Searching between two datetimepicker in access database

Hope this helps MS Access (JET Red) requires date literals in SQL to be in the form #MM/dd/yyyy#. Your code however inserts the default string representation of a DateTime value using CurrentCulture, without using any delimiters. Because you're directly concatenating String values with DateTime values, which invokes DateTime.ToString() which is CurrentCulture-sensitive. Use parameters to avoid this issue entirely, and to prevent SQL injection. Also, you're using the same dateTimePicker instance for both values - I think you mean to use dateTimePicker1 and dateTimePicker2 - though you should rename them to minDatePicker and maxDatePicker to be clear what their purpose is.
code :
const String sql = @"SELECT ReceiptID,ID,Name,Paid,Due FROM lastpays where [Dateofpayment] >= ? AND [Dateofpayment] < ?";

OleDbCommand cmd = connection.CreateCommand();
cmd.CommandText = sql;

OleDbParameter pFrom = cmd.CreateParameter();
pFrom.OleDbType = OleDbType.Date;
pFrom.Value     = dateTimePicker1.Value.Date;
cmd.Parameters.Add( pFrom );

OleDbParameter pTo = cmd.CreateParameter();
pTo.OleDbType = OleDbType.Date;
pTo.Value     = dateTimePicker2.Value.Date;
cmd.Parameters.Add( pTo );

OleDbDataAdapter da = new OleDbDataAdapter( selectCommand: cmd );

DataTable data = new DataTable();
da.Fill( data );
dataGridView1.DataSource = data;

Data type mismatch when retrieving records from an access database using a DateTimePicker

will be helpful for those in need dtpDOBFrom.Value is a DateTime, which you are trying to paste into a string. Thus, the DateTime is converted into a string, but the format seems to be different from the format that Access expects. You could play with the parameters of DateTime.ToString (and enclose the date in # instead of ', since this is what Access wants), but that would not be the right way to do it.
The right way, which avoids such type cast problems in general (and SQL injection, among other things), is to use parameters:
code :
cmdSearch.CommandText = "SELECT [First Name], [Surname], [Contact Type], [Birthdate] FROM [Contacts] WHERE [Birthdate] >= ? AND [Birthdate] <= ?";
cmdSearch.Parameters.AddWithValue("DOBFrom", dtpDOBFrom.Value);
cmdSearch.Parameters.AddWithValue("DOBTo", dtpDOBTo.Value);

C#: Value property of DateTimePicker not compatible with Date/Time of MS Access database 2013

will be helpful for those in need Try explicitly parsing your Date as a DateTime object instead of passing in a string via the DateTime.Parse() method :
code :
// Parse your date as an actual Date
DateTime date = DateTime.Parse(dateTimePickerBirthAngajat.Value);
// Pass that parameter along to be executed
_logins.Parameters.AddWithValue("@datetime", date);

Datetimepicker value cannot be stored in Access Database

I hope this helps . You must pass a properly formatted string expression for your date value and use the correct Access SQL syntax, and Name is reserved word, thus:
code :
command.CommandText = "insert into BP ([Name],DateTime,Systolic,Diastolic) VALUES('" + txt_Name.Text + "', #" + dateTimePicker1.Value.ToString("yyyy'/'MM'/'dd hh':'mm':'ss") + "# ," + txt_systolic.Text + "," + txt_diastolic.Text + ");";

VB.Net Inserting DateTimePicker to MS Access Database

wish helps you The problem is the name of the column Time. Time is a reserved word in MS-Access. You need to put square brackets around that name
code :
Dim SQL As String = "INSERT INTO Table1(LastName, [Time]) VALUES (@LastName, @Time)"
cmd.Parameters.Add("@LastName", OleDbType.VarWChar, 100).Value = TextBox1.Text
cmd.Parameters.Add("@Time", OleDbType.DateTime).Value =DateTimePicker1.Value

I think the issue was by ths following , The error you are getting is saying that you are trying to compare a date to an integer. You cannot compare two objects of different types.
From the code in your question, this is caused by line:
