Regarding Lianja, it's hard to opine about something that doesn't exist and has no track record.

Your requirements that you use existing code and run on all platforms preclude everything that is currently available so your choices are:
-do nothing and hope that something comes along to meet your requirements.
-change your requirements


>Hi All,

>We are running a software company and have a complex database app in the medical field. Since VFP has been discontinued we are searching for another development tool that can move us to the next level. By that I mean:
>
>- A more modern user interface
>- Running cross platform or at least some tablets natively
>- A solution to upgrade our application to run in a browser.
>
>This of course without having to rewrite all our code or entirely redesigning (we are using a lot of VFP scripts stored in the database, out there on many clients) the application.
>
>We have found that at least from a functionality POV Lianja seems to fit us best. Granted, it has not been released yet, but so far the comments I've read are positive. The company behind it seems to be a solid company (as opposed to the ones we have seen in the past) and their functionality is certainly looking impressive.

>Since it is supporting VFP compatibility to a high degree, it seems very interesting as much code could be ported over without much problems (I'd assume) and we do not have to entirely retrain all programmers into a new programming language. The support for other language like Python, PHP and Javascript as a real bonus I think.

>If this works, we are willing to invest in this product. the pricing seems reasonable to me.

>My question is what your opinion is about Lianja. Are there any caveats we should know about. Are there any valid reasons not to go this way ?
