XYpoint.X = MousePosition.X[code].....
I have a form with a picturebox called Chartbox and I'm trying to fire a mousehover event when the mouse is over a drawn region (Cregion). My code (see above) is not working.
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..

Public Class Form1
Private Sub Panel1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Panel1.MouseDown
Debug.Print("MouseDown")

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 am using vb.net and i want to fire/execute labels mousehover and other events when user pressed mouse left buttion.For Ex.: i want to execute mousehover event when user pressed left mouse buttion. Without pressing left buttion you can execute but i want to execute with press.
View 4 RepliesI have a SplitContainer control with DataGridView and WebBrowser controls. I'm trying to call focus to the WebBrowser whenever I hover over it so I can use mouse wheel to scroll. I can do that with the DataGridView since it supports MouseHover, but what can I do with the WebBrowser control to achieve the same thing?
View 10 RepliesI've got a textbox with a mousehover event and that event will only happen once and then I have to move my mouse out of the text box before it'll happen again. Is there a way to reset the mousehover event 'trigger' so that it happens as many times as I want?
View 7 RepliesI'm creating a type of drawing program. The user can draw a line, much like in word or paint, etc. But once the line is drawn (to a picturebox or bitmap in memory), I want the user to be able to click on the line and drag it around (translate it).
If I know the coordinates of the endpoints of the line, as well as the pen width it was drawn with, how can I tell if a certain coordinate (mouse location) is contained by the line?
My first thought was to take a mathematical approach, like get an equation for a line, and check to see if the coordinate belonged to it. But for a higher pen width, the line is thicker, and thus contains more points.
How can I tell what coordinates are part of the line? Is there some sort of intersect function in the gdi that takes a line?
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?
View 3 RepliesI have two custom action listers. One that handles Mouse.Click and one that handles Mouse.MouseDown. My question to you is, can I delay the mouse down event so that it does not intefere with the code of the Mouse.Click event? I have tried adding a timer and waiting x amount then setting a bool value to true, but the code executes to fast and it skips the other code.

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.

Currently I have not found a way to generate an event when a user clicks on a line that is drawn in my workspace area. The line that is drawn is created by calling the function e.Graphics.Drawline(Connector,X1,Y1,X2,Y2), where Connector is a System.Drawing.Pen object and X1,Y1,X2,Y2 are integer coordinates of the two points to draw the line between. I have not found any events such as Click that are associated with the line that I can use. Do I need to create a custom event for these lines if so how do I go about this?

I am trying to drag and drop items from a listbox into a richtextbox? I can not get the .DragDrop event to fire? I have copied and past the code from [URL]
I can get the .DragEnter event to fire. The mousedown event fires the drag and drop, is there something for mouseup?
I have two questions in my mind!
1) What's the difference in mouse hover and mouse enter event in regard of vb.net?
2) Is embedding a resource in application more efficient or linking it on compile time?

I can't seem to get the Form.GotFocus event to fire.I have two forms - a main window and a debug window.The debug window will always be shown with the main window. But, I don't want the debug window to appear in the task bar - it's unnecessary.While my program is running, when I select another program, my main window and the debug window are placed behind the program that I selected. From the task bar, I can bring my program back to the front by clicking on it in the task bar. The problem is, that now my debug window is behind the other program.I have code that will "DebugWindow.BringToFront", and it works. But I need some way to run do this when the main form gets the focus.I do not wish to make any of my forms Modal. At least not permanently. If the solution is to change the modal property of the form temporarily, then that wouldn't be a problem.
I tried Me.Enter, Me.Activated, Me.Click and a few other events. Me.Click only works when I click within the Form window, not the form's title bar. Me.Activated caused problems - The code ran, but it would always end with the focus on the Debug window. When I tried to click on the main form, the Activated event would fire again, sending the focus back to the debug window.[code]
