windows explorer doesn't open LLB files.

[Anonymous]

was running LV6, 6.1, now 7.0 on win98 machine.
recently ran microsoft regclean and now I have no more support for
viewing inside .LLB files through windows explorer. Attempting to
re-enable this through LabVIEW/tools/options does not help.
Any hints?
thanks

Paul,
In LabVIEW 7.0 on Windows, you can enable Windows Explorer support for .llb files so double-clicking an .llb file displays the contents of the library. You can open, move, copy, rename, and delete files in the library. Refer to the LabVIEW 7.0 Upgrade Notes (linked below) for more information about enabling Windows Explorer support for .llb files. You also can access the LabVIEW 7.0 Upgrade Notes in LabVIEW by selecting Help»Search the LabVIEW Bookshelf.

Paul,

It could be a missing reg key that is causing this problem. I had a similar problem where viewing LLB's didnt work after a program installation. I solved this by reinstalling or repairing LabVIEW. This should work for you also.

P.S One thing to check in your windows File Types option that LabVIEW is set to open LLBs. I have attached screenshots of the settings.

Zvezdana;
That's the whole point. I cannot enable this function. If I could
enable it, I could use it. It does not enable.
Actually, I've made the situation a bit worse by tinkering with it
(file associations) and now the tools/options/LLB enable box is grayed out.
I was hoping that I could put this back in working order without
reloading LabVIEW.

I cannot offer answers but I can offer support. This function is broken on the two Windows XP machines that I have tried it on. On one machine if I check "Enable windows explorer for LLB files" then whenever I double-click on an LLB file all I get is the LV splash screen followed by the New/Open/Configure/Help box. From there I can open the LLB. If I remove the check in the "Enable windows explorer for LLB files" box (& reboot) then the LLB will open like it used to in v6.1.

On the second machine if I check "Enable windows explorer for LLB files" then whenever I double-click on an LLB file the CPU usage goes to 100% for a bit more than 3 minutes (the machine is almost totally useless during this time) and finally an explorer window will open showing the con
tents of the library (& the CPU usage drops back to normal). If I remove the check in the "Enable windows explorer for LLB files" box (& reboot) then the LLB will open like it used to in v6.1.

This is clearly a function that is not yet ready for prime time.

It appears that running regclean has busted this function by
removing 7 entries from the system registry.
Running ADD/REMOVE PROGRAMS/National Instruments/LabVIEW/repair,
repaired the problem, and returned Windows Explorer support for LLB
files, unfortunately it also removes the LabVIEW registration name and
Ser#, but this can be easily found (and repaired) in ...
HKEY_LOCAL_MACHINE
SOFTWARE
NATIONAL INSTRUMENTS
LABVIEW
7.0
in the system registry and values typed in for Registered Owner & Serial
Number fixes the 'unregistered' on the splash screen.

back to the LLB Explorer support problem,
What I actually did was to,
1) run regclean to make sure there wasn't any crap in the registry.
2) fix the LLB Explorer support
problem by 'repairing' LabVIEW from the
ADD/REMOVE PROGRAMS system function.
3) run regclean
4) rename the 'UNDOwhatever.REG' file (in regclean directory) to 'Fix
LabVIEW LLB Support.reg'
5) Finally, double click 'Fix LabVIEW LLB Support.reg' to put the data
back into the system registry.
In this way, if I ever run regclean again and it removes the LLB
file support in Windows Explorer, all I have to do is run 'Fix LabVIEW
LLB Support.reg' instead of repairing (re-installing) LabVIEW.
I did this in on a Windows 98 system with LabVIEW 7.0. Your milage may
vary with other platforms or applications.
