DnsGetHostEntry takes an IPaddress as an argument but the one I'm supplying it while debugging is throwing an exception of "No such host is known" when I know that this is a perfectly valid host.
Somehow a space or character has been introduced at the beginning of the strong as per the text in quotes below. I tried a Trim(" ",

View 2 RepliesI am trying to write a function for determining the data type of columns in a delimited file.However my function is not detecting a newline and exiting the loop after the end of the first line.* 'del_2' is equal to a new line character, i have tested this using a small bit of code
if del_2 = ControlChars.NewLine then
MessageBox.Show("It is a newline")
end if
and got the message, and i know the newline characters are at the end of each line in 'filecontents' as i am adding them manually.

I'm using the Oracle command dbms_output.get_line to retrieve output from a stored procedure. Once my code runs the command, I'm retrieving the results through a buffer string, 32000 bytes long.Inevitably, this string will have Oracle line breaks (chr(10) and chr(13)) in it that I'd like to replace with Environment.NewLine so I can display the output in a standard Winforms textbox.Here is the code I've been using - I don't recall exactly where I got the Oracle command right now, but if I find it, I'll add the link.
Dim cmdGetOutput As New OracleCommand("declare " & _
" l_line varchar2(255); " & _
" l_done number; " & _

View 2 Repliesprogram makes strings from webbrowser documenttext.For example
String1 = "<span class""long-title"" title"" Informations here"
Im trying to remove all text before "Informations here" this is what i currently have.
dim mychar as char () = {"<"c, "s"c, "p"c, "a"c, '....thatandlike20moretill.... "e"c, """"c}
string1 = string1.TrimStart(mychar)
(Note that each letter or symbol inbetween the quotations is a part of the string (span = "s" "p"...)Now this works. Not all the time though and its a pain in the .. having to do "letter"c, all the time.. (I got over 10 strings lol) Im wondering if theres a way easier method to remove part of string from the beginning, maybe like still a certen part of the length..
Basically I have a webresponse stream:dim lol as string = readstream.tostring there is a lot of information within the string but only one link starting with http: located near the end of the string - however there is no constant character point where I can start... (i.e. 38)
I want to extract the link from the string i.e. dog cat plane car [URL]..that is approximately how it looks above - words and url substituted I want to just extract [URL]..I had an idea of parsing the string from http: to the end Then after that splitting the string up again to remove the }], however it does not return anything
Currently I have this code in my app:
Dim parts As New List(Of String)(ListBox2.SelectedItem.ToString.Split(""c))
Dim myArr(1) As String
myArr(0) = parts(0)
parts.RemoveAt(0)
myArr(1) = String.Join("", parts.ToArray)
MsgBox(myArr(1))
MsgBox(myArr(0))
As you can see it splits from left to right.Can anyone help me update the code to read the string RIGHT to LEFT and remove everything read till it finds the FIRST "" and display in msgbox?
I need to remove some content from string.
dim id as string ="TabContainerContent1_Basic_MyFirstName"
I need to remove TabContainerContent1_Basic_ . The fix is TabContainerContent1, it is under loop so always _Basic_MyFirstName will be changing. I need to get the text after the last _ char.
How would I remove before a string e.g. If I wanted to removed before "the" in "this is the test" it would leave me with test.

I have a string with 60000+ characters. I look for informations inside the string in a sequentially order. Every time I found a information I delete whatever is behind that information. In other words I reduce the size of the string every time I find something, and I do this using IndexOf and Remove, much like this:
vb.net Str = Str.Remove(0, Str.IndexOf("MyInfo"))
This can be quite heavy on the processor. So my question is it faster to look the informations using Regex or it would be about the same?
I have this sample code...
Private Sub DataReceived( _
ByVal sender As Object, _
ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) _
[code]....
this displays in a text box the received data from a serial port. And it works like a charm but the data received has custom start and end of line characters. A line begins with chr(&H2) and ends with chr(&H3). What i want is on the text box those characters to be hidden and the chr(&H3) to start a new line.

I have some questions about arrays.
1) Lets say I open a file in a byte array and I need to add 5 bytes of data at the beginning. How would I go in doing that? ex: attaching to arrays together.
2) How would I go in adding 1 byte of data in a bye array?
All i need to do is open part of a file in bytes. Add a letter and 2 numbers to it at the begging and a number at the end.All i need to know is how to attach 2 byte arrays together and how can u add a byte of data to an array.
my problem is how can i convert the 63 in the beginning of the number ex."639063100343" and change it to 0 ex."09063100343"

Is the code I have that works but What would the IF statement be to check if it is empty? String.empty and "" don't work because I think it sees the mask as characters.

For each character of this string I want a new character out of the string and then remove the character from the list of characters that still maybe used for other characters. It may not get the same character, you could basically just call this encryption, but it's not what I am making. I don't want to waste my time doing this one hour while VB can do this for me in <1 second.

I'm using a richtextbox in vb.net. I need to maintain the text formatting while inserting a new entry.I have this issue solved although I am having difficulty with getting a new line between my new text and the prior existing text.Most solutions online presume you're working with rich textbox. text which accepts controlchars.lf, vbcrlf, and chr(10)... even chr(13) adds one single newline.How do i get the newline in rtf formatting?I prefer to have the new text entered at the top of the richtextbox as a user should see the latest update first.In addition, if this can be done more elegantly, I'm open for suggestions.Where you see controlchars.lf is where I want an rtf-based new line to show up.
