By any chance when you build your DLL, did it depend on msvcr80.dll?

No, I get msvcrt.dll. That's your compiler's fault. Replace -MD with -MT in the
command line and it should lose that dependency.

Once I copy both jnior300.dll and the msvcr80.dll to the same
directory as jnior310tcl2.dll the error message of "couldn't load
library ....: this library or a dependent library could not be found
in library path" went away but I got a new error message "could not
find the section that owns the import directory".

That's a new one for me. I've never seen that before.

When I look at the
msvcr80.dll with "depends" it is a shade of red; with some functions
green and others red. I have three of these DLLs: One for win64,
amd64 and the other for Microsoft.vc80.crt. Each have some issue.

No clue.. all new.

Well I guess my post at 7pm did go through. This is the 2nd time that
happens.


Well, the "-MT" did remove the dependency on the msvcr80.dll. I do
get a warning message:
LINK : warning LNK4098: defaultlib 'MSVCRT' conflicts with use of
other libs; use /NODEFAULTLIB:library
But it appears I can ignore it for now. When I looked at the contents
of the new DLL via "depends" it showed that the name of the function
is screwed up. I reviewed the code and remember I need to use extern
"C".

Therefore line:
__declspec(dllexport) Tcl_AppInitProc Jnior_Init;
Became line:
extern "C"
{
__declspec(dllexport) Tcl_AppInitProc Jnior_Init;
}

Question: Why can't the name be Jnior310tcl_Init? I tried that and
TCL crashed because it is expecting the name to be Jnior_Init.

Anyways, I'm able to connect to the device, but I'm unable to
disconnect from it. When I pass the handler to disconnect, I get an
error message:

C:\Program Files\TCL_TK\tcl_c_api2>tclsh
% load jnior310tcl2.dll
% set a [ jnior::Connect "192.168.5.2" 9200 "jnior" "jnior" ]

% puts ${a}
10001
% jnior::Disconnect ${a}
Error 10004Error 115%
% exit
DLL Being unloaded now
C:\Program Files\TCL_TK\tcl_c_api2>

I even tried hardcoding the value, but nothing. Any ideas?
