[RESOLVED] Develop VB6 Application On Vista for WinXP

[barianto]

Hi All,

I planned to develop VB6 application on Vista Home Premium, since i read it in this forum that can be done.
This application will be run on Windows XP or Vista.

Please give me advice what should i do or shouldn't.

Thank you

As far as I am aware, nothing. The problems arise when programmers do things XP allows but Vista doesn't. If Vista allows it, I'd say you're golden.

I could be wrong, though, never having used Vista.

Well it depends on what your program is going to be doing and accessing. If you are developing a VB 6 app under vista and using any of Vista only features then when you run it on XP it will crash or error.

I think i got the message, i will try to avoid "vista only feature".
I'm searching on VBFORUM and can't find anything about "vista only feature" (related with VB of course) and googling on it made me lost.
Do you guys can show me link on this forum or on the net about this matter?

Thank you guys

If you are using any Windows features in your app then there is a chance you may be using something specific to Vista. There is no exact list of what is a Vista feature or not. Things in Vista like Windows Presentation foundation for example would be a Vista only feature but if you dont know or use this then that should not be a problem on XP.

We can not tell you what to use or not use as we have no idea what code you are writting or what your app does.

Thanks RobDog888

What about with "API"? is it still okay for me to use it?

[Merri]

You can use API as long as you check you're not using Vista only features. This should be pretty easy to find out, most stuff you find on the web is pre-Vista anyway so it is unlikely for you to even bounce on API related VB6 code that is Vista only.

good point,

still wishing there is list which is vista only feature or not, but i think in the next hour i will tickmark this thread as resolved.

Thankyou all guys.

Most of the changes are so small that it is cumbersome to list them. For example, Vista allows you to draw shadows and other decorations to your text when using DrawText API. Having the related values passed in XP has no effect and the application doesn't crash, you just don't get the effects you'd get on Vista.

Now imagine there are thousands of this kind of small additions. Basically most of these problems can be silently ignored with a proper error case handling and investigation from MSDN for features on the used API call. Thus there is no point for making a collected list for Vista only features to be aware of, especially listing them for VB6 as Microsoft gives no support for it anymore. With API, MSDN and Google is always the quickest way to find something out as MSDN clearly states what is supported starting from which version of Windows.
