Lianja and OleDB

[HankFay]

In theory, OleDB is just another activex class. (As to why I would care: let's just say it's an important edge condition.)

Anyway, the following code runs from within VFP (after having moved the northwind directory from vfp samples to c:\temp, so I didn't have to mess with progra~1 etc): The driver itself is downloaded from here: http://www.microsoft.com/en-us/download/details.aspx?id=14839

oConn = createobject("ADODB.Connection")oRS = createobject("ADODB.Recordset")
lcConnString = "Provider=vfpoledb;Data Source=C:\Temp\Northwind\northwind.dbc"
oconn.ConnectionString = lcConnString
oconn.Open()
oRS.Open("select * from customers",oconn)
? oRS.Fields("companyname").Value
oRS.Movenext()
? ors.Fields("companyname").Value

This works in VFPl In Lianja, oRS.Fields(....) produces an error: METHOD 'FIELDS' not found.

Is this an infelicity in ActiveX compatibility, or is it something special about the "ADODB.Recordset" class?

thanks,

Hank

You can SET DEBUG ON and you will see helpful information about what the ActiveX is exposing and how Lianja is interacting with it.

Wow: that's cool! That (debug_client.txt) has almost all the informaton needed for intellisense (except the names of the parameters).

Anyway, here's the entry for Fields of the Recordset class:


File ../../rco_activex.cpp at line 225 PROPERTY name=Fields type=IDispatch*

Looks like a pointer to IDispatch, if I'm reading it right.

thanks,

Yes its returning it a property not a method. Thats the issue right there. Ticket it i'll see if i can proxy it as method.

This is an old post but this should all be working as expected in v1.3.
