      Hello, I'm trying to display an animated GIF on the front panel. This gif should be loaded programmatically based on some user event. My google search led me to use the OpenG Read GIF File (Animated)__ogtk.vi file. However, loading a GIF is extremely slow. It takes almost 20 seconds to execute the vi when I load the attached GIF (I found randomly on the internet). Is this normal? And if so, is there a way to load a gif faster? Because I need to load several and I cannot afford to load maybe 2 minutes only for the gifs.

      Hi all,
       
      I've got a customer that wants to zip/unzip files on their cRIO-9035, so I had them playing with the OpenG Zip tools to see if it would fit their needs. Although they've found that they can zip files on their cRIO just fine, they find that they get disconnected from their RT target and the shell shows the following error message:
      LabVIEW caught a fatal signal 15.0 - Recieved SIGSEGV Reason: address not mapped to object Attempt to reference address: 0x0x10000000 stdin: is not a tty  
      The zip file they're testing with includes two simple .txt files with short strings in them ("booya" and "booya2"). This file unzips just fine on the host PC with the "ZLIB Extract All Files To Dir" VI, but when copied over to the cRIO and unzipped via the same VI, it only unzips the first text file and the resulting file doesn't have any text in it.
      I've attached a copy of the project and the zip file I used to reproduce this behavior using a cRIO-9033 that I had on hand. (The only thing I can't provide is the cRIO >_<)
      Could anybody tell me what I'm doing wrong? Any suggestions as to what other workarounds I could take to zip/unzip files on a LinuxRT target would also be very much appreciated!

      Hello to all.
      I have an application wich use; imaqdx (displays...), sliders, many controls and many indicators, and everything in a tab control of 3 pages and 2 subVI.
      I am trying to use "write and read panel to/from ini . vi".
      The first thing that my program does is to read panel from ini.
      Here there is the first problem because it gives the next error: "Error 91 "The data type of the variant is not compatible with the data type wired to the type input. Set control value"
      Here is my piece of code in image attached (boolean input in open.vi is True).
      I notticed that it gives me an error if the .ini file does not exist (but it should work even .ini file does not exist).
      Well, my next step was to create a .ini file before to use "read panel from INI.vi".
      So I use "write panel from INI.vi" and it works fine. It does not give me any error. and the ini file is the next:

      Well, next step is to read this .ini file and now it does not give me any error but it stacks in "read panel from ini.vi" (maybe it takes about minutes for reading .ini).
      How can I do to write and read panel to/from ini well?
      It is very important for my application. Maybe there is another library that I can use?
      Thanks a lot!

      Good morning,
      I have a DLL I created (in Labview)  that takes in string information, does some magic crunching on it to create a password that is passed out as a string.  This DLL will be called from CVI and probably from a C# application.
      This should be so simple, however I cannot figure out how to pass the string in and get the modified string out of my DLL.
      I've had no luck at all getting this DLL to work by trying many different things.  It crashes LV, returns and error, or simply passes nothing out during my trials.
      I've included the project (its small) in zipped format.  Can one of you kind souls take a look at my code and tell me what I'm doing wrong, or what I need to do correctly to both, configure the DLL and then call it from LabVIEW?
       
      Thank you!

      Hi.
      Im working on this prosjekt where I have a TCP communication between two computers (Server & Klient). I have managed to get communication between those two. (Sending and reciving one cluster.) But I want to send and recive more than one. I looked at det Topic "Passing Cluster and Datatype Through TCP" on how to use the OpenG, but I have a problem with "the Variant to Data". 
      What am I doing wrong? Or is there another way to send more data?
       
      The Klient side:


       
       
       
      The Server side:
