I can't use DrawText()

I am trying to drwa some text using GDI on c++

It happens that I have a class that has a method to return the status and I want to draw it

The status is a std::string!

So here is what I have so far:

        RECT status = RECT();
        status.left = rcClient.right-200;
        status.left = rcClient.left;
        status.top = rcClient.top;
        status.bottom = rcClient.bottom;

        DrawTextW(hdc, game->GetStatus().c_str(), 1, status, 0);

The errors I have are:

error C2664: 'FormatMessageW' : cannot convert parameter 5 from 'LPWSTR' to 'char *'687 damas
error C2664: 'FormatMessageW' : cannot convert parameter 5 from 'wchar_t *' to 'char *'damas
error C2664: 'DrawTextW' : cannot convert parameter 2 from 'const char *' to 'LPCWSTR'

I can't find a way to solve this... can someone help me out?

A std::string uses chars, but DrawTextW is expecting wide chars (WCHARs, which are identical to wchar_ts).

You can call DrawTextA explicitly with your string. It will make a copy of your string using wide characters and pass it on to DrawTextW.

DrawTextA(hdc, game->GetStatus().c_str(), 1, &status, 0);

(Also note that it takes a pointer to the RECT, so you need the & as well.)
