how to write a new line?

[chiwing]

how will u write below to a empty file ?

<trustInfo xmlns="urn:schemas-microsoft-com:asm.v3">
<security>
<requestedPrivileges>
<requestedExecutionLevel level="asInvoker" uiAccess="false"></requestedExecutionLevel>
</requestedPrivileges>
</security>
</trustInfo>

string write_stuff = "
<trustInfo xmlns="urn:schemas-microsoft-com:asm.v3">
    <security>
      <requestedPrivileges>
        <requestedExecutionLevel level="asInvoker" uiAccess="false"></requestedExecutionLevel>
      </requestedPrivileges>
    </security>
  </trustInfo>
"
WriteFile(handle, write_stuff, Bytes_that_need_to_write, BytesWritten, NULL);

does it OK? or need to write a new line by /n (C syntax) ?

You need to 'escape' the newline literals. You also need to 'escape' the double quotes. Also, don't forget your statement terminators (semicolons).

string write_stuff = "\
<trustInfo xmlns=\"urn:schemas-microsoft-com:asm.v3\">\
    <security>\
      <requestedPrivileges>\
        <requestedExecutionLevel level=\"asInvoker\" uiAccess=\"false\"></requestedExecutionLevel>\
      </requestedPrivileges>\
    </security>\
  </trustInfo>\
";
WriteFile(handle, write_stuff, Bytes_that_need_to_write, BytesWritten, NULL);

Hope this helps.

i find a usfel example just before

/n is before the line need to output~ ~

include <iostream>

size_t getPtrSize( char *ptr )
{
   return sizeof( ptr );
}

using namespace std;

int main()
{
   char szHello[] = "Hello, world!";

   cout  << "The size of a char is: "
         << sizeof( char )
         << "\nThe length of " << szHello << " is: "
         << sizeof szHello
         << "\nThe size of the pointer is "
         << getPtrSize( szHello ) << endl;
}
