Thx!
Acquiring through the mircophone
In previous support I was told to use port 0 to initialize the microphone port which worked on the test exe I used to sample the waveform. I did not have access to the block diagram and cannot figure out how to record from port 0. I have played around in the instrument IO dialogue but I only see settings for LPT 1, COM 1, COM2 etc. Is there an easy way to simply acquire this signal?? If anyone has a simple VI which has an example of this it would be greatly appreciated!
Re: Max Number of Labview objects
I think your are not right. When i use more then 570 objekts i got the following error message: D:\lvworm\src\mgsource\image.cpp(12443) : DAbort: bad image in ValidateImage $Id: //labview/releases/7.0/mgsource/image.cpp#1 $ The labview program crashes and is not startable again.
Re: Max Number of Labview objects
What sort of objects are you counting?
Re: Max Number of Labview objects
Now this is interesting! The main limitation in LV is the hardware as Coastal... has pointed out. That limit will always be with us. There was a limit of 550 front panel object in LV 6.1. But I understood that that limit was lifted in LV 7.0. I may have read that in the release notes, not sure. BUT... That erro you reported starts with lvworm which I believe is associated with LV 7.

Re: Data transmission
Why do you convert the sgl to an integer string and then to a U8 and then type cast that to a string which you send? All you need is to flatten it to a string (once) and if you want to keep the precision you cannot convert it to a U8. If you have an SGL and want to read that SGL across a serial link type cast the SGL to a string (just wire it to the type cast function, it defaults to a string), wire that string to the serial write...and then when you read it make sure you get all the bytes (4) and then wire that string to a type cast with an SGL as the specified type. By just type casting you are sending the data as a binary string. Unless you have some reason for adding overhead there is no need to make it a readable string.
Re: sms by the nokia
Hi I am not sure if it helps, but most of the new mobile phones have a standard RS232 serial port. It means that you can talke to your phone and send a command to send SMS using VISA serial vis. good luck Pawel
Re: Internet toolkit problem - growing Active Connections list
OK, I found it. The main part of top vi must be enclosed in a while loop as it is done in all Internet Toolkit examples. Then the problem is gone. I guess it is connected with the way how G web server talkes to the CGI read request.vi. Pawel
accessing front panel LEDs in several subVIs
Hi, I'm new to LabVIEW! Ok, what I'm trying to do is create a front panel with 9 LEDs. Then I have a Menu Ring, with three different options. These options determine the order in which the LEDs are lit. So what I was planning on doing was creating three subVIs, one for each of the options...but how can I do that when I only have one boolean for each LED? So basically how can I relate the LEDs on the front panel into the subVIs? I tried using globals - but it seemed like that just passed on the state of the boolean instead of allowing me to actually change the boolean in the subVI. I hope this makes sense...I'm really confused! Thanks for any help!
Access Autonumber property using LabVIEW 6.1
I am having problems generating an autonumber in MS Acess for test records. I am using LabVIEW 6.1 with the database connectivity toolset. If anyone has an example, it would be appreciated.
LOGGING RATE IN LABVIEW 7.0
is there an easy way to set a a different logging rate than the scan rate when moving data from DAQ assistant VI to Write Labview Measr. File VI.
Re: I would like to attain sample Labview Developers exams.
There is not a sample test, but you can download a pdf of the Tasks and Objectives that might covered on the test a href=http://volt.ni.com/niwc/common.jsp?page=custed_cecp;here/a. Look for the Certified LabVIEW Developer heading, then click the Tasks and Objectives link. There is also other information available on that page. I didn't take the prep course, but a co-worker did and he did pass the test after taking it. Ed

You can put the terminals for the Booleans in the different diagrams and about the only other thing to keep in mind is that you probably want a delay in the loop. Greg McKaskle
Re: sms by the nokia
Hello, This posts reminded me of some project I did in the past for our microscope where I send out notifications to users after it has finished scanning on my custom made LabVIEW program. First, you have to select a phone which has data cable (a COMx port connectivity)earliest is a 5110 followed by 6110, 6150) the rest uses an IrDA and a modem driver. Each of these phones has AT-Commands set (you can download from ETSI) depending again on the series. Ordinarily you have to send out a AT+ Command using VISA or earlier Serial Port VIs or Library and arrange the bytes so that they follow the exact AT commands.This is a tip you could begin with.
