sstream and LPSTR

I need to convert a str value from a sstream to LPSTR but I have no clue how.

Hers my code:

Code:

---

        float currenttime = (float)GetTickCount();
        float deltatime = currenttime - lasttime * 0.001f;
        outs << deltatime;
        LPSTR test = outs.str();  //Error line
        SetWindowText(eng.window, test);

---

The error says:

error C2440: 'initializing' : cannot convert from 'std::basic_ostringstream<_Elem,_Traits,_Alloc>::_ Mystr' to 'LPSTR'

a couple ways to solve your problem - neither use LPSTR

Code:

---

                std::string test = outs.str(); 
                SetWindowText(eng.window, test.c_str());
  OR
                SetWindowText(eng.window, outs.str().c_str());

---

str().c_str() will return a const char*, which is what LPCSTR is. This is different than LPSTR, which is just a char*.

In this case it should be ok, since SetWindowText actually takes an LPCTSTR (which is just an LPCSTR for your program if you don't use Unicode).
