Public Function SaveAccntInfo(usr As String)
Dim successful As Boolean
If gridchanged Then 'If changes made in datagridview
Try
Using con9 As New OleDbConnection(AI_Str)
con9.Open()
Using cmd9 As New OleDbCommand("SELECT * FROM [" & usr & "]", con9)
Using adapter As New OleDbDataAdapter(cmd9)
Dim dt As DataTable = DirectCast(AI_DGV.DataSource, DataTable)
Dim updCom As New OleDbCommand("UPDATE [" & usr & "] SET [LogInDate] = ?, etc. . . .")
Dim insCom As New OleDbCommand("INSERT INTO [" & usr & "] ([LogInDate], etc . . .")
Dim delCom As New OleDbCommand("DELETE FROM [" & usr & "] WHERE [LogInDate] = code", con9)
For Each rows As DataGridViewRow In AI_DGV.Rows
For Each cell As DataGridViewCell In rows.Cells
Dim dateval As DateTime
Dim doubleval As Double
If rows.IsNewRow AndAlso newRow = True Then
With insCom
'INSERT add parameters here
If rows.Cells("LogInDate") IsNot Nothing AndAlso rows.Cells("LogInDate").Value IsNot Nothing AndAlso Not String.IsNullOrWhiteSpace(rows.Cells("LogInDate").Value.ToString()) Then
If Date.TryParseExact(rows.Cells("LogInDate").Value.ToString(), formats, System.Globalization.CultureInfo.InvariantCulture, System.Globalization.DateTimeStyles.None, dateval) Then
.Parameters.Add("@[LogInDate]", OleDbType.Date).Value = dateval
