I am trying to get the webpage back as a string a used this in it own function. It comes back ip followed by <!--ipaddres (ipagine) --> I had the code done but my computer crashed and lost it all. If you get it as a string you can count the extra letters and and sub the extra ones then divided by 2 to get the half that will be the ip something like this:
*gethttp is the other function
function realIP as string
dim a as string
dim out as string
dim i as integer

I have a program I made that connects to a driver website at a timed interval to check for updates, but there are certain times where a CAPTCHA page comes up - I am trying to have my Timer stop if that page comes up, so I'm not constantly hitting it over and over - This is what I have, but it doesn't fire when the CAPTCHA page comes up:

I would like to read an HTML file, search each line to see if it starts with </head>. Then add the centering code after it. That line at destination file should read:
</head><table border="0" cellpadding="0" cellspacing="2" width="760"align="center"><tr><td>
After this I don't care to search for anything. Just read from source and write to destination. I know there are programs out there to find/replace text in series of files but I am not allowed to use external programs.

I have thios code that will load a php file (text file) into a sting via streamreader then its supposed to find and replace a portion of the text and write the changes back out to the file via streamwriter. I put my code together and after running it look at the file and it's unchanged. After looking closer it appears the problem is the find & replace operation I am doing on the string. Here is my code:

I've created a simple licensing system for a friend who has created visual basic programs which he sells at a few dollars each (they're speciality programs).The licensing system is coded in PHP (I'm a PHP coder), and the system requires the user to input their license key upon start up, if there is not already an activated key (which is created in a .txt doc)

I am adding a web interface (ASPX.NET: VB) to a data acquisition system developed with LabVIEW which outputs raw data files. These raw data files are the binary representation of a LabVIEW cluster (essentially a structure).LabVIEW provides functions to instantiate a class or structure or call a method defined in a .NET DLL file.I plan to create a DLL file containing a structure definition and a class with methods to transfer the structure.When the webpage requests data, it would call a LabVIEW executable with a filename parameter. The LabVIEW code would instantiate the structure,populate the structure from the data file, then call the method to transfer the data back to the website.
How do you recommend I transfer (copy) an instance of a structure from one .NET program to the VB.NET program that executed it?

What i am trying to do is save text from a number of text boxes to a user named file then subsequently be able to reload the data back into the same text boxes at a later date.so far i have this which was provided for elsewhere on the web, this allows me to save comma delineated data to a file which is fine but i can't seem to reload the data. As an experiment i have just tried to reload it back into a rich text box to see if the process would work but nothing as yet.
Private Sub SAveToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SAveToolStripMenuItem.Click
Dim savedfile As String
savedfile = TextBoxinc1.Text & "," & TextBoxinc2.Text & ","

I'm currently creating a web service that will allow the user to access a staff directory that is stored in an XML document format on a server. What I've managed to do so far is load my XML document into the server, convert the entire contents into a string and send it over SOAP to my client. The client successfully receives the entire content of the string. My problem however is that I'm finding it hard to find a technique that will allow me to convert my string back into an XML structure. I used a messagebox in the client to display the contents to make sure everything is received and all is well. Below is the code I'm using on the server side to convert the XML document to a string.[code]....

I have a TextBox and I want to allow VB syntax, but when I run the site and try to save the VB code to the database, I am getting an error. I believe the error has something to do with the VB code.I have put the httpRuntime requestValidationMode="2.0" setting in my web.config, and I've added validateRequest="false" in the directive at the top of the page, but it didn't resolve the issue.

This is my first time posting on the site, but I have found it very helpful in the past. I'm a self taught VB.NET developer and I have run across two questions.1) I'm working on a clients site to add a dynamic billing amount that is determined on what drop down list value is selected or what string gets input into the text box. I'm using nested case statements for this since it seemed a little easier, I'm also using two string arrays to hold my variables for use later on. Here is my question, since I am using strings for my variables do I need to convert them into integers to add them? I know the amp sign "&" is used for combining strings and whatnot, but does the plus sign "+" add the values together or combines them? I know if I convert the string to an integer then convert it back to a string that it will cause more processing to be done and I don't want that. What would be my best option in this case?
2) As for my second question, what's the best way to find an exact string? I have used InStr() before for small checks and it works just fine. But I was wondering if using str.Contains() is better suited for this task. From my understanding, InStr() looks for a relevance of the string you're looking for and str.Contains() looks a little more closely to better find what it is you're looking for. The reason I need to find an exact match is that if the user inputs 10 in the textbox, the code won't give them the price for 1. I have 4, 6, and 8 defined in the drop down list so I'm not worried about those. Would adding pound signs "#" around the string I'm looking for help narrow it down to only what I want?
As for the code, it's not completed. I just started it and began wondering on what was the best way of doing this. Private TUITION_COST As String() = {"900", "1800", "2700", "3600", "4500", "5400", "6300", "7200", "8100", "9000", "9900", "10800"}

I'm trying to convert a large array to a string, and then back into the array again after sending it over a network connection. No problems with that, but to keep my string as small as possible, I want to convert each array element into a single byte. I know that each element is going to contain a number no bigger than 100, so there will be no problems keeping them all 1 byte long. Problem is, I can't find the correct conversion commands. I think I should use 'Chr' to convert them into a string, but I can't work out how to convert that back into a number at the other end.

I've got the following simple code to convert Bytes to a Hex string :-
Code:
Shared Function BytesToHex(ByVal bytes() As Byte) As String
If bytes Is Nothing Then Return ""
Dim S As String = BitConverter.ToString(bytes)
[Code].....
The HexToBytes routine obviously can take a lot longer to complete than the BytesToHex routine and is noticeably slower when dealing with a lot of data. As I'm converting a lot of hex strings back to bytes, I wondered if there was a more efficient way of doing it without looping through the whole string as I am doing?

I have an application that monitors a set of opc boolean tags.When a tag changes from false to true (triggered), the application is supposed to query the database for data recording during a specific time period.I had the app done or so i thought until i realized that the background worker that i dimension to do the query is not firing the runworker completed event.at the start of the app, I create a new class for each trigger config in an xml file. Each trigger class has its own opc monitor and handle specific for that one boolean tag.If a tag changes to true a NEW instance of the query class is created.A new background worker instance is dimensioned to do the actual work.(this because there is a pre trigger query and a post trigger query which could be up to 24 hrs after the event has been "triggered" to true and the bg worker will wait until the required amount of time has completed before doing the post query).When the bg worker has completed, it should dispose of itself and all its managed resources.
The very first tag that changes to true will function as expected but when it is complete the RunWorkerCompleted will not fire. Everyone there after will operate as expected but not the very first one.I couldnt figure out why so I started commenting out some code.If I remove the line to create a new oracle connection, it works.

I'm trying to do some validation testing in VB.NET. If Entity.WeekEndDate.ToString = String.Empty Then ErrorList.Add(New cValidationError("id", "Incorrect Week End Date"))
Where WeekEndDate is of type Date. When I originally build the object, how can I insert a value into WeekEndDate that will generate an empty string(ie. "") when converted from a Date to a String?

I've built a string using the Format method:
Format("[{0}{1} {3}:{4}]", var1.ToString, var2.ToString, var3.ToString, var4.ToString)
var1 to var4 are long type. Is there a way to easily extract the information back (other then the String.Split method) ?
Like: MagicMethod("[{0}{1} {3}:{4}]", formatedString, var1, var2, var3, var4)?

I have been having some problems trying to decrypt the string returned back from SagePay.I used their asp.net kit which included the encrypt and decrypt functions using base64 - sending the information to SagePay is not a problem but I am having a number of problems trying to descrypt the string.Here is the function I am using to descypt:
Private Function base64Decode(ByVal strEncoded As String) As String
Dim iRealLength As Integer
Dim strReturn As String
Dim iBy4 As Integer

I don't think the web server is trying to encode anything as there are no + symbols within the url string and I have just glanced over the two to compair they are the same.This returns a blank string whereas when I use the sections commented out in the first loop i get a really weired string back and when I use their simpleXor function it just returns complete nonsense.

i want to type in a name to a textbox like type in "Ben" to textbox1. Then i want to click a button and have correlating numbers, say 126 show up in the textbox2. Im using a function to do this, how would i write a function that takes the string in textbox1, goes through each letter and sends back a numerical value for the letter through the function. I know how to do this with text files with stream reader, but don't know how to do this with strings.

I am looking for something that will convert a byte array to a string and back, anything in-build that does it as this method would:
To string:
vb
Dim b = ByteArrSerialize(Obj, Compress, EncryptKey)
Dim sb As New System.Text.StringBuilder
For Each item In b
sb.Append(Chr(item))
Next
To byte:
vb
Dim b(0 To Len(TheString) - 1) As Byte
Dim bCount As Long = 0
For Each item In TheString
b(bCount) = Asc(item)
bCount += 1
Next
