Hi all,

I am programming Sybase using ct-library version 12.5.

While executing the cs_ctx_alloc command it results into an error returning CS_FAIL.
The command that i am excuting is as follows.
retcode = cs_ctx_alloc (CS_VERSION_125,cntx_ptr );
RETURN_IF( retcode, "cs_ctx_alloc ");
the command return 0(CS_FAIL). The version of sybase that is installed is 12.5.
Can anyone help me to find the cause of this problem.

Thanks in advance.

Install an error handler (client callback). This should give you the
reason for the failure.

Hello Sir,
First of all I would like to thanks for your reply.
But the problem I am facing is only when I integrate the code with
an MFC code,else in a console based application it runs perfectly.
Also the error comes while initializing the context,and I had read
somewhere that client and server message handlers(callback functions)
can be set only after initializing the context structure(Help me if
I'm wrong here).
So what might be the cause of the problem.

Waiting for your reply.....
Thanks again....

Regards,
Amol Natekar

Hello,

Try searching your PC for duplicate Sybase dll's like
libct.dll, libcs.dll, libcomn.dll, libblk.dll, etc.

If your application picks up an old dll it won't be
able to initialize the context to CS_VERSION_125.

I'm not sure what you do differently to integrate with MFC
but if the application can not find the Sybase dll's, that
could also cause this type of error.

Good luck,
Neal

Hi,

I had searched my machine for existance of any other dll's but haven't
found any of them except in sybase directory where the libraries are
installed.
Can you suggest me any other reasons for this problems.

Thanks for replying.

Hello,

I'm still not sure what is different about your program/environment
when you compile it as an MFC versus console application. Perhaps
it can not find the Sybase dll's.

When you run your application, does it create a "sybinit.err"?
This file is created by default when the Sybase software can not
initialize properly:
================================================== =================
C:\Neal\Firstapp\Debug> firstapp.exe

C:\Neal\Firstapp\Debug> type sybinit.err


The context allocation routine failed.

The following problem caused the failure:

Invalid context version.

Open Client Message:
Message number: LAYER = (5) ORIGIN = (3) SEVERITY = (5) NUMBER = (131)
Message String: ct_init(): network packet layer: internal net library error: Fai
led to open Net-Library localization file
================================================== =================
In the above example, I changed my PATH to exclude the
Sybase directory containing the Sybase dll's.

If this doesn't help, perhaps you can zip up a simplified
version of your project and send it to Sybase technical
support?

Thanks,
Neal

HI,

I had just reinstalled my sybase libraries and the things are working
now. I guess it was the same problem that you suggested me in your
first reply(existence of duplicate dll's).
Thanks for your time and suggestions.
