Hi

Calling a 32bit dll from IDL 64 bit doesn't work (see below). Is this
normal behaviour?

IDL> print,!version
{ x86_64 Win32 Windows Microsoft Windows 7.1 Apr 21 2009 64 64}
IDL> print,call_external('test.dll','test',2u,/ALL_VALUE,/I_VALUE )
% CALL_EXTERNAL: Error loading sharable executable.
Symbol: test, File = Test.dll
%1 is not a valid Win32 application.

Normal behaviour (IDL 32bit):
IDL> print,!version
{ x86 Win32 Windows Microsoft Windows 7.1 Apr 21 2009 32 64}
IDL> print,call_external('test.dll','test',2u,/ALL_VALUE,/I_VALUE )
10

Dll file used: http://xrdua.ua.ac.be/public/Test.dll
