Monitor TaskBar Protection

[LJ]

The original code below was created by who I do not know, but let me say they are a genius. I modified their code for a recent project I completed that monitors the task bar and if an instance of the Internet Explorer browser is opened, it immediately closes it. This technique can also be used for software protection such as closing the program Paint (which is often used to capture/rip another programs screen images) if its opened while the program is running.

Paste the code in, then use the command: RefreshList() inside your Repeat/Window event loop.

It doesn't close any IE windows for me (W2K Pro)...

It works on Windows 98, and Windows XP. I created some more detailed code for you, tried to clean it up a bit. This will open a browser control, but while running will close Internet Explorer if it's opened. Change the URL "bisect.ldj" to be an .htm web page of your choice (make sure the .html page is in the same local directory as your PB project file). After your web page is displayed, click on Start, Programs, and try to open the Internet Explorer browser, it should blink for a second and then automatically close.

EDITED: I know I said this tip works, but I just tried it again today because
I wanted to see if I could stop other windows, but the tip no longer works.
I can open new IE instances even when following the above instructions.
Don't know why it worked before. Using Win 2K Pro.
