    Welcome!

    You will definitely find a lot of useful information here just by searching through the existing forum archives. As you'll find, there are many LabVIEW enthusiasts that hang out here that are more than willing to let you pick their brain ;)

    I can't read French, but this looks like a good first attempt. There are some things that pop out at me:

    1) The front panel is a little skewed. If you are going to have anything resizing with the panel, then you may want to have everything resize. I personally like to not have anything resize, and not show the scroll bars so that the FP is fixed...but that's a preference thing.

    2) The BD is for the most part fairly clean. Good job! Even though I can't read the labels, I can understand the flow and logic behind the code.

    3) You may wish to take the main code and place it into a subVI, with your parameters as inputs and waveform/results as outputs. This will clean it up a bit more.

    4) Are you sure on your math to get X in radians for the input of the Sine function? I'm seeing (Phase/(360*Freq))*(Freq*2pi) for the first iteration of the loop. It's early yet in Seattle, so I may just need a second cup of coffee before I understand what you're doing here... :)

    5) Alright, I need to know... what does this mean in English?

    My wife's name is very close to this: Carrie Sines... so I'm dying to know :)

    >>The scan list is invalid<<.

    Has anyone a idea what I´m doing wrong?

    It looks like you may not be formatting the channel list correctly. I believe that the AI sample VI that comes with AdLink takes a comma separated (no spaces) list of channels as a string input... like 0,1,2,3

    It would help to post the code that you are having trouble with here. I'm just guessing at this point ;)

    Your problem isn't clear by this explanation... please provide more detail?

    i want to print out the "waveform chart". can i do it
    just push the button. ( example; stop button is stop the program etc..)

    Check out this example (found by searching the examples in the help section for "printing"):

    <LabVIEW>\examples\reports\PrintControlExample.vi

    Here is a simplified example that may be more clear on what is going on:

    There are other ways to do this, but this is probably the easiest way.

    You can also try looking on eBay, but if you just want to look at the source code, you can download a fully functional evaluation version from NI's site which works for 30 days. I believe that if you look around their FTP server you should find versions going as far back as 7.0, but you might find only the latest.

    Really? I haven't been able to find a copy of 7.1 to save my life... does anyone have a link to an activatable copy? Our copy seems to have vanished and our rep is having a hard time finding one.

    Here are some examples of different ways of taking multiple data types and writing to a text file. Notice that the write to text file VI can take a single string, or an array of strings (which it writes each element to the file as a line).

    Look into the help of the VIs that I've used to find out more. There are a lot of different ways to accomplish this, as you can see:

    For boolean events, I have much better luck using the "NewVal" event input value vs. the actual terminal, because the value of the terminal inside the case structure can get confusing depending on the mechanical action of the switch. The NewVal value will be whatever the control's value was when the event fired (when it's value changed), and doesn't depend on when the button latches. This code worked more consistently for me:

    Also, I noticed an oddity in the code here... will this ever be false? :)

  22. What's the minimum screen size you can stand?

    It's a VGN-SZ360P, which actually has a 7"x11.25" screen (hey, I was close) which they call a 13.3" widescreen.

    The full dimensions are 3.7lbs, 12.5"x1.3"x9.3" (WxHxL). I would definitely buy it again for a travel laptop. For such a small package, they packed a lot into it.

    One problem I had with a VGN-S18GP model was that it could not recognise PCMCIA E series card: 6036E.

    This gave me endless grief over installing drivers.

    Anyone else anyone else had this problem with any VAIOs?

    Haven't used PCMCIA cards for a while now, so can't give you any feedback for my VAIO. I'm all about USB DAQ nowadays ;)

  23. What's the minimum screen size you can stand?

    I do a lot of work during the commute between Seattle and Port Orchard, WA (about 1 1/2 hours to kill each way and most of it is on a ferry).

    I have a personal laptop that I've had for 2 years (HP widescreen 17") that I bought for the screen size. Loved it back then, but recently I was given a work laptop that is a 8"x12" (or so) widescreen VAIO. It weighs half as much as my HP, and lasts twice as long. Screen is much, much sharper as well.

    Bottom line: My HP is sitting at home under a pile of books, my eyes are not as strained, and my shoulder doesn't hurt anymore...

    I've taken both on planes, and had similar experiences as the others here. That HP was basically pinned up against my gut and the screen was tilted at an awkward angle toward me. Gave up taking out the laptop on flights eventually, but with the VAIO I'm perfectly fine...even in business class :)

  25. Problems with serial Baud rate

    I think MAX defaults to the windows default settings.

    I agree with shoneill on the MAX issue. After you change the Windows port settings from within the Windows device manager you should see MAX default to the new changes. I also agree that it is good practice to rely on the code, not MAX for proper configuration of your serial port.
