thanks to help me...
this is a part of my matlab code:

.....
mydcf= '6703c60.dcf'

loadlibrary('mil', 'mil.h');
M_default= '10000000';
M_default= 'hex2dec(M_default);

v= int32(1);
p_app= libpointer('int32ptr',v);
calllib('mil', 'MAppAlloc', M_default, p_app);

psys= libpointer('int32ptr',v);
calllib('mil', 'MsysAlloc', 'M_system_meteor_II',M_default,
M_default,psys);

.....

In this code i used a call to 'Mil.h'. I found this file on the net,
this file is write only for Matlab.. but I can't used it with IDL...
I have a library called 'Mil.dll' and i tried to 'translate' this part
to IDL:

...
mydcf= '6703c60.dcf'
path= 'c:\test\mil.dll'
res =call_external('mil', path)

m_default='10000000'x

v= float(1)
p_app= ptr_new(v)
return, call_external('mil', 'MAppAlloc', M_default, p_app)

psys= ptr_new(v)
return, call_external('mil', 'MsysAlloc',
'M_system_meteor_II',M_default, M_default,psys)
...

but it doesn't work...

the first error it's in the first call_external... The dll isn't
open...

if you have a idea....
thank
