Can someone confirm this, or tell me what the trick is.
The only way I know to do this is to put a subform on the first tab control.
Then you can put your second tab control on the subform.

...Tab control in one of the tabs of another tab control
One of my colleagues is working with a tab control. He has several tabs. He is trying to embed another tab control inside one of the tabs of the first tab control. He had placed the second tab control inside one of the tabs of the first tab control. But the problem is that the second tab control does not show up (unless one goes to the block diagram and double clicks the second tab control, only then does it shows up; when the vi is closed and reopened its again not there). I told him that I had never seen such functionality (a tab control inside another tab control) in any application but is it somehow possible. All this is required while the VI is not running and is being developed (of course it should work at run time, but this functionality must show while the VI is not running, i.e., this functionality should be non-programmatic. Is it possible. Thanks for your time.

I have been tossed into labview programming at my new job so please bear with me. I need to make a scheduler to start a sequence of events at a set date and time. I think I have a way to start it all using the ElapsedTime sub-VI, however I can't find an easy way to get the 'set start time (s)' value. Is there a front panel object that will take a user input for a date and time and convert it to seconds? All that I could find was the month calender object. My only other idea is to use a string input and parse it to a timestamp and then convert that to seconds.

If you have a timestamp control, you can click its browse button to select a specific date and time. You can then convert it to a DBL using the To DBL primitive (found in the Programming>>Numeric>>Conversion palette).
I didn't look at it carefully, but there are some other issues with your code, the one which stands out most being the ubiquitous use of the Value (Signaling) property.

...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&view=by_date_ascending&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.

If I am writing to a front panel control or reading from a front panel indicator of an FPGA VI from a host VI using the reference node, do I need to synchronize the writes/reads such that I am not writing to the control while the FPGA is reading from it or reading from the indicator while the FPGA VI is writing to it? Unless this is handled 'behind the scenes' by LabVIEW it would seem that I would have to, however I didn't see any documentation about this and it seems that a lot of the examples I have seen do not show any type of synchronization, the controls are just written to by the host and read by the target
On their own, the VIs on the host and the FPGA VI run asynchronously. You do not explicitly have to synchronize for the purposes of "avoiding a collision". You will read the most recently acquired input value, and output values from the control algorithm will be updated on the I/O cycle.
If your acquisition loop on your host is running faster than your control loop on your FPGA, synchronization will most likely not be needed. However, there are two reasons why you would need synchronization:
- If the timing of the FPGA VI is needed to control the timing of the application running on the host, or vice-versa.
- To acquire data at a known rate and transfer all data without loss to the host application for processing or d...Can classes "make" controls and indicators "appear" on the front panel.
This is what I was hoping to do. I would define a parent class called signal that was really just an interface class. All of the child classes, analog in, analog out, digital in, etc. would have to override the VI?s in the signal class. So, the first thing that the program would do is to read a text file line by line, and on each line there would be a tag telling the program which type of signal to create. Next the newly created signal would be casted up to the parent class and put into an array. Once I have my array of signals, on the front panel I would have an array of text boxes. The text boxes would be displaying the names of the signals. In a search text box, the user can type some of the characters that are in the name of a signal, and the array would reduce the list until the user finds the signal they want. Here?s what I can?t figure out. I wanted the user to click a button next to the text box, that is listing the name of the signal they wanted, and the controls for that type of signal would appear to the right of the text box. How do I make the controls appear to the right of the text box? The controls are basically an indicator for reading an analog input or several controls that allow for ramping or stepping an analog output or setting a digital output or reading a digital input, etc. I?m hoping that the class can ?make? the controls and indicators ?appear? on the front panel. Any suggestions?

What type of motors are you trying to control? How do you have them/plan to have them connected to your computer? 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)? The more information you can give the better help you will receive. Cheers
It would also be helpful to know what version of LabVIEW you are using. It's impressive that your starting to learn LabVIEW at such a young age, it will be challenging but worth it!

You have a basic misunderstanding of dataflow. Maybe you should start with some tutorials or study some of the examples that ship with LabVIEW.
- The event structure belongs inside the while loop, and not vice versa. RIght now, the event structure only runs exactly once and never again.
- If the stop is pressed first, the VI will stop. Game over.
- If the tab control is changed (from any state to any other state!), the inner loop will spin forever as fast as the CPU allows, either executing one or the other case. It just reads the tab terminal to decide which case to execute. Changing tab never triggers any events. The VI is trapped inside the event until stop is pressed to stop the VI.

I'd like to read data from environmental chamber controllers (System Plus) into LabVIEW through RS232 connections. Has anyone done something similar? 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. 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. 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. 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. Perhaps LabVIEW itself already provides for multiple serial card communications (wouldn't that be perfect)? Any info would be great. Regards, Dave
