I'm making a craps game, and I have a "Craps Table" image in a PictureBox Control.
I've made a MouseClick event handler for the PictureBox to check what region was selected by the user, and add a bet to that "Part of the Craps Table" when clicked.
Everything works great, except if I click the region very quickly, the event fires only once for every two clicks (Approx).
I've searched everywhere, and not quite sure what I'm doing wrong. I thought at first it might be a graphics problem, but I've ruled just about everything out, and I'm thinking that the event simply isn't firing properly at high click speeds, I have to pause for half a second between clicks for it to fire.
Thanks for any advice..
Also guessing, Try MouseDown instead of MouseClick...
Another thing to check: If your app is high-cpu intensive, and the UI thread is mostly busy, the mouse events will arrive late.
My guess is that by clicking very quickly, you're triggering the doubleclick event instead of click

Is it possible to remove the limit for the Mouse Click speed in C#?
Im trying to make a Click Game Programm. You have 15 seconds time to click on a Panel as fast as you can. Every click is a Point.
The Problem is... As example, when i click 10 times per second, I only get 5-6 Points per seconds and so I can't click as fast as I can.
Has somebody an idea to bypass this?
Thanks
When you subscribe to the Click event, you will not see second clicks that occur in the doubleclick treshold, those are propagated to the DoubleClick event handler.
If you want to register clicks and bypass double click detection, subscribe to the MouseDown event instead.
I have the following event handler for a NotifyIcon within a WPF application using Forms integration:
void MyNotifyIcon_MouseDown(Object sender, System.Windows.Forms.MouseEventArgs e)
{
ShowSettingsWindow();
}
However, e.Location = {X=0,Y=0} always. Is there a way to make this work?
Update
Oddly enough, people have voted to close this question and have downvoted it. However, its clearly not working and simple enough to create a new NotifyIcon inside of a WPF application's App.xaml.cs file and try it out for yourselves.
Update
As Hans pointed out, this is by design. It still doesn't answer the question of what possible workarounds are. Furthermore, this is a bad design, because:
This event occurs on a MouseDown, which means it should have some context of the mouse position when it was clicked in order for it to have occurred. The WmMouseDown handler for NotifyIcon does have the ref Message m property which other controls use to establish the correct position, however it seems to disregard this property and not use it in the event handler. I'd call this a major bug.
Since its post-mortem, getting the Cursor.Position inside of MouseDown will not give you the exact last location in which the MouseDown was raised after the tray icon is clicked. There is a small delay between you clicking it, and it raising the event in which you can further move the mouse. You can test this out yourself with an application that gets the mouse coordinates by quickly moving the mouse after clicking the tray and getting its location within the MouseDown handler. A workaround (which answers my question) would be to save the last location on every MouseMove using Cursor.Position instead and using this last location on MouseDown as the location that clicked the icon. All of which spells out a clear need for the mouse location of when the event actually occurred.
Apparently, I am the only one who cares about these inconsistencies in .NET while a lot of people seem to tolerate them or not understand their implications properly.
Its not ideal because the framework is designed to not send proper mouse event arguments as Hans pointed out, but one workaround is to save the last location on every MouseMove using Cursor.Position and using this last location on MouseDown as the location that contextually clicked the icon.
Have you considered setting a global mouse hook? It would bypass the typical WPF event model, and you would have to manually determine coordinates. This may involve additional API calls.

According to this question, the answer begins with "The MouseEnter/Leave events are too unreliable to do this." What exactly makes these events unreliable?
The mouse position is only polled every so often. It's very possible that one of those events - the mouse entering, or leaving, could occur between when the polls occur, and the events would not fire correctly.
This also makes a pretty concrete assumption that mouse movement will be continuous, rather than discrete - what if the user has a touch screen monitor? What if the mouse goes directly from inside the control to being way outside it, with no movement in between?
You missed the point entirely. These events are unreliable for the OP question, not in general.
The question was about seeing if the cursor is inside the forms client area. Having many controls the MouseEnter/Leave are unreliable because you will get these events even if you are inside the form's area.
I want to how to implement this
Till i press the mouse button down i want some code to execute. The problem is I used mouse Down event but it works like a mouse click event.
Can you please help.
Create 2 functions, one to start your code to execute, and one to stop it.
Call the start on a mouseDown event, and call the stop on mouseUp.
Unless I don't understand what you're trying to do, that should be the way to go.
Here is the problem:
I have a simple c# form
I have a simple c# user control containing a picturebox and other button.
My form contains one instance of the user control.
I want that when the user do a mouseEnter in the picture box, the mouse cursor change and when the user do a mouseLeave of the picturebox, the mouse go back to normal.
What is happening now is that the events are not fired at all. I put break point into MouseOver, MouseEnter, MouseMove, MouseLeave, etc and none of thems fired. It's the first time I have this problem in C#.
I think it has something to do with the "routed event" but I can't figure it out. If there is another way to achieve what I'm doing, this will also be considered a solution. What is important is that at the end, the user control will be the master of the mouse cursor over his "territory".
Thanks in advance!
What events are you using? The UserController.MouseEnter and UserController.MouseLeave events or the PictureBox.MouseEnter and PictureBox.MouseLeave events?
You should use the latter as the PictureBox will handle the event if the mouse enters the user controller directly through the PictureBox.
As InBetween wrote, PictureBox.MouseXXX should be firing. You can trap those in your UserControl.
If you want the event to be fired on behalf of UserControl, just disable the PictureBox. Be aware though that the event would fire for any mouse position over the UserContrl, not only the PictureBox.
