Re: Run time error in TN5250.EXE version 0.17.4 forWindows

Hi John,

Frankly, I don't usually check sourceforge. This mailing list is the proper place to report problems with TN5250.

You say that removing the ASSERT from the move cursor routine fixes problems with the program crashing while XP is locked?! That doesn't make much sense to me.

Hi Scott,

The only problem I have that still appears in the current CVS version is
the problem with it crashing in XP when the tn5250 screen updates when
windows is locked. Our terminals using inquiry or update or reports don't crash because
they don't update when the window is locked. However, we have an
application for labor data reporting that updates a screen clock every 5
to 10 seconds, and it would crash with the screen locked. I don't think
this is the same problem that Bill Evans has.
I probably wouldn't have found the problem if the patch in CVS hadn't
been different from the patch in the mailing list archive:
http://archive.midrange.com/linux5250/200905/msg00005.html
I hope this helps someone.

Thanks for all your work on this project (all of you).
John Chambers

PS. I tried sending a message through sourceforge to you about this a
couple of weeks ago, but I only got an error message when clicking
'submit'.

Hi Bill,

I can reproduce your problem with the 0.17.4 release of TN5250. However, I can't reproduce it in the current CVS version (despite John Chambers assertion that the problem exists there as well.)

Can you please try the current version from CVS? Since you've had trouble building it yourself, I built a copy for you, you can get it
here:

http://www.scottklement.com/tn5250/tn5250-0.17.5cvs-setup.exe

Let us know how that goes...

Hi Bill
There is a patch for winterm.c in the repository that fixes some bugs,
maybe that one, but it is applied after 0.17.4. You can get mingw and
compile it yourself.

It was supposed to fix the crash in XP when the system goes into lock
mode, but it doesn't if there is any screen activity after it goes

into

lock mode.

The patch in the repository doesn't match the patch in the archives of
this list. The patch in the archives removes line 2154:
TN5250_ASSERT(0);
I recompiled it without this line, and it no longer locks up. I don't
know if this will fix your problem or not. I don't even know enough to
know if this might cause problems elsewhere, but it's worked ok on 4
systems for the last two weeks.

As I mentioned in my reply to James Rich, I'm pretty much out of my league with this stuff but I just wanted to give myself a stress test

-

pressing the envelope, so to speak. I ran into a roadblock during the

make step. However, it was educational looking thru the source code

of

the various modules. I even tried a source-compare between 17.3 and 17.4 since this "click on line 24" bug didn't exist in 17.3 and I thought I might "miraculously" see the issue. That turned out to be just hubris on my part. Nonetheless, it was an interesting exercise.

Thanks for replying.
