Install D6 Update 2 now: Supporting original W95 in Delphi 6.02
John Kaster (Borland)
Jordan Russell mentioned problems with original versions of Windows 95 and
Delphi 6. These are an unofficial, unsupported options, since Windows 95 is an
unsupported OS for Delphi 6.
Anyway, here's your options:
1. Install the Win95 DCOM 1.2 Service pack on those machines that have not
been touched at all since Windows 95 initially shipped.
2. Change the following code in Variants.pas to look like this:
procedure NotViaOS(var Dest: TVarData);
begin
// VarResultCheck(VarNot(Dest, Dest));
end;
procedure NegateViaOS(var Dest: TVarData);
begin
// VarResultCheck(VarNeg(Dest, Dest));
end;
Then include Variants.pas in your project and build without packages.
This should remove any dependencies. All the other string conversion routines
in VarUtils are already available in the original Win95. That includes these
from VarUtils:
function VarI4FromStr(const strIn: WideString; LCID: Integer; dwFlags:
Longint;
out lOut: Longint): HResult; stdcall;
function VarR8FromStr(const strIn: WideString; LCID: Integer; dwFlags:
Longint;
out dblOut: Double): HResult; stdcall;
function VarDateFromStr(const strIn: WideString; lcid: DWORD; dwFlags:
Longint;
out dateOut: TDateTime): HRESULT; stdcall;
function VarCyFromStr(const strIn: WideString; lcid: DWORD; dwFlags: Longint;
out cyOut: Currency): HRESULT; stdcall;
function VarBoolFromStr(const strIn: WideString; LCID: Integer; dwFlags:
Longint;
out boolOut: WordBool): HResult; stdcall;
function VarBstrFromCy(cyIn: Currency; LCID: Integer; dwFlags: Longint;
out bstrOut: WideString): HResult; stdcall;
function VarBstrFromDate(dateIn: TDateTime; LCID: Integer; dwFlags: Longint;
out bstrOut: WideString): HResult; stdcall;
function VarBstrFromBool(boolIn: WordBool; LCID: Integer; dwFlags: Longint;
out bstrOut: WideString): HResult; stdcall;

I'm curious: Is that allowed ?
If so, it means that component builders can also use some of the Delphi dfm
files in the sources directory, right?
Stephan Marais

Use - yes, distribute - no. This can in some instances cause problems like with
the personal edition that comes with no source and therefor might not even have
the dfm found in the source directory. You have always had the right to modify
for your own use the source in the source directories. You may not distribute
those changed files (you may distribute the instructions on how to change the
files, but not the changed files themselves) nor may you build new packages with
the same name as the Borland supplied packages with your changed VCL.

on the unpatched Win95. I can't imagine those customers are getting many
other newer programs to work very well either. That version of Win95 doesn't
have comctrl32.dll (sp?) IIRC.

Hmm, commenting out code makes me a bit uneasy. :)
Is there a reason why Variants.pas can't just be replaced with the
Variants.pas from D6U1? Are other units in D6U2 dependent on the new
Variants.pas?

Jordan Russell
Jeff Overcash (TeamB)
The number of changes for Variants.pas between UP1 and UP2 were significant.
Variants.pas in UP1 was broken in a lot of places. I'm sure there are several
changes in UP2 that expect the correct behavior of the Variants.pas in Up2 and
not the incorrect behavior in UP1.

Simply time management. I thought I might be able to get a resolution in less
time than it would take to answer the same question over and over.

There should also be some significant performance gains in the new version.

Does this apply to apps that don't use variants?
I know some of the components might pull that in, but if I write a simple
app IE like a console app it's still going to work on old Win95 boxes right?

Thanks for the quick response.
Anyone has any idea what implications uncommenting this code has? As far
as I can see it these methods are only called for unknown OLE objects
(like IInterface or IUnknown interface pointer according to the Delphi
help file). It seems that for these kind of objects NOT or NEG don't
have a meaning at all. Am I right???

I don't think the issue is that many or any of Borland's customers are
running Win95 for development.
The issue is that programs created with Delphi still need to run on
Win95. A lot of business users (ie *our* customer's not Borland's) are
still running Win95 - crazy or otherwise - and many of us (myself
included) need to be able to write programs that they can run.
I can't say to my business customers "here's my app that will cost you
5000 pounds - oh and by the way you need to upgrade all your systems
to xxx for just half a million".
I wonder how many potential purchasers of your newsreader will still
be running Win95? :-)

To the point.
I on my side am not critizing Borland for this at all, most of us
have earlier versions of Delphi that can be used. The thing is that
some Delphi users may get an unpleasant surprise.

Excellent! Nice job John. Wise man too.

They can't redistribute apps either, so the issue is a lot smaller. Win95 is after all
unsupported.

Any program that uses the Classes unit (which includes all programs that
use forms, data modules, etc.) pull in the Variants unit, which loads
oleaut32.dll. This happens even if you don't use Variants in your program.
The problem is that the program doesn't know whether a DFM will have a
Variant property value stored in it, so the DFM streaming system always has
the Variant-reading code linked in.

You are correct. So don't use the hacked Variants.pas for a program that
uses SOAP, Corba, COM, etc.

Another approach doesn't involve changing the source code. Add VarUtils.pas
to the project, and compile with GenericOperations defined in the project
options.
David Marcus
interesting, I think a more relevant question is how easy it would be
for Borland to modify this particular change so exe's would still run on
ancient versions of Windows 95. If it isn't particulary hard, then it
would seem this would be good to do in this case, with the understanding
that Borland would not promise to do this in the future.

Again, it's not so much a problem that Borland decided to quit "certifying"
Windows 95, it's that Windows 95 support was forcefully removed in a
*patch*.

How can support for Win95 be removed, when D6 did not support Win95 in
the first place? The fact that some apps compiled with D6 worked on
Win95, was more down to luck than anything else.

Fact: D6 apps ran without any problems on Windows 95, they did not after
SP2.

No, it was good old Borland engineering. By creating a great VCL it hold
for a long time even without certification.

system like Windows NT 4.0 or Win2K. Depending on my tests on Windows Me, I
might just have the program automatically detect the OS and shut down (with
a message explaining why) if it is running on variants of Windows 95.

That'll be the geeks only newsreader then <g>. I assume it will also run
on XP. It's probably a good idea to let the installer prevent
installations on Win9x platforms.
