Marcus,

In playing around with the API I have run into the same problem, however I discovered that a declared API call can have an accountKey hard coded into the constructor. So what I did was declared one EveAPI without a accountKey to fetch a list of accounts, and then looped through the accounts using a second EveAPI object to fetch the data. Like so...:

Dim eveAPI As New EveAI.Live.EveApi(keyID, vCode, characterID, 1000)
Dim eveAccounts As List(Of EveAI.Live.AccountBalance) = eveAPI.GetCorporationAccountBalance

For i As Integer = 0 To eveAccounts.Count - 1
Dim iAccountKey As Integer = eveAccounts.Item(i).AccountKey
Dim eveAPI_Wallets As New EveAI.Live.EveApi(keyID, _
vCode, _
characterID, _
iAccountKey)

Dim eveJournal As List(Of EveAI.Live.JournalEntry) = eveAPI_Wallets.GetCorporationWalletJournal()
Dim eveTransactions As List(Of EveAI.Live.TransactionEntry) = eveAPI_Wallets.GetCorporationWalletTransactions()


iAccountKey = Nothing

eveJournal = Nothing
eveTransactions = Nothing

eveAPI_Wallets = Nothing
Next i


However the one thing that I have been able to determine is that the GetCorporationWalletJournal() function returns the default number of rows from CCP's API call, 50 rows, and there seems to be no way to itterate through the data sets to collect more rows. CCP has to options, one is FromID and the other is rowCount. RowCount by default is 50, but can go up to 2,560, since I am ever only getting 50 rows back I'd be willing to guess this value is not being passed. Also, the FromID sets the row at which the pulls starts going back in time from. So if you have 2565 rows in total, you could set it at the 2,560th row and get that plus the remaining 5 rows.

With that, I'd like to either suggest or offer up my assistance in modifying the GetCorporationWalletJournal() and GetCorporationWalletTransactions() functions to accept the "fromID" and the "rowCount" values that CCP accepts and input parameters to the API.

Hope this helps and at least makes a little sense. If you have any questions hit me up in game or shoot me a note and I'll help as I can.

Fly safe!

I'm trying to populate a list with items present in market

comboBox2.Items.AddRange(api.EveApiCore.ProductTypes.ToArray());

But there are some items like "#system" or "planet (temperate)" etc. How to get real market items only?

The links of the first thread works ;)

Nuq,

The best thing that I can suggest is to create data table object and set it up with a column for each piece of information you want to capture. Then create a for loop to process through the journal entries. Once you have completed that process you can set the data grid's data source equal to the data table and then bind the data sources. For the sake of this example I will assume you are doing this on the individual level and not the corporate level, I have also assumed that you have created an API object and passed it the parameters required to get it to work.

Once you have that taken care of you need to setup a container to collect your data into, in this case if you are going straight to a data grid you can simply build a data table like so:

Dim eveOutput As New DataTable
eveOutput.Columns.Add("accountKey")
eveOutput.Columns.Add("Date")
eveOutput.Columns.Add("TransferType")
eveOutput.Columns.Add("GivingPartyName")
eveOutput.Columns.Add("ReceivingPartyName")
eveOutput.Columns.Add("AdditionalDataName")
eveOutput.Columns.Add("Amount")
eveOutput.Columns.Add("Balance")
eveOutput.Columns.Add("Reason")
eveOutput.Columns.Add("TaxAmount")

eveOutput.Columns("accountKey").DataType = System.Type.GetType("System.Int32")
eveOutput.Columns("Date").DataType = System.Type.GetType("System.DateTime")
eveOutput.Columns("TransferType").DataType = System.Type.GetType("System.String")
eveOutput.Columns("GivingPartyName").DataType = System.Type.GetType("System.String")
eveOutput.Columns("ReceivingPartyName").DataType = System.Type.GetType("System.String")
eveOutput.Columns("AdditionalDataName").DataType = System.Type.GetType("System.String")
eveOutput.Columns("Amount").DataType = System.Type.GetType("System.Decimal")
eveOutput.Columns("Balance").DataType = System.Type.GetType("System.Decimal")
eveOutput.Columns("Reason").DataType = System.Type.GetType("System.String")
eveOutput.Columns("TaxAmount").DataType = System.Type.GetType("System.Decimal")

Once you have done this you can simply execute the call to the API to collect the journal entries, and then process through them like so:

Dim eveJournal As List(Of EveAI.Live.JournalEntry) = eveAPI_Wallets.GetCorporationWalletJournal()
For Each eveEntry As EveAI.Live.JournalEntry In eveJournal
Dim tmpRow As DataRow = eveOutput.NewRow
tmpRow("accountKey") = BLAHH
.
.
.
.
.
eveOutput.Rows.Add(tmpRow)
Next

Then once this is done you can finally say this.
dvDataView.DataSource = eveOutput
dvDataView.DataBind()


Hope this gets you started! Please ping me in game if you have any questions!

Thanks a million Thor! that really helped me a lot

I work on a new version with the last bugs that you found and the last API modifications ;)

Is there a way to easily disable the local cache? The problem I'm having is with the getApiKeyInfo() function. If I give it a valid key, and then change the access mask of the key, and then re-run the function it still gives me the old access mask (so if a user of my site puts in a key with the wrong mask, I tell them it's wrong, then they go fix it, it won't recognize the change).

Yes, the local cache is based on the cache of the API itself. So even if you delete the cache file, you will still get the same datas (or nothing if it's on an API that respond only one time).

This scenario is occurring as a result of the local cache:

- User puts in valid keyID and vCode
- EveAI gets chars on key and caches
- User puts in same keyID with no vCode
- even though the eve API would return validation error, EveAI returns same characters

I need a way to make it return nothing if it's an invalid vCode (instead of cached result)

Also, is there a function for the CharacterName.aspx API call? If there is, I can't seem to find it (I need to use it to get the name of a corporation from CorporationID).

It didn't work when I tried it. I put EveAI.Data.zip files in both the application root and the /bin folder where I had the EveAI libraries.

Also I get the exception: Method not found: 'System.Collections.Generic.List`1(EveAI.Live.Corporation.MemberTrackingEntry) EveAI.Live.EveApi.GetCorporationMemberTracking(Boolean)'. --exception edited to make the forums happy.

From the code:

EveApi corpapi = new EveApi(stuff, "morestuff);
var members = corpapi.GetCorporationMemberTracking(true);

That code works without the boolean overload on GetCorporationMemberTracking();
