 Posted: Tue Mar 01, 2005 6:44 pm Post subject: delphi 7 program with Win98 memory error |
 |
|
I have been posting this message around on serveral different
newsgroups hoping to find the guru who knows the answer. Any
suggestions on a solution or a better place to post would be greatly
appreciated. Thanks.
We have created a program, with Delphi 7, that is approx. 9.8 MB and
our
problem is that it can not open on Win98. It works on XP and 2000 just
fine. The errors are below what appears on the screen. The system has
512
MB of Ram, so it must not be that memory it is talking about. We did a
little playing around with the software and removed 1 data module and
then
it seemed to work. I then readded that module and removed another one
and
that seemed to work too. So, we are not sure if it is related to the
number
of data modules we have in the package. We probably has approx. 10.
It
seems strange the software can not even open. As far as we know we are
not
trying to open or call anything on the initial opening of the software.
I
do auto create 2 forms, but the rest should be created on demand. Any
ideas
would be great. Thank you for your time.

There is a known problem with W95/98 and D3 executables. Apparently the D3
linker sets something incorrectly in the exe header. I had thought that the
problem was fixed in later Delphi releases, but this, IIRC, was the message
that error caused.
You don't indicate what your virtual memory settings are. Nor do you provide
any information on how much data space is being used by the app. These might
be factors.

Virtual memory started at letting Windows manage the file with 5 GB
free and 512 MB RAM. Other settings tried are 768 both min and max
settings and also 3 GB min and max.
Please let me know what you mean by data space. We are just trying to
display the main menu screen. The software app. links to databases in
DBISam to display the data values when the databases are accessed.
Your post is very interesting. Our previous verision of our software
was designed with D3 and paradox and we had the same problem when we
created apps. around 10 MB. On D3 we found that if we removed forms
or reused forms by changing lables, db editbox links, etc. on the fly
we were able to add things to the program. We were not expecting to
encounter this error with D7, so we are trying to figure out what we
can do to fix things. Thank you again for your time and insight.

don't know if this helps but i was reading somewhere that if you have
image resources embedded in your exe then it might be worth considering
creating a seperate DLL for them to keep the exe size down.

You are asking us, what is it that is kneeling your app on W98 machines.
Well, I would like to bounce the question back: "While you above have
proved that it's not the number of Datamodules, then what is it? Which
Form or Unit it is, that actually will kneel it down?"
I once tried to load one commercial application that was designed for
W2k/XP to a W98 machine and got error "This application does not run in
DOS mode", so also you may face just about anything.
I can also slightly quess that your problem on W98 may related to some
NT specific API call or something. Third party libraries, designed for
XP platform, are always suspectible.
But I do not have your application, so I could start ripping down the
9.8 MB package. And check at which point the error messages will
disappear.
I am pretty sure that at some point the errors will disappear, and you
are able to locate the critical Form.
You suspected that EXE size alone would do it. I would not bet on that,
I have succesfully run 7 MB D6 apps on W98 machines for years. Even old
16-bit WINWORD.EXE that was planned for Win 3.11 had some 6.2 MB
executable etc.

That is a common error message if you for instance try to load a broken
EXE file to a W9x machine. Maybe some call inside your EXE bangs the
file location pointer and makes W98 to re-load something or some parts
endlessly.
It could also be a known W9x Out of Resources problem. If you have for
instance hundreds of nice 32k colour depth, XP-decorated controls on
your MainForm. And also some other applications open on the background.
I am sorry, but I do not have better advice or suggestion than this.
Just plain work, ripping it down until, you have located some smaller
chunk where the final bug or incompatibility lies.

My guess is that you are somehow running out of resources.
With Win98 there is a 64kb limit, no matter how much memory
of any other kind you have. This is a legacy of its 16 bit DOS origin.
XP and 2000 have no such limit.
Load the resource meter and use it to check this theory.
