I have a String variable in my flex (flash builder 4) application containing CSV data. I need to allow the user to download this data to a local file. For example, giving them a "csv" button to click and it might present them with a save file dialog (and I would be sending the contents of my string variable).
Is this possible / how ?
I am using the ResuableFX component for the datagrid to csv. This the code I ended up with that works to save the string to a text file for the user (in a web browser):
var dg2CSV:DataGrid2CSV = new DataGrid2CSV();
dg2CSV.includeHeader=true;
dg2CSV.target=adgEncounters;
var csvText:String=dg2CSV.getCSV();
var MyFile:FileReference = new FileReference();
var csvFileNameDT:String = QuickDateFormatter.format(new Date().toString(),"YYYYMMDDJJNNSS");
MyFile.save(csvText,"Encounters"+csvFileNameDT+".csv");
If you're in an AIR App you can use File.browseForSave().
If you're in a web app, you can use FileReference.save() . The FileReference docs have a lot more info on this.
In many cases, I would recommend using navigateToURL() to open the file outside of Flash and let the browser deal with it.
I'm not sure if there is a way to do this without user interaction.

I am using the accept property in the fileUpload control to only allow certain file Types and prevent uploading .exe or other potentially harmful files.
application/msword,application/vnd.openxmlformats-officedocument.wordprocessingml.document,application/vnd.ms-excel,application/vnd.openxmlformats-officedocument.spreadsheetml.sheet,application/ms-powerpoint,application/vnd.openxmlformats-officedocument.presentationml.presentation,application/pdf,text/plain,image/gif,image/jpeg,image/pjpeg,image/png"
This works, however I am using a Tool called Burp Suite that allows me to intercept an acceptable file eg .txt that could contain harmful code and change the filename extension to .exe which is then upload to the X-Page database.
When I goto save the document and after Interception and changing to a .exe, I have added the following code to identify an exe file:
Can we manipulate what has been uploaded and change the file extension to a harmless .txt ?
var fileData:com.ibm.xsp.http.UploadedFile =facesContext.getExternalContext().getRequest().getParameterMap().get(getClientId('fileUpload1'));
if (fileData != null) {
var tempFile:java.io.File = fileData.getServerFile();
// Get the path
var filePath:String = tempFile.getParentFile().getAbsolutePath();
// Get file Name
var fileName:String = tempFile.getParentFile().getName();
// Get the Name of the file as it appeared on the client machine - the name on the server will NOT be the same
var clientFileName:String = fileData.getClientFileName();
}
var fileRight = clientFileName.slice(-4);
if (fileRight == ".exe")
{
//facesContext.getExternalContext().getRequest().getParameterMap().get(getClientId('fileUpload1').replace(".exe",".txt"))
//facesContext.getExternalContext().getRequest().getParameterMap().get(getClientId('fileUpload1').remove(".exe",0))
}
Yes, you can. You have on the properties of control two options 'Use original file name of uploaded file' and 'Replace file name of uploaded file...' where you can put name with extension 'name.txt' . I didn't try to change only extension... That is probably better in code to replace.
I'm currently converting a Chrome extension into a Firefox add-on and would appreciate to replicate the chrome.storage.sync feature.
However, I cannot manage to find whether the data stored by a Firefox add-on using simple-storage will be automatically synced whenever a user of the add-on is signed into Firefox Sync.
Given that all the pieces of data stored via the latter method can be found in the user profile, I presume it will... as long as the add-on is available at https://addons.mozilla.org ?
Any information on the topic would be greatly appreciated.
simple-storage is not synced. But you can sync it with little effort.
The trick it to store the storage object, it is serializable by definition, as a string preference and tell to the sync service to synchronize it.
Lets name that preference syncstorage and mark it as synchronizable.
var self = require("sdk/self");
var prefs = require("sdk/preferences/service");
prefs.set("services.sync.prefs.sync.extensions." + self.id + ".syncstorage", true);
When storing something to simple-storage reflect the change to syncstorage.
var sp = require("sdk/simple-prefs");
var ss = require("sdk/simple-storage");
sp.prefs["syncstorage"] = JSON.stringify(ss.storage);
For the opposite effect watch syncstorage for changes
sp.on("syncstorage", function(prefname){
ss.storage = JSON.parse(sp.prefs["syncstorage"]);
})
Last but not least, It would nice and perhaps mandatory to sync only with the explicit consent of the user.
Hei there, I'm using PrimeFaces 5/JSF 2 and tomcat!
Can someone show me or give me an idea on how to store pdfs for a limited time on an application server(I'm using tomcat) and then download it (if that's what the user requests). This functionality relates to invoices so I can't use the dataExporter.
To be more specific, I pretty much implemented this but I don't feel so sure about it. One big question is... where do I store my generated files? I've browsed around and people said that it's not ok to save the files in the webApp or in the tomcat directory. What other solutiuon do I have?
Make use of File#createTempFile() facility. The servletcontainer-managed temporary folder is available as application scoped attribute with ServletContext.TEMPDIR as key.
String tempDir = (String) externalContext.getApplicationMap().get(ServletContext.TEMPDIR);
File tempPdfFile = File.createTempFile("generated-", ".pdf", tempDir);
// Write to it.
Then just pass the autogenerated file name around to the one responsible for serving it. E.g.
String tempPdfFileName = tempPdfFile.getName();
// ...
Finally, once the one responsible for serving it is called with the file name as parameter, for example a simple servlet, then just stream it as follows:
String tempDir = (String) getServletContext().getAttribute(ServletContext.TEMPDIR);
File tempPdfFile = new File(tempDir, tempPdfFileName);
response.setHeader("Content-Type", "application/pdf");
response.setHeader("Content-Length", String.valueOf(tempPdfFile.length()));
response.setHeader("Content-Disposition", "inline; filename=\"generated.pdf\"");
Files.copy(tempPdfFile.toPath(), response.getOutputStream());

Your question is vague, but if my understanding is good:
First if you want to store the PDF for a limited time you can create a job that clean you PDFs every day or week or whatever you need.
For the download side, you can use <p:fileDownload> (http://www.primefaces.org/showcase/ui/file/download.xhtml) to download any file from the application server.
I am using Web activity to launch default Firefox camera from my web app in Firefox OS. Able to launch default Firefox camera and took picture. Got this.result as return value inside pick success.
Now I need to get file path, where image get saved and also image file name.
Tried to parse the this.result.blob, but couldn't find the path or file related parameter .
Below is the code I'm using
var activity = new MozActivity({
// Ask for the "pick" activity
name: "pick",
// Provide the data required by the filters of the activity
data: {
type: "image/jpeg"
}
});
activity.onsuccess = function() {
var picture = this.result;
console.log("A picture has been retrieved");
};
The image file name is not returned, as you can see from the code. If you would need the file name (I can't really think of a very good use case to be honest) you can iterate over the pictures storage in the DeviceStorageAPI and get the last saved file. It's probably the one from the camera (compare blobs to be totally sure).
In your success handler, you will get the file name if you use:
this.result.blob.name
And, you can get the path to the file as:
window.URL.createObjectURL(this.result.blob);

In XPages, in the file upload control, after a user selects a file but before it's saved how can you get the filename? I'm not interested in the path as I believe that's not getable due to security issues but I would like to get the filename and extension if at all possible.
Thanks!
Actually you can get the file and fully manipulate it, read it, do whatever you want with it, its stored in the xsp folder on the server, to which you have read/write access... here is a code snippet that interacts with the file, I usually call from beforeRenderResponse...
var fileData:com.ibm.xsp.http.UploadedFile = facesContext.getExternalContext().getRequest().getParameterMap().get(getClientId('<INSERT ID OF UPLOAD CONTROL HERE (ie. fileUpload1)>'));
if (fileData != null) {
var tempFile:java.io.File = fileData.getServerFile();
// Get the path
var filePath:String = tempFile.getParentFile().getAbsolutePath();
// Get file Name
var fileName:String = tempFile.getParentFile().getName();
// Get the Name of the file as it appeared on the client machine - the name on the server will NOT be the same
var clientFileName:String = fileData.getClientFileName();
}
It sounds like you are referring to needing to get the data via CSJS, which you can do with the following code:
var filename = dojo.byId('#{id:fileUpload1}').value.split('\\').pop();
