hi,

I am using

IList<ContractListEntry> contracts = OECContracts.ConvertFromOECContractList();

to get list of contracts and i am getting list of it but i think its not from all the groups so can you tell me how i can get all the contracts from all the groups? becoz i need to have contracts from energy and currency groups.

what the changes required?

to get the full contract list, you need to use OECClient.Contracts property.

Thanks for your quick reply..

Actually i would like to show contract list in dropdown and i have used OECClient object to get all contract as per your suggessions but still i am not getting proper resut. this is my code :

private void PrepareContracts()
{
OECClient contractList = new OECClient();


ContractList contracts = contractList.Contracts;


cbSymbol.ValueMember = "Symbol";
cbSymbol.DisplayMember = "Name";
cbSymbol.DropDownWidth = 200;

BindingSource bs = new BindingSource(contracts, "");
cbSymbol.DataSource = bs;


cbSymbol.Text = string.Empty;
}

contract list is downloaded from OEC Server and is available only after you log in successfully.

Also, there are several thousands of contracts, so I would not recommend to show them all in the combo box - you may want to show only nearest month Contract for each BaseContract .

Thanks for your suggestion.

Can you send me code to bind dropdownbox with contracts of any perticular group?

right now my code is like this :

---------------
IList<ContractListEntry> contracts = OECContracts.ConvertFromOECContractList();
//ContractList contracts = contractList.Contracts;

cbSymbol.ValueMember = "Symbol";
cbSymbol.DisplayMember = "Name";
cbSymbol.DropDownWidth = 200;

BindingSource bs = new BindingSource(contracts, "");
cbSymbol.DataSource = bs;

-----------------------

so send me the code like this only. i have once tried with oecclient object but it was showing me error "object reference not found in the object"

if you open the OEC API Example project source code, you can see following code there:

cbContract.Items.Clear();
cbContract.Items.AddRange( GetObjects( oecClient1.ContractGroups["Indices"].Contracts.Values ) );

(Form1.cs, line 141)

You can change code from advanced example:

file contracts.cs, line 23:

m_Contracts = OECClient.Global.ContractGroups["Indices"].Contracts.Values;

if you replace it to

m_Contracts = OECClient.Global.Contracts.Values;

you will have all available contracts there.
