Button, or other panel related question
so, if any of you have read my previous topic about painting rectangles in a panel, that worked great, but now i need to mkae those rectangles components so that when someone hovers over it or clicks on it it displays information at a certain area. I know how to make listeners and how to add buttons in a panel, BUT how do I add buttons at a specific coordinate. This program graphs data on a specific scale and therefore adding a button in the approximate area using a grid layout will not be good enough. Is there anyway for me to place the the button/component/object at the extact location that I want?
thanks in advance
In future GUI related questions should be posted in the appropriate GUI forum (likely Swing).

Backup VHD size is much more than expected and other backup related questions.
Hello,I have few windows 2008 server and i have scheduled the weekly backup (Windows Backup) which runs on saturday.
I recently noticed that the actual size of the data drive is only 30 GB but the weekly backup creates a VHD of 65 GB.This is not happening for all servers but for most of the server.Why is it so..and how can i get the correct VHD size..60 GB VHD does't make
sence for 30 GB data.
2. If any moment of time if i have to restore entire Active Directory on windows 2008 R2 then is is the process same as windows 2003..means going to DSRM mode,restoring the backup,authoritative restore or is there any difference..
3. I also noticed that if i have a backup VHD of one server (Lets Say A) and if i copy that Backup to other server (Let Say B) then windows 2008 only gives me an option to attach the VHD to server B but through backup utlity is there any way to restore the
data from the VHD,Currently i am doing copy paste from VHD to server B data drive but that is not the correct way of doing it..Is it a limitation of windows 2008?
Senior System Engineer.Hi,
If there are large number of files getting deleted on the data drive, the backup image can have large holes. You can compact the vhd image by using diskpart command to the correct VHD size.
For more detaile information, please refer to the thread below:
My Exchange backup is bigger than the used space on the Exchange drive.
https://social.technet.microsoft.com/Forums/windowsserver/en-US/3ccdcb6c-e26a-4577-ad4b-f31f9cef5dd7/my-exchange-backup-is-bigger-than-the-used-space-on-the-exchange-drive?forum=windowsbackup
For the second question, the answer is yes. If you want to restore entire Active Directory on windows 2008 R2, you need to start the domain controller in Directory Services Restore Mode to perform a nonauthoritative restore from backup.
Performing Nonauthoritative Restore of Active Directory Domain Services
http://technet.microsoft.com/en-us/library/cc816627(v=ws.10).aspx
If you want to restore a backup to server B which is created on server A, you need to copy the WindowsImageBackup folder to server B.
For more detailed information, please see:

Any value in the Rapid Charger? and other charge related questions
Ok, I think I have calmed down. I will keep my playbook. But some issues still continue to burn me. The lastest, the time to recharge off the provided wall-charger.
- So does anyone here have the Rapid charger? Does it really work faster than the wall-charger?
- WIll the playbook charge off a PC USB connection?
- Will the Playbook charge off a standard 9700 or 9800 charger?
thanks

The provided wall charger works pretty fast for me, I was actually surprised how quick.
- WIll the playbook charge off a PC USB connection?
Yes, slowly. Much slower than the provided charger.
- Will the Playbook charge off a standard 9700 or 9800 charger?
Ditto. Yes, slowly. Much slower than the provided charger.

You want to use a combination of three features, a button on the panel,
code to notice value changes using either polling in a state machine of
some sort or an event structure, and a VI Server property node to set
the Visible property of the VI being opened and closed.
The button exists on the controlling panel. The code to notice value
changes is probably on the controlling panel's diagram, and this diagram
sets the Visible property node of a VI class property node to FALSE or
TRUE to show or
hide the panel. To get the VI reference to wire to the
property node, you probably want to use the Open VI Reference node with
the VI name.

HI,
This was my final year project and im trying to tidy it up a bit so I can add it to my protfolio but im having a big problem with the following:
I have several panels all in a container, one is a button panel and one is a screen which shows an algorithm running. When you press or hover over a button in the button panel, it is displayed in the top left corner of the screen panel.
the applet is here: http://homepage.ntlworld.com/k.wood143/FinalCopy/algo.html
to get to the source just take off algo.html
the classes you want are algoApp.java, and /runjava/GrahamScan.java
any help or questions will be greatly appreciated, thanks in advancethis edited version of your code does not show the buttons in the panel. The problem was your incorrect implementation of JPanels. You should never override paint(..) but paintComponent(..) instead. your implementation would have been ok for AWT but not Swing. get rid of all of your update and paint functions. put your 'update' code in paintComponent() save the call to repaint(). The DefaultPoints Panel is unnecessary. here is a revision of GrahamScan:

I have a panel with 4 buttons. The panel is added to the main window using BorderLayout.SOUTH so that the buttons are at the bottom of the window. Now I want to align the buttons on the right side of the panel, like so:
| |
| ----- ----- ----- ----- |
| | b1| | b2| | b3| | b4| |
| ----- ----- ----- ----- |
| |
The obvious thing to do here is use
myPanel.setAlignmentX(Component.RIGHT_ALIGNMENT);
But it doesn't work. Any suggestions are greatly appreciated.
JasonAny idea why the
panel.setAlignmentX(Component.RIGHT_ALIGNMENT)
wouldn't do the trick?Because the panel is using a BorderLayout. Any inherent behavior specified by the panel would be overshadowed by the behavior specified by the BorderLayout layout manager.
By the way you also asked a component alignment question here: http://forum.java.sun.com/thread.jsp?forum=57&thread=352465

"deafult search engine on a new tab" - this thread was closed but I have a related question. [the word “default” is spelled as it on the thread] Once you put the new url in, what then? Close it? When tried, it did not work. The closest answer is noted here. Instructing to go to about:fig. Specifically, I installed the accuweather add=on and it took over my tab home page - the one that comes up when you click for a new tab. I didn't like it so I clicked the button to remove it and the page went blank. I searched to see out to restore the tab page, tired the reply at this page :

Many thanksThanks so much for your support. As I said I am not a professional, so I by chance saw a friend who is and this is what he suggested and it worked.

How can I copy a button to a panel?
I am working on this project where I have 3 buttons that need to be dragged to a panel. I have created a new TransferHanndler that can support dropping to a panel.

I want to check all functions of PCI 6534.I have read the user manual..I have some memory related questions.Please help me for that.
1.)If i am using the continuous output mode.and the size of generated data is less than 32 MB.If i want to preload the memory,what should i do?I want that first of all i load all my data to onboard memory & then i want to make start the transfer between 6534 & peripheral.Is it possible?As per me it should be.Plz tell me how should i do this?I think that in normal procedure the transfer between 6534-peripheral & outputting data from pc buffer to onboard memory works parallely.But i don't want this.Is it poss
ible?
(2).Similarly in finite input operation(pattern I/O) is it possible to preload the memory and then i read it?Because i think that the PC memory will be loaded automatically when 6534 acquires the data and then when we use DIO read vi the pc buffer data will be transferred to application buffer.If this is true,i do not want this.Is it possible?
(3) One more question is there if i am using normal operation onboard memory will be used bydefault right?Now if i want to use DMA and if i have data of 512 bytes to acquire.How will it work and how should i do it?Please tell me the sequence of operations.As per my knowledge in normal DMA operation we have 32 Bytes FIFO is there so after acquisition of 32 bytes only i can read it.How it will known to me that 32 bytes acquisition is complete?Next,If i want to acquire each byte separately using DMA interrupts what should i do?Provide me the name of sourse from which i can get details about onboard memory & DMA process of 6534 specifically
(4).In 6534 pattern Input mode,if i want to but only 10 bits of data.and i don't want to waste any data line what should i do?Hi Vishal,
I'll try to answer your questions as best I can.
1) It is definitely possible to preload data to the 32MB memory (per group) and start the acquisition after you have preloaded the memory. There are example programs on ni.com/support under Example Code for pattern generation and the 6534 that demonstrate which functions to use for this. Also, if your PC memory buffer is less than 32MB, it will automatically be loaded to the card. If you are in continuous mode however, you can choose to loop using the on-board memory or you can constantly be reading the PC memory buffer as you update it with your application environment.
2) Yes, your data will automatically be loaded into the card's onboard memory. It will however be transferred as quickly as possible to the DMA FIFO on the card and then transferred to the PC memory buffer through DMA. It is not going to wait until the whole onboard memory is filled before it transfers. It will transfer throughout the acquisition process.
3) Vishal, searching the example programs will give you many of the details of programming this type of application. I don't know you application software so I can't give you the exact functions but it is easiest to look at the examples on the net (or the shipping examples with your software). Now if you are acquiring 512 bytes of data, you will start to fill your onboard memory and at the same time, data will be sent to the DMA FIFO. When the FIFO is ready to send data to the PC memory buffer, it will (the exact algorithm is dependent on many things regarding how large the DMA packet is etc.).
4) If I understand you correctly, you want to know if you waste the other 6 bits if you only need to acquire on 10 lines. The answer to this is Yes. Although you are only acquiring 10 bits, it is acquired as a complete word (16bits) and packed and sent using DMA. You application software (NI-DAQ driver) will filter out the last 6 bits of non-data.
Hope that answers your questions. Once again, the example code on the NI site is a great place to start this type of project. Have a good day.

How to add a button on a panel's title bar?
Hi,
How can I add a button to a panel's title bar? Buttons that
are simply added to a panel's title bar become invisible.
-AltuOne way is to put your button component oustide your Panel
tag in your MXML. The set the x/y coordinates for the button so it
is on the Panel.
<mx:Panel x="20" y="168" width="250" height="118"
layout="absolute"/>
<mx:Button x="73" y="173" label="Button"/> -

Editing radio button / check box in MC question in DesignTemplates?
Anyone an idea, how can I change these radio button / check box in MC question in a DesignTemplates?
Hi there
I don't believe this aspect may be controlled by a Design Template. Probably because this is an aspect that may vary from question to question. It deals with question functionality as opposed to simple visual elements.
If you feel strongly this should be considered as part of a Design Template function, I might suggest you put it forward to Adobe.

Go button in View Panel of Query Region
Hi,
I have a search page uses Query Region, and query region includes Simple Search Panel and View Panel, I understand to get the id of the Go button in Simple Search Panel, the method is: queryBean.getGoButtonName().
How can get the id of Go button in View Panel? In dev guide, it says: pageContext.getPersonalizeGoButtonName(), but this method gives compile error.There is no this method in javadoc of pageContext.
Can you please help?
thanks
LeiTry queryBean.getPersonalizeGoButtonName()

JTable Blank Rows When INSERT/DELETE in other panel with same ViewObject
Hi,
Jdev 10.1.2
JClient
2 panels based on same ViewObject in same AM
One panel with Grid UI => JTable
Other panel with Form UI
When I insert or delete a record in the panel with Form UI and return to the panel with JTable blank rows are displayed.
The problem remains even after commiting before returning to JTable panel.
When I activate the execute button in the JTable panel, the display is OK but the currency is lost.
I suppose calling the refresh method when returning to the JTable panel should solve the problem.
Can you please suggest me a server-side/model workaround:
refresh (which option to use ??)
Thanks
Frederic
PS I tried the workaround of thread 10.1.2 JClient binding Error. but that doesn't help.Same problem with default wizard generated Master-Detail Form.
When in the detail more then 10 rows exist, the scrollbar shows that not all rows are displayed.
If I use the scrollbar to view the last rows they are blank, in order to display them I must activate the next button one time for each additional row.
The workaround is to enter -1 in the range size of the iterator.
But what if the range size is 10.
Is the blank rows display a bug?
OR
Must the scrolling area (size of JScrollPane) be defined according to the range size of the iterator?
If the latter is true:
Can somebody give me some clues on which attributes of the JScrollPane must be set (PreferredSize, MinimumSize ??) and on how to calculate this area: total width & total height if the row height for the table is set to 20?
Your help will be appreciated
Frederic
