Uses & syntax of classes
hi friends,
I am making a chatting messenger using socket programming in java,I have some problem in establishing chatting session between two clients,where server just provide socket address of the c2 to c1,and then two client connect to each other and then send message without passing that message through server.But i have some problem doing these.
Will you please tell,is what i had tell above is possible,if yes then plz tell me how to do it;Secondly i learned about (class SocketImpl, SocketAddress,InetSocketAddress),but i dont know how to use it in my application, &will these class be needed in my application.Plz give some good link where i can learned about that classes.
please help me & thank you for suggession
You don't need to worry about SocketImpl but you do need to look at ServerSocket and the Java networking tutorial.

Model Binding and Calculated Field Syntax for "class" Attribute
Hi,
I tried to use the calculated field syntax from SAP UI5 to change the CSS class attribute of an element based on some model property, i.e., I wanted to change the class in the corresponding formatter function based on the currently bound value. However, my formatter function is not called. When I use the same syntax on a text attribute, it works.
I also tried to use normal property binding, but it did not work on the class attribute either (it just put class="{property}" in the rendered HTML).
Is there anything I missed or is it just not possible to use property binding and calculated field syntax for class attributes? Did anybody try something like this before?
I think it is a standard use case to change the CSS class based on some model property. So, if anybody knows how to do that, could you give a short example?
Best regards
SvenjaThey have a class property. At least, I can do the following in an XML view:
<Button
icon="sap-icon://add"
press="onButtonPress"
class="my-button-class" />
I would expect the following to work as well, but for me it did not:
<Button
icon="sap-icon://add"
press="onButtonPress"
class="{/customClass}" />
This renders the following HTML (cropped to the important parts):
<button type="button" class="sapMBtn {/customClass}">
</button>
It seems like the class attribute is something special although I don't see a reason why. Other HTML templating engines, for example, support things like that. -
Hi Experts,
I want to use Interface of Class object. But I'dont know how I use it (declaration,call,create etc.)
There are a lot of exam about using local interface. But I need from Global object.
Class : CL_TPDA_DIFF_STRUC
Interface: IF_TPDA_DIFF_SERVICE
Best regards.Firstly ; Your advice book tells the "General OO".
But I need "Only ABAP OO". The basic logic is the same. But syntax are different.
If there is a book about ABAP OO and syntax You can advice to me.
Secondly;
My code is below.
I created my interface success . But It give error at runtime. Error mesaage : 'Error during interprocess communication; Debugger will be closed . Message Number TPDA151'
DATA l_ref_diff TYPE REF TO CL_TPDA_DIFF_STRUC.
data : xyz TYPE REF TO IF_TPDA_DIFF_SERVICE.
data : p_var1 type TPDA_VAR_NAME,
p_var2 type TPDA_VAR_NAME,
lv_x type TPDA_DIFF_ATTR.
data : l_it_value_diff TYPE TPDA_DIFF_VALUE_DIFF_IT,
l_it_main_diff TYPE tpda_diff_main_diffs_it.
p_var1 = 'CLIENTDATA1'.
p_var2 = 'CLIENTDATA2'.
lv_x-maxhits = 100.
CREATE OBJECT l_ref_diff.
xyz ?= l_ref_diff.
xyz->init( ).
xyz->DIFF( EXPORTING p_var1 = p_var1
p_var2 = p_var2
p_diff_attr = lv_x
CHANGING p_it_value_diff_it = l_it_value_diff
p_it_main_diff_it = l_it_main_diff ).

Tracking Memory usage on iOS using the Stats class
I've been checking memory usage on an app I'm developing for iOS using the Stats class https://github.com/mrdoob/Hi-ReS-Stats ( http://help.adobe.com/en_US/as3/mobile/WS4bebcd66a74275c3-315cd077124319488fd-7fff.html#WS 948100b6829bd5a61637f0a412623fd0543-8000).
I added the Stats class to my project and redeployed and, yikes, memory usage reported in Stats creeps up (pretty slowly) even when there's nothing happening in the app (just showing a loaded bitmap).
To try and track down the issue I created a project with a test class that extends Sprite with just this single call in the constructor :-
addChild( new Stats() );
I deployed it to the device to check that it didn't gobble any memory.
But I was Suprised to watch the memory usage creep up and up (to approx 5) before some garbage collection kicked in and takes memory back down. I left it running and then it crept up again to over 7.5 this time before being kicked back down to just below 3.
So 2 related questions that I'd appreciate any feedback/observations/thoughts on :-
1 - Is this normal (i.e. memory creeping up when there's nothing other than Stats in the project) ?
2 - What is the best way to monitor memory usage within an app ? Is Stats good enough - is Stats itself causing the memory usage ?
All the best guys !Also see thread (http://forums.adobe.com/message/4280020#4280020)
My conclusions are :-
- If you run an app and leave it idle, memory usage gradually creeps up (presumably as memory is being used to perform calcs/refresh the display etc)
- Periodically the garbage collection kicks in and memory is brought back down
- This cycle could be in excess of 5 mins
Run with your real app and memory will increase and be released much more rapidly/regularly.
- It's probably worth performing initial checks by running on your desktop to iron out any initial problems -
How to use the Rectangle class to draw an image and center it in a JPanel
I sent an earlier post on how to center an image in a JPanel using the Rectangle class. I was asked to send an executable code which will show the malfunction. The code below is an executable code and a small part of a very big project. To simplifiy things, it is just a JFrame and a JPanel with an open dialog. Once executed the JFrame and the FileDialog will open. You can then navigate to a .gif or a .jpg picture and open it. What I want is for the picture to be centered in the middle of the JPanel and not the upper left corner. It is also important to stress that, I am usinig the Rectangle class to draw the Image. The region of interest is where the rectangle is created. In the constructor of the CenterRect class, I initialize the Rectangle class. Then I use paintComponent in the CenterRect class to draw the Image. The other classes are just support classes. The MyImage class is an extended image class which also has a draw() method. Any assistance in getting the Rectangle to show at the center of the JPanel without affecting the size and shape of the image will be greatly appreciated.
I have divided the code into three parts. They are all supposed to be on one file in order to execute.

How to trigger New page while using ALV with classes/oops?
Hi All
I am trying to print a report which has to show the data in two pages.
I am using ALV with classes/oops.
Though I am able to print the report but a new page is not coming. Whole of the data is coming in one single page.
Please tell me as to how to trigger a NEW PAGE while using ALV with classes/oops.
Please send some code samples also if available.
Thanks in advance.
Jerryusing sort option you can do it. in case of grid/oo alv class ALV you can view that only in print mode/preview mode.
in case of list you can view that directly.
sort-fieldname = 'FIELDNAME'.
sort-group = '*' "triggers new page
sort-up = 'X'.
append sort to it_sort. -
I found this class today which is really cool:
http://www.gskinner.com/blog/archives/2007/11/fire_effect_com.html
However, I've never used a public class before. I've been reading up on them all morning. I'll provide the code for it here as well. Anyway, the author also provides a sample application using the class; however, it's a bit different than what I've been reading. He doesn't call the class in his code;however, it seems he has the class in his library, which is news to me.
Anyway, the biggest thing I'm after is trying to design my own application calling this class and just hardcoding the fire aspects in my application. However, I'm coming up empty at every angle. Any help would be much appreciated!
Here's the class he created:

slider.x = 350;
slider.width = 170;
slider.y = 75+50*i;
slider.snapInterval = 0.05;
slider.value = 0.35;
fireFX[params[i]] = 0.35;
function handleSlider(evt:SliderEvent):void {
fireFX[evt.target.name] = evt.target.value;
(getChildByName(evt.target.name+"fld") as TextField).text = String(evt.target.value);
blueFlame.addEventListener(Event.CHANGE,handleCheckBox);
hideText.addEventListener(Event.CHANGE,handleCheckBox);
function handleCheckBox(evt:Event):void {
fireFX.blueFlame = blueFlame.selected;
obj.visible = !hideText.selected;
Thanks again.Looks like he has fireFX instance on the timeline. Most probably this instances symbol base class is com.gskinner.effects.FireFX
You just need to create a directory structure that reflects his package:
com/gskinner/effects/
where you place his FireFX.as
Or, alternatively, you can remove package path from the class header and place FireFx where all you classes (or your application) are:
package com.gskinner.effects {
to
package {
Then you will just need to instantiate the class. -
How to use two activex class objects in same vi
HI
I am using labview to read ECU data from INCA software .INCA providing COMTOOL API(incacom.dll). I am using ACTIVEX for communication between INCA & Labview. My problem is If I have used single activex class object I am able to read Inca version, getting the database path etc. If I have used two activex class in same vi (one to open Inca & other one is to read the folder structure) I am not getting output.I have attached snapshot for referance
Attachments:
activex1.JPG 114 KB
activex2.JPG 107 KBIt wasnt in the first two images you posted, or I couldnt see it anyway! That was the only reason.
Did you try the database block on its own, just to confirm that it is working?
Beginner? Try LabVIEW Basics

How to use the implementation class in propetty pallete
Hi,
I am using forms 10g....I have to insert horizontal scroll bar in text item..
I have only class files instead of jar files ...how cani place the class file instead of jar file...
How to use the implementation class in property palette to display the PJC
Thanks,
Ansaf.The Implementation Class must reflect the full name of the class. For instance, if the full class name is : xx.yyy.zz.class_name, then put this in the Implementation Class property of the corresponding item.
Also, the class must be stored in the equivalent directory structure, so that, in my example: <DEV_HOME>/forms/java/xx/yyy/zz

Can you use two tax classes in the same payroll run?
Hi,
I have a wage type that is currently set to Tax Class 1 (fully taxed) for processing class 71, I need to change it to tax class 7 (Withholding and SUI only) and have it computed as part of the regular payroll run and also by itself using offcycle.
When I have it set as Tax Class 1, all is well, when I change it to tax class 7, I get the error...
BSI Messages and Status 4101 CAN NOT PROCESS DUPLICATE RESIDENT STATE FED
This is the first time we're using this tax class and I think i have it set up correctly in the tax model but am not for sure.
Any suggestions? I'd really appreciate some guidance as I've looked
Thanks!
Stephanie AbrahamsonI think you should not change the PRCL 71 from 1 to 7 wide open. Start it with begin date of pay period you want and keep the history with PRCL 71 1.
As well check the config of tax model.

Than how can i get java class by using it's class file?
Hi
After compilation of a java program, it creates a class file.
After getting class file suppose class file has been deleted.
Than how can i get java class by using it's class file?
Thanks in advance.get a decompiler and run your class file through it--I'll assume you want the source code back and that you are not trying to recover a missing class file by attempting to use the class file that is missing--if it's missing, then I've not a clue on how to get it back by using what is already missing.
BTW: many of your compilers have source control--if it does, just restore your missing file.
