Mouse Movements To Fast To Fire Events Accurately?
Jul 8, 2011
I'm working on a custom scroll bar. When dragging the slider, things work smoothing with what I have... that is if the users movements are smooth and slow-ish. When moving quickly the mouse move event doesn't seem to fire as accurately as I had hoped.. I attempted using the up and down buttons enter event for re positioning or "resetting" the slider whenragging is activated but still those events don't even fire when the mouse move event is firing. So I believe I hit a barrier of my .Net knowledge and hope someone here knows a way around this little issue.

I have few questions regarding the cursor movement. As you all know, moving the cursor is as easy as cursor.pos = new point etc... but that jumps your mouse to the new location. Anyway, here are my questions.
1.How to simulate mouse movements to look like humans'? I want my cursor not to jump around but move/ flow from point to point.
2. How do you click a point/place without moving your cursor? I know this is possible, just not sure how people do it. For example, say my mspaint. exe is minimized. I want to to random click at a coordinate in the mspaint.exe without actually having to move my original cursor.

I am working on mouse recorder and I got it where it will record and playback the mouse movement by using 2 simple listbox and some codes. But now I am stuck on how to get it to record the clicks and also playback that as well. I was wondering if I could just use another list box to store the clicks in it? But I am sure I got to do something more extreme.

I am trying to create an application that logs off a computer. I want it to check for mouse movement. If the mouse hasn't been moved in a certain amount of time then log off. I created an application for a form that if the mouse isn't moved in the form in 5 seconds the application closes. The reason I am trying to create this is because I work for the board of education and we have a problem with the teachers not logging off. The students get on there computers and mess stuff up. So my questions are:
1.) Is there a way to record mouse movements in windows instead of just the form? tutorials/info?
2.) Is there a way to execute a command like you would in a command prompt? For example if you type in shutdown -r it will restart the computer. tutorials/info?
3.) I do not want an interface for this just an icon in the task bar and for it to start on bootup. tutorials/info? When it reaches the time I want it to pop up with a form and say logging off in however many seconds and then logoff.

I display a Chart with several graphic lines on it. What I want to do is draw a line (using the mouse) overtop or below the chart such that it can be seen on the chart. The mouse line draw code is below. What is required is either make
the line always be on top or make the chart transparent. I don't know how to do either and I don't know if it is possible in Visual Basic 2010 as it was in VB2.

I have a very simple app working well, problem is that it does not close properly. If the user uses the little "X" to close it, it still remains running, just becomes invisible. The X does not fire the closing/closed events..All I can figure out is that to get it to properly close I need to use "Me.Close()" with a button or menu item.I could remove the standard X and force them to use my own close button but that is rather silly..

I'm currently debugging a form that sets a flag when the mouse button is pressed, then clears the flag when the mouse button is released. As long as the mouse button is pressed, the user can move the mouse around and a few things happen depending on where they move. One of the things that happens is that a timer starts, or stops, and a few things change color depending on the mouse position. The timer starts when it should, then stops when it should, but once stopped, it is not re-starting when it should. I can verify that MouseMove events are getting through, because coloring changes as I move the mouse, as it should. This would be a simple thing to debug...except that it requires the darn mouse button to be down, and it uses the mouse move event. Anybody who has put a breakpoint in a mouse move event handler knows the issue: There are THOUSANDS of them. Worse yet, since the mouse button is necessary for switching to the IDE, as well as setting a breakpoint (technically, a keyboard shortcut could do this if I could shift focus), I can't wait for the problem to happen, then switch to the IDE and set a breakpoint to see what is happening then.Does anybody have any tips or techniques for debugging in mouse move events when the mouse button is down and has to stay that way? As it is, I'm going to have to write some funky code into the method just so that I have a place to get a breakpoint when I need it without breaking on every one of the mouse move events.

I recently developed a software called MouseMe, which basically records mouse movement and mouse press events. The software itself is in BETA, and I am looking for some testers to have a go at my program.

I have this issue where I'm trying to generate HTML to display on the page that is coming from the database in form of a template that has different curly brackets that get replaced with dynamic content at run time. For example curly bracket {Content} gets replaced with a few checkboxlists, radiobuttonlists, textboxes and a submit button. The way I'm doing this is by creating controls dynamically and rendering them as string and then outputting that string to the browser. But what this does is, it doesn't recognise the events assigned to the controls when they are generated. I may be taking a wrong approach to the issue, but I don't really see how else this can be achieved. I have put up some sample code below to show what I'm trying to achieve.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

I know that by clicking before an object is finished moving, causes the object to move again, prematurely. I have tried using "If Timer2.Enabled = False Then move. This does not work. Is there another way to disable either the mouse or program execution until the animation objects are finished moving?

I've got a research application that is hosting a webbrowser control and I'm implementing a feature that allows the user to select text from a web page and drag it to various research note fields. The issue I have is the dragenter and dragdrop events continue after the initial drop, inserting the text multiple times. Here's the test case on my box and the result.
Select Text in Browser Drag to Text Box Drop Text What happens is after the drop event is fired and the text inserted to the drop target, when you move the mouse after dropping the text, the drag enter event is fired, followed by the dragdrop event, then another dragenter and dragdrop. So, selected text such as "Selected Text" becomes "Selected TextSelected TextSelected Text".
Note: The dragenter event is properly raised once when the mouse enters the textbox, however the mouse does not have to leave the textbox after the dragdrop event fires. i thought there was something wrong with my application so I created a simple test app, containing a Webbrowser and a multi-line text box. This test app generates the same results and the code is below. This is the first time, I've implemented
drag and drop operations and I followed the guidelines noted in this MSDN article. While I did what the article suggests, I'm thinking I need to note the event was handled somewhere.

I have a simple program. It has a "Start" and an "Exit" button. When the "START" button is hit, I change the text on the exit button to read "STOP PROCESSING". Then I go into my processing loop. When the "STOP PROCESSING" button is clicked the first time, the program simply ignores it. When I click it the SECOND time, it gets control. I know this because I put a breakpoint in at the start of the subroutine.What could I possibly be doing to quash the firing the first time?

I have a program that reads data from a scanner via the serial port.This program works fine on Windows XP.We have a terminal server set up running Windows Server 2008.I run HyperTerminal on our test terminal, it connects and reads the scanner data fine through COM1.I run my app on that same test terminal and get nothing when I scan.My app connects to COM1 without errors and disconnects without errors.BUT, the DataRecieved event is NEVER getting fired.Neither is the ErrorReceived event.I have played with the Handshaking, with the RecievedBytesThreshhold and pretty much every setup setting I found.Set it up exactly like the settings on Hyperterminal.I have even tried starting a timer on a different thread to call ReadByte every second to try to KICK this thing into doing SOMETHING.Nothing has worked.
I have been trying to fix this for an entire day now.Added events to my class trying to see EVERYTHING that is going on. All I know is, it connects to the port and it disconnects from the port correctly but nothing happens in between.No data when I scan.No event fired at all between connecting to and disconnecting from the port.I have also downloaded other's simple serial communications applications.Nothing in .NET works.[code]

I need to fire an event when the mouse enters a panel with the mouse button already down. It seems the standard mouse enter, mouse move, etc events don't fire when the mouse is already down. With test code i'm using, all of the events fire when the mouse button is up, none fire when the mouse button is down.
edit...here is my test code..

I am using about 5 different filesystemwatcher routines total. I am using the following
filewatch.NotifyFilter = NotifyFilters.CreationTime Or NotifyFilters.LastWrite
AddHandler filewatch.Created, AddressOf addfile
AddHandler filewatch.Changed, AddressOf addfile
filewatch.EnableRaisingEvents = True
However, there is one problem with it... whenever I open a file and change stuff, then close it without saving the changes, the events still fire. I am opening excel workbooks in code, then use xlsWB.Close(SaveChanges:=False) to close them, and the event still fires, where the file isn't really changed so it should not fire.

Does anyone have a trick to catch when the mouse is over a listview column header ? As you know there is no native handler that would fire such event...
I have build a small routine that will be able to tell over which column the mouse actually is, the problem remains in which event to put it..

I created a control that has picture box control docked within it. This control allows me to "animate" the image by swapping them out by setting the interval to swap them at. I want to use this control kind of like an animated icon within a application, but because the picture box is docked, the control I created won't respond to the events, MouseHover specifically.

I have an object that is defined as a global variable based on custom class. Within that class I have an event that gets fired a certain intervals. These events are fired on the same thread as where the object is declared. How do I create a global object, but have the events within that object fire on a separate thread?

I am working on a project which will be installed in Embedded pc which won't have mouse and keyboard. Works with touch screen. I have an option in my software to make calls.I need to have an option like Push to talk. When need to talk they need to push the button and when they release they can't talk. Something like walkie talkie concept. The embedded pc where my software will be installed will have touch screen. How can I do this??
I tried to write my code in button click event and when they take out the mouse from the button, I am stopping voice. But, that is not I want. I need to push to talk and release after talk.
