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"

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'm getting an error everytime I try to upload a XML file to an specific server.
It returns "Invalid character in a Base-64 string". Here the code I'm using to sign:

Is there something else I should add to the code?
The manual tells me to follow the instructions from https://www.w3.org/TR/xmldsig-core/
Turns out it was a line break when saving the document. I set the .PreserveWhitespace property to true before saving the .xml file and not it seems to be working.
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()
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)

Try setting up a subscription via the Report Manager and specifying the Report Delivery Options value for 'Delivered By:' as 'Report Server File Share'.
This lets you specify a path for a report file to be written to - you will need to ensure that the Reporting Services server has write access to the destination.
