Sendkeys method does not support emojis in selenium basic so I am trying to use a workaround. The workaround I tried works in www.google.com but does not work in the second example.
First example- works OK.
Public bot As New Selenium.Chromedriver
Public Sub Test_google_search()
Dim ele As WebElement
Dim myVar As String
bot.Start
bot.Get "https://www.google.com/"
Set ele = bot.FindElementByName("q")
myVar = "test"
Call MySendKeys(myVar, ele, "value")
bot.Quit
End Sub
2.second sub does not work
Public bot As New Selenium.Chromedriver
Public Sub test(ByVal Row As Long)
Dim Textw As String
Dim Message As String
Dim ele As WebElement
Message = "/html/body/div[1]/div/div/div[4]/div/footer/div[1]/div[2]/div/div[2]"
Textw = "this is a test"
bot.FindElementByXPath(Message, timeout:=60000).Click
Set ele = bot.FindElementByXPath(Message, timeout:=60000)
Call MySendKeys(Textw, ele, "value")
End Sub
''SendKeys that allow to send emoji
Public Sub MySendKeys(ByVal myVar As String, ByVal ele As WebElement, ByVal myAttribute As String)
Dim attrScript As String
attrScript = "arguments[0].setAttribute('" & myAttribute & "','" & myVar & "')"
bot.ExecuteScript attrScript, ele
End Sub

How do I find the name of all inactive Windows VPN adapters? I'm working on a VPN app that should list all VPN connections, whether active or inactive. I'm using the NetworkInterface class to list all adapters. It correctly shows the active or inactive Ethernet 2 adapter (used for OpenVPN), and correctly shows the active VPN L2TP connection, but will not list the inactive VPN L2TP adapter name. Are there other (preferably not too obsolete) .Net (or non .Net) classes I could use? I would like to programmaticaly do this, otherwise I could have the option for the user to set the name (I have code to connect, monitor, or disconnect the Windows VPN adapter by name). Any help would be appreciated. Thanks in advance.
Here is the solution I found:
Public Class VPN

For Each strVpn In vpn_names
Dim vpn As New VPN
vpn.name = strVpn
vpn.type = "Windows VPN"
active = False
vpnCheck.ConName = vpn.name
active = vpnCheck.CheckConnection()
If active = True Then
vpn.status = "Active"
Try
conIPstr = GetMyIPstr()
Catch e As Exception
MessageBox.Show("Error: Function GetConnectionList: Error returning IP Address" & vbCrLf & vbCrLf & e.Message)
End Try
vpn.ip = conIPstr
Else
vpn.status = "Not Active"
vpn.ip = "No IP Address"
End If
vpnList.Add(vpn)
Next
Return vpnList
End Function

I made a program that adds text to the system32 host file and I want a way a button can remove the selected one from the listbox and delete it from the host file here is the code to add it...
If TextBox1.Text = "" Then
MsgBox("Please Enter A Valid Website Url")
Else
path = "C:\Windows\System32\drivers\etc\hosts"
sw = New StreamWriter(path, True)
Dim sitetoblock As String = (Environment.NewLine & "127.0.0.1 " & TextBox1.Text) 'has to be www.google.com | NOT: http://www.google.com/
sw.Write(sitetoblock)
sw.Close()
ListBox1.Items.Add(TextBox1.Text)
MsgBox("Site Blocked")
End If
Thanks for your time
You can use this code to add, read and delete from windows hosts file.
Add this class to your project -
WindowsHost Class:
Public Class WindowsHost
Public ReadOnly Location As String
Private FullMap As List(Of HostMap)
Public Sub New()
Location = Environment.SystemDirectory & "\drivers\etc\hosts"
If Not System.IO.File.Exists(Location) Then
Throw New System.IO.FileNotFoundException("Host File Was Not Found", Location)
End If
FullMap = LoadCurrentMap()
End Sub
Public Function Count() As Integer
Return FullMap.Count
End Function
Public Function Item(ByVal index As Integer) As HostMap
Return New HostMap(FullMap.Item(index))
End Function
Public Sub AddHostMap(ByVal NewMap As HostMap)
FullMap = LoadCurrentMap()
FullMap.Add(NewMap)
SaveData()
End Sub
Public Sub DeleteHostMapByDomain(ByVal dom As String)
FullMap = LoadCurrentMap()
Dim Reall As Integer = 0
For i As Integer = 0 To FullMap.Count - 1 Step 1
If FullMap.Item(Reall).domain = dom Then
FullMap.RemoveAt(Reall)
Else
Reall += 1
End If
Next
SaveData()
End Sub
Public Sub DeleteHostMapByIp(ByVal ip As System.Net.IPAddress)
FullMap = LoadCurrentMap()
Dim Reall As Integer = 0
For i As Integer = 0 To FullMap.Count - 1 Step 1
If FullMap.Item(Reall).Ip.Equals(ip) Then
FullMap.RemoveAt(Reall)
Reall += 1
End If
Next
SaveData()
End Sub
Public Sub UpdateData()
FullMap = LoadCurrentMap()
End Sub
Private Function LoadCurrentMap() As List(Of HostMap)
Dim FileStream As New System.IO.StreamReader(Location)
Dim Lines() As String = FileStream.ReadToEnd.Split(New String() {Environment.NewLine}, StringSplitOptions.None)
FileStream.Close()
Dim Lst As New List(Of HostMap)
For Each line As String In Lines
If Not line.Contains("#") Then
Dim LineData() As String = line.Split({" "c}, StringSplitOptions.RemoveEmptyEntries)
If LineData.Length = 2 Then
Try
Dim temp As New HostMap(LineData(1), System.Net.IPAddress.Parse(LineData(0)))
Lst.Add(temp)
Catch ex As Exception
End Try
End If
End If
Next
Return Lst
End Function
Private Sub SaveData()
Dim Data As String = "# Windows Host Generate" & vbNewLine & "# Time: " & Now.ToString
For Each Map As HostMap In FullMap
Data = Data & vbNewLine & Map.ToString
Next
Dim w As New System.IO.StreamWriter(Location)
w.Write(Data)
w.Close()
End Sub
End Class
Public Class HostMap
Public domain As String
Public Ip As System.Net.IPAddress
Public Sub New(ByVal _dom As String, ByVal _ip As System.Net.IPAddress)
domain = _dom
Ip = _ip
End Sub
Public Sub New(ByRef map As HostMap)
domain = map.domain
Ip = map.Ip
End Sub
Public Overrides Function ToString() As String
Return Ip.ToString & " " & domain
End Function
End Class
Now you can use it like this
Dim WindowsHostSession As New WindowsHost()
WindowsHostSession.AddHostMap(New HostMap("SomeSite.com", System.Net.IPAddress.Parse("127.0.0.1"))) 'Add ip domin map to hosts file
WindowsHostSession.Item(2).domain 'Read the second ip domain map from the hosts file
WindowsHostSession.DeleteHostMapByDomain("SomeSite.com") 'Delete all maps with SomeSite.com domain from the hosts file
Thanks to the wonderful teams of people at Stack Overflow, here is the following code that has been created. It works wonderfully, except for an error at the end that I cannot debunk.
Class:
Private m_arrBuffer

m_arrBuffer = Array()

End Sub
Private Sub Class_Terminate()

End Sub

End Property
Public Property Let Delimiter(strDelimiter)

End Property
Public Sub Append(strValue)
ReDim Preserve m_arrBuffer(UBound(m_arrBuffer) + 1)
m_arrBuffer(UBound(m_arrBuffer)) = strValue
End Sub
Public Sub AppendLine(strValue)
Me.Append strValue & vbCrLf
End Sub
Public Sub Compact()
If Not Me.Delimiter = “” Then
strOriginalDelimiter = Me.Delimiter
Me.Delimiter = “”
End If
strTemp = Me.ToString
m_arrBuffer = Array()
Me.Append strTemp
Me.Delimiter = strOriginalDelimiter
End Sub
Public Function ToArray()
ToArray = m_arrBuffer
End Function
Public Function ToString()
ToString = Join(m_arrBuffer, m_strDelimiter)
End Function
Code (credit to #Bond)
Dim sb
Set sb = New StringBuilder ' Guessing here. You haven't shown the class name.
sb.Append "some string"
sb.Append "another string"
sb.Append "a third string"
....
sb.Delimiter = "<br>"
myHtmlFile.Write sb.ToString()
I am recieving an error at myHtmlFile.Write sb.ToString() Run-time error '424': Object required.
I am not sure but I believe this is the final hurdle before I have a working code. Any advice on how to alleviate this error? Thank you.
for your problem i would say the solution would be:
This code does already assume, that the string is finished
Sub CreateAfile
Dim ie As Object, fs as object
Dim sb
Set sb = New StringBuilder ' Guessing here. You haven't shown the class name.
sb.Append "some string"
sb.Append "another string"
sb.Append "a third string"
....
sb.Delimiter = "<br>"
Set fs = CreateObject("Scripting.FileSystemObject")
Set myHtmlFile = fs.CreateTextFile("U:\temp\MyHTMLfile.htm", True)
myHtmlFile.WriteLine(sb.ToString())
myHtmlFile.Close
Set ie = CreateObject("Internetexplorer.Application")
ie.Visible = True
ie.Navigate "U:\temp\MyHTMLfile.htm"
End Sub

Next

I have noticed that my code does not extract links that ends with </a>. Is there anything i can do to modify my code that it would extract links ending with </a>?
Use following code to grab all of links having 'href' attribute from page:
Dim hNodeCol as HTMLNodeCollection = doc.DocumentNode.SelectNodes("//a[#href]")
...if you still need it, ofcourse ;)
Hey all i have this being called:

Dim arduinoWebSite As New WebBrowser
arduinoWebSite.Navigate("http://192.168.9.39:19/?r=" & command)

updated code that works
Public Sub doStuff(ByVal what2Do As String)
Dim command As String = ""
If Trim(lanSent(1)) = "turnOffPC" Then

You use the Thread.Start(Object) overload to pass data to your handler sub.
