    web server

    I am reading a couple of tutorials on deploying an application as a web service and noticed that the instructions obviously are for a windows environment and refer to using the Silverlight browser plug-in to 'enable and configure the Application web server'. I am using LabVIEW 2010 PDS on a linux machine and will need instructions on how to do this on a linux machine.

    execution error

    I have linux 2010 PD systems installed on two CentOS 5.3 OS systems. On one system I have a fairly large project that compiles and run from the development environment with no problems, but when I build the executable file and run it I get error loading VI where Get Text Rect.vi, Error Code Database.vi and NI-FileType.lvlib. Thjis same file does run OK with no such errors when run on the other CentOS machine. I looked at /usr/local/natinst directory to see if the library file was there but I could not see anything different between the two machines. My next thought was to completely uninstall the LabVIEW PDS and reinstall it. Any other ideas on this problem?
  3. I have a MC Listbox with 8 rows and two columns with the text in each cell set with center justification instead of the left justify default. I had to adjust the text for each cell to achieve this; however, this was a bit of a pain. Now I need to expand to 96 rows with a vertical scroll bar and really need to set the justification on the cells in the MC LIstbox to that they are all center justified and need to do this programatically. I did not see any propertied in the MC Listbox that would help. Any suggestions?
  4. OK! I saw this option but never associated this unnamed VI being the result since I thought that the tutorial popup was being disabled... Thanks
  5. I have a LabVIEW 2009 Full Development Package running on a Linux machine and somehow i've configured the IDE to bring up a default VI when starting up the IDE! I've checked Tools -> Options but still do not see where to change this start up behaviour. Anybody know how to do this?

    TDMS

    I have Full Development System 2009 that I have been using along with a Windows version and just noticed that I do not seem to be able to use the TDMS library in the Linux version since it is not there! Are there any plans to add this in the near future?
  7. I'm using LabVIEW 2010 on a Linux Centos5.0 machine and find the installer target option is not available in the Linux version. Does anyone know if and when this option will be made in the future? There is already an rpm for the rte environment, so maybe being able to make and rpm of the project would be the way to go.
  8. Unfortunately, my customer has a case of featuritis. The legend lets him change width since when there are 6 plots he wants to verify where any one plot is as they may be overlapping one another. To make matters worse, I'm developing on a Linux version of LabVIEW full development system (v2010) and there is a little more restriction in available fonts and sizes on these machines.
  9. I have a screen with a chart that is displaying 6 parameters out of a possible 192 parameters. I moved the legend where I could set a vertical array of 6 integer controls for transmitter number, and another veritcal array for channel number, and yet another for parameter type all placed next to the chart legend with the intent of making rows of control corresponding to the legend rows. The parameter name in the legend is updated by value change events from the first two arrays depending on what the user selects in the transmitter and channel columns. All works OK, but I have one small problem: I really would like to be able to change the height of the legend so the the six parameter names would line up better with the elements of the vertical arrays located next to the legend box. It is good enough to use as is but I still would touch up the esthetics a little to line up these items up perfectly for the finished product. The numerical controls vertical size set to 20 bits and cannot fiddled with, only the width is adjustable which is of no use. Is it even possible to fiddle with the vertical size of the legend?
  10. I did some experimenting around and found the following things had to be done after using you separate loop/ msg queue idea. I had to make a custom VI that was neither modal or free floating since I wanted the minimize icon to be used. I also had to implement a 'Singleton' pattern idea even though I am not using OOP so that the button event to bring this up will only ever bring one VI up. Then I discovered that the 'look and feel' needed another fix up so that the button event would reopen the front panel via a property node when the event was generated and the VI was in minimized state. Works great! thanks for the pointer.
  11. That is an interesting suggestion! I will experiment with it this weekend. Silly me, I really just thought that the modal button was going to do all and completely forgot about handling the events........
  12. I have a project with a producer-consumer pattern where the producer queues msgs to the consumer via an event structure and a msg queue. The consumer is also a FSM (state machine). I need to add a non-modal dialog box to the GUI so that I can recognize the events from the main GUI as well as the non-modal dialog box. I already have added modal dialog boxes which run OK, but, since they are modal, only the dialog box will receive events until I close the box. I also need to have the ability to hide or minimize the box while I work with the main GUI since I plan on this dialog box showing a list of items that the user will need to see while using the main GUI. If I bring up the non-modal dialog box in the producer event structure, I'll lock out all other events. If I do this in the consumer I'll run into other problems with the existing GUI. What I think I have to do is try to run this in another thread initiated from the event structure, but I have not yet figured out how to do this. I would love to hear some ideas on this one... In the meanwhile I'll be experimenting and checking the examples for more insight.
  13. [i did not realize that there was a RespToOutLimits.Max property! I did find the Max and Min properties, but without coercing that control didn't work as I wanted. So many properties, so little time. Thanks
  14. I did not see a property for min or max. I did find value, which should be spelled in the plural to eliminate confusion, and used that property in a for loop to changed the out of limit values dynamically.
  15. I have an array[6] of controls (SGL data type) and need to reassign the 'max value' of all 6 elements so that the user cannot exceed this value. Normally I would set the 'max value' in the data entry box and be done with it, but this has to be reassigned dynamically once the user has determined this value on the fly. I cannot think of any other way to do this except to use a 'value change?' event to compare the entered value to the present desired 'max value' and force the display to adjust the displayed value as necessary. Anyone have a simpler way to do this?
