ThnxHi,
I won't claim to be an expert in the inner workings of the JComboBox class however from my experience, the way you would implement an undo functionality, at least the way I would do it, would be to implement an ordered collection (List or Stack or Queue, obviously not Set) to store something to remember the selection by...if the actual actual list contents can change dramatically or if the JComboBox is 'editable', then I would suggest storing objects.
Since Java stores objects as references rather than deep copying to create whole object instances, you would not have to worry about a whole ton of memory usage since only 1 copy of every object would ever be created.
Later, when the user invoked "Undo", if the object in question was the combo box, then you would just go to the last item in the list and set the selected index or value (depending on what you saved) to the value in the collection.
I don't have details or much code because I'm on my lunch break at work and don't work with java at my job, but try to come up with it on your own now and if you still can't do it, respond and I'll try to write something when I'm at home. Good Luck!

How do I undo selecting do not save password?

The first time I logged into my hotmail account Firefox asked the question - did I want Firefox to remember my password? I selected never. Now I wish to undo that selection and select remember. I went to the tools and cleared out my email address, reopened it to try to select remember. That did not work.

If you select never then you create an exception that you have to remove.
Remove the site from the exceptions: Tools > Options > Security: Passwords: Exceptions

How to undo "select distinct" in OBIEE

Hello guys
I found that pretty much in all the reports that we created in OBIEE, the presentation service would generate SQL that starts with "select distinct" when I view the query log..
I'd like to know what configuration in the Admin Tool or presentation service is controlling this behavior of OBIEE. For some reason as I am tuning the performance by running the same query in DB, the same query without "distinct" can go so much faster than the original one from OBIEE.. So I'd like to configure my RPD so that certain reports will not have "select distinct". I know that by default, the BI server will always generate a "distinct", but is there a way to override this default, if not, what might be some performance tuning tactics I can use?
Any thoughts?
Thanks

Two issues with this that I encountere:
When I selected the first suggested option at the Physical Layer for the database, I found the "DISTINCT SUPPORTED" option. There were two columns checked: Value and Default. I was able to unselect Value but not Default.
(1) What is the difference between Value and Default?
(2) If I only unselect Value will it stop Answers from adding the DISTINCT to every query created?
Second, when I selected the source from the business model mapping, it already did not have the DISTINCT box checked. Therefore, I could not limit this at the Logical layer as I would have preferred.
If you could help me understand the first option it may clarify how to implement option # 2.
Thanks...1) the defaults are stored in an .ini file and serve the purpose of defining the defaults when you hit the 'revert to default' button.
If you unselect value, you are telling OBIEE that the database for which you are changing these options does not support the distinct clause, I doubt you wish to do this across the entire application.
I think you will find that OBIEE applies the distinct :
1) when the LTS has distinct ticked.
2) When the column in question is not part of a dimension hierachy key (if it is, your telling the OBIEE server these should be unique, so wont issue the distinct)
or
3) the column forms part of a key in either logical BMM layer or as part of a physical key.
adding the column to a Dim Hierachy wont be an option in most cases, you could try playing with just setting this column as a key on the BMM layer or Physical layer , and let us know if this helps.

Photoshop CS6 - Quick Selection tool freezes Photoshop/ becomes unresponsive for minutes

After only two selections the tool becomes unresponsive for minutes.
I'm on a 2.6 Ghz retina MacBook Pro, 16 Gb RAM, and this in connection with an SSD should make this tool very good to use. Operating system: OS X 10.8 "Mountain Lion", latest update.
Unfortunately, it seems to develop some kind of overload, during which you cannot use Photoshop at all. No commands like "undo selection", "quit", "close file" are accepted.
There is no beachball, no other signs that Photoshop is working on something.
Hint: it seems to happen when you option select (subtract from an existing selection).
Hint: the freeze can be shortened by a tool switch (has to be through clicking on a tool, keyboard commands are frozen as well)
Hint: the "subtract selection" move that caused the freeze appears after Photoshop comes back to life after a couple of minutes. The subtraction to the selection seems to be random, makes no sense, and is not the regular function of the tool.
First step after this freeze would be to undo the last selection, and continue working.
If you do several "add to selection" moves, they add up in a kind of waiting line. If you do the subtract from selection move, this doesn't work, and the freeze happens.
So far, I have not noticed the freeze when adding to a selection. Adding to a selection was always quick and instant. The bug must sit in the "subtract from selection" code.
On most freezes, the ants continue walking, I just had one (again with subtracting selection) where even the ants stopped walking.
I don't think it has anything to do with Photoshop working. I have used the quick selection tool regularly under CS5 on my old machine (which was a museum piece), and while I had to wait sometimes, it was never ground to a freeze/halt like the quick selection tool under CS6.

Did this work before, or has it always been this way? Not a bug or everyone with your system would be complaining. Have not seen that.
If it has always worked that way a reset of preferences will probably not do anything.
A reset of preferences will reset to factory defaults, so you will have to reset to saved workspace.
Do you have at least 10% free disk space?

JComboBox addActionListener?

Hi, I'm trying to write a program so that when the user makes a selection from the combobox, the selection will be inputted into a string.
However, whenever I try to run the program it gives me this error:

}Thanks in advance!

Also, you have added an item listener and implemented the method from the action listener. Above all, you did not declare your class as implementing the ActionListener interface.

UNDO Tablespace Issue - URGENT

I had issues with UNDO. Here is what happened -
SQL> alter tablespace UNDO
2 add datafile '/oracle/TESTDB/data04/TESTDB_undo_04.db' size 100M autoextend on maxsize 10000M;

/oracle/TESTDB/data03/TESTDB_undo_03.dbf 7636 0
/oracle/TESTDB/data04/TESTDB_undo_04.db 100 10000
But after some time this same query gave me this error -

Multiple Selection with JCombo Box

I want to make a multiple - selection JComboBox enables the user to select many items from JComboBox and copy items from one JComboBox to another.How can I do this?

Hello,
ComboBoxModel allows only single selection. It's better to use a JList instead because it isnt worthwhile the effort to create another multi-selection model.

Undo tablespace keeps on growing

We have a 3rd party application running on our oracle(10.2.0.4) database running on 64bit solaris(sparc) machine.
Since few days my undo started going up. I increased the size from 2g to 5g. Still it is at more then 90%levels.
I ran this query to see which session is using maximum undo
SELECT a.sid, b.name, a.value
FROM v$sesstat a, v$statname b
WHERE a.statistic# = b.statistic#
AND a.statistic# = 176
ORDER BY a.value DESC
From this i found the session which is using max undo.
When i query this sid from v$session i see this is inactive
my undo retention is set to 9000 and undo management is auto
how can i check if i have expired undo blocks that are not being used

>

With an UNDO_RETENTION of 2.5 hours set, I am not surprised that you use up to (or even more than) 5g space in the UNDO tablespace! I would even call that moderate.
What is your concern? If you don't have the space for your UNDO tablespace, lower UNDO_RETENTION accordingly. Notice that UNDO_RETENTION is the wish to preserve before images for that long time even if their transaction did already commit. Why have you set it to that (relatively high) value of 2.5 hours?
Kind regards

Getting index of a string array based on user selection in a comboBox

I'm not really sure how to phrase my questions, but here goes.
I have created a string array that holds the values of a ComboBox. Based on which selection the user makes in the comboBox, I need the program to then perform particular calcualtions (based on their selection). I have tried using an ItemListener, but that doesn't seem to work. I've also tried using the ActionListener connected to the ComboBox, again...without results. I'm not sure what I'm looking for exactly, but I know what I want it to do, I'm just not finding the right way to do it. Can anyone help me figure this out?

Here is my entire code. I'm completely confused at where to put the ActionListener or how to make it do what I want. Right now I just have it set up to display a simple message in the displayArea, just so that I could see if it was working. I think once I figure out how to get the right index from the ComboBox array, then I'll be able to add the code I need to perform the calcualtions...it's just getting to that step that's not going so well! Any help is appreciated.

Problem drawing circles and ellipses

I want my program to draw an ellipse and circle. As we all know, theyre different.
I used the drawOval() method in java.awt.Graphics to do this.
Here is the crucial lines of the code:
public void paintComponent(Graphics g)
 super.paintComponent(g);
 if(currentShape!=null)
 if (currentShape.shapeType()==RECTANGLE)
 g.drawRect(currentShape.getStartingX(),currentShape.getStartingY(),currentShape.getLength(),currentShape.getWidth());
 else if (currentShape.shapeType()==ELLIPSE)
 g.drawOval(currentShape.getStartingX(),currentShape.getStartingY(),currentShape.getLength(),currentShape.getWidth());
 else if (currentShape.shapeType()==CIRCLE)
 g.drawOval(currentShape.getStartingX(),currentShape.getStartingY(),currentShape.getLength(),currentShape.getLength());
 if (shapeCount>0)
 for (int c=0;c<shapeCount;c++)
 if (myShapes[c].shapeType()==RECTANGLE)
 g.drawRect(myShapes[c].getStartingX(),myShapes[c].getStartingY(),myShapes[c].getLength(),myShapes[c].getWidth());
 else if (myShapes[c].shapeType()==ELLIPSE)
 g.drawOval(myShapes[c].getStartingX(),myShapes[c].getStartingY(),myShapes[c].getLength(),myShapes[c].getWidth());
 else if (myShapes[c].shapeType()==CIRCLE)
 g.drawOval(myShapes[c].getStartingX(),myShapes[c].getStartingY(),myShapes[c].getLength(),myShapes[c].getLength());
 }I am bemused because, it doesn't work. When I try to draw the circle, it doesn't draw a circle but an ellipse but as you can see I set the length and height parameters of the cricle to the length!
here are my other codes, see for yourself.

VBA 4198 error command fail with ActiveDocument.Save

I am getting 4198 error run time error with on the ActiveDocument.Save line below
    If optSave.Value Then                                   '
If save & close option selected...
        'Change the status of the Normal template to unchanged. If changes were
        '   made to the Normal template, the changes are not saved when you exit Word.
        NormalTemplate.Saved = True
        ' Prevent ActiveDocument from reporting that it has changed
        ActiveDocument.AttachedTemplate.Saved = True
        If frmAssemble.optCtlA_F9 Then

            Selection.Collapse Direction:=wdCollapseStart
        End If
        If ActiveDocument.Revisions.Count >= 1 Then
            'This should not happen

        End If
        ' Prevent ActiveDocument from reporting that it has changed
        ActiveDocument.AttachedTemplate.Saved = True
        ' Trap final save errors
        On Error GoTo FinalSaveError

        DisplayStatus "Save Time: " & Elapsed(DeltaStartTime, DeltaStopTime)
        'Reset Delta Start Timer
        DeltaStartTime = DeltaStopTime
    End If
The document contains embedded word documents and excel documents and works fine until enough other sections are added so that the created file is about 5 Meg. The final document should be 10 meg.   If I remove the embedded documents it works.
If I trap the 4198 code and use resume next the first save turns to a save as.   On exiting word the program will request to save multiple times.    My guess is one for every object embedded (11).   What is wrong?

Hi RN
Could you please provide the error message you're getting? There's no convenient (public) source for error numbers and messages to look it up...
If you try to save this kind of document as an end-user do you also encounter problems? Does doing that provide any additional information about what's bothering Word?
Which version of Word is involved with the problem?
Could you please be specific about what you mean by "other sections are added": What (type of content) is being added?

HELP! Need Pricing Report

I need a report with the following information:
Material, Material description, marked for deletion flag, List Price, Standard Price (cost)
Is this something that available in SAP or can I do this report using SQ01, if yes, what tables can I use?
Please help

You can create your own pricing reports with the transaction "V/LA".
The path is IMG-Sales and Distribution-Basic functions-Pricing-Maintain Pricing reports.
Step 1
Enter a short text name, consisting of two characters, the first of which must be a letter, and the title of a pricing report that you would like to create. On the next data screen you will see all key fields used in conditions, listed in alphabetical order. Select all key fields that should be taken into consideration in the pricing report.
Step 2:
If you choose Edit -> continue with AND, all condition tables are evaluated, that contain at least one of the selected key fields. If you choose Edit -> continue with AND, all condition tables are evaluated, that contain at least one of the selected key fields. In the next dialog box, mark all condition tables that are to be evaluated.
Step 3:
Choose Continue to list structure to define the screen structure for the pricing report. Make sure that on the next screen all key fields from the selected tables appear. Fields, that are not used as selection criteria when displaying the list later, can be removed by undoing selection in the Selection column. Fields can be marked as obligatory fields on the selection screen. The structure of the pricing reports means that information can be placed in different places in the list. The layout contains the following elements:
Page Header
Group Header
Item
To execute this report, use the transaction V/LD.
Path: Logistics-SD-Master Data-Information system-Conditions and Pricing-Pricing reports
Also, check the existing reports in V/LD like 28/15/17.

Gauravjit
