This article demonstrates the development of screen saver using Win32 SDK. This article is very simple. It has 3 routines which are called by Windows 95 during screen saver activation. The first one is where we set up our timer and display a series of bitmaps one by one every 7 seconds. The source code is provided along with comments.

It is very simple. It explains how to load the bitmap BMP file format into the memory and how to manipulate them using the Win32 APIs. I have used straightforward method to allocate and display the bitmaps to the screen. Kindly go through them and provide me with your questions and suggestions.

To use the screen saver first create a folder called C:\Screen. Then put all your wonderful bitmaps in this folder. Then activate the Bitmap Screen Saver using control panel. First you must have the SCREEN.SCR file in the Windows folder. Then use Control Panel to change the Display settings.

I have a bunch of software utilities in my web site at http://members.xoom.com/vinoj/ which can be visited at your liesure and software can be downloaded. To get the source codes write to my e-mail address. Here I have provided complete source code for my screen saver.
