I'm trying to retrieve some values from my website and put them in a variable or textbox. The source on the website always looks like this: [Code]. I only want to retrieve the first line though (the rest is some stuff my webhost automatically generates). [Code]. But this doesn't work properly :S In above example it would return the whole string, except the last two characters. What do I need to alter to make it work correctly?
Is it possible to (programmatically) retrieve the current line of code being executed? For example, I have program X that's only 200 lines long. Is it possible to tell a user "The current line of code is: ....."?Mods - Please do not mark my posts as answered. It is extremely rude. You have no idea if you've answered my question.
I WILL come back and mark the ones that are answers, as answers.
I'm trying to retrieve line number 5 - 8 from a text file, but I can't figure out how. I can retrieve a single line and I can retrieve all lines, but I can't figure out how to get those specific ones. I tried using substring but it didn't work.
I have a program that searches for a word in a .txt file. When it finds the word I want to print the following 5 lines under that word. So for example: I search for "juice", and my label grabs this out of the textfile: juice apple grape orange milk Is there anyway to this in VB.NET?

How would you go about searching a webbrowser for a line containing a string? Here is my code so far:
Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim url As String WebBrowser1.Navigate(txt_url.text) [Code] .....
In this code, I would like to search for the first instance of "RichTextBox.AppendText" and put that into a string. I have also found when browsing in the webbrowser if you can across a download, and you just want to download it to a default directory without the open, save, cancel dialog box coming up. How would you go about doing this, if it is possible?
I would like for my program to open up a new form (It will be in Form4 webbrowser) and the form will navigate via the text line that was double-clicked in a RichTextBox1. Here is an illustration showing what I'm trying to accomplish:
Here is the code that I have so far:
Private Sub RichTextBox1_MouseDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles RichTextBox1.MouseDoubleClick Form4.Show() Form4.WebBrowser1.Navigate("http://www.google.com/search?q=" & "THIS IS THE AREA OF CODE THAT I NEED TO MAKE THE RICHTEXTBOX1 CLICKABLE!!!" ) End Sub
what i need to do is open a txt file, read line by line, decode each line into an array and display. Now all works ok apart from one line.
sTextLine = objReader.ReadLine() <-- Value of string cannot be converted.
full code here ------------- Dim objReader As New System.IO.StreamReader(sOpenFile.Text) Dim sTextLine As New ArrayList() Dim sText As String = "" Dim i As Integer = 0
How would i go about reading a file Line by Line that within that line The values are delimited by " Example of the data:
"bob" "cat" "1243" "steve" dog" "6789"
I've started this with this code but not sure how to go about the next stage:
Using MyReader As New _ Microsoft.VisualBasic.FileIO.TextFieldParser(My.Application.Info.DirectoryPath & "Records28112011.jd") MyReader.TextFieldType = FileIO.FieldType.Delimited
I am trying to read in a TextBox line by line and take the first 7 characters of each line and output everything in another TextBox.This is what I have so far.

i need the app to preview the line in textbox in timeintervalof 1 s (can be change)nd when it will reach to the end it close the text file and andreread it after let say 1 m ..

how can i make my webbrowser open up a new link in my same webbrowser or in another form? basically what im saying is i dont want it opening links in internet explorer.
I am writing a few web based apps which will require a webbrowser extension. I have already used the IE webbrowser control that uses the trident web rendering engine. I believe this is MSHTML.DLL? Anyway, some of the users of my programs have complained of a few things. Particularily,
1. It seems to be a slow browser, at least compared to other rendering engines out there (webkit and gecko are 2 known ones).
2. On the developer side, it seems to be low in features. The features are sufficient in most cases, but there are some "special" things that I need.
3. It has VERY low HTML (and especially HTML5) compliance.
My question is, how much work would it take to use a different engine (such as webkit .net, which I HAVE heard of) and be able to distribute it easily. Or, if you guys feel ambitious, we could try writing a brand new engine ourselves. I know how big of a job it is, and frankly, I have no clue where to begin. I would just like your thoughts and opinions on the matter.
I am utilizing a webbrowser control in vb.net 2005 to display excel workbooks
We are using this control to open excel documents. Webbrowser.ShowSaveAsDialog() allows the user to save the excel workbook open at any location he wants
However, I don't want the user to decide where to save. Is there any way to save an excel document from the webbrowser control without going through the ShowSaveAsDialog?
On closing of webbrowser, a simple prompt to user whether he/she would like to save changes should be fine enough
As of now, I can close webbrowser control and it does not prompt the user to save the changes. Actually, all changes are lost until and unless I perform a save (Ctrl+S) manually
i have created an app to load an access database into a datagridview, which contains web urls. When button is clicked it webbrowser1 navigates to each url and each webpages document.inertext is put into textbox. This all work fine but after a while the webbrowser navigation becomes increasingly slower.
For Each RW As DataGridViewRow In Me.DataGridView1.SelectedRows '''''''''''#######cell values into strings ########'''''''''''''' If RW.Selected = True Then Dim domain As String
I want to make a webbrowser, but only have it show one specific thing and not the whole page. The thing I want it to show and only show is in about the middle. How would I frame the page, and put it on the webbrowser?
a user copies multiple lines of text (say, from an email) into the clipboard. Based on my observations, when one tries to paste the text into a single-line textbox, only the first line is actually pasted in. (I am aware that the "obvious" solution would be to set the Multiline property to True, but there are reasons I am looking to avoid this and to put multi-line data into a single line.)
In the TextChanged event handler, I wrote code that parses the clipboard data to successfully convert it to a single-line, comma-delimited format.

I'm trying to read a file line by line into an array but It skips the item at index:3 I have it msgboxing just to make sure and it wont even touch it.

I am using WebBrowser1.DocumentText to get a websites source code, and then parse a string. I am trying to view the source line by line, and doing it as follows:
[Code]...
However what is displayed is each character from the source code, rather than the line. I am making the client log into a website, and the needed value from the source code is then parsed, so I need to use the WebBrowser type to get the source code.
I have a picture in my picturebox. In that picture, I need to draw a straight line between two points and calculate the length of that line (probably in pixels). Is there any suggestion how to do it?
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
