You can't run a VB.NET program if you don't have the .NET Framework installed on your computer. You can try creating a program in VB 6, that runs in Windows 98 and in XP, but that means you'll have to convert your project to VB 6 (if possible) or to start all over again, or maybe check Google for some other solutions?

You have to install the .NET Framework on any machine that's going to run your application.
There are products out there that will let you get around this, by static-linking your app with the .NET Framework, but they cost BIG $$$$.

We are using a proprietary string buffer protocol via TCP/IP to transfer string buffers back and forth from the server. In this process, we need to be able to reliably overlay structures onto string buffers and vice versa. The structures can have strings, arrays, chars, dates, numbers as their members.
Can someone suggest a reliable way to accomplish this please?

I understand from your things that you transfer the string, so u want to translate a structure into a string.
one way i think about is to convert the structure into bytes and then decode it back.
for each structure you may need some signs, like: 123 mean start to transfer array. 221 mean start one array layer and 122 mean finish transfer the layer. etc.

To send mail, that requires you to set up a SMTP or POP3 server on your computer (a lot more trouble than it's worth). And, this is really hard to do with Windows, so you'd be better off using something like Linux.
And I don't know about sending a fax, but I'm sure it would be pretty advanced.

No, it doesn't! You just need to be able to use a server that's connected to the Internet.

For you, maybe. Not for someone who knows how they work.

First, just saying "Urgent" in a forum will likely just get your post ignored.
Your subject line needs to mention just a little something about the topic, then put the question in the body of the post. Not just "Urgent". No one cares how urgent your need is in a forum environment. If it was that urgent, you'd be doing your own research until the wee hours of the morning, wouldn't you? Since we don't get paid for working on your project, we're sure not going to stay up researching your problem for you!
Now, Ultra was only partiallt correct. You do need an SMTP server to send emails. It does NOT need to be installed on your machine. You just need access to a server that can send the mail for you.
Once you have access to a server, all you need is something liek this:
Imports System.Web.Mail
.
.
.
Dim MyMail As MailMessage = New MailMessage()
MyMail.From = "whoeveryouare@whereeveryouare.com"
MyMail.To = "someone@somewhere.com"
MyMail.Subject = "Subject"
MyMail.Body = "Message body text"
SmtpMail.MailServer = "mail.someserver.com"
SmtpMail.Send(MyMail)
SmtpMail.Send(

Hi,
Does anyone know were I can find some good sample code or tutorials on working with WMI in VB.net in Visual Studio 2005.
Thanks, Andrew Robinson.

I need to create a simple simulation of traffic flowing on a motorway.
How should i go about this?
Any ideas?
Does anybody know any examples?

Well, you could create a animated GIF using Jasc Animation Shop.
Or, to be a little more advanced. You could design a image of a road, then create images of cars. Then have a timer that moves the cars further down the picture of the road every x number of seconds.
I've done something similar using the second method, and it's not too hard, but do it how ever you want.
Hope this helps!

You could check google for some images of vehicles (GIF files support transparent backgrounds), load them in a picturebox in VB (using a transparent background) and then using a timer which moves the car(s) up every second/milisecond. Good luck

I am in the middle of making an application that tweaks the registry like this, (This one just places the admin account on the windows XP startup screen)
Dim reg As RegistryKey
Dim intNumber As Integer = 1
Dim strKey As String = "SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\SpecialAccounts\UserList"
reg = Registry.LocalMachine.CreateSubKey(strKey)
reg.SetValue("Administrator", intNumber)
If Not reg Is Nothing Then reg.Close()
But when you check the box on my application to make this happen, how can i get it so that when the box is unchecked it will reverse the change instead of me manually going into the registry and changing the value back to 0? also how would i make it so that my application will save the checkboxes states when it is closed and then re-opend? 
I really need help with this as microsoft are not much help

You can't, you'd have to store the old value first, and put it in with the same sort of code. There is no 'undo' in the registry.

Then write the states to the registry, or to a config file
SLRGrant wrote: as microsoft are not much help
Well, the first functionality you want does not exist, and the second is widely documented, so I'm not sure where you're having trouble.

What I ment is MS dont seem to explain things properly to people, I myself have browsed the MSDN library and what I have found is not explanatory and I have also googled quite allot and it keeps leading me here so i thought i might aswell ask, I dont normally ask on how to do things but what i mainly need right now is samples of code to guide me through it. All i really know about VB at the moment is how to write values to the registry. Soo, sorry to be a pain but how would I store the 'original' value and then recall it when needed?

SLRGrant wrote: Soo, sorry to be a pain but how would I store the 'original' value and then recall it when needed?
With respect, MSDN assumes a level of prior knowledge, which is fairly basic.
If a registry key contains 0, and you stuff 1 in there, the 0 is lost. So, your best bet is probably to write registry values when the app closes. Otherwise, you need to store the 0 in a local variable, and then set it back to 0 ( or whatever ) from that variable when the box is unchecked. If you don't store it locally, it has been overwritten and is lost.
SLRGrant wrote: All i really know about VB at the moment is how to write values to the registry.
It's highly disfunctional for you to know that, and nothing else. I recommend abandoning this project if this is true, and instead working through a VB.NET book to get some basic skills happening.

Look, I have bought books and have been reading allot off of the internet I am trying to learn this language and as you should know learning a programming lang is just not easy and I am not going to give up so please dont just put me down like this, all I want is some help really and also if you look at the MSDN library quite allot of the articles listed are very low rated by people like me that are trying to learn it because Microsoft just dont explain where or how to insert the code into it, like MS even says "Visual Basic is a program designed for hobbiest and beginners" so please if all you are gong to say is " MSDN assumes a level of prior knowledge, which is fairly basic" please dont reply because MSDN in most places is not 'fairly basic' to most newbie programmers.

SLRGrant wrote: Look, I have bought books and have been reading allot off of the internet
OK - I was taking you at your word. I assume you actually know a lot more than how to save a registry value ?
SLRGrant wrote: also if you look at the MSDN library quite allot of the articles listed are very low rated by people like me that are trying to learn it because Microsoft just dont explain where or how to insert the code into it
They are low rated mostly because a lot of people have unrealistic expectations of how easy it is to program. I blame Microsoft marketing for this.
If you don't know where to put the code, no website can tell you that. Like I said, MSDN expects some knowledge of how to program. It's like an encyclopedia, ( which has lots of info, but if you can't read, it's not much good ). The knowledge is there, you need to know how to use it.
SLRGrant wrote: "Visual Basic is a program designed for hobbiest and beginners"
This is true, the main thing is that VB has English like syntax. It's still programming tho, you still need to be able to learn to program, and that doesn't happen overnight, as you said.
SLRGrant wrote: because MSDN in most places is not 'fairly basic' to most newbie programmers.
I taught myself C++ mostly from MSDN.
Anyhow, I've answered your question, I *am* trying to help. But, based on your comments, 'read a book' was the best help I could offer, as well as the specific answer I gave.
So, have you solved your problem ?

Ok well, im sorry for going a bit nasty then but what mainly gets me in VB is when they present you with a code that looks like this:
Dim valueNames As String() = rk.GetValueNames()
Dim s As String
For Each s In valueNames
Dim rvk As RegistryValueKind = rk.GetValueKind(s)
Select Case rvk
Case RegistryValueKind.MultiString
Dim values As String() = CType(rk.GetValue(s), String())
Console.Write(vbCrLf & " {0} ({1}) =", s, rvk)
For i As Integer = 0 To values.Length - 1
If i <> 0 Then Console.Write(",")
Console.Write(" ""{0}""", values(i))
Next i
Console.WriteLine()
I actually know most of that (after hours of reading a crappy book i paid £40 for) now but when i just started out, I was like W T F is this and wandered where to put it.

the snippet probably should not be used verbatim, it should be read and understood as one example of how the class being documented can be used. The question is, where do you WANT to put it ( that is, where do you want your code to perform the action being documented ) ?

Im sorry you dont understand what I am trying to say, Im trying to say 'if i clicked on a button to make this code run' where would i put this code in the button click event, in the middle, at then end? or maybe this goes at the very start of the program (obviously not in most cases). anyhow this is starting to put me off of coding now since i cant get a straight answer from anyone... I came here to get straight answers like everyone else who posts. not to start a war.

It plain does not matter. Parts of this code, you don't want, they just print to the console. Other parts go where-ever, in the event, you want the registry entry to be written. As I said before, if you want to go back and forth, you're better off writing the values in the close event of the form, and not every time a check box is changed.
SLRGrant wrote: anyhow this is starting to put me off of coding now since i cant get a straight answer from anyone
I am trying desperately to help you, but your questions make no sense to me. I don't know what else you're doing in your event handler, or why you think it matters what order you do things in, but can't work out which order is correct. I don't know if you realise that some of that code isn't about writing to the registry, or if you understand what any of it does, line by line, or just have an idea of what it does as a block.
SLRGrant wrote: I came here to get straight answers like everyone else who posts. not to start a war.
I'm not trying to start any war, I am trying to help. Since the release of the Express Editions, I find often the best help I can give people is to recommend they start over and try to learn some basics. I'm sorry if that offended you, I was only trying to give good advice.

This is driving me crazy! I've been able to relay through my office SMTP server, but I can't use vb.net to authenticate properly through my mailserver at home. I use Kerio Mailserver and my whole family relays through it, but I can't get vb to do it. Here's a sample --
Dim MailClient As New System.Net.Mail.SmtpClient
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.MailClient.Host = "xxxx.xxx"
Me.MailClient.Port = "25"
Dim MyCred As New System.Net.NetworkCredential("Brandon@xxxx.xxxx", "xxxxxxx")
MailClient.UseDefaultCredentials = False
MailClient.Credentials = MyCred
MailClient.Send("Brandon@xxxx.xxx", "bbmxxx@xxxxx.xxx", "[Test]- VB App", "VB App")
End Sub
Now, when I try to send an email to a email address on the mailserver, it works fine. But when trying to send to for example, a Gmail or Yahoo account, it will not - says 'Cannot Relay'. Yes, the user I'm authenticating with does have permission to relay....
Thanks!
Brandon
