SetBounds method is not working - settings change after Applet paint()
Hello,
I'm creating an applet with a scrollbar on it. I'm using Scrollbar.setBounds to set its position and dimension. These values are correct at the end of the init() method, but when the paint() method starts executing, these values have changed!
Here's my code :
import java.awt.Graphics;
import java.awt.Scrollbar;
public class testSetBounds extends java.applet.Applet {
Scrollbar sb;
public void init(){
sb = new Scrollbar(Scrollbar.HORIZONTAL, 0, 1, 0, 270);
sb.setBounds(10, 200,300,10) ;
this.add(sb);
System.out.println("sb.getWidth() " + sb.getWidth() );
System.out.println("sb.getBounds().x " + sb.getBounds().x ) ;
public void paint(Graphics g){
System.out.println("paint...") ;
System.out.println("sb.getWidth (at start of paint()) " + sb.getWidth() );
System.out.println("sb.getBounds().x " + sb.getBounds().x ) ;
System.out.println("sb.getMaximum() " + sb.getMaximum()) ;
<html>
<body>
<applet code="testSetBounds" codebase="classes" width="300" height="350">
</applet>
</body>
</html>
The output I get on the Java Console is:
sb.getWidth() 300
sb.getBounds().x 10
paint...
sb.getWidth (at start of paint()) 50
sb.getBounds().x 125
Can anyone tell me what's going on?
How to make my scrollbar remain in the position and with the dimensions I specified?
Thank you very much.
The layout manager is setting the bounds. If fo some obscure reason you want to do all the layout yourself then -

REP-51018 -- cookie method is not working :(
Trying to invoke a simple report from a simple form by using web.show_document()
if I pass the userid=x/y@z then it work fine
if I try to use the cookie method as defined in the OTN whitepaper "Secure Web.Show_Document() calls to Oracle Reports", I am bumping to the REP-51018 error.
Tried the metalink and found primarily 2 documents, one (note#279938) is suggesting using
SYNCHRONIZE; prior to invoking the WEB.SHOW_DOCUMENT(...), which I did - not worked,
then I read the document (#309652.1) which tells that the cookie method will not work if not using fully qualified domain name -- I have a fully qualified domain name and I can see in the browser cookie settings that the domain is set correctly.
I also edited the basejini.htm and basejpi.htm files and added the suggested entries as shown in the same OTN whitepaper (page #9). And recycled the entire iAS server after all the editing (reports.sh, formsweb.cfg, etc).
I can see the cookie is saved on the client browser and the userid is displayed in the JInitiator control window.

The only thing I can see is this line:

What is wrong with this cookie method? What I am doing wrong?
Any input is appreciated very much.

Instance Dependent Public Method is not working for Workflow
Hello Experts,
I have made Custom class for a workflow. This class is triggering the WF fine but the problem is while trying to execute a WF task which contains a Instance Dependent & Public method its not working , the WF task is not processing though I'm passing the instance of the class properly from WF to WF task . When I'm changing the method to Static & Public then the workitem is executing perfectly. Can you please help & suggest the way to find the problem ?
Thanks & Regards ,
JeetAre you absolutely sure that you have the instance of the object in the workflow container? Open the technical log the see if the object instance is there - or is the container element initial (or "not set")?
yes it is instantiated properly no error over there.
What about if you test the method directly in SE24 (as an instance method)? Is it working then? If you can make it work in SE24 as an instance method and you are sure that the instance exists in the workflow,
I have checked the class in a stand alone run in this case also it runs fine as before.
The obvious question of course is that have you implemented the IF_WORKFLOW interface methods (the two first ones).
it is coded like below
BI_PERSISTENT~FIND_BY_LPOR
create object result
type
(lpor-typeid)
exporting
ip_key = lpor-instid.
CONSTRUCTOR
me->m_KEY = ip_key.
me->m_por-catid = 'CL'.
me->m_por-typeid = CL_ZZZ'.
me->m_por-instid = me->m_key
BI_PERSISTENT~LPOR
result = me->m_por.
Main confusion is Method is working only if declared STATIC & PUBLIC but not for the INSTANCE DEPENDENT & PUBLIC. -

Hi,
Does the issue happen to all users? What’s your IE version? Is there any error when you access OWA 2007 in IE?
Please click Compatibility View settings in your Internet Explorer. Then, add the OWA site to the list of sites to be viewed in compatibility view and check whether the issue persists.

RSS not working in Mail after MobileMe instal
The title pretty much says it all "RSS not working in Mail after MobileMe instal" The names of the RSS feeds are still there but all have the triangle error message beside them.
you may have already tried this but in the mailbox menu at the top, try to take all accounts offline then take them all back online again. if that doesn't work you can always do a rebuild which is kind of a pain, but it usually does the trick.

Auto tab focus method is not working in iOS devices please share the ideas why its not working?
Auto tab focus method is not working in iOS devices. Please share the idear i am facing this issue while developing code for devices.
Hi there,
I can confirm this bug.
Not sure if this info is relevant, but this is my experience:
I am on the FIDO network, and so are two other people I know.
We all tried blocking numbers, and calls ring right through. Text messages are blocked successfully. (never tried facetime)
I also tried a ROGERS device running IOS7, and was successfully able to block my phone call from ringing through. HOWEVER, my call was forwarded to their voicemail, I was able to leave a voicemail for the person, and they did get an alert that they had a new voicemail.
I have not yet had a chance to test this on Bell, Telus, or any other carriers.
Spoke to Apple, and they advised me to do a hard reset (hold both buttons to shut off and reboot the phone), and if that fails to do an iOS restore.
I have yet to try this, but hopefully someone will have a better solution. -
Repaint() method is not working in MAC IE
Hi All
why repaint method is not working in MAC IE ? What i am doing is in one class which is inheriting Canvas class getting the keybord input then adding it to main applet.
Please help me i am trying it for whole week and i couldn't find any solution. I didn't put my code but if anyone is willing to help me i can post it.
Thanks in advancs
ShanHi
Thanks for your reply. Actually i wrote simple applets and those are working well.
So i did debug the code and i found that when i am running the following code in Apple MAC IE, nothing is happening in handleEvent method. Especially it is not going into the if statement (if (evt.id==401)). here i am checking for KEY_PRESS. I also tried with keyDown method but same problem in MAC IE.
I am pasting the code that is giving me problem.
import java.awt.*;
import java.applet.*;
public class testApplet extends Applet
public void init()
setLayout(new BorderLayout());
editableArea = new EditableArea();
editableArea.setBackground(Color.yellow);
add("Center", editableArea);
EditableArea editableArea;
import java.awt.*;
public class EditableArea extends Canvas
String s = "";
public boolean handleEvent(Event evt)
if (evt.id==401)
if(evt.key >= 32 && evt.key <= 255)
char c = (char)evt.key;
s = s + c;
repaint();
return super.handleEvent(evt);
public void paint( Graphics g )
g.setColor(Color.blue);
g.drawString( s,5,15);

Why the drawLine() is working only inside the paint method??
BufferedImage image = new BufferedImage(800,500,BufferedImage.TYPE_INT_ARGB);
Graphics2D g = (Graphics2D)image.getGraphics();
public void paint(Graphics g)
g.setColor(Color.black);
//Here, the drawLine() method works
g.drawLine(50,0,50,150);
public void paintX(Graphics g,Point c)
//Here, the drawLine() method does not work
g.setColor(Color.black);
g.drawLine(0-e,0-e,50-e,50-e);
g.drawLine(0-e,50-e,50-e,0-e);
repaint();
}er, unless you're using JDK 1.5 and it introduces methods I know nothing about, as far as I know
public void paintX(..) is not a AWT or Swing method. Thus it will never be invoked unless you call it. -
The forward, back, refresh, and stop buttons are not working. Even after installing the latest Firefox update. Also my home page stopped loading upon startup even tho I have it setup to do so.

[Bug?] Defer Panel Update not working when changing scale property
Hi,
I found that Defer Panel Update [when True] does not work properly when changing the scale fit property of an intensity graph.
Try the VI.
When Defer Panel Update is True, and you change the Numeric controls, the Intensity graph is not updated (as expected).
But now change the "Z Scale.Scale Fit" button and.... the Intensity graph is updated (only the Z-color, not the axis).
This looks to be a bug to me!
