Hi,
I have Windows 7 professional service pack version 1
Intel Core TM i72760 QM CPU 2.40GHZ
Visual Studio 2005
Visual Fortran version 10 for windows
IA-32 Build
I have an application that works just fine when the Threading model is Apartment.
The application is called from a c++ interface.
The interface transfers the name and path of the source data file, and some other
simple run paramaters into the target fortran dll.
The target fortran dll performs long and complicated calculations, also calling other fortran dlls, and c++ dlls, and then passes a simple set of results back to the calling interface.
Now the user wants to go with a registry setting of Free for the threading model
as shown below:
HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{834EE1F7-94F0-4946-8759-BDECED57CC3E}\InprocServer32
Change the "ThreadingModel" value to "Free".
This does not work at all.
It looks the Fortran dll is attempting to start the first 4 source
data files, but is jumping into the 5th data file without doing preliminary initializations.
There is no orderly flow in the debugger to follow.
Is there a simple way to get this working multithreaded set to Free in the registry as above??
Or does the application have to be rewritten to provide special 'thread safe' memory allocations??
Are there any textbooks that can be ordered from amazon that would show a multithread application
that opens a file, reads it, performs calculations, and then passes the results of the calculations??
Thanks for your help
Bill
