seems to be promising with the FileSystemStorageFolder class and GetSize() method.
However, I was wondering if anyone else checked this out before I go into experimenting with that class.
Any piece of information or advise would be highly apreciated. Thanks!
Didn't really find an easy way to do it but copied mostly from the Orchard framework. You will need the following:
private FileSystemStorageProvider _filesystemProvider;
private ShellSettings _settings;
And then you need to define the Site Storage Path:
var mediaPath = HostingEnvironment.IsHosted
? HostingEnvironment.MapPath("~/Media/") ?? ""
: Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Media");
storagePath = Path.Combine(mediaPath, _settings.Name);
Finally, here is my function to compute the storage for a specific folder (in this case, the tenant's/site's root media folder):
public double GetSiteStorage()
{
var folders = _filesystemProvider.ListFolders(storagePath);
long totalSize = 0;
foreach (var folder in folders)
{
totalSize += folder.GetSize();
}
return (totalSize / 1024 / 1024);
}
This returns a double for the MB used. Hope this helps someone :)
I am making an app that runs in the background, and starts on device boot.
I have read the docs, and have the SQLiteDemo files from RIM, and I am using them to try create a database on my SD Card in the simulator.
Unfortunately, I am getting this error:
DatabasePathException:Invalid path name. Path does not contains a proper root list. See FileSystemRegistry class for details.
Here's my code:
public static Database storeDB;
public static final String DATABASE_NAME = "testDB";
private String DATABASE_LOCATION = "file:///SDCard/Databases/MyDBFolder/";
public static URI dbURI;
dbURI = URI.create(DATABASE_LOCATION+DATABASE_NAME);
storeDB = DatabaseFactory.openOrCreate(dbURI);
I took out a try/catch for URI.create and DatabaseFactory.openOrCreate for the purposes of this post.
So, can anyone tell me why I can't create a database on my simulator?
If I load it up and go into media, I can create a folder manually. The SD card is pointing to a folder on my hard drive, and if I create a folder in there, it is shown on the simulator too, so I can create folders, just not programatically.
Also, I have tried this from the developer docs:
// Determine if an SDCard is present
boolean sdCardPresent = false;
String root = null;
Enumeration enum = FileSystemRegistry.listRoots();
while (enum.hasMoreElements())
{
root = (String)enum.nextElement();
System.err.println("root="+root);
if(root.equalsIgnoreCase("sdcard/"))
{
sdCardPresent = true;
}
}
But it only picks up store/ and never sdcard/.
Can anyone help?
Thanks.
FYI,
I think I resolved this.
The problem was I was trying to write to storage during boot-up, but the storage wasn't ready. Once the device/simulator was loaded, and a few of my listeners were triggered, the DB was created.
