Try ShellExecute:

HINSTANCE H;

H = ShellExecute(
    this,
    (LPCTSTR) "print",
    (LPCTSTR) "c:\foldername\program_name",
    (LPCTSTR) "c:\anotherfolder\anotherfile.pdf",
    (LPCTSTR) "c:\",
    SW_NORMAL
);

You shouldn't need to cast it there, also, you're casting to an unsafe type, use:

HINSTANCE H;

H = ShellExecute(
    this,
    _T("print"),
    _T("c:\\foldername\\program_name"),
    _T("c:\\anotherfolder\\anotherfile.pdf"),
    _T("c:\\"),
    SW_NORMAL
);

LPCTSTR is const TCHAR*, where TCHAR is either char or wchar_t depending on the definition of UNICODE.

_T will evaluate to a wide string or an ANSI string dependent on UNICODE.

Mind the double \! Since \ is the escape character, i.e. it has a special meaning, you need to escape it to get the real character: \\.

I used LPCSTR since they were all constants. Which is alright in this instance.

I did not escape the \ to \\, which is not alright.

Mm-hmm, but they don't match the datatype (TCHAR).
