app version problem

[Tushar_Jambhekar]

When i build executable from my labview code, i expect that

1. App.Name should return the name of my built application. (This is working as expected)

2. App.Version should return the Version of my Application (this property instead returns LabVIEW Version)

Please find attached example where app. version is 2.0.0 whereas labview returns 8.2.1

If this is what, NI Itends to give, then is there any alternative way through which i can get the version. no of my application?

Hi, Tushar,

There are different possible ways to do this. You can do this with .NET (FileVersionInfo.GetVersionInfo), or with WinAPI (GetFileVersionInfo()).

In attachment you can found the example, which returned proper version of the application.

Best regards,

Andrey.

Problem confirmed in LV 8.5 also.

Maybe you can file a bug report with NI.

Andrey,

But it [Application property - Version Number] does not serve its intended purpose...

And that means a bug, which NI needs to look into, right... ?!

Partha,

This is the question - "Is this "Bug" or "Feature"?

Right now App.Version return the version of LabVIEW Run-Time Engine. So, you have at least two versions - one is Application, and another one - RunTime. So, may be in the next version this behaviour will be clearly documented and the problem will be "solved".

But I agree with you, that its will be very convinient to get Version of the Application with native LabVIEW property node instead of playing with WinAPI or .NET or other tricks.

If you ask NI it's a "feature". If you ask everybody else, it's a "bug".

I just use a global variable that is a string with the default value set to the version number. You can also use a simple VI that outputs a string from a block diagram string constant that's the version number. Simply, admittedly kludgey, but it works every time.

Thanks for the information everyone.  This was reported to R&D (# 4G27K2P2) for further investigation.  The workarounds mentioned above are great suggestions.  If you are looking for more information, there are KnowledgeBase articles on how to use .NET or Windows API calls to determine the version of an executable.
