I need to find out what version of Xojo was used to create a Web App.Is it possible?

Thanks,
Larry Vatland

Not unless you bake something into the code that will show you the XojoVersionString.

Edit: Your use of past tense suggests that you’re working retroactively and only have the build. If the build was compressed in a way that retained the original file modification dates, we can try to make some inferences.

Tim, Thanks.

I have a build that has ran very well and need to find what version it was built with. I’ll check into the dates and see if I can make any sense out of them. It maybe wouldn’t be a bad option for Xojo to implement?

You could compare the sizes of the Xojo runtime libraries to see which one matches to one coming with the Xojo IDE.

Sizes vary over time.

You could create a Feature Request ticket to ask them to consider the idea.

You could also make a sha1 hash of the libraries.
