First, if you want to start getting beyond the basics with DAQ, you are going to have to stop using the DAQ assistant and do it with lower level DAQmx VI's.  There are hundreds of examples in the example finder.  You can even right click on the DAQ assistant and select open front panel.  That will create a subVI that you can open and see what is going on behind the scenes.  Do it.  I think you'll find the DAQ task is being recreated on each (though I'm not 100% of how the settings are established or maintained in each section of that subVI).
The second problem is you have a bit of a race condition on iteration 0.  Those two DAQ property nodes are running at the same time.  So when you read the AI.Max, it may be happening before or after the AI.Max is set in your case structure.
Third, make sure you wire up your error wires.

  • How can I apply a current fill color to a stroke, then adjust that stroke color's build?

    Hi all, I'm trying to figure out a way to automate a simple, yet repetative process I do countless times a day. Ideally, I'd like to tie it to a keystroke to speed up my workflow.
    I work on line art and colorways for footwear, so the way I'm coloring these shapes and strokes helps to break apart the different materials and pieces of the shoe.
    While coloring line art, I work with Pantone spot colors as fills for closed path objects. I then have to manually apply that same color to the stroke, set the stroke to 0.5px weight, convert that spot stroke color to CMYK, and add 15% to the K value.
    I found some code in an older post for applying the actively selected object's fill color to the stroke, but I'm having but I'm having trouble with the next step of figuring out how to take that spot stroke color and convert it to a CMYK build that I can then add 15% black to. Is this something that's even possible? I've spent about an hour playing with the script and have only had luck matching the fill color or turning the stroke white. Thanks for the help!

    ok try this one, I added the spot color option
    // make stroke color same as fill color + 15% black increase
    if ( app.documents.length > 0 && app.activeDocument.pathItems.length > 0) {
        for (var a=0; a<app.selection.length; a++) {
            try {
                    var sel = app.selection[a];
                    var fillcolor = sel.fillColor;
                    if (fillcolor.typename == "CMYKColor")
                        var cmkycolor = fillcolor;
                    else if (fillcolor.typename == "SpotColor")
                        var cmkycolor = fillcolor.spot.color;
                    var col = new CMYKColor;
                    col.cyan = cmkycolor.cyan;
                    col.magenta = cmkycolor.magenta;
                    col.yellow = cmkycolor.yellow;
                    var black = cmkycolor.black + cmkycolor.black +15;
                    col.black = black>100 ? 100 : black;
                    sel.strokeColor = col;
                    sel.strokeWidth = 0.5;

  • How can I programmatically change a label?

    Hi everyone,
    I have a 2-D array that I wish to populate with different sorts of data.  Depending upon the data, the names of the rows and columns may change.  Arrays have to have identical labels and I suppose I could simply populate a string indicator, but frankly, that looks like trash.
    How can I programmatically change a label of a column or a row in a 2-D array?  Should I consider using a table?  I want it to look nice.
    Thanks,
    Jason

    Hi
    I do not think you are able to change the label programatically.
    But you might consider to use Captions instead of labels. You can hide labels and make captions visible programatically, and you can change the text of the caption and size (see enclosed vi).
    take care

  • How can I permanently change a text color in Terminal.app?

    According to Terminal's help file:
    "To change the color of the Terminal window or text, drag a color from the Colors window to the Terminal window. If you drop the color on an empty part of the window, the window background changes to the color. If you drop it on text, the text changes to the new color."
    This works like a charm; I drag a lighter blue color onto the dark blue that some distributions of linux display by default when showing a directory in ls and the color changes for the rest of my terminal session in any ls.
    The question is how do I make this change permanent? I tried saving my terminal session into a .term file and opening it, but this change wasn't saved. Everything else was, of course, but not this one.
    Any ideas how to make this sort of change permanent?

    Sorry, but that doesn't address the actual question. I probably was unclear when I asked, so it's my own fault.
    I am not trying to change the color of the cursor, normal text, bold text, or selection. I am attempting to change which color blue shows up when an ansi code for blue is displayed. This can be done by opening the Show Colors interface from the Font menu then dragging the new color to the existing one (so if I have text displayed in Blue that reads "foobar" and I drag aqua onto that text, all Blue text now appears aqua in that Terminal session). The question is how do I make this change permanent?

  • How can I programmatically change the colour of tab pages? If not, when?

    I have found that in LabVIEW 6.0.2 the "Dialog" tab control cannot be coloured, but the other type of tab control one can be coloured by the paintbrush tool. I cannot find any property node to programmtically set the colour of the enitre tab control or individual pages. When will these properties be available in LabVIEW?

    The dialog controls and indicators are designed
    specifically for use in dialog boxes. These controls inherit their color from the colors you set in Control Panel >> Display. Because of this you will not be able to programmatically change their color.

  • How can I programmatically change the voltage range settings in a DAQ Assistant

    Hi,
    First post here.  
    I need to be able to change the voltage range properties of a daqmx DAQ Assistant based on user input.  My hardware, an SCXI-1102C does not allow changing this property on a running task, so I'd like to either set the analog input voltage range before the DAQ Assistant activates, or pause the DAQ Assistant immediately after it starts, set the values and then resume.
    I don't know how to edit the task ahead of time because the DAQ assistant creates the task when it runs, and there is no task before that.
    In the attached picture, I have a conditional section, set to run only if the while loop iteration is 0.  I take the task from the Daq assistant, send it to a stop task vi, set the property, and then send the task on to the start task vi. I can watch it run with the debug light on, and everything seems to work correctly, but on the second (and all the other) iteration of the loop, I read out AI.Max and it seems like the DAQ Assistant has re set it back to 5V.  Can anyone see what is going wrong here?
    BTW, this is continuous acquisition and the code does not produce error messages when it runs.
    I did come across a similar question that someone posted here back in 2006, but his question was specifically aimed at a Labview API (VB, I think), and not an actual G solution.
    Attached are the actual vi in question and a png image of the block diagram.
    Thanks!

  • How can I get scripting access to color values in the indexed Color Table?

    Hey all,
    I'm relatively new to Photoshop scripting, but I've just finished a script that helps my fiance with some very tedious tasks related to textile design.
    The last issue that I'm having is that the image I start with is indexed and has a very specific Color Table pallete ( 2-12 colors max + black and white, so 14 max total, sometimes as few as 2 ). Part of my script, I create a number of color chips and fill them with black currently... What I'd like is to be able to get a count of the colors in the Color Table and put the actual color values as hex into an 1 dimension array, so that I fill those black chips I've made with the actual colors from the Color Table.
    ( I don't know if it makes a difference but I'm converting the image to RGB mode at some point in the script, and back to Indexed Exact ).
    Can anyone please help me do this? Needs to be compatible with CS5 and CS6 ideally.
    Thanks!!

    Cheers for that, your code works but what had thrown me was that the collections appear to be empty - so I hadn't actually tried retrieving one, I just assumed I was looking in the wrong place.
    So if I do this in my Immediate window:
     App.Current.Resources.Count
     0
    Yet when I request it, I get one:
     App.Current.Resources["TitleTextStyle"]
     {Windows.UI.Xaml.Style}
         base {Windows.UI.Xaml.DependencyObject}: {Windows.UI.Xaml.Style}
         BasedOn: {Windows.UI.Xaml.Style}
         IsSealed: false
         Setters: {Windows.UI.Xaml.SetterBaseCollection}
         TargetType: {Name = "TextBlock" FullName = "Windows.UI.Xaml.Controls.TextBlock"}
    Looking at the resources object itself, I get similar apparently empty collections:
     App.Current.Resources
     {Windows.UI.Xaml.ResourceDictionary}
         base {Windows.UI.Xaml.DependencyObject}: {Windows.UI.Xaml.ResourceDictionary}
         Count: 0
         IsReadOnly: false
         Keys: Count = 0
         MergedDictionaries: {Windows.UI.Xaml.DependencyObject}
         Source: null
         ThemeDictionaries: {Windows.UI.Xaml.ResourceDictionary}
         Values: Count = 0

  • How can I manually change contrast/brightness/colors?

    I want to simply use some slider to adjust the contrast, brightness, gamma or color balance in my MacBook Pro, but for some reason I'm unable to find it. All I can find is the calibration process, but when I calibrate it "correctly", the screen is a bit too dark so I just want to adjust the brightness/gamma manually AFTER the calibration. How? Where? Please don't tell me that it's one of the "Apple doesn't allow me to do this" things ;-)

    VarHyid,
    The only way I know how is though System Preferences > Displays
    For Brightness there is a slider in System Preferences > Displays > Display ( Tab )
    For Gamma and Contrast you have to use the Display Calibrator Assistant found in System Preferences > Displays > Color ( Tab ) > Calibrate...
    Although if you use Expert Mode there are more options.
    You can fine tune the Color Profile settings if you use Expert Mode. Then you just go through the prompts and adjust as you would like it.
    Hope that helps,
    Weston

  • How can I reset my imac to factory settings without the ilife cd?

    I have an iMac that I bought in 2006. I recently purchased a macbook pro for college, so I thought it would be nice to give my old iMac to some family friends. However, I don't want them to have all of my information that's still on the computer. I have already backed up all of the files that I need, so I'm prepared to erase the hard drive. I've been reading online that you need certain things to do so: startup dvds and ilife dvd/cd/whatever. I have the first, but not the second. Is there a way to erase the HD without the ilife? Can I use a newer ilife dvd? Or is there an easier way to do all of this??

    Hi Jacob: There is no requirement of the iLife DVD to wipe the computer. If you have the original install DVD, that is all you need.

  • Fill color is outside the path

    One of the graphic elements I was given has me stumped.  When I select it, I can see the path of the object and see that it has a fill color and no stroke.  However, the fill color extends outside the path. This ends up causing me a headache when I try to slice and save for web.  I can never get the result I want in a PNG.  I always end up with a few pixels more or less wrong on one or more sides.  Help!

    pcdavis,
    You may have Effect>Offset Path applied; you may see it in the Appearance palette/panel, and click the Reduce to Basic Appearance button there.

  • How do I change the stroke color while retaining the fill color using eye dropper in Illustrator?

    I have a question regarding illustrator.
    Let's say I have a circle with blue fill and red stroke. And I place an image in the illustrator file. Now I want to change the red stroke of my circle to let's say a purple color by sampling the color from the image.
    How can I achieve that with a eye dropper tool? Every time when I try to sample a color from the image, the whole circle will change to purple instead of just the stroke?
    I have tried multiple key combination, shift, alt, ctrl but they all don't work.
    Cheers, Venn.

    What you were saying is essentially what Mike's screenshot is all about?
    Deselect Focal Fill on Picks Up and Applies.
    I don't see how disabling them will help?
    If you have an image, Illustrator reads it as a transparent shape without any appearance attributes.
    Now I have a shape with a stroke, I want to change the stroke color by sampling the colors on the image.
    You can't do that with the eyedropper because the image doesn't have a stroke.
    Eyedropper only picks and applies appearances.
    So I guess you can't do this in Illustrator from the beginning.
    The eyedropper isn't built for that.

  • How can I select and delete the fill color (white background) of a live trace (B&W) with in an actio

    How can I select and delete the fill color (white background) of a live trace (B&W) with in an action set?
    Illustrator CS4 in windows XP.

    Maybe Li[ve trace] is not t]he way[ to go
    I have some suggestion one leave it as is and use a blending mode of multiply to give it a color background like this
    leave it as is make it a grayscale tiff import int Illustrator and color it it in Illustrator like this
    Or trace over it with the brush tool aand then give it a color ground.
    Or do the original over and do a cleaner job with no tone or a minimum of tone. Then Live trace.

  • Can I change the fill color of an entire row based on what's selected in a pop-up menu in the first cell?

    I have a pop-up menu in the first cell of every row with three choices (and I may add more at a later date).  I want the fill color of the row to change depending on which thing is selected.  Is this hard to do?

    Hi,
    In essence the same as Wayne's answer, but with a slight modification to fit  to duplicate your 'color the whole row' specification. The final result, with Table 2 slid behind Table 1, is shown.
    Table 2 is a single column table with the same number of rows as Table 1. The table is resized to match the full width of Table 1.
    In A2, use the formula =Table 1::A2 to copy the value from that cell in Table 2. Fill the formula down through the rest of the column.
    Select all the cells in Table 2 (except the header row), and apply conditional formatting rules such as those below.
    Note that the Conditional Format rules are set to apply the same colour to text and fill in the cell, so that the text disappears.
    When Table 2 is ready, select it, then go Arrange > Send to Back.
    Before sliding Table 2 behind Table 1, Select Table 1 and use the Table Inspector to set the Cell Background to None (see red arrow in illustration). If This table has a Header column, you need to select the header cells independently and again set the Cell Background to None.
    Now select Table 2 and drag it to a position partially under Table 1. When you see the blue alignment guides on both sides, or at the top and bottom, of Table 1, release the mouse button and use the arrow keys to nudge Table 2 into its final position.
    Regards,
    Barry
