VS 2010 Extract String From Byte Array Or Memorystream?

Jun 16, 2012

I'm using WinPcap to capture incoming data. Basically I'm dealing with a continuous stream of incoming data, either as byte array or as memorystream (pieces up to 64kb).

I need to check this data to see if there's a certain url and then extract it.

The url I need to find looks like this:http://201.122.38.5/data/today/798572987-589571?139805890582 The length of the 'code' after "/today/" is always the same. The IP address changes. What's the best/fastest/most efficient way to continuously check these byte arrays or memorystreams and extract the urls without hogging the CPU too much?

.net - Shortening A Repeating Sequence In A String?

Jun 30, 2010

I have built a blog platform in VB.NET where the audience are very young, and for some reason like to express their commitment by repeating sequences of characters in their comments.

Examples:

Hi!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3
LOLOLOLOLOLOLOLOLOLOLOLOLLOLOLOLOLOLOLOLOLOLOLOLOL
..and so on.

I don't want to filter this out completely, however, I would like to shorten it down to a maximum of 5 repeating characters or sequences in a row.I have no problem writing a function to handle a single repeating character. But what is the most effective way to filter out a repeating sequence as well?This is what I used earlier for the single repeating characters

Private Shared Function RemoveSequence(ByVal str As String) As String
Dim sb As New System.Text.StringBuilder
sb.Capacity = str.Length

Why Is String Returning A Char

Jun 27, 2012

I have built a DataTable from my database. Then I am looping through the rows and trying to access a string, however the value is being returned as each character in the string.

For Each theseRows In DisplayForm.MainTab.Rows
If theseRows.Item("Last_Name") = userLast And theseRows.Item("First_Name") = userFirst Then

[Code]....

The Trap_Code values are two or three letter strings, the returned value is each letter once at a time. The loop seems to cycle through the individual characters of the string as an array rather than display the entire value, which is what I was hoping for.

Using Char - First Letter Of String Must Be Certain

Apr 18, 2010

Basically the first letter of a string must be a certain letter. At the moment the only way I know how to do it is as follows:
If sConsignmentNo(0) = "J" Or sConsignmentNo(0) = "C" Or sConsignmentNo(0) = "U" Or sConsignmentNo(0) = "N" Or sConsignmentNo(0) = "H" Or sConsignmentNo(0) = "S" Or sConsignmentNo(0) = "V" Then
Basically listening the same thing out over and over. Is there a way I can say, If sConsignmentNo(0) = ListOfValidEntries i.e J,C,U,N etc?
Using Visual Basic 2008 and cant use regex!

Import And Call Unmanaged C Dll With Ansi String "char *" Pointer String From .net?

Mar 11, 2010

I have written my own function, which in C would be declared like this, using standard Win32 calling conventions:int Thing( char * command, char * buffer, int * BufSize);I have the following amount of VB figured out, which should import the dll and call this function, wrapping it up to make it easy to call Thing("CommandHere",GetDataBackHere).UPDATE:This code is now a working solution, as shown here:

Imports Microsoft.VisualBasic
Imports System.Runtime.InteropServices
Imports System
Imports System.Text

[Code]...

Updates: I got the code to build by following the help received here, and then I had forgot the As Return Type (which got me a MarshalDirectiveException PInvokeRestriction). Then I had an assertion failure inside my DLL, which lead to an SEHException. Once fixed, this works BEAUTIFULLY. There are newsgroups where people are saying this can not be done, that VB only loads managed dll assemblies (which I guess is the normal thing most VB users are used to).
