I want to add some text beside the text which contain "T" I have the same value below the line DETECT,ON but i just want to add text to the lines between FMAT,2 and DETECT,ON. Can i use indexOf methode to get the lines between FMAT,2 and DETECT,ON
The 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
RichTextBox1.Focus()

For now i used this code to add text
Dim filename As String = strFileName
Dim tfLines() As String = System.IO.File.ReadAllLines(filename)
If File.Exists("C:kaya.txt") Then

I want the text to be added to the T value above the line DETECT,ON. because this code add the text beside T whenever it finds the T value. how add line only between line FMAT,2 and DETECT,ON?
how can I get the lines which are have selected text in them?For example:The selected lines would be 1, 2,3 and 4 (0 being the first line)How can I get to code like:
For Each line as string(or integer) in textbox1."SelectedLines"
'Do something here for each line

I have a RichTextBox.
I want to input an integer and the RichTextBox to go to that line and delete all lines above it.
For example, if I have 100 lines in the RTB, and I specify "25" as the integer, I want lines 1-25 deleted and for the RTB to keep 26-100.
vb.net is SOOOOOOO annoying.i am drawing a list of lines to a control. So, I declare:Private Lines As New List(Of Line) Private CopyOfLines as New List(Of Line)In code, I have a custom Class called "Line".
I am wanting to reuse the list called "Lines" so I can start a new list while retaining the old list. So I copy it's contents to "CopyOfLines", then clear the contents of "Lines":
CopyOfLines = Lines
Lines.Clear
Problem is the contents of CopyOfLines ALSO gets cleared! Is there no way to break the connection of "CopyOfLines" to "Lines"? This seems so unnecessary. After all, if I say:
a=10
b=a
a=0
Then (b) will still = 10 while (a) = 0.
Why does vb.NET have to break such simple logic and turn it into a gargantuan issue? I wouldn't mind it as much if the MSDN library would make it possible to find references to "List (Of whatever)", but all I get are references to text in a textbox. It seems that every time I go to the MSDN, I get a convoluted, runaround explanation or simply no documentation of something someone has done in their own code? Where did THEY find the information?
On my form I have an Group Box that I use to visually segment various controls on the form. how can I add a horizontal line that looks the same as the border lines of the Group Box?

I just had this throw a compilation error while refactoring some legacy (hence VB.NET) unit tests, where I wanted to just comment out one of the sample inputs to MBUnit:

Is it actually treating the whitespace/commented-out line as an actual line? Generally, when I gripe about VB.NET, I preface it with, "Now, I wouldn't want to be the guy writing their grammar, but..." This seems like one of those cases where I don't know the answer, if I'm right.
I have a line of data that represent a data import. When the import is done, I would like to keep that exsisiting line, and add another line for the next import. So I have a display of mulitiple lines, showing multiple Imports.So this is one I have for the first section, it loops through the data so you see the rows incrementing
TextBox1.Text = clsDatRow.iFirstVal.ToString + " ROWS:" + iCountRows.ToString + " " + Date.Now.ToString
TextBox1.Refresh()
Now, I can I keep the line of data, and add a new line so for the next import, it does the same thing. It ried vbnewline, but it just clears that line, it doesn't move down to a next line.
I am suing VB 2008 express edition.
I am trying to solve this problem since many days. The problem seems to be rather mathematical, but I faced difficulties dealing with Grids and how to store them using visual basic.
[URL]
In my problem, I have a world of 200 x 200 units divided into 4 x 4 grids (Each of 50 units).
There is a line crosses some areas has the coordinates of Point A (Starting Point) of (XA = 12.43, BA = 159.48) and Point B coordinates (Ending Point) of (XB = 112.95, YB = 20.95).
The question is, how can find the length of (A to C1), (C1 to C2), (C2 to C3), (C3 to C4), (C4 to C5) and finally (C5 to B)?
In addition, how can I indicate the square in which the line is inside?
note that the method should work for all conditions (-ve and +ve line slopes) and for different A and coordinates.
Hey Overflow, I have an application which serves as a user interface for a spartan/command line program.
I have the program running on a separate process, and my application monitors it to see if it is responding and how mush CPU it is utilising.
Now I have a list of files in my program (listbox) which are to be sent to the application, which happens fine. But I want to be able to read text from the com-line so as to determine when the first file has been processed.
Com-line says one of "selecting settings", "unsupported format" and "cannot be fixed". What I want to be able to do is when it says one of these three things, remove item(0) in listbox1.
I thought of programming an event which handles com_exe.print or something or other, if possible.

I look at hundreds of VB.Net user interfaces through the internet and they all look horribly unsophisticated from a graphics point-of-view.Compare this to the backgrounds seen on tv broadcast that use blurred line gradients to create graphics that have some interesting appeal and draw the eye to them (at least my eye).I've attached some sample screenshot grabs below that I have annotated with magenta rects showing the interesting sections.What types of graphics routines can produce these types of graphic effects? The options that I have identified so far:
1.) More carefully done line smearing (see below..)
2.) Line drawing with a VB.Net version of the "Bresenham's line drawing algorithm"(as passel mentions in this post) (that might allow a specialized set anti-aliasing routines - like a wu algorithm).
3.) Line drawing with some Gaussian blurring as seen in the attachment to this post from my Perlin Noise thread.
4.) Possibly a gradient shaped by a vector GraphicsPath?
5.) Some other VB.Net gradient generating method?Possible the use of multiple passes with an alphafade brush?
6.) Last resort: manipulating the colors of individual pixels with lockbits marshal copying (highly undesirable).
I've done a fairly complete survey of whats out there on the internet for VB.Net samples for drawing lines to see if any of them combined line drawing with gradient effects and found very little.I played around with some code I found that did line drawing through mouse dragging and managed to achieve what I call the "line smearing" effect.I've attached my Line_Smearing_Demo below..As yet I have been unable to combine lines with shaped bezier curves,to produce Guilloche/Lissajous/complex Spirograph patterns like those seen on this page.

Problem drawing dotted path lines, with even dots along the path line.I want to draw a path line that can be any shape (square, round, outline etc), and along this path line I want even dots to appear.
I also want to be able to resize the shape (as in the example attached)This is very easy to do using "DrawPath" and defining points for the path and using a pen defined as dots.The problem I have is I want the dots to be evenly placed along the path, on any shape or size I draw.In the example I have created, I create a square with 4 points and draw a dotted path.There are 2 buttons that allows me to resize the square (larger or smaller) this helps show the problem more clearly.
The path starts at the top left corner and finishes back at the top left corner, the dots are evenly placed along the path, except the final dots at the end of the path. (Sometimes the dots are even and other times they are not even).The shapes I want to draw can be any size and any shape, but I have used a square in this example to show the problem I have. point me in the direction I need to go that allows me to draw the dots and give the impression that they are even all along the path, for all shapes and sizes.
In the pictures below if you change the size of the shape, one will have even looking dots, the other will not.

View 2 Replieshow to count the lines in textbox1.text (with multiplelines). I don't need to count each character. I only need to count each line from top to bottom in textbox1.text (multiplelines) and I will use Label1 to display the numbers.
example:

Obviously this is 5 lines and that's what I need to count.
