Keyboard-Error in Application after installing SP2 for Windows XP

Hello,

I'm using an application created in Windows98.
I get to run it on Windows XP while using SP1.

After the installation of SP2 there are some strange errors.
(In advance: the source-code is lost)
If one is using a table into the application (It's like an excel-sheet)
the error occurs:
If you go into a field of the grid by using the tab-key and hit any key
inside the field,
this key is written multiple times into the field.
For example: k = kkkkkkkkkkkkkkk
l = llllllllllllllllllllllllllllll
each key with a different numbers of copies.
This is related only to the first key.
After the first one can write as usual.

If you go into a field with a mouse-click, everything is allright.
Also if the first key is esc or del.
But this is still a bad workaround for fast working.

Perhaps anybody can help me with this.
I'm desperately searching which change between XP SP1 and SP2 is
responsibel for this behaviour.

It is not a matter of keyboard-options!
And it happens on every pc I tried out.

Any tipps?

Best regards from Germany

Johannes

This is a C++ language forum. Do you have a C++ language question?
If not, we can't help you. You need to find the newsgroup where
they talk about Windows XP.

Hello Victor,

the source-code is c++.
I guess it has something to do with the sourcecode?

Please note that most newsgroups have posting policies and FAQs

Please read up on this first, as we get a lot of postings that are

Hello Jens,

so I am sorry.

I guess not. I think they are not very interestet in the source-code of
my application.

I thought somebody has come around this problem while programming in
c++
That's the reason why I'm posting in this group.
But I would be thankful for a group which can help me with a C++ bug in
my application.

In principle, there surely are windows programming newsgroups, but
without any source there isn't much you can do about it anyway.
Even if you knew a change in the API that caused this, what would you do
about it without sources?

Hello Jens,

my Idea is that:

I desperately need to do something about this problem.
So I would try anything.

I thougt: If there is any idea what part of the source-code is
responsible,
one can find out, which part of the SP2 would do the harm.

And then I have something I could hold on.
I had some luck with this program with another problem through copy
some windows-file in the program-folder.

a) We do not even know what parts the lost source has.
b) Even if we did: what change in Windows could affect the program, is not
topical here.
Ask in a windows group about known problems with upgrading to SP2.

I did.
They say it is a c++ problem which is not topic in windows.
Of course it is a problem of c++ there
and it is a problem of windows here.

So I see I'm on my own again.

And I don't want to annoy you with c++-problems.

You are not annoying us with a c++ problem: as long as there is no source,
there is no C++ problem.

Think about it: How are we supposed to say anything meaningful without the
slightest clue as to what the C++ code of this program looks like? For all
intents and purposes, you have a problem with an executable binary. It is
immaterial that you happen to know your binary came from C++ source code.
All possible C++ clues as to what could cause your problem have been lost
with the source.

Hi,
to be more specific:

there are only remaining fragments of the source-code.
Some parts are missing and compiling again run into errors.

I know the programmer by myself, I sat behind him some time while he
was programming.
I'm quite sure it is C++.

What I want to say with "The source code is lost" is, that there is no
way for a resolution by changing the source code because some parts of
the source code are lost. And the programmer is lost to. I tried to
find him for five years now.

As long as I don't know which part causes this error I think it is
useless to post any lines of the code.

Johannes Meyer wrote:You're absolutely correct. It's useless to post fragments if you are
unable to resurrect the entire program from them. But please understand
this too: it's useless to discuss any behaviour of your program *without*
the code. It's also useless to post questions about Windows XP SP2 here.
They are simply off-topic. It seems you have no solution... But, wait!

You have a solution: get somebody to write the program again for you. If
your program works somewhere (like Windows 2K or NT) you could try to
find a willing and able programmer who might want (for some compensation)
to [re]create the program by looking at the working executable and at the
remains of the source code. It's called "reverse engineering" or "work
from a prototype". You're strongly advised to work out P&L statement
before embarking in that direction. Reverse engineering is costly.

Good luck!

Dear Roland,
many, many thanks for this group.
I don't even need to ask any questions in this c++ group.
Even looking around there was the solution for my problem.
Anythink is allright now.
