How to create a strictly typed control refnum using LabVIEW scripts

I want to use LabVIEW to create a strictly typed refnum control that is bound to my custom control (a defined cluster), but I'm not familiar with scripts and can't see how to do it.

If I create a new object of VI, with Refnum of control as the Style, how can I give my custom class object VI control terminal? When I try to use a reference to my control.ctl file customized (using the Open VI reference) I get an error: 'error 1057 occurred... ". Type mismatch: object cannot be cast to the specified type. »

Alternatively, if I create a new Refnum of control as above, using a standard Cluster as the object of VI class, how I can convert this refnum control to a strictly typed refnum, which is related to my custom cluster control type?

Thanks in advance for any advice,

I tried, and as usual, things were slightly different.  The big problem is that a constant control reference becomes a node, not a constant, so cannot be converted to a control.  The good news is that you simply move to the front of the new control, as you would in the dev environment.  Here is the raw code (always needs cleaning to close the refs and add save of the new control, and more, you don't need to show the FP control if you do not want).

    AHA!

    You can duplicate your original text block, put a coat of any color on the range of text you want and then create the contours of this copy. Now, the characters who are all developed in transparent traces will be in their correct positions and contours more will be your flagged - items you can delete the rest.

  • How to create a strict property node.

    I have searched for a way to create a note of strict property for an entire day and still cannot get the answer.

    I have download a Vi from the Web site of nor, but my lab computer can not open, so I open it with my lab - top and try to reproduce them in the laboratory computer.

    After that I did, when I try to run the VI, an error saying that out

    "'Stop' Boolean ': Boolean lock action is incompatible with local variables." "

    So I check the difference with the original, the only difference is that the property of the original node is a strict property type and the. When I'm doing the same thing for the double, I can't find the way.

    So, I try to look for the answer, something like this spell

    "Conversely, a refnum in strictly typed contain the data type for the object that it points to. You can change between low and strict refnums in a right-click on the refnum (or its terminal in the block diagram) and selecting "Include the Type of data" for strict and de-selection for a low typical refnum. "

    but when I right click all show icons in the schema, I have not seen any 'include data type out '.

    the image of the diagram is attached.

    Why does when I try to create the same property: value as in the image using the lab computer and the color of the 'value' will be appears to be violet so that I expected should be green for the Boolean value.

    The error you get told you that the Boolean control is set to the lock Action. You will need to change to a trigger.

    To do this, go to the Boolean control on your front, do a right-click with the mouse and select one of the Action of switching three albums from the list of the mechanical Action of the six types of actions.

    The reason is that a lock switch is cleared when read by the terminal on a block diagram, but using local Variables in your code you are reading the control of several locations. Therefore the Boolean should be set to the switch, it will keep whereby it is if after playing to ensure that all local Variables will be the correct value.

  • How to create a header for my magazine using InDesign CC

    How to create a header that will be applied automatically to all of my pages in my magazine without having to type in one by one in a text box?

    1. Always work with the character and paragraph Style. Not even a single letter should not a paragraph Style. (I do not recommend to use the default style brackets!)
    2. Create a text variable based on your title or any text that you want to appear in the header.
    3. Do a text frame on the master and insert the text variable. Take care that this block of text (such as page numbers) are outside the margin, otherwise she paint the content of the page. Put the header (and the page number) borders on its own layer above any other. Align block text in the margin, so you can then apply different page settings and use the page layout setting.

    How to create a form of type free paths (like those drawn with pencil or pen tools) using js?


    Thank you

    This is because you create separate ways. Create just a first, and then add all the pathpoints.

    Do not forget that all first path you create comes with free first 2 points, so just move these in the position as shown above. Then add the new points to the same path, rather than create new ones (lines #4, #8, and #12 in my example).

  • How to create RMA based on orders placed using api OE_ORDER_PUB

    Hello

    Can someone help me pls how to create an RMA based on the command using oe_order_pub.process_order APi.

    Thank you.

    Creating the RMA is very similar to creating a command. You must make sure that you have the correct order_type, line_type who is going to be the 'RETURN' (or 'MIXED') configuration category in the definition of transaction type.

    The API automatically create a reference on your RMA lines for command lines original, you must pass the following
    l_line_tbl (l_line_tbl. COUNTY) .return_reason_code: = 'BACK '; -Compulsory for RMA
    l_line_tbl (l_line_tbl. COUNTY) .reference_line_id: = v_ref_line_id; -Original order line_id
    l_line_tbl (l_line_tbl. COUNTY) .reference_header_id: = v_ref_header_id; -Original order header_id
    l_line_tbl (l_line_tbl. COUNTY) .return_context: = 'ORDER ';
    l_line_tbl (l_line_tbl. COUNTY) .return_attribute1: = v_ref_header_id; -Original order header_id
    l_line_tbl (l_line_tbl. COUNTY) .return_attribute2: = v_ref_line_id; -Original order line_id

    Once the RAM is created, query the order and go to the lines > tab returns. You can see the original order number and line number.
