I am just wondering, is it possible to have two versions of DBISam installed into the one IDE at the same time but compile one app using one version of dbisam and another in the same IDE using a different version.

The reason I ask is because I have an app that is currently using 4.25 and as this is working just  now there is no real reason to change it just now  However I am making a new app that based on the original code and I want to migrate that over to 4.41 as it will be installed in a new site where I can freely upgrade the DB version without causing two many headaches.  Providing the new app work fine at the new site I will then bring them all into line but because the app is in a regulated environment, changes to version number cause many headaches with having to revalidate, lots of paper work etc which can be avoided if I can prove the other site works fine in the later version.

If this is possible can somebody shed some light on how to do this.  I tried but found it was causing me problems with the wrong version of the DB being compiled into the exe.

Thanks
David.

I believe you can do this manually - i'm not aware of any easy way to do
automate it though and maintaining it is PITA.



Install both versions in separate folders.

There are basically 2 issues :

1. IDE componwents. IDE package you can control by going to
Component->Install packages - remove 4.25 for example and add 4.41 or
vice versa (it's simply a reference to the appropriate bpl file). You
would need to manually remove other/add one every time you need to switch.

2. The other issue is the library search path. You again either have to
manually keep changing this to appropriate dbisam paths or if you only
have few projects then remove DBISAM paths from IDE global library path
and add them directly into the projects - this way each project refers
to its own proper version of dbisam.

I believe items above should be enough but have not tried this myself.


The other thing is to read the dbisam release notes and be aware of any
breaking changes between 4.25 and current one - main one i can think of
is the blob handling in 4.28 but there are few others.  This would be
issue is you need to share any common data between apps.

Since, from your description, it seems to be a short term issue I'd look at using a VM for the older version.

Odd you should say that, I am just at this very moment creating a vhd file just for this purpose however I would have liked the option to have avoided it and have two different version of dbisam working out of the same IDE as it is much easier.  If only there was an easy solution.... but happy to use a VM if no easy alternative can be found.

David,

I second what Roy said.
Its exactly what i always do - I always have a virtual machine set with the previous version - when i release e new version the previous project is copied to the virtual machine.

You can't have them both installed into the same IDE at the same time, but you can easily switch between the two using batch files, like this:

@echo off

set delphidir=<Delphi Installation Directory>
set enginedir=<DBISAM Installation Directory>\code
set designpkg=<DBISAM Design-Time Package Filename>
set runtimepkg=<DBISAM Run-Time Package Filename>

echo Copying DBISAM package to target folder...

if exist %enginedir%\%runtimepkg% copy %enginedir%\%runtimepkg% %delphidir%\bin\%runtimepkg%

echo Updating IDE search path...

testreg.exe rsdelphixe %enginedir% %enginedir%\%designpkg% %enginedir%

I've included the source for the testreg console application.  It contains all of the product IDs that are used as the first parameter to the application ("rsdelphixe" is just an example).  The application will update the path for both the design-time package, and the library search paths, and will then set a flag to tell the IDE that they've been changed.

Just make sure that your target Delphi IDE isn't running when you execute the batch file, and you'll be all set.  This is effectively what I use here internally for building/switching around test environments, and it's quicker than booting up new VMs (based upon VirtualBox - other VMs may be faster).

Excellent Tim thank you very much

Although the VM works, as you say, it is slow as treacle to boot but is a good excuse for me to upgrade my laptop with some more memory regardless

Thank you very much
David.
