Blast from the Past: Delphi may be the only choice you have

Yet Another Blast  from the Past, this one from November 23, 2003.  This one is kind of moot now, as well, eh?

As frustrating as it is to us Delphi lovers, Delphi has always been a tough sell in corporate America -- not because Delphi isn't perfectly capable of performing any task that a corporate development team might throw at it, but mainly because many managers and decision makers aren't willing to take the perceived risk of investing in a non-Microsoft development solution. Borland has (rightly perhaps for a while in the past, but certainly not for a few years now) the reputation as being a bit on the edge financially, and so the safe, "nobody ever got fired..." decision has been to buy Microsoft. This will probably continue to be the case for some time, as Microsoft certainly will continue to be the a dominant company in the marketplace for the foreseeable future. However, I think the advent of the .Net Framework as the "platform of the future" and Microsoft's particular strategy for moving people to .Net both provide Borland and Delphi developers with a unique opportunity that actually makes Delphi the only safe development platform for a large number of projects that will be developed over the next few years.

Microsoft clearly wants us all to move to .Net, and frankly, I think we all should be happy to make that move. The .Net platform is really cool and really powerful. It provides a very capable and easily accessed framework (the Framework Class Library, or FCL) that is light-years ahead of the Win32 API. Microsoft actually seems to have finally figured out object-oriented programming. Once the actual framework becomes ubiquitous, or even the basis for the operating system itself , building, managing, and deploying applications will be much easier than it is now. I, for one, am eagerly looking forward to Delphi 8 for the .Net Framework and being able to develop applications with it.

Microsoft clearly wants you to move to the platform as well. They make it totally easy to download and install; every new operating system includes it, and they are on an all-out marketing campaign to raise awareness in the developer community in order to promote its use among software developers. The most interesting thing about all of their actions, though, is that they clearly want to force people to make the jump to .Net by pretty much cutting off existing development paths and by not providing a clear migration path for existing applications. It appears that the idea is to instill a bit of panic in their community of developers -- "Holy cow, we'd better get on this .Net bandwagon, or we are going to be left behind!"

Sadly, that is pretty much the case -- VB and C++ developers who don't migrate to .Net soon will be (are?) pretty much abandoned. Sure, there's "Managed C++", but what serious C++ developer would really want to use this neutered version of the language? VB6 developers are abandoned in the sense that VB.NET is so different from what they have done that it is pretty much a whole new language. Code written for VB6 simply won't compile in .Net. And of course, there were no existing C# projects before .Net was released. Therefore, if you are a Microsoft development shop, and you want to move to .Net, then you are pretty much talking about a complete rewrite of all of your Win32 code no matter what you were using to develop those applications. There simply is no easy migration path to .Net for your existing applications.

And that, of course, begs the question -- "What to do for a new application that needs to run on Win32 today, but that will eventually migrate to .Net sometime in the future?" This isn't an unreasonable question -- shoot, it is probably very common. There are certainly new development projects being started everyday, and .Net looms out on the horizon for all of them. It is also a question that is tough for Microsoft shops to answer. While the .Net Framework is readily available, it is certainly not ubiquitous, and there are plenty of machines out there in the corporate world, small businesses, and homes that can't even handle the .Net Framework and that won't be able to handle it for sometime yet. That means that Win32 may be the only option for new development. However, anyone starting new development today probably will want to be able to migrate that app to the .Net platform in the future. If you choose C++ or VB6 for the Win32 version, there simply is no easy way to migrate that application to .Net. Any Microsoft-based development solution for the Win32 platform today means pretty much a complete re-write for that application when it comes time to migrate it to .Net.

But hey, there is a solution -- a non-Microsoft one -- to this problem: Delphi. Delphi provides a powerful, fully-capable Win32 development platform, and with the VCL for .Net, a much, much smoother migration path for Win32 to .Net. And when you do move to .Net, Delphi 8 for the .Net Framework provides powerful tool that is a first class citizen in the .Net development world. If you are starting a new development project in Win32, and need to be able to move that project to the .Net framework some time in the future, then Delphi is your only real choice. Microsoft-only development organizations quite conspicuously have no similar choice. The VCL is cross-platform -- at least between Win32 and .Net. Applications build in Win32 using Delphi and the VCL should migrate relatively smoothly to the .Net platform today . VCL for .Net exists, and has been available to Delphi 7 owners via the Delphi for .Net Preview since last summer.

Now I am not at all claiming that the migration will be totally seamless -- you may need .Net version of third-party components, and if any of your code calls into the Win32 API directly, you'll need to update that. In addition, not all of the technologies that were in Delphi 7 will make it into Delphi 8, and certainly the presence of garbage collection in the .Net framework may affect the way your code works, but the migration is clearly not a complete rewrite as discussed above. Heck, at this year's Borland Conference, they compiled and ran in Delphi for .Net an application that was originally a demonstration application for Delphi 1 -- a 16-bit development tool! Can't get much more compatible than that.

This fact alone ought to be changing the way that developers and companies view Delphi. Delphi will drastically lower the overall total cost of a project by drastically reducing the time and effort needed to migrate a Win32 application that needs to be built today to the .Net framework tomorrow. Delphi doesn't lock you in to either Win32 or .Net and doesn't force you to move to .Net faster than you or your budget might want you to. Delaying the transition to .Net can also save money, as building applications in Win32 now for existing hardware can extend the life of that hardware rather than accelerating the hardware upgrades to run the .Net Framework.

Smart managers already know that they are stuck in a tough spot and smart Delphi developers will be quick to point out the advantages of using Delphi for new development. So if you have been looking for that silver bullet to convince your managers or your customers to use Delphi as the development tool for that upcoming project, you now have it.
