• I need to import 3 different images in a control of the ring who align properly

  I want to design a 3 switch channels using 3 different images in a ring of photo to represent each of the 3 positions of the switch.  I can't get these images to align properly for this because they seem to stick in the control of the ring with different coordinates. How to achieve this alignment of multiple-image?

  If the reason was by selecting the whole picture.

  Seems to me best way to copy Edit-> import the image into the Clipboard. In this way, he treats transparent color correctly and imports a complete image.

• How do you replace the values in a control of the ring?

  Hello

  I have a control of the ring (text values) in Labview 2009 and it is populated by programming with 20 points. The end user selects from the list items or fills with a new item based on a checkbox to add a new item. What I want to do, that's when section 20 is entered and the user selects the check box next to the point 21 to add I want around rap on the first item in the list and crush him. Is this possible and a sample VI would be great demonstrate how this is done. Any help would be greatly appreciated!

  Thanks in advance

  Replace the subset of the table.  You need to keep track of the element to replace in a shift register.  I would also like to keep the list in a shift register to make your life a little easier.

• Weird problem with control of the ring and foot

  So I have some sort of weird issue with a control of the ring and a chart. I'm with LabWindows/CVI on a Windows 7 computer. The part of the program I'm looking at is basically to navigate through data - there are several "transition" (rehearsals experience), and you can choose the one that you want to watch in the list.

  Normally, you would select transitional in the list, it plots the data, then it is done, basically. However, all of a sudden (don't know how long it spent for), when I select anything except 'Average', he made all the tracing and such, then it changes control of the ring to 'Average' (it is not plot the average data or generate all the reminders that I can tell).

  Now the thing the more bizarre as you can see below, it seems that the switch happens just when I draw something on the chart:

  

   

  So, it's just weird. The code in this section is here:

     if(uidc.polyon) {
              polynomial_subtraction(curr_data, np, uidc.polyord, 0); // 0 Skip for now
          }
  
          // Scale the curr_data for gains, then pre-scale the FFT data
          // to have no change in the power spectrum (multiply by (2/np)
          for(j = 0; j < np; j++) {
              fft_data[j] = curr_data[j]*2/np;
              curr_data[j] = curr_data[j]*uidc.fgain[i] + uidc.foff[i];
          }
  
          uidc.fplotids[i] = PlotY(dc.fid, dc.fgraph, curr_data, np, VAL_DOUBLE, VAL_THIN_LINE, VAL_NO_POINT, VAL_SOLID, 1, uidc.fchans[i]?uidc.fcol[i]:VAL_TRANSPARENT);
  
          // Prepare the data.
          FFTEx(fft_data, np, npfft, NULL, FALSE, curr_fft);  // Do the fourier transform
  

  DC is a structure that I use to better organize some UI controls and uidc is for display RAM variables, then dc.fid is the Panel that is embedded in the tab "FID", dc.fgraph = FID_Graph and corresponds to the chart control. Control of the ring is actually in a child Panel, dc.cloc [0]. FID_Graph has a point, it can produce, but the reminder is empty (no not coded something there yet).

  I have also considered that perhaps something in another thread (I don't think there is, but whatever) I see is the cause, however, this behavior still happens on that line. I tried to break in different locations, on hold, then continues, as well by adding a loop containing Delay (0.01), a loop of 100 times. Always happens after the conspiracy.

  Does anyone have any idea why this might be happening?

  Hi Paul,.

  I don't have a solution, but I wanted to point out that, even if you see the ring to change its value only when you call the function of tracing, that doesn't say what this function call that really changes the value of the ring. In CVI, some drawing operations are batched, for performance reasons, and the Panel updates only visually at certain times. One of those moments when you draw a chart data. Yes, the ring changes visually at this time there, but it is probably just 'catch up' a change earlier.

  As you are looking through the code, when the value of the ring, you can use the term > command update UI to force the update panel, so that you don't have to wait for the tracing function and see if all goes well this change happening earlier.

• Import data from text file of control of the ring.

  Is it possible to import data to a text ring with labview control.

  I have several definitions of register in the ring controls, but manual entry would take a lot of time.

  Was wondering if there was more automatic way, I could read the values from a file.

  Thank you

  Jim

  Using the first method gives you the ability to extend such that each column specifies a control of the ring if you need fill the multiple rings.

  This example assumes that all of the three rings contain the same number of elements. If this isn't the case, you will need to create a Subvi, which removes the empty elements. [Edit - create a text file that contains a column for each ring, separated by a tab character.]

• How can I change programmicly a control of the ring?

  I have a test system that supports many products. Furthermore, I frequently add new products to the list of support. I have a control of the ring that lists these products. I wish I could have my program automatically read a configuration file and change or add to the checklist of ring of all new products found in the configuration file. I wonder if anyone has tried this. Or is there a better way to configure an adaptable system to accomidate what I want to do?

  In the diagram that I have attached, I add an item to the variable of the company and set the value to the new addition.

• Get the current value of a control of the ring

  

  I have a control of the ring that has the following values. See attacment. I need to get the current value of this one and use it as input for another function, but First I would like to get the current value and save ina text file. I tried this

  if (event == EVENT_LEFT_CLICK_UP) || (event == EVENT_LEFT_CLICK_DOWN)
  {
      int p;
      GetCtrlVal (panelHandle, PANEL_RINGSLIDE_1, &p);
      FILE *OutFile = fopen("C:\\Users\\Student\\Desktop\\ringtest.txt","w");
      fprintf(OutFile,p);
      fclose(OutFile);
  
  }
  

  I need to get the current value of the ring (& p) to write to the file ringtest.txt.

  Also, I need to use this value (& p) as another entry in the same program.

  IE value of & p must be used in

  b = c * 5; where c is the value of the current & p.

  Can any 1 help?

  You're right: EVENT_LEFT_CLICK_DOWN is not a valid event for the CVI. Valid events are listed in the userint.h file, and are the only events that can be caught in the trap in a point of order. On the other hand, you're assuption on EVENT_VAL_CHANGED is correct: you can trap forget the EVENT_CLICK_UP event.

  According to the second question, looking at the definition for fprintf you must pass a string format as the second parameter to the function, then the value to write to the file. In your case, the correct syntax is:

  fprintf (OutFile, "%d", p);

• Keyboard and a chain of control to the screen

  I feel a strange behaviour when I use the keyboard (OSK) and a chain of control on the screen.

  I develop an application that you can use the OSK to enter some data on a touch screen with no physical keyboard. I have a Machine to States Event-Driven set up at the key event to the bottom when a word/characters are entered and the user presses the Enter key on the OSK. I noticed that if I probe the wire wuen Vcle I press the Enter key on the OSK, it appears like a back press. Not much, I thought, just to see if the Enter key is pressed and continue on.

  When I went to test my program, I noticed that my values were as if nothing has been entered. Digging a little further, I noticed that my original data are still there if I press the BACKSPACE and delete the return order. Probe string wire in the control of the chain indicates that the value comes back as an empty string in my control channel even if my entire string is physically still there. I can press the BACKSPACE (remove the carriage return) and see my original text. What, in my view, that happens, is when I press the Enter key on the OSK, it inserts something and moves my text upwards or downwards, and when I use the node property to retrieve the data in the control of the chain, I get an empty string.

  How did you get around this? I would like to hear your solutions.

  Have you tried right-clicking on the control of the chain (assuming that it is "ID mould to enter") and by assigning the value 'limit to the single line "? Sounds like your settings cause hit enter to add a line instead of the finish of your entry change. (You can also change the behavior of 'back' in your settings of LabVIew)

• Programmatically set the size of a table control (not the number of col and lines)

  Hi all

  I am trying to create a little VI, in which the user selects the number of columns and rows in a table, and after clicking on a button 'OK', the table control is displayed in the control panel (to be filled in by the user). To do this, I use the nodes property to the number of columns and lines. I have no problem with that.

  However, I want to "limit" the size of the control table (control of himself, not the dimensions of the table) and make use of vertical and horizontal table, the scroll bars. I want to avoid it is that passes type 100 user and 100 lines and appears a huge table control.

  I could tho this by using an array instead of an array, via the node property "size", but I would use an insead table a table.

  Thank you very much

  Daniel

  With a table control, you cannot set the display size to be anything other than a multiple of a complete cell.

  If you are limited to a number of lines and columns.  If you want to resize with more control you also need to resize the control within the Bay, accessible via the property 'picture Element '.

  Another option (but seems huge exaggerated) is to place your table in a secondary and set the size of the secondary to the size you need and enable scrollbars for her.  It is not an option that I would choose but if it helps...

  Have it, your description of your user interface sounds not very intuitive.  How the user knows at any time exactly what cell they access if they have to scroll backwards?

• Get lost with the controls on the panels

  Hi all,

  With the help of Lavwindows 2010

  I have a little difficulty with my UIR.  I inherited a project with several panels, 2 have about 340 controls on each of them, I'm looking at (for example) a certain (RATE) control properties. I use the tree Panel to get the table I want and the FREQUENCY control.  I double click on the name of the control RATE.  In the details (under the tree Panel) section, it shows the name of the constant is MLED_MAX12_2 and its status led (its really a digital slide).

  Is it just that CVI has trouble with panels containing a large amount of controls?

  Is there another way for me to access this control? (right click on RATE and by selecting OBJECT UI FIND gives me the properties of the control MLED_MAX12_2.

  Is there a limit to the number of controls on a Panel? of the project? File of the UIR?

  Thank you

  The solution is to change the control in the edit control dialog box that appears when you click on , when a control has focus in the editor the user interface with the editing tool selected (as opposed to the tool of exploitation). Or you can double-click the control to display the edit control dialog box.

• menu bar popup not working if the focus is on the control of the chain

  Dear all,

  I wonder if this is the behavior expected or if I'm doing something wrong:

  On a Panel, I have a control of the chain; on double click, I opened a file selection box to select a file, then the file name on this control of the chain. After this action, this string is the active control, indicated by the gray frame.

  I also have a menu with some defined keyboard shortcuts bar for example F2. It seems that F2 is not functional, long as the focus is on the control of the chain. It's embarrassing because the typical user action is selects a file and then pressing on Fx. To resolve this problem, the user should click somewhere on the Panel to move the focus to another control. Of course this could be done programmatically, but the extra effort is not to say necessary for controls ring or digital controls. Also in digital controls, I can change the numbers, but even if a digital control is the active control due to the edition of the F2 value works immediately.

  Help is appreciated.

  Thank you

  I think what is happening here is that left double click is also used to highlight the text. So when you trigger the EVENT_LEFT_DOUBLE_CLICK, you're placing the text in the control of the chain and then also accentuating. It seems to be behaving strangely when the two of them occurs at the same time because of the order of the events. You can see that the mouse around when, returning from the file select popup causes the region highlighting to drag over the text. In this highlight mode, you cannot use the shortcuts for the menu. I was able to solve this problem by swallowing the EVENT_LEFT_DOUBLE_CLICK after you set the value of the control.
