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

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()

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?
I have a GridView with image buttons for selecting rows. I am using an OnRowDataBound event to color selected rows Blue:
e.Row.ForeColor = System.Drawing.Color.Blue
Now that works great as long as I don't set a color either in the CSS stylesheet or on the grid Items themselves. If I do that, then all rows are colored that color and I don't get my Blue selected rows color for selected rows. I would like to color the text in the grid something other than black.
I have say... 10 lines of text in listbox1. how can I copy lines 5 thru 10 to listbox2 on buttonclick?
View 4 RepliesI 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?

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.

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'm currently use visual basic 2008. The problem is I have try this code but,it produce no output. There is no problem with the code I guess. Here is my code

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.
