Never post your email address in any forum, unless you really like spam! If anyone replies to you, you will receive an email to let you know.
And as for the task:
Start by specifying what you want to do.
Then design your system to the specification.
Create your DB and populate with sample data.
Code your design.
Test.
Repeat from the appropriate stage above until it works.

And don't post a phone number either. That's even more stupid than posting your email address in a public forum. You realize you just posted your phone number so that billions of people can now see it, correct? That includes anyone who wants to call you up and sell you penis enlargement pills.

Try adding the Customers, calling SaveChanges on the context, then add the Companies.
|
|
|
|
|
Company company1 = new Company();
company1.CompanyId = 1;
company1.Name = "abc";
company1.Email = "abc@hotmail.com";
company1.Address = "xyz street";
company1.City = cityState[0];
company1.State = sortedStates.Where(state => state.Abbreviation == cityState[1]).SingleOrDefault();
company1.StateId = 1;
company1.Zip = 2066;
company1.Phone = "949494848";
company1.Customers = new List<Customer>();
Customer customer1 = new Customer();
customer1.CustomerId = 1;
customer1.FirstName = "bikash";
customer1.LastName = "shrestha";
customer1.Email = "bikash@hotmail.com";
customer1.Address = "482 pacific hwy";
customer1.City = "Phoenix,AZ";
customer1.State = sortedStates.Where(state => state.Abbreviation == cityState[1]).SingleOrDefault();
customer1.StateId = 1;
customer1.Zip = 85230;
customer1.Gender = Gender.Female;
customer1.Orders = new List<Order>();
Customer customer2 = new Customer();
customer2.CustomerId = 2;
customer2.FirstName = "prakash";
customer2.LastName = "shrestha";
customer2.Email = "prakash@hotmail.com";
customer2.Address = "482 pacific hwy";
customer2.City = "Phoenix,AZ";
customer2.State = sortedStates.Where(state => state.Abbreviation == cityState[1]).SingleOrDefault();
customer2.StateId = 2;
customer2.Zip = 85231;
customer2.Gender = Gender.Male;
customer2.Orders = new List<Order>();
Order order1 = new Order();
order1.Id = 1;
order1.CustomerId = 1;
order1.Product = "apple";
order1.Date = DateTime.Today;
order1.Price = 5;
order1.Quantity = 1;
Order order2 = new Order();
order2.Id = 2;
order2.CustomerId = 1;
order1.Product = "apple";
order2.Date = DateTime.Today;
order2.Price = 5;
order2.Quantity = 1;
customer1.Orders.Add(order1);
customer2.Orders.Add(order2);
company1.Customers.Add(customer1);
company1.Customers.Add(customer2);
using (var dbCtx = new CustomerManagerContext())
{
dbCtx.Companies.Add(company1); <-- here i get same error now.
dbCtx.SaveChanges();
}
The error details:
Unable to cast object of type 'System.Collections.Generic.List`1[CustomerManager.Model.Customer]' to type 'CustomerManager.Model.Customer'.

OK, now you changed the original post so that there are order. Same problem. Create records for a single table at a time then save the changes.
Create the Companies first and save them, then add Orders and save them.
|
|
|
|
|
could you please help me?
If I first save company first it will be as below
using (var dbCtx = new CustomerManagerContext())
{
dbCtx.Companies.Add(company1);
dbCtx.SaveChanges();
}
company1.Customers.Add(customer1);
company1.Customers.Add(customer2);
customer1.Orders.Add(order1);
customer2.Orders.Add(order2);
how do I now save customer1, customer2 and order1 and order2 using the context?
|
|
|
|
|
I do have a requirement for you when writing code: USE YOUR BRAIN!
Serisously? What's preventing you from putting the other creation objects in the same "using" context? NOTHING! You can call SaveChanges multiple times before disposing the CustomerManagerContext.
So, create your Customers, SaveChanges. Create your Companies, SaveChanges. Create your Orders, SaveChanges, ...
See a pattern there?
|
|
|
|
|
Ok. I did as per you mentioned but I get below error now
using (var dbCtx = new CustomerManagerContext())
{
dbCtx.Customers.Add(customer1);
dbCtx.SaveChanges();
dbCtx.Customers.Add(customer2);
dbCtx.SaveChanges();
dbCtx.Companies.Add(company1);
dbCtx.SaveChanges();
dbCtx.Orders.Add(order1);
dbCtx.SaveChanges();
dbCtx.Orders.Add(order2);
dbCtx.SaveChanges();
}
Entities in 'CustomerManagerContext.Customers' participate in the 'Customer_Companies' relationship. 0 related 'Customer_Companies_Target' were found. 1 'Customer_Companies_Target' is expected.
this is because I have below method
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Entity<Customer>().
HasMany(c => c.Companies).
WithMany(p => p.Customers).
Map(
m =>
{
m.MapLeftKey("CustomerId");
m.MapRightKey("CompanyId");
m.ToTable("CustomerCompany");
});
modelBuilder.Entity<Company>().HasRequired(c => c.Customers).WithMany().WillCascadeOnDelete(false);
modelBuilder.Entity<Customer>().HasRequired(c => c.Companies).WithMany().WillCascadeOnDelete(false);
base.OnModelCreating(modelBuilder);
}
sorry still learning entity framework.

|
|
|
Please remove that OnModelCreating. It's pretty broken; it would require that a customer exist before a company does, and that a company exist before a customer does....

Okay, you have a little work to do on this. even when using POCOs, you need to keep the shape of the database and the limitations of SQL (like field values in tables) in mind. You still use foreign keys to map to complex types, and you cannot insert values into a SQL field that it does not recognize as a native type.
I'm assuming your context class looks like:
public class MyContext : DbContext
{
public DbSet<Customer> Customers { get; set; }
public DbSet<Company> Companies { get; set; }
public DbSet<Order> Orders { get; set; }
}
You have a M:M mapping for customers to companies, and and 1:M for customers and orders (I'm guessing). without seeing the Order class, it looks like our base structure has an few inherent flaws, and will not be able to normalize or even perform proper data access at the moment.
Here's the obvious changes:
public class Company
{
[Key, DatabaseGenerated(DatabaseGeneratedOption.Identity)] [Display(AutoGenerateField = false)]
public int CompanyId { get; set; }
[StringLength(50)]
public string Name { get; set; }
[StringLength(200)]
public string Address { get; set; }
[StringLength(500)]
public string Email { get; set; }
[StringLength(1000)]
public string Phone { get; set; }
[StringLength(50)]
public string City { get; set; }
public State State { get; set; }
public int StateId { get; set; }
public int Zip { get; set; }
public virtual ICollection Orders{ get; set; }
}
public class Customer
{
[Key, DatabaseGenerated(DatabaseGeneratedOption.Identity)] [Display(AutoGenerateField = false)]
public int CustomerId { get; set; }
[StringLength(50)]
public string FirstName { get; set; }
[StringLength(50)]
public string LastName { get; set; }
[StringLength(100)]
public string Email { get; set; }
[StringLength(1000)]
public string Address { get; set; }
[StringLength(50)]
public string City { get; set; }
public int Zip { get; set; }
[Display(AutoGenerateField = false), ForeignKey("State")]
public int StateId { get; set; }
public virtual State State { get; set; }
public virtual ICollection Orders{ get; set; }
public string Gender { get; set; }
Okay, now that the changes are made to those classes, let's look at a possible Orders class. I'll just add the fields to wire the M:M up, I don't know what other fields you have in there. This is assuming that One Customer can have Many Orders, and One Company can have Many Orders, but each Order has only One Customer and only One Company.
public class Order
{
[Key, DatabaseGenerated(DatabaseGeneratedOption.Identity)] [Display(AutoGenerateField = false)]
public int Id { get; set; }
[Display(AutoGenerateField = false), ForeignKey("Customer")]
public int CustomerId { get; set; }
[Display(AutoGenerateField = false), ForeignKey("Company")]
public int CompanyId { get; set; }
public virtual Customer Customer { get; set; }
public virtual Company Company { get; set; }
public Order(){}
public Order(Customer customer, Company company)
{
CustomerId = customer.CustomerId;
CompanyId = company.CompanyId;
}
}
My sample has a parametrized constructor, but that's optional. If you do include one, though, always include a default constructor.
Now let's swing back to the Context class and implement an Update method.
public class MyContext : DbContext
{
public DbSet<Customer> Customers { get; set; }
public DbSet<Company> Companies { get; set; }
public DbSet<Order> Orders { get; set; }
public bool UpdateOrder(Order order)
{
if(Orders.Any(x => x.Id == order.Id))
this.Entry(order).State = EntityState.Modified;
else
Orders.Add(order);
return this.SaveChanges() != 0;
}
public bool UpdateCompany(Company company)
{
if(Companies.Any(x => x.CompanyId == company.CompanyId))
this.Entry(company).State = EntityState.Modified;
else
Companies.Add(company);
return this.SaveChanges() != 0;
}
public bool UpdateCustomer(Customer customer)
{
if(Customers.Any(x => x.CustomerId == customer.CustomerId))
this.Entry(customer).State = EntityState.Modified;
else
Customers.Add(customer);
return this.SaveChanges() != 0;
}
public bool DeleteOrder(Order order)
{
if(Orders.Any(x => x.Id == order.Id))
{
Orders.Remove(order);
return this.SaveChanges() != 0;
}
return false;
}
}
Then just create objects and add them via context.Update().

Hi, thanks for the detailed explaination. In my case, a company can have many customer and a customer can belong to many companies. only customers will have order. Sorry to call this "order". It should actually be called "Job". Would I require making any changes to what you have described above for my situation?

Hi guys,
I'm new to VB6 and also MSMQ. I went through a lot of tutorials online but seems like there is no solution for my question.
I managed to sending from C# to C# or VB6 to VB6 but not from VB6 to C# or vice versa. So I wonder is it a way to do that or there is no way to do this kind of communication.
For example: I want to send this to MSMQ
Dim PropBag As PropertyBag
Set PropBag = New PropertyBag
PropBag.WriteProperty "Customer", "Bob"
PropBag.WriteProperty "Product", "MoeHairSuit"
PropBag.WriteProperty "Quantity", 4
and get the details in C#, there is "Invalid character in the given encoding. Line 1, position 1." error when I use XmlMessageFormatter
Message mes = mq.Receive(new TimeSpan(0, 0, 3));
mes.Formatter = new XmlMessageFormatter(new String[] { "System.String,mscorlib" });
result = mes.Body.ToString();
I also tried to read from the stream but it come out with a weird symbol in my string. Below is the code and this is the output "늓\0\0\b\b휖ꭑ(\0customer\0Bob\0\b\a劑틠4\0product\v\0MoeHairSuit\b調⫳ﾤ.quantity\0"
Message mes;
mes = mq.Receive(new TimeSpan(0, 0, 3));
mes.BodyStream.Position = 0;
byte[] b = new byte[mes.BodyStream.Length];
mes.BodyStream.Read(b, 0, (int)mes.BodyStream.Length);
UnicodeEncoding uniCoder = new UnicodeEncoding();
result = uniCoder.GetString(b);
I get this exception "Cannot deserialize the message passed as an argument. Cannot recognize the serialization format." when using ActiveXMessageFormatter like below
mes = mq.Receive(new TimeSpan(0, 0, 3));
mes.Formatter = new ActiveXMessageFormatter();
result = mes.Body.ToString();
Do you guys have any idea how to do that?
Thanks in advanced

I haven't done any work in VB6 in quite a long time, but I would suspect that you can't use a PropertyBag to do this.
Why are you using VB6 at all since it's been dead for quite a while now?
|
|
|
|
|
I have programs which are in VB6 and communicate using MSMQ. I am trying to migrate the receiver into C# and the sender remains as VB6 cause a lot of my clients are using the VB6 program. So the problem is how can I extract the data send by VB6 which is in propertyBag format using C#?
|
|
|
|
|
After a bit of research it looks like you're hosed. The only viable solution I can find is to create a COM DLL in VB6 that deserializes the object from the MSMQ and then pass the data back to C# through the COM interface.
|
|
|
|
|
Thanks @Dave for your time
|
|
|
|
|
The data sent by VB6 are not at all xml formatted, nor do they use unicode.
Well, you already receive a byte array. Now look into it, compare that with the data you knew you sent from VB6, and do some reverse-engineering. That's a bad job, but it can work.
|
|
|
|
|
Thanks @Bernhard Hiller. The byte array received are same with the one received in VB6 but only VB6 can understand them. C# gave me some weird symbols. In VB6, I just need to assign the byte array back to propertyBag.contents then propertyBag will take care everything for me. Tried to search in internet but cannot get any example on the reverse-engineering. It is a time consuming process so want to check whether there is another easier way to do this

Hi,
I have to write code logic in Inno setup project and want to place all code logic in a separate class. Is it possible in Inno setup.
|
|
|
|
|
This has nothing to do with C#. Try the InnoSetup support forums as they are the best placed people to give you an answer.
