Detecting Color Change?
Dec 19, 2009
I want to be able to isolate an area of my desktop (similar to a screen capture snip) and evaluate if it is changing. In this particalr case it is an appliacation I have (not mine) that flashes an icon upon completion
What I want to do is make a small app that will detect change when I am away and perhaps perform a specific action (the action is not relevant really - i can take care of that) Again,this is NOT hugely important, but if someone has an idea or has seen an app that does this, it would be useful for me...
I put this in the VB.NET forum because I write 75% of my code in VB.... so I chose this instead of a general area !!

I have the following
VB.NET
Private fsw As FileSystemWatcher
Public Sub WatchFiles(ByVal tblMappings As DataSet)

I've been attempting to determine if a notebook's lid has been closed when the power setting is set to "Do Nothing."I was able to get this to work by trapping the WM_POWERBROADCAST message, but it would only work when the computer when to sleep. I've tested this on many different notebooks and the results vary. Even when changing the power settings correctly, the results were fairly inconsistent.So I posted this question in General Developer and penegate offered a possible solution.[code] I'm thinking that maybe the message I'm trapping isn't correct, but I'm not 100% sure. When I Google that message, nothing comes up. Two links appear. The one on VBF and some German site. Nothing's on MSDN.

I've been using 'GetScrollInfo' to find the position of the scrollbar on a ListView and I can detect when it hits the bottom of the list. Is there anyway I can raise an event when the scrollbar changes? At the moment I have it working by using a timer but I would rather if possible create an event to fire my routine.
