How To Return IPv4 Address From IPAddress Type
Jan 12, 2010I 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?

Adding IP Address To ListView - Get Return Value
Nov 5, 2009I 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)

Dec 6, 2009I 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.

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.

IPv4 - IPv6 - UPnP NAT - NAT Traversal Via Teredo
Jan 24, 2010In the past I have written applications that communicate over the network. These have always made use of the System.Net and System.Net.Sockets classes and communicated over TCP connections. The connections have always required an IP address and a port. As these applications have been used by myself and colleages, setting up port forwarding and various other network settings has never been a problem. However, when developing an application for use by the general public, it obviously not a good idea to assume the user is capable of managing these settings.

Networking - Send Messages From One Computer To Another Using .net?
Aug 25, 2011i've been wanting to do this for a few years now and it amazes me that no one can come up with a solution.i want to write a program (preferably in vb.net) that can send a message to another computer (or device) that is connected to the same network as me. I want the message to appear on the other computer (or device) in a popup message box. Also, it would be ideal if this could be done through some sort of bluetooth connection, if not then local ip connection will do. I don't know how i would go about doing this but i know it's possible because i've seen some programs do it... in fact i've seen a program called blackrain that without any additional software installed, can display messages on an ipod touch screen to instruct the yser what to do, and then display the results from their input on the computer screen, almost instantly. I would like to know how that works as well if anyone has any thoughts please feel free to share them!

Dec 4, 2011I am a Network Administrator in the Army so programming is not my strong area. I have been messing with Batch files and WMI, just recently i started VB Scripts (VERY BASIC) like adding an input box to set computer name, scan network for computer name on domain, return wmi info for that remote computer etc... I know there are programs out there that can do all of this, however the Army will only allow certain approved programs to be installed on government workstations, i have been using .Bat files to gather info which is fine, however it is very time consuming when you have entire subnets with computers, networked printers, etc to place into a spreadhseet for higher headquarters tracking not to mention the over 20 columns of required data to track for each computer. I have VB 2010 Express, working on a Windows Form Application Project. Goal is to interface my VB Script (written with notepad) with a GUI that will generate an internal spreadsheet on the form window in a datagridview. So far i have the basic window and i have my gridview with my column headers set. How do i get the data into the columns and rows accordingly.
Application Basic: Execute Program, in main window select button (Scan IP Range) <--- I want this to open an input box for the beginning subnet, input base address to start scan from, next input box for end range, then msgbox for start scan. i want the results of the scan to autofill the datagridview and add new row for each IP address that had a ping reply, returning valid data from WMI results as it receives the data. What would be the best method to achieve my goal. i am not asking you to write the program, i have been looking and studying MULTIPLE sites, think i just need another set of eyes on this to unlock the knowledge i have locked away, if ya know what i mean. Also, if you don't mind let me know what you think of this app im trying to turn out... Super Thanks for your help.This is the Base Batch File running. It calls an external VB Script written in notepad. (I want this implemented into the app form so there is no console window.)This is the inputbox from external VB Script that is called.This the result of the external VB Script (the info i want to put in the datagridview of the app.)I also, for some reason can't get scroll bars to show in the app when i hit F5, theres about 15 columns passed the MAC column...?
Access Database Path On A Networking Computers
Apr 18, 2012Am working a vb.net 2008 project using ms access database 2007 and i successfuly finished it. i published the project and burnt it with cd. my database path in vb.net was located c:Deploydatabase.accdb.
so i installed the program in to another 2 networking PCs. when i run them and put the database path c:Deploydatabase.accdb in every computer, its working. but the problem is that:
i need the database to be accessed by server or my machine for instance where every other networking computers are able to access my database in this location of my machine (my be as defualt) without not putting it to their pcs.
This enables me to see what every machines users can add information to the program.
for example, i have got 10 computers networked each other (i.e comp1, comp2, comp3, comp4, comp5, comp6, comp7, comp8, comp9, comp10). i have installed the program in every computers so when/if comp1 adds/edits informations to the program, then all other computers are capable of receiving this information which means comp4 can see what comp1 has entered in the program.

View 2 RepliesVS 2008 What Approaches Are There For Networking App And Copyprotecting It At Same Time
Dec 7, 2010I have a small application that is currently released. It does not use any database technologies. I built into it some simple copy protection that allows the app to run as a 10 day trial. After this it needs a licence number that I generate based on a code my app provides to the user.This works great for one or two standalone machines but I am now being asked about more flexible pre activated site licencing. Currently this is a bit beyond my skills. I need pointing in the right direction. I assume if I remove my copyprotection and install on a network share, that my app will run.My app also stores some data in the registry which includes the serial number and copy protection data. I could probably switch this to a local file if this helps.What approaches are there for networking my app and copyprotecting it at the same time?

Jun 2, 2011In our VB.Net application, we need to get the path to our data folder in Public Documents. In our standalone application this is straighforward using the SHGetFolderPath function. However, for our network application, we run into a problem when we load the application on a Win 7 server and run it from a Win XP workstation. From the workstations, SHGetFolderPath returns the workstation's public documents folder instead of the what we want, which is the server's public documents path.Is there any way within the application to query the public documents path on the server?
