const GLubyte *szExtensions = glGetString(GL_EXTENSIONS);
char m[1000];
sprintf(m, "%s", (char *)szExtensions);
MessageBox(NULL, m, "Error", MB_OK | MB_TOPMOST);
PLEASE HELP

char* Buffer = (char*)malloc(strlen((char*)glGetString(GL_EXTENSIONS))+1);strcpy(Buffer, (char*)glGetString(GL_EXTENSIONS));MessageBox(NULL, Buffer, "Error", MB_OK);free(Buffer);
Looks like an error occured. E.g. if you call glGetString between glBegin()/glEnd(), it will return 0. Use glGetError() to retrieve the error code.

const GLubyte *szExtensions = glGetString(GL_EXTENSIONS);char m[1000];sprintf(m, "%s", (char *)szExtensions);MessageBox(NULL, m, "Error", MB_OK | MB_TOPMOST);I'd like to add that 1000 characters is probably not enough to fit every extension, except on older graphics cards. If you're using C, you should use strlen, malloc and strncpy to make m the proper size, if you use C++ use std::string...
