Click here for more help

[ggwilli]

I'm running LV7 under Linux. With Context Help running if I mouse over some native LV VIs I get an option in the Context Help of "Click here for more help". When I do so the Context Help simply loads the help for the Add VI. I had this problem with LV6.1 and assumed it was a version bug. Upon upgrading to 7 the bug remains. I've seen some discussion about this under Windows platform but no solution for Linux.

Hello Ggwilli,

I think what you are seeing is not the help for the Add VI but the default image of the context help window. What seems to happen is that after clicking "Click here for more help," the context window becomes unlocked and goes back to default. When the online help is open,however, there is no need to read the context help. It should be in the background and it doesn't hurt anything.

Just to make sure I understand the situation, can you please answer these questions?

• When you click the blue "Click here for more help" link, does the Web browser appear? If not, what happens?
• If the browser does appear, do you see the Add topic in the right pane and a table of contents in the left pane? Or do you see only the Add topic in the browser window?

Also, which browser are you using?

This information should help us isolate the problem.

Thank you,

When I click the blue "Click here for more help" link no browser opens,
rather the "Add" context help appears in the existing context help
window as if I'd just moused over an Add vi.

I'm using the Mozilla browser.

I believe you're correct about the "default image" of the context help window appearing. However, the online help never appears and that is my problem. If it appeared I wouldn't care what the context help window was doing.

When you click, LabVIEW tries to launch a browser and display the help there. LabVIEW requires a recent version of netscape/mozilla in order to do this.

Try running the command "netscape" on the command line, and make sure it runs. If that doesn't work, you'll need to fix netscape.

I just posted a comment above before I read you are using Mozilla.

In general, "netscape" is the command that we use, but here are some more specific instructions:

(1) Open the VI "Get Web Browser Path.vi" in /vi.lib/Platform/browser.llb, and run it.
(2) Now type the browser command it generated into a console window and be sure it works.

Netscape and Mozilla are both available and work fine. However, your clue allowed me to solve the problem. It turns out I had /usr/bin/netscape in the file ~/.lvbrowser and netscape was actually installed in /usr/local/bin/netscape. I changed the file ~/.lvbrowser to include only the line /usr/bin/mozilla and it now works. I tracked down the .lvbrowser file by stepping through the subvis for "Open URL in Default Browser.vi".

Thanks for all the ideas.
