I am trying to implemented a custom dragging operation to sort panels.
I assign an object to a variable in the MouseDown event and track it's relative position by examining the MouseMove event of the neighbouring panels as I drag the mouse over them.[code]...
I wish to send a string held in a var to an IP address and Port number both also held in vars. I also wish to listen to a signals coming in on a particular port number so when particular strings are received I can trigger other transmissions.

View 3 RepliesI have already created the provision to allow the user to create and delete the button control at runtime. But now i am stuck at the dragging part. I am planning to let the user to drag the button using the mouse click event and the keyboard (left,right,up and down) key event.
May i know if there is any codes that allow the user to drag the button control around?
the below is my code for the creation and deletion of button controls at runtime.

I am writing a small program for work in VB.NET which I have not used a large amount of. I have come across a small problem that I cannot seam to find a solution for. I have created an array of buttons 113 deep and created a click even for every button. now the problem that I am having is that each button relates to a structure in another array and when a button is clicked I need to be able to lift the information out of the relating structure and load it into a few text files. What I cannot work out how to do is how to work out which button is clicked.the array is set out like below:
Sub SetButtonArray()
buttonarray(0) = btnPark0
buttonarray(1) = btnPark1
buttonarray(2) = btnPark2
[code]....
and finally the event itself which is where I need to be able to work out which button in the array sent it.
Private Sub ButtonArray_click(sender, e)
Dim park As Integer = sender.
LicencePLate.Text = sender.text

(me = an absolute beginner in WPF / VB2010) how to get the type of sender in (ByVal sender As Object)? Purpose: when two different Objects call the same subroutine, find out which one actually called it.

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.
I am new to VB.NET, Now i'm working with Events in VB.NET, I have two event methods, Mouse Click and Mouse Down for a single button in a form, I have displyed a message in each of these methods but only mouse down event is triggered. Why Mouse Click is not triggered? Similiarly I Did the same for Mouse Enter and Mouse Move for a particular button, in this case both the events are triggered.

View 1 RepliesI'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.

Lots of ovalshapes... What I want to do is that when the mouse is over one of the shapes, it will display the name of the shape in a label. I can easily do it for each shape like this:
Private Sub p34_mouseover() Handles p34.MouseMove
Label1.Text = p34.Name
End Sub
[Code]....
But if I do it that way, I need to make like 120 subs. Is it possible to make one sub/function/whatever that handles this for every ovalshape?
I am rotating a picture dependant on the mousemove.
Private Sub PictureBox1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseMove
[code]...
To simplify the part I am having problems with: rotationX = CurrentPositionX + ((InitialPositionX - MousePositonX) / SlowDownDivisor)
As an example, this occurs in both X and Y; If I click and drag in the X + Direction and release the mouse button it does exactly what I want, rotation in the positive direction. If I click and drag in the X + Direction and then drag in the X - direction, the rotation continues to be positive, it doesn't reverse. If I release the button and then click again and move in the X - direction the rotation is negative as it should, but it will continue to rotate in the negitive direction until the button is release.
Alright my goal is to test to see if the user has dragged a label over a button. I have add event handlers for MouseMove and ButtonEnter, the trick is that i dont want the buttonEnter sub to fire unless the user is actually dragging a label.Dim dragging As Boolean = False
[Code]...
I thought would work but because the user is dragging the label the mouse never actually enters the button field. I also tried doing lbl.location = button.location... but unless the label and the buttons are the exactly the same size in exactly the same location then the event wont trigger.
I did a research but I can't find what I wanted. How I can detect the mouse that if I have move it or not?
I hope this is the last things I needs for the day.
I have a picture box that i can click on and drag the mouse around to define a region with in it. The problem is the region is not reset when you click and drag, only when you simply click. You then need to click and drag again and it does not set the region to the new location of the mouse. It is hard to explain so i have example code below. Simply copy and paste into a form named Form1 of a new project and run.

Actually I'm creating a simple paint application in VB.Net 2010. I want to draw shapes in my application same as we do in Microsoft Paint using mouse.
I'm a bit successful also using mousedown and mouseup events of a picture box. The mousedown event sets the starting point and mouseup event sets the ending point(diagonally opposite point of rectangle.) The problem is "Nothing seems to be occuring between mousedown and mouseup events(Well..that is obvious because I didn't add any code on mousemove event). My question is: "Can I do something to see a growing rectangle during mousemove event?". The rest of the drawing should remain unaffected.
How do I execute "Button1_Click" when click "Button2" like "Button1.Click(######)"? When I try to write Button1.Click() then that keep asking me "sender As System.Object,e As System.EventArgs". What value that I have to have "sender As System.Object, e As System.EventArgs"

I am creating an application and am very new to VB. I have 4 buttons on my form which is like my applications main menu. I would like that each of the buttons behaves in the following way when there is a mouse rollover: The Button back color is changed from the default to Red The Button text is changed to Blue, Bold, and increases in font size I would also like all the buttons to go back to their initial state when the mouse leaves.
Another thing, instead of me writing code for each of the buttons event handlers (Mouse Hovers, and Mouse Leaves) is there a way I can write this code once, maybe as a function and then always call it for any button that I create from here on so that any new buttons take on this behaviour.
When I write public events for my business objects, I've adapted the habit of always passing the instance as "sender as Object", in addition to additional specific parameters. I just asked myself now why am I not specifying the class?
So for you with more experience; Do you ever pass the distinct class as sender in an event? And if so, what are your decision criteria for when this is ok/not ok?
Well i've been trying to make something run with a lot less code(and faster) but it seems with SendKeys some things are getting lost(or discarded) by the program, its only the arrow keys as I try & make it complete a pre-defined maze to see how fast it can be completed.
If I use SendKeys("RIGHT 8") for example the maze usually only moves a few times, sometimes maybe only 1.
Also I looked up how to hold a key down/simulate it but it's not working for the arrow keys(untested on other keys).
The only way i've made it work is delays, decently delayed like 200ms & it's a huge maze but if i hold a key manually I can go much faster yet sendkeys method can't go that fast using individual presses this is why I want to simulate a holding down action.
---it must be working xample code I can make it work for my purpose if it works like on button click, etc....but I tried copying full (supposedly working) codes before & they never worked for me/my key, xample cause i've looked & tried hard(with only failing results).
MORE INFO:Also I tried SendKeys.SendWait() which is meant to wait for keystrokes to be processed & that didn't help either so my best guess is the keystrokes are processed but discarded(like a movement delay code that doesn't queue movements but rather ignores extra movements)
i need some help with this problem. i have seen some solutions but written in C and im not that good to convert from C to vb.net.Well i want to 'do something' when i mouse move at an item of the combobox dropdown list.like when i move the mouse over "jkl" make the button1.text = "jkl"when i move the mouse over "def" item make the button1.text = "def"
