I've got a block of code which sums up time togged for various tasks in a project and returns the total hours logged per project (intMinutesLogged). How do I get my results n descending order?
static async void NotifyEntriesByWorkSpace(Dictionary<string, List<TimeEntry>> dicEntriesByWorkspace, string strChatURL)
{
string strMessage = "";
foreach (var kvpEntry in dicEntriesByWorkspace)
{
var lstTimeEntries = kvpEntry.Value;
string strTitle = "";
var intMinutesLogged = 0;
var intMinutesBillable = 0;
var intMinutesNonBillable = 0;
foreach (var objTimeEntry in lstTimeEntries)
{
if (objTimeEntry.Billable)
{
intMinutesBillable += objTimeEntry.TimeInMinutes;
}
else
{
intMinutesNonBillable += objTimeEntry.TimeInMinutes;
}
}
strTitle = Workspaces.getWorkspaceFromCache(kvpEntry.Key).Title;
//Console.WriteLine(intMinutesLogged + ": " + strTitle + "m");
intMinutesLogged = intMinutesBillable + intMinutesNonBillable;
Console.WriteLine(TimeLoggedMessage(intMinutesLogged) + ": " + strTitle + " " + "(Billable: " + TimeLoggedMessage(intMinutesBillable) + ";" + " " + "Non-Billable: " + TimeLoggedMessage(intMinutesNonBillable) + ")");
strMessage += TimeLoggedMessage(intMinutesLogged) + ": " + strTitle + " " + "(Billable: " + TimeLoggedMessage(intMinutesBillable) + ";" + " " + "Non-Billable: " + TimeLoggedMessage(intMinutesNonBillable) + ")" + "\n";
}
await SendMessage(strChatURL, strMessage);
}
static string TimeLoggedMessage(int intMinutesLogged)
{
return intMinutesLogged / 60 + "h" + " " + intMinutesLogged % 60 + "m";
}
You could use LINQ for this: https://learn.microsoft.com/en-us/dotnet/api/system.linq.enumerable.orderbydescending?view=net-6.0
You could create a simple class or anonymous type to hold the integer values you're summing up (total minutes, billable minutes, non-billable minutes). Then you could populate a collection of this type within the code you shared and afterwards call OrderByDescending on it. You could order based on any of the three integer values.
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;
}
}
This question already has an answer here:
Asp.net losing values of variables
(1 answer)
Closed 4 years ago.
I am running a web Form where I call a new thread on a button press to execute an Rdotnet snippet of code ( I needed the thread because the current thread kept sending stack overload errors ).
In the Rdotnet function , I have it access a global class variable and put data into it. Once the function completes and the button submit function is over I try to access that global class on another button click ( separate button ), however it is empty. I assume that the thread ends so all data in it ends to, so I tried returning the class and putting it into the global variable in the buttonclick function itself,same result.
I need help.

It seems my problem turned out to be unrelated to variable sharing through threads, but instead to deal with the way button click instances worked.
long story short, in order to share a variable between two event instances, the easiest way to do it is through Sessions.
I needed to put the BTlibrary in a session and access it in the second button click event for it to get the value saved from the previous.
protected void Submit_Click(object sender, EventArgs e)
{
Thread current = Thread.CurrentThread;
WebDetails BTlibrary2 =BTlibrary;
Thread t = new Thread(() => { BTlibrary2 = processes(BTlibrary2); }, 2500000);
t.Start();
t.Join();
Session["BTLib"] = BTlibrary2;
// Thread.Sleep(10000);
}
protected void Sendmail(object sender, EventArgs e)
{
List<DirectorDetail> Details = new List<DirectorDetail>();
BTlibrary = (WebDetails) Session["BTLib"];
this worked
I'm building an Edit/Update system in my program using Linq in C# WPF.
My problem is that my code does submit to the LinqToSQLDatacontex but doesn't parse it through to the actual Database.
The result of that is that the datarow is updated in Runtime but in fact isn't updated in the actual Database.
this is the code I use for Updating my rows.

Thanks in advance!!!
I want to prepend headers to my CSV File as to let the data reflect the headings. How would I go about this without having to add it each time writing to the file? Meaning I only want the headers added once on each export. When am exporting to the same file name it should not create duplicates of the same headers. Here is my code below which writes to file:
private void button6_Click_2(object sender, EventArgs e)
{
int count_row = dataGridView1.RowCount;
int count_cell = dataGridView1.Rows[0].Cells.Count;
MessageBox.Show("Please wait while " +comboBox5.Text+ " table is being exported..");
for (int row_index = 0; row_index <= count_row - 2; row_index++)
{
for (int cell_index = 1; cell_index <= count_cell - 1; cell_index++)
{
textBox8.Text = textBox8.Text + dataGridView1.Rows[row_index].Cells[cell_index].Value.ToString() + ",";
}
textBox8.Text = textBox8.Text + "\r\n";
}
System.IO.File.WriteAllText("C:\\Users\\jdavis\\Desktop\\"+comboBox5.Text+".csv", textBox8.Text);
MessageBox.Show("Export of " +comboBox5.Text+ " table is complete!");
textBox8.Clear();
}
Updated attempt:
private void button6_Click_2(object sender, EventArgs e)
{
int count_row = dataGridView1.RowCount;
int count_cell = dataGridView1.Rows[0].Cells.Count;
MessageBox.Show("Please wait while " + comboBox5.Text + " table is being exported..");
if (!File.Exists(comboBox5.Text))
{
string rxHeader = "Code" + "," + "Description" + "," + "NDC" + "," + "Supplier Code"
+ "," + "Supplier Description" + "," + "Pack Size" + "," + "UOM" + Environment.NewLine;
for (int row_index = 0; row_index <= count_row - 2; row_index++)
{
for (int cell_index = 1; cell_index <= count_cell - 1; cell_index++)
{
textBox8.Text = textBox8.Text + dataGridView1.Rows[row_index].Cells[cell_index].Value.ToString() + ",";
}
textBox8.Text = textBox8.Text + "\r\n";
}
System.IO.File.WriteAllText("C:\\Users\\jdavis\\Desktop\\" + comboBox5.Text + ".csv", textBox8.Text);
MessageBox.Show("Export of " + comboBox5.Text + " table is complete!");
textBox8.Clear();
}
}
I really want to try and achieve it without SteamWriter, where am I going wrong?
private void button6_Click_2(object sender, EventArgs e)
{
int count_row = dataGridView1.RowCount;
int count_cell = dataGridView1.Rows[0].Cells.Count;
string path = "C:\\Users\\jdavis\\Desktop\\" + comboBox5.Text + ".csv";
string rxHeader = "Code" + "," + "Description" + "," + "NDC" + "," + "Supplier Code"
+ "," + "Supplier Description" + "," + "Pack Size" + "," + "UOM";
MessageBox.Show("Please wait while " + comboBox5.Text + " table is being exported..");
for (int row_index = 0; row_index <= count_row - 2; row_index++)
{
for (int cell_index = 1; cell_index <= count_cell - 1; cell_index++)
{
textBox8.Text = textBox8.Text + dataGridView1.Rows[row_index].Cells[cell_index].Value.ToString() + ",";
}
textBox8.Text = textBox8.Text + "\r\n";
if (!File.Exists(path))
{
System.IO.File.WriteAllText(path, rxHeader);
System.IO.File.WriteAllText(path, textBox8.Text);
}
else
{
System.IO.File.AppendAllText(path, textBox8.Text);
MessageBox.Show("Export of " + comboBox5.Text + " table is complete!");
textBox8.Clear();
}
}
}
Here is the short version that will even properly handle values that contain , and ":
dataGridView1.ClipboardCopyMode = DataGridViewClipboardCopyMode.EnableAlwaysIncludeHeaderText;
dataGridView1.RowHeadersVisible = false; // the row headers column is copied too if visible
dataGridView1.SelectAll(); // only the selected cells are used (the Windows Clipboard is not used)
DataObject dataObject = dataGridView1.GetClipboardContent(); // 4 Data Formats: Text,Csv,HTML Format,UnicodeText
File.WriteAllText("1.csv", dataObject.GetData("Csv") as string); // DataFormats.CommaSeparatedValue = "Csv"
//string html = Encoding.ASCII.GetString((dataObject.GetData("HTML Format") as MemoryStream).ToArray()); // just the HTML Clipboard Format is in a MemoryStream
This is my suggested solution.
My suggestion is to first check if the file exists or not, to then decide if you need to write the header or not.
private void DoTheWork(int fileIDtoUpdate)
{
//this is just my representation of what probably already exist in your project
string textInTheTextBox = "blah blah blah blah\nI love text\nI love code\nI love to Code\ndon't you just love to code!";
string filePath1 = #"M:\StackOverflowQuestionsAndAnswers\40726017\File1.txt";
string filePath2 = #"M:\StackOverflowQuestionsAndAnswers\40726017\File2.txt";
string filePath3 = #"M:\StackOverflowQuestionsAndAnswers\40726017\File3.txt";
string filePath4 = #"M:\StackOverflowQuestionsAndAnswers\40726017\File4.txt";
string fileToWorkWith = string.Empty;
//decide which file to work with
switch (fileIDtoUpdate)
{
case 1:
fileToWorkWith = filePath1;
break;
case 2:
fileToWorkWith = filePath2;
break;
case 3:
fileToWorkWith = filePath3;
break;
case 4:
fileToWorkWith = filePath4;
break;
default:
break;
}
//check if the file existed
bool fileExisted = File.Exists(fileToWorkWith);
using (StreamWriter sw = new StreamWriter(fileToWorkWith, true))
{
if (!fileExisted)
{
//if the file did not exist, then you need to put your header line!
sw.WriteLine("Write your Header Line here");
}
sw.WriteLine(textInTheTextBox);//down here... who cares if the file existed or not, you need to append this text to it no matter what!
}
}
Got the answer by simply editing my code with this snippet:
if (!File.Exists(path))
{
System.IO.File.WriteAllText(path, rxHeader + textBox8.Text);
}
else
{
System.IO.File.AppendAllText(path, textBox8.Text);
MessageBox.Show("Export of " + comboBox5.Text + " table is complete!");
textBox8.Clear();
}
for (int row_index = 0; row_index <= count_row - 2; row_index++)
{
textBox8.Text = textBox8.Text + "\r\n";
for (int cell_index = 1; cell_index <= count_cell - 1; cell_index++)
{
textBox8.Text = textBox8.Text + dataGridView1.Rows[row_index].Cells[cell_index].Value.ToString() + ",";
}
}
Just go to the property pannel of textBox8. Text and add column header with comma and set the textbox8 visibility to hidden.
