Hi list:
I am in the process of using boost::algorithm::replace_all with the
following tuple:
Boost::tuple<DWORD, boost::filesystem::wpath>
If I use the code below:
                std::wstring temp1, temp2, temp3;
temp1 =ProcInfo.get<1>().string();
temp2 =ProcInfo.get<1>().filename();
temp3 =L"dolapi.dll";
boost::algorithm::replace_all(temp1, temp2, temp3);
The code compiles fine, How ever if I use:
boost::algorithm::replace_all(ProcInfo.get<1>().string(),
ProcInfo.get<1>().filename(), L"dolapi.dll");
Compiling...

Using visual c++ 2008 on a windows xp box, not that this (the o/s at
least) matters.
How can I avoid creating temporary variables in this case?
Any help appreciated.
Sean.
