Dynamically set the LOV and region properties

Hello

I am building a page with 2 fields LOV, and I need help for both sides.

My questions are:
: Code to check if the region is show / hide where should I write?
: How can I change a variable binding in my SQL view object, which is used in a LOV?

Details on my page:

I have a page with 2 regions.
-Region has
... LOV projectID
-Region B
... LOV subTaskID

I added an object controller for zone A base, and now I'm stuck.

I want the page to work as:
(1) when the user navigates to the firstpage, I don't want that region A show
.... (the user must select a ProjectID)
(2) after selection projectID and by clicking on a button, then refresh the pageand B in the region shows as well.
.... (if the user can select a subTaskID)

The subtasks shown depend on the selected projectID
(I use a link WHERE TABLE.projectID = variable: 1 article)

I do not know where to put the code for "make the region visible / invisible.
And I do not know where to put the code to change this variable binding in region B LOV VO

Thanks in advance for your help

Hello

Answers to your questions:
: Code to check if the region is show / hide where should I write?
ProcessRequest of the region/Page Controller

: How can I change a variable binding in my SQL view object, which is used in a LOV?
You must have a Lov controller that would call the method in Lov AM which still add the extra whereclause or bind the value of the existing where clause.

  • How to dynamically set the height and width of the image?

    I'm trying to dynamically set the size of an image of "spacer", but this doesn't seem to work.

    "< img src ="Images/SpacerYellow.gif"width ="5"height =" < cfoutput query = "Img" > #Img.Jan # < / cfoutput > "/ >

    When I insert the source of the page and the view, it is the HTML < img src = "images/SpacerYellow.gif" width = "5" height = "745014" / > why so the stil teeny tiny image? "

    A better question would be, why are you trying to display an image of space which is more than 745 000 pixels high? The HTML code looks OK, so you may be panicking the browser.

    From the point of view best practices, if you only want to display a value in the first row of a query, you can reference using the #MyQueryName.myColumn #. You need not include the query within the tag.

  • Dynamically set the Station process model

    I noticed in an existing position, to dynamically set the active process template, you use the Engine.StationOptions.StationModelSequenceFilePath property. (Search for "How do I dynamically (at runtime) the models?").

    But where do you put the statement that sets it?

    Thank you

    Oh yes I forgot to say in my last post

    You can make a file of sequence requires a specific process template.  So that no matter what the model of the station is on the sequence of file always use the designated model provide you.

    With the sequence file that requires that the new process model open go to Edition > properties file in sequence.  Under the Advanced tab, under model Options, select require a specific model.  You will then see a box of template file.  Navigate to your new template and select it.  Click OK to exit.

    Now, whenever this sequence file is opened, it will use this process template regardless of what is the model of the station.

    Hope this helps,

  • How to add a new language to the language and region of the Panel

    Hello
    Setting preferences in Mac OS X, I could ' t help noticing the huge amount of languages available in the Mac OS X El Capitan. Located in same languages like Klingon, Navajo and Latin - and of course, this looks like a great tribute to the rich diversity of languages in humanity. However, Mac OS X El Capitan still missing a language - my own. How can I add another language to the language and region of the Panel? How Klingon and Latin is?
    Of course, I have this Internet search, but nine out of ten results were some tutorials explaining how to add an EXISTING language to the ones I already have.

    Thank you.

    Rui Valente

    You just 'Add' a language. You would have to edit all applications to create strings of replacement for all menus, dialog messages, buttons, etc., that it doesn't translate from one language to the other. Each application has a list of strings mapped to the display string for each supported language. The localized string replaces the generic string in the user interface element.

    You can try to contact Apple and volunteer to locate the operating system, they would have confidence in you (unlikely) or hire a person to validate your work.

  • How to set the position and size of the façade using the FPRunTimePosRunCustom method in a c# application?

    How to set the position and size of the façade using the FPRunTimePosRunCustom method in a c# application?

    I found a solution! -Set the size and position of the façade with the help of the

    File > VI properties > window running Position (in category list) > custom (in position of menu drop-down).

    then just accept the current position and size (leave the boxes checked) or set values you want directly (uncheck the boxes and fill in the numbers), or physically position and size the façade and use, the "set to current location" button and press "set size" current All that is easier for you.

    OK so it does not make use of the method VI Methods (Active X) FPRunTimePosRunCustom ([Position], [Size]) but if labview want to make him difficult to use then other means must be found.

  • How to outsource the JNDI name (dynamically set the JNDI name)

    Hello

    In the adapters such as ftp, database, must specify the jndi name. This binds the adapter to a particular jndi name. It's certainly better that connect the adapter directly to the physical resource, I was wondering if it is possible to have still more flexibililty-setting the jndi name dynamically.

    Basically my requirement is to develop a web service that reads a file from a FTP location. I know that I can outsource the file name and directory, but I wonder how to dynamically set the ftp location.

    http://Darwin-it.blogspot.com/2008/03/configuration-of-FTP-synchronous-get.html gives the answer if I want to set the host name, portname, user id and password.

    But I want to configure the adapter got FTP and then use this JNDI name in my service. Is this possible... I am using SOA 10.1.3.3

    According to this the below Knowledge Base article, Remote Configuration System Support must be installed on the target for time settings to change in MAX.

    http://digital.NI.com/public.nsf/allkb/FAB0EC4D6E5EE0F386257738005733A3?OpenDocument&MeTC=max_MAXDat...

    If you don't know what version of the system supported remote Configuration software that you have installed on your device target, it is likely that it is not yet installed. Add this software by clicking below your target to the MAX software option and selecting "Add/Remove Software". This is where you will install the System Configuration Remote Support software.
