If i am having 2 dropdownlists, 3 gridview and many more databinding controls in a single form and I am binding different data to those controls, so I need to create stored procedure for every individual operation OR stored procedures are mainly use for inserting,updating or deleting.cos it is a bad habit to use inlinecode.
if I create sp for every single operation there might be a lots of sp in my databse... it is good for being a programmer or not.
in my case, It is the windows service which in running the long running insert/update on a table and I need to cancel the operation from my ASP.NET application. In the above link Burnsys suggests that one should kill the Sql server session. Is that really only way and a goood practice to do this? Also, in the same poset can use SqlCommand.Cancel to cancel. However, I am not sure how can I cancel the command from the windows service from ASP.NET application.
I have a small problem, I have created a kind of "Register Form" to insert data into a database.The Textboxes in this form have coded operations on TextChanged(object sender, EventArgs e).So for instance, if one textbox receives "1" and the next one "2" the third textbox automatically sets its text to "3". Because it has a sum operation receveing the input from the other 2 textboxes. This is working quiet well, the thing is that this registerform is made to be filled as fast as possible.When I input some value and then click "TAB" to change to the next Textbox the operationg happens and the typing returns to the first Textbox, I don't know if you can understand me.
I do not understand how this problem happens, and I need help. The code below is very simple. It collects data entered into controls; instantiates a class; then sends the data to a class method for processing. No resulting value is returned to this code.You can see that there are no areithmetic operations performed on the data, but I sometimes get the error "arithmetic operation resulted in an overflow" right here on the last line cRating.SetRating(etc...).
[Code]....
The class method uses the player id values (single) for the two players (iHPlayerID and iAPlayerID) to find their rating values. Calculations are made and the database is updated.Observation 1:I don't want to discuss the class method too much because, and this is the odd part,the code behind breaks before reaching the class. I have inserted a breakpoint at the start of the class method and ran the code. The error occurrs and the class codenever appears.
Observation 2:I mentioned that the class uses the players' ID values to look-up their rating from the database and round that value (single) to an integer. The code works just fine if the integer values of the players and not the same. The code fails and gives the error every time if the integer values are the same. How can this happen if the class code never executes?
i write script to add meta information to mp4 video, when my script try to add mp4 meta information to mp4 file. I/O Error arises and operation terminated possibly cause of "no permission to open file". which permission is required to solve this issue. I am using ASP.NET. windows 7.
I´m making a gridview with a sql query where I also do an upload to an FTP address for each column. It works and several files are being send but after 2 minutes I got "the operation has timed out". I have tried setting this in the web.config but it does not solve it:
httpRuntime maxRequestLength="6024000"
What can I possible to? Is the page timing out due to the sql connection or just the webpage request?
I my web application I perform a time-consuming asynchronous operation. For this, I need to inform user before it starts and after it ends. The latter works as expected, but I cannot make GUI change before asynchronous operation starts. Here is the code snippet:

I have two textBox, one button and one gridview. In one texbox, I enter a value, click the button to add this entry to the gridview and the footer is computing the sum as i add more entries to the gridview.
I also have a textbox outside the gridview that will hold an amount, now I want to perform an operation like...(txtOutsideGridview - gridviewEntry1 - gridviewEntry2), and display the result of this operation inside the footer of the gridview, instead of the sum. How do I go about doing this?
So far all I have been able to do is sum up the total of entries within the Gridview, but that is not my desired operation...here is what my current code looks like
