Standard Question #1: What's the error message??
But, I can probably guess at it. You didn't tell the SmtpClient what the resolvable name or IP address of the SMTP Server is that you're going to use to send the email. Yes, you absolutely must have one somewhere to use. No, you probably can't use your own and have it forward to a known SMTP Server on the net. With the proliferation of spam, most SMTP servers are now requiring a login to send mail and wont forward mail from an untrusted SMTP server.

Failure to connect to remote server

I have tried changing host to Dim smtp As New SmtpClient("localhost") but this does nothing.

How do I resolve this? I just want one known machine to email another known machine, it is not for general consumption.

I would tend to use my isp's mail server instead of trying to make my own work.

This tells me that your machine isn't running an SMTP server, or there is no hole in the firewall allowing connections on port 25. Either way, you really can't use a server on your machine because no SMTP server is going to trust your machine and forward its mail. You have to use either your corporate mail server or your ISP's.

Thanks for the pointer, I got hold of them this morning (I was writing app last night in bed!) and have put there smtpclient details in.
Ta Da! It works.
I think it is a PITA that I cannot run localhost.
You were right that Port 25 won't let it in, but speaking to the Tech Guy from our ISP this is because all the arses out there spamming and mass mailing have ruined it for the rest of us! (Which we all knew anyway, but he ranted for about 5 minutes on it anyway!)
Still, nice to get a resolution.

I've got a problem that I can't figure out. I have the below section of code running over and over again (probably 10k-15k times). The variables are as follows:
Wd = a single word passed to the function for checking
SkipList = a list of string patterns to use 'like' with (i.e. "##.#[a-z]") - currently 570 strings.
ct = a counter I just put in to make sure it was running through the whole list (it is).
If SkipList.Contains(Wd) Then
Return Nothing
Else
For Each s As String In SkipList
ct += 1
If Wd.ToLower Like s Then
Return Nothing
Exit Function
End If
Next
End If
The code runs, but at seemingly random intervals it runs slow. I put some code in my function to find out where the overall application was running slow and narrowed it down to this block. The strange thing is that it runs through the whole SkipList in 0 milliseconds most of the time, but here and there it comes up with 15.627 milliseconds. The really strange thing is that it's not in the same place every time. I can use the same function, the same list of words (in the same order), and the same SkipList, and the 15.627ms comes up on different words every time I run it, and it's always exactly 15.627ms.
Can anyone tell me what's going on? Or hints as to what else I can do to speed this up?

Hi,
first of all your observations lack precision. You are relying on the system clock, and that one only advances every 15 milliseconds on your system; if you want to know more about that, read my timers article.
To get more precise measurements, use a better timer (a StopWatch in VB.NET; or a MultiMedia Timer).
Rather than observing say ten times 0 msec, once 15 msec; you will then see say eleven times 1.4 msec
BTW: what is the Exit Function doing in your code?

The code isn't taking exactly 15.627 milliseconds every time it "fails". Unless you're using the high resolution timers, this is the minumum resolution of the timing method you're using.
The problem you have is that you're using 570 different compares against a single word. You need to turn this around and make it so you can do a lookup of the one word on a known list, if at all possible.
Another possibility would be to pre-test the single word to narrow it down to a small number of filters that might apply. If you have a word that starts with a letter, there's no sense in testing a bunch of rules that all start with a number.
But, in the end, it sounds like your code is being stopped by the Garbage Collector while it does it's work. Normally, the GC will stop all threads in your process, walk the object graph looking for things to collect, do it's cleanup work, then resume your threads. Depending on the app, this can take a couple dozen milliseconds, making it look like your code hung for a brief time.
Why is thing happening?? Well, since you're obviously parsing out individual words, you're creating String object after String object, one for each and every word you test. These String objects are dropping out of scope at some point, and the GC has to spend time cleaning them up every once in a while.

I have a small app for a site manager, (so it has to be simple, right?).
I require a Date, Supplier and Load to be sent to another manager.
I have done this as a Form with a DateTimePicker and two ComboBoxes.
Once the selection is made from these boxes, hit the SEND button and the data is to be emailed to the other manager.
I do not want to go through outlook, just email the data.
I have SD1 as Date, SD2 and SD3 as Text.
Is there some way of just sending SD1, SD2 and SD3 to a single fixed address in as few lines of code as possible and without opening outlook?
(I want the site manager to just choose and click).
Thanks

System.Net.Mail namespace has what you're looking for. Documentation[^]

There are other ways but which ever way you choose you will need access to an SMTP server (well at least I think you do!). Do you have a server with IIS installed? Because there is a virtual SMTP server component with IIS.
If you have access to an SMTP server look at System.Net.Mail. Very simple to send emails with very few lines of code.

Hi,anybody knows where i can find a source code to motion detection in Visual Basic 6 for a IP axis cam?

Since VB6 is long since dead, and doesn't do a good job of image processing, I seriously doubt you're going to find any code for this in VB6. It's more likely that you would find components written in other languages, like C++ or C#, that do a much better job of processing images with much better performance.

Unfortunately, the Guest isn't allowed in that part of the registry. There are two alternatives available;
- Use some other account with more privileges than the Guest account
- Store your data in some other place
