  1. Hi, I'm facing this issue with LabVIEW 2014. I have made a program with LV 2012 that passes some clusters to another application, made with LabVIEW 2012 also. All clusters are passed as strings between the two programs, using "Flatten to String" and "Unflatten From String" VIs. Well, everything works smooth when both applications are compiled with the same release of LabVIEW. I have rebuilt the application that send data with LabVIEW 2014 and the receiver generates an error because cluster version is not recognized Is there a way to preserve cluster version (i.e. maintain LabVIEW 2012 version, in my case) so that I do not need to rebuild all applications with LabVIEW 2014?
  2. Hi, the code of both VIs is exactly the same, and button is placed at panel origin, so, error is not due to button position. in addition the code is independent from splitters and panes. The very strange thing is that both VIs are identical, but they calculate a different value of Y (i.e. Vertical distance from top of the screen). I attached the VIs saved for LabVIEW 2011. I also noted that the file sizes are different, but I don't know the reason. CORRECT RESULT.vi WRONG RESULT.vi
  3. Hi, I didn't know how to entitle this topic. I hope this title is not too generic.. I have attached two VIs with the same code. Purpose of the code is "calculate the position of the upper left corner of a button, in display coordinates, not panel coordinates". When I created the code, see CORRECT RESULT.vi, it worked fine. Then I copied the code into other VIs and the calculated result is not correct, see WRONG RESULT.vi (I have highlighted the wrong value with red backgrond) I have checked the VI properties, but I haven't found a specific property that solve the issue. My colleagues discovered this odd behaviour because they placed the function in existing panels (some of them have complex interfaces with mutiple panes and splitters and in some cases it works, in other cases doesn't work. Have you seen something similar in past? CORRECT RESULT.vi WRONG RESULT.vi
  4. Thanks guys, creating a small app with a splash page that loads dynamically the main application is not feasible in my case so I was wondering if there is somewhere the opportunity to set the "timeout" that controls the visualization of "Loading" dialog. In any case, you have to be agree with me that the idea of a fixed timeout after that a "loading" dialog is displayed is somehow odd and typical of LabVIEW. I have never seen something like that in programs made in other programming languages.
  5. My application loads VIs saved in some packed libraries. It doesn't load dll, apart from lvanlys.dll which is in the same directory of executable file. In my opinion, if LV searches for them, I understand that it can take a while to start the execution. I wonder if that window could be optional, so that final user doesn't see the loading process.
  6. Hi, I have some applications (executables) made by several VIs and when they start, users see "loading in progress" window which displays VI's names. This is a typical behavior of LabVIEW, that other languages don't have. Is there a setting to hide/disable that window? Thanks, Claudio
  7. Well, from my point of you, it's easier creating multiple .ctl files with customized buttons and load them when necessary. My question is: how can I load a button into a panel, programmatically? usually I add buttons when I edit my panels and I was sure it's not possible to add buttons to a panel at run-time...
  8. Thank you guys, I think that changing the image attached as "decal" is enough in my case. Usually, I customize buttons and I was wondering if it possible to do it programmatically in an executable file (without scripting). I have seen that it's possible to import multiple images from clipboard as "decal" when I customize a button. Is it possible to switch between imported images, programmatically (using a "decal index" or similar)?
  9. Hi guys, I have would like to replace a button in my panels according to user choice. My idea is to create two skins for my application and I have found that to provide a nice user experience I have to customize LV buttons. I've saved two .ctl files into two libraries. Controls have the same name. I tryed to replace the first packed library with the second one, before launching the exe, but button on front panel doesn't reflect the change. Have you any idea? is it feasible?
  10. Hallo, I have done some manteinance to an application compiled with LabVIEW 2012. That app has an installer, so my users can upgrade it easily. I usually install the application on the same machine where I develop with LabVIEW and after I try the installation procedure on a clean machine to see if issues arise. Today have seen that on the development PC, the executable runs fine. Instead on the clean machine, the following message appears after that the application has loaded the panel. Have you seen this message in past? I have found some posts here: other users have found the same issues, with older versions of LabVIEW. forums.ni.com/t5/LabVIEW/VI-has-an-error-of-type-2208-42308-302208/td-p/1540496 I have upgraded the DAQmx drivers on the clean machine , but the issue remains. Any idea?
  11. Hi Neil, I added the three lines to the .ini file , listed below, but the issue remains. server.app.propertiesEnabled=True server.ole.enabled=True server.tcp.paranoid=True server.tcp.serviceName="My Computer/VI Server" server.vi.callsEnabled=True server.vi.propertiesEnabled=True WebServer.TcpAccess="c+*" WebServer.ViAccess="+*" DebugServerEnabled=False DebugServerWaitOnLaunch=False appFont = "0" 13 dialogFont = "2" 13 systemFont = "1" 13 I wonder: if the VI loads a different font, which is that font name? With the font name, I can search it into the LV project...
  12. Hi folks, I have created an executable with LV 2011 and I have found an unexpected behaviour of my application: the VI's menu uses an unreadable font or charset. When I run the same VI from LabVIEW (i.e. the source code), I see the standard LabVIEW menu. Above you see the screenshot of panel executed from LabVIEW IDE, below you see the same VI executed in my .exe app. browsing submenus I see the strange font in every submenu. Instead, labels and captions on panel have standard font. In past, I have built other applications on the same machine, all worked fine. Have you any idea? are there special settings in build spec.? Claudio
  13. I've disabled file indexing and virus protection: nothing is changed. At this point, I wait for LV2012: perhaps it performs better on 64-bit OS. thanks to everybody for your patience !!
