Is there a way to retrieve events (appointments) from all Outlook's shared calendars?

My problem is, I can't access and so iterate Outlook's shared calendars. I've tried several ways but they all take me back to the default calendar (i.e. my account calendar).
I tried to loop in the subfolders, the GetSharedDefaultFolder() method and using different types of objects of the Interop library but I couldn't solve it.
Here are the methods I've tried. To run the program (in particular GetMethod3() and GetMethod5()) you have to set the string "email" with your own email.
using System;
using System.Text;
using Microsoft.Office.Interop.Outlook;
namespace OutlookTest {
class Program {
static void Main(string[] args) {
OutlookSharedCalendar outlookSharedCalendar = new OutlookSharedCalendar();
}
}
public class OutlookSharedCalendar{
Microsoft.Office.Interop.Outlook.Application oApp;
NameSpace oNameSpace = null;
MAPIFolder oMAPIFolder = null;
MAPIFolder objFolder = null;
MAPIFolder objSubFolder = null;
Explorer objExplorer;
AppointmentItem objCalenderItem;
Folders objOutlookFolders;
AddressEntry addrEntry = null;
Items oCalendarItems = null;
string email = "myemail#email.com";
public OutlookSharedCalendar() {
AppStart();
GetMethod1();
AppEnd();
AppStart();
GetMethod2();
AppEnd();
AppStart();
GetMethod3();
AppEnd();
AppStart();
GetMethod4();
AppEnd();
AppStart();
GetMethod5();
AppEnd();
}
public void GetMethod1() {
oMAPIFolder = oApp.Session.GetDefaultFolder(OlDefaultFolders.olFolderCalendar);
oCalendarItems = (Items)oMAPIFolder.Items;
oCalendarItems.IncludeRecurrences = true;
foreach(AppointmentItem item in oCalendarItems) {
if(item.IsRecurring) {
RecurrencePattern oRP = item.GetRecurrencePattern();
DateTime first = new DateTime(2018, 01, 01, item.Start.Hour, item.Start.Minute, 0);
DateTime last = new DateTime(2019, 10, 31);
AppointmentItem recur = null;
for(DateTime cur = first; cur <= last; cur = cur.AddDays(1)) {
recur = oRP.GetOccurrence(cur);
Console.WriteLine(recur.Subject + " - " + cur.ToLongDateString() + " - " + recur.Body);
}
}
else {
Console.WriteLine(item.Subject + " -> " + item.Start.ToLongDateString());
}
}
}
public void GetMethod2() {
int intFolderCtr;
int intSubFolderCtr;
int intAppointmentCtr;
// >> Initialize The Base Objects
objOutlookFolders = oApp.Session.Folders;
// >> Loop Through The PST Files Added n Outlook
for(intFolderCtr = 1; intFolderCtr <= objOutlookFolders.Count; intFolderCtr++) {
objFolder = objOutlookFolders[intFolderCtr];
objExplorer = objFolder.GetExplorer();
// >> Loop Through The Folders In The PST File
for(intSubFolderCtr = 1; intSubFolderCtr <= objExplorer.CurrentFolder.Folders.Count; intSubFolderCtr++) {
objSubFolder = objExplorer.CurrentFolder.Folders[intSubFolderCtr];
// >> Check if Folder Contains Appointment Items
if(objSubFolder.DefaultItemType == OlItemType.olAppointmentItem) {
// >> Loop Through Appointment Items
for(intAppointmentCtr = 1; intAppointmentCtr <= objSubFolder.Items.Count; intAppointmentCtr++) {
// >> Get Teh Calender Item From The Calender Folder
objCalenderItem = objSubFolder.Items[intAppointmentCtr];
// >> Process Appointment Item Accordingly
Console.WriteLine(objCalenderItem.Subject + " - " + objCalenderItem.Start + " - " + objCalenderItem.Body + " - " + objCalenderItem.Location);
}
}
}
}
}
public void GetMethod3() {
DateTime dtFrom = new DateTime(DateTime.Now.Year, 01, 01);
DateTime dtTo = new DateTime(DateTime.Now.Year, 12, 31);
Recipient teamMember = oApp.Session.CreateRecipient(email);
MAPIFolder sharedCalendar = oApp.Session.GetSharedDefaultFolder(teamMember, OlDefaultFolders.olFolderCalendar);
if(sharedCalendar.DefaultMessageClass != "IPM.Appointment" || teamMember.DisplayType != 0) {
return; //Calendar not shared.
}
string restrictCriteria = "[Start]<=\"" + dtTo.ToString("g") + "\"" + " AND [End]>=\"" + dtFrom.ToString("g") + "\"";
Items results = sharedCalendar.Items.Restrict(restrictCriteria);
foreach(AppointmentItem item in results) {
Console.WriteLine(item.Subject + " - " + item.Start + " - " + item.Body + " - " + item.Location);
}
}
public void GetMethod4() {
oMAPIFolder = oApp.Session.GetDefaultFolder(OlDefaultFolders.olFolderCalendar);
DateTime dtEnd = new DateTime(DateTime.Now.Year, 12, 31);
DateTime dtStart = new DateTime(DateTime.Now.Year, 01, 01);
string restrictCriteria = "[Start]<=\"" + dtEnd.ToString("g") + "\"" +

StringBuilder strBuilder = null;

do {
if(item != null) {
if(item is AppointmentItem) {
counter++;

Console.WriteLine(appItem.Subject + " -> " + appItem.Start.ToLongDateString());
strBuilder.AppendLine("#" + counter.ToString() +

}
item = resultItems.GetNext();
}
}
while(item != null);
}
public void GetMethod5() {
addrEntry = oApp.Session.CurrentUser.AddressEntry;
if(addrEntry.Type == "EX") {
Recipient recip = oApp.Session.CreateRecipient(email);
if(recip.Resolve()) {
Folder folder = oApp.Session.GetSharedDefaultFolder(recip, OlDefaultFolders.olFolderCalendar) as Folder;
foreach(AppointmentItem item in folder.Items) {
Console.WriteLine(item.Subject + " - " + item.Start + " - " + item.Body + " - " + item.Location);
}
}
}
}
public void AppStart() {
// >> Start Outlook
oApp = new Microsoft.Office.Interop.Outlook.Application();
}
public void AppEnd() {
// >> Close Application
oApp.Quit();
// >> Release COM Object
System.Runtime.InteropServices.Marshal.ReleaseComObject(oApp);
oApp = null;
}
}
}
I hope I can get advice on the code or if someone knows a viable alternative to Interop. Thank you all in advance.

The NameSpace.GetSharedDefaultFolder method is used to get a Folder object that represents the specified default folder for the specified user. For example, with minor changes:
public void GetMethod3() {
DateTime dtFrom = new DateTime(DateTime.Now.Year, 01, 01);
DateTime dtTo = new DateTime(DateTime.Now.Year, 12, 31);
Recipient teamMember = oApp.Session.CreateRecipient(email);
teamMember.Resolve();
if(teamMember.Resolved)
{
MAPIFolder sharedCalendar = oApp.Session.GetSharedDefaultFolder(teamMember, OlDefaultFolders.olFolderCalendar);
if(sharedCalendar.DefaultMessageClass != "IPM.Appointment" || teamMember.DisplayType != 0) {
return; //Calendar not shared.
}
string restrictCriteria = "[Start]<=\"" + dtTo.ToString("g") + "\"" + " AND [End]>=\"" + dtFrom.ToString("g") + "\"";
Items results = sharedCalendar.Items.Restrict(restrictCriteria);
foreach(AppointmentItem item in results) {
Console.WriteLine(item.Subject + " - " + item.Start + " - " + item.Body + " - " + item.Location);
}
}
}
As you may see the recipient should be resolved against your address book before trying to access a shared calendar. The Recipient.Resolve method attempts to resolve a Recipient object against the Address Book.

The process cannot access the file "XXX.txt" because it is being used by another process

I would like to write to and read from the same text file. However, I faced the issue of "The process cannot access "XXX.txt" because it is being used by another process".
I created two classes, A & B and define two objects for each of the classes in the main form.
Class A will be writing data into the text file while Class B will reading data from the text file at the same time.
I had put Class B in a timer while Class A will start when I click a button.

Make sure to call Close() on the writer to close it before reading. I've seen instances where utilizing a using block with the writer may not close it in time for the reader to be able to read it.

Slow loading of treeview

I am currently having hard time with Treeview loading. My application has a central panel where multiple user controls are loaded. Each one got a treeview of 5 parent nodes (Groups) owning tens of children nodes (Persons) with a total of 50 nodes.
Same function load the treeview (see down here) :
First loop is adding the Groups and the second loop (into the first) adds the Persons.
That function takes about 10 seconds to load 50 nodes. Which is an eternity in my world.
Don't know what to do to enhance this one. Please have a look at this function.

By the way, here is my calling method :
List<TreeNode> _itemsNodes = FonctionsYou.ArbreCommun(userConnecte.uid);
treeview_arbre.ImageList = FonctionsYou.GetImageListTV();
// Display a wait cursor while the TreeNodes are being created.
Cursor.Current = Cursors.WaitCursor;
// Suppress repainting the TreeView until all the objects have been created.
treeview_arbre.BeginUpdate();
foreach (TreeNode node in _itemsNodes)
{
treeview_arbre.Nodes.Add(node);
}
// Reset the cursor to the default for all controls.
Cursor.Current = Cursors.Default;
// Begin repainting the TreeView.
treeview_arbre.EndUpdate();

How can i pass List<string> response as an xml document using c#

I would like to pass an List response as an xml document and want to load it as xml.
Currently i am performing it using this code :
List<string> BugWSResponseList1 = new List<string>();
BugWSResponseList1 = CreateBugs(FilePath_EXPRESS_API_BugAdd_CreateBugs_DataFile, newValue);
XmlDocument xd = new XmlDocument();
//string s = string.Join(",", BugWSResponseList2);
//xd.LoadXml(s);
string s = "<Bugs>" + string.Join(",", BugWSResponseList1) + "</Bugs>";
xd.LoadXml(s);
//Dictionary Creation for Benchmark API
XmlDocument ResponseNode_bugs = null;
ResponseNode_bugs = new DrWatsonCore().LoadXMLDocument(s);
I would like to avoid to convert the List<string> response to string first and then loading it as xml.
Please suggest how can i achieve that.
Please find the detail of my LoadXMLDocument function as follows:
public XmlDocument LoadXMLDocument(string XMLData)
{
XmlDocument doc = new XmlDocument();
try
{
doc.LoadXml(XMLData);
}
catch (Exception ex)
{
Logger.Write("\n\n" + DateTime.Now + " : " + "LoadXMLDocument : SEVERE ERROR : Failed to create XMLDocument from given string : \n\n");
Logger.Write("\n\n" + DateTime.Now + " : " + "Exception : : \n\n" + ex.Message);
Logger.Write("\n\n" + DateTime.Now + " : " + "Given String : : \n\n");
if (DrWatsonHome.doVerboseLogging)
{
Logger.Write(XMLData);
}
else
{
string Response = XMLData;
Logger.Write("\n\n" + DateTime.Now + " : " + "Response Length : " + Response.Length + " characters.");
int ResponseLengthToPrint = DrWatsonHome.VerboseLogging_Length_Chars < Response.Length ? DrWatsonHome.VerboseLogging_Length_Chars : Response.Length;
Logger.Write("\n\n" + DateTime.Now + " : " + "Response : " + Response.Substring(0, ResponseLengthToPrint) + " ...");
}
}
finally
{
}
return doc;
}
Can i achieve it after making some modifications in it.Please suggest.
I am using List now and my function is as follows:
List<XElement> Sairam(string FilePath, string Timestamp)
{
List<XElement> WSResponse = new List<XElement>();
XmlDocument XDoc = new DrWatsonCore().LoadXMLFromFile(FilePath);
XmlNode BugListNode = XDoc.SelectSingleNode("/DrWatson/Bugs");
List<Bug> BugList = new DrWatsonCore().GetBugList(BugListNode);
List<Thread> BugFtecherThreadList = new List<Thread>();
foreach (Bug bug in BugList)
{
bug.FoundInBuild = Timestamp;
string URL = new DrWatsonCore().CreateWXURL(EXPRESS_API_METHOD.bug_add, bug, REST_EndPoint, AppGUID, new WatsonUser(Username_Watson, Password_Watson));
string Response = string.Empty;
object URLobj = (object) URL;
Response = CreateBug(URLobj);
// WSResponse.Add(Response);
}
return WSResponse;
}
I would like to get the WSResponse as the final response of teh program but i am unable to fetch it. Please suggest so how can i get the response of this program from this function.

Adding webpart to filter view by code is not working

I need to add a new page in a new doc library. That works fine. In the page I need to add a webpart to filter list data from a view bases on 3 columns from the view.
