Aug 21, 2010I'm trying to figure out some simple code to detect when a single pixel changes color at a location I choose -anywhere- on the screen (ex. 100,100). Maybe with just a msgbox popup when it changes.
The visual basic program will just be hidden and running in the background.
I should be able program the rest of the program around it, I just need the detection part. That is where I am stumped.
Detect And Change Screen Resolution
Jul 22, 2009How to create a program that detects the screen resolution and change it to 1280x800 or 1024x768? What are the computer requirements to support each of these resolutions. (I don't want for the program to request the user as programs do this especially in Windows Vista, because my program will be created for Windows Vista).
View 8 RepliesScan Program To Detect Pixel Color Change?
Sep 14, 2011The purpose of the code below is to scan a program of mine to detect a pixel color change. It loops through until a change is detected. It works fine for about 10-15 seconds and then I get an ArgumentException was unhandled error. So far this has happened on two different lines at separate times...
Image = New Bitmap(Rec.Right - Rec.Left, Rec.Bottom - Rec.Top)
Detect Mouse In User Control - Border Color Change?
Dec 28, 2010I've got a couple of instances of a user control on a flowlayoutpanel. The user control has got a couple of controls on it, and very little / almost none of the control's original space is visible. I need to know when the mouse is inside the usercontrol. What then happens is that the border color changes (of a control in the user control), and when it leaves the control, it changes back to original state.
I tried the following:
Private Sub ctrDashboardWidgetFrame_MouseEnter(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.MouseEnter
Try
ShowControls()
Catch ex As Exception
[Code] .....
And it works, but it only works when you move over the original visible space of the user control, and doesn't work when you move over the child controls inside the user control. How I'll be able to achieve this to also work while the user is inside the full user control and not just it's visible space?

Program To Detect Change In Selected Pixel On Screen - Memory Leak
Mar 21, 2011I am fairly new to visual basic and have written this program to detect a change in a selected pixel on the screen. When the pixel changes, a sound plays every x seconds. It works fine but after a few hours of operation a possible memory leak causes it to either crash the program or the PC. I have watched the process and I can see 4k added to it every 4 seconds or so. Where this memory leak is coming from?
Here is the code:
Public Class Main
Public pointx As Long
Public pointy As Long
Public areaselected As Integer
Public TimeToPause, SecondTimer, changefound As Integer

View 4 RepliesWay For Service To Detect When Logon Screen Is Present And When It's Gone?
May 25, 2010I am planning on creating a service that measures the bootup time for a computer. It would go something like this:
1. Service starts and waits for CTRL+ALT+DEL screen
2. Timer starts when logon screen appears
3. User logs in and timer stops
4. Service waits for process X to start
5. Process X starts and service gets System.Environment.TickCount
6. Service subtracts step 3 ticks from tickcount
The reason for the logon screen timer is I don't want to measure if the user booted up and went for coffee or something and shows up 20 mins later to log in. Is there any way for the service to detect when the logon screen is present and when it's gone?
