Hi guys I am trying to get the information on the active connection to listview.
So far I have:
Dim allProcess As String
Dim sl As String = "ProcessSplit"
Dim ipProps As System.Net.NetworkInformation.IPGlobalProperties = System.Net.NetworkInformation.IPGlobalProperties.GetIPGlobalProperties()
For Each connection As System.Net.NetworkInformation.TcpConnectionInformation In ipProps.GetActiveTcpConnections
Dim LEP As String = connection.LocalEndPoint.ToString
Dim REP As String = connection.RemoteEndPoint.ToString
Dim CState As String = connection.State.ToString
Next
How can I get a new row entry for every connection? Sorry I am just starting out. Thanks in advance.
Inside your For Each loop, just add the ListView adding code:
Dim data(3) as String
Dim itm as ListViewItem
For Each connection As System.Net.NetworkInformation.TcpConnectionInformation In ipProps.GetActiveTcpConnections
Dim LEP As String = connection.LocalEndPoint.ToString
Dim REP As String = connection.RemoteEndPoint.ToString
Dim CState As String = connection.State.ToString
data(0) = LEP
data(1) = REP
data(2) = CState
Next
itm = New ListViewItem(data)
ListView1.Items.Add(itm)

I have a folder with multiple text files in it, each text files has about 14 lines of text.
I would like to add all text files in that folder to a gridcontrol/gridview in vb.net.
My current code only adds 1 text file instead of adding all. any help would be greatly appreciated.

It is not necessary to declare the DataColumn array explicitly. It is created internally from the items in the braces.
You are throwing away your NewItem on each iteration. Why not add them to a list and add them all at once to a ListView.
You are reading the file over and over as you assign the LINE_ data. Read it once and use the resulting lines array.
You never use b and c in this code so I deleted them
I tested in with a .net DataGridView. The file io methods and the DataTable are the same.

I use below code to get first name, last name, email, and department from AD using VB.Net 1.1
Public Shared Function GetAttribute(ByVal username As String, ByVal pwd As String) As UserInfo
Dim objUserInfo As New UserInfo
Dim ObjFirstName As String = ""
Dim ObjLastName As String = String.Empty
Dim ObjEmail As String = ""
Dim objDepartment As String = ""
Dim Success As Boolean = False
Dim LDAPAddress As String = ConfigurationSettings.AppSettings.Get("LDAPAddress")
Dim Entry As New System.DirectoryServices.DirectoryEntry(LDAPAddress, username, pwd)
Dim Searcher As New System.DirectoryServices.DirectorySearcher(Entry)
Searcher.SearchScope = DirectoryServices.SearchScope.OneLevel
Dim Filter As String = "(samAccountName=" & username & ")"
Dim findUser As DirectorySearcher = New DirectorySearcher(Entry, Filter)
Dim results As SearchResultCollection = findUser.FindAll
Try
Dim Resultsx As System.DirectoryServices.SearchResult = Searcher.FindOne
Success = Not (Resultsx Is Nothing)
findUser.PropertiesToLoad.Add("name")
Dim name As String = DirectCast(Resultsx.Properties(name)(0), String)
Dim de As System.DirectoryServices.DirectoryEntry = Resultsx.GetDirectoryEntry()
Dim gg = de.Properties.PropertyNames()
For Each Onn As String In gg
Dim str As String = String.Format("{0}", Onn)
Next
Try
ObjFirstName = de.Properties("GivenName").Value.ToString()
ObjEmail = de.Properties("mail").Value.ToString()
ObjLastName = de.Properties("sn").Value.ToString()
objDepartment = de.Properties("department").Value.ToString()
Catch ex As Exception
ObjFirstName = de.Properties("DisplayName").Value.ToString()
End Try
But I can't get those attributes. in
Dim str As String = String.Format("{0}", Onn)
there are only 15 attributes, and there are no firstname, lastname, email, and department. What am I doing wrong?
Your code, though old-fashioned, looks fine on first sight. If you insist to continue with your code, I'll have a look later.
In the meantime, this code should fit your situation:
Dim user As DirectoryEntry = New DirectoryEntry("UserDN")
Dim src As DirectorySearcher = New DirectorySearcher(user, "(&(objectClass=user)(objectCategory=Person))")
src.PropertiesToLoad.Add("sn")
src.PropertiesToLoad.Add("givenName")
src.PropertiesToLoad.Add("mail")
src.PropertiesToLoad.Add("department")
Dim res As SearchResult = src.FindOne
Console.WriteLine(res.Properties("sn")(0))
Console.WriteLine(res.Properties("givenName")(0))
Console.WriteLine(res.Properties("mail")(0))
Console.WriteLine(res.Properties("department")(0))
Console.ReadLine()
i have this string
Dim test As String = "12,32,12,32,12,12,32,15,16,15,14,12,32"
and want to retrieve a string
newstr = 12,32,15,16,14
i tried this much
Dim test As String = "12,32,12,32,12,12,32,15,16,15,14,12,32"
Dim word As String
Dim uc As String() = test.Split(New Char() {","c})
For Each word In uc
' What can i do here?????????
Next
only unique numbers how can i do that in vb asp.net
right answer
Dim test As String = "12,32,12,32,12,12,32,15,16,15,14,12,32"
Dim word As String
Dim uc As String() = test.Split(New Char() {","c}).Distinct.ToArray
Dim sb2 As String = "-1"
For Each word In uc
sb2 = sb2 + "," + word
Next
MsgBox(sb2.ToString)
Dim test As String = "12,32,12,32,12,12,32,15,16,15,14,12,32"
Dim uniqueList As String() = test.Split(New Char() {","c}).Distinct().ToArray()
Dim test As String = "12,32,12,32,12,12,32,15,16,15,14,12,32"
'Split into an array
Dim testArray As String() = test.Split(",")
'remove duplicates
Dim uniqueTestArray As String() = testArray.Distinct().ToArray())
'Concatenate back to string
Dim uniqueString As String = String.Join(",", uniqueTestArray)
Or all in one line:
Dim uniqueString As String = String.Join(",", test.Split(",").Distinct().ToArray())
Updated Sorry I forgot to add the new string together
Solution:
Dim test As String = "12,32,12,32,12,12,32,15,16,15,14,12,32"
Dim distinctArray = test.Split(",").Distinct()
Dim newStr As String = String.Join(",", distinctArray.ToArray())

You forgot to put parentheses for Distinctand ToArray. Because these are methods
Dim uc As String() = test.Split(New Char() {","c}).Distinct().ToArray()
I want to access contents of a catagorized view of lotu notes in .net.... can some one help me regarding this.. I am using interop.domino.dll.
Dim s As New Domino.NotesSession
Dim txt As String
Dim key() As String = {"abcd", "abcd"}
s.Initialize("")
Dim ldb As New NotesDatabase
ldb = s.GetDatabase("", "", False)
Dim vw As NotesView
vw = ldb.GetView("Project Module Wise Configurable Item")
vw.Refresh()
Dim entry As NotesViewEntry
Dim vc As NotesViewEntryCollection
vc = vw.GetAllEntriesByKey(key, False)
entry = vc.GetFirstEntry
While Not (entry Is Nothing)
txt = CStr(entry.Item)
entry = vc.GetNextEntry(entry)
ListBox1.Items.Add(txt)
End While
try:
Dim s As New Domino.NotesSession
s.Initialize("")
Dim ldb As New NotesDatabase
ldb = s.GetDatabase("", "", False)
Dim vw As NotesView
vw = ldb.GetView("Project Module Wise Configurable Item")
vw.Refresh()
Dim txt As String
Dim entry As NotesViewEntry
Dim vc As NotesViewEntryCollection
'declare the array
' ---- edited -----
Dim key(1) As variant
'----edited ---
key(0) = "abcd"
key(1) = "abcd"
'be carefull with the second parameter 'false'
vc = vw.GetAllEntriesByKey(key, False)
entry = vc.GetFirstEntry
While Not (entry Is Nothing)
txt = CStr(entry.Item)
entry = vc.GetNextEntry(entry)
ListBox1.Items.Add(txt)
End While
What worked for me: Declaring key as array of object.
Dim keys(0 To 1) As Object
keys(0) = "asdf"
keys(1) = "sgdk"

I am trying to nail down free space on a remote server by querying all the drives and then looping until I find the drive I am seeking.
Is there a better way to do this?
Dim oConn As New ConnectionOptions
Dim sNameSpace As String = "\\mnb-content2\root\cimv2"
Dim oMS As New ManagementScope(sNameSpace, oConn)
Dim oQuery As System.Management.ObjectQuery = New System.Management.ObjectQuery("select FreeSpace,Size,Name from Win32_LogicalDisk where DriveType=3")
Dim oSearcher As ManagementObjectSearcher = New ManagementObjectSearcher(oMS, oQuery)
Dim oReturnCollection As ManagementObjectCollection = oSearcher.Get()
Dim oReturn As ManagementObject
For Each oReturn In oReturnCollection
'Disk name
Console.WriteLine("Name : " + oReturn("Name").ToString())
'Free Space in bytes
Dim sFreespace As String = oReturn("FreeSpace").ToString()
If Left(oReturn("Name").ToString(), 1) = "Y" Then
Console.WriteLine(sFreespace)
End If
Next
Why not just make your WMI query only pull back where name='Y'?
So:
Dim oQuery As System.Management.ObjectQuery = New System.Management.ObjectQuery("select FreeSpace,Size,Name from Win32_LogicalDisk where DriveType=3 AND name='Y'")
