Open a file dialog box using java

Duncan & Frank or anyone
Can you please tell, or give me a link, which explains how to open a file dialog box using java, and not webutil.
I'm trying to read a file on the desktop and update a database table.
Thanks

See Open File Dialog on the WEB... If you can get me the full version numbers I can tell you your supported position.

Opening a File Dialog Box

Hi,
could somebody help me with how to open a file dialog box.
I have 1 class which has a window with the relevant widgets on it, I want to be able to click a button on the form and pop up a file chooser form then select a file or type in a new filename and then use the selected filename path in the original form to write data out to the chosen file.
i understand that i need to use JFileChooser and it will need to be in a new class (like a dialog box would be).
So basically what i have is 2 classes (the main app and a class called FileOpen.class) so how would i display the fileopen class with the JFileChooser component in it and return what ever is chosen into a string.
e.g.
String fileName = <what would go here?>
kind regards

thats the example filechooser i have working
yet when i try and implement it in my program i just get countless exception errors, im not sure if its because my program extends Jframe and not JPanel
here is my code:-
package as4;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.border.*;
import java.util.*;
import javax.swing.filechooser.*;
import java.io.*;

'Open a File' dialog box doesn't show 'Favorites'

InDesign CS6, Windows 7:
File/Open gives me this:
Notice there are no 'Favorites' on the left. I have to 'browse' for my file each time. I have a ton of files on the network, and it takes several clicks to get to them. Annoying when I'm opening several files a day. The 'Recent Places' isn't too helpful here either.
Now look at what happens in InDesign CC, Windows 7 with a File/Open:
Look at all the 'Favorites' and easy browsing on the left side. Why are the 'Open a File' dialog boxes so different in CS6 and CC? I want the CS6 'Open' dialog to be just like the CC one. (I prefer to use CS6, CC is buggy on my system.)

Not helpful.
What it is... is cumbersome and un-necessary. Every other program in Windows (even Word Pad) opens with the 'standard' dialog with Favorites on the left. Why did Adobe program it differently? There has to be a fix in Preferences or something...

Open a File Dialog Box to browse through image files

Hi all
I need to develop a code to open a File Dialog Box to browse through Image Files in Oracle 10g.
Once the Image File is selected i need to save the file in a Table Column in the Backend Table.
Please help me.
Thanks
Nakul Venkatraman

Hi
Thanks for your prompt response on this.
I came across a Sample Form File which would allow the User to browse through files from local PC.
Following is the code :
declare
dirname varchar2(255);
v_filename varchar2(255);
begin
message('1');
tool_env.getvar('E:\', dirname);
message('2');
dirname := dirname || '\project';
message('3');
v_filename := get_file_name(dirname,NULL,
'All Files (*.*)|*.*|' ||
'JPEG Files (*.jpg)|*.jpg|' ||
'Bitmap Files (*.bmp)|*.bmp|' ||
'TIFF Files (*.tif)|*.tif|' ||
'CompuServe Files (*.gif)|*.gif|' ||
'PC Paintbrush Files (*.pcx)|*.pcx|' );
message('4');
if v_filename is not null then
read_image_file(v_filename,'ANY','pp_foto.foto');
end if;
end;
The code is written inside WHEN-BUTTON-PRESSED Trigger.
When i run the form it is not opening the dialog box.
Please help.

Hi.. I found the JDIC binary files. There are different binaries for all the plateform. Is there any solution which is independent of plateform.Yes, and we already told you: Use JDK6, which has those libraries built into the standard class library.
How can I use these binaries in my existing project. does it work, If I place them at same place where other .class files are kept.Read the documentation of the JDIC project. I'm sure they answer this question in their FAQ.

InDesign CS6: The "find" function doesn't work in "Open a file" dialog box...

I am using CS6 on OSX 10.7.5. When I try to search in the OPEN DIALOG box, it NEVER lists anything, not even a close match. If I however search the SEARCH feature on OSX it always finds what I'm looking for. Is there a setting that I have to change to get this to work or is it a glitch? thanks so much!

Exact same issue here.
CS6, OSX 10.8.3.
Example below ("Call Log," third item in first screen shot showing all files on Desktop, does not show up in the "Open a File" search for "Call Log" as shown in second screen shot):

InDesign CS6: "find" function doesn't work in "Open a file" dialog box

Thanks so much!
I'm using a Mac OS X version 10.7.5. I've been using inDesign for YEARS and depend on that find.
Any other info you need????

Opening a file dialog box with a button while the data graph is running continuos aquisition

I am running a continuous aquisition that is hardware timed. I display the data on a graph. While running the VI that is displaying the graph I want to open a file to write the data for a period of time then be able to select a new file after the file is written by hitting the open file button again. I also want to just have the file open and after it is opened hit another button that begins the writing to the file.

To accomplish the first task use a control button, a case structure and a sub vi located inside the case structure. The control button determines the status of the case structure in response to user click. The sub vi writes your data into the file you specified in the file dialog. The entire process repeat itself each time the button is clicked. The set-up of the sub vi depends on organization and type of file you want. I think the second task is just a modification of the first.

Open/Save File Dialog Box comes up, then does not respond for a long time or not at all

I will click a link for a download and the box will pop up saying
"You have chosen to open "blahblah.blah.blah
Which is a: blah file
From: www.randomsite.com
What should Firefox do with this file?
Open with
Save File"
At this point other than being able to see the box, it is as though it doesn't exist. I can't click okay or cancel or choose what to do. Sometimes after a few minutes it will suddenly work, other times it will just remain until Firefox closes.

You can also try to clean install the new version after deleting the [http://kb.mozillazine.org/Profile_folder Profile Folder] as well as the [http://kb.mozillazine.org/Installation_directory Installation Folder.] Please see [https://support.mozilla.org/en-US/kb/Backing%20up%20your%20information?s=backup&r=1&e=sph&as=s this] for backing up important info. The '''places.sqlite''' file stores the bookmarks and history, the '''key3.db''' + '''siqnons.sqlite''' files are needed to successfully restore the saved passwords etc.

When I hit the escape key to close out the open file dialog box, firefox hangs or crashes.

When I open the "open file" dialog box using the ctrl+O and then hit the escape key to exit the box, I get an error message which I'm not able to paste here.
it says something about a runtime problem and if I try the same thing again to reproduce the problem, it will sometimes just hang and windows vista will tell me the program is not responding.
I've checked to see if there are any crash IDs but none were found for this time frame.
I have even disabled all add ons.
I'm currently using vista 64 bit edition and Firefox 6, beta edition.

Hi,
Please also try right-clicking on the link corresponding to the language version and '''Save Target As''' to save the Firefox installer. If the problem persists, posting [http://answers.microsoft.com/ here] would also be helpful.

Open File Dialog Box (JS)

I know that in order to open a file dialog box and get a file I have to use this code:
myFile = File(File.openDialog("Import XML","XML Files: *.xml"))
This is what I use to open XML files. Now I want to be able to open a folder based on the label of the textFrame. I can get the label and build the file path. How can I open a dialog box that already points to a specific folder? Also, how can I check with the script if there are files within the folder?
Thanks,
Justin M.

>How can I open a dialog box that already points to a specific folder?
var myFolder=Folder("/C/XYZ");
var myMask="INDD:*.indd";
var myFile=myFolder.openDlg("Select Files To Open", myMask, true);
>Also, how can I check with the script if there are files within the folder?
var myFolder = Folder.selectDialog("Please select path to files");
if (myFolder!=null) {
var fileList = myFolder.getFiles();
alert("The selected folder contains " + fileList.length + " files.");

What is the open File Dialog box

I am using a "File Browse..." item. With firefox a user can click on the provided Browse button or the corresponding text area to choose a file. However with IE7 the file dialog box on appears if the user clicks on the browse button.
Can someone tell me what javascript can be used to open a file dialog box? (what is called when the browse button is clicked)
Thanks.

Thanks Carl,
I thought APEX was doing some crazy javascropt stuff because I forgot about a style I had set.
Anyway, I was getting an error if an IE7 user types in a crazy string into the file dialog box and hit submit (since it is not a file). So instead of preventing it I just used a try/catch block in my custom doSubmit. If anyone else runs into this here is a little javascript to help:
(I am used a uploading image, Carl has an example of that somewhere)
<pre>
function doSubmit(r) {
if (ser_changed.length > 0) {
 if (r == "UPLOAD" || r == "SAVE_CHANGES" {
 flowSelectAll();
 $x_Value('pRequest',r)
if (r == "UPLOAD") {
try { /// this is where my fix is.
 document.wwv_flow.submit();
catch(err) {
html_HideElement('AjaxLoading');
alert('Invalid file');
} else {
document.wwv_flow.submit();
 }//save changes and stuff as request.
else {
 var ans = confirm("You are about to exit the page without saving your changes!" + '\n' + "Click cancel to return to the page.");
 if (ans) {
 flowSelectAll();
 $x_Value('pRequest',r);
 document.wwv_flow.submit();
 }//when yes!
$x('CANCEL_BUTT').disabled=false;
 }//not save changes and stuff
 }//when there were changes made.
 else {
 flowSelectAll();
 $x_Value('pRequest',r);
 document.wwv_flow.submit();
 }//where there were not changes made
 }//doSubmit
</pre>
<pre>
function html_Submit_Progress(pThis,topass){
 if(pThis.nodeName=='INPUT'){pThis.value='...Loading...'}
else{pThis.innerHTML='...Loading...'};
 html_ShowElement('AjaxLoading');
window.setTimeout('$x("wait").src = $x("wait").src', 100);
doSubmit(topass);
</pre>

File Dialog Box often takes a long time to execute

Hi all
The Labview File Dialog Box Express VI sometimes takes 5 to 10 seconds to execute. On other occasions, it executes in a blink of an eye. Why is that so?
I have tried to use the older Open/Create/Replace File VI as suggested in one of the forum's posts...but it behaves exactly the same way. Another problem is the trimming of the filename, which has also been reported and has NOT YET been solved.
(By the way...Recently, I updated to LV 2012 SP2 by suggestion of the NI Update Manager, only to find out that I was not entitled to this SP (which apparently only includes bug fixes) and I will have to roll back to LV 2012. Still, in the evaluation version I can see that the bug is not fixed. Labview must have a lot of serious bugs for NI to ask for a paid bug fix, in which some bugs remain after having been reported a long time ago..well...)
What worries me now is that intermittent lag in the execution of the File Dialog (such a basic basic function of a program...). Anyone have any idea about this? The support menu said "Ask an engineer"...any of the NI engineers has any suggestion?
Regards
Helder

First of all: Thank you very much for the objective answer. I suppose that yor actually ARE a NI engineer, as I had hoped for.
lease find my comments above (helder---------------------)

The file dialog is provided by the OS, so if it is slow it is not LabVIEW's fault.
What kind of computer do you have? Is this a laptop that spins down the HD to save power? In this case it needs to wait for the HD to spin up. (You can change the windows power profile or you can spend more money and get an SSD).
Are you very low on memory?
Does your LabVIEW program waste 100% CPU in parallel doing nothing due to bad coding?
Are you pointing to a location that has millions of files?
Are you pointing to a network location?
helder:---------------------------------------
I understand that the File Dialog is provided by the OS. But I have other applications on my PC and this doesn't happen - just in Labview. Sorry! And sometimes it
doesn't happen. Every 10 times I open the File dialog Box, 5 times it takes long and 5 times it is immediate.
(I am not low on memory, my coding is not bad>-look at the VI I sent, it just contains the fragment which uses the File Dialog Box and it behaves the same way! I am pointing to the same location that the other applications point to, I am not pointing to a network location, the PC is not spinning the disk down, etc etc.)
But yes, I will try it on another PC
(There was another post on the forum on this issue, but can't seem to find it now, just find my own post )
I attach a video demo of what happens.

What problem is that? Can you elaborate? There is a known bug in the windows dialog box that sometimes the pre-filled file names are shifted and not fully visible. This is a windows bug documented by Microsoft and LabVIEW has no control over it. It is not NIs job to fix OS problems.
helder:-------------------------------------------
Of course you can't fix the OS.
If it is a windows bug, we will have to live with it.
A previous post on your forum did not provide me with that information (http://forums.ni.com/t5/LabVIEW/File-dialog-trimming-the-default-name/td-p/2189874). The fact that it is a windows bug was not mentioned there.

(By the way...Recently, I updated to LV 2012 SP2 by suggestion of the NI Update Manager, only to find out that I was not entitled to this SP (which apparently only includes bug fixes) and I will have to roll back to LV 2012. Still, in the evaluation version I can see that the bug is not fixed.
Patches are included, service packs are not included. I think this is well documented. Most users are on SSP, this way you are always entitled to the newest version.
As with anything else, software has bugs. It is impossible to test a huge, complex system like LabVIEW under all scenarios. The possible number of combinations of hardware and other installed software on any particular computer probably exceeds the number of atoms in the universe. It is actually amazing how few bugs there are and how well it works. What "bug" are you talking about? Bugs are prioritized according to rules. Critical bugs are typically fixed very quickly. A cosmetic issue that only affects you and nobody else will take longer or might not even get fixed. Are you talking about a confirmed bug that could be reproduced by NI? Do you have a CAR#?

I was referring to the file-name-shifting-cosmetic-bug that the October-2012 post had indicated. But if it is a Windows-bug, NI does not have any responsibility, of
course.
Regarding the bugs, of course they are unavoidable.

Labview must have a lot of serious bugs for NI to ask for a paid bug fix, in which some bugs remain after having been reported a long time ago..well...)
That sentence makes no sense! Why would the number of serious bugs depend on the cost of upgrading?? You are just rambling here....
In an ideal world, NI would have an unlimited number of programmers that can work 24/7 to immediately fix any discovered bug. This would only be possible if all users are willing to pay an unlimited amount of money for the software. As I mentioned, bug fixes are free in the form of patches, and they come out regularly. Service packs include new features and are not free.

"....include new features"..????
---->>From http://www.ni.com/labview/release-details/
"LabVIEW 2012 Service Pack 1 is an exclusive update to LabVIEW 2012 for NI Standard Service Program (SSP) customers. There are no new product features introduced in service pack releases; instead, these releases provide bug fixes and improved stability for LabVIEW 2012. For a list of these bug fixes, click here."
No new features, just bug fixes!"
Moreover: If it isn't free, it shouldn' have let me update if I am not a SSP costumer.
Now I have a 45 days evaluation version. After that, I have to uninstall and reinstall everything.That takes some time and effort.
If there is a more direct way of rolling back t the previous version, please let me know.
Thank you

File Dialog Box Position

Hi there,
I've been unable to find anyone else mention this problem, but then again, I'm not exactly what to search for.
Since installing Lion, I've had a problem where when I try to open the file dialog box to save or open a file, it's position is always further down. This is annoying, especially for programs that open files from my Download folder, which is continuinally growing as I add more stuff. The sort on this is by date, and so usually I want to open the most recently downloaded file, which I have to scroll further and further up each time.
Is there any way I can get it to jump to the top?
See the attached image to see what I mean exactly.
Thanks!

the length of the session is not the problem. it is set to 50bpm at 29.97 drop frame which gives me 2138 bars at 3 hours 51 minutes record time. I only used 1896 bars at 2.5 hours to record the program and there were only 5 tracks recorded. the problem starts when I try to bounce the session to an interleaved stereo file either online or offline. a dialog window says it will exceed 2gigs and prevents me from performing the bounce. only when I select split stereo instead of interleaved within the bounce window does it let me bounce. I think it is because the 2 resulting mono files(left and right)are each less than 2gigs. Is there a limit to the file size you can create when bouncing?
a 2gig file sounds small to me when there are video files much larger within video editing software.

File Dialog's using Remote Panels (via web server)

I am aware that the web server remote panel access will not allow us to open a file dialog box on a remote computer. I have read people comment that you should create your own file dialog box, using LabVIEW to use instead of the file dialog box.
Has anyone actually done this? I would like know if anybody has source code for this, rather than re-inventing the wheel. Also, will the sub-vi actually just appear on the webserver? i.e. will it actually work?
Thanks for any help

Hi Emilie,
I have a program that I run on an industrial PC, with no keyboard, video or mouse. We currently control the application using the web server. We have a button to load and a button to save settings. If the files are missing for the load & save, it pops up a file open dialog to choose the file to import. However, while we are viewing the page this way, these dialog boxes do not work.
I would like to know if anyone has made up a file dialog box that I could use, that would display correctly in the web server's remote control.
Regards,
Slade
