Ip Addresses Of All Hosts In A Network?
May 6, 2009
how we can enumerate or collect the ip addresses of all the hosts in a network. I am using VB.NET 2005. I tried using system.directoryservices but in vain.Would it be viable to find the subnet range and try pinging to every system within this range ? In this case how do we calculate the subnet range ?

Here is my idea so far: I have a bunch of computers connected in a local network. One of them is a MySQL server, one will have a vb.NET program wich will act as a "second server" and the rest will be different clients. What I want to do is that the "second server" will send out some kind of message or network package to some of the clients in the network, and they will execute a code based on what message it is, or what kind of package it is. I'll give you a simple example:

I've created an application that inserts data into an MySQL database, I have used xampp on the local machine to make sure that the database worked with the application and that everything worked correctly
now when editing the connection string so that I can connect to a remote machine on my LAN I keep getting an error saying "Unable to connect to any of the specified MySql Hosts"
I've checked all the credentials in the connection strings I.E username, password, database name and the machine address.[code]...

I am probably beginner to intermediate at coding now, and want to make an application that interacts with a mysql database on my website.The application would be a Windows 7 App (Windows Forms) and i would like to contact the MySQL database and search and insert etc into it.The problem is my MySQL only allows contact from certain IP address (which you can add, but i cannot add "all")I am looking for advice on methods i could use to interact with the Database on my website, from an application which could be used by multiple users anywhere in the world.

I create an application in VB.net which connects to MySQL, deployed it to 10 computers. 8 of them worked perfectly, 2 of them gave me the error:Unable to connect to any of the specified MySQL hosts.What was different with those 2 computers? Is there any setting I need to do on the MySQL server itself? Anything I need to change/update on those two computers?

I'm on my way to MSDN but thought I'd stop by here first because the answers are usually more cogent.I have a test bed that mimmicks my product app. The general architecture is a factory that builds/instantiates a number of objects (device controllers) that are scalable in number based on requirement. Each object has a threaded portion that reads a device. This way, each object can read its own device simultaneously with all the others. To perform the read, the object calls a routine in a Module that houses the device interfaces. Interestingly (and happily), it seems like each thread has its own copy of the Module routine.
The test bed seems to verify what I'm seeing in the app. In the testbed, a 500 mil second delay is substituted for the device call. Even enclosing the test module portion that hosts the delay in a Synclock results in multi-threaded execution of the pseudo device call. I haven't tested for data yet, but this seems to indicate that when the module routine is called from controller object, it too carries it's own copy of the data just like the calling object. As a long time c++ programmer...that don't quite seem right.

I have a .NET 2.0 *.dll that calls My.Computer.Network.Ping(). The *.dll is then run out of an *.exe via AppDomain.CreateDomain() and Invoke(). The problem is that this works just fine under Windows XP but under Windows 7, I get an exception saying that no network connection is available. I tried the Ping() call out of a small console application under Windows 7 and it works just fine.

I am trying to connect to my remote MySql Database within Visual Studio using the compact framework.
I can successfully add a data source and preview the data within the IDE so assume that the connection is ok regarding Connection strings and remote access.
However, when I attempt to access the data using any run time control I get the following error when the table is loaded using the .fill method.
MySql.Data.MySqlClient.MySqlException was unhandled
ErrorCode=-2147467259
Message="Unable to connect to any of the specified MySQL hosts."

I need an elegant way using VB.Net to iterate through a range of IP addresses when the input will come to my app as a string in this format: 192.168.100.8-10 This range would include 3 addresses: 192.168.100.8, 192.168.100.9, 192.168.100.10. I found a solution in C# that uses the IP Address class that I could probably convert to VB but it seemed to be way too much code for what I need to do. I could definitely use a bunch of string parsing functions but I was hoping someone already had a simple way of doing this.

I have a very long list of points I would like to plot on any state in the US. I would prefer to plot each point with just a dot. All I have is an address that includes the street address, city and state and possibly the zip code. Ideally, I would like to place the resuts in a VB Picture box. I understand there is a Google interface but have found in my research the examples to be lacking exactly what I need.

I would like to match multiple network card MAC's with the corresponding IP Addresses to be displayed. Is there a better (or just another) way to enumerate them besides using System.Management or out-and-out WMI?

Im trying to print addresses on an envelope. Problem is i dont know how to set it to landscape programatically. So its not printing on the envelope properly and is running off the edge.
Ive tried forcing it in the printdialog, however my print dialog isnt working right at the minute - so i mention it here incase the two issues are connected. No matter how many copies i say i want i just get the one, and no matter what printer i select in the printdialog - it prints to the default printer.
Id like to set it programatically anyway so that people can just put an envelope in the tray and then press "Print Envelope" and voila, no messing with print settings.
Heres my code:
Private Sub Envelope_PrintPage(ByVal sender As Object, ByVal e As PrintPageEventArgs) Handles PrintDocument2.PrintPage
Dim txt As String = vbNewLine & vbNewLine & vbNewLine & vbNewLine & TitleBox.Text & " " & FirstNameBox.Text & " " & SurnameBox.Text & " " & vbNewLine & _

I have created an application and I need to send emails to different addresses. I want to do this inside my application without automating email software like outlook etc. I have used CDO , and different activex like ostrosoft , chilkat etc .But is the same problem : Emails are sended correctly without error messages but :Some emails are received ( like in yahoo adresses), a lot of emails are marked as spam, and all the emails send to hotmail addresses are lost, not received. To send emails I'm using a regular domain, with smtp server, port, user name and password. And when I send emails from the same configuration on outlook express from the same computer, all the emails are received correctly.

I thought I had already done this in a previous project and also thought it was really easy but I am now struggling with this.All I want to do is get a list of all of the IP addresses that are assigned to the computer running my app. I thought I would use Net.NetworkInterface.GetAllNetworkInterfaces and then there would be a property on each item in that collection that told me the IPs assigned to that network card but it would seem not.
Searched and searched but the only 'solution' seems to be to use GetDnsHostEntry or WMI something similar and I dont like the sound of either of those. Surely if you can get the DNS servers IP address, Dhcp Server's IP address and Gateway IP address from the NetworkInterface instance then you must be able to get the local IP addresses as well?? I'm sure I am missing something obvious..
