Arrow complex

Hi guys,.

I had the following problem... and it seems to be rare as (at least I have found no suspicion but that works):

I want the user to enter a complex number using graphical means (2D compass draw or XY-Graph). In the version of the range the user is supposed to click on a Point in the diagram. As the program acknowledges this, it fills a vector/arrow pointing on this point and starting to analyze the data entered.

But I had trouble reading the data that I put in the chart. So far I tried to convert the data of Compass 2D in an "every-day-Datatype' to progress further, but failed epicly it already.

In detail, I went to "compass D-Online Index Array ==> get variant attribute ==> converted to a string as well as the Variation of these various.»

My hunch is that I use 'Get variant Attribute' simply false

Someone has any idea how to solve this mess?
Has a value of compass which attributes?

Greetings

PS: Attached, you can find a picture of my last try to get the name of the attribute. Needless to say that it does not work so far. The structure resembles the other tries.

Make a control chart is pretty useless here, then let him as an indicator.

I never use the fancy graphics, because they appear to be relatively limited.

Instead, use a plain XY graph and mouse events which gives you the coordinates in pixels. You can easily convert between pixels and appeal of xy coordinates using nodes.

I also recommend that you attach a real VI instead of an image. What is your version of LabVIEW?

  • The arrow keys sometimes does not work in text boxes

    I have a recurring issue which is really annoying: my left/right arrows (including CTRL + arrow keys) randomly and occasionally do work not when entering text in some text boxes on some Web sites. This never happens in unformatted text boxes 'simple' (Facebook, search fields, this box very I type in...), but unpredictably longer complexes (WYSIWYG editors, new comments youtube...).

    I tried to disable all extensions and run Firefox in safe mode and it * seems * have solved the problem, although I can't be sure and I can't isolate which he might be, given that the problem occurs randomly extension: on the same site, it will happen and then not happen.

    I'm on Firefox 25.0, although I've had this problem for years with countless versions of Firefox.

    The extensions I have installed and enabled:

    Like Adblock
    Bamboo Feed Reader, dimmer, Download Helper, Drag & Drop Zones, Flagfox FlashVideo Downloader, Flashblock, Flashgot, Grab and Drag, MouseZoom, status-4-Evar, Youtube HD

    Thanks in advance for any help you can give me.

    If it works in Mode safe mode and normal mode with all extensions (Firefox/tools > Modules > Extensions) off and then try to find which extension is the cause by allowing an extension at a time until the problem reappears.

    Close and restart Firefox after each change via "Firefox > Exit ' (Windows: Firefox/file > quit;) Mac: Firefox > quit Firefox. Linux: Firefox/file > exit)

    In the Firefox Safe mode, these changes are effective:

    • all extensions are disabled
    • Default theme is used (no persona)
    • userChrome.css and userContent.css are ignored
    • default toolbars is used (localstore - safe.rdf)
    • JIT JavaScript compilers are disabled (javascript.options. * jit)

  • HP50G equations w / complex real Vars & solve for reports of Vars

    Hi guys. I have 2 questions.

    1. given an equation with a variable complex and variable real in it, I want to solve for both variables. Here is an example

    Given:
    ∠120 has° + jb =-4 + j3

    Solve for A and b.

    Answer:

    A = 8
    b = -3.93

    I know it's possible to solve by hand because A is true and b is complex. But I don't know how to do this on the HP50G because the equation has two variables inside.

    2 it will probably be a bit more complicated. Saw 2 symbolic equations, I want to solve for the report of two variables with respect to the other variables. Here is an example.

    Given:

    (X Z) / Q + (X - Y) / (X - Y) + R / Q = 0
    / Q (X - Y) = Y/R


    Solve for Y/Z depending on X, Q and R

    Answer:
    Y/Z = [/(Q+R) R] ^ 2

    I'd be very impressed if anyone can understand these out or already knows how do the following.

    Thanks in advance!

    Hello

    (1) :

    It's my approach:

    Settings of the calculator:

    -angle mode: radians (required for the Solver)

    -coord system: rectangular (my choice as it fits x + y * i).

    -Digital and about unchecked

    -operating mode: RPN

    -Flag-27 value complex display that x + y * I

    First angle must be converted to radians, 120 deg = 2/3 * PI radians (PI can be entered as WhiteShift SPC).

    Enter ' (A, ∠2/3 * PI) + B * i =-4 + 3 * I '

    I use 2/3 integers to facilitate the exact mode of address, shortened to ∠ is ALHPA, redshift, 6.

    That the calculator is in rectangular mode, it will be transformed into rectangular.

    You should now have:

    A * COS(2/3*PI) + A * SIN (2/3 * PI) * + B * i =-4 + 3 * I

    Now, press ENTER to duplicate the equation.

    Go to WhiteShift MTH, CMPLX.

    Select RE for the real part:

    A * COS (2/3 * PI) =-4

    Press SWAP (silver arrow)

    Select IM to the imaginary part:

    A * SIN(2/3*PI) + B = 3

    You should now have 2 equations on the stack (the real part of level 2) and the imaginary part in level 1

    You can now put them in a table (2,-> TABLE) and use the Solver to solve for A and b.

    NOTE: when you use real numbers instead of integers, you may use the digital Solver of multiple equations MSLV (NUM. SLV). This requires a set of initial parameters i.e. guess (see Chapter 7 of the great user's Guide or MSLV AUR).

    (2) :

    You cannot resolve Y/Z directly. However, you can solve for and there, Z , then simply ÷ to get Y/Z.

    Level 2: [(X-Z) / Q + (X - Y) / (X - Y) + R / Q = 0 (X - Y) / Q = Y/R]

    Level 1: [Y - Z]

    S.SLV, point 6 or F6 to SOLVE

    Will result in a list or a table that contains solutions for Y and Z depending on X, Q and r. use OBJ-> once or twice to put both equations separately on the stack, then press fracture for Y/Z.

    Note, you can change the representation of the solution by the factor or simplify (best way to find who is to press down arrow money to enter the Equation Editor, select the right side of the eqation then de FACTO or SIMP).

    I hope this helps.

  • Generator of arrow and transitions more for first?

    I'm in from Final Cut Pro, that I used for years to make videos. In these videos, I draw a lot of circles around things and reveal with a clock wipe (which makes it look as I paint them), and I also do the arrows (with a generator of Stibs arrow) I reveal with a cloth edge, which makes the arrows look like they're stretching to point at something. And so on.

    I'm just my first taste of first, but I don't see any generator of arrow, nor most of the transitions that I used. In fact, compared to the CPF, there seems to be a great lack of transitions in general for the first. Is it possible to add shape and arrow generators and transitions to first?

    I really want to use the first, which looks like a great video editor, but if she does not have the tools I need, I guess I'll have to go to Final Cut Pro X, which I really wouldn't do. First is a little like the PCF in many ways, so it seems familiar and I can see the skills, and, after Apple yanked the rug out under me by quitting Final Cut 7, I don't want really to stay with them if I can help it. I no longer trust them.

    Thanks for the advice, everyone. I will learn and use the first, all right, but now he just can't do things for my video tutorials, like generate arrows and circles and reveal transitions, things I can do easily in Final Cut 5, not to mention the lack of transitions in first. I'd stick probably with FCP 5 wasn't for the unbearably long travel times on my slow and ancient G5 computer.

    As for 'wanting features of FCP in the first', well, this elegant Stibs arrow generator I described was not a feature of the FCP - is a free plugin created by someone named Stibs for first FCP. accepts plug-ins too, I noticed, so where are you now, Stibs, when I need you? Where is someone who can give me such a generator of arrow? I'll buy it!

    I see that the generators for the arrows, boxes, emphasizers and all sorts of things is available for Final Cut Pro X, for example, the rippletraining.com in a plug-in called "legends". Their ad says: "legends is a X BVOT Final Cut plugin that puts the power of focus in your hands - add arrows, shapes, magnifiers, animated map of trajectories, speech and thought bubbles, lists of control and more for your video project."

    So, where is such a thing for first? I took a glance at the interface of final cut PRO X, and it seems difficult and complex compared to the PCF and first (clips are called "Events" among other things of hazelnut). I can understand and use the first after years of use of FCP, but I have to learn a new vocabulary and interface to use FCP X, not to mention spending $300.00 to buy the program.

    What I've seen so far from first looks great. For example, another thing I do often in tutorial videos is zoom and panning around on still images - to the thing "Ken Burns". 5 PCF, the movement pan / zoom is jerky, with sudden starts and stops and it is impossible to flatten them. But I see that there are ways to move smoothly and gently on the stills and make incremental changes in the speed of clips in first. Wonderful! But I'm still paralyzed in first by the tools of insufficient graph for educational videos, darn it.

  • iOS 10 mail for iPad lack up/down arrow in the header

    Put JJust to upgrade to iOS10.0.2 on my iPad. There no message before or after the arrow in the header. How to make a comeback?

    Hey there, oldregistrar!

    Thank you for using communities of support from Apple! It seems that the Mail app on your iPad on iOS 10.0.2 does not display e-mail messages in its entirety. I'll be happy to help you.

    Force an application to close on your iPhone, iPad or iPod touch - first of all, use the following instructions to force it to close the app email, and then restart your iPhone, iPad or iPod touch - never underestimate the power of a good restart.

    If these steps did not help, which is / are providers of email, what other measures have you tried?

    Take care!

  • How can I add a map page in photo books that will show destinations with arrows like iPhotos used to do?

    In iPhotos, you can create a page of book that showed cards with your travel destinations. The kids loved because they can now see to what extent they traveled. This feature doesn't seem to be transported on the photos App updated. Can anyone explain why?

    You can add a map with markers places, but arrows like in iPhoto or Aperture are perhaps not available, because the pages with arrows caused constant crashes in iPhoto, who knows.

    As a workaround: you could create a map with location markers page and print the page in PDF format, and then draw the arrows in preview on the map and import the page map of pictures as a photo.  Add this photo to the photo book full page.

  • Reverse arrows message next/previous iPhone mail?

    When reading an e-mail inside the Mail in 10 iOS app, email previous/next on the upper right arrows are configured differently from most applications of e-mail (Gmail and Outlook, in particular) and it is the engine of my brain coconut.  Left arrow goes to the previous received email - that would make sense, except that it is in contradiction with the sorting of the list of email, which shows the most recent email on top.

    Is there a way to reverse the function of these arrows based on my preference of sorting?  As my most recent emails are at the top of my list, I would like the left arrow to move to the TOP of the list and the right arrow to move to the BOTTOM of the list.

    Hi Agrahman, unfortunately, it seems that you are asking to move built-in IOS features. While you can rearrange how your emails, it is not possible to move the top arrows because they are supposed to be integrated the app and the app itself is built in the iOS 10

    But you can always set your iCloud account using a different email provider, or by downloading a more convenient mail on the App Store app

    Hope that helps!

  • MacBook pro 2 logon screen starts with no arrow cursor and must be restarted

    2014 Macbook Pro screen Retina 2 13 "opening session starts with no arrow cursor and must be restarted once every five tests.  When the computer reboots, message appears asking you if it must open programs that had started to load or cancel.  It is a recent problem that does not occur two months ago.  Once restarted, everything seems to be OK.  That is what it is?

    Try the start mode by holding down the SHIFT key at startup. Secure boot is quite slow because the operating system performs some cleanup and verification tasks, so give it time. Once you're completely connected, restart normally.

    Hello. I edited together a set of volleyball clips in iMovie version 10.1.2. Try adding an arrow highlighting of my daughter. I have created a freeze frame of the clip where I want to put the arrow, the arrow as a .png, you drag the arrow on my clip, green image '+' indicates where I understand I should be able to expand and choose "picture in picture", but I'm not introduced this option. The only options I get include the replacement of my clip with the new image. Here, any help would be appreciated. Thank you

    Place your overlay .png above your clip, and select it.   In the toolbar at the top of your screen, click the button that looks like to the overlap of the squares.   A selection box which appears when you click on it, will give you the picture in picture option.    Click on that and move the playhead on your clip to let you be your overlay appears in the clip. (You may need to click the blue reset button to the right.) You can then adjust in the size and position.

    I hope this helps.
