C# - Detect Mouse Click Outside Form

[akowald]

There's another topic like this but the code posted is in VB.NET.

Well I need some help detecting mouse clicks outside the form. An event
handler would be great but I can work with anything.

Thanks in advance,

Alex

You can utilize windows hooks in order to detect all mouse clicks...

His code was written in VS 2003 and I'm using VS 2005. I implemented
his code into my project and it threw an exception...

System.Exception was unhandled

For the sake of other people that have the same as me I'll post this:

This is how to get the above code working under VS 2005:

(this is from the comments of the codeproject post)

You just need to UNCHECK the check box in the project properties that
says:
"Enable visual studio hosting process"

In the menu:

Project -> Project properties... -> Debug -> Enable the visual studio
hosting process
