RE: FW: [Dev-C++] Win32 Shell API

[Per W. <pw...@ia...>]

That is your problem.

You simply can not use strcat to concatenate a "\0" since it breaks at the
\0 in the string.

p = SrcPath;
strcpy(p,LP4);
p += strlen(p)+1; // skip # of inserted chars + the '\0';
strcpy(p,SFA);
p += strlen(p)+1; // "-
strcpy(p,"");     // just writes the final '\0'

And of course, you can not use std::cout to emit a char* or char[] that
contains '\0' in the middle...
