[2008] Reading A String Content From URL
Mar 10, 2009
i have a webrowser and i need to find about 10 links all begining with [URL], from the html code of that site. The websites in the code wont be clickable, they are usually listed on a forum. The end of the link above can be diferent, so im not sure how you could find the end point. No assumptions can be made as to the code that will be after the link, as every website is different. The link then needs to listed in a listbox for further processing.

I looked everywhere online and I couldn't locate an equivalent VB2008 code for this php code.
$field = mysql_fetch_assoc($result);
$field_title=$field["title"];
I'm trying to read the content of a field in a mysql database. I found this code below that does it but you must select the position of the field (column 0, 1, 2 etc) myData.GetString(1) instead of the name of the field. In the php code above it is "title". I'm looking for a command like myData.GetString("title")
Dim myCommand As New MySqlCommand
Dim myAdapter As New MySqlDataAdapter
Dim myData As MySqlDataReader

I already know the basic procedure of how to read specific cells of an .xls file using VB.NET but I can't figure out how to automatically get all the data from such a file.Basically, I'm obtaining the data like this:
Dim xlApp As Excel.Application
Dim wb As Workbook
Dim ws As Worksheet
xlApp = New Excel.Application
[code]....
In this case, I know that there will be content in the first 10 rows of the columns A, B and C but what would I have to do if I had a huge document whose size and content might even change from time to time? I know that there is also an attribute ws.rows.count but this always returns a big value like 60000 even if only a few rows are occupied.So basically, I'm looking for a simple way to loop through all the used rows of an Excel file with the possibility of accessing each cell in that row.

My app currently sends GET httpwberequests and parses the content after reading the response stream for each request and the repeats this process over and over. I need to implement a continuous http stream which uses the same GET request but the connection stays open, from what I understand. how would I change my existing code to do this?

I am trying to create a console application that allows me to read the contents of a text file and saving the data by specific name in a set of files. For example, the text file I am going to read is a tab delimited file. Some content of the file includes full name, school, location, and whatnot. I want to save the content by school name in a set of files that have the school names. In this case, everyone that attends "Central" will be saved in a file named Central.txt.Everyone that attends "Central Park" will be saved in a file named Central Park.txt.These are the sub procedures I came up with so far:
Readfile()
'Use StreamReader
WriteFile()
And I think I am on the right track of reading the text file:
Dim objStreamReader As StreamReader
Dim strLine As String
'Pass the file path and the file name to the StreamReader constructor.

I want to read a tab delimited file so i set up a data reader with the following connection string: [Code] However when I do this it doesn't seem to delimiter at the tab characters (I cannot work out why it is breaking up the data where it is). the first few lines of the csv are in the attached "dbamstr.txt" - the select statement I am running is: "SELECT * FROM dbamstr.txt".

My program so far reads a certain webpage's source code and places it in a textbox. This much has already been accomplished.
Now I need to pick certain strings out of the rather large amount of text data and have the lines stored in variables, but the trick of it is, the exact string is unknown. The exact function should be, that the code finds certain tags from the source code, say <td> and </td> and takes the string data in between those tags, what ever it may be.

I have a string which is xml data which is very nicely indented and well formed. Dim xmlstring as string I am trying to pass the above mentioned string to a Java Web Service but the input parameter datatype is string array. I am converting the string to string array as shown below localws.receiveNotification("TestQueue", xmlstring.ToString().Split(CChar("")))
As the datatype for the input parameter in the above webservice is string() array for some reason my XML data is getting messed up and lot of elements are breaking and appearing in two lines and my xml data is no more well formed.

I've two Strings which I'm loading from a SQL Server 2008 database (nvarchar-field)After loading them from the database Visual Studio 2010 displays them as follows in the watch window:
str1 = "Test"
str2 = "Test"
But the comparison with str1 = str2 returns False If I write those strings to a file with UTF8 Encoding the result is as expected:
Test
Test
If I write those strings to a file with ANSI (Default) Encoding the result is NOT as expected:
?Test
Test
Converting the strings to bytes:
System.Text.Encoding.Default.GetBytes(str1) 'Returns ByteArray {63, 84, 101, 115, 116}
System.Text.Encoding.Default.GetBytes(str2) 'Returns ByteArray {84, 101, 115, 116}
System.Text.Encoding.UTF8.GetBytes(str1) 'Returns ByteArray {239, 187, 191, 84, 101, 115, 116}
System.Text.Encoding.UTF8.GetBytes(str2) 'Returns ByteArray {84, 101, 115, 116}
Where is the Byte 63 in case of ANSI Encoding OR Bytes 239, 187, 191 in case of UTF8 Encoding for str1 coming from?Well, Bytes 239, 187, 191 are the BOM for UTF8. The question here would more likely be: Why do I get the BOM for str1 but not for str2?(Well, the values are values passed to a webservice which inserts them into the database, the initial values are passed to this webservice by a client I've no control over)

I've been working on this RegEx for the past day or so and I think I have it worked out so that it returns the data I want. First a little background.I have a content editor that users will be able to edit web pages. They can format text, add links, etc.. standard content editor stuff. When they click save, the editor provides the ability to get the content (editor.Content) and put it into a string. What I want to do is get any links (<a> tags) and find out if they are internal or external links and if they are PDF files.
Here is the Expression I've come up with:
<a[^<>]*hrefs*=s*[""'](?<domain>https?://[^/s'""]*)*/?(?<path>/?[^s""]+?)?[[>""']
With this, I am able to separate the domain (if it has one) and the path out. Then, I loop through the matches...
dim matchColl as MatchCollection = Regex.Matches(editorContent, regExString)
For Each m as Match in matchColl
If m.Groups("domain").value <> myInternalDomain and m.Groups("domain").value <> "" then
'this is an external domain... do some stuff
[code]....
My question is this... the parts where I 'do some stuff' to the values, what would be the best way to get that back into my 'editorContent' string? I could probably put the editorContent into a StringBuilder and do a whole bunch of replaces on it, but is that very efficient?So, for example, with the PDF, I want to specify that it open in a new window (target="_blank") and for the external URL, add some javascript code into the onclick attribute.

But when the tool needs to check more then 5000 links, he will do it very, very slow. He can be busy for like two days. The process of downloading the content of the filehosting link, and checking it are all in a backgroundworker. The follow code I used for downloading the content from the link:
download content from url
Function get_content_from_url(ByVal url As String) As String
Dim Str As System.IO.Stream

OK, I have setup a "bug report" that will e-mail all necessary details about the application I have, I want it to be as easy as a click of a button. The only problem is the e-mailing part, I don't quite understand what to do. Is it possible to launch a web page from VB that can have code added to it, to write and send the e-mail, I always remember sending e-mail's through PHP easy.

I'm making a calculator that would read a "string" from a textbox and parse it and follow Order-of-Operations/PEMDAS on the string. I have a couple of questions:
1) What would be the best way to parse the code so that it won't just take a "left expression" and "expression" and perform the operation on those 2.
2)How would I be able to make is so that 0 is considered valid, but prevent a 00 or 020 or 002 to be inputed.
