I have two multithreaded applications the runs perfectly in NT, 2000 and XP, but when I port it to 98 they die. The first has no user interface, and for some reason ends up in a deadlock, where half the threads are stuck in the PumpMessage loop, and the other half are sleeping. None of the threads (except the main thread) have any windows. The secondary threads that are stuck pumping come from CSockets. As I said, this has worked fine on NT based kernels.
The second program throws a page fault in Kernel32 or quits out of all the threads with a result code of -1. Unfortunately, the VC++ debugger won't trace to the line (or area) that is causing the problem.
Does anyone know what the difference is that would cause such problems?
Thanks.

Ten bucks you are using an API not supported on 9x.

I know what you're thinking punk, you're thinking did he spell check this document? Well, to tell you the truth I kinda forgot myself in all this excitement. But being this here's CodeProject, the most powerful forums in the world and would blow your head clean off, you've got to ask yourself one question, Do I feel lucky? Well do ya punk?

Depends can't find anything. Do you have a suggestion on how to determine this?

Bad idea, in my opinion.
CSocket[not thread safe] misbehaves in mutlti-threaded apps.

If you implement CSocket correctly you can safely use it in multithreaded apps. This is actually the easiest way to set up a server that can respond to multiple clients at the same time. I have had no problems with this in NT.

I don't know about the first program, but in the second, you're not passing NULL as the last parameter of CreateThread() are you? This is supported on NT etc. (after all, why do you need the thread id, when you get the thread handle) but causes a kernel error in 95/98/Me.

I'm using AfxBeginThread which doesn't have this parameter:
m_pThread = AfxBeginThread(SequenceThread,this,THREAD_PRIORITY_HIGHEST,0,CREATE_SUSPENDED);
It is weird though that 98 generates negative thread numbers (as seen in the debugger)...

Which command can convert .obj to .lib?
This is simple but i forgot it.
Many Thanks
|
|

I didn't even know of a conversion utility that did this...?
I would specify Win32 static library in the New dialog.
This tells vc++ that the output of compilation will be a lib file rather than executable.

Thanks for you reply.
My situation is that the .obj file is not produced by myself. it's a
commercial package which i must include into my project.
This package, actually, is not big at all, it's only 28KB. however,
I only user no more than 3 function in the package, Therefore, convert
this .obj to .lib do reduce the size of my application.
Cheers.

You cannot convert just about any obj file to lib!!!

I think he's looking for the lib utility. You can use this to combine object files into a static library. Its been a long time since I've created a static library for anything.

Huh...Nish i'm missing something here...
Just about doesn't seem right...if i'm wrong correct me...if i'm right tell me too...cuz i'm gonna finally tease you about yer English. 
Out of pure jealousy (spelling) of your grammer being better than mine  of course.
Hooo...i'm getting excited...am I right...? 
Laterz!

It's spelt "grammar" and not "grammer" 
My sentence :-

This means you cannot take any random obj file and convert it to a lib file. "just about" is a phrase.

Damn it Nish...
I'll catch you one day...
See you have the benefit (i don't really know, but i'll assume) of not learning english in quite the same setting as me. When I speak it's full of normal slang, Sooo sometimes proper grammer or pronounciation doesn't seem right to me, cuz well...it's the only language I know and I like my enlgish...not websters or whoever...Plus I speak Canadian English eh!!!
For instance...in Canada Color is Color not Colour...like I think the Brits or Americans spell it. Actually I may have that backwards... 
So yeah...ummm...thats my excuse for lack of literacy...or whatever it is...
Perhaps we should all communicate using a hybrid..??? of C++ or something...
if(Nish)
AfxMessageBox("Whats up?");
else
AfxMessageBox("Are you there..?");
This way there would be no correcting, cuz the compiler would catch your gramm(er) mistakes before sending out...?
Cheers man!

Actually I learned english by speaking english too. In school we had to use english compulsorily. It wasn't easy doing that when you are 4 or 5 years old and you dont know the language except for that apple-ball-cat stuff the teacher shows you on the board. But then you catch up and by the time you are 8, you can speak the language well enough to insult someone's grandparents without using any explicitly abusive words.

English is pretty popular.
Yeah I insulted grandparents too, but not with English...I used the filipino I picked up from friends. They never knew what I was saying.

lib name.obj
Will create name.lib.
lib name.obj /out:othername.lib
Will create othername.lib
HOWEVER, it won't do you any good. Object files in libraries are included as a unit. It won't pick routines out of the object file.

I'm assuming your talking about an NT-based machine? Use the command line...
C:\>net stop dhcp
C:\>net start dhcp
You can do this behind-the-scenes from a program. Just remember you won't get control back until the statement finishes executing (in the same thread that is). If you are looking for something different, please give more details.
