  I'm going to assume you are using Visual C++ 2005 Beta-2
  
  Here are the steps I use:
  
  Open the IDE
  
  Click on File.New.Project
  
  Select Win32 Console Application and give it a name: say "Hello"
  
  Click OK and then click Finish
  
  Once the Solution Explorer appears vlick on the main source file: if you named the Solution "Hello" this file will be called hello.cpp. The source file should appear something like what is shown below:
  
  

  // First.cpp : Defines the entry point for the console application.
  //
  #include "stdafx.h"

  int _tmain(int argc, _TCHAR* argv[])
  {
      return 0;
  }
  
  Add the following source code to the _tmain function (don't worry that it is _tmain and not main).
  
  std::cout << "Hello World" << std::endl;
  
  Now open the stdafx.h file and add the following line
  
  #include <iostream>
  
  The build your project. It should build cleanly and you will then be able to execute the resulting application.

  This program is not valid. You got build errors, so no executable program was created. You need to fix the build errors.
  
  The include needs to be:
  #include <iostream>
  
  And the compiler error (in the output window) should have indicated you that the header "isotream.h"does not exist.

  Thanks Mr. Caves,
  
  but now im running into a different problem when i executed the program, the output window comes and goes really fast, it does not say on. it like blinks on then it closes.
  
  how can i fix that

  Try setting a breakpoint in the main function: this should stop the execution and let you see what is happening.

  If you in fact built a console application as Mr. Caves suggested the console window is opening when you launch your application then closing the console window when the end of your application flow is reached.
  
  Something simple to pause your application while it is executing will leave the window open long enough for you to see the contents of the window.
  
  Try adding the following code inside your tmain just before the closing bracket. The last three lines of your tmain should be:
  
  

  // pause after executing console application
  fprintf( stdout, "\n\nHit any key to exit...\n");
  fgetchar();
  return 0;

  The first message is because you have tried to run the program before you have compiled it.
  
  The second message is because the compilation failed and the project system is suggesting that you might want to execute the program which resulted from the last successful compilation.
  
  The third message is because there wasn't a previously successful compilation and so there is no program to execute.
  
  You should take a look at the build errors that were generated, fix them and then try to rebuild the program.
