sharepoint deploy operation is not valid due to the current state of the object

I was getting this error while deploying solution when I added an event receiver for ItemAdded event for document libraries. It disappears after removing the elements.xml file from event receiver schema.

Email handler SPEmailEventReceiver does not work in multiple server farm setup

I came across this situation after developing an email event receiver on dev with standalone sharepoint 2010 installation which was working perfectly fine, but for some reason it was not being fired at all when deployed to the live server with multiple server sharepoint farm. All other things were absolutely fine with the live server and the document library would receive email using OOTB email receiving settings.

After searching a lot through intenet and scraching my head, I came across this post which explains the reason and solution. Thank you Benjamin

On another note, a web.config modification also needs to be deployed in a different way on multiple server farm setup. The post below explains just that

Xpath if else statement

Now this is something... I would like to never recall again :)

I came across a situation where I had to use if..else like statement in Infopath XPath expression and below post solved that problem beautifully..

Some more magic in X Path can be seen here

But even after that.. I would prefer to stay away from X Path ;-)

Email mime reader

Codeplex has great utility to read and parse mime email messages

http://mimeparser.codeplex.com/

Specified value is not supported for the urlOfFile parameter

This error is misleading, actually we should not use SPFolder.Files collection to retrieve SPFile object the correct way is to use SPWeb.GetFile method.

Email with Embedded (Inline) image in sharepoint

In asp.net we can send an email with inline image as explained in this post
http://stackoverflow.com/questions/18358534/send-inline-image-in-email

But in sharepoint the procedure is slightly different. I have used below post to do the stuff

http://sharepoint-tamizha.blogspot.co.uk/2013/08/send-email-with-embedded-images-in-c.html


And the final code looks like

byte[] imgByte = null;

SPFile file = SPContext.Current.Web.GetFile(ImageUrl);

                                            imgByte = file.OpenBinary();

// Creating Unique ID for adding image referrence

string GUId1 = Guid.NewGuid().ToString();               

// frame the HTML with the img tag and above unique id

string htmlBody = "<html><body><div><img src=\"cid:" + GUId1 + "\"></div></body></html>";

// Create alternateview object with Mime type HTML

AlternateView avHtml = AlternateView.CreateAlternateViewFromString

                    (htmlBody, null, MediaTypeNames.Text.Html);

//Create object for Linked Resource with the Image physical path or Image Stream

MemoryStream stream = new MemoryStream(imgByte);

                LinkedResource pic1 = new LinkedResource(stream, "image/png");

// Provide the previously created Unique ID to associate the Image with the respective img src.

pic1.ContentId = GUId1;

//Add the Linked Resource to the AlternateView

avHtml.LinkedResources.Add(pic1);

string from = SPContext.Current.Web.Site.WebApplication.OutboundMailSenderAddress;

string smtpAddress =SPContext.Current.Web.Site.WebApplication.OutboundMailServiceInstance.Server.Address;

// Assign SMTP address

SmtpClient smtpClient = new SmtpClient();

smtpClient.Host = smtpAddress;

MailMessage mailMessage = new MailMessage(from, toRecipients);

mailMessage.Subject = subject;

// Add the Alternate view with the Mail message

mailMessage.AlternateViews.Add(avHtml);

mailMessage.IsBodyHtml = true;

smtpClient.Send(mailMessage);
