I am creating a REST Service project (just for learning purpose) and using Bing Map... This is what I want to accomplish...I am sending my current location (Latitude and longitude) to the service and I want to find out all the nearest Mac Donalds (for example) within 1 mile range from my current location and the distance and the time it will take me to get each Mac Donalds... I know there are BING MAP APIs which I can use to accomplish ...
But I never used BING map or rest service before... so can anyone please tell me the Bing Map method/API names which take latitude and longitude as argument and retrun the info that I mentioned above.

Thanks.

Somewhat embarrassed: how do I get the dotnet framework?

Guys,

Create a console application. Select the project name in the solution explorer and Alt-Enter or right-click the properties and select the Application tab. Change the Target Framework to say 3.5 or something else other than 2.0. Paste this line into the Main method:

Console.WriteLine("Version=" + Assembly.GetExecutingAssembly().ImageRuntimeVersion);

and run it. I was sort of expecting to see it display the target framework I selected. Instead it displays v.2.0.50727 even though my target framework was set to 3.5. Obviously, I've misunderstood that line of code. Does anyone know what I can do to get the target version I selected? I don't want to do anything as a result of getting it so I just want to display it. Blush | :O

Odd. I pasted your code into my app, and it gave me

Version=v4.0.30319

Which is what I would expect for a V4.0 C# app.

Are you sure you compiled and ran the right version?
Have you tried a full rebuild?

OG, I did indeed a clean and a full rebuild. Eddy Vluggen's reply after yours might well be the thing that decides what gets returned. I'll rebuild it in VS2012 and see what pops out of the woodwork as my VS2008 only lists upto 3.5.

.NET 2.0 would report the 2.0 framework, but 3.0 and 3.5 are "extensions" to the 2.0 runtime. 4.0 has a new runtime again, so that will report back version 4.

--edit;
There's a distinction between the target-framework, and the supported runtime. If it's a desktop-application, than you'll have an app.config file in there, and an "appname.exe.config" file in your Debug folder.

for (int i = 0; i < 5; i++)
{
   i = int.Parse(Console.ReadLine());
}
Console.Write(i);
Console.ReadKey();

how to get console to print all of the numbers entered (5 numbers)? when i debug this it says that the name 'i' does not exist in current context.

Put the console.write and console.readkey INSIDE the for next loop. Move the } down 2 lines.

i've tried that, it just writes the numbers straight after the entering, i want it to write all 5 AFTER i've entered the fifth number.

Re: need help please

Mycroft Holmes8-Dec-12 1:41

And that make no sense at all, you would have to put the numbers into a container (array/List<>) and then loop through the container and print them!

problem in this code is that 'i' is only defined for 'for loop ' to make it run u have to define i before for loop
ex:
int i = new int();
for (i = 0; i < 5; i++)
{
i = int.Parse(Console.ReadLine());
}
Console.Write(i);
Console.ReadKey();
it will not give any error but don't give u the result u want it should be like this..
static void Main(string[] args)
{
int i = new int();
int []arry=new int[5];
for (i = 0; i < 5; i++)
{
arry[i] = int.Parse(Console.ReadLine());
}
for (i = 0; i < 5; i++)
{
Console.Write(arry[i]+"\n");
}

Console.ReadKey();
}

Just to add to what the others have said - you don't want to do it like that anyway!

for (int i = 0; i < 5; i++)
{
   i = int.Parse(Console.ReadLine());
}

Since i is both the loop control variable and the place you store the value the user entered, if the user enters 4 or above as his first number, it will exit the loop immediately.
You need to separate these two functions into two variables, as well as using an array or List<int>

BTW: It is considered a bad idea to use "magic numbers" such as "5" in your code - when you move to an array, it is too easy to later change one and not the other, causing your application to fail, or crash:

int[] inp = new int[5];
for (int i = 0; i < 5; i++)
   {
   inp[i] = int.Parse(Console.ReadLine());
   }

would be better as:

const int elements = 5;
int[] inp = new int[elements];
for (int i = 0; i < elements; i++)
    {
    inp[i] = int.Parse(Console.ReadLine());
    }

That way, you only have to change the number of elements in a single place, and it all works perfectly.

And as a final thing, if your user enters an alphabetic character instead of a digit, your program will crash. You should always check your user input - they do enter rubbish quite often! Laugh | :laugh:

i wonder how this programs builds without any error?

there are few things you need to check here
1.the variable i is accessible only inside the loop and its local to that loop never accessible outside the loops.
2. the indexer variable i is modified against your input which may alter the loop execution
3. Console.Write is outside the loop so if variable i is acceible outside the loop it will print only the last entered value not all

try modifying your code.
define a new variable to store the read line
and move the Console.Write inside the loop and see the difference

Insert Data to Master/Detail table in Sqlserver 2005 from C# with Foreign key in Detail table

ahmed_one7-Dec-12 20:31

I need some help to make a Order Form in C#. My development environment is:

Microsoft Visual Studio 2010 Ultimate Sql Server Express Edition 2005 Programming Language C# Sample Database = NorthWind (Tables=Orders and OrderDetails)

I've create a Form for order dataentry, which contain Textbox for OrderID, Combobox for Customer, DateTimePickers for OrderDate and ShippedDate and a DataGridView which contains Cokumns OrderID=ReadOnly, ProductID, UnitPrice & Quantity:

In the form load event I've the following code:

private void Inv2_Load(object sender, EventArgs e)
    {


        SetComb();
        connectionString = ConfigurationManager.AppSettings["connectionString"];
        sqlConnection = new SqlConnection(connectionString);

        qryOrd = "Select OrderID, CustomerID, OrderDate, ShippedDate from Orders";
        qryOrdDet = "Select OrderID, ProductID, UnitPrice, Quantity from OrderDetails";

        sqlConnection.Open();
        sqlDataMaster = new SqlDataAdapter(qryOrd, sqlConnection);
        sqlDataDet = new SqlDataAdapter(qryOrdDet, sqlConnection);

        //SET MASTER INSERT/UPDATES
        command = new SqlCommand("INSERT INTO Orders ( CustomerID, OrderDate, ShippedDate) VALUES (@CustID, @OrdDt, @ShipDt) SELECT SCOPE_IDENTITY();");

        command.Parameters.Add("@OrdID", SqlDbType.NVarChar, 15);
        command.Parameters.Add("@CustID", SqlDbType.VarChar, 15);
        command.Parameters["@CustID"].Value = cmbCust.SelectedText;

        command.Parameters.Add("@OrdDt", SqlDbType.DateTime);
        command.Parameters["@OrdDt"].Value = dtOrdDt.Text;

        command.Parameters.Add("@ShipDt", SqlDbType.DateTime);
        command.Parameters["@ShipDt"].Value =dtShipDt.Text;



        sqlDataMaster.InsertCommand = command;
        //string id = command.ExecuteScalar().ToString();

        command = new SqlCommand("UPDATE Orders SET CustomerID = @CustID, OrderDate = @OrdDt, ShippedDate = @ShipDt WHERE OrderID = @OrdID");

        command.Parameters.Add("@OrdID", SqlDbType.NVarChar, 15, "OrderID").Value = txtOrdID.Text; 
        command.Parameters.Add("@CustID", SqlDbType.VarChar, 15, "CustomerID").Value = cmbCust.Text;
        command.Parameters.Add("@OrdDt", SqlDbType.DateTime).Value = dtOrdDt.Text;
        command.Parameters.Add("@ShipDt", SqlDbType.DateTime).Value = dtShipDt.Text;
        sqlDataMaster.UpdateCommand = command;


        //SET DETAILS INSERT/UPDATES
        commandDet = new SqlCommand("INSERT INTO OrderDetails (ProductID, UnitPrice, Quantity) VALUES (@PrdID, @Up,@Qty)");

        //commandDet.Parameters.Add("@OrdID", SqlDbType.NVarChar, 15, "OrderID").Value = txtOrdID.Text; ;  
        commandDet.Parameters.Add("@PrdId", SqlDbType.NVarChar, 5, "ProductID");
        commandDet.Parameters.Add("@Up", SqlDbType.VarChar, 50, "UnitPrice");
        commandDet.Parameters.Add("@Qty", SqlDbType.VarChar, 20, "Quantity");
        sqlDataDet.InsertCommand = commandDet;

        commandDet = new SqlCommand("UPDATE OrderDetails SET ProductID = @PrdID, UnitPrice = @Up, Quantity = @Qty WHERE OrderID = @OrdID");
        commandDet.Parameters.Add("@OrdID", SqlDbType.NVarChar, 15, "OrderID").Value = txtOrdID.Text; ;  
        commandDet.Parameters.Add("@PrdId", SqlDbType.NVarChar, 5, "ProductID");
        commandDet.Parameters.Add("@Up", SqlDbType.VarChar, 50, "UnitPrice");
        commandDet.Parameters.Add("@Qty", SqlDbType.VarChar, 20, "Quantity");
        sqlDataDet.UpdateCommand = commandDet;

        sqlComBldMaster = new SqlCommandBuilder(sqlDataMaster);
        sqlComBldDet = new SqlCommandBuilder(sqlDataDet);

        dt = new DataTable();
        dtDet = new DataTable();


        dt.Clear();
        dtDet.Clear();


        sqlDataMaster.FillSchema(dt, SchemaType.Source);
        sqlDataDet.FillSchema(dtDet, SchemaType.Source);

        dtDet.Columns["OrderID"].AutoIncrement = true;
        dtDet.Columns["OrderID"].AutoIncrementSeed = -1;
        dtDet.Columns["OrderID"].AutoIncrementStep = -1;
        ds = new DataSet();
        ds.Tables.Add(dt);
        ds.Tables.Add(dtDet);
        ds.EnforceConstraints = false;



        DataRelation rel = new DataRelation("OrdersRel", ds.Tables["Orders"].Columns["OrderID"], ds.Tables["OrderDetails"].Columns["OrderID"]);
        ds.Relations.Add(rel);

        bs = new BindingSource();
        bsDet = new BindingSource();

        bs.DataSource = ds;
        bs.DataMember = "Orders";

        bsDet.DataSource = ds;
        bsDet.DataMember = "OrderDetails";


        dgInvDet.AutoGenerateColumns = false;

        dgInvDet.Columns["ProductID"].DataPropertyName = "ProductID";
        ProductID.DataSource = dm.GetData("Select * from Products order by ProductName");
        ProductID.DisplayMember = "ProductName";
        ProductID.ValueMember = "ProductID";
        dgInvDet.Columns["UnitPrice"].DataPropertyName = "UnitPrice";
        dgInvDet.Columns["Quantity"].DataPropertyName = "Quantity";   

        dgInvDet.DataSource = bsDet;



    }


public void SetComb()
    {
        cmbCust.DataSource = dm.GetData("Select * from Customers order by CompanyName");
        cmbCust.DisplayMember = "CompanyName";
        cmbCust.ValueMember = "CustomerId";
        cmbCust.Text = "";



    }

"Dm.GetData" is the Data Access class method created for the purpose of just retrieving reocrds...

And in the Save button click event:

private void btnSave_Click(object sender, EventArgs e)
    {


     dt.EndInit();
    rec = sqlDataMaster.Update(ds.Tables[0]);
    rec += sqlDataDet.Update(ds.Tables[1]);
     //recDet = sqlDataDet.Update(dt);

     ds.AcceptChanges();


     MessageBox.Show(rec + " record(s) applied...." );

     ds.EnforceConstraints = true;

    }

What I need is to save the Data to Sql Server in respective table (Orders and OrderDetails) which my code can't seems to do it and it shows error that Foreign Key cannot be null...Because OrderDetails table also needs OrderID which is Foreign Key, and I am unable to understand how can I get the OrderID, as it is Auto generated after data is inserted in Database.

Please help me on this problem to save the data in database with this foreign key issue...

Any help will be much appreciated.

Thanks

Ahmed
