Read-only error for .mnu files when trying to edit function palette

[mdees]

I am trying to modify the functions palette to include some custom VIs in user.lib or vi.lib/addons (I can't get either to work). I am trying to create several layers of palettes in different groupings, etc, so I am creating .mnu files for each sub-menu.

The .mnu file creates OK and sometimes I can modify it with no problems. In some instances, though, I get an error that says it cannot write to the .mnu file because it may be read-only. This happens more often than not. I have checked the file attributes and it is NOT read-only. Once I get into this mode, the .mnu file cannot be modified further.

Is there a different or better way to create/modify .mnu files?

There's a function in LabVIEW (at least in 5.0) in edit>>edit function and controll palettes that will do what you want.
Hope this helps

check for a file called READONLY.TXT this one hinders editing a menu directory.
Just change the name to _readonly.txt and don't forget to change it back when done if you don't want others to mess with the menu files

A couple of things: are you using a custom palette? Or are you trying to modify the default palette? Try creating your own palette based on the default palette. The custom ones are much easier to modify. I ran into this myself a while ago and the seperate menus were editable the FIRST time, but not after that.
Also: you can change the name of a file (mine are all in .dll's) and then it can be edited (once).
I worked with NI's support on this one and never did get a real fix. I just use the "copy/name change" work around.

The Solution to this problem (in LabView 6 at least) is to ensure that the 'Synchronize With Directory' menu option is un-ticked for any submenus where you have edited the contents of the submenu, before attempting to 'save changes'

Right click over the submenu's icon to get at this menu option.

I don't know what effect this menu option is supposed to have - but it seems to do the trick!

In LabVIEW 6.0.2 you cannot uncheck 'Synchronize with Directory' when the VIs are in a LLB since this entry is grayed. This item is checked by default.
I created a new LLB and want to change the palette for this LLB because all VIs are in the palette and not only the top level VIs. I do this in the standard palette. Since this LLB will be distributed with a hardware product the LLB will be installed in the user.lib folder and the application programmer should have the LLB available in the functions palette without doing enything else.
