File browsing - using keyboard

Which key can you use to navigate backwards while file browsing?

Command plus either the up arrow or [ depending if you want to go up one folder or back to the previous one viewed in that Finder window.

Open Document File Browser using button

I want to add a button to my PDF that when clicked opens the document file browser to a specified folder. How can this be done? All the information I've found requires you to enter the name of the document you're inserting rather than opening the browser window.
Also, is it possible to setup a button to open a specified folder and insert the latest pdf file in that folder?
I am somewhat familiar with JavaScript.

Hi,
According to your post, my understanding is that you wanted to click the Document ID link to open the document directly without prompting an open\save dialog.
By design, some specific documents such as .doc or .xlsx files can’t be opened directly when you click the Document ID link.
As a workaround, I recommend that you can install the Office Web App to implement it in your environment.
For more information, you can refer to:

Open file browser?

Hello all!
I'm currently trying to create an interactive cd-rom using
flash. The dilemma I've come across is opening windows' file
browser to the cd's root. I can get it to open file browser using
an external .exe file. I'm guessing it's going to have to be
written in the .exe however, I don't have the expertise to know
how. I'm guessing one of you flashers on here have accomplished
this already!
thanks!
-E

I have the same problem! I come up with many solutions and
researched everything but no luck!
Did anybody answer to ErOx's question?
ErOx - have you solved it?

Remote Browsing using RMI

Hi,
Read a lot of forums about how to create a Remote file browser using RMI and JFileChooser.
Not done any RMI coding I thought I'd give it a try. I have finally after 2 days managed to do it.
This is an overview.
Create a RemoteFile class that extends Remote.. eg.
import java.rmi.*;
import java.io.*;
import java.net.*;
public interface RemoteFile extends Remote {
 public boolean canRead() throws RemoteException;
 public boolean canWrite() throws RemoteException;
 public int compareTo(File pathname) throws RemoteException;etc.etc
Then create an implementation class...
import java.rmi.server.*;
import java.io.*;
import java.net.*;
public class RemoteFileImpl extends UnicastRemoteObject implements RemoteFile {
 private File f;
 public RemoteFileImpl(File sf) throws java.rmi.RemoteException {
 f=sf;
 public boolean canRead() throws java.rmi.RemoteException {
 return f.canRead();
 }etc etc for all other File functions.
Then we create a RemoteFileSystemView interface, again extending remote...
public interface RemoteFileSystemView extends Remote {
 public RemoteFile createFileObject(File dir, String filename) throws RemoteException;
 public RemoteFile createFileObject(String path) throws RemoteException;blah blah
Then An implementation class...
import javax.swing.filechooser.*;
import java.io.*;
public class RemoteFileSystemViewImpl extends java.rmi.server.UnicastRemoteObject implements RemoteFileSystemView {
 int length;
 private FileSystemView fs;
 public RemoteFileSystemViewImpl() throws java.rmi.RemoteException {
 fs=FileSystemView.getFileSystemView();
 public RemoteFile createFileObject(String path) throws java.rmi.RemoteException {
 return new RemoteFileImpl(fs.createFileObject(path));
 public RemoteFile createFileObject(java.io.File dir, String filename) throws java.rmi.RemoteException {
 return new RemoteFileImpl(fs.createFileObject(dir,filename));
 //public RemoteFileImpl createFileSystemRoot(java.io.File f) throws java.rmi.RemoteException {
 // return new RemoteFileImpl(fs.createFileSystemRoot(f));
 public RemoteFile createNewFolder(java.io.File containingDir) throws java.rmi.RemoteException {
 RemoteFile tempf;
 try{
 tempf= new RemoteFileImpl(fs.createNewFolder(containingDir));
 } catch (IOException e){System.out.println(e); tempf=null;}
 return tempf;
 public RemoteFile getDefaultDirectory() throws java.rmi.RemoteException {
 return new RemoteFileImpl(fs.getDefaultDirectory());
 public String[] getFiles(java.io.File dir, boolean useFileHiding) throws java.rmi.RemoteException {
 String[] tempf= new String[fs.getFiles(dir,useFileHiding).length];
 int i;
 File[] f = fs.getFiles(dir,useFileHiding);
 for(i=0;i<tempf.length;i++) tempf=f[i].toString();
return tempf;
public RemoteFile getHomeDirectory() throws java.rmi.RemoteException {
return new RemoteFileImpl(fs.getHomeDirectory());
public RemoteFile getParentDirectory(java.io.File dir) throws java.rmi.RemoteException {
return new RemoteFileImpl(fs.getParentDirectory(dir));
public String[] getRoots() throws java.rmi.RemoteException {
String[] tempf= new String[fs.getRoots().length];
System.out.println("fs is-"+fs.getRoots().length);
int i;
File[] f = fs.getRoots();
for(i=0;i<tempf.length;i++) {tempf[i]=f[i].toString();}
System.out.println("Roots="+tempf[0]);
return tempf;
public String getSystemDisplayName(java.io.File f) throws java.rmi.RemoteException {
return fs.getSystemDisplayName(f);
public javax.swing.Icon getSystemIcon(java.io.File f) throws java.rmi.RemoteException {
return fs.getSystemIcon(f);
public String getSystemTypeDescription(java.io.File f) throws java.rmi.RemoteException {
return fs.getSystemTypeDescription(f);
public boolean isComputerNode(java.io.File dir) throws java.rmi.RemoteException {
return fs.isComputerNode(dir);
public boolean isDrive(java.io.File dir) throws java.rmi.RemoteException {
return fs.isDrive(dir);
public boolean isFileSystem(java.io.File f) throws java.rmi.RemoteException {
return fs.isFileSystem(f);
public boolean isFileSystemRoot(java.io.File dir) throws java.rmi.RemoteException {
return fs.isFileSystemRoot(dir);
public boolean isFloppyDrive(java.io.File dir) throws java.rmi.RemoteException {
return fs.isFloppyDrive(dir);
public boolean isHiddenFile(java.io.File f) throws java.rmi.RemoteException {
return fs.isHiddenFile(f);
public boolean isParent(java.io.File folder, java.io.File file) throws java.rmi.RemoteException {
return fs.isParent(folder,file);
public boolean isRoot(java.io.File f) throws java.rmi.RemoteException {
return fs.isRoot(f);
public Boolean isTraversable(java.io.File f) throws java.rmi.RemoteException {
return fs.isTraversable(f);
public RemoteFile getChild(File parent, String fileName) throws java.rmi.RemoteException {
return new RemoteFileImpl(fs.getChild(parent,fileName));
Notice that whenever I should be passing a File, I pass a RemoteFile instead! Also.. when I am passing a File Array, I instead pass a String array. Reason is.. I havent managed to get File arrays through RMI.. Any Help anyone?!?!?!?!
I got round it by simply passing a String array and relying on the client to reconstruct a File array locally using the String array. Messy... perhaps.. any suggestions welcome!
Next.. use rmic to create Stubs and Skels for the 2 implementations and write an RMI server.. eg.
import java.rmi.Naming;
public class RemoteServerRMI {
 /** Creates a new instance of RemoteServerRMI */
 public RemoteServerRMI() {
 try {
 RemoteFileSystemView c = new RemoteFileSystemViewImpl();
 Naming.rebind("rmi://localhost:1099/FileService", c);
 } catch (Exception e) {
 System.out.println("Trouble: " + e);
 public static void main(String[] args) {
 new RemoteServerRMI();
}Yes.. simple and shamelessly lifted from the tutorials.
and Finally the client....
import javax.swing.filechooser.*;
import java.rmi.*;
import java.net.MalformedURLException;
import java.io.*;
import javax.swing.*;
public class RemoteFileSystemViewClient extends FileSystemView {
 static RemoteFileSystemView c;
 public RemoteFileSystemViewClient() {
 try {
 c = (RemoteFileSystemView) Naming.lookup("rmi://localhost:1099/FileService");

Notice.. the getFiles and getRoots, procedures, get String arrays from the RMI and reconstruct local File arrays.
I managed to browse up and down directories with this, and even.. to my surprise, create folders!
If you got any improvements please let me know at [email protected]

File Browser

hi,
pleas if y can give me resources or ideas how to develop file browser using j2me.
this file browser can browse the memory card or the phone memory .
and how to serach on file and to delete files ..
specily for nokia 6600 phone whech is have its own hard Disk "like computers" which you can browse it.
thnx.

Hi,
If you have the latest WTK (2.2) with JSR 75
75 support then u can find a file browser example.Hi,
can i make a file browser if the device didn't support JSR 75?
how if i want to make a file browser with MIDP 1.0?
thank you...
PS: I'm sorry if my english is bad ;p

How to open a pdf file in a web browser using jsp

Hi,
I have a problem opening pdf file in browser using jsp.the following is my code.Can anyone help me.Thanks
response.setContentType("application/pdf");
String filename="C:\\FictPos\\mypdf.pdf";
File file = new File(filename);
FileInputStream in = new FileInputStream(file);
OutputStream out1=response.getOutputStream();
byte[] buf = new byte[4096];
int count = 0;
while ((count = in.read(buf)) >= 0)
out1.write(buf, 0, count);
in.close();
out1.close();
}

Don't know the problem specifically, but here are some suggestions to investigate:
Does it show anything in the page when you view source on it?
I would recommend using a servlet rather than a JSP page for this, if only for the fact the JSPs can insert carriage returns into places where you might not want them to. This might screw up the PDF file format?
Try setting the a link to the jsp, right-click and "save target as..." just to see if it gets any response at all - ie bypass the browser display.
Good luck,
evnafets

Using File Browse to update stored file

Hi all,
I have a form with a File Browse item on it which is (surprisingly!) used to upload a file and associate with a record. The filename is stored in a varchar column in the table. This works fine when I create (INSERT) the initial record and I can retrieve the stored file just fine. However the problem I have is when I want to update the uploaded file. It seems the normal mechanisms for update / save requests don't apply to uploaded files. My other attributes get updated fine but the new uploaded filename is not reflected in the table.
I've put together a simple example of this on a when apex.oracle.com :
http://apex.oracle.com/pls/otn/f?p=40740
Which has two fields, a file name and an 'attribute'. Try as I might I can't update the file name although the attribute changes just fine.
Any suggestions will be much appreciated. I realise I may be missing something fundamental here and am more than happy to be enlightened.
FYI, the purpose for such functionality is to allow users of our system to store a photograph of themselves along with their details. This functionality is required to allow the photograph to be updated if required.
Thanks,
Steve

If i am not mistaking, using a file browser item type will not set the uploaded file (blob) in this item, to be processed in the standard processing on you're page.
In a recent project i wrote a stored procedure for handling with uploaded files. This procedure, which based on the filename ( Fnnnn/<filename> ) , select the uploaded content through apex_application_files, the location apex saves the files. and procedure outputted the file as a blob, which then can be used to insert/update in youre table
Hope this example code will help you:
procedure upload_bestand( p_file_name in varchar2
, p_file out nocopy blob
, p_filetype out nocopy varchar2 )
is
-- Cursor voor bepalen bestand uit apex_application+files
cursor c_file ( b_file_name in varchar2)
is
select aaf.filename
, aaf.mime_type
, aaf.blob_content
from apex_application_files aaf
where aaf.name = b_file_name
r_file c_file%rowtype;
begin
open c_file ( b_file_name => p_file_name );
fetch c_file into r_file;
if c_file%notfound
then
-- Upload van bestand niet geslaagd
close c_file;
raise e_file_err;
end if;
close c_file;
-- Geupload bestand uit temp_upload tabel verwijdern
delete from apex_application_files
where name = p_file_name
commit;
p_file := r_file.blob_content;
p_filetype := r_file.mime_type;
end upload_bestand;

How to know if a file browser item is not null using javascript fucntion

Hi
 
I tried to use javascript for validation. I have a file browser item named P55_FILE_NAME and I would like to know if this item is null or not before submit.
 
I wrote this function : 
function validate_import(f_n){ 
 if (trim(document.getElementByName(f_n).src) == "") 
 { 
 alert ("File name is empty."); 
 document.getElementByName(f_n).focus(); 
 } 
 else{ 
 doSubmit('SUBMIT'); 
 } 
} 
When I press submit button I got an error, sounds like the src method does not exist in my input item. 
Then, I looked my source page an I found this : 
input type="file" name="p_t01" size="30"
 
there is know src method and the name is not P55_FILE_NAME and I don't want to use p_t01 that will change. 
 
I need your help.

Hello,
The p_txx notation is the internal name the ApEx engine attaches to each page item. It starts with p_t01 (for the first item on page) and can end with p_t99 (hence, the max 99 items per page limit). You can see these names in your HTML source code.
The bug in the File Browse item (fixed in version 2.2) is that the ID of the item is the internal name instead of the item name. Hence, in order to use DOM, you need to use this internal notation.
If the File Browse item id is p_t01, you can null its content by using something like that (V2.0 notation) :
html_GetElement('p_t01').value = '';I'm using the same, and similar code, for manipulating this type of item with no problems.
Please document the use of this workaround, as when you'll upgrade your ApEx system, you will have to change this code back to the standard – item id equal item name.
(Please follow Scott's advise, and keep your logic connected issues on the same thread. It will get you more quick and accurate help).

Arie.

Unable to open PDF file in browser using Reader 9 with IE8

I just updated to IE8 and when trying to open a PDF file on the browser, I received a message stating to use Adobe Reader 8 or 9. I downloaded AR9 and still receive the same message and cannot open PDF files in browser window. It defaults to my Adobe Acrobat 6.0 which will not open the file. I have Windows XP. I do not have a problem opening a PDF file in Yahoo mail with AR9. I have tried many different ideas on the web to no avail. Appreciate any help to be able to default to open PDF files in the browser using AR9 which is apparently required by IE8.

Fixed problem by taking to a computer store to find that my hard drive storage was maxed out. I had the hard drive repaced with a larger amount of storage. Problem resulted from inadequate amount of storage space which prevented me from downloading and installing Adobe Reader 9.
Thanks to al that responded.

Using File Browse Item To Get File Only

Is it possible to use the file browse item to just get the file without inserting it anywhere?
I'm looking to allow a user to "upload" a file from their client machine... but what will actually happen in the process is it will take the file and send it in an e-mail to whomever needs to get it.
Or is the only way to allow it to insert the file, do what I need to do with it, and then immediately delete it?
Thanks,
Chad

Uploading the file to server from the browser using JSP

Check out http://www.jspsmart.com , They have a nice free upload api that can be used w/ JSPs or Servlets. I hear O'Reilly has a nice one too. May as well use someone elses if they've done it already.

How to view crawled documents of file system in the browser using sharepoint search

Hi,
I think this should be pretty obvious. However, somehow I am not able to do it. Here is what i am working on:
I created a folder on my D:\ drive on the SharePoint server. Added a few word documents there.Created a new content source in my Search Service Application and configured it to crawl above folder from file system. Ran a full crawl. All the documents are
crawled successfully. I can see the documents on the search page. Now, the problem is:
How can I open this document directly in the browser? Becuase the path i get is of the folder on the server. If this isn't possible then I think,there is no use of this feature. I just see the title and a short description of the document.
But, I think it should be possible. I just don't know how to do it.
Any ideas will be highly appreciated.

Hi Mohan,
According to your description, my understanding is that you want to open the documents in file shares in the browser by clicking the link in search results.
As the files are not stored in SharePoint, so we need to configure Office Web Apps for the documents to open the files in the browser.
Here is a similar thread for you to take a look:

How to set "Files of type" when using a "File Browse" item.

Apex 4.0.2
Internet Explorer 7 +
I have a "File Browse" item on a page and need to limit the types of files display to just "text (.txt)" files. How can this be done? Currently, the "Files of type" list shows "All File (*.*)", "Pictures (*.gif,*.png)", and HTML (*.htm,*.html)". In the best case, I would like to not have the "Files of type" list and have the user just limited to text files. However, adding Text files (*.txt)" to the "Files of type" list is ok.
thanks,
William

Thought i'd do a bit of research after seeing Scotts wonderful ideas.
So it turns out, IE made the file item read only from version 8, for security reasons. Read more: http://blogs.msdn.com/b/ie/archive/2008/07/02/ie8-security-part-v-comprehensive-protection.aspx
File Upload Control
Historically, the HTML File Upload Control (<input type=file>) has been the source of a significant number of information disclosure vulnerabilities. To resolve these issues, two changes were made to the behavior of the control.
To block attacks that rely on “stealing” keystrokes to surreptitiously trick the user into typing a local file path into the control, the File Path edit box is now read-only. The user must explicitly select a file for upload using the File Browse dialog.
Additionally, the “Include local directory path when uploading files” URLAction has been set to "Disable" for the Internet Zone. This change prevents leakage of potentially sensitive local file-system information to the Internet. For instance, rather than submitting the full path C:\users\ericlaw\documents\secret\image.png, Internet Explorer 8 will now submit only the filename image.png.To resetting the actual items, suggestions I found were to replace the actual item. So instead of using $s, I just replace the element, with the existing element, causing it to re-initialise.
var htmldb_delete_message='"DELETE_CONFIRM_MSG"';
function fileCheck(el){
 if(el.value){
 var validFile = false;
 var validExtensions = ["csv"];
 var filename = el.value;
 var fileExtIndex = filename.lastIndexOf(".");
 var fileExt = filename.substring(fileExtIndex+1, filename.length);
 for(i = 0; i < validExtensions.length; i++){
 if(validExtensions[i] == fileExt){
 validFile = true;
 break;
 if ( !validFile || fileExtIndex == -1) {
 alert("Invalid Extension. Permitted files must end with: " + validExtensions.toString());
 var htmlContents = el.outerHTML || new XMLSerializer().serializeToString(el);
 $('#P16_BINARY').replaceWith(htmlContents);
}(obviously, replacing what you need to, to suit your page - i prefer scotts idea of passing in supported file types in the function, so would just pass in an array instead; but this is just for demonstration)
with an onchange="checkFile(this)" on the element attributes.
On a slightly un-related note, I found out IE doesn't support the wonderful indexOf function on arrays, that checks for the existence of the value in an array. Sucks.

Ah well, jQuery is there, maybe i should use that for searching arrays in the future.

Creating file browser GUI using java swing tree

Hi all,
I have some questions which i wish to clarify asap. I am working on a file browser project using java swing. I need to create 2 separate buttons. 1 of them will add a 'folder' while the other button will add a 'file' to the tree when the buttons are clicked once. The sample source code known as 'DynamicTreeDemo' which is found in the java website only has 1 add button which is not what i want. Please help if you know how the program should be written. Thx a lot.

How to move files by using a keyboard command?

On Windows or Ubuntu, If I choose a file, press control & x and press control & v in a different folder, the file can be moved easily without dragging the file in to the destination folder. I tried to do the same thing on Mac OS X, but Mac OS only allows me to use apple & x if I tried to cut texts. Is there any way to use keyboard commands or other ways to move files not by dragging?

no. you can not cut files in OS X. But you can copy and paste with command+c and command+v. also, you can install a 3rd party contextual menu to move files which will be available from the right-click menu.
