The first problem is that if I leave username and password fields blank, a warning notification should be appeared at the bottom of the modal (saying "Invalid username or password!"). But when I press the login button, nothing happens.

Thanks. No, I save hashed passwords in MySQL table when the user signup.
For example, user's pass is stored as below:
$2y$10$ogozJf4WuHZg.u7sKFeNOO0qCHPRzePHtjSaOlFGqCj9hu/8WEsyW

Thanks. I know that Distict() can render unique list. But I want to find the index of them.

The last part is wrong (pair.index).

Please help me to know how I can use 'IF' statement in SQL CE and C#.
Please give me an example.

I tried to create a list of values:
IWorkbook workbook = spreadsheetControl.Document;
Worksheet worksheet = workbook.Worksheets["Sheet1"];
CellRange range = worksheet.GetUsedRange();
int LastRow = range.BottomRowIndex;
//MessageBox.Show(Convert.ToString(LastRow));

List<int> numbers = new List<int>();

for (int i = 0; i<12; i++)
{
numbers.Add(Convert.ToInt32(worksheet.Cells[i, 0].Value));
}
The last line needs to be converted to integer, but it gives runtime error:
System.InvalidCastException: 'Unable to cast object of type 'DevExpress.Spreadsheet.CellValue' to type 'System.IConvertible'.'

Please guide me by giving a code so I can study and learn.

I want to learn how such an app can be made. Whether I need to use library? What kind of library should be used?
My final goal is to make my own customized app. Actually, I want to monitor a specific .exe application, when it establishes a connection.
