Manually change ROI position

Hi...
I was trying to change the ROI position in LabVIEW .
I dont know whats wrong with the Image control.
I have made the ROI offset (x,y) position so that it can change the vertical and horizontal postion of the ROI pattern. It is changing the position but in the Image it is unable to clear the old ROI positions.

Hi saran1988
Using Vision Express VIs have there own limitations.
Setting up a manual ROI in express VI is difficult.
Why dont you use the VI attached in my first post?
All you have to do is put the code inside your producer consumer loop and add "IMAQ Clear Overlay.vi."

  • Manually Change Song Position in Playlist?

    I know that you can drag and drop songs to re-order them in the playlist, but within iTunes, is there a way to change the song's position in the playlist without drag and drop? If not in iTunes, does anyone know of a third party plugin or program that could do this?
    The question seems weird at first so I'll add a little background. I have a playlist with ~1,500 songs in it and I want to quickly change the order of newly added songs to the playlist. Adding a new song to the playlist puts it at the very bottom but I may want to put it in the middle instead and dragging and dropping multiple songs in different spots take a bit of time. Not a huge issue, but it would be cool if there was a workaround

    Many Thanks. When I tell you I tried dragging the songs around and "that" sounds fishy, just know that I had to Re-Boot twice just to get iTunes to Open today via Desktop Shortcut. Apparently, my song order attempt coincided with a rare glitch that disappeared.
    Thanks again.

  • Change in Position or Org Unit

    End user reported an issue, when user changes Org Unit or Position,  notifies Benefit.
    Benefits run the action transfer or correct payroll data. The top row should have a user name from the benefits ( since they ran action) but the last changes made shows by the user name who made changes to the Position or Org Unit.
    I tested, worked as it should be, first I made change to the position then ran action to correct payroll data, shows changes made by me.

    You got it. One user changed the position on OM side, the other user ran action on the PA side. The top row after the action has user's stamp or name who changed the position. Strange thing is that benefit is complaining that first grouuping for one EG is defaulted back that they manually changed after the first user made changes to position, and this record has user name who changed position.
    I tested, issue is not replicating.

  • How to restrict manual changing of free goods in sales order

    Hi ,
    Goodmorning ,
    We have some requirement : In sales order free goods quantity determination by system  should not be allowed to change manually , where can we do this ?
    Looking for your inputs
    Thanks and regards
    Venkat

    As per SAP Standard, when the main Item quantity is changed, the Free Goods are redetermined. In this case any manual changes to Free Goods Quantities are lost.
    But your requirement is for restricting the Chages of the Quantity of Free Goods Correct?
    I believe there is no SAP standard solution for this. You will have to apply a User Exit, which will check the Item category of each LIne item & if it is free goods (TANN) then changes are not permitted.
    Hope this helps.
    Thanks,

  • Federal court website gives a .pl document which opens as garbage until we manually change it to .pdf, is there any way to get Firefox to do this automatically?

    I am using a Mac. When downloading a document from the federal court website using Firefox, we get a .pl document which opens as garbage (in TextEdit) until we manually change it to .pdf, which causes it to open just fine (in Preview). It used to work fine, giving a .pdf document every time, but apparently upgrades to Firefox have removed this functionality. As far as I can tell my computer, an iMac running Mac system OS X 10.10.1, does not recognize the .pl format. Is there any way to get Firefox to automatically convert a downloaded file from .pl format to .pdf format? My friend tells me that Google Chrome downloads these documents with no problem. I would prefer to stick with Firefox but I might have to change if every downloaded document is in an unreadable format.
    This is a typical example of what I get when I try to open a .pl document (the pdf version is a one page document using plain English):
    =====
    %PDF-1.5
    %‚„œ”

  • How can I manually change the height of the "Type ...

    Hi all
    Just got automatically installed the latest 6.22 version of skype few minutes ago and I got a few questions. 
    First and foremost, how can I MANUALLY change the height of the textbox, where I type the messages. I would like to make it larger, like in the previous versions of skype. I don't want to move my mouse cursor through the entire monitor to reach this tiny textbox.
    And second, why you guys are trying constanly to ruin something that is working perfectly ? Going to revert to the previous version until you fix all these nuisances.
    Regards

    There is no way to do this, it is designed to be strictly landscape with keyboard, portrait without - not the best thought-out phone on the market, mainly geared towards compulsive texters and e-mailers.
    There's no way to know whetherNokia will change this with any future updates, perhaps you should make the recommendation to them directly using the 'contact us' link.

  • Is it possible to change the position of beining of text in a standard report

    Hi,
         I am wondering wether it is possible to change the position of the test (the starting point) in a standard report. I would like to print a label with different texts at different positions. If its not possible in a standard report is there any other way to do it.
    Thank you,
    Mudda.

    Hi Mudda, I don't see any way myself to set any particular starting position for your text. It looks like the best way to emulate this behavior would be to add a new line with lots of tab characters or spaces to place your new text at a specific offset from the left. You can also use Append Table to Report and wire in a 2D string array with only a few positions filled in with your various text labels as shown below. This will space text labels pretty well across the page. Try it out and see if it works for you. You could be more clever and build the 2D array programmatically if you wanted more control over position.

  • Since upgrading Iphone to iOS 5.1.1 it does not automatically use wifi internet when wifi is available. It has been draining my mobile data. I can only manually change settings with cellular data everytime I get home. Any other solutions?

    Since upgrading Iphone to iOS 5.1.1 it does not automatically divert to my wi-fi internet when wifi is available in my home. It has been draining my mobile data I  now have very high bills from my mobile carrier for high data usage. I can only manually change settings in the Network and turn cellular data on and off everytime I get home and leave the home. This is very frustrating as it wasn't a  problem until the upgrade. I have spoken to a few people that this has happened to. Has anyone found this problem and does anyone have other solutions?

    Please disregard this question. I'll submit a shorter and more direct question. Thanks.

  • Change of Position in MSS with Process and Forms

    Hi,
    I'm trying to create authorizations for a change of position in Process and Forms, but every time that I choose a new position to the employee I get the error, No authorization, with this details:
    No authorization
    Message no. 5A277
    Diagnosis
    You are not authorized to perform this activity.
    System Response
    The system cancels the activity you have tried to perform.
    Procedure
    If necessary, you can maintain missing authorizations in Customizing. Please remember that both the standard authorizations and the structural authorizations are checked.
    I have managed to change the position and create positions in SAP with t-code PPOME, but in the MSS Portal it doesn't work.
    I use authorization with context ( S_ORIGINCON ) with a FM in the structural profile that returns my objects ( O, S, P ). I also have personnel planning authorization ( PLOG ) for the returned objects.
    Any help to overcome this problem will be greatly appreciated.
    Regards,
    Diogo Silva.

    Hi there,
    We stop using SAP code to manipulate the infotype 0001, and started using our own code throw generic services I guess (Not my part of the project).
    The problem was that in a change of position for a new created position or even for an existing position there was a need for access to the default position OBJID='99999999'. That's why when you give authorization for object OTYPE=' ' and OBJID = ' ' you will not get an error, because it gives authorization for all objects, witch defeats the purpose of security.
    If you debug the functions used by the portal (MSS or ESS) you will see that in some FM on the call stack there is passed a flag that controls wether or not there is a authorization check for that default position.
    Basically ww stop using the SAP code, and started calling this FM (BAPI, etc) ourselves, and them we manipulated that flag so that we could circumvent the error.
    I hope it was clear, sorry if it was not, truth be told it was a long time since I finish that project.
    If you need anymore help just let me know.
    Regards,
    Diogo Silva.

  • Can I change the position of  change bars from left margin to right margin?

    I want to display the change bars in right page margin. If the page is odd page,The change bars position is in left page margin. If the page is even page,The change bars position is in right page margin.

    The global properties for Change bars are found in the Format > Document > Change Bars... menu option (or <esc> o b keyboard shortcut).
    The property that you need to change is Position:
    Depending upon which of the right or left margins is larger, you'll need to set this to "Side Closer to Page Edge" or "Side Farther..." to position the bars to the outside edges of the respective pages. If you have a symmetric layout, then "Closer" places on the left side (of all pages) and "Farther" places on the right.
    However, if you have multiple columns, the change bars will appear between the columns and will shift depending upon which page edge is closer, i.e. the middle columns may be left or right on any given page.

  • Manually changing a document version number when importing an existing document

    Hello.
    Like a lot of people, we are starting to make use of Sharepoint Online as part of an Office 365 subscription.
    One of the things we want to do is move a bunch of version controlled documents from their current location on a traditional network file share into a Sharepoint Document library, and then use approval and version history to control and track changes.
    At the moment these are stored with the version number as part of the file name, so we have something like "Company car policy - version 6.docx". When there's a new version, the old one is moved to an archive folder and a new copy is saved as "Version
    7.docx" which is outdated and far from ideal.
    I've created my library, tested that approvals work, and have found instructions on how to use a workflow to notify people that changes have been made. That's all fine, but if I upload an existing document into the library it will start the version number
    at 0.1 or 1.0 depending on whether I add it as a draft or final.
    What I need to be able to do is to manually change the version number to match our existing system without having someone sit there checking a document in and out. Some of them have version numbers in the 20s so this would be a huge waste of time.
    I can't believe I'm the first person to have this problem - can anyone help me please?

    You are not the only one, that is for sure!
    The only way (that I'm aware of and is easy to accomplish) to achieve this is the following:
    * Upload your history v1, v2, v3, v4, v5, v6. And then it is really in sync with your current / old version numbers.
    * just upload the new / latest file and check out/check in the file x times so the version number will increase every check in.
    I know that this sounds weird/funny time consuming. Without 3th party tooling I don't see any other solution.
    With 3th party tooling then you can perform those actions (basicaly the same actions) more quick and easy, however you need to get yourself comfortable which such tooling. One of the tools (no I'm not a sales agent or whatsover) that I know can perform metadata
    changes is ShareGate. However in PowerShell you can perform also a lot of magic and without ad doubt there are a lot of migrating tools (AvePoint, Tzunami, etc) that can also "mimick" those manual steps.
    My best suggestion is: 
    * If you need to keep the old versions upload them all one by one (if it is not too time consuming)
    Otherwise
    * create a archive for old versions and start in SharePoint with version 1 which is exactly the same as the latest non-SharePoint version and store that archive in a separate document library/folder/site. (only keep old versions if there is a reall need
    /business case or legal case to do that.)
