FTP Error (Different Address Return In PASV Command)
Apr 18, 2012
I was getting this error "The server returned an address in response to the PASV command that is different than the address to which the FTP connection was made." when i trying to get the response from my partner ftp server, Google implies me to change my .UsePassive to false, when i do tat, my error turn to "The operation has timed out" on .GetRequestStream() line. I tried to change my time out values to -1, and it doesn't work as well.
System.Net.WebException was unhandled
Message="The operation has timed out"
Source="System"
StackTrace:
[code]....
And the file is only few kb, by right its not suppose to that long of time to stream it And is this possible the problem cause from FTP server setting? I got no experience in setting FTP server setting so i got no idea whether my connection was restricted by the server?

I have a Callback from a socket that get called each time I get a Packet, It then add an IP address to a Listview. Now I got all the IP with the Active Connections, I cannot, From the call back check if the IP is already added to the list so I made a class and a Delegate and used UI.Invoke to call the method and check if Duplacates then add the coordinating information, I went a Step further and did a lookup on host name to pull the computer hostname from the ipaddress, But I do it each time due to getting Multiple of the same IP and I do not want to do it on the thread that the UI.INvokes from due to resolving a Host name will lock the GUI for a full Second, so you can imagine doing this on a network with constant information.
Now what I want is from the Async thread that is receiving all the data to Invoke the UI thread, check if ListviewItem already exist then exit the Dispatched Sub, then from the Async thread again check the Classes return value then if it dose not already exist start the lookup, I have this so far but Im not 100% sure if it is working the right way, Is Invoke Async or Sync even though Im telling another thread to start, if now how can I made My Async thread wait on UI.Invoke to complete 100% so I can check the classes return value?
Async Thread
Code:
MySubPtr = AddressOf MyDispatch.TreeViewItemExist 'Trigger The Event Through Form1 Backed Up Handle!
Try
'Dim DoesTheItemExist As IAsyncResult
'IAsyncResult = MainHandle.BeginInvoke(MySubPtr)

I examined the ftp logs of our server and there is no difference between a successfull transfer and a failed.I also examinid our firewall and no port blocking has occured

I have the following code:
Dim ipAdd As IPAddress = Dns.GetHostEntry(strHostname).AddressList(0)
Dim strIP As String = ipAdd.ToString()
When I convert to String instead of an IPv4 address like 192.168.1.0 or similar I get the IPv6 version: fd80::5dbe:5d89:e51b:d313 address. Is there a way I can return the IPv4 address from IPAddress type?

I know, it's a bit weird asking for a query to tell me my own email address right, I'll explain further...
I'm writing a COM add-in for Outlook 2007. One of the subs generates and sends an email to a particular address and this all works fine.However I have a need to have an option for the sender to be able to include themselves on the recipients list.As more than one person will be running this I cannot just set the sender's email address manually and would prefer to just add a check box on the form to enable this feature.
The only bit I'm stuck on is working out how to find the email address of the person sending the email. I could do it with an AD query against the logged on user but this needs to work for non-domain users also so need another method.

With an excel file opened, i'm trying to:
Select a Range of Non-Contiguous Cells within a Column, then return the address of the last active cell.
Below, is what I have so far: Note the section maked:
' I can't get the next bit to work: '
To make it work, so far :(
1. Create a new Project using VS-2010.
2. By default, the form should be displayed as "Form1.vb".
3. Add a Label (No need to name or set anything).
4. Add two buttons (Again, No need to name or set anything).
5. Double click on the Form...
6. With the form code displayed, Select all, then paste the following.
'Option Strict Off
'Option Explicit On

What value will be returned from below execution with select, insert, update, delete?
Dim L_EXECUTED_NO1 As Integer = command.ExecuteNonQuery()
Dim L_EXECUTED_NO2 As Integer command.ExecuteReader()
Dim L_EXECUTED_NO2 As Integer = command.ExecuteScalar()
For example, I tried "Dim L_EXECUTED_NO1 As Integer = command.ExecuteNonQuery()" with Update SQL statement and that returned "-1". But it returned 1 for Delete SQL statement.
If Query_SQL("EXEC SP_ATT_CLOCK_INOUT_UPDATE '" & L_TODAY_DT & "', '" & L_EMP_ID & "', '" & L_START_TM & "', '" ) = True Then
MsgBox("Successfully saved!", MsgBoxStyle.Information)
End If

I searched around and could not find a solution so I am sorry if I started something that has already been covered. Want I want to do is run a command line code and simply return a boolean of if it was successful or not. Is this possible? Typically when you run something (example net user User Pass) it will return a value "The command Completed Successfully." If I return this value I will have it from there.

I want to add a scheduled task like this: Dim myProc As Process myProc = Process.Start("at", "02:00 /every:T,W,Th,F,Sa c:ackup.bat") When I type that command at a command prompt it returns "Added a new job with ID = x". How do I get this ID in my code, as it's needed if I want to delete the scheduled job? I've tried looking at some of the properties of myProc but haven't found the right one yet. Maybe I need to wait until the process has completed? (If so, how will I know?).

I'm writing a command-line application in .Net. The app itself is fairly simple, but it has to connect synchronously to a web-service, which in turn has to connect to a Oracle database, and those pieces are fond of taking their time.
Is there a straightforward way (without dividing my app exe in two) to continue executing but nonetheless yield execution to the command prompt?
It's Windows, so no "&". Also, I cannot use cmd.exe's "start" cmdlet.

What I would like to do is create a command button that launches an email from outlook attaching the current word document to a set email address. I'm not fussed if the word document is saved or not as it is only the email receipent that needs it, likewise I don't mind if the code instructs the email to send of just opens it ready to be sent.I have read through loads of forums and tried loads of codes but cannot get any to work.

I am experiencing a perplexing error ("Index was outside the bounds of array") that did not surface a few days ago WITH THE CODE UNCHANGED.
I was even able to successfully create an executable file a few days ago. It was therefore a shock to be given this error when testing it today.

I have a function that returns a double. If in the function I decide the value is invalid, is there any way to return "error" instead of a double? Of course I could pass a boolean by reference and set it false and then check for that back in the calling function, but that seems awkward.
