[Insight-users] Image reader problem

[Charles Knox]

Thanks Bill and Niels,

I ran itkGDCMImageIOTest in debugging mode (after hard coding in some 
file names) and it runs fine!  I can step into ITK code and see the file 
names being saved.  Both ITK and my software are compiled using the 
_MBCS option (multi-byte character strings), so I don't think it's a 
problem with multi-byte characters, although am still looking at this.

Does ITK support Unicode or MBCS?  I don't know.

So, as of now, I'm stumped. 

Regards,
Charlie
