DWORD is no standard C++ datatype, it is Microsoft specific, but according doe "MSDN":http://msdn.microsoft.com/en-us/library/cc230318(v=prot.20).aspx it isdefined as:
unsingend long, so you can:

qstr = QString::number(dw);

MuldeR

Or if you need a plain C string:

@DWORD dw = 42;
char str[128];
snprintf(str, 128, "%u", dw)@

Or the C++ way:

@DWORD dw = 42;
std::stringstream sstr;
sstr << dw;
std::string str = sstr.str();@

on your line 2 and 4 i get the following errors :(

main.cpp:1699: error: C2079: 'sstr' uses undefined class 'std::basic_stringstream<_Elem,_Traits,_Alloc>'
with
[
_Elem=char,
_Traits=std::char_traits<char>,
_Alloc=std::allocator<char>
]

main.cpp:1701: error: C2228: left of '.str' must have class/struct/union
type is 'int'

You've got some "include" missing.
