View 1 Replieshow 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 ?
View 2 RepliesI'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]...
Unable to connect to any of the specified MySQL hosts. My code is as follows:

I have checked and double checked username, password, database name, and server. I am new to using MySQL etc., but I pulled the information directly from my phpMyAdmin.
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.
View 6 RepliesI 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?

View 2 RepliesI'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 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."

View 2 RepliesI 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.
View 1 RepliesI 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.

View 1 RepliesIm 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.
View 6 RepliesI 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..
I'm trying to parse a list of web addresses in a textbox.The textbox looks something like this:

We have a VB.NET application that is using the TAPI3Lib.dll. At this one site we can multiple addresses for the same Phone extension. For example for extension 149 we are getting Extension 149 - Address # where # is 0 thru 208. Is there a way to just get "Extension 149"? Have downloaded some free utilities and they only show "Extension 149".Below is the same of code:

What I want to do is use one PC to test an application on another on the same 19.2.168.X.X.I would like to make it seem like SOAP requests are coming from a variety of different PCs, just to make the applciations log file easier to read and I have been told that virtual IP Addresses are the way to go. So, how do I defien a range and then use them one by one in VB? (I guss that this is effectively IP header spooging?)
