NotifyIcon - BaloonTipClicked And Mouse Events
Aug 19, 2010
I've got a NotifyIcon that signals downloadable application updates. I want the download page to open on a Left Click on the NotifyIcon and on a Left Click on the NotifyIcon balloon (on screen for 10 seconds). However, when I handle the BalloonTipClicked event I can't figure out if it was a Left or a Right click. Thus, while the balloon is still on screen and the user Right clicks on the icon, I get both the popup menu and the download page opening. How do I detect the Right mouse button was used?

I am writing program in VB 2003 .Net and Framework .Net 1.1 I'm using NotifyIcon class without form.
Private WithEvents _niTray As System.Windows.Forms.NotifyIcon
Private Sub _niTray_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles _niTray.Click
Console.WriteLine("{0} {1}", sender.ToString, e.ToString)
End Sub
How i can detect which mouse buttons (left or right) cliks?

I have a program which puts an icon in the notification area and has a menu associated with it available by right clicking on the icon. I want the menu items to be selected by single left clicks but I also want the user to be able to single left click on the icon itself to do some other functionality.
Here's the problem - the single click on the menu first fires the notifyicon1_click() routine and then the menuitem1_click() routine. How do I know in the notifyicon1_click() whether it has been called from a menu click or a click on the icon itself?
the following piece of test code duplicates the problem
Imports System
Imports System.Drawing
Imports System.Windows.Forms

I have a NotifyIcon (named TrayIcon). When I right-click it I get a menu. When I left-click it I want the form to be shown when it's minimized or hidden. But I can't find a way to get the latter done.
Private Sub TrayIcon_MouseClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles TrayIcon.MouseClick
If e.Equals(MouseButtons.Left) Then
Me.Show()
End If
End Sub
When I debug, "e" shows "almost" same value ({X = 0 Y = 0 Button = Left{1048576}}) as"MouseButtons.Left" (Left{104875}) in the quick-watch window, still the Me.show is passed. I think this has to do with the X and Y, and "MouseButtos.Left" is of the type "System.Windows.Forms.MouseButtons" and "e" is of the type "System.EventArgs", but I have no idea how to get the right comparison.It's partially working though. When I leave out the if statement and only the Me.Show() is left, both right and left-click make the form pop-up. With the if statement, it never shows up.

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 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 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.

I have a form with 2 contols that I with to connect by drawing a "wire" on the screen. It goes like this: you mouse down on the first control then move the mouse while holding the mouse button down. When the mouse is over the 2nd control the mouse button is released and the controls are wired.
So I am playing with mouseup, down, move, etc. When the mouse is over the first control I get mouse moves from that control, but when it moves off the events stop, and I get no events from the form even though the mouse is there.
Is there a way to do this? I have seen it done in a Java app. I could brute force it and just draw a box on the form instead of a control, but that sounds like a step back.

Normally the event: PanelTransparentMarquee_MouseUp is only raised when the mouse is within the PanelTransparentMarquee panel. I'd like it raised where ever the mouse is on the screen.So in the load event for the usercontraol containing
PanelTransparentMarquee panel I inserted
PanelTransparentMarquee.Capture =
True
But I still only get the PanelTransparentMarquee_MouseUp event when the mouse is within the PanelTransparentMarquee panel.

I am writing a program to draw lines over an existing image within a PictureBox. The routine works perfectly INSIDE the PictureBox (I'm drawing a rubberband line), but I cannot get the mouse to work on any buttons OUTSIDE the picturebox. (In this example, Button1 doesn't respond)

I'm working on a grid of cells that is something like a DataGridView, but not really. The two are close enough that you can picture a DGV for the purpose of this question. What is actually there (and this is true for actual DGVs) is a set of cells drawn on the screen with a couple scrollbars for vertical and horizontal scrolling which are only drawn if there is too much data to show in the visible cells. There aren't more cells than the ones that are visible, so when you scroll the scroll bar, it looks like new cells are being displayed, but what is actually happening is that the existing cells are just being filled with different data depending on the position of the scrollbar. The key observation is that the set of controls displayed in the grid is always the same (unless the grid is re-sized, but that's not relevant to this issue). The appearance of those controls can change, but the controls themselves do not.
One of the features I am adding is the ability to drag-copy data similar to how Excel works. In my case, if you click on a cell, then drag outward (move the mouse while holding the button down), all the cells in the selection rectangle are tinted green. This works nicely. Some of the cells are enabled, while others are disabled. If the drag selection includes disabled cells, those are not tinted. Only enabled cells can be selected, though a drag can cover disabled cells. The relevant point here is that some cells are enabled and some are disabled.
The feature that I am adding is the ability to do drag selection beyond the visible edge of the grid. The grid is a monthly calendar, and I simply can't get 31 cells onto even a wide-format screen. What I am trying to do is allow the user to do drag-copy onto days that are not currently visible. The way I do this, the user clicks in a cell, then drags out to the border, at which point the grid scrolls (the scrollbars move, and the contents of the cells is updated as a result of the changes to the scrollbar value). This is largely working.
The way I handle the selection is that when the user presses the mouse button while over a cell, a flag is set to indicate that the button was pressed, and the current cell is recorded (so that I know where I started from). MouseMove events are used to figure out what new cells the user has visited, and set the selection area based on whatever is under the rectangle described by the initial click point and the current point. Lastly, when the user releases the mouse button, the MouseUp event initiates the actual copy. At that event, I know that the user is done with that copy action. Therefore, the MouseUp event is kind of critical, and therein lies the problem.
As I mentioned, some of the cells are disabled and some are enabled. Disabled controls don't raise events. If I click on a cell, it HAS to be enabled, but that's fine. The problem is that if I then move the mouse in such a fashion that the grid scrolls such that the cell that I had initially clicked on is no longer enabled, then the cell doesn't raise events any more, and the MouseMove and MouseUp events stop happening.I only see one viable solution, which is to not toggle the enabled state of the grid cells. Instead, I would have to have to add a custom property that would make the control act and look disabled as far as the user was concerned, but it wouldn't be disabled as far as the program was concerned such that it would keep raising mouse events. This would be pretty rough, since I would need to prevent the control from appearing to have focus even though it technically would have focus

I'm trying to make a way to navigate around a custom grid. Basically, I'm implementing the drag-copy feature from Excel. Right now, you click on a cell grid and can drag around the grid. Anything in the drag area gets a green tint. Once you release the mouse button, whatever was in the first cell selected is copied to all the others that are tinted. That works pretty nicely, but it works only for the cells visible on the screen. I can live with that, but decided that if you dragged over the scroll bars or the column or row headers,then the grid should scroll (if there is anywhere to scroll).
That's where the problem arose. It turns out that scrollbars don't raise the MouseMove event (at least not as far as I can see), and the MouseEnter and MouseHover events are not fired as long as the mouse button is held. Interestingly, the MouseLeave event does occur when the mouse button is held, just as the MouseMove event is occuring for all the cells. That's pretty annoying. Why do some mouse events get raised when the mouse button is down while the others don't? Also, I suppose, is there any way around this?

First, I want to know if the mouse is in some area. Then, I want to check if the mouse holds the left click. I want to check as long as the left button is down, and I want to track the mouse's position. And finally, check when the left button is released.
So, in short, where should I start for tracking mouse events in my form?

I'm trying to create a user control that will provide a draggable splitter between two panels — exactly like SplitContainer — in a custom IDesignerHost implementation. SplitContainer itself, as far as I can tell, is not an option; it will raise an exception unless used in Visual Studio's Designer.
My implementation would look roughly like this, except that I'm not receiving the necessary mouse events. I've tried event handlers, On* overrides and overriding WndProc in the user control itself, the host control, and the parent form, but I don't appear to receive WM_MOUSEMOVE, WM_LBUTTONDOWN or WM_LBUTTONUP events anywhere. Per this bug report, I should be receiving WM_MOUSEMOVE in "the control designer"; I'm not sure what that refers to in this case.
how I can implement a draggable splitter?

I have a program that I would like to create application-level MouseEnter and MouseLeave events for. Basically I have an app that I'd like to leave open that would be very opaque when not in use, and when the user moves the mouse anywhere within the bounds of the application, it becomes solid, and when they move their mouse away from the application, it becomes opaque again.
The obvious problem is that MouseEnter and MouseLeave are control-specific and so they fire every time you move over a button or menu or whatever, so Leave and Enter are constantly firing even though you haven't "left" or "entered" the application.
So, is there any way to create mouse events that only fire at the application level?

I have some code in a label's mousemove event that allows it to be dragged around my form while the left button is held down. While this is happening none of the other controls on the form respond to their own mousemove events as the mouse pointer passes over them. Is it possible to make more than one control respond to mousemove events at the same time?

I try to catch the keydown event, but arrow keys don't fire this event, although I set KeyPreview = True. Arrow keys neither fire the KeyUp event. Not on the form or on any controls..
What is required to handle:
1. Arrow keydown or keyUp event with individual event handler based on mouse focus/hover (does the control have focus if mouse hovers on it, or it needs to be clicked?)
2. Mouse scroll events individually based on "mouse focus"
I don't actually need for the form... Since all the form is covered by controls.. But I need individually for different controls. Which are just buttons, labels and a chart control.

I need to draw lines each time a mouse moves over teh form....
currently i use the Mouse_Move( ) event, this caputures my mouse moves. and it creats lines. But i need to draw those lines on to the form.
This lines are not drawn when form_laod() fires that will trigger OnPaint(). Te lines must be drawn to the form when the mouse moves over the form.
How do i do this? I currently know how to capture the points evenry time mouse moves but i dont know how to draw the lines each time mouse moves. this is because im in dount of the event that i have to use.

is it possible to link a personal created class with a Mouse Event? I created a class and I want to make it possible to make it interactive with the mouse. So when the user goes over the GDI-created shape (which is declared and created in that class), he has to see some information about that shape, like the name etc.... And the user has to be able to drag and drop that shape.

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.
