We Keep Coding

no argument given that corresponds to required format parameter error

i have ran into some problems with my insert function.
i am trying to make my the string listing_ID an auto increment int with no input needed, however when coding for the button submit i included all the inputs for all the other values but not listing_ID , this gave me the error below. below are all the images and these are the codes for the insert function.

Does anyone know how should fix it in order to get the results i wan? Thank you in advance

As per your screenshot, you are getting compilation error. To Fix it, create another constructor. Currently your code want to invoke constructor which does not take listId as parameter.
public Carlisting(string listID, string car_model, string brand_name, string car_description, string car_condition, string price, string inspection_date)
: this(car_model, brand_name, car_description, car_condition, price, inspection_date)
{
_listID = listID;
}
public Carlisting(string car_model, string brand_name, string car_description, string car_condition, string price, string inspection_date)
{
_car_model = car_model;
_brand_name = brand_name;
_car_description = car_description;
_car_condition = car_condition;
_price = price;
_inspection_date = inspection_date;
}
With above the 1st constructor invokes the another constructor with other required parameters. And for your code, the 2nd constructor will be invoked and you won't have compilation error.

Object reference not set to an instance of an object while Adding Parameter

I want to update some information when a save button is clicked.
I got an error
On : command.Parameters.Add("#doctorID", SqlDbType.Int).Value =
resident.Doctor.DoctorID; Saying: Object reference not set to an

Im guessing I need to create some kind of object?

Looking at the way you've created your Resident:
Resident hello = new Resident();
ucMedicationCheckIn.SaveCheckedInMedication();
ResidentData.Update(hello);
ucMedicationCheckIn.HideDetails();
you probably haven't assigned it a doctor which is why it fails on this line:
command.Parameters.Add("#doctorID", SqlDbType.Int).Value = resident.Doctor.DoctorID;
You need to initialize the Doctor type
Edit*
After seeing your Resident class I can see that you haven't initialized Room either.
You could provide a constructor to initialize these to default values:
public Resident()
{
this.Doctor = new Doctor();
this.Room = new Room();
//etc...
}
Though to do anything meaningful you will probably want to set these up with actual data before saving.

That is because your Doctor and Room are not initialized anyhere:
Resident hello = new Resident();
hello.Doctor = new Doctor();
hello.Room = new Room();
but that update will probably fail as there is no meaningful data in resident and rowsAffected will return 0 probably.

Three-tier architecture implementation in Windows form application

I am trying to insert data into a database using a three-tier architecture, but I am stuck and I cannot proceed further.
This is my code
First is UI part:
public void assignField()
{
string maritalCondition = "";
string sex = "";
assignObj.Registered_Date = dateTimePicker1_Date.Value;
assignObj.First_Name = txt_FirstName.Text;
if (comboBox2_MaritalStatus.SelectedIndex == 0)
{
maritalCondition = "Single";
}
else
maritalCondition = "Married";
assignObj.Marital_Status = maritalCondition;
if (RadioButton_Male.Checked == true)
sex = "Male";
else
sex = "Female";
assignObj.Gender = sex;
this.txt_Age.Text = Convert.ToInt32(age).ToString();
}
private void btnRegister_Click(object sender, EventArgs e)
{
assignField();
}
Next is the middle tier:
public class CustomerDataType
{
private DateTime registered_Date;
private string first_Name;
private int age;
private string marital_Status;
private string gender;
public DateTime Registered_Date
{
get { return registered_Date; }
set { registered_Date = value; }
}
public string First_Name
{
get { return first_Name; }
set { first_Name = value; }
}
public int Age
{
get { return age; }
set { age = value; }
}
public string Marital_Status
{
get { return marital_Status; }
set { marital_Status = value; }
}
public string Gender
{
get { return gender; }
set { gender = value; }
}
public void insertInfo()
{
CustomerDataAccess insertObj = new CustomerDataAccess(Registered_Date, First_Name, Age, Marital_Status, Gender);
insertObj.insertCustomerInfo();
}
}
and last is the data access tier:
public class CustomerDataAccess
{
public CustomerDataAccess(DateTime Registered_Date, string First_Name, int Age, string Marital_Status, string Gender)
{
this.registrationDate = Registered_Date;
this.fName = First_Name;
this.userAge = Age;
this.marriageStatus = Marital_Status;
this.userGender = Gender;
}
SqlConnection con;
SqlCommand cmd;
DateTime registrationDate;
string fName = "";
int userAge;
string marriageStatus;
string userGender;
public void insertCustomerInfo()
{
try
{
con = new SqlConnection("Data Source=LAKHE-PC;Initial Catalog=Sahakari;Integrated Security=True");
con.Open();
cmd = con.CreateCommand();
cmd.CommandText = "sp_registerCust";
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("#Registered_Date", SqlDbType.DateTime);
cmd.Parameters["#Registered_Date"].Value = registrationDate;
cmd.Parameters.Add("#First_Name", SqlDbType.VarChar);
cmd.Parameters["#First_Name"].Value = fName;
cmd.Parameters.Add("#Age", SqlDbType.Int.ToString());
cmd.Parameters["#Age"].Value = userAge;
cmd.Parameters.Add("#Marital_Status", SqlDbType.VarChar);
cmd.Parameters["#Marital_Status"].Value = marriageStatus;
cmd.Parameters.Add("#Gender", SqlDbType.VarChar);
cmd.Parameters["#Gender"].Value = userGender;
cmd.ExecuteNonQuery();
con.Close();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
Here with the stored procedure, there is no problem and and from SQL Server I can insert data into table easily. But from windows form, it does not insert data in table. Plz help me.

I'll do something like below
UI
CustomerHandler custHandler = new CustomerHandler();
// create Customer object and pass to insert method
if (custHandler.InsertCustomer(new Customer(){
FirstName = txt_FirstName.Text, Registered_Date =dateTimePicker1_Date.Value,
//decalare other parameters....
))
{
// insert Success, show message or update label with succcess message
}
In my BL
public class CustomerHandler
{
// in BL you may have to call several DAL methods to perform one Task
// here i have added validation and insert
// in case of validation fail method return false
public bool InsertCustomer(Customer customer)
{
if (CustomerDataAccess.Validate(customer))
{
CustomerDataAccess.insertCustomer(customer);
return true;
}
return false;
}
}
In MY DAL
// this is the class you going to use to transfer data across the layers
public class Customer
{
public DateTime Registered_Date { get; set; }
public string FirstName { get; set; }
//so on...
}
public class CustomerDataAccess
{
public static void insertCustomer(Customer customer)
{
using (var con = new SqlConnection("Data Source=LAKHE-PC;Initial Catalog=Sahakari;Integrated Security=True"))
using (var cmd = con.CreateCommand())
{
con.Open();
cmd.CommandText = "sp_registerCust";
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("#Registered_Date", customer.Registered_Date);
cmd.Parameters.AddWithValue("#FirstName", customer.FirstName);
// so on...
cmd.ExecuteNonQuery();
}
}
internal static bool Validate(Customer customer)
{
// some validations before insert
}
}

Your middle tier consists of classes holding the values you require in properties. Instead of writing the data access manually, try using the Entity Framework (EF) which does that for you.
Here (at MSDN) you can find a quickstart example which shows you how you can use it.
Instead of mapping the fields manually and executing a query, the Entity Framework does that which means you just have to assign the values to the object's properties and call SaveChanges() - the SQL code is created and executed automatically by the EF.
For further reading, there is also a lot to find here (at Stackoverflow).

How to populate BrightIdeasSoftware.TreeListView ?

I just downloaded ObjectListView, and have an issue with populating it.
I got list of MyObject:
public class MyObject
{
public int Id { get; set; }
public int ParentId { get; set; }
public string Name { get; set; }
public int Data { get; set; }
public MyObject(int id, int parentId, string name, int data)
{
Id = id;
ParentId = parentId;
Name = name;
Data = data;
}
}
List<MyObject> list = List<MyObject>();
I need to populate a TreeListView with MyObject elements (Using TreeListView).
Also I need one column been filled with .Data property.
I can not populate it even as a list(all items on the same level) and without any columns, I've tried this:
this.myTreeListView.SetObjects(list);
and this:
this.myTreeListView.Roots = list;
But the tree is still empty, nothing has been populated, what am I doing wrong ? Please help.

You can find some useful "getting started" information regarding the TreeListView here. Make sure you understand and use that concept.
However, there is no mention that you also have to add at least one column (you can do this in the designer). So this might be your problem. The TreeListView tutorial assumes that you already know how to use the ObjectListView.
I suggest you also read the general getting started guide, especially the "mental gear shift" section.
The crucial part of using an ObjectListView is configuring it. Most of this configuration can be done within the IDE by setting properties on the ObjectListView itself or on the columns that are used within the list. Some configuration cannot be done through properties: these more complex configurations are done by installing delegates (more on this later). Once the columns and control are configured, putting it into action is simple.
Hope this helps.

this way i do it. here i am giving my full code. have a look and ask me if u have any confusion. thanks

Display data on grid from multiple tables in c# while using join in stored procedure

I am writing code in C# where I want to select data in datagrid from multiple tables with a relation... Here I have a Client & Item_Configuration as parent table and Item_Order as child table which has the foreign keys from Client and Item_Configuration, I just want to fetch data from all three tables and display on a datagrid
My stored procedure is:
ALTER PROC [dbo].[Full_SP]
#clientName varchar(50) = null,
#itemName varchar(50) = null,
#clientId_FK varchar(50) = null,
#operation int
AS
BEGIN
SET NOCOUNT ON;
if #operation = 2
BEGIN
SELECT
Client.clintName, Item_Configuration.itemName,
Item_Order.orderId, Item_Order.orderDate, Item_Order.quantity,
Item_Order.status, Item_Order.totalPrice
FROM
Item_Order
INNER JOIN
Client ON Item_Order.clintId_FK = Client.clientId
JOIN
Item_Configuration ON Item_Order.itemId_FK = Item_Configuration.itemId
END
END
And my function of search to data grid is in C# i.e.
private void btnSrchFull_Click(object sender, EventArgs e)
{

try
{
conn1.ConnectionString = "server=.\\ms2k5;database=Info_Connect;Trusted_Connection=true";

fullfill.Quantity = Convert.ToInt32(myReader["quantity"]);
fullfill.Status = myReader["status"].ToString();
fullfill.TotalPrice = Convert.ToDouble(myReader["totalPrice"]);
return fullfill;
}
and I created a class for property i.e.
class FullFill
{
public string orderNo;
public string clientName;
public DateTime orderDate;
public string itemName;
public int quantity;
public double totCost;
public string status;
public string OrderNo { get { return orderNo; } set { orderNo = value; } }
public string ClientName { get { return clientName; } set { clientName = value; } }
public DateTime OrderDate { get { return orderDate; } set { orderDate = value; } }
public string ItemName { get { return itemName; } set { itemName = value; } }
public int Quantity { get { return quantity; } set { quantity = value; } }
public double TotalPrice { get { return totCost; } set { totCost = value; } }
public string Status { get { return status; } set { status = value; } }
}
}
The problem is that I am only able to find data from child table(Item_Order) I am not getting data from parent Tables.
