That means that the query you are trying to execute is faulty.

Show the query if you need more information about what exactly is wrong.

Syntax -->The grammatical rules and structural patterns governing the ordered use of appropriate words and symbols for issuing commands, writing code, etc., in a particular software application or programming language.

If you do not follow or write properly the above-mentioned grammatical rules and structural patterns, it causes for syntax error.
You did not follow the rules properly to create your "Insert Into Statement" in your previous post. So it occurs an error.

Your codes occur an exception because you can never attach any quatation mark withen your supplid value to store in database. A single quatation is a syntax symbol in SQL. If you attach it manually in your data to store, SQL does not differ between syntax and data value.
But, you can attach a quatation mark withen the data value if you use parameterized SQL query Statement.

Here, your SQL statement is an example of straightforward SQL statement.
But, by a straightforward SQL statement you could not insert any special characters like quotation mark or percentage symbol in your database.

I am taking here an example. Like

CMD.CommandText =
”UPDATE Customers SET CompanyName = ”’ &
txtCompany.Text & ””’ &
”WHERE CustomerID = ”’ & txtID.Text & ””’

Here,
txtCompany.Text = ’B’s Beverages’
and
txtID.Text = ’BSBEV’

If you attempt to execute this statement, SQL Server will reject it because it produces a syntax error.

The single quote is used to delimit literals, and there should be an even number of single quotes in the statement. The compiler determines that there’s an unclosed quotation mark in the statement and doesn’t execute it. If the same statement was written as a parameterized query, such as the following, you could pass the same company name to the statement:

CMD.CommandText = ”UPDATE Customers SET CompanyName = @CompanyName WHERE CustomerID = @ID”

CMD.Parameters.Add(”@CompanyName”, SqlDbType.VarChar, 40).Value = ”B’s Beverages”

CMD.Parameters.Add(”@ID”, SqlDbType.Char, 5).Value = ”BSBEV”

CMD.ExecuteNonQuery

The same is true for other special characters, such as the percentage symbol. It’s possible to escape the special symbols; you can replace the single-quote mark with two consecutive single quotes, but the most elegant method of handling special characters, such as quotation marks, percent signs, and so on, is to use parameterized queries. You just assign a string to the parameter and don’t have to worry about escaping any characters; the Command object will take care of all necessary substitutions.

is it like this:

Private Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd.Click

    If String.IsNullOrWhiteSpace(txtadmin.Text) Or String.IsNullOrWhiteSpace(txtname.Text) Or String.IsNullOrWhiteSpace(txtcourse.Text) Or String.IsNullOrWhiteSpace(txtic.Text) Or String.IsNullOrWhiteSpace(txtgender.Text) Or String.IsNullOrWhiteSpace(txtaddress.Text) Or String.IsNullOrWhiteSpace(txtbirth.Text) Or String.IsNullOrWhiteSpace(txttel.Text) Or String.IsNullOrWhiteSpace(txtemail.Text) Or String.IsNullOrWhiteSpace(txttpye.Text) Then

Ohhh! I am sorry. It was not in mind that you were using an OleDb Connection.
You SQL Statement is wrong.

I do here some modification in your code, it can help you. Use the symbol"@" at the begining of the name, when you are creating a parameter. This is convention and also syntactical.

Private Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd.Click

    If String.IsNullOrWhiteSpace(txtadmin.Text) Or String.IsNullOrWhiteSpace(txtname.Text) Or String.IsNullOrWhiteSpace(txtcourse.Text) Or String.IsNullOrWhiteSpace(txtic.Text) Or String.IsNullOrWhiteSpace(txtgender.Text) Or String.IsNullOrWhiteSpace(txtaddress.Text) Or String.IsNullOrWhiteSpace(txtbirth.Text) Or String.IsNullOrWhiteSpace(txttel.Text) Or String.IsNullOrWhiteSpace(txtemail.Text) Or String.IsNullOrWhiteSpace(txttpye.Text) Then
        MessageBox.Show("Please complete the on the box.", "Authentication Error", MessageBoxButtons.OK, MessageBoxIcon.Error)

Using conn As New System.Data.OleDb.OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\temp\Database1.accdb")

    Dim Result As Integer
    Dim sql As String = "INSERT INTO tbl_info ([AdminNo],UserName, [Course Title], ICNo, Gender, Address, [Data of Birth], TelNo, Email, Type) values (@AdminNo, @UserName, @CourseTitle, @ICNo, @Gender, @Address, @DateofBirth, @TelNo, @Email, @Type)"

    Dim cmd As New System.Data.OleDb.OleDbCommand(sql, conn)


    cmd.Parameters.Add("@AdminNo", OleDbType.VarChar, 5).Value = txtadmin.Text

    cmd.Parameters.Add("@UserName", OleDbType.VarChar, 12).Value = txtname.Text

        Result = cmd.ExecuteNonQuery()
        If Result > 0 Then
            MessageBox.Show("Successfully created.")

            MessageBox.Show("Failure to create.")
        End If

cmd.Parameters.Clear()
cmd.Dispose()
conn.Close()


If result > 0 Then
   MessageBox.Show("Successfully created.")

   MessageBox.Show("Failure to create.")

For future reference, when you post

Dim sql As String = "INSERT INTO tbl_info ([AdminNo],UserName, [Course Title], ICNo, Gender, Address, [Data of Birth], TelNo, Email, Type) values ('" & txtname.Text & "', '" & txtadmin.Text & "', '" & txtcourse.Text & "', '" & txtic.Text & "', '" & txtgender.Text & "', '" & txtaddress.Text & "','" & txtbirth.Text & "', '" & txttel.Text & "', '" & txtemail.Text & "', '" & txttpye.Text & "')"

we have no easy way of determining what the syntax error might be because it could depend on the values of the various textboxes that you are concatenating. If you are going to post the above code you should also post the result of

MsgBox(sql)

so that we can see the actual query string being passed to the database engine.

what is it mean?

error on Result = cmd.ExecuteNonQuery()

cmd.Parameters.Add("@DateofBirth", OleDbType.Date).Value = txtbirth.Text

How do you insert a text value in a Date Field?

Convert the text type to date type.

cmd.Parameters.Add("@DateofBirth", OleDbType.Date).Value = cDate(txtbirth.Text)

It would be more helpfull if you use MaskTextBox control or DateTimePicker Control to input date type value in the place of a TextBox control.

what do mean by date not valid i ready checked the speilling nothing worng..!!

You can do it easily if you take a DateTimePicker Control instead of txtbirth textbox. In property window set its all properties as you desire.
and put the code

cmd.Parameters.Add("@DateofBirth", OleDbType.Date).Value = DateTimePicker1.Value
