使用Qt创建器时出现C2440错误，但使用VS2010 Express可以正常运行代码

Question

I have these lines of code in a command line project in VS2010 c++.

        TCHAR          name[30];
        LPTSTR         pname=&name[0];
        std::wstring   OutNumber;
        pname = &name[0];
        GetWindowText(hGameNumber,pname,30);

works fine without problems. No I'm using the same lines in a Qt widget base application using Qt Creator. When compiling it I get the error:

"error: C2440: 'initializing' : cannot convert from 'TCHAR *' to 'LPTSTR' Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast"

Thanks for any help, Lumpi

Answer 1

cast, as in LPTSTR pname = reinterpret_cast<LPTSTR>(&name[0]);

and all will be well. also remove the line that reads pname = &name[0]; right after you create the std::wstring object.
