VS 2010 - Detecting Mouse / Keypress Input
Dec 5, 2011
I am creating an application that creates scripts to move a mouse and to click where a user wishes to via pre-programmed code and to also press keys where required. I have the code to move a mouse and to manually click anywhere. What I am after is to detect when a mouse button is pressed and dragged and when keys are pressed.
I see that there is the following
MouseButtons.ToString
To detect when a mouse button is pressed, and have it looping in a timer. Is there a better way to do this? I would rather not use a timer. And is there a similar routine to detect which keys are pressed?

I'm trying to detect the Printscreen keypress with the use of a timer. I can't useform1_keyup/down as the focus isn't always on the form.

I'm working on an application of which counts how many keystrokes/clicks. I'm just wondering how I would go about logging such actions. The application will be running in the background within the taskbar and when you click on anything on your computer/type anything or press any key I want it to pick up the event and log and add up, so if i click 10 times it will add 10 onto the total clicks and vicer versa on typing.

Is there any way of detecting the position where the Mouse Button is released during a Drag & Drop operation. I need to know whether the intended Drop position was not reached when the mouse button is released.

I need to create a program that can run code each time the user clicks, I can't use windows forums since its on another program. If the code can detect global mouse clicks(system wide) or only on one program it's fine.
I've done some digging and it looks like windows API can solve my problem but i really suck at using windows API and it looks like SetWindowsHookEx() can solve my problem but i don't know how to use it correctly. This is the code from Pinvoke that I modified to hopefully work for a mouse click. i'm having trouble getting this to work.
Imports System.Runtime.InteropServices
Imports System.Windows.Forms
Module Module1
Sub Main()
Dim t As New MouseHook
[Code]...

I want to make an auto log off feature, I want to detect if there is any user input, and if there isn't the user will be automatically logged off. So I want to know how to detect mouse wheel events when the form doesn't have focus.

I want to be able to detect when the user presses F10 or Ctrl+F10 outside of my program, and upon receiving the key press, it will send text to whatever they currently have selected (e.g. a text box). How can this be accomplished in the simplest way?

If my window is hidden or out of focus, how do I detect a keypress? The idea is that it just sits in the tray as an icon until a key combination is pressed and then it pops back up again.

I have two issues. The first is that I want to make a textbox scrolling similar to how credits scroll. I don't want it to move on the form, just to scrolling the text down a line/pixel. I thought I could do it with the "Lines" element, but I'm not exactly sure how to execute it.
The other problem is with my flash screen. Right now I have it set so when a button is click, it goes onto the main form. I don't want to use the button but rather have it so if Enter is pressed at any time, it'll go to the main form. All the solutions I've tried to use involve the "e.Keycode" code, but for some reason its unavailable.

I'm trying to set up a timer that counts up to ten and starts/resets when the left mouse button is clicked (anywhere on the screen even when the application is in the background). I'm struggling to find a code that suggests it is possible and now I am starting to wonder even if it is possible in VB?

I try to detect when the mouse is over a curve in zedgraph, I am capable of doing it if the mouse is over a point of the curve, but the problem is when the curve has no points in that region,let me show you an example:
Curve is defined by 2 points: [X=0;Y=10] -- [X=1000;Y=10]
If mouse is at point [X=500;Y=10] it is over the curve, but not over any point so i cannot detect it.Is there any event which gets fired when mouse is over line but not necessarily over a point?

I need to know a way to detect if the mouse has been clicked anywhere on the screen. So as long the program I am making is open when the user clicks my program needs to do something. Please let me know as soon as possible if this is possible and how you do it.

The script should detect which key is pressed from the keyboard, including F keys; the script should start and when the user presses F2 should print something like "you pressed F2", when the user presses "A" should print "you pressed A", and so on

The GetAsyncKeyState Api does'nt recognizes the mouse wheel rotation, I see.Is there way to control the mouse wheel rotation (always, not only when the pointer is over a form of mine) with a simple API, without to Hook the mouse?

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 don't know if this is really possible, the program can not use a mouse or anything that requires the use of the tab key (this would be considered a use of the mouse), is there a way to still add input into textboxes and hit buttons, kinda like the letter "q" takes the place of the tab button and letter "W" takes the place of the enter button, or this can't be done?

I'm using the following code for to send mouse or keyboard input to windows:
Imports System.Runtime.InteropServices
Mouse:
mouse_event(mouseclickdown, 0, 0, 0, 0)
mouse_event(mouseclickup, 0, 0, 0, 0)
[Code].....
These work perfectly in the Windows/Desktop, but when I tried to use these in Games, the input from the program didn't seem to register, or rather registered in the background on the Desktop.

I would like to use raw input on mouse mischief to send emulated input as if it is coming from the mouse device.
For instance, fake mouse 1's cursor position on screen and mouse click are sent to the application inpdendtly from the system mouse or default mouse that is actually plugged into the computer.
Yes, as far as i know mouse mischief has to accept WM_INPUT so these messages because as far as i know theirs not another windows api that does this and ondevicearrival can be sent onto the application producing my desired result of creating the mouse pointer.
Anyone have any code i can try because this code is really a WM_INPUT with raw input version of kinect mouse project which i have permission to modify straight up.
