Is it possible to set text in a screensaver? I'm wondering how then :) ^^ /code glTranslatef(-1.0f,1.0f,-4.0f); glColor3f(0.0f,1.0f,1.0f); glRasterPos2f(-0.25f, -0.52f); glprint("wwHHAAAszzzAAAAA"); /code Glprint doesn't work, More code :) #include <windows.h> #include <scrnsave.h> #include <GL/gl.h> #include <GL/glu.h> #include "resource.h" #include <stdio.h> // Header File For Standard Input/Output #include <iostream> #include <string> #include <time.h> #include <math.h> // Header File For Windows Math Library #include <stdio.h> // Header File For Standard Input/Output #include <stdarg.h> // Header File For Variable Argument Routines //get rid of these warnings: //truncation from const double to float //conversion from double to float #pragma warning(disable: 4305 4244) #define TIMER 1 void InitGL(HWND hWnd, HDC & hDC, HGLRC & hRC);
