Open executable [.exe] vi at windows with specific file

[Zbigniew StS]

Hello!

I would like to know how to open executable vi, made with Application
Builder, at windows [Win 2000] if I have file with specific extension [let's
say ].
I have seen some article at NI Developer Zone but I cat find that now.

regards

There is an article on how to do handle custom file types here: http://openg.org/tiki/tiki-index.php?page=File+Handling+Guidelines

This method makes use of a VBScript to invoke a LabVIEW ActiveX server. It will work with a build LabVIEW App if you enable the App's ActiveX server in the build file.

Good luck,

-Jim

Hi,

You have to assosiate the file extension to the application. This can be
done in windows explorer (and perhaps through the registry, somehow).

If the executable opens, you have to get the command line to see if a file
was used to open the application. This is the hard part.

Regards,

Wiebe.

Yes you can get the command-line args, but this only works when first launching the application. It will not work if the application is already running. For this, you need to message into the running application using some other mechanism. Most apps use DDE for this.

Here is a utility that will allow you to get the command-line arguments using a WinAPI call:

Also, if you are using LabVIEW 7.0 you can get the command-line arg's using the VI Server property "App::Command Line Arguments".

Yes, right. I've thought about this situations:
1. I have vi application in "exe format"
2. I would like open and run this application by clicking on the specific
file with user-defined extension. File consist data for "exe-application"

I've seen article at Dev. Zone: rules about develop the Vi and specific
records in windows registers.
