An evaluator, Chuck, had a request to use aspNetMime from a classic ASP (COM) application.

Normally, aspNetMime is used in .NET application (C#, VB.NET, etc.. winforms, windows services, and ASP.NET applications). However, occasionally a developer will need to use our assemblies (in this example, aspNetMime) from classic COM applications.

To do this, we must first download the aspNetMime.dll from the website (www.advancedintellect.com)

By default, when you run the aspNetMime.msi install file, it will be installed in the GAC (global assembly cache). However, if you want to manually do this (or if you moved the aspNetMime.dll to a new server), you can use the gacutil.exe (provided by VS.NET).

From a command prompt, call:

        gacutil.exe /I aspNetMime.dll

Once aspNetMime is installed in the GAC, it must be exposed for COM (ASP, VBScript, VB4+). To do this, you need to use the regasm.exe tool (also provided by VS.NET).

To do this, again from a command prompt, execute the following command:

        regasm.exe aspNetMime.dll

Regasm.exe will create a COM wrapper around the aspNetMime.dll, and install the required registry entries, so that aspNetMime can be called for COM.

Once that is done, aspNetMime can now be used in a classic ASP page.  Here is an example, that reads in an email file, and displays the subject and body on a page:

<% Option Explicit%>

<%
Dim mime
Dim lic
Dim subject
Dim plainText
Dim htmlText

'Load the license file
 Set lic = Server.CreateObject( "aspNetMime.MimeMessageLicense" )
 lic.LoadLicenseFile  "c:\aspNetMime.xml.lic"  'loads the license in memory
 
'create the MimeMessage object
 Set mime = Server.CreateObject( "aspNetMime.MimeMessage" )

'load the test email
mime.LoadFromFile( "c:\temp\aspTest.eml")

'read the subject
subject = mime.Subject.Value
Response.Write("<BR>Subject: " + subject)

'get the plain text body (if one exists)
if( not mime.TextMimePart is Nothing ) then
 plainText= mime.TextMimePart.DecodedText
 Response.Write("<HR>")
 Response.Write(plainText)
End if

'get the Html body (if one exists)
if( not mime.HtmlMimePart is Nothing ) then
 htmlText = mime.HtmlMimePart.DecodedText
 Response.Write("<HR>")
 Response.Write(htmlText)
End if
%>

** NOTE: ALL OF OUR PRODUCTS RUN ON ALL VERSIONS OF .NET. **

The instructions below are for people using VS2010 and beyond.

                                                        --------------------------

As more and more people are upgrading to VS2010, and beyond, I am getting more of the following emails:

aspNetEmail (or any of our other products) doesn't work in later versions of Visual Studio. I usually get one of the following errors:

"aspNetEmail is not declared, it may be inaccessible due to its protection level."

Or

"The referenced assembly "…" could not be resolved because it has a dependency upon System.Web (or some other internal .NET namespace).  Please remove references to assemblies not in the targeted framework or consider retargeting your project"

Usually these exceptions occur when the developer is building a client side application.

Starting in VS2010, VS tries to be too smart for it's own good.  When you build a client application (console.exe, winform, etc…) VS limits the number of namespaces you need access too, because it thinks you shouldn't need them.

To change this behavior, what you need to do, is change the target framework from a subset of namespaces, to all of them.

To change this, in VS.NET Solution Explorer, Right-Click on  your project, an select Properties.
 
On the Application tab, set the Target Framework to be ".NET Framework XX". By default it is set to ".NET Framework XX Client Profile".  Press Ctrl-S for save, and you are done.

Below are 2 pictures that display changing the target framework.

As always, if anyone has any questions, feel free to contact me.

Thanks!
