I would like to search a webpage for a value in the left column of a table, then pull the value from the right column as my result. In a Visual Basic Forms Application.
the data is listed in a table, for example...
abc 123
def 234
ghi 345
jkl 456
and if i just want the value of ghi ( I know "ghi", but i want the goal of the code to find the "345")
How would i go about pulling text from a web page using webbrowser 1 and having it update in a timer displaying the viewer count in a label.

I Can make it recognize id="channel_viewer_count" but it's not showing the viewer count in the label.
I finished every piece of code in my program save for one tid bit, how to pull two numbers from a text file. I know how to pull lines, I know how to pull search strings, but I cant figure out this one to save my life.[code]The two numbers that I need out of this are the two ones that I put in the **'s (the asterisks are not normally there). These numbers will be different every time this sheet is generated, and the number placement might be different as well as some of the numbers could have 4 digits, 5 digits, or 6 digits.

FirstName

If the record does exist then I want the Phone number to appear in a separate textbox which is named txtPhoneN. I have included the code I use to connect to the Database. I have already managed code the part to Add new record to the database.

I came to a company that already has a fully grown project... but coders that worked here before me didn't follow conventions and didn't use parametrized SQL queries... as a result there is over 1000 places in a very huge project that can possibly be vulnerable to SQL injection...
I need to find a solution that will automatically detect if there is an SQL injection in the code. So, for example there is a form which allows user to enter comments regarding a product, which will be sent to database on submit... how can we make sure that a user didn't enter a harmfull query instead of a normal text?
Is there any advanced code/regular expression/magic that can detect if this text contains a piece of SQL query instead of normal harmless text? I will accept any links, pieces of code in any language or even commercial software that will do that for me.

View 8 Repliesi need to copy the text from a webpage into a txt file which will then be copied into a txtbox on my form (this parts done),the web page url will always be the same and the page will contain just a line of text that will chage from time to time
also i need it not to update the text file if the page displays "page cannot be displayed"i think the best way to do this is if i always start the website text and end the text with a certain "very random" word like "websitedownload" this will never come up anywhere elsealso if it doesnt copy unless the url is exactthis will stop default search engines kicking in.the website is mine/company's so this i can do

View 1 RepliesI was wonder how, if you can, can I create a WebBrowser control or something similar to this, that will contain a selected area of information, and that information only. So it doesn't load and show the whole web page, only the part I choose.
For example, I would only want to show the weather portion of this webpage: [URL]

I am trying to pull sql data into a text file. The code works just fine, until some new data comes in from lazy employees and a couple fields (used for notes/comments) are now left blank. Originally I've never seen them blank so I didn't think anything of it.
col2 = myreader.GetString(1)
It will error if the field is ever null - I even tried using a case when:
case when note is null then '" & empty & "' else note end and set the variable emtpy = '', but vb still thinks that it's null and errors?
I'm building a vb project using vb 2008 and I am trying to get a specific data from the source of a webpage. I am now trying to have the vb project access the below source of the webpage [URL] and retrieve the word "Dublin" from the code from the following line:
</tr><tr><td class="s7 li ou"><a href="dorf1.php?newdid=106467">Dublin</a></td>
The word "Dublin" should be stored in the string villagename1 (I will use that string several times later in the project) and it should at NO time open a IE page as to make it as invisible as possible.
Webpage Source:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "[URL]">

I am creating a simple researcher application to access and store data. As of today it workes by entering a number into a text field and hit enter/button. The result then shows up in a non-menu webbrowser window. What i would like it to do was to exclude the web browser window, and instead show in a popup window inside the application. This should be rather easy, here's what i think might be a problem. I want only to show specific lines from the webpage, not the whole page.
View 3 RepliesI have used .NET and ShDocVw for years to grab data off webpages without any issues I couldn't overcome. This website has me beat though. It seems like such as easy task to grab the titles and other information off a library search page, but I can't see the data to be able to grab it. Usually, I just look in the DOM, but the data wasn't there. I did a view source, but the data wasn't there.
View 1 RepliesIm trying to come up with a do while statement that reads through a text file till the end while pulling out 3 different matched items, then writing those matched items to ascending spots in an excel file, and then creating a bar graph according to the saved data. Sounds complicated but...I have the program reading the text file, pulling out the first iteration of all three, writing them to an excel file, and I have it even graphing them the way I want it to. The only thing I havent done before (and which is probably the easiest), is creating the do while statement so it keeps searching line to line for the three interactions of what im looking for and writing them to ascending spots in the excel file.
Right now my code works like this, which is perfect for pulling out the first 3 and creating a graph, I just inserting a do while and a rowindex + 1 variable.
vb Dim alines() = System.IO.File.ReadAllLines("C:deviceinfo.txt")
Dim amatch As String
Dim muvalue As String
[CODE]................
I have a feeling in order to pull this off, I do not want to use the, "ReadAllLines" option and possibly want to put the text into an array.
And do something like: if lines.count > 0
But im not familiar with how arrays work in VB, and more specifically what the syntax is. The other tricky thing I am trying to add is an if statement that adds to a variable (such as i) everytime a line is added to excel so the program will write to ascending lines. I was trying to have the it work with the do while statement but pretty soon realized that if I did: i = i +1. Everytime it went through the loop then the data was going to be on random lines corresponding to their place in the text.
