Opening Word, Excel and PowerPoint Files in LabVIEW with Digital Signing of Files

[Al.abd]

Hi there,

I am looking to open Word, Excel, and PowerPoint documents in LabVIEW (or have then converted to a format that can be opened). After opening, to complete some checklists and then insert a pre-set digital signature (possibly through a username and password authorization) and save the file while preventing further  editing or print a pdf report of it.

I have a good experience with LabVIEW but not in this sort of a system.

I appreciate if somebody can point me the direction to start.

Many thanks,

Al

Hello Al,

So it's somewhat three different things here: 1) importing Microsoft documents 2) run 'checklists' (can you expand on this?) and 3) insert digital signal/password authorization, then print report.

1) Usually we use Active X containers or Report Generation toolkit to import these, Excel example, Active X example

2) please expand more on desired functionality

3) Are you looking to make this into an executable? Might something along the lines of aPFX certificate work? If so, LabVIEW requires a pfx certificate for digital signing.

Regards,

Deborah Y.

Hi Deborah,

Thanks for the reply and sorry for being late to reply.

1: I want to be able to at least view the content of the MS document, which will have complex formatting and pictures included.

2: Simple check boxes and diagrams, as in a form; you see a check box, some instructions, a picture, and you simply change the box to checked status.

3: Yes, I am looking to make it an exe. Relative to this, is there a way for me to create user names and passwords for user that will use the exe?

Thanks for helping,

Al

As for (1): there is no ActiveX control to view Microsoft Word/Excel/PowerPoint files. If you want to view these on a LabVIEW front panel, then the easiest solution is to use a web browser control on the front panel. This will allow you to provide the path to the file as the navigation URL for the web browser control, and the file will be embedded in the browser control. It would be no different than viewing it inside of Internet Explorer.

As for (2): Assuming you view the document on the front panel, this sounds like basic LabVIEW programming, so I'm not sure what you're asking for here, or what you're having trouble with.

As for (3): I have to admit I'm not totally clear on what's being signed. It also sounds like the signature and the PDF printing are two separate objectives here.
