From Pickwiki
Here is a simple VB procedure that shows the OLE connection string needed for UniData connection (you will need to have the Unidata OLE DB client software loaded on your PC)
Sub [[Test_OLE_Connection]]()
Dim cnnConnection
Dim rstTable
Dim strCommand
Dim strConnect
Set cnnConnection = [[CreateObject]]("ADODB.Connection")
Set rstTable = [[CreateObject]]("ADODB.Recordset")
strConnect = "Provider=Informix.[[UniOLEDB]].1;Password=<password>;User ID=<logon ID>;Data Source=<database name in uci.config>"
cnnConnection.Open strConnect
'Sample SQL command
strCommand = "select * from <file name> where ID = '<ID>'"
rstTable.Open strCommand, cnnConnection, , , 0
'rest of your code here
End Sub
