Nice to see that the love of Delphi goes on. I have two Delphi 6 applications that I want to port to 32-bit Delphi. I have a few questions if you can help: 1. Can I just load in the original forms, like load the Delphi 6 project? I know that I will have to find alternatives for many of the 3rd party VCLs I used in the programs. But beyond that, are there going to be other fundamental changes I have to make? on an initial copmpile of my old app in D 2007, I get this error message: [DCC Error] F2141 Bad file format: 'C:\Program Files\Borland\Delphi6\Lib\rtl.dcp' can you tell me what that is about? 2. I am assuming that I need to compile for 32-bit computers on a 32-bit machine. Can the same program I write and compile on my Windows 2000 machine run on Vista 32 and 64 bit and XP? Are there preparations or any modifications I will need to do for the different environments the apps will run on? 3. Installing Delphi 32 on my Vista machine, which has a beta version of Vista on it, yielded and error 2337. Can you tell me what that error is so that I can complete installation? 4. My apps use the BDE but the actual databases are very simple and small. Is there a built-in replacement in D2007 that I should consider using? I have the Pro version. I mention this because I saw some posts that say that using the BDE really doen't work without problem. 5. Is there any built-in installation making program in D2007 Pro? I have been using Inno Setup Compiler with great success in the past.

Check your project settings - specifically runtime ones, and paths. Quote: 2. I am assuming that I need to compile for 32-bit computers on a 32-bit machine.

D2007 doesnt produce 64bit apps - or if it does, I completely missed that, all the apps should run on a 64bit machine Quote: 3.

Im impressed the beta version of vistas not timed out yet, 2337 I believe is a .net issue, Im gonna stab at a guess of: because its a beta it doesnt have all the patches it needs and in trying to install .net2 on vista its run into an issue.

Quote: I have a few questions if you can help: 1. Can I just load in the original forms, like load the Delphi 6 project? If you have D2007 replacements for all 3rd-party controls you use in D6 available, or if you have the source for the components you use and can get them to recompile in D2007. You would need to rebuild the design-time and run-time packages for the components. Otherwise the D2007 IDE would report heaps of error when you try to open the project forms. Quote: I know that I will have to find alternatives for many of the 3rd party VCLs I used in the programs. But beyond that, are there going to be other fundamental changes I have to make? No, yes, maybe. Depends on what your program does. Codegear/Borland has always taken pains to make sure older code can be ported without too much trouble. My old D7 projects all recompiled on first try in BDS 2006, for example, and worked without problems. I use very few 3rd-party components, though. Those are usually bigger trouble since they do not tend to be as compatible with older versions as the RTL and VCL itself. Quote: on an initial copmpile of my old app in D 2007, I get this error message: [DCC Error] F2141 Bad file format: 'C:\Program Files\Borland\Delphi6\Lib\rtl.dcp' When you copy the project to a new folder in preparation for migration copy only the PAS, DPR, DFM, DPK files and any resource files of your own. Do not copy the DOF and CFG file. You may have to reconfigure some project options (like the main icon and version information, or the package list if you build with run-time packages) this way but this makes sure you do not get harmful baggage, like pathes pointing at your old D6 library). As the next step open the DPR and DPL files in notepad and check the Uses or Requires clauses, respectively, for pathes that refer to your old D6 code base. Change those to point to your new D2007 project folder. Then try to open the DPR or DPK file in D2007 and if that works call up the project options and set the search path as appropriate for your new D2007 environment. Make sure you do not use any pathes that contain D6 compiled code (dcu, dcp), that only leads to confusion. Quote: 2. I am assuming that I need to compile for 32-bit computers on a 32-bit machine.

On a Win64 platform your programs will run in WOW32 environment, basically an emulation of the standard Win32 environment. If you want to make a Win64 version of the program you will have to wait a bit longer, D2007 only creates Win32 executables. Quote: 3. Installing Delphi 32 on my Vista machine, which has a beta version of Vista on it, yielded and error 2337. Can you tell me what that error is so that I can complete installation? Vista is a problematic environment if you come from XP or Win2K. Do not use a beta, D2007 is not certified to work with that. Quote: 4. My apps use the BDE but the actual databases are very simple and small. Is there a built-in replacement in D2007 that I should consider using? I have the Pro version. I mention this because I saw some posts that say that using the BDE really doen't work without problem. That is more a Vista problem than a D2007 problem. You can use Interbase (I assume d2007 comes with the local interbase edition like prior versions) if you cannot get the BDE to run (D2007 still supports it with Paradox and dBase database formats).
