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.

View 3 RepliesPrivate 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]....
View 1 RepliesHow 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 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
[CODE]...
How I could implement this?

I have a custom cursor that I have as a ico file as cur files are only mono coloured and 32x32.
The only problem in using a ico file is that I can't set where the hot spot is and at the moment it is set in the middle of the icon which is no help
I was looking on the msdn website and it said to set the hotspot like this
Dim instance As Cursor
Dim value As Point
value = instance.HotSpot But I don't know how to set the point value to (0,54) which is where I want the hotspot to be located.

I am attempting to get 7 NumericUpDowns to display the value of the application setting they are bound to. Each UpDown has its own setting binding. The setting is a decimal datatype with a value of either 4 or 6 as default. I need the UpDowns to display the setting value when the form loads. At the same time, I need any change made to the UpDowns to be saved to the same setting so that the application can both display and use the new value the next time it runs. Unfortunately, the only way I can get them to display anything other than "1" is to hardcode a constant value, and I don't want it to be constant. I think this is the last bug in my application and would love to get it figured out, but I've spent over 8 hours on it with no luck. Here is the applicable code.

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.
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?

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.

Here is the code:

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 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.
