Sending e-mails with attachments (a different method)

Fri, 30 Jul 2010 00:00:00 GMT

One of the most asked questions on forums is about sending e-mails from an application.

The easiest method from a .Net application is to use the System.Net.Mail namespace as I covered in September 2007.

Another method is to use the mailto protocol using the Process component which I also covered in December 2003.

Outlook automation is also possible but your users will have to reply to a message saying that something is trying to send a message on their behalf (which most users don’t like).

But those methods are not good for in all situations. For example, the first method (System.Net.Mail) is not linked to your Outlook and then the message is not saved into your sent items. Because the RFC document does not support the attach parameter, not every email applications (Outlook once again) can be used to send attachments when using the second method.

Lately, I found a solution that is working great so far. The last problem I solved with it was to add a button to the Crystal Report viewer to easily attach a PDF version of the currently viewed report to a new e-mail.

I just published a very short (not much time returning from vacation).

This time it is about a new method I found to send emails with attachments using Outlook (without any kind of security dialogs).

Visual Studio 2010: A fix for the "cut/copy insufficient memory" issue

Tue, 29 Jun 2010 00:00:00 GMT

Apparently, some developpers are having issues when they are doing cut and copy operations in Visual Studio 2010.

The official error message reads like this:

"Insufficient available memory to meet the expected demands of an operation at this time, possibly due to virtual address space fragmentation. Please try again later."

Scott Guthrie himself blogged about a public patch available for this issue which you can download and apply here if you are running into it. More details on the issue can be found on the Visual Studio team blog here.

Creating Excel Add-in with VB.net or C#

Sun, 27 Jun 2010 00:00:00 GMT

Two weeks ago, I was asked by a user to provide access to some data of one of their database so that they can use it directly from Excel. I first suggested some methods that are already implemented in the application (like extracting the data and use it in a lookup table). But nothing could satisfy him. He has one idea in mind: being able to use a formula to have access to the data (ie: GetData(value1, value2)) much like Bloomberg and many others vendors are providing.

It was time for me to dig into the creation of an add-in which I knew it was possible but I never built. So guess what is my article all about this month?

I have been quiet in the last few weeks. I wasn't hibernating. I was simply over-busy!

But I took some time to write an article on something I really had to do!

Do you know the TextFieldParser?

Sat, 22 May 2010 00:00:00 GMT

When it comes the time to read a delimited text file, everybody has its own little set of functions to handle that. It is sometime a simple task but it can also be tricky when the files contains delimiters and quotes and delimiters between quotes and ... you know what I mean.

Let me introduce you to another method that is built into the Framework to easily find the data without worrying too much about the delimiters, whether the fields are enclosed into quotes, ... Say you simply want to read the fields into a string collection.

This s exactly what the TextFieldParser class is all about. If provides methods and properties for parsing structured text files. This class is hidden into the Microsoft.VisualBasic.FileIO namespace.
