How to make a drawing area in order to get a trajectory​?

hello everyone
for the project that I'm working on, I need to control an XY stage.
In order to compute the trajectory of the stage, I have to make a drawing area where the operator would draw the trajectory. and then compute it and send it to the stage.
the question is:
how do I make a vector drawing area?
I thought: at each click of the mouse, the VI takes the mouse coordinate and store it. and so, I get the vectors (with a litte mathematics). and to set the speed, a text prompt opens to ask for the speed. and the VI store it in a *.txt file witch I can read with my XY stage.
big thx 2 U thanks for reading me so far. I hope you have answers or ideas for me.

Hello CHKDSK,
please open the example finder (Help/Find Examples) in Labview and search for mouse.
With the example Basic Input Demo you are able to read out the actual mouse position.
Use the right button boolean vaule to store the correct data.
Kind regards,

  • How to make Credit Control Area field mandatory in fb01, f-01, f-02, f-04

    Dear all,
    Whenever we are trying to create any accounting document for a Customer, we need to make Credit Control Area a mandatory field in transactions fb01 / f-01 / f-02 / f-04.
    This is required because we have different Credit Control Areas for different Sales Areas for a Customer.
    Can this be achieved through Customizing (making screen field mandatory) or one needs to use user exit?
    Another option could be screen variant, however, it would result in multiple t-codes e.g. zfb01 / zf-01 / zf-02 / zf-04
    I appreciate your help in this regard.
    Thanks and Best regards,
    SAP_ROI

    Hi,
    You need to write validation rule for to make Credit Control Area field  as  mandatory field for the Transaction codes FB01 / F-01 / F-02 / F-04 and please  use T. codes GGB0 & OB28 for the same.

  • How to make Delivery block at Sales Order Header level for specific materia

    Hi,
    My client want to create a delivery block EDI order at the Order Header level for specific materials
    How can we achieve this.

    Dear Varada rajan
    Go to material master, select "Sales: sales org.1" view and assign "01" against the field "DChain-spec. status" and save.  By assigning, for a particular sales area, you can block that material.
    Now go to OVSU select 01 and assign "B" against the field "Block delivery".
    Now create a sale order and post the outcome.
    thanks

    Thank you.

    In you know the Transaction and screen Variant Configurations.
    Use T-code SHD0
    Put your Sales Order t-code There : Va01
    Then Select the feilds or tabs whatever you want as mandatory , optional.
    Customize as per your requirement and save the variant.
    Next GO to the Sales Document types :
    There In the Transaction flow you will find at variant feild.
    Assign this variant there.
    Next when ever you do sales Order for that Document type the feilds will be taken in the fashion of the variant.

  • How to make Text Input in Sales Order Trigger Change Event

    Hi Gurus,
    I have a project going on where when a sales order is created, changed or cancelled, an IDoc is FTP to our freight company.
    Now the issues is when we change a sales order text input (for example, shipping note). Nothing happens. The system doesn't take this as a change so no change event is triggered.
    Text fields I'm talking about is the one from Go to --> Header. and for Item Go to --> Item.
    When I input a note in this field, it comes out in the IDoc, but when I go back to the Sales Order and change the note, it doesn't trigger a change and therefore no IDoc is generated.
    how can I go about this?
    thanks.

    Hi,
    Could you initiate the idoc creation from a workflow?
    Have you checked the event trace?
    Is the BUS2032 object type CHANGED raised? I checked our system and event is raised on text change.
    Transaction SWELS to activate and deactivate trace.
    Transaction SWEL to monitor event raised.
    Don't forget to turn trace off
    Hope this helps

  • How to make sure speakers are receiving power Toshiba Satellite L305D-S5938

    Hello, I have been troubleshooting my sound issues with my laptop and have deduced three possibilities; Speakers not receiving power, IRQ problem, or a Sound card issue.
    All sound is still being registered by the OS, I have uninstalled/reinstalled drivers, and made sure the correct output device is selected. Sound does not work on my other OS on a different partition.
    My Device Manager shows everything running correctly, and all services are running.
    Help would be appreciated.

    Sound does not work on my other OS on a different partition.
    I hope you're not offended if I suggest you check the volume-control dial on the front of the computer in the center.
    It's the most frequent cause of this sort of thing.

  • So....How do you apply for affiliation in order to get the links and support to build a site when applications are denied on sites under construction?

    Building a website , large , with old iWeb no less; not sure if i'm wasting my time. Not an expert, just have a dream. needed to ask a tech question on links to store if approved. But apparently I cannot build the site, complete with links as it will be under construction and denied approval. What does iTunes require? An up and running, possibly successfull site before approving me to re-do it with their links?

    I would suggest that you contact the Affiliate Help Desk and ask what they will need to see on your site before they can approve your application.
