Ive created a program that uses a SQL select statement to retrieve certain data from an access database, such as SELECT DATE WHERE Score=10;. This works if the item is specified as 0 but will only retrieve the first result, and im using navigation buttons so i want to be able to view all of them one at a time. So i tried changing item to the column the data is located in (which is 1) and the row will vary depending on what button is pressed. but i now get an error message saying "cannot find column 1"

I know it's possible in asp.net to create a custom error page in a web app, by putting the following line in the web.config: <customErrors mode="RemoteOnly" defaultRedirect="frmErrorPage.aspx" />
I have had to do this for my web app, since it is clearly much tidier than letting the program bomb out with it's ugly default error page. My custom error page just has the customer's logo and a brief message saying "Error has occurred. Please return to homepage"The trouble now is that I have no way of knowing what caused the error, when a customer reports it.
Is there a way to make the actual error message appear on this custom error page too?

I need to find rows in resultsets that have every column without null.these resultsets got variable number of columns.currently, the only way that I can think of is creating a view on each resultset and filter this way:
select field1, field2, field3, field4, ... from "huge query" where field1 is not null and field2 is not null and
[code]....
and then in a storeproc/function or .net code(c# / vb.net) loop through all rows / columns and flag or remove every row that got any null?

I have a datagridview and the user wishes to key some text in a text box and press a find button.The text to be looked for could exist in any columns in the grid (I want to exclude hidden columns).The search is to start at the row the user is currently at. If it gets to the bottom of the grid and still not found the the search would start from the first row of data.
If a match is found then the row with a matching value is to be highlighted.I've looked at using the position and find properties of my binding source but I think this will only let me find on one column and only from the top?Do I need to programmatically loop through the rows in the datagridview and search for the text or may there be a better method?
