<DIV>Hi,</DIV>
<DIV> </DIV>
<DIV>Thanks for your warmly help. But it seems not because of the filename's
slashes. When i change the filename as the method your proposed, the exception
was thrown out as before. And further more, i succeed in displaying image in
Win32 console application, using both '\' and '/'. So i think the bug
lies somewhere esle.</DIV>
<DIV>Thanks again and i'll appreciate your further help!</DIV>
<DIV> </DIV>

I suspect the filename's slashes are getting escaped. It should end up
looking like c:/foo/foo.png or like "c:\\foo\\foo.png" You could use
itksys to convert these paths from the native windows style paths.
#include "itksys/SystemTools.hxx"
std::string fname = strFile
itksys::SystemTools::ConvertToUnixSlashes(fname);
if (!itksys::SystemTools::FileExists(fname.c_str()))
{
std::cerr << fname << " doesn't exist.. check again" << std::endl;
}
