i have a db with two simple tables:
tbl_events:
-Event_ID int
-Event_Name varchar
-Event_Organiser varchar tbl_events_organisers
-Organiser_ID int
-Organiser_name varchar
In event_organiser of tbl_events i want to store the organiser_ID's of the second table in an array, so a record in the first table will like something like:
-Event_ID=18
-Event_Name=My event name
-Event_Organiser= 15,31,109,21
in ASP.net website C# code
example:
in SQL server, I have table TaxTable with column named TaxID, SalaryFrom like this:
TaxID SalaryFrom
1 1
2 2083.00
3 2500.00
4 3333.00
5 5000.00
6 7917.00
is there a way to store the values under salaryfrom column into an array?
note: In C# , Im using system.data.common.DbProviderFactories
this is so that I can read data from both sql server and mysql
I have a GridView where some of the BoundFields have a CssClass applied:
<asp:BoundField ... ItemStyle-CssClass="foobar">
In the rendered HTML it looks like <td class="foobar">
But when I try to read the CssClass programatically in an event like RowCreated or CheckboxChanged or PageLoad it returns nothing:
For Each row As GridViewRow In gv.Rows()
For Each cell As TableCell In row.Cells()
ltlMsg.Text += cell.CssClass
Next
Next
(gv is my GridView and ltlMsg is just a Literal for displaying the results)
If I replace cell.CssClass with cell.Text it does display results, so the code is running.
If I change it to cell.CssClass="test" it does set the class of the <td> elements. It just can't seem to read them.
I must have missed something obvious - I've tried putting it in various different events but nothing seems to work. I assume the CssClass must get set at a later point in the event cycle than I have tried. Can anyone recommend a link to documentation that shows the order in which all the events fire?
Eventually I want to use this to show or hide certain columns in the GridView based on whether a CheckBox (outside the GridView) is checked or not.

View 2 RepliesI have setup a webservice that returns an array of Transaction objects (Transaction being a custom class I created). Each Transaction object has a range of properties (strings, dates etc) and a couple of other embedded objects. I have tested this from another asp.net application and I can consume the webservice fine and access all the objects etc.This webservice is returning Transaction objects that will be loaded into a database on the client side. The objects all come back in an array from the webservice, which needs to be handled via SSIS 2008 and loaded into a database on the client side. The question is, how do you configure the SSIS package to read and handle the incoming array and the custom objects within?
View 1 RepliesI have a gridview control that displays expenses claims received from clients. I have a template field that contains a checkbox - if this is ticked, a value from the gridview is added to a variable and this is outputted to a label control.
What I then want to do is to update the database according to which row has been ticked. I have so far the following code that adds each value to an array, which I was then hoping to access in the sql query i.e. Update table set value = value where id = (id's added to array)..
Code as follows - so far I'm just displaying the count of values in the array to make sure they are actually being added:

View 4 RepliesI have a dataset that has around 5 rows. I also have another Datarow() array that has an additional 3 rows which I would want to add to the dataset. The structure of both the Dataset Rows and the Datarow arrays are the same.

using c#, i have an array where i want to test every single line of this array if it is already contained in a table of a database. if not, i do an insert. the test if the line is already in the table is performed using update, if update fails i insert the line. this works BUT the table contains 100000 entries, the arrays i want to compare/insert contain appr. 5000 entries. so, i is really slow and takes minutes.

I'm putting together a way to cull out bad emails from my table.
I have an email field, of course, and a 'fail' field (integer)
Each time I send out an email, I get a bunch of emails back that the email addresses were undeliverable, so I'd like to (manually), enter them all into an array (or whatever), and then run a stored procedure which updates the 'fail' field by 1
I'm looking for both on the SQL side (I have an sProc that does the deed one at a time - just need the logic to do it in a batch like this), and how to do it in the web page.....
I'd like to write and read TCP Streams directly without any modifications by ASP or IIS. Is this possible?
Edit: Goal is to provide communication between a program and a server. Data exchange between them is less then 25 bytes per connection (in default case). So Headers will cause more traffic then the real data. I need to use ASP.Net because the owner of the server will not let me execute my programs.
