call pdf from LV

[didierj]

Hi,

The Task I'd like to perform seems quite easy, but I didn't manage to do resolve it at whish:

- providing just the path and filename of the pdf-file to system exec.vi, hoping that Win calls acrobat, doesn't work.

- providing the path and filename together with a "call" opens an unwanted command-line window, but works.

Does anyone has any idea how to open a pdf-file with the standard-application that is installed on the computer (in other word: let Win resolve the app that is linked to ".pdf")?

It should work on Win98 to WinXP, the pdf-viewer might (but must not) be acrobat reader, where the pdf-viewer is installed is unknown, if it is acrobat in which version it comes is unknown (so activeX is also not an option). Additional command-line windows are unwanted. LV version 6.1.

Hi Didier

In the LV forum was a discussion about

system exec.

Maybe this helps you.

Thanks, it helped.

I wasn't aware that I had to provide also a title to start-command, since the pdf-file I use has spaces and have to add " before/after the name. Thus <start> interpreted my input just as window-title, missed the command and returned with a "memory-full error".

There is a VI to do this in OpenG using Windows Internet Explorer.

www.OpenG.org

Be warned calling a PDF can be quirky. I've had it successfully work on my development machine everytime.

But then on installed applications - it will NOT work the first time?! (Windows)

I was using this for on-line manuals and help. But ended up taking it out in most distributed applications.

I found this on the web some time ago (I don't remember where). I hope it helps.

There ist a VI already in the vi.lib.

-> "Open a Document on Disk.vi"

Can be found here: ...\LabVIEW 7.1\vi.lib\platform\browser.llb

Could be wrong, but if I recall correctly, that VI is password protected without insght into how to actually perform the call.

I found no password protection in these VIs.

Cool. :thumbup: I think I found that VI somewhere (maybe a previous version?) where it was passworded or something where I couldn't look at the block diagram... you're right on though... essentially the same thing as the previously posted VI with a little more subvi structure.

I just append an improved version of the _browser WREG Read Key.vi here that is used by above mentioned Open Document on Disk.vi. I'm almost certain I had put that up somewhere already but may not remember right, so I do it now here.

This VI takes into account extra registration of applciations for a certain file type and treats them the same way explorer does. The old way opened the last registered application for that file type.

It is LabVIEW 7.1 format and the latest LabVIEW version might already contain this improvement, I didn't yet check.

It works with _System Exec.vi_ provided you set the command to

cmd \c "path\to\any\doc.type"

Set Run Minimized to True.
