<P><H1><A NAME="ide3">16-bitAppl with delphi 2??</P></A></H1>
<P><I>From: "Rodney E Geraghty" <gerarod@ibm.net></I></P>
You can't create 16-bit programs using Delphi 2.0 it is 32-bit only. The
good news is that, as far as I know, all versions of D2 also come with
Delphi 1.0 on the CD which is 16-bit. You'll have to load it or you can
run it from the CD by using the Delphi16/RunImage directory on the CD.
Note that this will not work if you have used some of the unique Win95
components in D2 or if you have used Win32 specific API calls. To do this
you'll have to copy the *.dpr, *.dfm and *.pas files for your app to
another directory (do not copy the *.dcu, *.opt or *.res file that D2
generates or you'll get errors) and recompile them using D1.
<P><H1><A NAME="ide4">Sharing ObjectRepository</P></A></H1>
<P><I>Delphi Developer's Jrnl <tim_gooch@cobb.com></I></P>
To share form and project templates among Delphi 2.0 users, the process
is a bit more complex than for Delphi 1.0, but the main idea is the
same. The biggest difference is that you can add a form to the Object
Repository that doesn't exist in the same directory structure as the
Repository itself. Because of this situation, Delphi 2.0 can't assume
(as Delphi 1.0 did) that all the form or project template files will be
in the same directory or a predictable subdirectory. (This disparity
also has important implications for the forms and projects that you want
to share from the Object Repository. We'll describe these implications
shortly.) <p>
To share an Object Repository among several users, you'll do the
following: <p>
Copy the Object Repository files you want to share to a new
directory. <br>
Copy the Delphi32.Dro file from the \Delphi 2.0\Bin directory into
the
new Object Repository directory. <br>
Find all occurrences of the old Object Repository directory path in
the
new Delphi32.Dro file and replace them with the appropriate path
to the
new directory. <br>
Add a BaseDir= entry to the Repository section of the Delphi 2.0
System
Registry entries to identify the location of the shared Object
Repository. <br>
Restart Delphi 2.0 for each user. <p>
As you might guess, the one problem in this process arises when you try
to share a form or project that doesn't exist within the default
\OBJREPOS directory structure. If you've added projects or forms to the
Object Repository and the directory doesn't exist in a subdirectory of
the main Object Repository directory, you'll need to copy the
appropriate files for those projects and forms to the new directory. In
addition, to reflect the new paths, you'll have to adjust the path
statements in the Delphi32.Dro file that
reference these files. <p>
If you don't make these changes, as each user loads the common
Delphi32.Dro file, the user's copy of Delphi 2.0 will begin searching
local hard disks for projects and forms that don't exist. (These
projects and forms exist only on the system where you created them.) <p>
<U>****** Example *******</U><p>
Now let's specify a shared Object Repository for Delphi 2.0. To begin,
create a new directory named C:\Object Repository 2, and then copy all
of the files and directories from the \OBJREPOS directory into the new
directory. In addition, copy the Delphi32.Dro file from the \Delphi
2.0\Bin directory to the new directory. Launch a text editor and open
the Delphi32.Dro file. In this file, find all the occurrences of the old
Object Repository path, such as <P>
<tt> C:\PROGRAM FILES\BORLAND\DELPHI 2.0\OBJREPOS</tt><p>
and replace them with <p>
<tt> C:\Object Repository 2</tt><p>
This search-and-replace task will change the Delphi32.Dro file in
several places. Next, launch the Registry Editor application
(REGEDT32.EXE), and locate the subkey named <p>
<TT> Software/Borland/Delphi/2.0/Repository </TT> <p>
in the HKEY_CURRENT_USER section. In this section, add a new string
value (data type REG_SZ) named BaseDir, and set its value to <p>
<tt> C:\Object Repository 2</tt><p>
When you finish adding the new string value, exit the Registry Editor.
The next time you launch Delphi 2.0, the new directory will contain the
project and form templates in your Object Repository. <P>

Here's a routine that works for Delphi 1. If you're using Delphi 2 and it also seems to work in that environment, please let me know.

Bool(PWordArray(MemL[DSeg:36])^[8]);
