Inserting mysql datas between 2 dates using c#

<asp:TextBox ID="txtstartdate" class="form-control" autocomplete="off" CssClass="datepicker1" runat="server"></asp:TextBox>
<asp:TextBox ID="txtenddate" class="form-control" autocomplete="off" CssClass="datepicker2" runat="server"></asp:TextBox>
<asp:TextBox id="txtreason" TextMode="multiline" runat="server" />
<asp:Button ID="submit" CssClass="login" runat="server" Text="Submit" OnClick="Submit_click" />
Using the Submit_click I want to insert data into table between the 2 dates selected on txtstartdate and txtenddate. txtreason should repeat for all the dates on the table.
For example if select dates 07/30/2018 and 08/04/2018 on txtstartdate and txtenddate and enter "hello" as reason for txtreason, I should get all the dates between 07/30/2018 and 08/04/2018 in the ldate column on the data table and hello should be repeated on reason column for 6 times for each individual dates.
The below method works like a charm if you change date format.
protected void Submit_click(object sender, EventArgs e)
{
DateTime startdate = Convert.ToDateTime(txtstartdate.Text);
DateTime enddate = Convert.ToDateTime(txtenddate.Text);
for (DateTime date = startdate; date <= enddate; date = date.AddDays(1))
{
try
{
string MyConString = "SERVER=localhost;DATABASE=mydb;UID=myid;PASSWORD=abc123;";
MySqlConnection connection = new MySqlConnection(MyConString);
string cmdText = "INSERT INTO approved(agentlogin ,leavetype ,date ,time, reason)VALUES ( #login, #type, #date, 'Full day', #reason)";
MySqlCommand cmd = new MySqlCommand(cmdText, connection);
cmd.Parameters.AddWithValue("#login", Label1.Text);
cmd.Parameters.AddWithValue("#type", ddlleavetype.Text);
cmd.Parameters.AddWithValue("#date", date);
cmd.Parameters.AddWithValue("#reason", txtreason.Text);
connection.Open();
int result = cmd.ExecuteNonQuery();
connection.Close();
//lblError.Text = "Data Saved";
}
catch (Exception)
{
Console.Write("not entered");
//lblError.Text = ex.Message;
}
}
}
This is why you should use models, and utilise the proper types rather than keep everything a string.
While not perfect, a step in the right direction would be something like this :
(Keep in mind that i haven't solved every single problem. there is plenty of room for improvement)
public class DateRangeModel
{
public DateTime From {get; set;}
public DateTime To {get; set;}
public IEnumerable<DateTime> DaysInRange {
get{
for(DateTime date = StartDate; date.Date <= EndDate.Date; date = date.AddDays(1))
{
yield date;
}
}
}
public DateRangeModel(string from, string to)
{
From = GetDate(from);
To = GetDate(to);
}
private static DateTime GetDate(string string_date)
{
DateTime dateValue;
if (DateTime.TryParse(string_date, out dateValue))
return dateValue;
else
throw new Exception("Unable to convert '{0}' to a date.", string_date);
}
}
protected void Submit_click(object sender, EventArgs e)
{
DateRangeModel dateRange = new DateRangeModel(txtstartdate.Text, txtenddate.Text);
OleDbConnection scn = new OleDbConnection();
scn.ConnectionString = #"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=/mysource;";
foreach(var dt in dateRange.DaysInRange)
{
OleDbCommand scmd = new OleDbCommand("Insert query", scn);
scmd.CommandType = CommandType.Text;
scmd.Parameters.Clear();
scmd.Parameters.AddWithValue("#date1", dt);
scmd.Parameters.AddWithValue("reason", txtreason);
//etc (finish your insert stmt here).
}
}
Use the below method to change the date format. Hope this helps
protected void Submit_click(object sender, EventArgs e)
{
DateTime startdate = Convert.ToDateTime(txtstartdate.Text);
DateTime enddate = Convert.ToDateTime(txtenddate.Text);
for (DateTime date = startdate; date <= enddate; date = date.AddDays(1))
{
try
{
var shtdate = date.ToShortDateString();
string MyConString = "SERVER=localhost;DATABASE=mydb;UID=myid;PASSWORD=abc123;";
MySqlConnection connection = new MySqlConnection(MyConString);
string cmdText = "INSERT INTO approved(agentlogin ,leavetype ,date ,time, reason)VALUES ( #login, #type, #date, 'Full day', #reason)";
MySqlCommand cmd = new MySqlCommand(cmdText, connection);
cmd.Parameters.AddWithValue("#login", Label1.Text);
cmd.Parameters.AddWithValue("#type", ddlleavetype.Text);
cmd.Parameters.AddWithValue("#date", shtdate);
cmd.Parameters.AddWithValue("#reason", txtreason.Text);
connection.Open();
int result = cmd.ExecuteNonQuery();
connection.Close();
//lblError.Text = "Data Saved";
}

Console.Write("not entered");
//lblError.Text = ex.Message;

Error when does not select data from DDL

I had this message
Input string was not in a correct format
when inserting values into the database. When I checked I have DDL but I did not select value from it so this message appeared, although I make this column in the database to allow NULL value.
protected void BT_submit_Click(object sender, ImageClickEventArgs e)
{
string File = "~/CvFiles/" + FU_CV.FileName;
if (FU_CV.FileBytes.Length > 4194304)
{
modalpopup.Show();
}
else
{
app.AddApplicant(txt_Mname.Text, Convert.ToInt32(DDL_Dept.SelectedValue));
}
}
private void loadDepts()
{
DDL_Dept.DataSource = d.GetAll();
DDL_Dept.Items.Clear();
DDL_Dept.AppendDataBoundItems = true;
DDL_Dept.Items.Insert(0, new ListItem("-All-", "NULL"));
DDL_Dept.DataValueField = "id";
DDL_Dept.DataTextField = "name";
DDL_Dept.DataBind();
}
public bool AddApplicant(string MiddleName, int Dept_ID)
{
SqlCommand cmd = new SqlCommand("SP_Insert_IntoApplicantforuser");
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("#MiddleName", MiddleName);
cmd.Parameters.AddWithValue("#Dept_ID", Dept_ID);
System.Data.SqlClient.SqlParameter paramter1 = cmd.Parameters.Add("#AppID", SqlDbType.Int);
paramter1.Direction = ParameterDirection.Output;
bool rowaffected;
rowaffected = DBHelper.Instance().Insert(cmd);
if (rowaffected == false)
{
AppID = (int)paramter1.Value;
}
return rowaffected;
}
You should check, if DDL_Dept.SelectedValue is a string representation of int. Use int.TryParse method:
if (FU_CV.FileBytes.Length > 4194304)
{
modalpopup.Show();
}
else
{
int dept;
if (int.TryParse(DDL_Dept.SelectedValue, out dept))
app.AddApplicant(txt_Mname.Text, dept);
else
app.AddApplicant(txt_Mname.Text, -1); //or whatever there should be for you
}

How to auto update startDate and EndDate for next execution?

I need some assistance regarding to how to auto update StartDate and EndDate for next execution. At this moment, I manually add the StartDate and EndDate in sql database and if I didn’t change the StartDate and EndDate, my report will be generating using same StartDate and EndDate. Appreciate if you all can give any idea or suggestion about that. Thanks.
static void Main(string[] args)
{
DateTime start = System.DateTime.Now.AddMinutes(1);
Schedule.PeriodicSchedules schedule =
new Schedule.PeriodicSchedules(start,
Schedule.PeriodicSchedules.Frequency.Minutely);
schedule.Elapsed += new System.Timers.ElapsedEventHandler(GenerateReport);
schedule.Enabled = true;
Console.ReadLine();
}
static void GenerateReport(object sender, EventArgs e)
{
if (TypeOfReport == "BillingReport")
{
DateOfExecution = DateTime.Parse(strDOE);
Schedule.PeriodicSchedules s =
new Schedule.PeriodicSchedules(DateOfExecution,
Schedule.PeriodicSchedules.Frequency.Weekly);
crRpt.Load(BillingReport);
ReportLogin(crRpt);
while (ThisReader.Read())
{
//StartDate and EndDate >>next execution?
crRpt.SetParameterValue("#CollectionStartDate", StartDate);
crRpt.SetParameterValue("#CollectionEndDate", EndDate);
crRpt.SetParameterValue("#SpokeCode", SpokeCode);
}
}
if (TypeOfReport == "ImageReport")
{
DateOfExecution = DateTime.Parse(strDOE);
Schedule.PeriodicSchedules s =
new Schedule.PeriodicSchedules(DateOfExecution,
Schedule.PeriodicSchedules.Frequency.Monthly);
crRpt.Load(ImageReport);
ReportLogin(crRpt);
crRpt.SetParameterValue("#CollectionStartDate", StartDate);
crRpt.SetParameterValue("#CollectionEndDate", EndDate);
crRpt.SetParameterValue("#SpokeCode", SpokeCode);
}
}
I manage to do it by call another method to auto update my DateOfExecution. Let me know if someone have another way. :)
static void GenerateReport(object sender, EventArgs e)
{
if (TypeOfReport == "BillingReport")
{
......
DateOfExecution = DateTime.Parse(strDOE);
Schedule.PeriodicSchedules s = new Schedule.PeriodicSchedules(DateOfExecution, Schedule.PeriodicSchedules.Frequency.Minutely);
//weekly
DateTime StartDate = DateOfExecution.AddDays(-7);
DateTime EndDate = DateOfExecution.AddDays(-1);
..........
UpdateWeekly(DateOfExecution, strReportType);
}
}
static void UpdateWeekly(DateTime DateOfExecution, String strReportType)
{
DateOfExecution = DateOfExecution.AddMinutes(2);
SqlConnection thisConnection = new SqlConnection(SQLConnection);
thisConnection.Open();
SqlCommand thisCommand = thisConnection.CreateCommand();
//thisCommand.CommandText = "INSERT INTO dbo.Schedules (DateOfExecution)" + "Values('"+DateOfExecution+"')";
thisCommand.CommandText = "UPDATE dbo.Schedule set DateOfExecution = '" + DateOfExecution + "' WHERE TypeOfReport = '" + strReportType + "'";
thisCommand.ExecuteNonQuery();
}
