Reading local file in VC

Hi All,
Is it possible to open a local file with some path like C:\temp\...... in VC?
Regards,
Murtuza

Hi Govinda,
Do you know the format how to write the path of the file in the field 'file name' of the HTML view?
Is there a possibility that the user is prompted to enter the file path on runtime?
Best regards

Reading local files

I need to read local files in C with Alchemy (at least on
developer's machine). This should allow more rapid application
development with Lua Alchemy -- as developer would be able to
exclude swf build step.
I have added directory with my .swf to the FlashTrust config.
I'm able to load the file with URLLoader. However fopen() on it
returns NULL. Please see the attached code.
Executables, compiled with Alchemy (and run with swfbridge),
are able to work with local files. What should I do to allow my
application to work with local files in the same manner?
Alexander.

I have tried fopen(), and it does not work (see code in
original post). I would like to get working fopen() (and family)
somehow, so I would be able to get vanilla Lua sources to work with
files.
My other option, of course, is to replace file-related
functions in core Lua libraries. This is not that hard, and even
doable without modifying of Lua sources, but I'd like to avoid this
solution.
UPD: I have looked at the libpng sample. If I get it
correctly, funopen() there operates on ByteArray, not on actual
file. (I have no experience with BSD API, so it was not immediately
clear for me.)
I need to operate on actual file on local file system.
Thank you,
Alexander.

AccessControlException in signed applet for simply reading local file

I have a simple applet that reads specified local image files and uploads them to our server. On both Mac OS X and WinXP (firefox and IE7), I get the following error. I signed the applet using an InstantSSL code signing certificate (not so easy getting this to work, but I'm pretty confident I did it correctly).
java.security.AccessControlException: access denied (java.io.FilePermission /Users/scott/Documents/photos/Ken_and_Scott.jpg read)
     at java.security.AccessControlContext.checkPermission(AccessControlContext.java:264)
     at java.security.AccessController.checkPermission(AccessController.java:427)
     at java.lang.SecurityManager.checkPermission(SecurityManager.java:532)
     at java.lang.SecurityManager.checkRead(SecurityManager.java:871)
     at java.io.File.length(File.java:813)
     at org.apache.http.entity.mime.content.FileBody.getContentLength(FileBody.java:89)So just on getting the file length, it's throwing this exception. Interestingly, this file passed both file.exists() and file.canRead() checks within the applet (in windows the path is a bit different of course but also passes both those checks). Also, that file has no read restrictions and I can load it in a browser no problem.
I assume I'm missing a step in the applet code signing process, maybe a step that says I'm allowed to read local files?

I figured out my issue, the apache HttpClient library needed to be signed too apparently.

Read local file in background

hi everyone,
i need to read local file in background,
wich function do i need to use?
thanks,
dana.

if you are reading in background file needs to be on application server.
you can use following function modules.
CALL FUNCTION 'TMP_GUI_DIRECTORY_LIST_FILES'
OPEN DATASET FILENAME FOR OUTPUT IN TEXT MODE
MESSAGE MSG_TXT.
IF SY-SUBRC NE 0.
WRITE: 'Err', MSG_TXT.
EXIT.
ENDIF.
LOOP AT INT_TAB
*your code
ENDLOOP.
Closing the File
CLOSE DATASET FILENAME.

Applet can't read local file on web server, security issue!

There is any way to read/write files of web server through the applet except the Signed Applet.
If any idea the reply me soon.
Thanks in advance

Applets are downloaded from web servers and execute on the client machine.
Therefore they have no access to the web server file system, signed or not.
They could have access to the client file system (the machine where they run),
but for security reasons only signed applets have this privilege.
So to answer your question, you sign if you want to access client files.
To access web server files, you don't need to sign the applet, but you need
to provide some method of accessing files remotely, for instance:
- Files published for the web can be read using HTTP
- Files can be read or writen with the help of an FTP server on the same machine as the web server
- A servlet running on the HTTP server can collaborate with your applet to exchange files

Is reading local file possible?

Hi,
My intention is to use Flash 8 Pro as a tool allowing to
upload large files
into the server (something like FTP client). Unfortunately a
lot of servers
have tight restrictions for transmition time (sometimes
limited to 30s).
Work around to this could be a Flash. I couldn't find any
information in
Flash documentation about reading binary files selected by
user by
HTML-like file field. I would like to read selected file,
split it into
severeal smaller parts and then upload every part separately
into the
server. Is it possible?
Regards,
Marek

Yes, I know that. That is the reason why I have written
'somethig like FTP'.
Ok, once again... I can create PHP script to receive POST
uploads. This is
no problem to me. The problem is that iddle time for scripts
on this
particular server is set to 30 seconds only. It means that I
can't upload
files for which transfer time will be longer then 30s. To
work around this
issue it is necessary SPLIT uploaded file into the chunks
then transfer it
to the server and join using e.g. PHP script. I need a tool
embeded on web
page which allows me to select large file (large sometimes
means 1MB) and
send into the server jumping over server time limitations.
Flash contains
build-in FileReference class but there is no described in the
documentation
how to send selected file as e.g. 4 separate parts of it.
> There is an upload samples which comes with
> flash and can be located under the SAMPLE directory on
your C drive in the

It is also described in Flash help under FileReference class
description.

Problem with File panel and Local files

I am having a couple of problem using Dreamweaver (which may be related) and can’t find any appropriate help on the web site.
I have created a small website and have it up and running.    I’m now trying to do some minor modifications.     But Dreamweaver seems to have lost the address of my local files on my home computer (although files are still there in the same place.)     In the on-line training material it shows how to define where the root directory is when you start developing a site, but I can’t find where these setting are so I can check and if nessessary amend them.   If I go to Define Site from the Site drop down options, this does not allow me to check or define the root directory.
Secondly, in the File panel (lower right on the screen) the address bar at the top only shows the remote files and the icons to the right (“put”, “get”, etc) have disappeared and I can’t seem to get them back.   Also that lower panel seems to be floating rather than being fixed like it was.     I have tried clicking on Classic View in the Workspace layout options but this doesn’t move things back to how they were when I first started using Dreamweaver (just a few weeks ago).
Can you offer any advice on what the problem is and how to manage it? Many thanks.   I'm using Dreamweaver CS4 and an iMac.

Immediately below the Tabs saying "Files" and Assets" is a small box
with arrow on the right to show the drop down list.        In the box
on the right there's an icon of two networked computers. Then it
says, "ftp://Hill farm Web Site" which is the name of my website.
If I click on the arrows to pull up the drop-down box, I get four
options divided by a line.   Above the line the options are Computer,
HD and ftp://Hill farm Web Site. Below the line it says manage sites.
Below this is list of files that make up my website in a directory
structure.   The header for the first column reads, "Local Files",
which appears to be untrue, because the top line in the directory
structure below reads, "ftp://Hill farm Web Site".
Does this help?

Code to read local notepad.txt from applet

Hi.
Further to my (unanswered) queries about reading a notepad.txt file from the local directory i.e. the same directory from which the html and applet were launched, the following code is supposed to be able to read the local file. It failed to do so both in Netscape 7.1 and in IE5
I've also received conflicting advices : some says we can read local files without using a signed applet or chaning the ACL, whereas others I'll need to use signed applets and / or acl to allow the applet to read a local file.
My research has shown that java applets are supposed to be able to read local files. Has something changed:
public class FileAccess extends Applet
   implements ActionListener {
   Button loadButton, saveButton;
   TextField filename;
   TextArea content;
   String browserName;
   boolean securitySupported = false;
   public void init() {
     setLayout(new FlowLayout());
     Label label =
       new Label("Simple file editor");
     add(label);
     loadButton = new Button("Load");
     saveButton = new Button("Save");
     add(loadButton);
     add(saveButton);
     loadButton.addActionListener(this);
     saveButton.addActionListener(this);
     filename = new TextField(20);
     add(filename);
     content = new TextArea(5,20);
     add(content);
     browserName = System.getProperty("java.vendor");
     if (browserName.indexOf("Netscape") > -1)
        securitySupported = true;
     setSize(200, 200);
   public void actionPerformed(ActionEvent evt) {
     if (securitySupported) {
        if (evt.getSource() == saveButton) {
           PrivilegeManager.enablePrivilege("UniversalFileAccess");
           try {
              FileWriter aWriter = new FileWriter(filename.getText(), false);
              aWriter.write(content.getText());
              aWriter.flush();
              aWriter.close();
           catch(Exception e) {
             e.printStackTrace();
        else if (evt.getSource() == loadButton) {
           PrivilegeManager.enablePrivilege("UniversalFileAccess");
           try {
              BufferedReader aReader =
                 new BufferedReader
                    (new FileReader(filename.getText()));
              content.setText(aReader.readLine());
              aReader.close();
           catch(Exception e) {
             e.printStackTrace();
      else {
        getAppletContext().showStatus("security not installed");
}

Hi acinhk,
I read your note with great interest. I am trying to solve almost exactly the same problem as you are -
Reading a .txt file in IE5 from the same directory where the html and the applet were lauched.
Your code looks fine to me.
My code is very similar, and again generates a security exception - as I am having the same problem you had getting around Java security.
If you have been able to solve the problem, can you please let me know what you did.
Any modifications to your sample code that actually made it work would be greatly appreciated.
Also, is signing the applet to read a local file under IE5 really necessary ?
Can the file be read from the local IE file system without signing the applet ?
Please let me know your thoughts.
Thanks !

Upload local file

Good Morning,
This is the scenario:
I put my applet in webserver. User go to this server (eg. http://www.test.com) and execute my applet
through web-browser. Now, this user wants to upload files. Is this possible?
I want the applet to be able to read the local file and save it to the database (JDBC). But all I need
is the technique to read local file. Sample source code will be appreciated.
Please help.
Thank You.

Good day,
I need an example how to upload file using applet. If there's one out there, you can search for it here or try Google, but I don't recommend this approach.
Applet is a must.I seriously doubt that, as I can't recall hearing of this type of a requirement since the invention of Applets.

How to read the contents of a file present in local file system

Hi ABAP Experts,
I want to read the file contents of a file in the local system. I want to read it stream based i.e if the file is if 100kb in size, i want to read the first 100bytes at one time, next 50 kb after, and remaining some other time. Is this possible. I know that with GUI_UPLOAD i can get the total contents into a xstring.
But how to resolve the following i am not sure. Can you please help.

Reading files from local hard disk - Access Local Files Only

Hi All,
I have a local flash file published as 'Access Local Files Only', to allow me to read from local filesystem.
What methods or classes can I use to read text and other files from the user's harddisk.
This is the first time I am trying to do something like this, all help is grealy appreciated.
Thanks
Andy

Hi, thanks for the responses
I did some searching and found that the urlloader class is the right one for the job.
'Access Local Files Only' option is provided for this very purpose I believe.
If anyone has done something like this and have some sample code it would be awesome

Help with utl_file (read/write file from local directory)

Need help reading/writing file on local machine from plsql using 10.2 DB.
I am trying to read/write a file from a local directory(laptop) without success.
I have been able to read/write to the database server directory but can't write to directory on local machine.
The utl_file_dir parm has been set to * and the db restarted but I can't get it to work... Here's the plsql statement.
out_file := UTL_FILE.FOPEN ( 'C:\PLSQL', 'TEST.TXT', 'W' ,32767);
Whenever I run it continues to write to c:\PLSQL dir on the database server. Have looked at the "Directory" object and created MY_DIR = C:\PLSQL but it writes to the db server.
Running 10.2 on a remote windows server, running PLSQL using sql*navigator.
Thanks in advance for your help..

I don't see how you expect the server to be able to see your laptop across the network, hack into it and start writing files. Even if it could, what if there is more than one laptop with a C: drive? How would it know which one to write to?
Is there a shared drive on the server you can access via the laptop?
