• How to set fire to a single event "mouse down" when a tab control and its digital control have all two events 'mouse-down' with different function

  Hi all

  I have a digital control in a tab control. Both of them have their own events 'mouse-down' in a while loop. But when I click on the digital command, instead of raising the event of digital control only, both of these two events fired.

  Maybe I can check if the mouse is in the range of digital technology to filter events, but if the window is resized, I have to recalculate the range once again.

  Is there another way to do it?

  I pasted the test code too.

  Thank you!

  Excerpts of work

  

  Side note: I really don't like the controls on the tab and use them very rarely.  And the few times I use them, it is for tabs to which I often use to select among the screws to put in a secondary school.

• Problem with the format of the values in the command prompt (when you use multiple values)

  Hi all
  
  I have problem with the format of the values in the command prompt when you use multiple values.
  
  Value is year (2009) and when I use it in the drop-down list that is formatted, all right, as 2009, but when I use several values I get number as 2009,00. I put in year column format number with 0 decimal places and save by default in the year column. Year is formatted well anywhere in the query, such as 2009. Why is - what happens at the command prompt when you choose multiple values in prompt dashboard?
  
  Thank you

  I think the YEAR Data Type could be defined DOUBLE RPD.

  Use the CAST function in the formula (fx) and the output from test.

  CAST (INT YEAR)

  Hope, it will help you.

• Case of event Structure to manage the value between

  I put in place a structure of the event to enter data in a multicolumn listbox.  I wanted to use a table, but it was difficult to place symbols in the first column; even using the odd fonts (Webdings, etc.) to get check marks, x, etc...  I don't want the user to change some of the columns, so a MCL with a structure of the event to detect user input works well in the test code.

  When the user clicks on a cell in the LFA, then I place a transparent control chain on the cell of the same size, so the user, it seems that they enter data.  I pre-fill the chain with the existing content of the cell control and site selection at the end of the string.  After you enter a string, the control of transparent string is moved outside the LFA, so all the clicks of the mouse in the LFA are always detected.  It all works very well.

  If the user changes the value and press 'Enter' or click on the button Enter text under the file menu check box, the structure of the "Change value" event triggers then.

  If the user keeps the same value and presses 'Enter' then the structure of the 'Touch Up' event where ScanCode = 28 detects the press 'Enter '.

  However, if the user wants to keep the same value and presses the button check box on the file menu and then the structure of the event does not detect it.  I added a bunch of advanced control of the chain, but if the user moves the mouse away from the control and then the tip appears only for a few moments.

  Some of my users are used to click the box to enter the channels, so I'd like to understand how to handle this event.

  What can I add to the structure of the event to detect user maintaining the same value by clicking the checkbox?

  Thanks for any advice.

  P.S. I'm using LV 7.1 because my startup employer cannot justify the money to upgrade right now.  Yes, in more modern versions are nodes property to indicate the line & column clicked in a MCL, but I don't have access to it, so I use the position sizes and the row/column of MCL up/left to determine what cell they clicked in.

  You could hide the toolbar of the VI during the race, this disables the option click on the button "enter".

  Or you can run a small loop to see if the string still has key-focus, I discovered that when you enter the main focus is removed from the control of the chain.

• structure of the event recorded does not change value

  I have a VI that communicates with an FPGA via a telnet interface.  I have several Boolean controls on the front panel.  When you click a control, it sends a write command on the face i in telnet to the FPGA.  Similarly, if a process in the FPGA himself wrote the same registry (that control written when I clicked on it), an order is generated in the FPGA and returned to the VI and the control (via a local variable) lights or unlights accordingly (based on value).  In other words, these controls are read-write...

  It's all workers, except for one important thing.  I have the code that runs through a structure of event whenever the value of the control changes.  I can see that this code executes in fact when I click on the control via the front panel.  HOWEVER - when something is generated in the FPGA finally changes the value of the control, the structure of the event does not, even if I see the value of the change of control on my front.

  A specific example, I have a control named CLIENT_LB.  When I click on CLIENT_LB, I see it lights up, and I see the event structure code run.  Now, if I have the FPGA process to set CLIENT_LB to 0, I see unlight on my front, but does not run the code structure of the event.  I have probes in place who have checked the associated local variable CLIENT_LB evolving impact of values.  The structure of the event reads: 'CLIENT_LB': value change.

  Shouldn't an event structure "value change" run when the value changes, regardless of whether if it happened manually (i.e. me by clicking on the control) or automatically (i.e. the FPGA written in VI and changes the value of the control)?

  The VI is great, and you would not be able to test it in any case unrelated to the material, to remedy that I've attached 2 screenshots, I have described below.

  1. This is where the string from the FPGA analysis occurs.  The chain between the sub - VI, and then the data chain part is hidden to determine if the Boolean value of the control is true or false.  I put a probe on CLIENT_LB, and I see that as the FPGA changes the value of the register, CLIENT_LB passes from false to true as a result.  I checked this several times.

  2. it is the structure of the event.  This code runs when I click on CLIENT_LB on my face, but does not run when the peak CLIENT_LB #1 local variable is changed.

  Writing to variables never fires events to "change the value. If writing should raise this event, use the property "Value (follow the signs).

• Hovering over the triggers Drop Down Menu event "mouse Leave"

  Hi, if anyone can help with this problem, I would be very grateful.

  I have a tab control changing to another page when the user enters or mouse leaves the tab control. The purpose of this is so that the tab control becomes invisible when colored 'transparent', according to the movement of the user's mouse. This allows the full screen to use to display the video when the menus are not necessary, and menus can be displayed when the user enters into the surface of the tab. There is also a button to lock the menu in place.

  It worked fine until I added a few rings of text to a menu tab. When the user clicks on the drop-down arrow and hovers over the elements, the case of the event as if the mouse has left the tab control, tab resets back to page 1 (white page). I don't want to do it, but I still want to use the drop down menus because they are more concise and more convenient than the alternatives (listboxes, etc.). This does not happen with the buttons and other controls, only with the drop-down menus, AFAIK.

  Can anyone suggest a work around? I chose this method of relaxation because it is less demanding in processor using the mouse move event coordinates to trigger the tabs appear. I need to save so much time processor for video capture possible. I enclose my vi (Labview 2010 32-bit) with the gray tabs so you can see and test the value for yourself.

  I would add one for the event to "Operate the Menu Activation" for the controls of the ring.  This simply fuels a real constant in a shift register in time loop.  In the mouse enter and leave events add a case structure and change the pages only when the value Boolean false.  Ensure that supply the true value in the registry to offset in the mouse leave case also (other cases may use the Default of False if you don't have to string wires in all cases).

  Quick MOD after extraction of the stuff IMAQ, remove also the delay in case of loop Structure, provides it ARE necessary delays.

• Problems using the event to write new parameter values to VISA structure

  Hi all

  I created a VI to read an Omega flow meter. It is possible to change setpoint (setpoint (0-2) SLPM) of the meter and the gas (O2, CH4,...). To read instrument I write its ID (A-Z), followed by a carriage return, for example: A + 0x0D

  I created a VI with the events to write only the parameters to the instrument when a value is changed. My VI works but from time to time, it does not write the parameter change (gas or set point). I think that is has something to do with the while loop containing an entry VISA.

  Open FMA contains parameters and VISA opend

  Case of timeout initialize writing gas and setpoint for the first time

  Other events are for the change in the value of setpoint and gas

  How can I make sure that any change of setting will be writtent the instrument?

  Thank you

  Salvation Bass,

  Well, it is true that I lose this way time-out feature.

  No, you do not lose this feature. You put in a different position.

  You must call it BEFORE your loop!

  I'm not sure that I am following on this one there

  Why are you not sure? You have a large number of constants "0d" and it would be great to see that they are displayed in HEX mode instead of the normal display mode.

  The new VI manages events sometimes... but sometimes, missing a few changes... I think it is because there is an entry in the while loop. Do you have any idea how to prevent this?

  Never, NEVER use parallel loops to write and read on the same device on your serial port!

  How do ensure you that you always get the right answer to your order sent before?

  What is the purpose of using a second loop here? A loop with no wait States?

• Write multiple events created for a single value (signaling)

  Hello

  I have a program that checks continuously to check if a given amount of time has passed (e.g. 10 seconds). I pass the Boolean result to a case statement. In the case of FALSE, do nothing. Inside the case TRUE I wired the switch entry dealing with a property node: Val (Sgnl) in order to trigger an event. The actual value is not important, I just use it to trigger an event.

  When you view the event inspector window, I see two events are sometimes created at the same time, which causes problems in the rest of my code. I have the option 'max limit Instances"checked in the menu change events, as well as the number of Instances the value 1.

  Can someone please explain why this is happening and recommend a solution?

  Thank you.

  -Natsfan

  Add a wait of 1-2 ms to the loop in your main calendar.  It is conceivable that the loop takes less than 1 ms to run and you see the same time at two subsequent iterations of your loop and that's why you get sometimes two close triggered events

  I would not use a separate at all, but directly control the timing of the event timeout.

• Trigger several events to a dynamically saved value of signage

  I have different controls for some pumps.

  I want to stop all with an emergency stop button.

  I use the event Structures to manage the user controls.

  In the previous version of my code, I register all events statically in the same vi. But to make the program compact and modular, in the attached version of the code, I use the references to the controls, and I go to a Subvi. In the Subvi I record the events of these references and I link the "event recording refnum" to the terminal dynamic events of the Structure of events.

  Everything works with the exception of the emergency stop.

  I can't use a reference of the emergency stop button to trigger the event, because the emergency stop opens the other files in vi for further confirmation from the user.

  When the emergency stop is confirmed by the user, I use the value property of a signalling to trigger the event stop of all structures event of the subgroup on the screws that control the pumps.

  Previously, I had only a single value of signage to trigger several events, but I saw that I have create the condition of critical competition and the Structure of events first, which handles the event, removes it from the queue, and other Structures of the event can't get the event.

  So, I use as signals of many boolean value pumps as much as I.

  But it does not always raise all events.

  Another detail, it is that I do not use the "Unregister for events function" in all the screws under that have Structures of the event. I saw no difference with this function, or without him...

  Apparently, Miss a clue of a general principle of LabVIEW.

  I join all of the template project.

  The main.vi starts the program.

  The problem of this thread is re-posted more clearly and it is resolved here:

• Event just after obtaining return value of lov inline search page

  Hi all

  I created a lov inline search, my page looks like this:

  

  When I search and select the result I want.

  

  I get this result selected as back to my point of return of my page:

  

  What I want is:

  At the time when the page is displayed to show me the value selected, I want to show him something else on this return value. For this I need to know what the event or the setting I need to take to whether or not the selection is made.

  I hope I made clear what I need

  Thank you very much for your help

  Kind regards

  Afaf

  Not really sure what you are after. You can try this.

  If (PageContext.isLovEvent ())

  {

  String lovInputSourceId = pageContext.getParameter (SOURCE_PARAM);

  If ("".equals (lovInputSourceId))

  {

  }

  }

  See you soon

• DoubleClick event mouse can't register

  I extended the Panel class and added an event (MouseEvent.DOUBLE_CLICK) listener to the title bar, but I can't get this fire. I tried other mouse such as CLICKS, MOUSE_DOWN and MOUSE_OVER events and they all will fire as expected. But when I try to use double_cliquez it does not fire.
  
  Is this a bug? or is it because of other reasons, like double click isn't cross and 2 simple clicks go?
  
  Any help would be appreciated, thanks.

• Browsing through the values of multi-donnees block against certain values BEFORE UPDATE! (FORMS 10G)

  I have a form with 2 blocks: a tabular and a single.

  I need to check a condition before INSERT/update to each record.

  To insert, I do this in WHEN_VALIDATE_RECORD and its working perfectly fine.

  However, to insert, as only the updated records are validated if its does not work very well against all records.

  How to browse and check all records against a condition on the UPDATE.

  I tried go_block, loop, depending on type of logical record in pre_update and pre_commit, but they are limited to these triggers.

  How to solve this problem?

  Kind regards

  Misbah.

  What I mean is that you must take logic out-pre - COMMIT because you can't do a GO_BLOCK.  Instead, you need to transfer this logic in triggering the COMMIT BUTTON.  It is not limited, so he can make the GO_BLOCK, NEXT_RECORD, etc...

• In what order are anchor command left and right control point values returned by entirePath()?

  The entirePath() returns the anchor points that have two values, or it returns an array with three coordinates. I would like to know, in this case, what is the point of anchorage, control point index and values of point of order from right to left?

  The three values are leftDirection, the point of anchorage and directed. 'leftDirection' and 'directed' compete in the competition for the worst property names, because they have nothing to do with the left and right. Publishers of fonts and other programs that deal with the use of the perfectly transparent Bezier curves "in" and "out." These words make sense. Adobe of not.

  To find out what values stand for, draw a simple curve with three points, then use a script to write the values to the console of the ESTK. Open the transform Panel and check the values it that that you printed in the console.

  A major problem in all of this, is that when you select a point with the direct Selection tool, app.selection [0] does not return this point (I forget now what it returns) and get a handle on a selected point is an ugly hack.

• Validation form column against the value of another Table

  Hello

  I'm new to this forum, so please bear with me a bit!  I only have a small amount of writing PL/SQL experience, and I've never written Javascript or JQuery before.  I am an Oracle DBA and I coding experience C and PERL, so I have a strong technical background.  But I need some advice on the best way to approach a problem.

  I have an application of data base in Oracle Apex (version 4.2) with a tabular form on a table: Let's say that #1 with the conditions of licence 1 a, 1 b, and1C.  I have to make sure that the value entered in col B is not greater than the value of a column in another table (for example table #2 pass 2 (a).  From a conceptual point of view, the amount of money available is in the #2 table, and my tabular form lines are an act of spending money (such as orders or invoices), so I have to make sure that we spend more that we have.  Who is?

  Does anyone have tips for the best way to do it?  I'm figuring that the biggest problem here is perhaps to account for people who enter multiple lines in the form of tables at the same time, right?  So, if a person is entered 3/invoices, I need a total to ensure that they do not have spend more than we have in the #2 table.

  I really appreciate your help!

  Best regards

  Laurie Baublitz

  Ah, I was not totally with you on this charge then. My validation works overall, but it totals the amount for each line, regardless of the task. Okay - who was not totally my solution but more a demonstration of the technique that you can use to validate your tabular presentation in this way.

  You could solve this issue with a safe collection, or with a table plsql where you add an entry for each task name and keep the amount stored in there.

  Anyway, it would be better for you to spend a little time on playback on the plsql collections or collections apex!
