Open FileDialog
Hi all,
I'ld like to open the windows file explorer dialog to select a specific file like in the attachements system.
However, I don't want to copy the selected file in the Attachement folder.
I just want to get the path of the file.
Is there a solution to do that?
Thanks.
Ok thanks,
This code from William Burgos Posted Apr 22, 2008 9:40 PM works fine!

FileDialog in Applet throwing security exception.
I am trying to create a simple applet that a user can select a file from and then upload that file to a server somewhere. I am able to accomplish this using the JApplet class and the JFileChooser class. Everything works fine with the signed applet. However I am going to need to make it compliant with the Microsoft VM since it is for a corporate settings and those people won't have admin rights on their machines to toggle between the VM. So JApplet has been changed to Applet, JFileChooser has been changed to FileDailog and now I am getting this error:
com.ms.security.SecurityExceptionEx[com/java/applet/il/AimsImporter/AimsImportApplet.actionPerformed]: FileDialog creation denied.

This line of code is where it blows up:
FileDialog fileDialog = new FileDialog(new Frame(), "Please choose the file to open:", FileDialog.LOAD);The jar is signed, however something of interest to note: there isn't a pop-up asking me if I would like to trust this applet when I use the Microsoft VM?
jar.exe -cvf k:\applet\lib\Importer.jar com.java.applet.il.AimsImporter/*.class
jarsigner k:\applet\lib\Importer.jar mykey
jarsigner -verify Importer.jar
Is there something that is different when doing this with the Microsoft VM?????

Can someone please help me? I'm not sure why the class "OpenDialogFile" below is not working. I really appreciate your help.
I got this following error:
ChatClient.java:66: cannot resolve symbol
symbol : constructor FileDialog (ChatClient.OpenDialogFile,java.lang.String,int

Here is my code:

input = new TextField(50);
sendButton = new Button("Send");
quitButton = new Button("Quit");

}All constructors for FileDialog require an instance of Frame as a parent. ChatClient.OpenFileDialog apparently doesn't meet this requirement hence compiler is complaining.

Hi,
I need to save path which was last using by SaveFileDialog to saving file. But I can't find this path.
I checked all items in Environment, Application, Configuration and I not finded that.
Is there any solution to find this path?This has been previously answered
http://social.msdn.microsoft.com/Forums/vstudio/en-US/c43ddefb-1274-4ceb-9cda-c78d860b687c/how-to-get-the-last-directory-after-open-filedialog
also try this link
http://stackoverflow.com/questions/9821344/how-to-remember-the-last-path-when-insert-files-into-listbox
and you can try this
public static string GetLastOpenSaveFile(string extention)
RegistryKey regKey = Registry.CurrentUser;
string lastUsedFolder = string.Empty;
regKey = regKey.OpenSubKey("Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\ComDlg32\\OpenSaveMRU");

Hi.
I am trying to place image on canvas.
However the image doesn't show!!!!!!!!!!!!! :(
no error and compiles well....
private void AddTile(String image, int startx, int starty, int endx, int endy)
try{
tiles = ImageIO.read(new File(image));
catch(Exception e)
System.out.println("Image not Found");
Graphics2D a =(Graphics2D)tiles.getGraphics();
a.drawImage(tiles, 20,20,20,20,TileCanvas);
if the above function is called the image should be placed on canvas right?
TileCanvas is a canvas, and tiles is BufferedImage.
just in case I'll put my source code followed by this

}You have at least two problems.
1) You are mixing AWT and Swing. Instead of using a Canvas you should use either a JComponent or a JPanel.
2) In Swing, drawing such are you are doing should be done within the paintComponent(Graphics g) method using the Graphics provided as an argument to the method.
P.S. I can't test you code because for some reason you feal the need to use a NetBeans specific layout manager. -
Executing UNIX command in Java
I am having problems executing a command in Java. Here's the code I have for executing:
Process p = Runtime.getRuntime().exec(cmd);
BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));

num_1 = Double.parseDouble(display);
percent = (num_1 * 100) / (50000000);
flip = 1;
catch(IOException e)
e.printStackTrace();
System.exit(1);

The same applet
A DESCRIPTION OF THE PROBLEM :
Unable to run signed applet with Netscape 4.79 and IE5.5
native JVM.
REGRESSION. Last worked in version 1.3.1
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1.compile program and copy class files to a temp directory
2.sign the applet for Netscape as follows:
signtool -k aok -d \progra~1\netscape\users\viravan -Z
FIO.jar temp
3.sign the applet for Internet Explorer as follows:
cabarc -p n FileIO.cab FileIO*.class
setreg 1 true
makecert -sk aok -n "CN=aok" aok.cer
cert2spc aok.cer aok.spc
signcode -j javasign.dll -jp LOWX -spc aok.spc -k aok
FileIO.cab
Run the applet with the following HTML file:
<html><head><Title>Self-Signed Applet</Title>
<script>
document.layers ? parm=1 : parm=0;
</script>
<body>
This file I/O applet lets you read and write to the user's
local disk.<br>
<br>
<script>
document.writeln('<APPLET CODE = "FileIO" CODEBASE = "."
ARCHIVE = "FIO.jar" WIDTH = 10 HEIGHT = 10 NAME = "JSF">');
document.writeln('<param name="Netscape"
value="'+parm+'">');
document.writeln('<param name="cabbase"
value="FileIO.cab">');
document.writeln('</APPLET>');
</script>
</body>
</html>
EXPECTED VERSUS ACTUAL BEHAVIOR :
A frame with a textarea and some buttons should popup in the
center of the screen.

Hi,
I've been given an application which I have to modify to edit a 'raw' image, so far I have been able to implement the loading of the image, but I am stuck with editing it.
The there are 3 classes to the application, rawimage, skelappipcanvas and skelappipframe.
So far as to my understanding, the rawimage class loads the raw image into a pixel array and then converts it into an image which is then displayed on the canvas. The frame contains the menu.
What I have to do is edit the picture, by manipulating the array, adding 5 to all values in the array for example. I understand that the best way to do that is to create a function and call that function when I select the menu option.
My problem is that im not sure how to implement the editing of the array..any pointers would be greatly appreciated. I have posted the code below..sorry for the amount of text.

}Recommendations include:
* Use code tags when posting code. No one likes to look at unformatted code. To do this, either highlight your code block and press the "code" button at the top above the message block or place the tag [code] at the top of your block of code and the tag [/code] at the bottom, like so:
[code]
// your code block goes here
[/code]* Post a much smaller amount of code. I seriously doubt that anyone will look at your code given its length.
* But still if possible, have your posted code be compilable and able to demonstrate your problem. This is called an SSCCE and you can read up on it here:

JXMLTool (EnterpriseOne 8.98)
Introduction:
The JXMLTool is a GUI tool developed by Global Support Services to submit XML requests to ERP enterprise servers. The tool can be used to verify the integrity of the ERP services (kernel configuration, BSFN processing, among others) when testing inbound integrations from XPI and/or other third party systems to ERP. This document contains instructions on how to install and configure the tool.
Installation and Configuration:
1) Verify that a supported Java Development Kit (JDK) is installed in the workstation to be used in the test (for example, verify that JDK 1.4.2 is installed).
Note: It is recommended that the workstation also have an EnterpriseOne 8.12 full client package installed.
2) Create a new directory in the workstation (for example, C:\JXMLTool).
3) Copy the following files from the Deployment server to the directory created in step 2:
e812\system\classes\Base_JAR.jar
e812\system\classes\JdeNet_JAR.jar
e812\system\classes\System_JAR.jar
e812\system\classes\log4j.jar
e812\system\classes\xerces.jar
e812\system\classes\xalan.jar
e812\system\classes\ManagementAgent_JAR.jar
e812\system\classes\jmxri.jar
e812\system\classes\commons-httpclient-3.0.jar
e812\system\classes\commons-logging.jar
e812\system\classes\ xmlparserv2.jar
e812\system\classes\ jmxremote_optional.jar
e812\system\Classes\samples\jdeinterop.ini.templ
e812\system\Classes\samples\jdelog.properties
Note: If you have multiple-foundation implemented in the system, make sure the files you are copying match the service pack level installed in the enterprise server.
4) Rename jdeinterop.ini.templ to jdeinterop.ini. Modify the jdeinterop.ini file copied in step 3 to reflect the correct enterprise server name:
a) Ensure that parameters glossaryTextServer in [SERVER] section, serviceNameConnect in [JDENET] section, and enterpriseServer, port in [INTEROP] section specify the correct enterprise server name and JDENET port number).
b) Configure the value of Repository under [INTEROP] section such that it points to the directory created in step 2 (for example, “Repository= C:\JXMLTool”).
c) Ensure that parameter SecurityServer in [SECURITY] section specify the correct security server.
d) Configure OCMEnabled to “false” in [OCM] section.
e) Add the parameter netTrace to [JDENET] section and configure its value as “1” (for example, “netTrace=1”)
5) Rename jdelog.properties.templ to jdelog.properties. Modify the jdelog.properties file to reflect the characteristics of the machine:
a) Ensure that jdelog.handler.JDELOG.File points to directory created in step 2 (for example, jdelog.handler.JDELOG.File=C:/JXMLTool/jderoot.log).
b) Ensure that jdelog.handler.JASLOG.File points to directory created in step 2 (for example, jdelog.handler.JASLOG.File=C:/JXMLTool/jas.log).
c) Remove comment marks from parameters jdelog.Debug, jdelog.handler.jasdebug, jdelog.handler.jasdebug.File, and jdelog.handler.jasdebug.Level.
c) Ensure that jdelog.handler.jasdebug.File points to directory created in step 2 (for example, jdelog.handler.jasdebug.File=C:/JXMLTool/jasdebug.log).
6) Create a new text file using the text editor of your choice (for example, Notepad).
7)Paste the following text to the new document:
@echo off
REM Edit this file to the locations for Java and EnterpriseOne
REM JDK root directory
set JAVA_HOME=C:\j2sdk1.4.2_12
set PATH=C:\j2sdk1.4.2_12\bin
REM EnterpriseOne Windows client install path
set OneWorld_HOME=C:\e812
REM This directory
set EXAMPLES=C:\Interop\JXMLTool
REM Set the CLASSPATH environment variable.
REM The following are libraries that are needed for Connector samples:
set CLASSPATH=Base_JAR.jar
set CLASSPATH=%CLASSPATH%;C:\Interop\JXMLTool\
set CLASSPATH=%CLASSPATH%;C:\Interop\JXMLTool\JXMLTool.class
set CLASSPATH=%CLASSPATH%;JdeNet_JAR.jar
set CLASSPATH=%CLASSPATH%;System_JAR.jar
set CLASSPATH=%CLASSPATH%;log4j.jar
set CLASSPATH=%CLASSPATH%;xerces.jar
set CLASSPATH=%CLASSPATH%;xalan.jar
set CLASSPATH=%CLASSPATH%;ManagementAgent_JAR.jar
set CLASSPATH=%CLASSPATH%;jmxri.jar
set CLASSPATH=%CLASSPATH%;commons-httpclient-3.0.jar
set CLASSPATH=%CLASSPATH%;commons-logging.jar
set CLASSPATH=%CLASSPATH%;xmlparserv2.jar
set CLASSPATH=%CLASSPATH%;jmxremote_optional.jar
set CLASSPATH=%CLASSPATH%;%OneWorld_HOME%\system\classes\
a) Ensure that "set JAVA_HOME" command sets the variable with correct path to JDK directory (for example, "set JAVA_HOME=c:\jdk142").
b) Configure value of OneWorld_HOME such that it points to the directory where OneWorld® is installed (for example, “set OneWorld_HOME=C:\e812”).
c) Ensure that "set EXAMPLES" command sets the variable with the correct path to directory created in step 2 (for example, "set EXAMPLES=C:\JXMLTool").
d) Configure value of JDEINTEROPINI such that it points to the jdeinterop.ini file you copied in step 3 (for example,
“set JDEINTEROPINI=%EXAMPLES%\jdeinterop.ini”).
e) Append the path of the bin directory of the JDK to the PATH variable. For example, add the following line:
“set PATH=%JAVA_HOME%\bin”
8) Save the file as setenv.bat in the directory created in step 2 (for example, C:\JXMLTool\setEnv.bat).
9) Create a new text file using the text editor of your choice (for example, Notepad).
10) Paste the following text to the new document:

Help plz-internalFrames--buttons-video..any jgurus around??
Hi to all
My name is Dimitrios and i am developing a program which is consisted by a client program and a server program. The purpose of the application is to stream video (TV channels) to the client.The server program is used to authenticate the client (at the moment) where the client after the authentication is providing a GUI in order to choose the Chanel and watch the video.In more detail:
Client site:
2 classes ( frames)
The 1st frame (login.java) prompts for username and password. The server (prog) authenticates the pass and if correct the client "moves" to the next frame (by set visible false to the 1st frame).
The 2nd frame (client.java) is the actual GUI of the program. It is consisted by two buttons (assume we have two T.V channel options) and an internal frame which is where the video is displayed.
In order to develop this program i have split up the tasks and try to solve each task at a time. What i mean is:
1)Create an authentication procedure (DONE)
2)Create the GUI of the client (DONE)
3)Create the operation where button is pressed and video is played IN THE INTERNAL FRAME (in progress)
4)Stream video (in progress)
Since i don't know yet how am i going to produce the streaming what iv done is to embed a simple quicktime player in the client and open a movie file to produce video. I need to produce the video in the internal frame first.
My question is:
1) How am i going to produce the video in the internal frame after the button is pressed. Note that the button is not in the internal frame (obvious i think).
2)i decided to use quicktime player API cause during my research i fpund out that is the best option.I did trie JMF but i wasnt that satisfied. Do you propose any other solution. I did try to find out if i could embed Windows Media player in my frame but i didn't find any info regarding WMP and java frames.
I do have some knowledge about java but i wouldnt consider my self an advance programmer. THIS IS NOT A JOB CASE but a presentation from my UNI.
Thanks in advance for reading all this.

Hi! where's the problem. this is ver 2.00 of eph; and ver 1.00 worked correctly.
I just can't find the problem. kysymykset = null, whyHave you checked so that you havent serialized it as
null?Thanks, I think you are right, that I should check null-selialization. I must have algoritm-problem with save-method(), it propably saves object as null and there's nothing...
Otherwise I would recomend to put in traces and see
were you get it set to null.
By the way, do you get exceptions on this one? yes; lueTiedot()-> nullPointerException -

JMF FrameGrabbingControl does not exist
I am trying to capture screenshots of the video playing.
to do this i am using FrameGrabbingControl but it is always null.
So i checked it and by using GetControls method i took a look at all the controls that were attached to my player and to my surprise, the FrameGrabbingControl was not on the list. then i tried the same thing with a Processor and got to the same point, the FrameGrabbingControl simply isnt there. I found in the forum that if i set the ContentDescriptor to null, the FrameGrabbingControl will be attached to the processor yet the problem for the player still remains as i need my users to be able to specify which frame they want to grab which they cannot do with a Processor. So i need to get it enabled in the Player.
I have copied my code, can you tell me if anyone has any idea how to get it working?
Thanks a lot

HellawaitsI am trying to capture screenshots of the video playing.Sounds interesting, and I would like to try and
help, but this code does not compile for me here.
(original words deleted in edit)
Can you prepare an SSCCE of this problem?
http://www.physci.org/codes/sscce.html
(..later)
OK.. I was a bit quick before, a couple
more changes and tweaks, but then I
was not only able to run this example
locally, but when I selected the 'add video'
I got to see the current frame pop up in
a JOptionPane.
This was using a simple .MOV* as source file.
Does this code not work for you?
* It is available here.
http://www.javasaver.com/testjs/jmf/anim/lunarphases.mov
If the code below does not work using the
media you are currently giving it, try the
simpler MOV file, or perhaps some of the
other media available here..

Hope that got your attention! Well folks hi there. I'm hoping you can help me out a bit on this one. I've got a JFrame GUI app with the following Components: 1 JLabel, 1 JTextField, 1 JButton, 1 JTextPane, and a menu system up top. It looks "about" like this:
| File Edit Help |
| |----------------------------------------| |----------------| |
| Enter URL | | | Print | |
| |----------------------------------------| |----------------| |
| ------------------------------------------------------------------------------- |
| | | |
| | | |
| | | |
| | | |
| | | |
| | | |
| | | |
| | | |
| | | |
| | | |
| | | |
| | ---------------------------------------------------------------------------- | |
|-------------------------------------------------------------------------------------|The problem is, with the JTextPane set as not 'enabled' 'setEnabled( false)', I simply can not navigate out of it using the keyboard Tab key (or any other for that matter, not that I'd want to use another key).
If I setEnabled( true), it's fine. But, as I said not if 'false'. I've tried requestFocus(), setNextFocusableComponent( Component), even grabFocus() from the JTextPane to try to go either forwards or backwards from the JTextPane to either the JButton or the JTextField, but it seems trapped in the JTextPane.
When I do printlns from the keyPressed and focusGained methods, it shows that the next JComponent - beit JButton or JTextField - gets focus, but it dosn't really (or I should say practically), since all keys at that point are rendered useless, and I need to break out with the mouse.
I did not look through the 1.3.1_04 (version I'm on) bug reports. Anyone know a solution to this? Thanks in advance.
~Bill1. It took a little time, but I recoded OUT all the other classes. You'll still need your own 'Readme.html' file and you own *.gif icon file, but that's it. Here's the code ... it is still - even beyond this pblm - in dev phase:
