VB4 to Black Berry

Can someone tell me the steps to go through to get a program that I wrote in VB4 for the PC to now be an app for a Black Berry cell phone or any other type of cell phone that is capable of running programs?

Thanks. We'll let you know when a new response is added.

iPhone = Objective C
Android = Java (kinda)
BlackBerry = Java (kinda)

Alas, there is no way to get a VB4 program to run on any of those platforms. It’s not even compiled for the same processor architecture. The only way I can see you get a program you wrote in VB4 onto one of them is to directly rewrite it in one of those languages I listed above. But, VB4 is so foreign to those languages that you may have a major struggle to make it work.

I started with VB4, so it holds a special place in my heart…but…I can’t imagine porting anything I wrote in it to a modern phone at all. You’d need to be at about the same level of expertise in both languages in order to convert the whole program methodology like that.

Sorry! (But, hey…if you know Java…go ahead and try rewriting your logic! If not, I’m just afraid you’d be facing what may seem to be an insurmountable challenge.)

    Thanks for this knowledge. I knew it had to be in a different language, but thought there might me a program to do the swapping, but I guess not or at least not at a worthwhile price. Thanks again.

    I agree with Koohiisan. That won't be an easy task. You are most likely going to need to rewrite the application. As mentioned above, if you know Java, some of your options would be Android, Black Berry and Nokia (Symbian). If you know C, it wouldn't be too hard to learn what would be needed to port it to iPhone or Nokia (symbian, maemo, meego). Maybe the easiest path would be to port it to Windows Phone. I don't know much details about that platform, but I would assume some level of similarity between VB and the Visual Studio edition used for WP development, as both tools come from Microsoft. Good luck.

    Good point about Windows Phone, Carlosdl! I hadn't thought of that. I suppose then your best option in that path would be to head to the Microsoft VB Developer Center and begin familiarizing yourself with VB.net using their free Express version. A lot has changed since VB4--especially going to .net. But, at least the syntax should be similar enough for you to get started. It'll still be a rewrite, though. Happy coding! :)

    hi Koohiisan, Thanks for your efforts, I know a lot has changed since VB4, but I have my personal reasons for using VB4 and that is a bit of a story, so won't go into that now, I have tried other languages too, but I always find myself going back to VB4. lol I’ve done some C, C+ coding among others but found that so far I’ve been able to get er done best in VB4, I’ve tried VB6 and VB2500 I think it was, ML. And probably a few other languages never mastered any but for reasons I again won’t get into here, end up going back to what I like. VB4.

    @TheFinder I wasn't trying to dissuade you from your use of VB4 (sorry if I came across that way). I just meant that you could get into VB.net if you wanted to rewrite the VB4 program for Windows Phone. (They have a phone SDK for VB.net and it would be more similar than the other .net languages.) You could also look into contracting out someone who is familiar with those languages in order to get your program onto a phone. Just a thought.
