I still have no way how to deal with the LabView Data folder automatically created in the My Documents folder whenever I run the application

Question

I tried numerous ways that some people suggested in this forum but did not succeed in having the LabView Data folder created somewhere else than in My Documents when running a built LabView application. Changing the target destination folder did not help at all. A member suggested to put some line like " defaultdestination = ..." or so into the build file, but I did not know where exactly to put such a line. That folder created is particularly anoying for people who don't normally use LabView but are only using the application. Please let me know when you LabView Experts out there have found a way to eliminate or relocate the creation of that folder at application startup.
Thanks a lot.

Tim,
use the path constant located in the Functions pallette under 'File I/O->File Constants->Default Data Directory'. It refers either to the default directory (which is (osdatadir)\Labview Data on my WinXP system) OR TO A NON DEFAULT PATH if you have defined one. To define a non-default path, got to the menu 'Tools->Options...' and change the entry under 'Paths->Default Data Directory'. This change will create an entry in the labview.ini file (located where the labview.exe is), e.g. the entry 'DefaultDataFileLocation=d:\temp' is created when I change the default data dir to 'D:\temp'.
Now for a compiled .exe with the name (say) myapp.exe you will find a file myapp.ini in the same location where myapp.exe is. It is usually an emtpy file directly after the application build process. Put the line 'DefaultDataFileLocation=(your path)' in this file.
Users of your compiled app can either
- edit this .ini file to change the default,
- or you can make the menu entry 'Tools->Options...' accessible in the built VI
- or you can provide a self written dialog in your app and modify the myapp.ini programmatically
(This last way is probably not a good one since the user might have to relaunch myapp.exe in order to affect a change of the 'Default Data Directory' path constant)
