VIs that allow you to test if a given control is a control of a particular LabVIEW class type

The attached zip file contains VIs are saved in LabVIEW 8.5. 
 
Included in the .zip are three VIs you may find useful when working with LabVIEW classes. 

- Qualified Name Array To Single String.vi takes a VI's qualified name, given as an array of strings, and converts it to a single colon-delimited string. This VI may be useful for working with VIs owned by any library type, and it is used as a subVI of the other two VIs in this .zip file.

- Is This Control Of This LabVIEW Class.vi takes a control refnum and a LabVIEW class refnum and tells whether the control is an instance of the given LabVIEW class. It returns true for regular class controls/indicators and for XControls of the class.

- Is This Control Of LabVIEW Object Class.vi is the same as the previous, except it does not take a class refnum for input. LabVIEW Object is the built-in class that is the ancestor of all other LabVIEW classes, and this VI specifically checks to see if the given control is an instance of this class.

The second two VIs in this .zip file are both password protected. In a built application, both will return a "not supported" error.

I'm seeing an 1063 error when I try to use the "Get Control Data Type.vi" on a control extracted from a cluster or an array. The error does not show up if I use a control reference or extract the control from the front panel. Is this a bug or am I doing something wrong?

They help me classify the controls on the Front Panel so I can pair them up and wire them to the connector pane.

How to easily control multiple controls in labview
How can I easily control multiple controls with a single write to in Labview? For instance, I need to update 50 different boolean indicators. When I update them one at a time I use a cntrl refrence in my event structure, but outside of an event structure how can I easily cycle through them and update without making 50 local variables if I need to do them all at once? Why don't you use an array of boolean indicators? Have a look at the example attached <a href="http://forums.ni.com/ni/board/message?board.id=170&amp;view=by_date_ascending&amp;message.id=204328#M204328" target="_blank">here</a>, which can also be applied to this. You should usually avoid updating the value of a control from more than one place, though (unless it's something like initialization, where you can guarantee not having race conditions). Other alternatives: using an array of booleans or using the picture control to create the image. The way i use these booleans in my UI, I had to make them separate so I could arrange them in a user friendly way. And yes this is just for initialization so they won't be getting updated in two places at once. ...

How do you control seperate motors with Labview through a remote control?

Thanks What type of motors are you trying to control?&nbsp; How do you have them/plan to have them connected to your computer?&nbsp; When you say you want to control remotely, do you mean that you don't want them connected to a computer or that you want to communicate remotely through your computer (no cables)?&nbsp; The more information you can give the better help you will receive. Cheers Hi LouidSilence, It would also be helpful to know what version of LabVIEW you are using.&nbsp; It's impressive that your starting to learn LabVIEW at such a young age, it will be challenging but worth it!&nbsp; Well first off, thanks for asking questions to my questions, it helps me too :) The kind of motors I am trying to control are IFI Robotics Multi-Speed Motor Connect to PWM or RLY port (12 volt)..

Reading controller data into LabVIEW through serial connections to controllers?
I'd like to read data from environmental chamber controllers (System Plus) into LabVIEW through RS232 connections.&nbsp; Has anyone done something similar? &nbsp;I see interfacing with the serial controllers as the biggest obstacle and although not directly related to LabVIEW programming, I'm hoping someone here can give me some advice or resources on how best to do so now days. &nbsp;My first thought is to write a program with VB or C++ to act as a terminal and write the data to a text file for LabVIEW to poll.&nbsp; Aside from using Telix decades ago to work with BBSes, my only other serial experience consists of interfacing with a Kiethly multimeter using a C++ program.&nbsp; &nbsp;I would rather not use multiple PCs but I have never worked with more than one serial port on a computer before in the past.&nbsp; Perhaps LabVIEW itself already provides for multiple serial card communications (wouldn't that be perfect)? &nbsp;Any info would be great. &nbsp;Regards, &nbsp;Dave&nbsp;&nbsp; LabVIEW has had support for serial communication for as long as I've used it and may have been part of version 1. It also supports multiple serial ports&nbsp;- built-in and USB-&gt;RS232. There are even a couple of shipping examples.

Using the cFP controller with only LabVIEW and FIELDPOINT software but no LabVIEW RT
I have a cFP-2020 controller and cPF-AI-100 modules which I intend to use in a small project. I do have LabVIEW and FIELDPOINT software but I dont have LabWIEW RT software. Is it possible to use the cPF controller with only just LabVIEW? if yes, I would like to be advised how. Thanks Dear Chuma, It is not possible to&nbsp;set up your system without Labview realtime module. There are system integrators who can build a executable for you.

Why does LabVIEW allow me to have 2 controls with same name
Here's a general LabVIEW question: Why does LabVIEW allow me to have 2 controls with the same name in the same VI?&nbsp; It seems like this only increases the chances of confusion.&nbsp; Especially when someone is just looking at a block diagram (or documentation of a block diagram). &nbsp; <img src="http://forums.ni.com/attachments/ni/170/291119/1/Trial1.JPG"> &nbsp; No other programming language that I know of allows this.&nbsp; I realize that uniqueness of name is not as critical in LabVIEW as it is in any text based language.&nbsp; For example, in a text based language, if I had 2 variables called abc and I wrote a statement abc = 12; the compiler would not know which abc was being referred to.&nbsp; In LabVIEW, if we had 2 controls called abc, the equivalent of doing an abc=12 is writing to a local variable (which is always linked to one of the controls) and there is no ambiguity.&nbsp; Still, someone looking at the code cannot figure out which abc is linked to unless he does a right click&gt;&gt;Find&gt;&gt;terminal (or a double click). &nbsp; Even though I have never and never will name 2 controls the same, I think it would be a nice constraint to see enforced by LabVIEW. &nbsp; Any input from NI engineers on this?Message Edited by S G on 12-18-2007 03:38 PM Trial1.JPG: http://forums.ni.com/attachments/ni/170/291119/1/Trial1.JPG Crazy app, but you could have a tab control with a number of...

Another possible option is to use the Instrument I/O Assistant. It is an interactive tool that generates Instrument I/O and response parsing code for you. It is very helpful in establishing a connection and helping parse instrument response data. It is pretty high level and basic, so if you want to utilize any special serial VISA functionality it may not go as deep as you would like - but it can definitely help get you started. ...

LabVIEW 8.2 control refnum type descriptor missing
In LabVIEW 7.1, the control refnum had a type descriptor property, I do not see it in LabVIEW 8.2.1?&nbsp; How do you get the type descriptor from a control refnum in LabVIEW 8.2.1? &nbsp; Respectfully, Robert cinsight wrote: In LabVIEW 7.1, the control refnum had a type descriptor property, I do not see it in LabVIEW 8.2.1?&nbsp; How do you get the type descriptor from a control refnum in LabVIEW 8.2.1? &nbsp; Respectfully, Robert You don't! The old typedescriptor has been obsoleted with LabVIEW 8.x. The reason is that the old typedescriptor was&nbsp;using 16bit lengths internally and could overrun those for very complicated typedefs. The solution was to modify it to use 32bit lengths and since that is an incompatible change to the previous format, completely hide the typedescriptor in newer LabVIEW versions.

LabVIEW 8.0 changed a constant that was wired to a Case structure to a hidden control to maintain compatibility with LabVIEW 7.1 and earlier.
Y am i getting this msg? Hi, muks, This happened because "...LabVIEW does not compile code on the block diagram that does not execute. For example, LabVIEW does not compile any code that exists within the inactive subdiagrams of the Conditional Disable structure. In addition, LabVIEW does not compile code within a Case structure that has a constant wired to it that would not execute the case with the code..."In the other words, if you have case structure, which is wired to T/F constant, then prior to version 8.x both cases will be compiled. From version 8.x the only "executed" case will be compiled. So, LabVIEW replaces constant with control for ensure that both cases will be compiled as before. refer to <a href="http://zone.ni.com/reference/en-XX/help/371361A-01/lvupgrade/labview_8_0_features/" target="_blank">this document</a> best regards,Andrey.

Finding control type from control reference
I have a stric type control (A) on the front panel of a VI. This control is a cluster made up of a number of instances of another strict typed control (B). Later control (B) is also a cluster made up of two controls, a check box and an enum. In the VI there is a value change event handler for control A. (I have included the check box to conrol B, it previously had only the enum). There is existing code in that event handler that works on the enum control. When I check a box, event handler is called and it tries to detect which enum's value has been changed. Since none has been changed, it enters into an endless loop.What I want to do is use the CtlRef (terminal?) of the event handler to execute the previous code if the control is enum, otherwise do nothing. (I'll place the code in a case structure). How can I find the controls type from CtlRef?What are those things inside the event handler called (e.g. OldVal, NewVal, CtlRef)?Thanks a lot for your time!Have a very nice weekend!

Hello All, &nbsp; I am in the middle of developing an application that will be bundled with our product.&nbsp; I have developed many such applications using visual studio, however this is my first adventure using Labview. &nbsp; As many of you know, one of the most common variables in distributing an application is the und-user screen resolution.&nbsp; With the relatively recent explosion of differing screen resolutions and aspect ratios, making applications resolution independent is even more important than ever.&nbsp; Along with this, giving the customer the ability to resize the appliction at will is a huge benefit.&nbsp; On many occasions I have walked into a customer's site to see my application shrunk down to a corner of the window, where the use can still see it, almost like an indicator. &nbsp; For visual studio, I had purchased a third party control.&nbsp; Plunk the control onto the window (it became invisible at run time) and all of the controls, fonts, etc resized as the screen was resized.&nbsp; When visual studio went to .Net, this particular control&nbsp;no longer worked.&nbsp; I had to evaluate 5 different controls&nbsp;to get one that even came close to working properly, and even then I had to work with support and beta test many versions of that control to get the bugs out.&nbsp; &nbsp; Now I know that Labview has the panel resize options, etc and I have played around with them.&nbsp; However, a...
