We just hit this same problem. The PayFlowPro vb project supplied by ASI doesn't work in 15.0.3. I have just seen a document that talks about using the standard ASIPayflowPro.ocx and using the "Custom" gateway setting in system setup, and it will then pass parameters to a "Custom Gateway Handler", but I have found nothing that tells me how to create one.

This issue has now been resolved with a modified PayFlowProXtender.ctl for iMIS versions 15.0.3 and later.
Our thanks to troberts for testing and validating the changes.

Contact me at jfroudeadvsol.com for details..

I am able to get this fixed and able to get ocx working for custom gateway.

just add this ...

Public Function nCCQuery(ByVal strOrderID As String, ByVal strCashAccount) As String
    On Error GoTo CCerror:
   
    'nCCQuery = GetCachedField()
   
    'nCCQuery = gloStrOrderID
Exit Function
CCerror:
    nCCQuery = "TIMEOUT" & vbFormFeed & vbFormFeed & vbFormFeed & strOrderID
End Function
 

For your information

This is the set of information passed from imis to ocx call

    'BillToId=xxx;
    'CustomerId=xxx;
    'Amount=999.00;
    'CardNumber=4007000000000027;
    'CardExpiryDate=1212;
    'CardName=Name;
    'CardCSC=123;
    'CardIssueNumber=;
    'CardIssueDate=;
    'PONumber=;
    'InvoiceNumber=0;
    'CashAccountCode=XXXX; (CAsh Account)
    'ShipFromZip=;
    'ShipToZip=99999-9999;
    'BatchNumber=;'
 

This is how you capture the data from imis in the ccAuth_custom function

    Set params = mod_Common.BuildDictionaryFromNameValueString(strParameters)
    numParams = params.Count
   
    strCardNumber = params.Item("CardNumber")
    strCardExpiryDate = params.Item("CardExpiryDate")
    strAmount = params.Item("Amount")
    strCardCSC = params.Item("CardCSC")
    strCashAccountCodes = params.Item("CashAccountCode")
 

This is how you get name and address

      'Note this is only for the Discouver card - all others will ignore it
    RaiseEvent GetValue("lvSession.SQLHostName", DSN)
    RaiseEvent GetValue("lvSession.SQLDatabase", Db)
    RaiseEvent GetValue("lvSession.SQLUserId", UserID)
    RaiseEvent GetValue("lvSession.SQLUserPassword", Password)
    RaiseEvent GetValue("fBtId", strBT_ID)

    Set rsAddress = New ADODB.Recordset
    rsAddress.CursorLocation = adUseClient
    rsAddress.LockType = adLockReadOnly
    rsAddress.ActiveConnection = "PROVIDER=MSDASQL;dsn=" + DSN + ";uid=" _
        & UserID + ";pwd=" + Password + ";database=" + Db + ";"
    rsAddress.Open "select Name.First_Name,Name.Last_Name, Name_Address.ADDRESS_1, Name_Address.ADDRESS_2, Name_Address.CITY, " _
    & "Name_Address.STATE_PROVINCE , Name_Address.ZIP, Name_Address.COUNTRY " _
    & "From Name, Name_Address " _
    & "where Name.ID = '" & strBT_ID & "' " _
    & "AND Name.BILL_ADDRESS_NUM = Name_Address.ADDRESS_NUM"
 

    strFirstName = rsAddress!First_Name
    strLastName = rsAddress!Last_Name
    strCardAddress = rsAddress!ADDRESS_1 & " " & rsAddress!ADDRESS_2
    strCardCity = rsAddress!CITY
    strCardZip = rsAddress!ZIP
    strCardState = rsAddress!STATE_PROVINCE
    strCardCountry = rsAddress!COUNTRY
 

you can then code the calling of custom gateway dll and authenticating.

Please let me know if you have any question on this.

This is what I did which may be helpful.

The ASIPayForFlow.ocx from imis patch or imis install.

Copy that into you local machine and open a test vb project and add this ocx as a component.

Then you can add this component into a form.

in the form add a button and and code like this

    Dim dummy As String
    dummy = PayFlowProXtender1. will show all the property and methods.

This way you can verify all the functions are having the same parameters.

if you don't find them then you can add dummy function.

Thanks Venky
