Hi all.

We use acucobol.CVM class from wrunnet.dll to call COBOL program from .NET module.

 

Unfortunately we get FALSE from the Initialize() method and we do not undestand why. 

Is there a way to get a more detailed error code/message? Some kind of log or something like that ?

 

Thank you

A first step would be to call Initialize() with a command line that includes a trace file and a config file that turns on tracing:

Initialize("-c myconfig -le myerr.txt myprog")

And then make sure that myconfig has at least:

A-TRACE 3
FILE-TRACE 3
FILE-TRACE-FLUSH TRUE

Hopefully the myerr.txt file will have some more information about what might be failing.

Hi rzack.

I tried your suggestion but with no result (I mean, no trace file created).
I guess that the runtime fail before starting.

Hi all.

I finally get the solution.

My bad ! !

We was trining to call the wrun32.dll from a 64bit .NET application.

Simply changing the configuration from "Any CPU" to "x86" we solve our problem.

 

Thank you all.
