Runtime packages question

rbuser

I am building a Delphi application which will use report builder in the
Reporting Module. The application makes use of Delphi runtime packages and
therefore i have to ship quite a few runtime Report Builder files which i
presume, go into the Windows System directory. (I have tested it with them
in the System directory and all works fine). My question is this :
What will happen if (and probably when) a users machine already has a
program that users a different version of Report Builder ?
As i have installed my program and overwritten all these older bpl files in
the system directory.
Do the old and the new version of the bpl files have different names so this
kind of thing won't happen ?

Thanks
John

We don't add build version info in with the packages. You'll have to check
the date of the files to determine if the build of the bpls is from a
different build of RB.

Ok, Jim, so if i check the existing files and find they are from a previous
build then what do i do ?
If i overwrite them with the new ones then my program will work, but the
other(existing program will not (will it ?)).
If i leave the existing files then the old program will still work but my
program will not.
If i have this correct then have you got any suggestions on how to overcome
this issue please ?

Thanks

Hi John,

overcome

this can only be solved by putting the BPLs into the application directory,
that's a general Windows-DLL issue.

directory,

Ok, then just to clarify.
If i put all the bpl files needed for my program into the same folder as my
program exe file is in then when my program needs to access them, it will
first look in that directory. If it finds them there it will use them and
not even bother looking elsewhere ie the Windows\System directory ?
Is that correct ?

Hi John,

my

Yes, otherwise my answer wouldn't make any sense. But don't believe it - do
a simple test by yourself.
You can use any system tool to verify what files are in use or accessed by
your app. (www.SysInternals.com)
