Does ASP, C#, VB.NET have a way to retrieve what line its on in code as its processing commands?
Example
1 <%
2 response.write("Your on line " & retreiveCurrentLineNumber)
3 %>
Output: Your on line 2

sub textbox1_lineindexchanged (byval ....) Handles Textbox1.Lineindexchanged
'do code based on the current line
end sub

View 2 RepliesUsing the following code, a user inputs a date into a textbox control and then clicks a button. A new record is created in table [rms_Report] and then I retrieve the ID of the record that was just added. I pass this ID onto page "CreateReport.aspx" via a response.redirect and query string.
I need to retrieve the UserId of the currently logged in user and insert it into table [rms_Report]. I need this to occur after the new record is inserted, but obviously before the response.redirect. I know how to retrieve the UserId, but I'm not sure how to incorporate into the other code.
