ASP.net Sending mail using gmail

Posted on by

In order to send mail using a gmail address this can be used:

In Web.config

	<system.net>
		<mailSettings>
			<smtp from="myemail@gmail.com" deliveryMethod="Network">
				<network
					defaultCredentials="true"
					host="smtp.gmail.com"
					port="587"
					enableSsl="true" />
			</smtp>
		</mailSettings>
	</system.net>

And then in the code (in this case C# is used)

SmtpClient smtpClient = new SmtpClient();
smtpClient.UseDefaultCredentials = true; //reads the settings from web.config
smtpClient.Credentials = new System.Net.NetworkCredential("myemail@gmail.com", "mypassword");
//and then send the message
smtpClient.Send(mailMessage);

Or if you don’t wish to save any settings in web.config

string host = "smtp.gmail.com";
int port = 587;
SmtpClient smtpClient = new SmtpClient(host, port);
smtpClient.UseDefaultCredentials = false;
smtpClient.EnableSsl = true;
smtpClient.Credentials = new System.Net.NetworkCredential("myemail@gmail.com", "mypassword");
//and then send the message contained in mailMessage
smtpClient.Send(mailMessage);

C# parsing through Outlook Calendar items

Posted on by

This code sample will simply parse through all Calendar Items and let us do something with them.
Note: Be aware of what is done here, if there are Items in the Calender with infinite reccurrences (no end date) then this will take forever to parse, so make sure something in the loop causes a break at some point.

	//using the Microsoft Outlook 12 Object library (Microsoft.Office.Interop.Outlook)
	using Microsoft.Office.Interop.Outlook
 
	Microsoft.Office.Interop.Outlook.Application oApp = new Microsoft.Office.Interop.Outlook.Application();
	Microsoft.Office.Interop.Outlook.NameSpace mapiNamespace= oApp.GetNamespace("MAPI"); ;
	Microsoft.Office.Interop.Outlook.MAPIFolder CalendarFolder= mapiNamespace.GetDefaultFolder(Microsoft.Office.Interop.Outlook.OlDefaultFolders.olFolderCalendar);
	Microsoft.Office.Interop.Outlook.Items outlookCalendarItems = CalendarFolder.Items;
 
	outlookCalendarItems.Sort("Start");
	//include recurring events (just a "normal" events i.e once per time it occurs)
	//Have to Sort by Start before setting IncludeRecurrences.
	outlookCalendarItems.IncludeRecurrences = true;
	foreach (Outlook.AppointmentItem item in outlookCalendarItems)
	{
		//Do something with the item
	}

C# MVC# create a URI from a Url.Action

Posted on by

Sometimes the need arises to create a URI object instead of just a link. This can be done by using Url.Action.

new Uri(Url.Action("action", "controller", null, Request.Url.Scheme))
 
//definitions 
public Uri(
	string uriString
)
 
public string Action(
	string actionName,
	string controllerName,
	Object routeValues,
	string protocol
)
