Cursor - Get The Position Of The Mouse Relative To The Browser Control
May 13, 2010
I have a hobby of making webbrowsers. I'm writing a new one, but it has an old webbrowser control in it (CEXWB). This means that I am using IHTMLDocument(s) rather than normal HTMLDocuments. I'm in the process of implementing a ContextMenu, but I need to get the position of the mouse relative to the browser control, so using something like Cursor.Position won't work. The Webbrowser_MouseMove event also won't work. I'm not sure why. I also can't use WithEvents with a HtmlDocument (like in my webbrowser ContextMenu tutorial) as I cannot Convert A System.Windows.Forms.HtmlElement into an mshtml.IHTMLDocument2.
So far, I have this code:
'The event which fires when the ContextMenu for the browser Opens
Private Sub cmenuWB_PopupOpen(ByVal sender As Object, ByVal e As DevComponents.DotNetBar.PopupOpenEventArgs) Handles cmenuWB.PopupOpen
I am working on a screen cropping program. The program works by expanding the current for to maximum and the opacity level set to 35% so the screencan be seen from behind. The cropping code is below:
Private Sub disect_mouseDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseDown Me.Opacity = 0
I've used the search function but couldn't yield any solutions. Sorry if I didn't look hard enough. Anyway, it's just a quick question. How can I find the mouse cursor X and Y co-ordinates relative to the form itself and NOT the screen?
I'm trying to create a hook to monitor the current position of the mouse cursor. Nothing important, I just need to count some pixels during interface design and wanted to learn how to create a hook, so I decided to go for a hard way instead of a sane way.
I've found example code which declares the following function:
<DllImport("User32.dll", CharSet:=CharSet.Auto, _ CallingConvention:=CallingConvention.StdCall)> _ Public Overloads Shared Function SetWindowsHookEx _
[Code].....
But Appdomain.GetCurrentThreadID generates the warning: "'Public Shared Function GetCurrentThreadId() As Integer' is obsolete: 'AppDomain.GetCurrentThreadId has been deprecated because it does not provide a stable Id when managed threads are running on fibers (aka lightweight threads). To get a stable identifier for a managed thread, use the ManagedThreadId property on Thread."
I've tried using ManagedThreadID, but that doesn't work. The thread ID returned seems to be the logical thread ID of the thread, as it runs in the .net runtime, rather than the Win32 thread identifier.
Calling the function ith AppDomain.GetCurrentThreadID works, but I really would like to have a "stable identifier" for my thread.
Can someone explain to me whether it is possible to use ManagedThreadID in this context (I assume not) and, if not, the things I need to avoid in order to stop the AppDomain.CurrentThreadID from becoming "unstable"?
I need to be able to take some co-ordinates from textbox and set them to the mouses position. I have tried a few things such as trying the 'new POINT' but i get the following error RDU.Form1.POINT has no constructors'What i am doing is sending the co-ordinates to a listener which then goes into a textbox and i want mouse to go to them co-ordintes.
Apologies as this has probably been answered a million different times a million different ways already. I'm trying to control the mouse. 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.
Private Sub pSalar_MouseDown(ByVal sender As Object, ByVal e As MouseEventArgs) Handles pSalar.MouseDown My problem is that this panel is the parent of labels, and when I click somewhere on the panel, I can't get it to trigger the event. If I remove the line below, it works ok (but then obviously it's not holding any children labels anymore)[code]....
How do I get the name of the (topmost?) control at the cursor position? The background: I implemented drag'n'drop from a dgv to a label and need to identify the control where the mouse button is released. I have enabled dropping on the label where the drop is going to take place. However, this label is the parent of say a hundred labels that are created dynamically in codebehind (I use this way to create a "dataview"). Therefore, I need to know which of these "child" labels the user drops the data onto.
I can get the mouseposition without problems (Me.PointToClient(Cursor.Position).ToString), but as I said, I can't get the name/text/ID of the control the user dropped the data on. Also, I ned to get the child control's name/ID/Text, not the parent label of course.In addition, it seems as if I can't select the row I click on in the dgv anymore, after I implemented the DoDragDrop on the CellMouseDown event. Any ideas? Should I use another event?
I have created a user control tha inherits from the NumericUpDown Control.Is it possible to set the cursor position within the control?I am validating the text OnKeyUp, and formatting it when it meets certain criteria.To do this i have to do me.text = Fomatted(Me.Text), which sets the cursor back to the position 0, i want to set it to the end of the text area.
I have a label (mylabel1) control that is say size 200 by 200. I then add another label (mylabel2) to it as:
myform1.controls.add(mylabel2)
When the mouse enters mylabel1, I want to say change the backcolor as:
Private Sub mylabel1_MouseEnter(ByVal sender As Object, ByVal e As System.EventArgs) Handles mylabel1.MouseEnter mylabel1.backcolor = color.red
[Code].....
this works fine except that when the mouse passes over mylabel2 which was added to the controls collection, it fires the mouseleave event for mylabel1. Is there a way to do this without having the mouseleave event of mylabel1 having to be checked against the mouseenter event of mylabel2??
I am ultimately going to have a parent container that has multiple children but I don't want the children to effect my changing colors and effects when the mouse has entered the parent.
I would like to accept input bytes or words from the serial port(this part can do using serial port control) and use those values to control position of the mouse on screen to use MSPaint. How can I control the mouse ?
I would like my 'quit' button to appear in the bottom right hand corner of my menu screen, but it seems that every computer in the office has a different sized screen, different size ration (some are widescreen) and different resolution. When I deploy my program, the quit button may appear off-screen (the user has to scroll down to find it) or it may appear half way across the screen on a widescreen laptop for example. If I set my form to 'maximized', is there a way to position a button relative to the bottom right hand corner of the form? Also, on one maximized form I have two datagridview's side by side. Is there are way to automatically set each one to take up half of the available form width, so they fill the form nicely?
I'm writing a VB.Net WinForms application that has multiple data girds on any given form. On one such form, the data grids are loaded into split containers which in turn are located on a tab control. The load method for each data grid is threaded so that an animated "Loading" form can be shown. I would like to position the new loading form (which is smaller than the grid) on top of, and preferably in the center of, the grid that is loading. Whats the easiest way to find the grids location within the main form so that I can adjust the loading forms location?
I've got a set of controls in a line inside"FollowTableLayoutPanel1", contained within "TableLayoutPanel2".I have them resizing according to the position of the mouse cursor; the closer the mouse cursor is to the vertical centre of the control, the larger the control is. Because FollowTableLayoutPanel1 has its anchor property set to "Top", it recentres itself in TableLayoutPanel2.It is possible for the recentring of FollowTableLayoutPanel1 to move a control one pixel further away from the mouse pointer, which causes the control to shrink, which causes FollowTableLayoutPanel1 to recentre, placing the control closer to the mouse pointer, which causes the control to grow,which causes FollowTableLayoutPanel1 to recentre, which moves the control further away from the mouse cursor, etc., etc., etc.The end result is that the whole setup judders and wobbles, constantly resizing.Full example code is provided below,and can be pasted directly into Form1 of a new project. Positioning the mouse cursor to correctly show the problem is left as an exercise for the reader :
Public Class Form1 Private Sub myInitializeComponent() Me.components = New System.ComponentModel.Container Me.TableLayoutPanel2 = New System.Windows.Forms.TableLayoutPanel[code].....
I'm trying to get the cursor position within a webbrowser control, and then create a text range starting from the cursor to a specified word or character.I have some code but instead of selecting the specified range it selects the whole html block.
In my application which is written on vb.net,i search for a word by typing the same in textbox here i have doubt to focus the cursor in the text box.. if i press first letter, say 'a', in textbox that will automatically search what are the words start with 'a'but after searching, cursor is not focussed in the textbox and to type another letter, say 'b', i need to bring my mouse pointer over the textbox and click so that i can type another letter.how can i keep my cursor focussed in the textbox unless i click somewhere else.
I My Problems is when i don't put number and the textbox is empty TextBox string value but the cursor is integer i tryed whith if not string.isnullorempty but have an invalidcastexception in SetCursorPos(MousePositionX, MousePositionY) and if i put all as string happens the same whit the infinite value (empty textbox)
Public Class Form1 Private Declare Sub SetCursorPos Lib "User32" (ByVal X As Integer, ByVal Y As Integer) Private Const MOUSEEVENTF_LEFTDOWN = &H2
Trying to set the cursor position in a RichTextBox. The contents of a document are opened into the RichTextBox and I would like the cursor to move to the very start of the text.
I'm making some snippets and I want to position the cursor. I've come acros "$end$" but all examples I see are in c#. Since recently I've started programming in vb.net again and it seems $end$ isn't recognized or doesn't work here. Is there another keyword in vb to do the same?
the program is that user add numbers in textbox through number buttons (its a calculatornow i have to add 2 more buttons. one <- and other -> and when press one of them the cursor moves in the text box left and right.i tried few things but none works. i have tired to insert "|" first and then try to move it but it either keep on adding or deleting the text.here is what i have tried so far . its not the whole code as i keep on adding and removing.
Dim str As String Dim loc As Integer If txtInput.Text.Length > 0 Then
I'm trying to set a new cursor position but I get this error: A call to PInvoke function 'mon! WindowsApplication1.Form1::SetCursorPos' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.
Here is the code: Declare Function SetCursorPos Lib "user32" _ (ByVal x As Long, ByVal y As Long) As Long SetCursorPos(457, 603) It used to work when I used VS 08 but now I use VS 10 and this problem has started to appear.
I have a user control, and want to be able to update its cursor while it is disabled. For example, say that I have a user control whose cursor is Default. The below code works ONLY when the user control is already enabled; if it is disabled the below code doesn't work and the cursor remains Default: Me.MY_USER_CONTROL.Cursor = System.Windows.Forms.Cursors.WaitCursor
This is maybe an weird question because I don't know if its possible so prepare .I am working on a project its a kinda autoclicker.It moves the cursor to positions and perform mouseclicks it all works perfectly.So when it runs you can't do something else on the pc because the cursor gets moved every 1-5 seconds.So I wanna now if its possible to kinda attach it to the program I am making it for so it moves the cursor and do clicks within the form of the program.
I am trying to use a windows form as a custom contextmenu which is fine as I have done a form with translucent background colour. However the problem is that I am having problems displaying the form at my cursor position. I have a mdi chaild form in my app and when I right click I want to display my custom contextmenu form at the point where I right click in the mdichild form. The only other thing is that I want the middle of the form to be displayed at the cursor point.
I'm having a difficult time getting cursor's position within the window I tried using : Cursor.Position.X and Cursor.Position.Y but it returns the position of the cursor on the screen and not in the window...
