how to find the x,y coordinates of where my cursor is in an editing control like richtextbox. I don't need the mousepointer coordinates but the editor's cursor position.I found this VB code to achieve this. How can I convert it to vb.net ? Or is there a simpler solution ?
View 6 RepliesHow do i find the cursor coordinates on the screen in VB 2005 code?
"label1.Text = e.Location.X" Only gives you the coordinates in the program window itself, i want it to be displayed in a label/textbox in relation to the whole screen.
With VB2008 I am working with a picturebox that I am capturing the pointer position on a mouseup event. I am using the following to get the mouse location
Private Sub PictureBox1_Click(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseUp
Dim mp As Point = PictureBox1.PointToClient(MousePosition)
'...
End Sub
This appeared to work fine until I tested it on a Windows 7 system. The mouse position it captures is wrong (is offset from the actual click). If you make multiple clicks, they are positioned correctly relatively to each other, but they are skewed away from the point(s) you are actually clicking. It�s like they are off a fixed amount. It works 100% in Win XP. Could it have something to do with the Aero theme on Win 7? Would this happen to be a known issue or result from a common coding mistake?
how can i get the current position of the cursor in real time inside a picturebox?

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.

View 5 RepliesHow to get the line number where the cursor is in a RichTextBox? I'm using VB 2010
View 2 RepliesI 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.
View 6 Repliesis there a way of getting the screen coordinates of individual cells on an open Excel sheet, what I want to ultimately do is pass in a cell range say, "A5" into a function and watch the mouse cursor move slowly to that cell. I know this might seem a weird request. I already have a mouse move function but that accepts the x/y coords in pixel terms where excel using .TOP and .LEFT give an entirely different format?

View 2 RepliesI have a couple of TextBoxes on a Form and also a RichTextBox control which is associated with a ContextMenu1. Now, while my MouseCursor still blinks friendly in one of my TextBox controls, I right-click the RichTextBox and get surely my ContextMenu1. However, this ContextMenu won't do me any good unless I first left-click my RichTextBox in order to set my cursor in there and then right-click again to open the ContextMenu. I've tried to work with RichTextBox.Focus() and also with something like ... If
e.Button = Windows.Forms.MouseButtons.Right Then ...
But nothing seems to do the trick.

View 3 RepliesI'm writing an vb.net application so that the user can type text to be added to a website. I'm using a richtextbox and I've added the facility to hyperlink selected text. This all works, but when the mouse cursor moves over a hyperlink it changes to a hand; how do I stop it doing that? It's confusing for the user as it looks like clicking the link will do something and it makes it awkward to correct spelling within the text of the hyperlink.
View 3 RepliesI 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.

View 5 RepliesAnyone know how to make the text cursor (claret) wider in a RichTextBox control? It seems to ignore the setting in Vista settings and does its own thing instead. I wouldn't describe my vision as being seriously impaired - just middle aged!
On a high resolution screen it is a real chore trying to find the text cursor position. I've ended up doing a heavy kludge of putting a little image of an arrow on the screen attached to a timer control to track and point to the cursor position!!! This is a very silly work around. It must be possible to make the text cursor wider somehow? It is only one pixel wide and I can barely see it. I can't be the only one who struggles with these narrow cursors?
I am trying to build a coordinates system but am having trouble with how to.. What I have sofar is a textbox that allows the user to enter a length. This length is user defined but never smaller then 610 in length since this is the minimum unit size we use to build timber frames. The overall length of a timber frame is infinite (well not really, but it is for what I want) the timber frame has beams every 610mm set apart from each other (this is a legal requirement) so I want my vb.net to set coordinates for each beam at intervals of 610 then write that coordinates system to a text based *.SCR file

View 6 RepliesIt is very easy to move your cursor to a specific coordinate but my question here is how do you move your cursor to an image? Now what this would involve doing is importing an image so the program understands it, then finding that image on your screen (maybe through RGB colors). How exactly do you do this? What is the procedure?
Say I want to import this image: Now I want the program to find that image on the screen (THE START BUTTON) and then move my cursor on it.
so cursor.position = new point(the image)
