Open a file in Flex?

By googling, I can find lots of examples of opening a local
file in Flash, but none of them work with Flex (for instance,
import flash.filesystem.*; )
I can get the target object by using the FileReference, but
OnSelect, how can I open that file for reading?
Please note: I do not need to upload it to the server, I only
need that data on the client side, and it would be a real pain to
have to send it to the server just so that the server could echo it
back.
Any help would be appreciated.

As I understand it, for security reasons, local files cannot
be accessed with Flash. You need to use AIR to access the local
file system. Assuming you are creating an AIR app, importing the
flash.filesystem.* and mx.events.FileEvent; you would do the
following...
[Bindable]
private var myFile:File = new File;
myFile.browseForOpen();

Rangrajan,
If you have the complete URL to the file; for example http://forums.adobe.com/filename.pdf

How to open user file in Flex Application

Hi forum,
I develop flex2 application where user can browse and open
XML file: the file should be loaded to text area.
Could you, please, advice me how to browse and open user
file?
I found FileReference class but it looks that it can only
upload file to a server. I need to open the file in flex
application.
Thanks for your help.

The issue isn't Flex, but the Flash Player. It is too much of
a security risk to allow SWFs running in the Flash Player to open
local files. Imagine going to a web site that has a SWF banner ad -
but that banner ad opens local files and sends them to a remote
system - all of your personal and financial information transfered
without your consent.
Flex apps running in the AIR player are different - the end
user must launch them explicitly, just like any other local
program.

Error Opening File in Flex Builder 3

I'm getting the attached error when I try to open a file in
Flex Builder.
The base error states "Error opening the editor". I can open
other files without a problem. It is just this one file I am having
a problem with.
I can open the file with no problem in Notepad. I renamed the
file and tried to create a new MXML file with its original name and
copy the code from Notepad, but when I try that I get this error:
"Paste" did not complete normally. Please see the log for
more information.
String index out of range: -1
Please help me.
Thank you.

The only thing I can think of that could have caused this was
this line of code:
<mx:Button label=">" />
Would that do it? If so, shouldn't Flex Builder simply show
me a warning instead making the file completely
inaccessible?

Adobe reader issue there was an error opening this file. the file cannot be found. How to fix this?

We are opening pdf file in flex air application. but for some user we are facing this issue.

Problem is not being able to open pdf attachments. Get this error message: "There was an error opening this document. The file is damaged and could not be repaired."
I searched on the web and in the context of a discussion I located, an Adobe professional posted this solution: HKCU\Software\Adobe\(product name)\(version)\AVGeneral\bValidateBytesBeforeHeader=dword:00000000.
I am accustomed to attempting to fix things myself, but I am not a computer science person so it's always a stretch for me. If I get a little guidance I can usually make necessary corrections. I hope that I can with this issue..
Still hoping that someone will know how to fix the error problem which according to what I read is a software issue having to do with the program not understanding something in the pdf header...

How to open pdf files in browser using flex

hi,
my project is having a Document explorer wchich contains pdf
files,iwant to open it in the browser.can any one tell me how to
open pdf documents using flex programming(i tried with different
thing like swf's but my client wants only pdf formatt).

Another option is by calling a JSP page. This example will
open a pdf file into a new browser without displaying the download
"save" prompt.
Function to call the JSP:
private function downloadFlyer(event:Event):void {
var jspLink:URLRequest = new
URLRequest("jsp/downloadpdf.jsp?fileName=Fundraiser_flyer_2008.pdf");
navigateToURL( jspLink, "_blank" );
JSP code:
<%@ page errorPage="error.jsp" %>
<%@ page import="java.io.*" %>
<%
//Get the parameters
String downloadFileName=request.getParameter("fileName");
String fileName = application.getRealPath("/downloads/" +
downloadFileName);
File file = new File(fileName);
if (!file.exists()) {
throw new IOException("File does not exist.");
// Get the size of the file
long length = file.length();
// You cannot create an array using a long type.
// It needs to be an int type.
// Before converting to an int type, check
// to ensure that file is not larger than Integer.MAX_VALUE.
if (length > Integer.MAX_VALUE) {
throw new IOException("File too big.");
response.reset();
response.resetBuffer();
response.setContentType( "application/pdf" );
response.setHeader ("Content-Disposition", "filename=" +
downloadFileName);
//Prevent the Java error: "getOutputStream() has already
been called for this response"
out.clear();
out = pageContext.pushBody();
InputStream in = new FileInputStream(file);
OutputStream output = response.getOutputStream();
try {
int curByte=-1;
while( (curByte=in.read()) !=-1){
output.write(curByte);
} catch (IOException ioe) {
ioe.printStackTrace(System.out);
} finally{
output.flush();
in.close();
response.flushBuffer();

Opening a file in its native application from Flex.

Is it possible to open a file on whatever native application the user runs it as? Or even, at that, to simply open the directory it's in, in an explorer window?
We have a search application and the frontend is in Flex, and I'm trying to find a way to do this, such that when a use double clicks on a result (in a datagrid - but that's trivial), it opens the file or at least the location of the file on the OS.
Any system call where I can say system("explorer.exe " + filepath); or something?
Any help would be appreciated.

Dear BillBlalock ,
thank you for answer!! You are very kind and helpful!! I would like to inform everybody that I have finally find another way of soilving my problem and I announce it to the forum in case somebody else encounters the same problem. Well, I soved the nproblem by using the following code:
    excelButton.addActionListener(new ActionListener()
       public void actionPerformed(ActionEvent e)
         String filePath = "\""+saveFileName.toString()+"\"";
         System.out.println(""+filePath);
         try
           String cmd="explorer "+filePath;
           Process p = Runtime.getRuntime().exec(cmd);
         }catch(IOException ec){}
     });I hope it can be useful to somebody!! By this code, I can make a button (in my case the excelButton) to open any file in its default application. Keep up the great work you are doing guys!!

False File.exists; flex cannot open SQLite.db file

I have a program that uses an SQLite database. Instead of creating and importing the database, the sqlite databse already exists, with the data.
I am trying to open it and read the information (select* from table - for example); But nothing i do seems to work.
The error I am getting is: 'Error #3125: Unable to open the database file.', details:'Connection closed.', operation:'open', detailID:'1001'. I have checked the path repeatedly, The file exists. I run flash builder as administrator (win7).
code:
I have moved the database file all around. In the final version of the program, the database will be stored in a seperate drive on a network (Z:/database.db, for example) So i need to use the absolute path; although i have tried others (application storage directory, etc)
var dbFile:File = new File("C:\Users\Public\Documents\graduates.db");
trace('exists:' + dbFile.exists);
//above being the important bit.
dbStatement = new SQLStatement();
dbStatement.itemClass = Grad;
aluDB = new SQLConnection();
dbStatement.sqlConnection = aluDB;
aluDB.addEventListener(SQLEvent.OPEN, onDatabaseOpen);
aluDB.addEventListener(SQLErrorEvent.ERROR, errorHandler);
aluDB.open(dbFile);//error occurs here, of course.
can anybody help me figure out why this error is occuring? Or even just a different method of opening the file?

Hello,
I have an Oracle Express Edition 10g running on
Redhat Enterprise Linux 4 server.
I have an Oracle database file which is 2.1 GB in
size. I am not able to open this file using the
application or the Oracle sql developer. The error
message that I get is:
ORA-01110: data file 5:
'/usr/lib/oracle/xe/oradata/XE/service_3_0.dbf'
ORA-27041: unable to open file
Linux Error: 13: Permission denied
I think this has to do with the fact that since it is
not a 64-bit Linux but a 32-bit Linux, it does not
support files larger than 2GB. What do you think I
should do to tackle this problem?
Best Regard
ThayalanThat's interesting! I had no problems with opening files 32767MB in size on the very same 32 bit RH EL 4.0. How did you conclude that your file is too large, based on the error message which reads "Linux Error: 13: Permission denied"? Have you tried reading the manual page for the "open" system call and see when does it return EACCESS (error 13), found in /usr/include/asm-i386/errno.h. My man page for open says the following:
ERRORS
EACCES The requested access to the file is not allowed, or search per-
mission is denied for one of the directories in the path prefix
of pathname, or the file did not exist yet and write access to
the parent directory is not allowed. (See also path_resolution(7).)
What lead you to the conclusion that your file is too big? Do you have an access to a system administrator who knows how to use "strace"? If your system admin doesn't know how to use "strace", he too deserves waterboarding.

Opening file in flex

Is it possible to open a file using relative/absolute path..I do see ways to browse/load the files but not to open a file with the given path..
Thanks in advance

The Adobe Flash player operates in a sandbox. This means it can't access files on the users's machine without explicit permission. You can do this by, as you said, browsing for a file using a FileRef (file reference).
You can, however, access data placed on a server machine (relative to where your swf is stored), or across domains (swf on one server, data on the other). To access data across domains, you need a crossdomain.xml file placed on the server containing data that tells Flash what it can and cannot access.

How to display pdf file in flex application

hi,
I am Ibran, I am using Flex4.5, in that i want to display a pdf file like images.
How can i do it please anyone tell me.
I have used navigateToURL(url),but this was going into navigation and i can't see my textfield and buttons.
So without this navigateToURL(url) how can i display a pdf file in flex without navigation so that i can see my textInputs and buttons.

Flash does not have the ability to load/display/manipulate PDF files, so you can't open it directly in the flex application. With clever HTML and javascript, you can make it appear that it is in the same window, but it will actually be in a separate window/div in the browser. And yes, this has always seemed absurd to me that Adobe doesn't support PDF's......
