Custom Windows and Frames in Java - Help

Hello, I'm begining a Java class in school and Ive been wondering how to get rid of these boring windows. For example I want to turn something like this:
to something like this:
I realize theyre 2 different programs. Im simply asking how I may draw and implement my own frames on windows along with background images/colors.
Thanks in advance~

Have a look at http://www-128.ibm.com/developerworks/java/library/j-iframe/ which allows you to override all of the decorations associated with frames.

Perform Hamming window and FFT with Java

Hi all,
I am trying to apply Hamming window on my lengthy sound data soundSample[1000] with window length 100. Then proceed with FFT.
And i found that java does have the package for Hamming window and FFT. As below,
http://code.compartmental.net/minim/javadoc/ddf/minim/analysis/FFT.html
http://marf.sourceforge.net/api/marf/math/Algorithms.Hamming.html
But i hardly find an example that illustrate how to use the package in a java program. So no idea how should i use the method in package.
Please advise and appreciate if reference is provided.
Thank you.

Hi,
I have spent sometimes to study and do the coding for FFT on audio samples.
My project is to study the FFT working by performing the FFT on audio sampled data.
After this is done, then only proceed to extract the pitch value in the audio data.
Below is the coding that i have done by referring to the provided steps:
In my main, i call this method and past the retrieved sampled sound data to this method.
public static void Analyze(int[] soundSample,float sample_rate ) {
        int N = (int)sample_rate/5;
        int Number_Sample = soundSample.length;
        Complex[] fftBuffer = new Complex [2*N];
        Complex[] fftResult = new Complex [2*N];
        Complex [] lastN = new Complex [N];   // The array to save the last N sample
        int delay = 0;
        double delta = 2*Math.PI/(2*N);
        // I have no idea how can i convert my sample array to double so that it will be in the range of [-1,+1]
        while(delay <=soundSample.length){
            //Extract the 2N sample for FFT analysis and convert the data to complex number.
            for (int z=0; z<2*N; z++){
                fftBuffer[z] = new Complex(soundSample[z+delay],0) ;
            for (int i=N-1;i>=N/2; i-- ){
                lastN[N-1-i] = fftBuffer;
for (int z=0; z<2*N; z++){
fftBuffer[z] = fftBuffer[z].times(0.54-0.46*Math.cos(z*delta));
fftResult = FFT1.fft(fftBuffer);
delay = 2*N + delay;
1) I was trying to perform FFT with 2N samples then keep on looping the FFT method until 2N reaches the ends of sampled data.
But the FFT that i am working with is radix 2... It doesn't work with my 2N samples... Please teach me how should i work out FFT regardless the number of sample?
2) The hamming window coefficient i m using is based on http://www.mathworks.com/help/toolbox/signal/hamming.html . I am working on index [0:2N] ..
Is it appropriate?
3) According to your No1 steps, the acceptable frequency resolution is 5Hz. May i know what is this representing? And is it application for most of the FFT application? How can i determine the frequency resolution that i should used in my project?
Sorry for late reply as i was trying to work out the thing..
Hereby attach to your the my coding.. and hopes to have your guidance and tutorial how to extract the pitch for recording audio file with Java.
I have done the pitch extraction with MATLAB.. but Matlab as built-in FFT function...
So i m now get stucked how to perform FFT on audio sound sample regardless the N value of sound sample for FFT buffer.
Many thanks for your former advise... and
Looking forward for your replies again.
Happy New Year 2011 :)

Executing WINWORD from both Windows and linux using Java

Dear All,
I have a problem when trying to use Runtime class to execute a winword document. My code is as follows.
Runtime r= Runtime.getRuntime();
try{
r.exec("rundll32"+" "+"url.dll,FileProtocolHandler"+" "+"WINWORD"+ " "+"file://C://welkom.doc");
catch(Exception ex){
System.out.println("Unable to open the doc file:"+ex);
When I execute this swing application with the above, the program is unable to open the specific file. And it says "Problem with the short cut, unable to open the file". When I run the program without the file name, it opens a new doc file.
Attn: what I want to do here is I need to open the winword file from both windows and linux. So I cannot use the relative path of the WINWORD.exe file.
Can anyone help me?
Thanks in advance.
Regards,
Bala

If you take a look at the api, there's an exec(String[]) method. This is the one you should use when calling a command with multiple parameters.
so something like...
String[] cmd = new String[] {"rundll32", "url.dll,FileProtocolHandler", "WINWORD", "file://C://welkom.doc"}
r.exec(cmd);

Special double quotes and apostrophes in java help

We are writing help for an application and using doctor help to generate it. The help is written in Word and converted to html. Word however, converts all the " characters to those "squiggly ones" which point towards the word they're quoting.
When we viewed the generated help with java help those squiggly were not rendered. They are rendered as a square which means java help does not understand them.
I'm sure someone else must have encountered this issue.
Please can you tell me how to successfully render the squiggly double quotes in java help?

You need the following encoding for those characters:
“
”
using an xml encoder, e.g. xmlenc solves this issue, otherwise you must do it manually.
But I have a related problem. When characters in the XML file are encoded
they are only displayed correctly if some non encoded character follows.
When there are two successive encoded characters then only the first one
is displayed correctly. Putting a whitespace in between them displays both
characters correctly, but with the whitespace in between.
I guess there is an issue with the XML parser. Changing the encoding of the XML file does not help.
example: TOC.xml file (displayed correctly in IE)
<?xml version='1.0' encoding='ISO-8859-9' standalone='yes' ?>
<!DOCTYPE toc PUBLIC "-//Sun Microsystems Inc.//DTD JavaHelp TOC Version 1.0//EN" "http://java.sun.com/products/javahelp/toc_1_0.dtd">
<toc version="1.0">
<tocitem text="images "/>
<tocitem text="ĞĞRENCİ MODÜLÜ " target="index"/>
</toc>
Any ideas?

Fonts in Windows and Fonts in Java

Hello,
Say I have in my app:
String string = "\\u09A1";
I want to display this in my app. I can call:
GraphicsEnvironment.getLocalGraphicsEnvironment().getAllFonts();
I can then iterate through these and find out which ones can display this unicode character using,
font.canDisplayUpTo(string);
My question is, are these the fonts that Java can display (from charsets.jar) or the ones installed in Windows?
I would like to be able to get lists for both of these.
Any ideas?
Cheers,
Jim

Thank you. I did read that. I was not talking about drawing text in 'Hello World' alike applets/programs.
I should give an example:
I would like to print 'H' in Tahoma, 72, Bold (Windows format) at (100, 200).
Font sizes:
In Windows font size is 72 pixels.
In Java this is equal to 96 points (72 px * 96 (scr resolution for Toolkit) / 72 (pixels per point).
Real height in Windows and Java will be 64 px.
That's fine. For some fonts this does not work.
Positioning. See example above.
According to the article you refer to in java we should use y-coordinate 200 + 72 (font size) = 272.
In fact we have :
Java text 14 pixels below than expected.
Similar things happen to other parameters Weight, Styles, etc.
I do use AttributedString and TextAttribute classes to render text
Thanks in advance.

Setting file permisions ,group permission on Windows and unix from java

Hi
i am trying to set up file permissions through java on unix and windows operation sysyem
.I don't want to use shell scripts .
thank you for your help.

HI BIJ001,
Thanks for reply.I am paling to use
1)First i am detecting operating system
2)if it is UNIX->calling unix scripts from JAVA
2)if it is WINDOWS ->calling Bat scripts.
But attrib command in windows does not support FIle Gropu permssion like unix(chmod 777 filename).
Do yoou have any experience in .bat sctipts on file permission.
Let me know .Again thank you for reply.

Custom components and binding ... help !!

hi, i have created a component that wraps the TextInput
control with its own set and get text methods, but it does not work
well with the Binding mechanism.
here is the code:
<vc:myTextInput text="{str}" y="8" tabIndex="0" x="100"
id="in1"/>
and the binding
<mx:Binding source="in1.text" destination="str"/>
does not update the str field.
can any one tell me what i did wrong / forgot to add ??
cheers,
Jaimon

hi as ntsii said i am looking for a two way binding meaning
that for every change in either of the controls, will be seen by
the other...
i am guessing that in order that the custom component work
with the binding mechansim a certain API must be implemented of a
mechanism that dispaches the right event ... but i could not find
any ducomentation
any help would be blessed ... happy new year
Jaimon

When i go to export i cant click the export button. i have to move the window as high as i can then drops down. try to resize the window and moves itself. please help

i cant export the window moves itself and wont resize. what do i do?

It sounds like you've installed language packs instead of dictionaries, because there's no South African dictionary available.
* https://addons.mozilla.org/firefox/language-tools/
This is the English (British) add-on you need installed to have a dictionary in that language:
* https://addons.mozilla.org/firefox/addon/british-english-dictionary-/
After you've installed it, right-click a text field and make sure the "Check Spelling" option is enabled. Then in the Language submenu you can find "English (United Kingdom)". You can use the following add-on to automatically switch the language for the spell checker.

I have both an iPod and Ipad 2. Latest I have sync. ipod. Now when I want to sync. iPad 2 in iTunes its only iPod mentioned in sync. window and it does not help to connect iPad. its not shown in iTunes. What to do next?

I have both an iPod and iPad 2. Latest I have sync. iPod and now I want to sync iPad, but iPad is not shown in iTunes when connected. I have the latest iTunes version.

If your computer starts image capture or some other camera software you should be able to quit that and then your iPad will show up in iTunes. Mine does this all the time.
The preference on what to start up when a "camera" is connected is found in Image Capture. So start Image Capture. It's in the applications > Utility folder. Then look for preferences. In my version it's in the lower left corner. Select None or Nothing and quit the program. From then on your iPad should show correctly in iTunes. But you will most likely have to start your smear software manually when you do connect a camera to your computer.

Code Sample: Easy RFC Lookup From XSLT Mappings Using a Java Helper Class

Hi everyone,
This is just a shameless plug for my article: <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/05a3d62e-0a01-0010-14bc-adc8efd4ee14">Easy RFC Lookup From XSLT Mappings Using a Java Helper Class</a>. I hope you're interested in reading it, and I welcome your comments in this thread.
Kind regards,
Thorsten

Hi Stefan. Thanks for your post. I have already done that. It still does not work. As a base for my java helper class I have usesd Thorstens code.
The problem is quite confusing. I will try to ouline both issues here.
First of all, when try to test from within the Operation Mapping, I always get a java error saying it cannot find the communication channel (it is there and working because I have tested it with the RFCLookup in graphical mapping). I have found a way to work around this, and that is to uncheck the "Use SAP XMLToolkit" checkbox --> switch to test tab, enter my ReceiverService in the parameter tab (header parameter) --> switch back to Definition tab, check the "Use SAP XMLToolkit" checkbox --> switch to Test tab and run the test. Then the XSLT and call to java helper class will work. Of course this is not really something you want to do all the time. Maybe there is a bug.
Secondly, it never works when I try to do it "live". I am using a file adapter to pick up one file, convert it and a file adapter to drop the converted file. I get the following error code in SXMB_MONI.
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>

Using an XSLT without a call to a java helper class, works just fine.
I am totally at a loss here. Any more input would be much appreciated.

For printer LaserJet Professional CM1410 any chance to set printing password for windows and MAC

Dear All
for printer LaserJet Professional CM1410 any chance to set printing password for windows and MAC?please help?

What Windows OS are you using? Are you networked?
If you are networked, you have to setup your file and print sharing options in order to require password assess. If you are just trying to control specific files from being printed, you can do that, too.
If you are just trying to control the amount of printing off of a single PC with a printer, you could setup different accounts for each user and limit their access.
Some of the commercial printers can have password options, but I do not find any password options for the CM 1410, other than what I provided earlier.
If I have been helpful, a Kudo is always appreciated.

Go to System Preferences - Accessibility - Voiceover - turn off Voiceover. The shortcut is command-F5, so possibly you pressed that accidentally.

Why CreateNewFrame() returns as NULL after successful created 136 child frame window and trying to create 137th child frame window in MDI application

I am working on MDI application which was developed in VC++ in VS 2012. When my application is launched, it will display a Tree. Under a tree there are 254 nodes. Basically
these nodes data are read from Configuration xml file and loaded into the Tree. By double clicking on each node, first it will create object for document class ( By calling CreateNewDocument() method) after that member variables for that
document class will be initialized and then it will create the new frame window (by calling
CreateNewFrame(pDoc,NULL). New child frame window will show under Main window to the user.
User able to see the data from child frame window.
Similarly by double clicking on each node it will create another object for the same document class and new child frame window will be opened for that node. Each child frame window runs
in different data and showed under the Main window.
Existing requirement by double clicking on each node, node data shall show in separate child window and there is no requirement for all 254 child windows opened simultaneously.
But current requirement is , all 254 child windows shall open simultaneously by double clicking on each node one by one.
In debug mode I have tried double clicking on each node. I able to open up to 50 nodes. After 50th child windows are opened, I unable to access to the application
(Unable to open further node data window since application is getting hanged).
Each child window is having tree, multiple splitter window and some additional controls (static text, ...).
Same I have tried in release mode, I able to open up to 136 child windows. After that the application fail to create the new frame window in VS 2012. i.e CreateNewFrame() return
NULL after successful created 136 child frame window. Debug purpose I have added the code to retrieve last error code by calling GetLastError() method. I got the value as "0". By closing any existing child window then I able to open remaining nodes.
At any point of time I can reach maximum of 136 child frame window that can be opened under Main window. Failing to open all 254 child frame window
simultaneously, currently I fail to meet the current requirement.
current Requirement is all 254 child frame window are opened simultaneously. Please let me know what may be the reason fail to create new frame window after 136 frame window that are
opened already. In Microsoft site, mentioned that there is no limitation for creating frame window in MDI application. I have tried another sample MDI application having limited number of controls, in which I able to create "n"
number of child frame windows. why not able to create more than 136 child frame window in my actual application?
Is there any possibility by changing project settings allow me to create 254 child frame window??
Code Snippet as below:
CDiagBaseDoc * CDiagBaseMDocTemplate::OpenDiagView( ...)
     CDiagBaseDoc* pDoc = NULL;
    if (pDoc == NULL)
        pDoc = (CDiagBaseDoc*)CreateNewDocument();
    if ( pDoc )
       CFrameWnd* pFrame = NULL;
       if (bAlreadyOpen)
              // If Child frame window already opened, then handling the code here.
     else
           pFrame = CreateNewFrame(pDoc, NULL);
           if (pFrame == NULL)
              ASSERT(FALSE);
              delete pDoc;       // explicit delete on error
             pDoc = NULL;
          ASSERT_VALID(pFrame);
          if( pDoc != NULL ) //VS2012
             if ( !pDoc->OnNewDocument() )
                TRACE0("CDocument::OnNewDocument returned FALSE\n");
                delete pDoc;       // explicit delete on error
                pDoc = NULL;
                pFrame->DestroyWindow();
                 pFrame = NULL;
       if (pFrame)
           InitialUpdateFrame(pFrame, pDoc);
           ShowWindow( pFrame->GetSafeHwnd(), SW_MAXIMIZE ); //when opening node for the 1st time, maximize it
}<o:p></o:p>

Hi MuruganK,
Have you checked how much memory your application used? You could check it by Task Manager. Maybe your application reach Memory Limits for Windows.
https://msdn.microsoft.com/en-us/library/windows/desktop/aa366778%28v=vs.85%29.aspx?f=255&MSPPError=-2147217396
Is it possible that there are some memory leaks in your application? It would better if you have made a simple sample to reproduce and narrow down this issue.

Shu
