Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim con_str As String = "Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|Database1.mdf;Integrated Security=True;User Instance=True"
Dim con As SqlConnection = New SqlConnection(con_str)
Dim cmd, cmd2 As SqlCommand

Is there any possibility to execute the job in sql server. I want to create the Job. then through the quer i want to execute this Job by passing parameters. can we able to do this.Actucally i want to execute the SP from front end. but suddenly it should respond to the page. but that SP will run for nearly 5 minutes.

basically i have two dropdown boxes to filter data and textbox with stored procedure bound to gridview.i want to be able to query data depending on the selected value passed,either using one or more parameter values.
i would like seperate sqlcommands to chose from depending on which controls i select to pass parameters.
i have included a parameter Select(control id) as this is declared by the wizard for stored procedure.
but i am not sure how it is defined on the page and passed to procedure.
This would seem to be quite a trivial task, however I am having trouble retrieving the identity of the record inserted using the detailsview.insert() in the code behind. It would seem that detailsview.DataKey.Value would contain this value, but it is null after the insert is performed.
I'm trying make FormView insert a new row into a database table via a stored procedure.My code runs without error but nothing appears in the database table.
I have SQL Details View insert statement, I need to have a Condition checked for the Insert Query. The condition is, I do have a table by name table1 with the No of Questions (for Eg: 10). The insert statement shud insert data to the table2 (Another table) only if the no of rows is less than or equal to 10 else it shud give me a message (It has exceeded the no of questions).
I tried to find a LINQ section on this forum, but couldn't, so I'll post this here since is deals with LINQ, C#, MVC, SQL Server, and well...just about everything.
Here's the details....My Application is an ASP .Net MVC 1.0 app, using C# 3.5, SQL Server 2005 Std, and LINQ to Entity.
In my View, I have numerous Html.CheckBox controls, they get passed to my Controller as a string collection via a JQuery Ajax call. The values of each checkbox are seperated by a comma(,). I then Split the string, to get the individual values. The overall purpose to to allow users to build a custom report with only the data elements they have checked the boxes for. Here is my controller:
[Code]....
The part that I am having a problem with is that I only want to Insert the data elements into my DB table for the ones that the user has selected the checkbox for. So, for example, I'd like to do something like this:
[Code]....
I don't know if there is a LINQ switch statement in which I can access outside variables and the columns of the table, or any thing like that.
I want to be able to show the record that was just inserted after add_button_click event. I run the insert from mycommand and then set mycommand2 to run the read to populate a details view. I have a feeling I am going about this the wrong way. The insert fires correctly but the details view does not populate.
i have a form view that takes fields from two tables 'Contract' and 'volunteers', however because i used a query builder,i have to input an insert statement. How do i create an insert statement for two tables in one query?
I'm trying to create multi insert query in single stored procedure along with scope_identity variable. while execute the aspx page getting error "Procedure 'sp_seller_ins' expects parameter'@new1', which was not supplied." I have created stored procedure:

I have a page (i.e. page1.aspx) that a user will select from the record and it will press on the delete button. And it will redirect on another page (i.e. page2.aspx). On page2.aspx, I wrote my query for example
Code: DELETE FROM items WHERE item_id=2 how may I know if the query was successfully processed because I have to redirect again on the first page.
i am developing an application using ASP.NET with C#.Net and SQL SERVER 2005. here i am importing data from excel sheet to database.in my excel sheet some fields have large data.and for those fields i had taken NTEXT as data type in my database.when i am trying to import the data,the fields which have large text are not inserted completly.i.e some data is missing. the field in database accepts the data upto some characters only.what would be the reason for this? and which data type can i use for inserting large data?
I have a series of classes that loosely fit the following pattern:
public class CustomerInfo { public int Id {get; set;} public string Name {get; set;} public class CustomerTable { public bool Insert(CustomerInfo info) { /*...*/ } [code]...
My insert is adding a record to the database in the call to the stored procedure in SQL Server, but a -1 is returned - Shouldn't it return 0 if the insert/update was successful?
Trying to check if an insert of a new record into an SQL table is happening successfully. I can see that the insert is occuring OK but am not getting the verification to happen.
I'm a little new to C#, I'm thinking it may be in the syntax I'm using in my method in the .cs file line 45. Can't seem to fix it right though.
I am using SqlCommand to insert new value to a table. My table has 2 fileds1. IDDT (Auto increment) (numaric)2. Name (VARCHAR)i am runing below code to insert new value
[Code]....
Acording to the table the IDDT value will be inserted automatically. I need to get that value using above code.
I've been searching on the internet about this issue but all studies returns a ID value that is integer. However, in my system primary key field is a GUID, I mean uniqueidentifier. How can I get this value? Should I use SELECT SCOPE_IDENTITY() which is integer ?
i have two sqldatasource controls. one i use to display data in textbox's ,filter'd by a select parameter in page behind code. Once checked, i want to copy this data to the other datasource ,by selecting checkbox.Then display this data in detailsview control.
At present the two datasource controls declared , render data to the page simultaneously during pageload. I want to first check data in textbox's from first source, before second datasource is rendered to screen. note, both are filtered by a page variable. i wish to leave the textbox datasource control in situ, as other controls and code depend on it.The other detailsview datasource is my problem?
I have a Gridview which I'm populating through code behind. A couple of columns of the gridview I've set up to be drop down lists. What I want, is that when I run my Insert query, it takes the drop down list selected value, finds the appropriate ID and uses that ID as part of the insert query.
