How are your impressions? Does it make sense to take effort, or staying with Delphi 7 isn't that worse? Thanks, Ruslan Back to top Bob Swart Guest Posted: Sun Jul 18, 2004 8:02 am    Post subject: Re: Porting Win32 applications to Delphi 8 Hi Ruslan, Quote: Have anybody ported a Win32 application to Delphi 8 / VCL? How are your impressions? Depends on your project, but for VCL GUI apps, it worked out just fine.

Not being sarcastic or trolling, but I'm interested in what are the specific reasons why you would move new apps or port old apps to .net rather than stay on Delphi for Win 32?

Presumably that is nearly equivalent to asking why someone should use .NET instead of Win32. I can see why .NET might be compelling for new apps, depending on the deployment circumstances.

Presumably that is nearly equivalent to asking why someone should use .NET instead of Win32. Pretty much - except qualified by 'for programming' and 'using Delphi'. Bob's "I'd make the effort." sounded like a ringing endorsement of a move/port, but I don't see any need for an immediate move, and the benefits seem equivocal for Delphi programmers (as opposed to MS Visual Studio programmers). So I was wondering what Bob thought was so good about .net that it warrants a move in the short/medium term (as opposed to just staying current with the technology by playing around with it). Quote: I can see why .NET might be compelling for new apps, depending on the deployment circumstances. Nicer threading, GC (if you go for that kind of thing), etc. GC strikes me as neither here nor there. I can see there are nice features in .net, eg reflection, and I take your word for it on the threading. But I haven't seen or heard any compelling reason for making the move now. It's obviously different for Dr. Bob as he has to train people so he needs to use it. But why should anybody else prefer it?

I would agree that for a large number of applications .NET is not a good move now. However I think you don't want to get caught out. IMO Java and .NET will be the two major players in the foreseeable future. You have to choose one or both and make sure that you know the technology and are gradually moving programs over. Some types of applications (web, web services, server tiers) obviously make more sense than others (GUI, Console) right now. -- Marc Rohloff [TeamB] marc rohloff at myrealbox dot com Back to top Lauchlan M Guest Posted: Wed Jul 21, 2004 1:56 am    Post subject: Re: Porting Win32 applications to Delphi 8 Quote: However I think you don't want to get caught out.

Quote: You have to choose one or both and make sure that you know the technology agreed, this makes some sense to me . . . (But only if you want to stay in programming for a living. The other option is to get out and do something else if programming is no longer RAD / fun.) Quote: and are gradually moving programs over. But I don't see why this follows. It's one thing to keep up to date with new technology, it's another thing to decide that this new technology is more productive or offers other business advantages to make it worth porting existing apps over to it. I find Delphi for Win 32 more productive than Delphi for .net or VS.net, and Win32 will be supported in future versions of Windows. So the only logic I see for moving things over is that, although you spend the time, effort and money to port it, and development then takes longer again costing businesses more money, the developers are then picking up deeper and more practical experience in .net programming. I guess it depends on how big your commitment is now to .net as a future. Quote: Some types of applications (web, web services, server tiers) obviously make more sense than others (GUI, Console) right now. Why are any of those necessarily better on .net than on Delphi with appropriate 3rd party components (EWF/IW, RemObjects, etc)? Regards, Lauchlan M.

Because things are going to change. You probably don't want to get caught trying to play catch-up.

Possibly, but they will be an important technology and if you want to start somewhere then here is a good place to start. -- Marc Rohloff [TeamB] marc rohloff at myrealbox dot com Back to top Atmapuri Guest Posted: Fri Jul 23, 2004 11:00 am    Post subject: Re: Porting Win32 applications to Delphi 8 Hi! Quote: Have anybody ported a Win32 application to Delphi 8 / VCL? How are your impressions? Does it make sense to take effort, or staying with Delphi 7 isn't that worse? 1.) If your code uses pointers with @ and ^ some areas may need a complete rewrite. 2.) Your app will run noticably slower than in D7. (3-5x is said to be the standard). I can confirm that. Those are the immediate results. If your app "requires" to work with WinAPI or other W32 dll's interfacing those from .NET will be much more difficult than it is in Delphi 7. DotNet has a very big set of classes and features. I am sure you wont be dissapointed once you start exploring them, if you can forget about about some of the speed. Regards!
