Mouse.Click And Mouse.MouseDown - Delay The Mouse Down Event

Apr 15, 2012

I 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.

Drawing On Picturebox Vs Drawing On Form?

Feb 18, 2012

I need some code to draw a resizable, draggable rectangular cursor (or selection box) on a picturebox. I found some excellent code (albeit rather old) that does just that, but on a form rather than a picturebox. I have tried converting the code - basically moving things to the picturebox events (Paint, MouseDown, MouseMove etc). It nearly works but leaves a trail behind it when you move or resize the cursor. In other words, the selection rectangle is not being erased before being drawn in the new position.

Is there some fundamental difference between drawing graphics on a form and drawing on a picturebox that would cause this behaviour? Something like, when you invalidate a form and cause a redraw it erases what you did last? If not, then I just need to dig a bit further and work out how the cursor is being erased from the previous position.

Here's the original code that works fine on a form:

Private DragRect As New RectangleF(20, 20, 100, 80)
Private Adornments(7) As RectangleF
Private MouseInRect As Boolean = False

Click Button To Insert Drawing, Click Drawing To Get Option To Delete - VB Versus Access

Jun 21, 2010

Say I have 3 Buttons, labelled: Unit 1, Unit 2 and Unit 3. When I click on any button I want a drawing of that unit to appear on screen at a pre-specified starting point. Thereafter when I press any other one of the buttons the unit drawings appear alongside each other in a line. So I could end up with:

Find Out Wherer A Mouse Button Is Pressed When Mouse Pointer Is Leaving A UIElement?

Apr 6, 2011

I've been working on a GUI in WPF which I'm fairly new to, having only used Windows Forms up until now. So far, my GUI is very simple: it contains two rectangles, each of which drops a shadow. The shadow creates an effect of rectangles "floating above the canvas" so to speak.

When one of the rectangles is pressed, the myRectangle.MouseDown event is handled such that the shadow goes away, thus creating an effect of the rectangle being pressed down onto the canvas, like a button.Similarly, when mouse button is released, the myRectangle.MouseDown event is handled such that the shadow reappears and the rectangle "floats" again. This behavior make them resemble buttons. Note, there a reasons I want them to be rectangles and not custom buttons.

[Code]...

If the pointer leaves a rectangle while mouse button is pressed, I'd like shadow to reappear. This is arguable simple, because theoretically in this case, any time myRectangle.MouseLeave is raised, the shadow should come back on, even if it was already there.If the pointer left a rectangle when mouse button was pressed, then came back while before the button was released, I want the shadow to disappear again. This one is what gives me problems. No idea how to do this.

Interface And Graphics :: Mouse Control - Move The Mouse To A Given Pixel Position (x, Y) And Cause A Click

I wish to move the mouse to a given pixel position (x, y) and cause a click. I don't want this to be limited within a form, as I want to control another application. I'm using VB 2005.

Mouse Hover And Mouse Leave To Open And Close The Window Form

Nov 5, 2009

how to raise the mouse leave and mouse hover events for VB when i place my mouse cursor over the button.

When my mouse cursor is over the buttons, it will raise the mouse hover event and open the form, then when the mouse leaves the button, it will close the form upon raising the mouse leave event.

but currently, When i excute this two events, the for will open and close very,very fast. so fast that it is like spamming the VB.

So i am wondering how to change the code that i have to excecute the event one time every time the mouse is over the button which is created at run time.

the codes to execute these two events are:

Private Sub Button_MouseLeave(ByVal sender As System.Object, ByVal e As System.EventArgs)
For Each ctl As Control In PictureBox1.Controls

Mouse Hover And Mouse Leave To Open And Close The Window Form?

Nov 12, 2009

[URL] I have tried heslacher's method which is Hi clzanas, you problems had been the result of calling a for each loop inside the events. If you only want for the button you hoover / leave to call the ShowDetails.Open/close, then you can take the code below:

Private Sub Button_MouseLeave(ByVal sender As System.Object, ByVal e As System.EventArgs)
If TypeOf sender Is Button Then
ShowDetails.Close()

[code]....

But i got the same results as my previous code, resulting in the form opening and closing so fast that it is like spamming the window.

VS 2010 Any Tips Or Techniques For Debugging In Mouse Move Events / When Mouse Button Is Down / Has To Stay That Way?

Jun 6, 2011

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.

How do I change my code so that it will "freeze" the mouse once it finds the color? [Code]

C# - Mouse Event Fires When The Mouse Over Child Control?

Aug 24, 2011

I have set the controls mouse enter and mouse leave events. My problem is that the mouse leave event fires if I mouse over any of the child controls (like the name box for example).What I need is for the mouse leave event to fire when my mouse leaves the entire control, rather than firing when I mouse over any of the child controls. Here are the events as I have them so far:

Private Sub DeliveryControl_MouseEnter(sender As System.Object, e As System.EventArgs) Handles MyBase.MouseEnter
Me.removeImage.Visible = True
End Sub
