The work and posts by steelbytes and molotov are milestones in this fields, nevertheless I'd like to bring to your attention a slightly different approach, implemented as a library containing the missing functions, so that it is compatible with optimization as well:
Legacy Extender for Visual Studio 2005/2008
The toolkit contains a linkable library and a command to edit the version and recalculate the checksum (similar to editbin.exe once provided by Microsoft).
The Legacy Extender library also implements some Unicode functions which are present in Windows 95, but which do not work on an out of the box system (your application will start, but it will fail on these functions). These are also referenced by Visual Studio. Your critical expert opinion is of course most welcome.

I have at last found time to write a patcher to modifiy a compiled .exe/dll.
why not just mod the crt .lib? umm ... because I feel that is MS's job :-)
thinking of releasing on steelbytes.com, but need to test it a bit more first.

re: 'global opt' vs 'whole prog opt', yeah I typed the wrong thing when I quickly scribbled that post :-)
re: updating my page with those steps, that was my intention affter writing them for you - I was just waiting for you to get it working (ie, validate the steps). page updated :-)
it's a shame that we have to do this messing around, as it will just keep people from upgrading from VC6 for even longer :-) a conspirisist would say it's MS attempting to force our hands in dropping support for old windows. bit of a shame since my programs work fully on win9x/nt4 when compiled with vs2003 and doing my method requires turning off whole prog opt if I use vs2005 - not desirable.
I have been considering writing an exe patcher to apply these changes to an already compiled .exe (or .dll), but just haven't had the time. I wonder if I could then get vs2008's remote debugger running on win9x/nt4 ...
hey, if you have email addy for whomever maintains sysinternals's apps such as handle.exe, then you may want to formard this info to them

I have my test program working on 98 and ME now - thanks for your persistence.
 
I had taken this to mean /Og which the default optimization (/O2) includes. I had previously changed the optimzation setting to /Od, to no effect.
This made me look at that Whole Program Optimization setting (/GL); disabling that seems to have been the key.
EditBin.exe from VS 2003 and the code from Part 1 each worked, in combination with the functions from Part 2 and Part 3.
Wonder if it may also be worth including your list of steps on your page... Edited by molotov - 23 April 2008 at 4:09am |

please past your build log here, as I am interested in reading the warnings that the linker generates when resolving the multiple references to these two functons. PS, test 5 mins ago with a hello world test from scratch ... |

Even after disabling compiler optimization (/Od), and using the functions in Part 2 and Part 3 from your page (in conjunction with /FORCE:MULTIPLE), and running the binary through the function in Part 1 (or VS2003's EditBin.exe), the executables created in VS 2008 do not function on Windows 98 SE or Windows ME.
In the case of EditBin, Dependency Walker verifies the Subsystem Ver is 4.0, and in the case of the function from Part 1 Dependency Walker shows the OS Ver and Subsystem Ver both as 4.0.

were you compiling with global optimisation? if so, it seems that you can't reliably override the CRT functions.

I used VS 2003's editbin.exe, and was no longer presented with the following dialog:
I finally made a 98SE and ME VM; the app didn't run, probably due to Part 2 and Part 3 from your page. Added those functions, and rebuilt, but still no joy...
Got around those with /FORCE:MULTIPLE to ignore the second definition, but the apps still wouldn't run... (No warning, and no response from the app.)

thnx for the suggestion (reminder) - updated. what inspired me to post this thread was, that I saw that sysintnerals had published a new ver of handle.exe that is supposed to work on win9x - it doesn't :-) It looks like sysinternals have bumped into this set of problems and hadn't realised part 2 and 3 of my post ...
