Answer 1

Create a temporary buffer to store your string in and use sprintf, change the formatting depending on your variable type. For your first example the following should work:

 char buff[100];
 string name = "stackoverflow";
 sprintf_s(buff, "name is:%s", name.c_str());
 cout << buff;

Then call message box with buff as the string argument

MessageBox(hWnd, buff, "Msg title", MB_OK | MB_ICONQUESTION);

for an int change to:

int d = 3;
sprintf_s(buff, "name is:%d",d);
