Hi all, I'm in an environment of VB.NET, ASP.NET and Novell eDirectory 8.5*. What I need to do is to retrieve all customers (about 10000+) with their firstname and lastname. I tried to use System.DirectorySearcher, but its performance of retrieving and looping thru such big amount of data to display on .aspx page is very very slow, especially looping thru the SearchResultsCollection took a lot of time. Back in VB6 world, I had some working code that used ADO (Command & RecordSet, etc) to query the same LDAP server. Then I wonder if ADO.NET can work the same way, that's where the following test code came from. Also I wonder if ADO.NET, particularly OleDbDataReader (or maybe OleDbDataAdapter), can speed things up. If yes, the result of DataSet will make things such as binding to a dropdown much easier. The following is my test code, but it errors out in the bold section. (maybe I used dr in a wrong way?) Does anybody know how to make it work? Anybody can provide a good working example? (I have been googling for it , but can't find one) In a word, any of your input will be great!! Thank you!!
