Answer 1

Answer to your question:

string name = 'stackoverflow';

MessageBox("name is: "+name , "Msg title", MB_OK | MB_ICONQUESTION);

do in same way for others.

Answer 2

This is the only one that worked for me:

std::string myString = "x = ";
int width = 1024;
myString += std::to_string(width);

LPWSTR ws = new wchar_t[myString.size() + 1];
copy(myString.begin(), myString.end(), ws);
ws[myString.size()] = 0; // zero at the end

MessageBox(NULL, ws, L"Windows Tutorial", MB_ICONEXCLAMATION | MB_OK);

It's not good to see people still messing with buffers. That was unnecessary in 1998, and definitely today.

std::string name = "stackoverflow";

MessageBox(hWnd, ("name is: "+name).c_str(), "Msg title", MB_OK | MB_ICONQUESTION);

If you're using Unicode (which makes sense in the 21st century)

std::wstring name = L"stackoverflow";

MessageBox(hWnd, (L"name is: "+name).c_str(), L"Msg title", MB_OK | MB_ICONQUESTION);
