Does anybody know how I can get the URL of any open IE processes on a computer?
I don't need to manipulate the IE instance at all -- just get information about the page that's currently loaded.
Thanks!
This appears to be one way of doing it (code is Visual Basic, sorry, but it shows the principle):
Private Declare Function GETWINDOWTEXT Lib "user32" Alias "GetWindowTextA" (ByVal hwnd As Integer, ByVal lpString As String, ByVal cch As Integer) As Integer
Private Declare Function SetForegroundWindow Lib "user32.dll" (ByVal hwnd As Integer) As Integer
Private Declare Function FindWindowEx Lib "user32" Alias "FindWindowExA" (ByVal hWnd1 As Integer, ByVal hWnd2 As Integer, ByVal lpsz1 As String, ByVal lpsz2 As String) As Integer
Private Declare Ansi Function SendMessage Lib "user32.dll" Alias "SendMessageA" (ByVal hwnd As Integer, ByVal wMsg As Integer, ByVal wParam As Integer, ByVal lParam As String) As Integer
Private Const WM_GETTEXT As Short = &HDS
Private Const WM_GETTEXTLENGTH As Short = &HES
Private Sub Button1_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim hwnd As Integer = FindWindowEx(0, 0, "IEFrame", vbNullString)
If Not hwnd = 0 Then
SetForegroundWindow(hwnd)
Dim Worker As Integer = FindWindowEx(hwnd, 0, "WorkerW", vbNullString)
Dim ToolBar As Integer = FindWindowEx(Worker, 0, "ReBarWindow32", vbNullString)
Dim ComboBoxEx As Integer = FindWindowEx(ToolBar, 0, "ComboBoxEx32", vbNullString)
Dim txtLength As Long = SendMessage(ComboBoxEx, WM_GETTEXTLENGTH, CInt(0), CInt(0)) + 1 ' Get Length Of Text
Dim txtBuff As String = Space(txtLength)
Dim URL As Long = URL = SendMessage(ComboBoxEx, WM_GETTEXT, txtLength, txtBuff) 'Get URL From ComboBoxEx
MsgBox(txtBuff)
End If
End Sub
Basically, you're finding the IE window, then drilling down to find the combobox in which the URL is typed, and then getting whatever string is typed into it. Obviously this isn't a perfect approach (if somebody overwrites the URL but doesn't hit Enter, you wouldn't know it).
A simple solution, and it works:
http://omegacoder.com/?p=63
Start IE yourself through automation (i.e var oIE = WScript.CreateObject("InternetExplorer.Application", "IE_");) and listen to NavigateComplete2.
Peek inot ROT (running objects table) - I think IE documents should show up there - Win32/COM - http://msdn.microsoft.com/en-us/library/ms684004(VS.85).aspx
Just find all IE windows and take text from address well (see MusiGenesis answer for that).

I am using microsoft POS for .net dll and I am converting this part to vb.net from a HOL sample barcode reading tutorial written in c# found here.
EDIT:The device list shows and popup window shows (the activate button is pressed and scanner input is tested)but the txteventhistory is not update even when scanner emulator is used and i suspect the said part is the culprit. thank you for the response
{
Action<string> updateEventHistoryAction = new Action<string>(p => { txtEventHistory.Text = p; });
txtEventHistory.Invoke(updateEventHistoryAction, newEvent);
}
from this
void activeScanner_DataEvent(object sender, DataEventArgs e)
{
UpdateEventHistory("Data Event");
ASCIIEncoding encoder = new ASCIIEncoding();
try
{
// Display the ASCII encoded label text
string data = encoder.GetString(activeScanner.ScanDataLabel);
Action<string> updateScanDataLabelAction = new Action<string>(p => {txtScanDataLabel.Text = p;});
txtScanDataLabel.Invoke(updateScanDataLabelAction, data);
// Display the encoding type
string dataType = activeScanner.ScanDataType.ToString();
Action<string> updateScanDataTypeLabelAction = new Action<string>(p => { txtScanDataType.Text = p; });
txtScanDataType.Invoke(updateScanDataTypeLabelAction, dataType);
// re-enable the data event for subsequent scans
activeScanner.DataEventEnabled = true;
}
catch (PosControlException)
{
// Log any errors
UpdateEventHistory("DataEvent Operation Failed");
}
}
the conversion tool in #develop yielded the one below but i don't think it's correct
Dim updateScanDataLabelAction As New Action(Of String)(function (p)
txtScanDataLabel.Text = p
end function)
txtEventHistory.Invoke(updateEventHistoryAction, newEvent)
I tried converting it to but not quite there i think, though it
Private Sub activeScanner_DataEvent(sender As Object, e As DataEventArgs)
UpdateEventHistory("Data Event")
Dim encoder As New ASCIIEncoding()
Try
' Display the ASCII encoded label text
Dim data As String = encoder.GetString(activeScanner.ScanDataLabel)

I'm using .net web browser control to open an url in new window through proxy with credentials. I use this code for that:
Public Function AppendHeader(ByRef OriginalHeader As String, ByVal Addition As String) As Boolean
If OriginalHeader <> "" Then
OriginalHeader = OriginalHeader + vbNewLine
End If
OriginalHeader = OriginalHeader + Addition
OriginalHeader.Trim(vbNewLine.ToCharArray)
End Function
Public Function Base64Enc(ByRef s As String) As String
Base64Enc = Convert.ToBase64String(System.Text.ASCIIEncoding.ASCII.GetBytes(s))
End Function
Public Sub Navigate()
Dim webBrowser As WebBrowser = New WebBrowser()
Dim headers As String = ""
AppendHeader(headers, "Proxy-Authorization: Basic " & Base64Enc("user:pass"))
'AppendHeader(headers, "Authorization: Basic " & Base64Enc("user:pass"))
webBrowser.Navigate("http://stackoverflow.com", Guid.NewGuid().ToString(), Nothing, headers)
End Sub
This code helps to hide Windows Security window at the first time, but if loading web page sends requests to other urls this window shows again and again (you can see it on a screenshot below).
So what can I do to solve this problem?
(I'm using winforms and vb.net, but C# is suitable too)
Give this a try I am unable to test it :)
Private Sub webBrowser_Navigating(ByVal sender As Object, ByVal e As WebBrowserNavigatingEventArgs)
Dim credentials As New System.Net.NetworkCredential("user", "pwd", "MyDomain")
Dim proxy As New System.Net.WebProxy("127.0.1.2", 80)
If proxy Is Nothing Then
e.Cancel = True

I'm doing a desktop academic project one of the requirment of this project is to allert the user on mobile by sms and this sms should be sent by a mobile that is connected with the pc. I don't know the way how can i do it. When i did google search here i got the gsm modems gateways one kind of solution to send sms through pc. But they are not free. Then Nokia Conectivity SDK is another way but it is not compatible with Visual Studio2010. I got this example on a website but the sender had said at the end there are errors in my code.

but it is in vb.net i have not command in it. is it work?
Kindly Give me some idea, example I'm doing it in winform using c sharp.
hey i used GSMCOMM library and that works for me to send and receive sms using Computer. download it from google and see its examples to check how it works.
here are some links that help
GSMCOMM Send and recieve SMS Using GSM Modem
from here you can download GSMCOMM library
I'm not sure if you want a way to connect to a phone or a way to send an sms from a pc so I'll give both.
To connect to a phone (if it has data and an android or IOS or something where you can directly modify code) you can create a socket connection from your pc to your phone. I have done this in android aps before and it works good.
If you simply need to send an sms from your computer and you know the carrier just send an email using this list http://www.mutube.com/projects/open-email-to-sms/gateway-list/
