When I right click in a richtextbox, a context menu appears with an option 'get line'. When that is pressed, it should return the line number in which the mouse cursor is in.
I was thinking something like:
Private Sub GetLineToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles GetLineToolStripMenuItem.Click
Dim intLine As Integer
[Code]....
How to get the line number where the cursor is in a RichTextBox? I'm using VB 2010
View 2 RepliesApologies 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.

I have a class library with a component class in it. Everything is in VB.NET. It's only one file so you can see it here [URL] . On line 92, there is the OnTextChanged Sub. I was thinking about adding ProcessAllLines() (as on line 128) to the end of that Sub, and it worked. However when I was typing in code to the RichTextBox (source which I used is here [URL] after each text change it was checking and processing ALL the lines. So I deleted ProcessAllLines() in the OnTextChanged Sub.I'm thinking about running ProcessAllLines() when the user pastes something to the SyntaksRichTextBox. However I do not know how to do that. I know that it should be something like:
If [CTRL Pressed] And [V Pressed] Then
ProcessAllLines()
End If
I also want it to be in the class library, not the application (Syntaks Demo).

That is what my program looks like so far. This is the code:

i have a trouble with clearing a particular line in a multiline text box have data inside
View 4 RepliesI'm using a couple of multi-line textboxes to check output from my program, but it always scrolls back to the top of the box. Is there some way to set it so that it's always scrolled down to the end? Scrolling manually doesn't help because it just keeps resetting to the top.
View 6 RepliesI have a RTB which I import with a set of 7 or 9 didit numbers, 7 for Staff and 9 for Students. e.g. Staff numbers [code]and depending on what is selected in a list box ('Student' or 'Staff') will generate a string to create user accounts. To further error check I would like to check if a line in the RTB = 7 And Listbox = "Student" Then msgbox("Data mismatch between User ID and Account type")
View 4 RepliesI would like to include the line numbers on the left side of a multiline textbox, much like what Notepad++ has. It should scroll along with the rest. Is this possible?
View 12 RepliesMy program plays sort of like a novel, where I add paragraphs to a multiline label whenever the user presses the enter key. Eventually the label fills with text so I have to clear the label to continue writing.What I need is a way to find how many lines of text are in my label, so after it passes line #50 I can make the label automatically clear itself and begin writing on line #1 again (as if the user just flipped to the next page of a book).My first idea was to turn AutoSize on and monitor the height of the auto-sized label box. After it passed a certain height I could clear it - but this didn't work because I need the label to be of a certain width.
View 14 RepliesI need to work with multiline textboxes. I am currently developing a web application that was started by someone else. The only problem I have is the text in my multiline textboxes is going to the next line before it needs to. I have played around with settings, removed the textboxes and added them back, and I am still having the same problem. When typing in the textboxes, the text moves to the next line after pressing the space bar.

View 10 RepliesThe following code selects a line ina richtextbox. It works OK expect from one problem:
When a line is biger than the size of the richtextbox, it wraps it. This create a big problem as I can not select the last line of the richtextbox (when a line is wrapped it becomes two lines). When I set wordwrap to off it works just fine
Private Sub RichTextBox1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles RichTextBox1.MouseMove

View 4 RepliesTo read any form's text (except RichTextBox) line by line I've always used this splitting
Dim Lines() as String = Split(TextBox1.Text, vbNewLine)MsgBox(Lines(0))This code just works perfectly.But whenever I try this code on a RichTextBox like this:Dim Lines() as String = Split(RichTextBox1.Text, vbNewLine)MsgBox(Lines(0))The message box appears with the whole lines.I think maybe the RichTextBox1.Text() returns another new line character (means not vbNewLine).
In a .NET 3.5 application, i want to get caret position in a RichTextBox control. The RTB is not XAML. Also, the RTB doesn't have CaretPosition property as described here: [URL] What is the simplest way using which i can get the caret position?
EDIT:To be more specific i want to find out what is the position of the caret from the start of the line on which it is positioned. I can get the line number by using GetLineFromCharIndex(rtb.SelectionStart) but not the offset from the start of the line.
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 6 RepliesI have two windows forms and I need to get the changing mouse position at the same time in the next form. I am using a function in the mouse move event to invoke the next form too ,so how should i properly do that
View 6 RepliesI am using VB.NET and I am currently having a problem accurately reading the mouse position. In my code, whenever the user moves the mouse, I want to have two variables store the mouse position's X and Y value, however when I move the mouse over an object such as a picturebox or a label, it will no longer give me the value until I move the pointer off the object onto the form. Are there any methods that will give me the absolute mouse coordinates regardless of whether the mouse is over an object or not?
View 9 RepliesI wanna move mouse postioin(100, 100) on the form. So, I use SetCursorPos(100, 100). but, the position is not of the form. It's the position of My screen. I want to set mouse position 100, 100 of the form T_T.
Can I get the mouse position of the form?
Now I got this "problem"... I'm making an application in Visual Basic 2008 Express Edition with some mouse options, and I was wondering... Do some of you have a clue on how to make the mouse go to on position, right click, move somewhere else, and left click, and then repeat it a X amount of times? The X should have the options to change its value.
View 1 RepliesI 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 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 RepliesI was wondering if there was some function in VB.Net that could change the mouse's position to a certain point, I found this code:

dim p as point
p.x = 100

A simple example is: lets say that im trying to make a program that allows you to move the mouse only with the arrows (left/right/up/down) how can i change the position of the mouse on the screen programmatically? If i wanted when you press a button the mouse to change position to X=0,Y=0 of the hole screen/desktop not the window of the form how can i do it? [Code]
