Hi,
Does anyone know how to be able to use the iPAQs harware buttons and joystick in Suns Personal Java?
I moved a Tetris applet i have written for PC's to the iPAQ and it works except for the arrow keys that i use to control it with.
Any help would be greatly appreciated!

I have the same problem.
Does anyone know how to use the buttons of the iPAQ for your java applications?
Thanks

How to use hardware acceleration in Java 2D

Hi,
I searched in net and could not find anything clear on hardware acceleration using Java 2D/Swing.
To use the hardware acceleration, do I need to specify
-Dsun.java2d.opengl=true ? Is this must?
Without specifying this, Java 2D calls wont use hardware acceleration?
Kindly clarify. I could not able to find anything in net for this.
I am having ATI Radeon AGP card and using Linux as OS. I have installed the ATI driver. Now I need to know how to interact with hardware using Java2D/Swing.

it gives error message... how can � use struct model in java applets???
if you help me i will be greatfull....

� use import but it doesn't work.
i add: import renk; or import class renk;
how will � add import I assumed based on your initial post that the renk and benek classes were in the same file. Apparently you're saying they are not. So for another thing, make your renk class "public class renk", and add the "public" keyword to the 3 members of that class. Then if your code still doesn't see the "renk" class, it would just be that you don't have the directory that contains the compiled "renk.class" in your classpath.

To use the hardware acceleration, do I need to
specify
-Dsun.java2d.opengl=true ? Is this must?No. I've never seen that before. My assumption is that you'd do that if you wanted to make sure you're using OpenGL and not DirectX. Swing will make use of 2D hardware acceleration on it's own. Don't specify anything special.

How to use one button rollover symbol to create 100 graphically different buttons

I do know how to create a button rollover symbol.
I don't know how to make that button rollover symbol reuseable. I'd like to put 100 different images in 100 copies of the button. I'd rather not make new symbols for every button, since the rollover animation may change.
Symbol "Accessibility" allows the title to be changed for copies of the symbol. Does similar functionality exist for bitmaps used in the symbol?
Could the copied button bring in new graphics from the timeline in another symbol or a xml sheet?
Any help would be greatly appreciated. I've been following tutorials, except none of them cover this situation.
Thanks for your help!

Created in EA version 3:
I have 2 samples for you that are very similar.
1- uses the symbol with no image and loads the image as a background-image for the div.
https://app.box.com/s/co7uki3fm3b11a3o1xjw
2- uses an image in the symbol and replaces this image with a new one in the img (not div)
https://app.box.com/s/3ms92f5cv0mylspsi5uo
Choose what you prefer.
3. An example with more elements in the symbol directly on the stage instead of a container. use a container if you want to place the symbols in a specific rectangle div for example.

How to use one button to drive another button click

I'm trying to figure out a way to fix a bug in my application. The simple fix would be to have a single button that drives a MouseCLICK event on another button everytime the PlayBar in my application reaches the end of the screen and returns to its origin.
How would I achieve this? I have made a lot of headway since I last posted a question in the ActionScript 3 forum, which was only yesterday evening.
Thanks in advance,
markerline

The application is an audio application. It is like a drum machine sort of.
Currently there is a grid and whenever active cells get hitTest'ed by the PlayBar they become deactivated, the PlayBar returns to the origin, and when you relaunch the Play functionality the deactivated cells no longer play a sound.
I have a button which reactivates the sounds.
I also have a button which has a bug in it that loops the sounds.
To go around the looper button that has a bug in it I would like to use a Button "Z" which automatically clicks the "reactivate the sounds" button every time the PlayBar returns to the origin and the PlayBar will then continue to play and return to the origin in a looping fashion. If the Button Z is in an active state this looping will continue. To stop looping, click the Button Z until it is no longer in an active state and the PlayBar will then remain at the origin.

if my longMessage is smaller like one line then everything works fine, but as soon as my longMessage if greater than 254 it starts giving me -404. How do I work around or Is there any way to use host variable in Java?
All kind of help is appreciated. Any question then please email me at [email protected].
Thank you.

This is what you got to do to insert a larger value.
//Assuming that message length is less than 254+ 254 characters.
//If larger then run the update loop that many times.
String longMessage = "Blah blah ... ";
String firstPart = "";
String secondPart = "";
int messageLength = longMessage.length();
if (messageLength > 254)
     try
          firstPart = longMessage.subString(0, 253);
          secondPart = longMessage.subString(254, message);
     catch (IndexOutOfBoundsException e)
//In the first insert set the first 254 characters
ps.setString(1, firstPart);
int result = ps.executeUpdate();
if (result != 0)
       System.out.println("Insert sucessful ");
       if (messageLength > 254)
            //now update with the second part.
            static String UPDATE_SECOND_PART = UPDATE my.table SET LONG_COL = LONG_COL || ? WHERE KEY_COL = ?;
            ps2 = connection.getPreparedStatement(UPDATE_SECOND_PART);
            ps2.setString(1, secondPart);
            ps2.setString(2, businessId); //assuming that businessId is the primary key.
            int result2 = ps2.executeUpdate();
            if (result2 != 0)
                  System.out.println("Update sucessful ");
            else
                 System.out.println("Update failed ");
else
       System.out.println("Insert failed ");
}Hope this helps.

How to use a button in a required field

Hi,
this is my scenario:
1) In a Form I have two Blocks
2) In the first, I use a text Item for the customer code, with the required property set to true and with a trigger WHEN-VALIDATE-ITEM
3) In the second block, I use a button that call the 'show_lov' function in order to display the list of the customers.
If the focus is out of the first block, I can use the button without problems.
If the focus is on the customer code Item and I try to use the serch button, the alert message "Field required" is displayed and I don't be able to use the function in the button.
Exist a method in order to use my button when the focus is in the required customer item?
If Yes, how can perform this ?
I hope...
Best Regards
Gaetano

When you set Required = Yes, you're telling Forms not to allow the user to navigate away from the item until they enter a required value. That's the way Forms is designed.
If you don't like that behavior (and I'm one that doesn't), I rarely use Required = Yes. Instead, I write the code to check for a required value in the PRE-COMMIT trigger. If the item doesn't have a value, I set focus to the item, and then issue a RAISE Form_Trigger_Failure.
I'm sure there are other ways to do this, but that is just one technique.

How to Use Exec function in Java Code

How to Use Exec method
I want to Execute command
net Start "some service"
using exec method of runtime class
or i use some other way if suggest

Assuming you have read http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Runtime.html#exec(java.lang.String) already, I can only suggest to be more specific in what your problems are. If you are after just some example code, then download ftp://ftp.ebi.ac.uk/pub/software/textmining/monq/monq.tar.gz and have a look at the source code of monq.stuff.Exec. It does all those things which are necessary to keep track of a Process after it was created with exec.
