Incudes an example that shares data between two vi's.  Compiled for 32 bit.  Source included so dll can be modified and recompiled for 32 or 64bit.  Used the Labivew .dll import wizard to automatically create vi's if you recompile the dll.  (Select the LabviewSharedMemory.h as the header file.)

Hi,

I noticed that the Call Library Function has the option "Thead" in the Function-tab configured as "Run in UI thread". I'm using this library in a time critical part of the code and I want to avoid issues caused by the Root Loop (More info: https://www.winemantech.com/blog/the-ui-thread-root-loop-and-labview-what-you-need-to-know/  or http://www.labviewcraftsmen.com/blog/the-root-loop)

Is this DLL thread safe and therefor possible to configure the Call Library Function to use the option "Run in any thread" ?

Thanks

Thanks in advance!.
