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();

if (EmpCount == 0)
{

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
{

}
catch (Exception 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 ?

How to fill entry with missing when nothing was writte in in xamarin app?

I am doing Import page and if user leave some entry blank and click on import button I want to fill blank entries with Missing. I have tried that like this:
if (liveryEntry.Text == null)
{
liveryEntry.Text = "Missing";
}
if (registrationEntry.Text == null)
{
registrationEntry.Text = "Missing";
}
if (airportEntry == null)
{
airportEntry.Text = "Missing";
}
if (commentEntry == null)
{
commentEntry.Text = "Missing";
}
But sometimes it works and fill it with Missing, sometimes it doesnt work. What is wrong or is there another way to do that?
Here is full code of method:
private async void buttonImport_Clicked(object sender, EventArgs e)
{
var db = new SQLiteConnection(_dbPath);
db.CreateTable<Airplane>();
collectionPlane.IsVisible = false;
collectionAirline.IsVisible = false;
collectionLivery.IsVisible = false;
collectionRegistration.IsVisible = false;
collectionAirport.IsVisible = false;
try
{
if (liveryEntry.Text == null)
{
liveryEntry.Text = "Missing";
}
if (registrationEntry.Text == null)
{
registrationEntry.Text = "Missing";
}
if (airportEntry == null)
{
airportEntry.Text = "Missing";
}
if (commentEntry == null)
{
commentEntry.Text = "Missing";
}
if (planeEntry.Text != null && airlineEntry.Text != null)
{
var url = PhotoPick();
int i = 1;
int same = 0;
string fileName = registrationEntry.Text;
for (int b = 1; b <= GetNumberPhotos(); b++)
{
if (db.Table<Airplane>().FirstOrDefault(d => d.Id == b) != null)
{
var rowData = db.Table<Airplane>().FirstOrDefault(d => d.Id == b);
string match = rowData.Registration;
if (fileName == match)
{
same++;
}
}
}
i = 1 + same;
fileName = registrationEntry.Text + "-" + i;
var thumbUrl = CreateThumbnail(await url, fileName);
var maxPK = db.Table<Airplane>().OrderByDescending(c => c.Id).FirstOrDefault();
Airplane airplane = new Airplane()
{
Id = (maxPK == null ? 1 : maxPK.Id + 1),
SearchId = planeEntry.Text + airlineEntry.Text + liveryEntry.Text + registrationEntry.Text + airportEntry.Text + datePicker.Date.ToString() + commentEntry.Text,
Plane = planeEntry.Text.ToUpper(),
Airline = airlineEntry.Text,
Livery = liveryEntry.Text,
Registration = registrationEntry.Text.ToUpper(),
Airport = airportEntry.Text.ToUpper(),
Date = datePicker.Date,
Comment = commentEntry.Text,
Url = await url,
ThumbnailUrl = thumbUrl
};
db.Insert(airplane);
await DisplayAlert("Saved", planeEntry.Text + " of " + airlineEntry.Text + " is saved.", "OK");
planeEntry.Text = "";
airlineEntry.Text = "";
liveryEntry.Text = "";
registrationEntry.Text = "";
airportEntry.Text = "";
commentEntry.Text = "";
}
else
await DisplayAlert("Fill all needed fields", "You have to fill all fields except livery and comment", "OK");
}
catch
{
await DisplayAlert("Error", "Something went wrong", "Try again");
}
}

It is probably some kind of bug or missunderstanding #Cfun have solved with if ( string.IsNullOrEmpty(liveryEntry.Text)) and it works as expected.

asynchronous datagrid view c#

People would like to ask you for help with the following situation.
I have a monitor where I check if certain machines are online. To make this process I have a script running on the machine feeding the database with the current time. Already on the monitor, I have an asynchronous check in Infinite loop to pick up the last updated time of the bank and update my Data Grid View. However I'm having some locking problems in this loop, someone could help follow my code

Heads up. The method, PostProcessDSD, tests are too generic. Client contacted me complaining that one of his files was not plotting. It was named "SOUTH". The test for "OUT" in the string caused the issue. No errors were thrown. Just a good ol' fashion mystery.
Change all tests to include the "=". ie else if (str.Contains("OUT=")) { ...
