Displaying images in canvas one after another
Hi all,
I have a problem displaying images in canvas one after another. I am using for loop and when i run the application, all images run back in the and only finally only the last image gets displayed in the emulator. I also used thread.sleep(). But it din't work.
Here is my code:
// A canvas that illustrates image drawing
class DrawImageCanvas extends Canvas
Image image;
public void paint(Graphics g)
int width = getWidth();
int height = getHeight();
g.setColor(0);
g.fillRect(0, 0, width, height);
String images[]={"paint_2.PNG","radha.PNG","cute.png","design.png","flowers.png"};
for(int i=0;i<images.length;i++)
image = null;
System.out.println("/"+images);
try
image = Image.createImage("/"+images[i]);
catch (IOException ex)
System.out.println(ex);
g.setColor(0xffffff);
g.drawString("Failed to load image!", 0, 0, Graphics.TOP | Graphics.LEFT);
return;
if (image != null)
g.drawImage(image, width/2, height/2, Graphics.VCENTER | Graphics.HCENTER);
try
Thread.sleep(5000);
catch(Exception ex)
System.out.println("the exception is.."+ex);
Help me and Thanks in advance.
See the code below : prefer the use of a Timer and a TimerTask instead of Thread.sleep().
showNotify (from Canvas) is used to launch the timer.
import java.io.IOException;
import java.util.Timer;
import java.util.TimerTask;
import javax.microedition.lcdui.Canvas;
import javax.microedition.lcdui.Graphics;
import javax.microedition.lcdui.Image;
public class DrawImage extends Canvas {
Image image;
String images[] = {"img1.png", "img2.png", "img3.png", "img4.png", "img5.png",
"img6.png", "img7.png"};
Image[] tabImage;
int imageCounter = 0;
public DrawImage(){
try {
tabImage = new Image[images.length];
for (int i = 0; i < images.length; i++)
tabImage[i] = Image.createImage("/" + images);
} catch (IOException ex) {
ex.printStackTrace();
public void paint(Graphics g) {
int width = getWidth();
int height = getHeight();
g.setColor(0);
g.fillRect(0, 0, width, height);
image = tabImage[imageCounter];
if (image != null)
g.drawImage(image, width / 2, height / 2, Graphics.VCENTER | Graphics.HCENTER);
else{
System.out.println("null");
g.setColor(0xffffff);
g.drawString("Failed to load image!", 0, 0, Graphics.TOP | Graphics.LEFT);
protected void showNotify(){
Timer t = new Timer();
t.schedule(new PhotoSwitcher(), 5000, 5000);
private class PhotoSwitcher extends TimerTask{
public void run() {
if (imageCounter < images.length - 1)
imageCounter++;
else
imageCounter = 0;
repaint();
I hope this will help you !

How to play two presentations from the DMP one after another and looping
Can anyone help me on this.I want to play two presenations one after another and looping from the DMP.
Semuhtu,
The easiest solution for looping two or more DMD presentations
is to create a nested playlist within DMD. You simply
create a master presentation and add a playlist to this
presentation. Add the desired presentations to this playlist
and then schedule or send the Action to the DMP(s) to play
the Master Presentation. The 2 or more child presentations will
play and loop until you stop it manually.
Summary of Tasks
* Using DMD create Presentations (2 or more) that you would like
to display on the DMP-Display(s).
* After the presentations are created, you will need to find out
what the URL addresses are for each presentation. Using the
"Actions" drop down on the DMM-DMP Manager screen, you select
a DMP and send the Presentation to the DMP. Once the DMP displays
the presentation, access the DMP-DM Web admin page and copy the URL
address in the "Startup URLs-->Browser" field. Repeat this process
for each DMD presentation that you want to loop.
For example:
http://dmm.company.com:8080/xTAS-core/appgen/clad/clad_95_.htm
http://dmm.company.com:8080/xTAS-core/appgen/clad/clad_96_.htm
and so on...
* Another parameter or variable that you will need to find out is
the duration of your DMD presentation(s). Some Presentations may be
a slideshow of images and some may contain videos. Your will need to
play each presentation on the DMP to determine the duration length of
each presentation that you will add to the looped playlist.
* Create a Master presentation using DMD. In this presentation, you will
create add a "Playlist" to the presentation by selecting the Playlist
button-drop down. Select "All Media Types" and a Playlist object will
be added to the Master presentation.
- Double-click on the object to add content
- Select "Add URL" button in the Playlist Content window.
- Fill in the required fields (URL Title & Link) in the "Add URL"
window. Repeat the process for each presentation that you want
to add.
- Set the Duration for each item in the Playlist. Select the Item
in the list and then DOUBLE-CLICK on the "Planned Duration"
field and edit the time to desired duration. Repeat process for
each item.
- Save Master Presentation
* Schedule or use the "Actions" drop down on the DMM-DMP Manager screen
send the Master Presentation to the DMP(s). The Playlist will play and
Loop after the last item in the Master Playlist.
If this answers your question, Please take time to mark this
discussion answered & rate the response.
Thank You!

When I try and open Microsoft Word 2011 documents on my IMAC they start opening one after another at a rapid speed and I can't stop it. I reboot and same thing happens. The documents open in rapid succession on their own and don't stop until I force close or after maybe 100 or more open I start getting the following message for each document attemting to open "This document could not be registered. It will not be possible to create links from other documents to this document" and then in paretheses the name of the document. After I click okay another trys to open. Any suggestions?
If you had multiple documents open and quit the app without closing all of the docs first, it will open them again when you launch the app. Open Word, and then close all the documents, you may be asked to save the document, if the document was already saved but you made changes to it before you quit the app, you may need to save the changes first, shorcut ( command and s keys). After you close all of the documents then quit the app and restart the computer. See if this works.

Playing movies in Front Row one after another automatically?
I have a number of short video clips that I can watch with Front Row. However, every time a clip ends, I have to go and click “play” on the next clip and this is annoying. I am wondering if there is a way to make movies play one after another without stopping. Thanks for the help!
David,
Thanks for the help. I'm still thinking there must be SOME way to pull this off. It seems like Mac's can do just about anything if you take the time to figure it out. Why wouldn't the people who designed Front Row not add this feature? It doesn't make any sense. There has to be a way. Anybody else have any ideas? -

How do i play two sound file one after another
Hi All,
How do i play two sound file one after another using single AudioClip Component?.
Advance in thanks
ManivelAudioClip gives you very little control over what happens to the sound, it also isn't capable of playing long clips or waiting until a clip ends. It will play multiple clips over top of each other.
To do what you want you should use the facilities of javax.sound. Here's a post with an example: http://forum.java.sun.com/thread.jspa?forumID=513&threadID=450768
There is also a tutorial, but its example fails for long clips. -

I know this is possible, I'm not sure how to go about it using Oracle's Scheduler. I simply want to create a special "queue" that I can submit jobs to which will run one after another. After they run, then then are gone. There many be no jobs at anyone time, and then at other times I may submit 10 jobs to the queue. Currently when I submit jobs they all run parrallel, this is not what I want. I guess I don't understand why Oracle calls it a Job Queue when all my jobs run in parrallel and not in a queue as the name implies.
This is not say that I don't have other jobs which I would not want to send to this "queue". In other cases I would just want to submit the job and let it run right away and not wait on anything.
I'm currently using the DBMS_JOB package, which I'm pretty sure won't let me do what I want.
Any help would be greatly appreciated.
Thanks,

Invoking 2 SQL statements one after another?
Hi,
Is it a good idea to invoke to 2 SQL statements one after another using the same connection & statement object? Some thing like this:-
method(){
String insertSql="insert into employee(Name,Age)values(?,?);
Connection conn=null;
PreparedStatement pst=null;
int insertRows=0;
ResultSet rs=null;
try{
conn=getConnection(); //will get the connection object
if(insertRows==0){
pst=conn.preparedStatement(insertSql);
pst.setString(1,"Jason");
pst.setString(2,"30");
insertRows=pst.executeUpdate();
conn.commit();
if(insertRows>0) {

//retrieving the data from the same table

Here one more thing is that i want the insertSQL statement to be invoked only once that is in the beginning and the next time the method() is called it should skip the insert block and should only retrieve the data using "select * from employee". How to do it? I tried with few options nothing works.. Please do provide a solution for this... It is really urgent.
ThanksIs it a good idea to invoke to 2 SQL statements one after another using the same connection & statement object? I think what you're asking is if you need a new Connection and/or Statement object for every query. The answer is no. In fact, most applications pool Connections so literally thousands or millions of queries are done in the lifetime of a Connection. You can reuse Statements and PreparedStatements as well as long as you intend on executing the same query.

Songs Skip Forward One After Another/Sporadic and Out of Nowhere
I have an older IPOD 40g that skips through songs, one after another, without playing anything, and seems to do it in any mode, especially in overall Shuffle mode. I have the "shuffle Songs" feature on, but other than that, it has a pretty standard set up.
I have restored to the defaults, last week, and it started doing the wierd stuff again today.
Sometimes I have a hard time getting it to unfreeze and reset as well.
I appreciate any help.Have you tried Party Shuffle? If you control click on a track, you can choose "Play Next In Party Shuffle". I often listen the way you're describing. I start listening in Party Shuffle (which I have set to select from a specific playlist). When I am reminded of another song, I select the song and then choose Play Next in Party Shuffle. And so on.
As for your second question, you could try moving your entire short playlist into Party Shuffle. Once that playlist was done, Party Shuffle would revert to it's normal selection criteria (you could set it to pull from your entire library or a specific playlist). Music would keep playing.
Can you tell I like Party Shuffle? -

How can I make my movies to play one after another automatically?
I couldn't find the settings to play all my movies one after another.
Any idea?Given the number of threads bemoaning the lack of such features (mostly for music videos) and countless enhancement requests sent here:
http://www.apple.com/feedback/appletv.html
..and the lack of the facility being added in over a year make me think it's unlikely to ever happen but I'd love ot be proved wrong!

Execute functions one after another
I would like to make a function that could execute other
functions
execute the one after another - in a manner that the next
function is executed only after the one before has finished its
task
I have been thinking about how to achieve this but haven`t
come up with anything good.
If you have any ideas please share
Thanks in advancehey,
what you want to is no problem at all. you just need to have
conditional statements within your main function that tell it when
to execute your other functions.
here is an example: -
Movies play one after another automatically?
In IDVD 8...can individual movies automatically play one after another without having to return to the menu to reselect the next movie and clicking on it?
I have 7- 3 min. movies I want to play together ...one after another...automatically in idvd08.If I had $5 for every time that has been asked...
It can NOT be done in iDVD. It can be done in DVD Studio Pro. -
Calling 3 different movies by one click, One after another.
Hi,
I have 9 small movies. I want to make a combo box and,
provide 3 options to choose from. But each option should call 3

to stream one by one to save bandwidth and delay. Following is the
option for calling one movie by choosing one option but I want to
start 2nd and 3rd movie without user interference. How do I do
that?
