I have executed my query in VB with:


I now want to count the number of returned rows so that I can say:IF rows_returned = 1 then login else deny
I think you get the idea.P.S. I know this is not the most secure method of login but I do not want to use the ASP.NET configuration manager as I like to understand what is happening. I am starting off very simple and I shall work up from there.

Forms Data Controls :: Gridview Row Count / How To Get A Count Of The Number Of Rows That Are Returned

Dec 17, 2010

When a user submits the query to SQL when clicking a button I need to get a count of the number of rows that are returned. Which event does the gridview.count code need to be place in?

Right now I have it in the btn_click event, but in order to get it to count the rows you have to hit the button twice since the query is not returned yet. Here is my code.

Security :: Filtering The Rows Returned By Membership.GetAllUsers()?

Dec 22, 2010

In our asp.net application, we use Membership.GetAllUsers() in order to allow the administrator work with the site's membership.

Is there a way to filter the rows returned by Membership.GetAllUsers() method? I'd like to be able to have a textbox where (part of) the user's first name / last name is entered and then call GetAllUsers() - or a different method - to get only the users whose name begins with value in the text box.

SqlHelper.ExecuteReader Results Varying And Unexpected When Certain Number Of Records Are Returned?

Jul 4, 2010

Note: You may not need to read the whole thing to know what's wrong... skip down to the part about the 3 scenarios if you'd like. Only read the begin if you'd like some background info on how I've tried implementing this and where the errors occurred.To begin with, I'm trying to retrieve a list of Clients stored in the CRM_Clients table for a given callerId.I retrieve the clients from my Controller with the SelectLiveClientsForCaller method. The message is then passed on to the DAL through the static Instance method in the DataProvider class:

public List<Client> SelectLiveClientsForCaller(int callerID)
List<Client> results = new List<Client>();

Bulkinsert From CSV Into Db (C#) -> Max Number Of Rows In A Web Application?

Apr 28, 2010

Web application - C#, .Net, SQL 2k5.I recently used bulkinsert on an other application and I thought I would like to give it a try.

I am going to receive a CSV file with 1000 rows, which will most likely add 500 000 (that is five hundred thousand) records in the database.I don't have any idea yet about this huge amount if it's going to work out well. I am afraid that it will time out.

I didn't do any testing yet, but I am pretty sure it would time out eventually.

Is there a way to make it not time out (I don't know ... split the bulkinsert into 1000 pieces :D) or I should try to do something like BCP, with a SQL job ...
