Led should stays on after the object containing the qr code is scanned

Hello everyone
i am working on a project where i have to do sorting of Object using QR code. ( the sorting mechanism is done using motor)..
I am doing step by step.. I already interface the labview with arduino using lifa.
Now in my VI, when i press the boolean, the webcam is on, the camera decode the qr code using the vision assistant.
then if the qr code is matched with the qr code i want to be sorted, the motor will on..
Now i try to use LED first to understand the concept n work with simple thing..
in my VI, when i press the QR code n it is matched. i represent the motor with a led which i put it at pin 3 as shown in the attachment...
But my main problem is that when i scan the qr code, the led is blinking . I dont want it to blink. I want it to stay on ..
can some1 help me with this please.
i try many possibilities. i try with case structure, with while loop..
but the led continues to blink.

The object contains an unrecognized argument: "JobId"

Hi all,
I'm trying to push configuration on two nodes using WMF 5.0 Preview February 2015 but it is failing to create job on one the second node. Would appreciate any advise on how to resolve this issue.
Command:
Start-DscConfiguration -Path C:\MOF\AzurePackAdmin -Verbose -Wait -Force
Error:
The WinRM client cannot process the request. The object contains an unrecognized argument: "JobId". Verify that the spelling of the argument name is correct.
+ CategoryInfo : MetadataError: (root/Microsoft/...gurationManager:String) [], CimException
+ FullyQualifiedErrorId : HRESULT 0x803381e1
+ PSComputerName : node02.domain.lab

Try and delete the content of the c:\MOF\AzurePackAdmin folder, generate the MOFs again and try to apply the configuration. If that is unsuccessfull, reboot the nodes if you have not tried that. If the error persist, create a dummy configuration like this:
configuration Telnet
Param(
[String[]]$Computername
Foreach ($computer in $computername)
Node "$computer"
WindowsFeature TelnetClient
Ensure = "Absent"
Name = "Telnet-client"
Try and apply that configuration to the nodes. If the configuration gets applied, then there is most likely an error in WMF5, the DSC resource/module or the configuration.

Cs5.5 trial: "please insert the cd containing the trial"?

Hello,
I am having difficulty installing the master collection cs5.5 trial. After selecting wanted applications the installing-bar stops and wants me to insert the cd containing the trial. Why do I get this message?
Regards
Mikael

And on what system? What applications do you choose specifically? Is there any previous Adobe software on the system? The installer wanting a CD/ DVD could mean anything from you having chosen to include extra content that is not part of the trial to some install infor from previous versions being sticky and messing up things...

How to select the objects sharing the same appearance in the same artboard?

I have several artboards in the file and I want to select all the objects having the drop shadow effect in the artboards I'm working. No matter I use the "Select" in the menu or the "Select similar objects" button in the control panel, it selects all the objects having the same appearance in the entire canvas, not only the one in the artboard I'm working. Any means or there's nothing can do?
Please help!

J_Lai wrote:
yes, that's work and I also tried to lock the objects in another artboard in order to select the objects in the working artboard only. However, I think that's stupid to get it done in this way and Adobe should improve this in the next version.
This is easy enough to state but if you think this is wrong then you should perhaps suggest a way this feature could be manifested.
For instance to you this should only effect the current artboard but there will come along another user who will say hey wait a minute I need to select all the drop shadowed objects and remove them now I have to go from atboard to artboard.
If you see what I mean, II found out that when I find something that is seemingly stupid that in fact there is a reason for it and there has to be a way to describe how it can be improved without breaking what you already have.
For instance you want it to just effect the current artboard but then there will be those who also want it if it even touches the artboard and those who will want it on a range of atboards and those who will actually want AI to know which artboards you want even without you specifying which artboards. That last one sounds illogical but that is the nature of the problem and the human conditions.
So though I agree this can be improved perhaps you have an idea how this can work for everyone?

How to determine the object in the tablespace

Hi
I have a problem with my database, How can i determine the object in the tablespace
and how do move old tablespace into new tablespace and how to drop existing tablespace.
Thanks

Hi,
If you want to find for all objects information, you can use dba_segments and filter this against the tablespace name. Once done you can create another tablespace and move the objects from old tablespace to new tablespace. Later you can drop the old tablepspace. You can use the below mention commands also:
SELECT 'ALTER TABLE '|| table_name ||' MOVE TABLESPACE USERS;'
FROM user_tables WHERE tablespace_name='MY_TableSpace';
SELECT 'ALTER INDEX '|| index_name ||' REBUILD TABLESPACE USERS;'
FROM user_indexes WHERE tablespace_name='MY_TableSpace';
SELECT 'ALTER TABLE '|| table_name ||' MOVE LOB ('
|| column_name ||') STORE AS (TABLESPACE USERS);'
FROM user_lobs WHERE tablespace_name='MY_TableSpace';
On the other hand,
You can also export a backup of the source tablespace and import into the target tablespace.

I'm having troubles converting my raw files from Nikon D5200 (NEF) to DNG. I tried using Lightroom 4, but it didn't identify the folder containing the files. So i downloaded the latest DNG converter but that too didn't identify the files kept in the folde

I'm having troubles converting my raw files from Nikon D5200 (NEF) to DNG. I tried using Lightroom 4, but it didn't identify the folder containing the files. So i downloaded the latest DNG converter but that too didn't identify the files kept in the folder location. So I downloaded DNG converter v7.3 for D5200. It identifies the folder and files; but it is giving me parsing error on trying to convert files. I'm running Windows Vista Home Edition SP1. Kindly advise. Thank you.

I probably missed this detail in what you’ve posted, but do you see the thumbnails of the three cameras’ raw files in Finder if you don’t convert to DNG?
What has happened in the past is that the Apple raw interpreter doesn’t read thumbnails of DNGs it doesn’t like, where at least one thing it didn’t used to like was embedded lens corrections for mirrorless cameras. Are the Olympus and Panasonic mirrorless—meaning there is no optical viewfinder and everything is seen on an LCD screen or perhaps an electronic view finder? If so the reason these are different is that the camera is doing the lens distortion corrections automatically and this information is stored in the raw files and in the DNGs but Apple doesn’t know how to use these embedded lens corrections or doesn’t know how to read the newer DNG spec that does allow for this information to be embedded in the DNG, at least.
Apple could just extract the embedded jpg preview and ignore the other parts of the file it doesn’t understand, but it apparently doesn’t do this.
What I’m not sure about is if the Apple raw interpreter still has this problem or if you’re on an older system without the latest updates for camera raw decoding by Apple.

Cannot remove the access control entry object on the object because the ACE isn't present

Hello,
I am very new to using Powershell and Exchange Management Shell, and have no prior experience using either of these tools. However, the software I am installing requires me to use the EMS tool in order to set certain permissions for a user in Exchange, which
will be like the admin account.
The command I am attempting to run follows as:
Get-ExchangeServer | Remove-ADPermission -User $newusername -Deny -ExtendedRights Receive-As -Confirm:$False
This throws me an error saying:
cannot remove the access control entry on the object because the ACE isn't present. I've done some research, and have found that this error is quite common, but the solutions do not apply to what I am specifically trying to accomplish. I am simply trying
to remove the Receive-As permission for the admin user that I just created.
Once again, I am very new to Exchange and Powershell, but if there is any advice anyone has, it would greatly appreciated.

I ran this command, and a very long list was displayed, it looks like everything is there.
The weird thing is that I was able to run a previous command which granted Receive-As access to the user I am creating:
Get-ExchangeServer | Add-ADPermission -User $newusername -accessrights GenericRead, GenericWrite -extendedrights Send-As, Receive-As, ms-Exch-Store-Admin -Confirm:$False
The description for the commands to run read to 'grant permissions and to revoke denies, if present'. I'm not sure what this means, but the second part of this pertains to the second command that I am having trouble with:
Get-ExchangeServer | Remove-ADPermission -User $newusername -Deny -ExtendedRights Receive-As -Confirm:$False

While listening to a podcast on my iPhone I can e-mail the podcast ID. The email contains the url for the specific podcast. So you would assume that you could put that url into iTunes and it would take you to the podcast. This used to work but no longer.

While listening to a podcast on my iPhone I can e-mail the podcast ID to share it with someone else. The email contains the url for the specific podcast. So you would assume that you could put that url into iTunes and it would take you to the podcast. This used to work but no longer. Months ago when I would e-mail myself the url all I had to do was click on the link in the e-mail and it took me right to the specific podcast in iTunes. Now it only opens iTunes and I can't figure out how to find the specific one. What good is the e-mail tab on the iPhone if it doesn't connect you to the podcast you sent?

Same here. I just posted a question too.

Copy all the objects from the one system that start with (ZANK)

hi to all,
I have installed the name space /ank/ in the US system, we need to copy all the objects from the India system that start with (Zank) and re-create them as /ank/. problem is how can i copy objects and re-create.
thanks

Hi Ankal,
I guess this is your second thread on the same question. Ok provide these information
>>I have installed the name space /ank/ in the US system,
Are you saying that you have a machine (US System) and i has a namespace /ank/ ? What all objects are there in this namespace?
>>we need to copy all the objects from the India system that start with (Zank) and re-create them as /ank/.
Is the India system on the same US system?
Also tell me whether you have opened the home page of SAP XI/PI? If yes , are you able to open Integration Repository? If yes then how these US and India systems are referred in Integration Repository? Are they referred as separate software components?

Can't scale the objects. The requested transformation would make some objects too small to use.

How does one remedy this Adobe error message? "Can't scale the objects. The requested transformation would make some objects too small to use." This one always gets me. I'll spend more time trying to find the object in question. This has happened in almost al versions, but this time it's CS5.

Hmm, possible solution would be to select your object(s), scale them to 90%, and then hit Cmd+D or Control+D to repeat the transformation. I read that sometimes if you scale down too much and too fast it can cause this message.
Hope this works for you!

How do you create additional free space on the volume containing the iPhoto library? I have plenty of HD space.

How do you create additional free space on the volume containing the iPhoto library? When attempting to import images from a CD I get an "Insufficient Disk Space" message albeit there is plaenty of additional space on the hard drive.

How much free space do you have on your hard drive? Try the following:
1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your
User/Home/Library/ Preferences folder.
2 - delete iPhoto's cache file, Cache.db, that is located in your
User/Home/Library/Caches/com.apple.iPhoto folder (Snow Leopard and Earlier).
or with Mt. Lion from the User/Library/Containers/com.apple.iPhoto/
Data/Library/Caches/com.apple.iPhoto folder
3 - launch iPhoto and try again.
NOTE: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding down the Option key when launching iPhoto. You'll also have to reset the iPhoto's various preferences.
NOTE 2: In Lion and Mountain Lion the Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and hit the Enter button - 10.7: Un-hide the User Library folder.

Download the Windows Installer CleanUp utility from the following page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
http://majorgeeks.com/download.php?det=4459
To install the utility, doubleclick the msicuu2.exe file you downloaded.
Now run the utility ("Start > All Programs > Windows Install Clean Up"). In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove", as per the following screenshot:
Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time?

I am trying to copy a document and I keep getting the error "Can't paste the objects. The requested transformation would make some objects fall completely off the drawing area."

I am trying to make duplicate documents with minor adjustments to each and when I try to copy the artwork from one document and paste it into the new document I keep getting the error "Can't paste the objects. The requested transformation would make some objects fall completely off the drawing area." Both documents are exactly the same size, res, color format etc. I even tried to drag and drop and get the same error message. Anyone know what I can do to resolve this issue?

Try scaling the view size down to 6% or so and then do a Select All. See if there are objects off the artboard which may be causing this error. Most often you will see this if there were guides dragged from a ruler which were selected by dragging the white arrow and then deleted. This leaves the anchor points at the edge of the work area.

1) Is there a function to make all the object to the same size?

1) Is there a function to make all the object to the same size?
Solved!
Go to Solution.

Sorry, I thought you wanted to align the objects.
We don't have the function to make objects to same size. You have to edit them one by one. To edit the .lks file can be more efficient.

The Object Container

I want display a Label on the Container. the Value of Labl ist changed
I post some code
class A{
Container contentPane=this.getContentPane();
new B().addInfo(1,contentPane);
public class B
public void addInfo(int count,Container container)
JLabel L= new JLabel();
L.setText("number: "+count);
container.add("South",L);
the method addInfo(...) will be called sereval times and evrytime the label become an new value.
the problem the Value of label is changed but can not be displayed
Why ???
thanks for help

The documentation for container's method public Component add(String name, Component comp) says:
"This method is obsolete as of 1.1. Please use the method add(Component, Object) instead. "
Try switching your call container.add("South",L); to container.add (L);I am not sure what you intend "South" to do but if you are trying to add it to the bottom of a Borderlayout then you should use BorderLayout.SOUTH instead. But that will not work as desired if your method addInfo will be called multiple times. On the second and subsequent call the component that is in the south possition will be replaced.
