Very Strange Thing...

[Vlatko]

I am making a kind of a notepad app(no MFC).I use this to open a file:

#include <string>
#include <fstream>
using namespace std;
....
string all,got;
ifstream in(filename); //this
while(getline(in,got))//this
{
all += got + "\r\n";//this
}
SendMessage(e,WM_SETTEXT,0,(LPARAM)all.c_str() );

The lines marked "//this" make my app 120 KB bigger.(from 36 to 156 KB)
Why is this happening?

Because you're bringing in the iostream libraries. Are you compiling as Win32 Debug by any chance? The Standard C++ Library causes the MSVC++ compiler to churn out loads of debug info.

No i am compiling as Win32 Release.As debug it is 450KB large.Can i make it smaller in some way or not.

...One check later...

It's a slight issue with the iostream libraries that MS supply - they can often make your app pretty big. Try playing around with the optimisation settings.
