SendMail - Get Blocked By The "Could Not Create CDO.Message" Error
Mar 11, 2009
I'm having a little difficulty sending mail using VB.Net (2003). I'm attempting to use the company mailhost, and the usual System.Mail methods to do the send, but i get blocked by the "Could not create CDO.Message" error. I've been on MSDN, and looked through the various threads on here, and they all point to a problem with the dll.
The trouble is, that this is not a consistent error. Sometimes it works, sometimes it doesn't. It will work on one user's PC profile, but not another's on the same PC. It will send a mail for a particular user, and then 2 mins later fail to send the same mail. I've tried re-registering the dll anyway, and faffing about in the registry as per the MSDN recommendation, but no joy. And because it's so inconsistent it's proving pretty tricky to narrow down the cause.

create a message box that stores my user name, message, and post datetime into the database as messages are sent. Soon came to realise, what if the user changed his name? So I decided to use the user id (icn) to identify the message poster instead. However, my chunk of codes keep giving me the same error. Says that there are no rows in the dataset.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim name As String
Dim icn As String

I'm using the following code to send an email from my vb.net web application.
Public Function SendMail(ByVal strTo As String, ByVal strFrom As String, _
ByVal strSubject As String, ByVal strBody As String) As String
Try
Dim SmtpServer As New SmtpClient()
Dim mail As New MailMessage()
SmtpServer.Credentials = New _
[Code] .....
It works fine when I use my personal live.co.uk email address as the strFrom value, or even a made-up email address. But when I use a different one (contact@mydomain.com), which is perfectly valid and working, I get the following error:
"The SMTP server requires a secure connection or the client was not authenticated. The server response was: SMTP authentication is required."

I have a task that needs to be executed many times in a thread, so as to keep my GUI responsive. Right now I'm using the ThreadPool to accomplish the tasks, and it works perfectly. I get all the data I expect back from the threads, life's good. When those tasks are finished, I then fire off another set of threads to accomplish another set of tasks, in the same fashion. The work method of these threads uses a call to RegistryKey.OpenRemoteBaseKey, which does exactly that, opens a remote registry key. The problem is: if the user running the application does not have permission to open the remote registry the call will throw an IOException, but I expect this behaviour because the user does not have permission to do it. However, the call itself can take FOREVER.
I wrote the application initially to use delegate methods and used the WaitHandle.WaitOne() method on AutoResetEvents in a state object I passed to each delegate. I tried the WaitOne method using a timeout, which worked fine until I realized that even though the WaitOne timed out, the thread was still running. This is a problem because (from what I understand) processes are only given a certain number of ThreadPool threads and, once used, they must be finished in order to be released back to the threadpool. In my work method, I also have a variable that can be signalled when the thread should be stopped, but that (obviously) only works on code that I've written.how can I cancel a thread that's stuck on a .NET method? Is there some sort of garbage collection method I can call if I give it a handle?

How do i check if specific port is blocked by Windows firewall , both in incoming and outgoing connections.
I've seen code samples such as this one:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs)
Dim host As String = "localhost"
Dim port As Integer = 6900
[Code]....
But how can i know if the exception is thrown specifically because of firewall blocking, and not because of other socket errors?

I am making a banking system in Vb.Net but I had a problem with this function. If a user fails to input the pin number for 3 times, it will be block automatically and will need the admins permission in order for that person to activate the account again. I really don't know how to code the blocking of account and asks for admins authorization to unblock the account again. By the way I'm also using MsAccess as my database for my Bank Simulation.

I know it's possible in asp.net to create a custom error page in a web app, by putting the following line in the web.config: <customErrors mode="RemoteOnly" defaultRedirect="frmErrorPage.aspx" />
I have had to do this for my web app, since it is clearly much tidier than letting the program bomb out with it's ugly default error page. My custom error page just has the customer's logo and a brief message saying "Error has occurred. Please return to homepage"The trouble now is that I have no way of knowing what caused the error, when a customer reports it.
Is there a way to make the actual error message appear on this custom error page too?

Im working on an AutoUpdate class for a small application I've been working on, and with Windows 7 and Vista machines I get a permissions error when trying to replace some of the files in the Application folder. The only way to get it work is to run the application as an administrator. Is there a way I can either attempt to automatically run the app as administrator, or a way of replacing the files that won't be blocked by Vista/7's permission gatekeepers?

I need to create a message box that pops up and says "I am looping, do you want me to continue" with a Yes or No option. If user answers "Yes", I need to continue the loop with another message box with the same question. If the user answers "No", stop the loop.
I have tried this over and over and I get it to the point where if I click "NO" the first time, the message box goes away. but if I click "yes" the first time, no matter how many times I click "NO", the message box will not go away.
This is What I have....
Dim intResult As Integer
intResult = MessageBox.Show("I am Looping. Do you want me to continue?", "Loop", MessageBoxButtons.YesNo)

I would like to create an outlook message with a subject and some attachments for the user to send when they are ready. I have the file paths for the attachments.
Basically the user needs to click a button on the application and that open an outlook message window with a predefined message and a few attachments. They should then be able to modify and add the required "To" etc before sending via outlook.
