Lorelei Symphony's questions

I have the following code in C

int main(int argc, char *argv[]) {
   int row=2, col=3, f,c;
   char array[row][col] = { {'A', 'B', 'C'}, {'a', 'b', 'c'} };

   for(f=0; f<row; f++) {
      for(c=0; c<col; c++)
         printf("%c", a[f][c]);
      printf("\n");

   }

   return 0;
}

Why does this line NOT work like this: char array[row][col] = { {'A', 'B', 'C'}, {'a', 'b', 'c'} };

error: excess elements in array initializer

But why does it DO work like this? char array[2][3] = { {'A', 'B', 'C'}, {'a', 'b', 'c'} };

I have a Products table in a database, with the following fields:

Id int Identity Primary Key

Int Code Not Null

Name varchar(100) Not Null

Price float Not Null

Quantity int Not Null

Fk_Codigo int Foreign Key References Invoice(Codigo);

"manually"(Microsoft SQL Server Management Studio) I inserted 7 records:

INSERT INTO Product(Code, Name, Price, Quantity, Fk_Code) VALUES(10,'Televisor',9000,2,1);

INSERT INTO Product(Code, Name, Price, Quantity, Fk_Code) VALUES(11,'Laptop DELL',15000,3,1);

INSERT INTO Product(Code, Name, Price, Quantity, Fk_Code) VALUES(12,'Refrigerator',20000,4,1); ... etc.

and the iD identity correctly placed the values ​​from 1 to 7 but in my application with Windows Forms, when I insert new products, the iD identity starts enumerating from the number 1,000.

This is how I make the connection:

  public void ProductInsert(int ProductCode, string ProductName, float ProductPrice, int ProductCant, int ProductFk)
  {
     SqlCommand command;
     string query = "INSERT INTO Producto(Codigo, Nombre, Precio, Cantidad, Fk_Codigo) VALUES(" + ProductCode + ", '" + ProductName + "', " + ProductPrice + ", " + ProductCant + ", " + ProductFk + ")";

      try
      {
         connection.Open();
         command = new SqlCommand(query, connection);

         command.ExecuteNonQuery();
      }
      catch(SqlException e)
      {
         MessageBox.Show(e.Message);
      }
      finally
      {
        connection.Close();
      }
  }

It inserts everything fine, except the iD, it should insert 8 but instead it does so starting at 1,000.

Hello people! I am making a graph (with chart) that takes information from a text file for the X,Y axes. my problem is when searching in a text file, numbers.

the structure of my txt file is as follows:

int n_survey;string city;int age;string gender;

ex: 1;Buenos Aires;25;Female

 2;Corrientes;19;Masculino

 3;...

I use Split(';') to skip my separator in that string and my goal is to capture the age of all the records, line by line in the txt file. I have this:

  StreamReader stream = File.OpenText(@"C:\Usuarios\...");
  List<int> list_edad = new List<int>();
  string[] arreglo_cad;
  string cad = stream.ReadLine();

  while(cad != null)
  {
     arreglo_cad = cad.Split(';');
     list_edad.Add(Convert.ToInt32(arreglo_cad[2]));
     // ...[2] porque es la posicion de las edades
     cad = stream.ReadLine();
  }

  foreach(var item in list_edad)
  {
     if(item >= 16 && item <= 30)
        ++cont1;
     else
        ++cont2;
  }

but the list is not saving the values, any solution?

Hello people! I am making an image viewer. I load the names of my image files into a ComboBox in the Load of the form and pass them to a PictureBox in the SelectedIndexChange event of the ComboBox. all good there until I added a ToolStripStatusLabel to display the path of my file; (the only thing that changes is the name when I pass the image, because they are all in the same directory) or well, that's the idea because it occurred to me to do it this way:

         private void BarradeRuta_LocationChanged(object sender, EventArgs e)
         {
              BarradeRuta.Text = Path.Combine(@"mi ruta....", 
                                                         ComboBox1.SelectedItem.ToString());
         }

but when starting the application with the debugger, it throws me an error saying that the ComboBox is throwing null.

I hope you can help, thanks in advance.

hello! good evening, I am using Sylius for academic purposes on ubuntu server 16.04 i386. I run the server with apache2 and I need to enable SSL security for my site but with apache and from what I have investigated I need several files including some with a .crt extension but I don't know where to get it or how to write it and the Sylius portal does not provide information about. I am new to this e-commerce thing. I hope you can help me; Thanks in advance.

People, good evening, I have this piece of code that, in summary, with an array of size 2, that condition works great, but if I give the "real estate" array more than 3 in size, then I get the error- what I want to do is verify that a new key is not equal to a previously entered one "Check()" takes care of that as additional data, the error pops up (for example with 4 spaces) when I add a new key in index 1. I am not using get, set, this, is that why? I am new to POO at most I have invested 48hrs. Labels(); is nothing more than WritLine's saying that the key already exists, 1 ReadKey() and 1 Clear();
