Appointment in Outlook Express in c# and VB.NET

Something a little more challenging from a Wednesday lunchtime. Here is a little script that you can copy and paste into your page load to create an outlook appointment.

In C# enter the following code :

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;using System.Runtime.InteropServices;using Microsoft.Office.Interop.Outlook;using Outlook = Microsoft.Office.Interop.Outlook;
public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) {
Outlook.ApplicationClass myOutlookApplication = null;
myOutlookApplication = new Outlook.ApplicationClass ();
Outlook.NameSpace myNameSpace = myOutlookApplication.GetNamespace("MAPI");
object myMissing = System.Reflection.Missing.Value ;
myNameSpace.Logon(myMissing, myMissing, myMissing, myMissing);
Outlook.ContactItem myNewContact = (Outlook.ContactItem) myOutlookApplication.CreateItem (Outlook.OlItemType.olContactItem );
myNewContact.FullName = "Helmut Obertanner";System.DateTime myBirthDate = DateTime.Parse ("1.6.1968");myNewContact.Birthday = myBirthDate;myNewContact.CompanyName = "DATALOG Software AG";myNewContact.HomeTelephoneNumber = "49-89-888888888";myNewContact.Email1Address = "someone@datalog.de";myNewContact.JobTitle = "Developer";myNewContact.HomeAddress = "Frundsbergstr. 60\n80637 Munich";
myNewContact.Save();
Marshal.ReleaseComObject (myNewContact);Outlook.AppointmentItem myNewAppointment = (Outlook.AppointmentItem)myOutlookApplication.CreateItem(Outlook.OlItemType.olAppointmentItem);
DateTime myAppointmentDate = DateTime.Now.AddMinutes (2.0);myNewAppointment.Start = myAppointmentDate;
myNewAppointment.Duration = 60;myNewAppointment.Subject = "Meeting to discuss plans...";
myNewAppointment.Body = "Meeting with Helmut to discuss plans.";myNewAppointment.Location = "Home Office";myNewAppointment.ReminderMinutesBeforeStart = 1;myNewAppointment.ReminderSet = true;
myNewAppointment.Save();
Marshal.ReleaseComObject (myNewAppointment);
Outlook.MailItem myNewMail = (Outlook.MailItem)myOutlookApplication.CreateItem(Outlook.OlItemType.olMailItem);
myNewMail.To = "AN EMAIL ADDRESS TO SEND TO";myNewMail.Subject = "About our meeting...";myNewMail.Body = "Hi James,\n\n" + "\tI'll see you in two minutes for our meeting!\n\n" + "Btw: I've added you to my contact list!";
myNewMail.Send();
Marshal.ReleaseComObject (myNewMail);
myNameSpace.Logoff ();Marshal.ReleaseComObject (myNameSpace);Marshal.ReleaseComObject (myOutlookApplication);
}}

And the code in VB.NET is :

Sub calendar_date(ByVal theDate As Date)
Dim objcalendarDate As outlook_appt
objcalendarDate = New outlook_appt
Response.Clear()
Response.ContentType = "text/calendar"
Response.AddHeader("content-disposition", "attachment; filename=outlook_calendar_appointment.vcs")
Response.Write(objcalendarDate.outlookAppt(theDate))
Response.End()
End Sub

str_outlooktime = Format(dat_time, "HHmmss")
End Function

End Function

For the VB.NET code you will need to call the functions from within your page...

Convert string to integer for both C# and VB.NET

Simple one to start, how to convert a string to an integer...

in C# use the following code:

string stringOne;
int integerOne;

stringOne="10";
integerOne = Convert.ToInt32(stringOne);

and in VB.NET :

Dim stringOne as string = nothing
Dim integerOne as integer = nothing

stringOne = "10"
integerOne = Convert.ToInt32(stringOne)

and a little update today to include PHP :

$aString = "10";
$aNumber= (int)$aString ;

Hope this helps someone out there...keep tuned for more coming soon.

Just a quick hello. Being straight to the point, I want to use my blog to display all the need to know scripts and codes in both C# and VB.NET. Hopefully in time I will be able to show the comparisons with PHP and maybe other languages in the future. Keep watching this space. Thank you.
