Loop troguh appointments in outlook stops at first match

I am using Microsoft.Office.Interop.Outlook and I am trying to loop trough all the appointments that match a particular set of conditions:
To reduce the items I limit the search between two knows maximum dates
It has to contain an "ID"
Beside the additional regex that I don't know if it can be fitted in the .Restrict, the foreach loop interrupts at the first entry
DateTime start = DateTime.Now.AddDays(-1);
string filter1 = "[Start] >= '" + start.ToString("g") + "' AND [End] <= '" + DateTime.MaxValue.ToString("g") + "'";
Outlook.Items calendarItems = personalCalendar.Items.Restrict(filter1);
calendarItems.IncludeRecurrences = true;
calendarItems.Sort("[Start]", Type.Missing);
string filter3 = "#SQL=" + "\"" + "urn:schemas:httpmail:subject" + "\"" + " LIKE '%" + AppCode + "%'";
Outlook.Items restrictedItems = calendarItems.Restrict(filter3);
bool error_free = true;
foreach (Outlook.AppointmentItem apptItem in restrictedItems)
{
MessageBox.Show(apptItem.Subject);
try
{
if (Regex.IsMatch(apptItem.Subject, #"^.*##ManaOrdini\d{1,}##.*$"))
{
apptItem.Move(newCalendarFolder);
}
}
catch (System.Exception ex)
{
MessageBox.Show("Si è verificato un errore durante la creazione dell'appuntamento. Errore: " + ex.Message);
error_free = false;
}
}
Can anybody explain me why? Do I have to add a goto method to iterate untill no entry found?
EDIT
The variable restrictedItems contains the following entries:
Subject "Reminder Ordine Numero:1\t##ManaOrdini1#" System.String
Subject "Reminder Ordine Numero:1\t##ManaOrdini##" System.String
Subject "Reminder Ordine Numero:1\t##ManaOrdini1222##" System.String
Subject "Reminder Ordine Numero:1\t##ManaOrdini1##" System.String
EDIT 2
Ended up with this, basically I had to split in two parts:
Clone the results of the filters
Loop and move
DateTime start = DateTime.Now.AddDays( - 2);
string filter1 = "[Start] >= '" + start.ToString("g") + "' AND [End] <= '" + DateTime.MaxValue.ToString("g") + "'";
Outlook.Items calendarItems = personalCalendar.Items.Restrict(filter1);
calendarItems.IncludeRecurrences = true;
calendarItems.Sort("[Start]", Type.Missing);
string filter3 = "#SQL=" + "\"" + "urn:schemas:httpmail:subject" + "\"" + " LIKE '%" + AppCode + "%'";
Outlook.Items restrictedItems = calendarItems.Restrict(filter3);
bool error_free = true;
int c = 0;
List < Outlook.AppointmentItem > listaApp = new List < Outlook.AppointmentItem > ();
foreach(Outlook.AppointmentItem apptItem in restrictedItems) {
if (Regex.IsMatch(apptItem.Subject, #"^.*##ManaOrdini\d{1,}##.*$")) {
listaApp.Add(apptItem);
c++;
}
}
for (int i = 0; i < c; i++) {
try {
listaApp[i].Move(newCalendarFolder);
}
catch(System.Exception ex) {
MessageBox.Show("Si è verificato un errore durante la creazione dell'appuntamento. Errore: " + ex.Message);
error_free = false;
}
}

How to send an email in Xamarin Android using variables of radio buttons?

Hi I'm doing an applicative and it has an Send E-mail button.
So on that button I want to send some variables that will recieve the value of some RadioGroups.
I did some "If/ElseIf" to allow the user to pick just one RadioGroup and then to send an email (so far so good) to the person that will be in a spinner.
But when I try to choose 2 RadioGroups or more when I click on the "Send E-mail Button" Idk why, the program just pass the value of the last clicked button and don't pass all values that I selected like the following imagesEmail Screen
So how can I send 2 or more variables on the e-mail

Based on your code, I think you tried to use a click event of Button to get checked RadioButton of each RadioGroup, then for example if the layout is like this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RadioGroup
android:id="#+id/group1"
android:layout_height="wrap_content"
android:layout_width="match_parent">
<TextView
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:text="This is group 1" />
<RadioButton
android:id="#+id/radio11"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:text="radio1" />
<RadioButton
android:id="#+id/radio12"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:text="radio2" />
</RadioGroup>
<RadioGroup
android:id="#+id/group2"
android:layout_height="wrap_content"
android:layout_width="match_parent">
<TextView
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:text="This is group 2" />
<RadioButton
android:id="#+id/radio21"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:text="radio3" />
<RadioButton
android:id="#+id/radio22"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:text="radio4" />
</RadioGroup>
<Button
android:id="#+id/checkBtn"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:text="get checked radiobutton" />
</LinearLayout>
You can code like this:
private string result;
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
// Create your application here
SetContentView(Resource.Layout.layout1);
RadioGroup group1 = FindViewById<RadioGroup>(Resource.Id.group1);
RadioGroup group2 = FindViewById<RadioGroup>(Resource.Id.group2);
Button enviar = FindViewById<Button>(Resource.Id.checkBtn);
enviar.Click += (sender, e) =>
{
var itemOfGroup1 = group1.CheckedRadioButtonId;
var itemOfGroup2 = group2.CheckedRadioButtonId;
if (itemOfGroup1 != -1) //if one of the group radio is checked
{
var radiobtn1 = FindViewById<RadioButton>(itemOfGroup1);
result = "group1:" + radiobtn1.Text;
}
if (itemOfGroup2 != -1)
{
var radiobtn2 = FindViewById<RadioButton>(itemOfGroup2);
result = result + " group2:" + radiobtn2.Text;
}
//if there're more groups, codes are the same, for example: result = result + "group3: "+ radiaobtn3.Text;
var email = new Intent(Android.Content.Intent.ActionSend);
email.PutExtra("message", result);
//more email relative codes goes here
};
}
You don't need to have that complex logic, and I only used a simple string to combine all Text of checked RadioButton in the variable value result, you should be able to change the format of this string. Good luck.

Dropdownlist fills multiple times when postback, but I can't put it in !IsPostback

I have a problem I can't figure out. Hope you can help me.
I have an advanced search function, where I first have to choose if I want to search in menus or events by selecting a radiobutton. The problem is, that when I have chosen there is a postback, and I have to fill a dropdownlist with items.
It works fine, but if I search multiple times, the items are filled in again, because it's not in my if(!IsPostback){...} block, but I can't put it there, because there is a postback.
So how do I resolve this? I have tried to clear my items in different places, but that only results in the dropdownlist being empty. Here is some of my code:
if (!IsPostBack)
{
PnlMenu.Visible = false;
PnlEvents.Visible = false;
PnlResult.Visible = false;
//søgemuligheder
RblSearch.Items.Add(new ListItem("MENU", "1"));
RblSearch.Items.Add(new ListItem("EVENTS", "2"));
string _search = Request.QueryString["search"];
DataTable dt = objsearch.Search(_search);
if (!string.IsNullOrEmpty(_search))
{
if (dt.Rows.Count > 0)
{
if (dt.Rows.Count > 1)
{
if (RblSearch.SelectedValue == "1")
{
LitResult.Text += "<h4>Du har søgt på <span style='color: green;'>" + Session["search"].ToString() + "</span> - Der er " + dt.Rows.Count + " menuer, som matcher din søgning:</h4>";
}
if (RblSearch.SelectedValue == "2")
{
LitResult.Text += "<h4>Du har søgt på <span style='color: green;'>" + Session["search"].ToString() + "</span> - Der er " + dt.Rows.Count + " events, som matcher din søgning:</h4>";
}
}
else
{

}

}
}

{

}
}

Async Calls in Xamarins Forms

I'm making an data import to SQLite in Android, using Xamarin Forms C#, and I have problems with this.
To make the data import, i'm using an API, that I developed, and each table has a link, in this case, I'm importing 5 tables, with aproximately 1.000 records each table, I need to make 5 calls (call Table1API, call Table2API, call Table3API, call Table4API, call Table5API)
This is working correctly, but showing this error in DDMS, "I/Choreographer(1273): Skipped 259 frames! The application may be doing too much work on its main thread" and the app crash.
What am I doing wrong?

It seems you are not actually launching a new thread when you click that button. And if so, all that work is being done on the main thread, hence perhaps causing the error. To start a new thread, you do need to call Task.Run(...) or use some other API that will actually start a new thread. As the code is, unless I am missing it, you never start a new thread. You do await some other async operations, i.e. DisplayAlert but because you never use Task.ConfigureAwait(false) you are always being returned to the main thread. IOW if when calling the first async method that you are awaiting, you do the following (in the AsyncTaskTPRE method):
content = await sw.ConsumeRestAPI(pUrl, pAPITKN).ConfigureAwait(false);
when that method returns, you will not be on the UI/Main thread anymore. Without ConfigureAwait(false) when that method returns you are back on the main thread as the default for ConfigureAwait(...) is true.
See MS's guide on using async and await: https://msdn.microsoft.com/en-us/library/mt674882.aspx
In the section titled "Threads" it says the following:
The async and await keywords don't cause additional threads to be created. Async methods don't require multithreading because an async method doesn't run on its own thread. The method runs on the current synchronization context and uses time on the thread only when the method is active. You can use Task.Run to move CPU-bound work to a background thread, but a background thread doesn't help with a process that's just waiting for results to become available.

How get return from callback

I'm using callback to execute a string function, but I can't display the return on a label.
look:
protected void ASPxUploadControl1_FileUploadComplete(object sender,
FileUploadCompleteEventArgs e)
{
try
{
e.CallbackData = SaveNewFile(e.UploadedFile);
lblret.Text = ????
}
catch (Exception ex)
{
String error = ex.ToString();
lbleret.Text = error;
}
}
string SaveNewFile(UploadedFile upfile)
{
if (!upfile.IsValid)
return string.Empty;
String RMSG = "Houve um erro ao enviar o arquivo!";
Guid nid = Guid.NewGuid();
String extOK = "0";
const String updir = "~/tempIMGS/";
String[] extensao = { ".gif", ".png", ".jpeg", ".jpg", ".bmp" };//extensões
FileInfo finfo = new FileInfo(upfile.FileName);
long fmaxsize = 2097152;//tamanho do arquivo
String filext = System.IO.Path.GetExtension(upfile.FileName);
for (int i = 0; i < extensao.Length; i++)
{
if (filext == extensao[i])//se a extensão for permitida
{
if (upfile.ContentLength <= fmaxsize)//se o arquivo tiver no máximo 2mbs
{
extOK = "1";
}
else
{
RMSG = "O arquivo selecionado ultrapassa o tamanho máximo por arquivo (2Mbs) \n " + upfile.FileName.ToString();
}
}
else
{
RMSG = "O arquivo não se encaixa no quadro de extensões permitiras! (.gif , .png , .jpeg , .jpg , .bmp";
}
}
if (extOK == "1")
{
string resFileName = MapPath(updir) + nid + filext;
upfile.SaveAs(resFileName);
//Response.Write("<script>alert('arquivo enviado com sucesso');</script>");
RMSG = "Arquivo enviado com sucesso!";
}
return RMSG;
}
I'm trying execute a function and in the execution define the VAR RMSG with a message, when function ends return the last error message.
see in the 'TRY', e.CallbackData = EXECUTE_FUNCTION; once the return will be stored in e.CallbackData,
How do I get this return from e.callbackdata?

You can store the result first in a variable and then assign it to CallbackData and/or do some transformation with it and assign it to your label like so:
string result = SaveNewFile(e.UploadedFile);
e.CallbackData = result;
lblret.Text = String.Format(
"processed at {0} with a result of: {1}",
DateTime.Now,
result);
