Excel data reading from Stream and save to the database

In my asp.net MVC application, There is an option to upload data from an excel file. For that, I have used this on my controller.
public ActionResult ImportEmpDetails(HttpPostedFileBase excelFile)
{
try
{
if (excelFile.ContentLength == 0 || excelFile == null)
{
ViewBag.Error = "Please select the excel file";
return View("EmpDetails");
}
else
{
if (excelFile.FileName.EndsWith("xls") || excelFile.FileName.EndsWith("xlsx"))
{
string path = Server.MapPath("~/ExcelFile/" + excelFile.FileName);
if (System.IO.File.Exists(path)) System.IO.File.Delete(path);
excelFile.SaveAs(path);
ExcelPath = Server.MapPath("~/ExcelFile/") + path;
Microsoft.Office.Interop.Excel.Application application = new Microsoft.Office.Interop.Excel.Application();
Microsoft.Office.Interop.Excel.Workbook workbook = application.Workbooks.Open(path);
Microsoft.Office.Interop.Excel.Worksheet worksheet = workbook.ActiveSheet;
Microsoft.Office.Interop.Excel.Range range = worksheet.UsedRange;
List<EmpDetailsVM> xcel = new List<EmpDetailsVM>();
for (int i = 2; i <= range.Rows.Count; i++)
{
try
{
EmpDetails emp = new EmpDetails();
int EmpNo = int.Parse(((Microsoft.Office.Interop.Excel.Range)range.Cells[i, 1]).Text);
var EmpId = (from c in db.CreateEmployee where c.EmpNo == EmpNo select c.Id).First();
emp.EmpID = EmpId;
emp.YearOfService = decimal.Parse(((Microsoft.Office.Interop.Excel.Range)range.Cells[i, 2]).Text);
emp.BasicSalary = decimal.Parse(((Microsoft.Office.Interop.Excel.Range)range.Cells[i, 3]).Text);
emp.EmpCatagory = ((Microsoft.Office.Interop.Excel.Range)range.Cells[i, 4]).Text;
emp.EmpGrade = ((Microsoft.Office.Interop.Excel.Range)range.Cells[i, 5]).Text;
int SupervisorId = int.Parse(((Microsoft.Office.Interop.Excel.Range)range.Cells[i, 6]).Text);
var SupId = (from h in db.CreateEmployee where h.EmpNo == SupervisorId select h.Id).First();
emp.SupervisorId = SupId;
EmpDetailsVM data = new EmpDetailsVM();
data.EmpID = emp.EmpID;
data.YearOfService = emp.YearOfService;
data.BasicSalary = emp.BasicSalary;
data.EmpCatagory = emp.EmpCatagory;
data.EmpGrade = emp.EmpGrade;
data.SupervisorId = emp.SupervisorId;
xcel.Add(data);
}
catch (Exception ex)
{
ViewBag.Error = "Error in " + i + " record";
return View("EmpDetails");
}
}
if (xcel != null)
{
try
{
foreach (var item in xcel)
{
int empID = item.EmpID;
decimal yearOfService = item.YearOfService;
decimal basicSalary = item.BasicSalary;
string catagory = item.EmpCatagory;
string grade = item.EmpGrade;
int supId = item.SupervisorId;
var isEmployeeExists = (from e in dbs.EmpDetails where e.EmpID == empID select e.Id).ToList();
int EmpCount = isEmployeeExists.Count();
if (EmpCount == 0)
{
EmpDetails e = new EmpDetails();
e.EmpID = empID;
e.YearOfService = yearOfService;
e.BasicSalary = basicSalary;
e.EmpCatagory = catagory;
e.EmpGrade = grade;
e.SupervisorId = supId;
dbs.EmpDetails.Add(e);
dbs.SaveChanges();
}
else
{
EmpDetails EmpDetails = dbs.EmpDetails.Where(x => x.EmpID == empID).First();
EmpDetails.YearOfService = yearOfService;
EmpDetails.BasicSalary = basicSalary;
EmpDetails.EmpCatagory = catagory;
EmpDetails.EmpGrade = grade;
EmpDetails.SupervisorId = supId;
db.SaveChanges();
}
}
}
catch (Exception ex)
{
ViewBag.Error = "Error " + ex;
}
TempData["msg"] = "success";
return View("EmpDetails", xcel);
}
else
{
}
return View("EmpDetails");
}
else
{
ViewBag.Error = "Selected excel file not supported";
return View("EmpDetails");
}
}
}
catch (Exception ex)
{
string message = string.Format("<b>Message:</b> {0}<br /><br />", "You do not have access to this view");
message += string.Format("<b>StackTrace:</b> {0}<br /><br />", ex.StackTrace.Replace(Environment.NewLine, string.Empty));
message += string.Format("<b>Source:</b> {0}<br /><br />", ex.Source.Replace(Environment.NewLine, string.Empty));
message += string.Format("<b>TargetSite:</b> {0}", ex.TargetSite.ToString().Replace(Environment.NewLine, string.Empty));
ModelState.AddModelError("Id", message);
}
return View("EmpDetails");
}
This is working properly when I debug the code and run from it using VS. When I applied to the live version, can't upload the excel file there is an exception triggering You do not have access to this view
Want to know how to prevent this or how to do same using stream ?

Hello
I am currently attempting to populate a ListView from a database hosted on AWS. As you can imagine It takes a bit of time to load. My issue is my current code is throwing an error. The error thrown is ambiguous and not helpful just states the program has crashed.
In essence what i want to do is quite simple, I basically want to just display a dialog while these methods are loading.
Any advice regarding my code would be excellent.
Edit: I have narrowed the error message down to this area of the code. Prior to attempting to use threads I was able to load this Activity however due to the fact there wasn't a loading message it would appear to the user that the activity had frozen rather than the fact it was loading.
Thanks,
Joe

So i managed to fix the code above to run correctly.
If you have any feedback or comments let me know and i hope someone finds this helpful.
I was using the Async methods completely incorrectly, you are also unable to call a Async method from the oncreate as i'm sure you are aware. Part of my solution was to change all the methods which i had made Async incorrectly back to void (Meaning they were synchronous).
I then created a thread to run the commands and they are now finally running in the correct order :).
Its important to note within the Thread any elements affected by the UI will required them to be run using the main UI thread, this applies to the methods they called as well.
Below is the area of code which i created to fix the issue i had
// Try catch attempt to catch all errors, the error dialog thrown within
//the catch is fairly simple
try
{
//Start loading spinner
var LoadingProgressDialog = ProgressDialog.Show(this, "Loading", "Loading", false);
//Start loading thread, this thread will carry out the functions
// in the order you requested
Thread LoadingThread = new Thread(() =>
{
//Line below only relevant to my code
StartMonday.Text = "Week Commencing On " + TodaysDate.ToLongDateString();
// Call this method first
SetData(TodaysDate);
// call this method second
FindNotesForWeek(TodaysDate, 7);
//Update the UI on the main thread but call third this will close the loading dialog message
RunOnUiThread(() => LoadingProgressDialog.Hide());
// End of thread
});
//Run the thread
LoadingThread.Start();
}
catch (Exception e)
{
var ErrorMessageDialog = ProgressDialog.Show(this, "Loading", e.ToString(), false);
}

How to implement "apply credit" to existing invoices if credits are available for that customer via .Net C# code by using Interop.QBFC13Lib.dll?

I got stuck when trying to implement the "apply credit" functionality of Quickbooks to existing invoices if credit is available for that customer. I am able to do it via Quickbooks Desktop UI but not getting the way to implement it via a .Net integrated app, written in C#. Can any one please guide on this.
Code which I am using to implement "apply credit" to Quickbooks via C# code.
I am getting the error: "QuickBooks found an error when parsing the provided XML text stream." with below code.
public void ApplyCreditsOnPrePayInvoices()

break;
}
}
}
// now save everything
entity.SaveChanges();
Console.WriteLine(symbol + " added to the " + market + " database!");
}
}
);
}
Everything starts fine and I get no exceptions but I'm getting no results and the code gets stuck one the line that I marked and the memory keeps shooting up. I figured the problem was with the above code because maybe I was doing something wrong. I just don't know where to start as this is my first time dealing with plinq/parallel processing and the tutorials don't show anything this complex.

How to make meeting (in calendar) in outlook 2007 using C#?

How to make meeting (in calendar) in outlook 2007 using C# ?
thank's in advance

This code sample from MSDN should get you started:
private void SetRecipientTypeForAppt()
{
Outlook.AppointmentItem appt =
Application.CreateItem(
Outlook.OlItemType.olAppointmentItem)
as Outlook.AppointmentItem;
appt.Subject = "Customer Review";
appt.MeetingStatus = Outlook.OlMeetingStatus.olMeeting;
appt.Location = "36/2021";
appt.Start = DateTime.Parse("10/20/2006 10:00 AM");
appt.End = DateTime.Parse("10/20/2006 11:00 AM");
Outlook.Recipient recipRequired =
appt.Recipients.Add("Ryan Gregg");
recipRequired.Type =
(int)Outlook.OlMeetingRecipientType.olRequired;
Outlook.Recipient recipOptional =
appt.Recipients.Add("Peter Allenspach");
recipOptional.Type =
(int)Outlook.OlMeetingRecipientType.olOptional;
Outlook.Recipient recipConf =
appt.Recipients.Add("Conf Room 36/2021 (14) AV");
recipConf.Type =
(int)Outlook.OlMeetingRecipientType.olResource;
appt.Recipients.ResolveAll();
appt.Display(false);
}
MSDN

Create object of outlook app using:
private Microsoft.Office.Interop.Outlook.Application outlookApp =
new Microsoft.Office.Interop.Outlook.Application();
and replace Application.CreateItem in code provided by Kyle Rozendo, with outlookApp.
Hope this will help.

This is probably a bit of an overkill but, here is a method that handles Adding, Updating, Deleting events. It also uses almost every calendar event function possible (recurrence by various types, attendees, responses etc.). If you're interested, let me know, I can explain more. It should work off the bat, but I could have missed something, typing this really fast
