SPF compliant .net system.net.mail .mailmessage

osblues — Wed, 11 Jun 2008 17:08:18 +0000

As a follow up to my post SPF compliant CDO message, here is the equivalent (well, not quite, but similar) vb.net version that I use -

Public Sub Send(ByVal strTo As String, ByVal strFrom As String, _
   ByVal strSender As String, ByVal strCC As String, _
   ByVal strBCC As String, ByVal strSubject As String, _
   ByVal strBody As String)

Dim MailObj As New System.Net.Mail.MailMessage(strFrom, _
   strTo, strSubject, strBody)

'SPF Stuff
If Not String.IsNullOrEmpty(strSender) And strSender <> strFrom Then
   MailObj.Headers.Add("return-path", strSender)
   MailObj.Headers.Add("reply-to", strFrom)
   MailObj.Sender = New Net.Mail.MailAddress(strSender)
End If

If Not strCC = String.Empty Then
   For Each cc As String In strCC.Split(";")
      MailObj.CC.Add(cc)
   Next
End If

If Not strBCC = String.Empty Then
   For Each bcc As String In strBCC.Split(";")
      MailObj.Bcc.Add(bcc)
   Next
End If

Dim MailClient As New System.Net.Mail.SmtpClient
MailClient.Host = "mailserver"
MailClient.Send(MailObj)

End Sub

Again, as before, this is generally useful for web generated emails (like send a friend forms etc.), simply specify the users address as strFrom and a generic local address (noreply@mydomain.com) as strSender.

I hope it proves useful.

Visual Studio 2005 + Vista = Annoying

osblues — Thu, 07 Jun 2007 11:28:24 +0000

I’ve recently upgraded to vista on my laptop at work and am getting increasingly annoyed by one ‘broken’ aspect. Why can I no longer drag files from an explorer window into a ‘Solution Explorer’ in VS?

I’m assuming it’s something to do with them running as slightly different users as I have to run VS ‘as administrator’, well that’s what MS advises anyway.

I do hope this is fixed soon!

GetAbsoluteURL (.net)

osblues — Thu, 07 Sep 2006 21:54:54 +0000

I needed a way to easily convert a relative URL to an absolute URL for a link within a project I’m currently working on. I imagined I’d have to roll something myself and was starting to think it would have to be pretty complex… then .net suprised me

Public Function GetAbsoluteUrl(ByVal currUrl As String, _
ByVal relUrl As String) As String
Dim baseUrl As New Uri(currUrl)
Dim destUrl As New Uri(baseUrl, relUrl)
Return destUrl.AbsoluteUri
End Function

Now that is nifty

Conditional JavaScript in ASP.Net

osblues — Wed, 09 Nov 2005 23:03:23 +0000

Now this is annoying me, I’m trying to take an existing classic ASP solution and convert it to ASP.Net 2.0 as a learning exercise. The problem is that I’m struggling to convert this -


A Page
<% if intCategoryID < 3 then %>

<% end if %>

So, I want to only include the JavaScript if a condition is met (in this case intCategoryID < 3). How do I achieve this in ASP.Net?? I have looked at an asp:literal tag to achieve this but Visual Web Developer suggests a literal cannot include child tags (the script tag itself). Can I add one programmatically from the codebehind?

I hope I can find a solution to this..

Using firefox with Visual Web Developer

osblues — Wed, 26 Oct 2005 10:41:35 +0000

One of the things that’s been really annoying me as that I’ve been forced to use IE to test pages with the ASP.NET Development Server. This is due to NTLM for authentication to the site. However by following the instructions in the link below, firefox now works (the comma separated list of servers just needs to be localhost, although I did add my machine name too)
Firefox and Sharepoint

Learning ASP.Net 2.0

osblues — Wed, 26 Oct 2005 08:35:23 +0000

I’m currently trying to learn ASP.Net 2.0 using the new Visual Web Developer Express IDE. This is kind of different for me as I’ve been a classic ASP developer for many a year now and have always use a text editor for all my development. I’m guessing the best way to approach this is to take an existing ASP solution which I have previously written and try to rewrite it in .Net which is of course a completely different way of thinking. If anyone has any suggestions of good books/sites or anything I should be using then let me know.
