Monitor The Current Position Of The Mouse Cursor?

Apr 21, 2009

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 _


But Appdomain.GetCurrentThreadID generates the warning: "'Public Shared Function GetCurrentThreadId() As Integer' is obsolete: 'AppDomain.GetCurrentThreadId has been deprecated because it does not provide a stable Id when managed threads are running on fibers (aka lightweight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"?

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


How I could implement this?

Set The Cursor Position In A RichTextBox?

Dec 12, 2011

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.

At the moment, I'm using:

Me.tbLowerBody.SelectionStart = 0
Me.tbLowerBody.SelectionLength = 0

However, this seems to provoke my "Would you like to save changes" dialog on closing the RTB even though no actual changes have been made.

VS 2010 - How To Set New Cursor Position

Jul 21, 2010

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.

Forms :: Get Name Of Control At Cursor Position?

Sep 10, 2009

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?

TextBox Or RichTextBox Cursor Position?

Nov 26, 2010

I Would like to position the cursor in a text box using X,Y coordinates with X being the line number and Y being the column number. Is there any way to determine the line and column numbers of a textbox that is full of text. Using the .selectionstart paramenter only lets you position the cursor a certain distance from the beginning of text but there is no line information that I know of. By the way, I not an expert at VB so bear with me if these questions seem kind of basic.

How To Change Cursor Position To PictureBox Location

Jun 30, 2011

I created a game where you use the mouse to play, it's like the game labirynth. You can't touch the walls or you lose. When I start the level I want the cursor to appear in it's starting position, which is a red picturebox.

Here is the code I used:
Windows.Forms.Cursor.Position = New Point(679, 650)
The location where the cursor appears is actually dependent of the resolution of the screen.

For example: with my monitor resolution, the location (679, 650) is right on top of the picturebox i need it to appear on. but if you have a different resolution on your monitor it will appear on a different place. I need to actually make it appear on top of the picturebox.
