How do you implement the ? help, where user clicks ? and then clicks a control for more help?

Question

I don't even know what this is called. But some Windows apps used to have a "?" near the X in upper right corner. You could click that and then click on something on the screen and get help.

Anyone know what that's called or (better) have any pointers to instructions on how to implement it?

Oh, and I'm using vb.net 2005.

Answer 1

It's called Context-sensitive help; that's about all I know.

Answer 2

In .NET you can turn it on by setting the boolean field "HelpButton" on a form control. See this link for more info. Additionally, there's an event that fires on clicking this button. Link here.

Hope that helps... Are you using .NET or something else?

Answer 3

It is called "What's This?" help.

Here is a Microsoft article on implementing it in Visual Basic. If you want another language, I hope this is enough of a pointer to get you there.
