[Resoved] How to make sure numeric entry is accepted before saving.

Running LV 2010. I have an application in which I talk to some hardware via the USB. Values are stored in the EEPROM inside the hardware. I have a screen that shows these variables as floating point numbers, and allows the user to change the variables as needed, then save to the device. The problem I have is that, if I change a number, and while the numeric field still has focus, I click the save button, the program saves the previous vaue. It's as if the value was not entered. If instead, I click off of the newly entered number in the middle of the page somewhere, then click save, it saves the new number. In the save button routine, I have tried changing the focus to the save button, then "waiting" 10mS for the display to update, then saving, but this does not work. How do I make sure the screen has accepted the change before I do the save? Thanks.

Care to enlighten us so that we can avoid making the same mistake?

How to draw a perfect circle and how to make sure it is perfectly centered inside a square

How to draw a perfect circle and how to make sure it is perfectly centered inside a square in Photoshop elements using the Ellipse option.

1. Create a square canvas.
2. With the Elipse tool, hold down Shift (Shift forces a circle). Draw the circle anywhere on the canvas (Shape 1 in this example).
3. Simplify the circle layer
4. Ctrl-click the layer to select the circle.
5. Copy the selection to the clipboard (Edit > Copy).
6. Deselect the selection.
7. Paste from the clipboard (Edit > Paste). The pasted circle (Layer 1) will be centered.
8. Delete the original circle layer.
NOTE: Step 6 is the key. This guarantees that the pasted circle will be centered.
If you want a circle completely within a square you can simply draw and simplify a circle on any shape canvas. Ctlrl-click the circle to to select it and copy to the clipboard.
Then do File > New from Clipboard. This creates the circle cropped to a square on transparent background.

How to make the manual entry of cost center in MIRO

Hi
In MIRO, Cost center field is not populating for the PO without material and with the account assignment project P. I want the cost center to be populated in the MIRO screen.
In OLMRLIST screen cost center tab is not fixed. Once the cost center populates in the MIRO i can fix it.
Please let me know the detailed procedure of how to make the manual entry of the cost center in MIRO?
Raja

Hi,
If the PO is Account assigned PO then in MIRO you need to select the Layout as Account assigned -Costcentre, the system will change the Layout of the MIRO.
So on the line item of MIRO you will find the Account assignment arrow mark (just move rightside of the MIRO line item) press this arrow mark,
then system will take to other screen where you can enter the Manual entery to the Cost centre along with G/L account in MIRO
hope this solves your problem. To enter the cost manually you need to select the Layout as Account assignment -- Cost centre.

HT200131 how to make sure only my laptop can connect to my apple tv?

I don't want to see my flatmate apple tv under "connect"
how to make sure I don't click on his tv accidentally and he won't be able to connect mine?
thank you!

Hey J-Justin,
Great question! You can name your Apple TV to differentiate it from others in the AirPlay list:
Apple TV: Change the name of your Apple TV - Apple Support
http://support.apple.com/en-us/HT200028
Furthermore, you can setup an onscreen code or password to restrict access for AirPlay. The password method sounds like the best option for your setup:
Apple TV (2nd and 3rd generation): Understanding AirPlay settings - Apple Support
http://support.apple.com/en-us/HT202618
Set a password
Go to Settings > AirPlay > Security > Password > [set password]. You can use this setting to require a password for AirPlay-enabled devices to connect using AirPlay on the Apple TV. Use this setting if your device will need permanent access and you only want to enter the password once.
Thanks,
Matt M.

MacBook Pro 15" 2007 is dead. How to make sure it's the left I/O board?

My 15" 2007 MacBook Pro is now completely dead. No light on the 85W magsafe (which does work on unibody MBP 15), battery completely empty, no sign of life whatsoever. Apple Store says I need a new "logic board" but could not specify which one, main or left I/O. How can I make sure it is the left I/O board?
The computers' power circuits have been steadily declining in recent months. It has a checkered history - it's the one that ran hot, had kernel panics due to graphics card drivers, and had the graphics card hardware issue. The computer died in October 2008 and "the logic board" was replaced under Apple Care, free of charge. When AppleCare ran out I bought a unibody MPB and my son inhereted the 2007 model, using it for his music and being pretty happy with it, until the battery would not charge anymore. He then ran it on the power supply only, until it would not boot up. Apple Store did some magic with it (probably reset SMC), it ran for a while longer without charging battery, then did the same thing (not booting, but magsafe connector showing green LED). Searching on the web I found some hints as to how to reset SMC and this worked - once. Took the computer off the magsafe when going on a holiday, when I came back it had deceased.
Apple Store quoted $ 540 for a logic board replacement. The left I/O board is available online for $ 119 and I am able to mount it myself, would do so if I could make sure that this unit has failed and not the main board. And that, friends, is my question.

Let the Apple folks - or an AASP - run diagnostics on the machine. They'll be able to tell if you need a new logic board or not. Get an estimate - if it seems outrageous then it's probably time to buy a new computer.
Just my 2¢...

How to make sure 2 Variables of same class do not share internal variables?

K, I am having trouble making a new instance of an object.
I have a class call File_Class that have a public static attribute call File_Name.
Now in another class, I have a linkedlist and each one of the element is supposely a File_Class object. The problem that I am having now is that whenever I create a new File_Class (File_Class New_Class = new File_Class (File_Name)), i am actually getting a reference to the old one so that anything that I change reflects on every element of my link list.
My question now is
1. how exactly do i enforce that a new instance of the object (File_Class) is created so i can make sure every element in my linked list is distinct.
2. why is this happening at all
thanks for your help in advance.
Hung-Hsun Su

Here is a simple example that i wrote just to demonstrate the point. it seems that i always get the same object no matter what. Thanks again.
Result:
AFTER 0 1 2

How to make sure text in landscape mode appeared in portrait?, How to make sure text in landscape mode appeared in portrait?

I think a few pictures speak a thousand words. I try to get creative and design some pages in landscape mode.
This is how the TOC looks like in landscape. As you can see there is a chapter and many pages. I didn't use sections to make sure that they don't appeared as a list in TOC page.
This is how Chapter page looks like.
But when viewed in portrait mode. nothing appeared.
How shall I make sure that at least the text in chapter page goes there?
Thanks!

If I add a text box, it does not seem that inline is an option.
When I create the chapter page, the bottom part is empty, but I do not know how to add text. If I add a text box, it is not inline.
I hope to be able to add inline text which appeared at the bottom, possible?

How to make sure an applet runs with Java 5?

Hi all,
First let me say thanks for all the help in the past. You've help me go from noob to intermediate noob. I've just about finished my first applet game which can be checked out here .
Now I've been reading about problems with mac and 1.6. (note it works on Linux). I want to make sure that it runs fine and of course I don't own a mac. So I downloaded the 5 JDK. Selected it as the java platform in Netbeans, compiled and it ran fine.
Questions:
Do I have to always use 1.5 to compile and perhaps set it as default?
Since it works in 1.5, do I compile it with 1.6 and just upload?
I'm worried I'm not testing it correctly. I mean if I have both 1.5 and 1.6 installed on my machine, how to I make sure the applet is only using 1.5 to run?
Thanks
Darrin

I haven't got a clue RE your problem other than for max-portability you should compile with [-target 1.5|http://java.sun.com/j2se/1.5.0/docs/tooldocs/solaris/javac.html].
I must say I'm impressed, except I suspect my PC must be substantially faster than any of your test platforms... can you throttle it to CPU performance somehow? Or maybe it's just that my reflexes aren't what they once where.Thanks.
There seem to be two issues. The first is what people are using. This web stats shows pretty poor penetration of 1.6.
[http://www.statowl.com/java.php|http://www.statowl.com/java.php] Penetration: 54% with JRE1.6 + 19% with JRE 1.5. Total 73%.
The second is I've read that mac and 1.6 do not get along except on a 64bit platform.
So for applets there is not much choice but to compile on 1.5 for the broadest user base. I guess the good news is 1.4 and earlier are almost non-existent.

How to make a numeric indicator not show 0 as default value

I use Labview 8.0.
I need several numeric indicators to show some calculated results, but before I get the calculation results, thoes indicator will always show "0" as their default value. So, how can I make these indicator just be blank before I get the result that I want to display?
Thanks!

You can also right click the indicator and go to data operations and than click "make current value Default"

How to make sure that Invoices went through?

I'm not sure if this is the right place to ask this question about EDI/IDocs.
I want to make sure that the invoices for a particular day were received by the customer. How can I do this at the SAP level?
I checked in WE02 and it shows me quite a few IDocs with status "07 Error during syntax check". Others are "53 Application document posted". But the customer complains that they have not been getting any invoices. Also, is there a way to see which IDoc number belongs to which Invoice number?
Please suggest.
Thanks

Hi John,
If you double click on the status 26 in IDOC (Txn. WE05), it will show you the error message with details of the error. Also you will notice that the IDOC is displayed as flat structure as opposed to a hierarchy. If IDOC is successfully sent out it will have a status record with status "03". I am not sure how you EDI subsystem is setup, but if you are sure that it has been passed to EDI subsystem then why not check in the logs on EDI subsystem whether is was processed or not.
Cheers,
Sanjeev

How to make sure all my automatic test case run in one session?

Hi guys,
I'm doing some automatic test for our products.
Now i'm hindered by an issue(maybe,due to my wrong configuration).
I've wrote some test method in a Coded UI Test project,and these run perfect on local machine.And i build an environment includes Builder Controller,Builder Agent,TestController and Test Agent etc, and that the test cases have been written
in MTM already.
After that,i built the project,deployed the project and run the Coded UI Test on Test Agent machine,and i found it seems that he test cases run on different sessions.I have no idea how to config or set up to make sure all my test cases
run just in one session.
Could anyone help me,please?

Hi dean.chen,
>>I found it seems that he test cases run on different sessions.I have no idea how to config or set up to make sure all my test cases run just in one session.
According to your description, could you please tell me what the different sessions are when you run the test cases in MTM?
Why did you want to run the test cases in one sessions?
where did you see the test cases run on different sessions?
Could you please tell me how many test agents machine you use to run these automatic test cases in MTM?
As far as I know that if you just use one test agent machine to run these automatic test cases in MTM, these test cases will be run one by one on the one test agent machine.
To help you solve this issue, please tell me more detail message about this issue.
