I cannt load the HP's instrument driver DLL hpe1432.dll in matlab2007a

my command line is:

>loadlibrary('hpe1432', 'hpe1432.h')

but an error tip appears, which somehow likes:

there was an error loading the library "mypath\hpe1432.dll" Error using ==>loaddefinelibrary

the mypath is the path in which the files hpe14332.dll and hpe1432.h are located, and the path has been added to the ML's search path according to File | Set Path. Additionally, the function loadlibrary() works well with the files shrlibsample.mexw32 and shrlibsample.h in the directory matlabroot\extern\examples\shrlib

Is the dll for 32 bit code or for 64 bit code?

Your reference to success with shrlibsample.mexw32 suggests you are using 32 bit MATLAB, but please confirm that.

I'm not sure the .DLL is for 32bit or 64bit, but it was just the files provided by the HP more than 10 years ago for matlab. may be for 32bit ?
