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.

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 am using a WPF richtextbox to create a syntax highlighter for code provided in a textbox. I want to have it automatically adjust the rich textbox as I am typing, using a thread timer I reset the contents of the rich textbox. I am trying to keep the cursor where it is suppose to be. I don't loose any text characters during the parse (except line breaks).
I don't know how to keep the caret position where the user has left it in the text. It defaults to the end of the document. I attempt to store the current caret position in the text and then set it to the document after I make my changes, however the error I receive is "Cannot set CaretPosition to be outside of RichTextBox." So I set the caret position to the bottom of the document.
WPF, VB.net, .net Framework 4.0
Here is the code.
Public Sub FormatText()
If IsNothing(rtfContent.Document) Then
Exit Sub
End If
Me.rtfContent.IsEnabled = False

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.

I have created a maskedtextbox to do a simmple validation >L99999. My problem is when the user clicks on the empty box the cursor stays where they clicked it, not at the beginning of the box as it would with a normal textbox. I have found some suggestions but these all seem to affect the way the cursor moves within the box rather than just changing the start position. As far as the end user is concerned the box should behave just as any other textbox but with validation.

I am working in VB 2008 and I have a textbox on a form that is used to enter a parcel number. I can enter the number in a 15 character string such as 12345678...... and it works just fine. The parcel number in real life contains dashes to make it easier to read, decipher, etc. so it looks like 12-3-45-67....... Under the textchanged subroutine for the textbox I have a case statement set up that checks the length of the parcel number as it is entered and inserts the dash accordingly.

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. 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 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.

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?

Would someone advise as to why the cursor position code does not work in the downloaded code snippet this code is from the second tutorial located within VB 2010. The debugger moves through the method but the cursor is not affected in any manner i.e does not move to position 10,10 when called to do so.I am using XP windows 2003 as a virtual machine through Macintosh OS X 10.5.8 -maybe this has an effect somehow?

I have the following code to set the cursor position in a 16bit display:
linCursor.x1 = VB6.PixelsToTwipsX(lblDisplay(pintCursorPos).Left) + 10
linCursor.x1 = VB6.PixelsToTwipsX(lblDisplay(pintCursorPos).Left) + 10
linCursor.X2 = VB6.PixelsToTwipsX(lblDisplay(pintCursorPos).Left) + VB6.PixelsToTwipsX(lblDisplay(pintCursorPos).Width) - 10
I need this code to be converted to vb.net.

I know how to get the cursor position but how do I add a character to that position. Like I want to have a button that adds a specific character at the position of the cursor.
I don't see any richtextbox properties that allow me to add anything at the cursor position.
If TypeOf Me.ActiveControl Is RichTextBox Then
Me.ActiveControl.SelectedText = Chr(176)
End If
