I'm creating a pdf like this:
WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage.load(new java.io.File(inputfilepath));
OutputStream os = new java.io.FileOutputStream(outputFilePath);
Docx4J.toPDF(wordMLPackage, os);
It works fine.
After the pdf created, a hf.fo file appears in the doot directory. Why? How can I change the path of this file?
if (log.isDebugEnabled()) {
foSettings.setFoDumpFile(new java.io.File(System.getProperty("user.dir") + "/hf.fo"));
}
Turn off DEBUG level logging for org.docx4j.convert.out.fo.FOPAreaTreeHelper

I am getting UnauthorizedAccessException while copying the file to a directory, inside the wwwroot. However Directory.CreateDirectory(uploadFolderPath); creates the folder.
The code I am using to create the folder and copy the files is shown below.
public string UploadPdfFile(IFormFile file, string folderName)
{
if (file == null || file.Length == 0)
{
return string.Empty;
}
// Define the file path
string uploadFolderPath = Path.Combine(_env.WebRootPath, #"uploads\books", $"{folderName}");
if (!Directory.Exists(uploadFolderPath))
Directory.CreateDirectory(uploadFolderPath);
// Save the file to the drive
using (var stream = new FileStream(uploadFolderPath, FileMode.Create))
{
file.CopyTo(stream);
}
return uploadFolderPath;
}
The error says:
UnauthorizedAccessException: Access to the path 'D:\Project\XX-Pedia\XX-Pedia\wwwroot\Uploads\Books\c1' is denied.
What is the solution for this?
I am running the visual studio in administrative mode.
This is strange because the code can create the folder but couldn't copy the files to the folder.
Turns out that I was missing the actual filename component...
string uploadFolderPath = Path.Combine(_env.WebRootPath, #"uploads\books", $"{folderName}");
if (!Directory.Exists(uploadFolderPath))
Directory.CreateDirectory(uploadFolderPath);
//added this line
string filepath = Path.Combine(uploadFolderPath, file.FileName);
// Save the file to the drive
using (var stream = new FileStream(filepath, FileMode.Create))
{
file.CopyTo(stream);
}
I have an application where I need to show the .pptx and .pdf files. For pdf files I am using react-native-pdf and file is opening fine in my App but when it comes to .pptx files we have 2 libraries:
1. https://www.npmjs.com/package/react-native-doc-viewer
2. https://www.npmjs.com/package/react-native-file-viewer
react-native-doc-viewer is not being actively maintained and a lot of issues :(
But both of them were giving a prompt to select an app like Wps Office or Microsoft apps but they were not opening as Pdf files opened in my app. Whats the reason behind this? We cannot open pptx file in our app?
I read the react-native-doc-viewer android native code. it is actually is to download a doc not to view it. the following is the code:
#ReactMethod
public void openDoc(ReadableArray args, Callback callback) {
final ReadableMap arg_object = args.getMap(0);
try {
if (arg_object.getString("url") != null && arg_object.getString("fileName") != null) {
// parameter parsing
final String url = arg_object.getString("url");
final String fileName =arg_object.getString("fileName");
final String fileType =arg_object.getString("fileType");
final Boolean cache =arg_object.getBoolean("cache");
final byte[] bytesData = new byte[0];
// Begin the Download Task
new FileDownloaderAsyncTask(callback, url, cache, fileName, fileType, bytesData).execute();
}else{
callback.invoke(false);
}
} catch (Exception e) {
callback.invoke(e.getMessage());
}
}
it uses FileDownloaderAsyncTask to download files. if you are familiar with it.
if you want to show excels, Docx, you can use the google doc line convert it to Html, then in the webView to show it. the format like it: https://docs.google.com/gview?embedded=true&url=[doc address], the same effect as ios.
I want to edit a file "application.properties" inside "imp" directory inside a zip "archive.zip". I'm using Truezip for this. I tried using both TFileOutputStream and TFileWriter. But both of them are creating a tmp file, but not editing the actual file in zip. The actual file in zip still remains same. Below are my code samples:
1. Using TFileOutputStream:
OutputStream out = new TFileOutputStream("C:\sample\archive.zip\imp\application.properties");
// Loading properties code here
properties.store(out, null);
out.close();
Using TFileWriter:
File entry = new TFile("C:\sample\archive.zip\imp\application.properties");
Writer writer = new TFileWriter(entry);
try {
writer.write("wish.world=Hello world\n");
} finally {
writer.close();
}
Kindly help.
You need to call TVFS.umount() to persist your changes.
I use Xamarin Android. I have a PDF File stored in Assets folder from Xamarin Android.
I want to share this file in WhatsApp, but I receive the message:
The file you picked was not a document.
I tried two ways:
This is the first way
var SendButton = FindViewById<Button>(Resource.Id.SendButton);
SendButton.Click += (s, e) =>
{
////Create a new file in the exteranl storage and copy the file from assets folder to external storage folder
Java.IO.File dstFile = new Java.IO.File(Environment.ExternalStorageDirectory.Path + "/my-pdf-File--2017.pdf");
dstFile.CreateNewFile();
var inputStream = new FileInputStream(Assets.OpenFd("my-pdf-File--2017.pdf").FileDescriptor);
var outputStream = new FileOutputStream(dstFile);
CopyFile(inputStream, outputStream);
//to let system scan the audio file and detect it
Intent intent = new Intent(Intent.ActionMediaScannerScanFile);
intent.SetData(Uri.FromFile(dstFile));
this.SendBroadcast(intent);
//share the Uri of the file
var sharingIntent = new Intent();
sharingIntent.SetAction(Intent.ActionSend);
sharingIntent.PutExtra(Intent.ExtraStream, Uri.FromFile(dstFile));
sharingIntent.SetType("application/pdf");
this.StartActivity(Intent.CreateChooser(sharingIntent, "#string/QuotationShare"));
};
This is the second
//Other way
var SendButton2 = FindViewById<Button>(Resource.Id.SendButton2);
SendButton2.Click += (s, e) =>
{
Intent intent = new Intent(Intent.ActionSend);
intent.SetType("application/pdf");
Uri uri = Uri.Parse(Environment.ExternalStorageDirectory.Path + "/my-pdf-File--2017.pdf");
intent.PutExtra(Intent.ExtraStream, uri);
try
{
StartActivity(Intent.CreateChooser(intent, "Share PDF file"));
}
catch (System.Exception ex)
{
Toast.MakeText(this, "Error: Cannot open or share created PDF report. " + ex.Message, ToastLength.Short).Show();
}
};
In other way, when I share via email, the PDF file is sent empty (corrupt file)
What can I do?
The solution is copying de .pdf file from assets folder to a local storage. Then We able to share de file.
First copy the file:
string fileName = "my-pdf-File--2017.pdf";
var localFolder = Android.OS.Environment.ExternalStorageDirectory.AbsolutePath;
var MyFilePath = System.IO.Path.Combine(localFolder, fileName);
using (var streamReader = new StreamReader(Assets.Open(fileName)))
{
using (var memstream = new MemoryStream())
{
streamReader.BaseStream.CopyTo(memstream);
var bytes = memstream.ToArray();
//write to local storage
System.IO.File.WriteAllBytes(MyFilePath, bytes);
MyFilePath = $"file://{localFolder}/{fileName}";
}
}
Then share the file, from local storage:
var fileUri = Android.Net.Uri.Parse(MyFilePath);
var intent = new Intent();
intent.SetFlags(ActivityFlags.ClearTop);
intent.SetFlags(ActivityFlags.NewTask);
intent.SetAction(Intent.ActionSend);
intent.SetType("*/*");
intent.PutExtra(Intent.ExtraStream, fileUri);
intent.AddFlags(ActivityFlags.GrantReadUriPermission);
var chooserIntent = Intent.CreateChooser(intent, title);
chooserIntent.SetFlags(ActivityFlags.ClearTop);
chooserIntent.SetFlags(ActivityFlags.NewTask);
Android.App.Application.Context.StartActivity(chooserIntent);
the file you picked was not a document
I had this issue when I trying to share a .pdf file via WhatsApp from assets folder, but it gives me the same error as your question :
the file you picked was not a document
Finally I got a solution that copy the .pdf file in assets folder to Download folder, it works fine :
var pathFile = Android.OS.Environment.GetExternalStoragePublicDirectory(Android.OS.Environment.DirectoryDownloads);
Java.IO.File dstFile = new Java.IO.File(pathFile.AbsolutePath + "/my-pdf-File--2017.pdf");
Effect like this.
The following code is great for renaming a file if you know the file is in applicationStorageDirectory
var sourceFile:File = File.applicationStorageDirectory;
sourceFile = sourceFile.resolvePath("Kalimba.snd");
var destination:File = File.applicationStorageDirectory;
destination = destination.resolvePath("test.snd");
try
{
sourceFile.moveTo(destination, true);
}
catch (error:Error)
{
trace("Error:" + error.message);
}
How do you set the sourceFile if all you have is the file's native path in a string? Like this:
D:\Software\files\testList.db
This throws errors:
sourceFile = sourceFile.resolvePath("D:\Software\files\testList.db");
The idea is I want to rename a file I had previously loaded into a var. I figured I'd extract the native path to a String var, null the File var (so the OS doesn't tell me it can't be renamed while the file is opened in flash), resolve that nativePath as the sourceFile, and use moveTo to rename the file on the hard drive.
Cheers for taking a look.
EDIT:
I've set up a test AIR app with only the following in it:
import flash.events.*;
import flash.filesystem.*;
var original = File.documentsDirectory;
original = original.resolvePath("D:\\Software\\test\\October.db");
var destination:File = File.documentsDirectory;
destination = destination.resolvePath("copy.db");
original.addEventListener(Event.COMPLETE, fileMoveCompleteHandler);
original.addEventListener(IOErrorEvent.IO_ERROR, fileMoveIOErrorEventHandler);
original.moveToAsync(destination);
function fileMoveCompleteHandler(event:Event):void {
trace(event.target); // [object File]
}
function fileMoveIOErrorEventHandler(event:IOErrorEvent):void {
trace("I/O Error.");
}
This fails, as does using D:\Software\test\October.db
I guess what I want to know it - how do you do the resolvePath thing if you already know the full path?
I guess what I want to know it - how do you do the resolvePath thing if you already know the full path?
You don't AFAIK. If your path is actually d:\software\test\october.db you can set a File ref like:
var original:File = new File();
original.nativePath = "d:\software\test\october.db";
