I am facing a problem.My Environment is:
OSX 10.10.5 YOsemite
xocde 7.2
I want to add a new video file(.mp4) in my ios simulator. i add this in
/Users/mynane/Library/Developer/CoreSimulator/Devices/mydevice/data/Media/DCIM/100APPLE
after adding this, when i relaunch my simulator, than the added video is not shown. It shows only the previously added default images.
I also delete
photoData
but same result.
how i can solve this?
Please paste you video file or any file which you want to preload with ios simulator in below path
String str = /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/Library/CoreSimulator/Profiles/Runtimes/iOS 9.2.simruntime/Contents/Resources/SampleContent/Media/DCIM/100APPLE/
or you can use below java code which will copy your desired file into the simuator location.
public void preloadFiletoSimulator(String filename){
try {
File dest = new File(str);
String name = AppConstant.RESOURCE_DIR+filename;
File source = new File(name);
FileUtils.copyFileToDirectory(source, dest);
} catch (IOException e) {
e.printStackTrace();
}
}

I am trying to programmatically create an ePub file. I am following this tutorial. The tutorial says to "make the .epub container that all these files go in" by:
Create an empty .zip file with whatever name you like (See notes below for detailed instructions on how to do this.)
Copy the mimetype file into the zip file (don't use compression on this file)
Copy the rest of the files and folders mentioned above into the zip file *
Re-name the .zip extension to .epub
These are the last few steps of the process. I have all the files that need to go into the zip ready. I know the files work because I used a third party program (eCanCrusherMac.1.2.1) to do these finals steps and the product it creates is an ePub file that loads in the Books eReader (made by Apple).
I used the below code to zip the desired directory. I found this code on here Stack Overflow
func zip(itemAtURL itemURL: URL, in destinationFolderURL: URL, zipName: String) throws {
var error: NSError?
var internalError: NSError?
NSFileCoordinator().coordinate(readingItemAt: itemURL, options: [.forUploading], error: &error) { (zipUrl) in
// zipUrl points to the zip file created by the coordinator
// zipUrl is valid only until the end of this block, so we move the file to a temporary folder
let finalUrl = destinationFolderURL.appendingPathComponent(zipName)
do {
try FileManager.default.moveItem(at: zipUrl, to: finalUrl)
} catch let localError {
internalError = localError as NSError
}
}
if let error = error {
throw error
}
if let internalError = internalError {
throw internalError
}
}
I took the file this function gives me, made sure it had the epub extension and tried to open it using the Books app but it fails to load. The code produces a zip file that I can interact with normally in Finder so I know the function works.
I believe the issue is with the "mimetype" file getting compressed. I have taken a valid ePub, changed the file's extension to zip, unzipped it and then rezipped it using Finder and tried to open it again with no other changes and it doesn't work. As you can see in the instructions from the tutorial at the top of this post the "mimetype" file can't be compressed.
This is a Swift app on Mac.
I looked into the different NSFileCoordinator.ReadingOptions and NSFileCoordinator.WritingOptions and searched on Stack Overflow and elsewhere online but I can't find anything on how to create a zip file in Swift without compressing a file contained in the zip file.
I was able to get the ePub to open using ZIPFoundation:
try FileManager.default.zipItem(
at: bookURL,
to: ePubURL,
shouldKeepParent: false,
compressionMethod: .none,
progress: nil
)
I try to make a spigot plugin that can detect if nobody is on the server. I need this for a timer, if nobody is on the server, it should stop the timer and save the time of the timer in a text file. Is there any way I can do this with a plugin.
Thanks for every help, Aaron.
How to create text files:
try {
File file = new File(Yourplugin.getPlugin(YourPlugin.class).getDataFolder().getPath(), "filename.txt");
file.getParentFile().mkdirs();
file.createNewFile();
} catch (IOException exception){
System.out.println(exception.toString());
}
How to read from text files:
File file = new File(YourPlugin.getPlugin(Yourplugin.class).getDataFolder().getPath(), "filename.txt");
BufferedReader br = new BufferedReader(new FileReader(file));
String line = br.readline(); //can be null, if nothing is in file
How to write to Files:
File file = new File(YourPlugin.getPlugin(Yourplugin.class).getDataFolder().getPath(), "filename.txt");
BufferedWriter wr = new BufferedWriter(new FileWriter(file));
br.write("yourtime");
You should make a try catch construction in every example like in the first one.
See Bukkit#getOnlinePlayers(); and check if it is empty. You can check when a player disconnects from the server, or you can do a repeating scheduled task.
To save the timer in a yml file, use YamlConfiguration. See here for more details : https://www.spigotmc.org/wiki/config-files/#creating-the-file
If you need more help (and a quicker answer, probably) you can add me on discord: Pierre#7757. I'll edit this comment if we find any good solution.
I have a text file that I will be reading and writing to. I have gotten the code to read successfully, but am unable to write to the text file again. I want to overwrite everything (not amend).
if let dir : NSString = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.AllDomainsMask, true).first {
let path = dir.stringByAppendingPathComponent("airports.txt")
var strTextToWrite:String = String()
strTextToWrite = "Test"
do {
try strTextToWrite.writeToFile(path, atomically: false, encoding: NSUTF8StringEncoding)
}
catch { print("Error") }
}
The above code doesn't throw an error (i.e. the word 'Error' isn't printed as per my catch code), but the text file remains unedited, retaining the value it had before the code was run.
The text file is contained inside the X-Code project as shown below:
I'm at a real loss here, I don't understand why the code isn't working. I have confirmed that it is being run (by printing the value of strTextToWrite before and after the do statement, and it is definitely running through the do block of code because it isn't being caught by the catch block. The only thing I can think of is that the code is pointing at the wrong file (but the file name is correct, as you can verify with the screenshot above).
What am I doing wrong? Thanks in advance.
You are looking at 2 different files: the one you write to is ~/Documents/airport.txt while the one you see (and check) in Xcode is located in your project folder. To see the update, you need to reference the file in Xcode, not make a copy of it.
Right click airport.txt in your Project Navigator and click Delete > Move to Trash
Go to ~/Documents/airport.csv and drag it into your Xcode project. Do not add it to any target and unselect "Copy Items if Necessary"
You now have created a link to the file.
Modifying files in your bundle is generally a bad idea. If you need a place to output a temporary file, use the app's subfolder under ~/Application Support or the system's temp folder.
I have developed a C# application, in the application the users choose a photo for each record. However the user should also be able to change the pre-selected photo with a newer one. When the user changes the photo the application first deletes the old photo from the application directory then copies the new photo, but when it does that the application gives an exception because the file is used by the application so it cannot be deleted while the application is running. Does any one have a clue how to sort this out? I appreciate your help
This is the exception
The process cannot access the file
'D:\My
Projects\Hawkar'sProject\Software\Application\bin\Debug\Photos\John
Smith.png' because it is being used by
another process.
//defining a string where contains the file source path
string fileSource = Open.FileName;
//defining a string where it contains the file name
string fileName = personNameTextBox.Text + ".png" ;
//defining a string which specifies the directory of the destination file
string fileDest = dir + #"\Photos\" + fileName;
if (File.Exists(fileDest))
{
File.Delete(fileDest);
//this is a picturebox for showing the images
pbxPersonal.Image = Image.FromFile(dir + #"\Photos\" + "No Image.gif");
File.Copy(fileSource, fileDest);
}
else
{
File.Copy(fileSource, fileDest);
}
imageIDTextBox.Text = fileDest;
First of all, you code is not good.
The new image is only copied if there is currently no image (else).
But if there is an old image, you only delete this image, but never copy the newer one (if).
The code should better look like this:
if (File.Exists(fileDest))
{
File.Delete(fileDest);
}
File.Copy(fileSource, fileDest);
imageIDTextBox.Text = fileDest;
This code should work, but if you are getting an exception that the file is already in use, you should check "where" you use the file. Perhaps you are reading the file at program start. Check all parts of your program you are accessing these user files if there are some handles open.
Thanks a lot for your help and sorry for the mistake in the code I just saw it, my original code is just like as you have written but I don't know maybe when I posted accidentally I've put like this. when the application runs there is a picturebox which the image of each record is shown, that is why the application is giving an exception when I want to change the picture because it has been used once by the picturebox , however I've also tried to load another picture to the picture box before deleting the original one but still the same. I've modified the above could if you want to examine it
No matter what I try (build -> content, NSUrl, filename) I get a 'null exception': file not found when I try to play a .caf sound file in monotouch.
//var path = NSBundle.MainBundle.PathForResource("MatchGame", "caf");
//var gameSong = SystemSound.FromFile( new NSUrl(path, false));
var gameSong = SystemSound.FromFile("MatchGame.caf");
gameSong.PlaySystemSound();
I also try combinations using the folder name "images/MatchGame.caf" and moving MatchGame.caf into the root folder.
What am I missing? Thanks a lot.
Here is a link to a video of adding the sound in monotouch. http://www.screencast.com/t/MmE0ZmFh What is wrong?
Bryan,
From looking at your screencast - you are trying to play a mp3 file and not a caf file. Mp3 files are encoded differently and will not play with the SystemSound class that's there (I can't remember if you can do this in Obj-C or not.)
You'll want to use the AVFoundation Namespace and AVAudioPlayer class.
using Monotouch.AVFoundation;
var mediaFile = NSUrl.FromFilename("myMp3.mp3");
var audioPlayer = AVAudioPlayer.FromUrl(mediaFile);
audioPlayer.FinishedPlaying += delegate { audioPlayer.Dispose(); };
audioPlayer.Play();
You might need to tweak the code above - I don't have MonoDevelop to hand but that should help you a little further.
Cheers,
ChrisNTR
You need the first line:
var path = NSBundle.MainBundle.PathForResource("MatchGame", "caf");
Then make sure that your audio file is included in the application by making sure that your CAF file is flagged as "Content" in the Properties pane, otherwise the file is not copied to the resulting application package (your .app)
You can follow the steps documented here (they are for images, but apply the same to audio files):
http://wiki.monotouch.net/HowTo/Images/Add_an_Image_to_your_Project
Additionally, this is a good resource for where you should store files:
