Interface And Graphics :: Mouse Control - Move The Mouse To A Given Pixel Position (x, Y) And Cause A Click

Oct 6, 2008

Apologies as this has probably been answered a million different times a million different ways already. I'm trying to control the mouse. I wish to move the mouse to a given pixel position (x, y) and cause a click. I don't want this to be limited within a form, as I want to control another application. I'm using VB 2005.

Fastest Pixel Monitor Method?

Apr 19, 2012

I have a pixel I want to monitor for change. For example, first it is white, and suddenly it is black, and then changes back to white. My method is not fast enough to get this change.any changes I call the function below to get the original color of the pixel. Then I have a timer that runs every 1 ms to take the color of the pixel, and if it's not equal to original color; do something. For example counts the time the pixel has changed. However, this function does not run fast enough. Is there any faster methods to check the pixel? The function returns an ARGB code of the pixel color.[code]....

Detect Pixel Color Change?

Aug 21, 2010

I'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.

Scan Program To Detect Pixel Color Change?

Sep 14, 2011

The 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)

Program To Detect Change In Selected Pixel On Screen - Memory Leak

Mar 21, 2011

I 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

Add The Mouse When Capturing The Screen Or Monitor?

Jul 18, 2012

I'm just wondering if it's possible to add the mouse when capturing the screen or monitor in vb.net?

because I'm doing a project that would record the screen and I'm actually successfull doing that by capturing the screen and include it in a timer, but my only problem is the mouse or the cursor isn't showing.

below is my sample code.
Dim ScreenSize As Size = New Size(TotalScreenWitdh, MonitorHeightArray(0))
Dim BMP As New Bitmap(TotalScreenWitdh, MonitorHeightArray(0))

VS 2008 - Display The Color Of The Current Pixel Under The Mouse Pointer

Aug 6, 2009

I want to make a small application for my web designing needs that will display the color of the current pixel under the mouse pointer. I need this to work on the entire screen (no matter what form/application is in focus) and it needs to update in real time.

I'm not worried about the math or working with coordinates, but I don't know (and can't find) anything that might get the color of the pixel under the cursor on any form. I've found a small number of VB6 examples, but I'm with .NET 2008. Does anyone know of a method or anything (DLL even >.<)

Monitor The Current Position Of The Mouse Cursor?

Apr 21, 2009

I'm trying to create a hook to monitor the current position of the mouse cursor. Nothing important, I just need to count some pixels during interface design and wanted to learn how to create a hook, so I decided to go for a hard way instead of a sane way.

I've found example code which declares the following function:

<DllImport("User32.dll", CharSet:=CharSet.Auto, _
CallingConvention:=CallingConvention.StdCall)> _
Public Overloads Shared Function SetWindowsHookEx _

[Code].....

But Appdomain.GetCurrentThreadID generates the warning: "'Public Shared Function GetCurrentThreadId() As Integer' is obsolete: 'AppDomain.GetCurrentThreadId has been deprecated because it does not provide a stable Id when managed threads are running on fibers (aka lightweight threads). To get a stable identifier for a managed thread, use the ManagedThreadId property on Thread."

I've tried using ManagedThreadID, but that doesn't work. The thread ID returned seems to be the logical thread ID of the thread, as it runs in the .net runtime, rather than the Win32 thread identifier.

Calling the function ith AppDomain.GetCurrentThreadID works, but I really would like to have a "stable identifier" for my thread.

Can someone explain to me whether it is possible to use ManagedThreadID in this context (I assume not) and, if not, the things I need to avoid in order to stop the AppDomain.CurrentThreadID from becoming "unstable"?

WPF Detect Mouse Move?

Jan 20, 2010

Well im trying to make my own basic Slider control just so i can learn abit how to interact with the mouse...

so far i have this:

vb.net:
Private Sub Rectangle_MouseMove(ByVal sender as Object, ByVal e as System.Windows.Input.MouseEventArgs)

[Code]....

so this works while the mouse is on the rectangle.. but if we look how the slider behaves its not the same you click and hold the mouse down and can drag it any where even outside of the window and it still updates its position..
