API Programming Series #4 - Introduction

sreejath

Introduction

This article deals with hiding an Application from the Windows task list. As developers, we often feel the need to run certain processes in the background that provide support services to another application. In such cases it is desirable that this support application doesn't show up in the Alt-Ctrl-Del list (also called the "hit-list") as this may enable the user to kill it causing an application/system crash. In this article we'll discuss how to achieve this in a VB application using API programming.

Note 1: This contents of this article applies to Win9x/Me based machines only. This will NOT work on WinNT/2k based machines.

Note 2: If you are new to Win32 API Programming using Visual Basic, then please go through my introductory Articles to get a basic understanding of what Win32 API is and how you can use it from within Visual basic. Article 1 deals with the concept of Win32 API Programming as applied to Visual Basic and Article 2 explains how to access and use the Win32 API  from within VB.

    Primarily, I wanted to focus on the API call I...
