Saving Image into database using angularjs

Aug 16 2017 7:11 AM

hi all,

i hv a piece of code , please go thru the below code and help me how to save image into database.

Backend:

=====

create table Employee(empid int primary key,name varchar(max),age int,gender varchar(max),designation varchar(max),mobile int,image varbinary(max))

Csharp code:

========

Emp.cs:

=====

public class Emp

{

public int ID { get; set; }

public string Name { get; set; }

public int Age { get; set; }

public DateTime DOB { get; set; }

public string Gender { get; set; }

public byte[] image { get; set; }

public string Designation { get; set; }

public string Mobile { get; set; }

}

========

DAL logic:

----------

public void SaveEmp(Emp emp)

{

string cs = ConfigurationManager.ConnectionStrings["DBCS"].ConnectionString;

SqlConnection con = new SqlConnection(cs);

con.Open();

string save = "insert into Employee values(@empid, @name, @age,@designation, @mobile,@gender,@dob)";

SqlCommand cmd = new SqlCommand(save, con);

cmd.Parameters.AddWithValue("@empid", emp.ID);

cmd.Parameters.AddWithValue("@name", emp.Name);

cmd.Parameters.AddWithValue("@age", emp.Age);

cmd.Parameters.AddWithValue("@designation", emp.Designation);

cmd.Parameters.AddWithValue("@mobile", emp.Mobile);

cmd.Parameters.AddWithValue("@gender", emp.Gender);

cmd.Parameters.AddWithValue("@dob", emp.DOB);

cmd.Parameters.AddWithValue("@dob", emp.Image);

cmd.ExecuteNonQuery();

con.Close();

}

public void UpdateEmp(Emp emp)

{

string cs = ConfigurationManager.ConnectionStrings["DBCS"].ConnectionString;

SqlConnection con = new SqlConnection(cs);

con.Open();

sstring update = "update Employee set name=@name, age=@age,designation=@designation, mobile=@mobile,gender=@gender,dob=@dob ,image=@image where empid=@empid";

SqlCommand cmd = new SqlCommand(save, con);

cmd.Parameters.AddWithValue("@empid", emp.ID);

cmd.Parameters.AddWithValue("@name", emp.Name);

cmd.Parameters.AddWithValue("@age", emp.Age);

cmd.Parameters.AddWithValue("@designation", emp.Designation);

cmd.Parameters.AddWithValue("@mobile", emp.Mobile);

cmd.Parameters.AddWithValue("@gender", emp.Gender);

cmd.Parameters.AddWithValue("@dob", emp.DOB);

cmd.Parameters.AddWithValue("@dob", emp.Image);

cmd.ExecuteNonQuery();

con.Close();

}

public void DeleteEmp(Emp emp)

{

string cs = ConfigurationManager.ConnectionStrings["DBCS"].ConnectionString;

SqlConnection con = new SqlConnection(cs);

con.Open();

string delete = "delete from Employee where empid=@empid";

SqlCommand cmd = new SqlCommand(delete, con);

cmd.Parameters.AddWithValue("@empid", emp.ID);

cmd.ExecuteNonQuery();

con.Close();

}

hide control without consuming space in xcode using swift?

After max characters per line in textarea, text in next line
