VS 2008 - How To Call A Sproc Over And Over With Sqldatasource
Apr 13, 2010
I have a list of numbers I need to submit one at a time to a stored procedure to add to a table. I don't know any other way around this. The database for this is an AS400 so it's not like using mssql server. I have a connection string and use the SQLDatasource controls to select data because I can select a stored procedure with it to call. Now I need to do an update and if it was just one time of submitting information I would do it the same way. But I need to submit each number till I do them all. How can I do this? Do I still use a sqldatasource control and set the value to be pulled from like a session var and just loop through setting the session and then sqlds.databind over and over? I added a DBML but can't do that with the as400 stored procedures as far as adding them like I do mssql.

I've built a Formview, but need to implement some back end functionality - I have a dataset with stored procedures, and am using ObjectDataSources. I've put an asp:button on the page and called it btnDelete, but how do I call the stored procedure ?
Something along the lines of

I want to be able to click on the Delete button, and have it call the stored procedure to delete the record from the dataset...but I don't know C# well enough to be able to work out what the code should be..

I know the following sproc is vulnerable to SQL injection:
[Code]....
I would like to write a call to this sproc that uses SQL injection to execute the additional command:
[Code]....
That way, I can demonstrate the vulnerability of the sproc to SQL injection and test any revised implementations of the sproc using the same test call.
Problem is, SQL injection is harder than I thought! I just can't seem to do it.
Can anyone provide me with text for the sproc call to execute the additional command?

I'm trying to call a linked server, SS2000 that has NText field and instert that data into an nvarchar(120) field on SS2008.
If I execute the SPROC from SS2008 Management Studio, it works fine. If I try to call the SPROC from my ASP.NET 3.5 web application, I don't get any errors, but the data doesn't get updated.
I'm using the following SPROC:
CREATE PROCEDURE [dbo].[usp_UpdateMilestoneDescription]
@UID int
AS
BEGIN

I have a datasource that is connected to a stored procedure and I need to do a postback on the web page but do not want the sqldatasource to do a databind. What I am doing is when I change a dropdown box to fill in some textboxes with specific dates, I do this on a postback so the textboxes are filled in with the dates. But the SQLDatasource control data binds again and shows new results in my gridview.
Is there any way to prevent this so I can just postback to fill in the textboxes?

I typically don't use the sqldatasource control but trying it out and can't seem to get the delete function working. It doesn't seem to be passing a parameter to my stored procedure. The error I get is: Procedure or function 'sp_DeleteCraigsListEntry' expects parameter '@craigslist_search_id', which was not supplied. Any thoughts?
Code:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataSourceID="ds1" CellPadding="4" DataKeyNames="craigslist_search_id"
ForeColor="#333333" GridLines="None" >
<RowStyle BackColor="#EFF3FB" />
<Columns>
<asp:CommandField DeleteText="x" ShowDeleteButton="True" />
<asp:BoundField DataField="craigslist_search_id" HeaderText="ID"
InsertVisible="False" ReadOnly="True" SortExpression="craigslist_search_id" />
<asp:BoundField DataField="craigslist_search_value" HeaderText="Search Value"
SortExpression="craigslist_search_value" />
<asp:BoundField DataField="craigslist_Search_entry_dt" HeaderText="Entry Dt"
SortExpression="craigslist_Search_entry_dt" />

I am getting error on attempted Databind call to DataList1 with nested SqlDataSource tool after attempting to update or delete a record.
The SqlDataSource control 'sqldsfilelist' does not have a naming container. Ensure that the control is added to the page before calling DataBind.
Here is the aspx page code.

And the code behind....

On my web pages I display the data as mm/dd/yyyy and that is how the user will enter the dates as well. But when I pass the textbox control that has the date in it as a parameter to the SQLDataSource control, I need it to be sent in the YYYY-MM-DD format for the AS400. Is there a way it can be changed in between?

When the data is retrieved through a stored procedure using the SQLDatasource control that is binded to a gridview control, I want to change some data that is in some of the columns. Can i do this in one of the events either in the gridview or data control? I know you can do some formatting on the aspx page side such as dates, etc. but was wondering if I can do it on the vb code side?

I have a sqldatasource control that I want to get the field values from as it is selecting. Is there any way to do this in the dsControl_Selecting event for each record without binding it to any control or formview? I would like to call dsControl.DataBind and retrieve the field values.

When I drag and drop an SQLDataSource control to my new web page it disappears after I set it up.
It exists in Source but I can't see it in Design. I'm doing the same thing I would do in VS 2005 and I can see the control in design view.
Why can't I see the control? I'm new to VS 2008 and .Net 3.5.

I use the sqldatasource control a lot with stored procedures. But this time I'm using some code I found online where I am defining the new sqldatasource in the code and using it. You can see this below. I am getting a NullReferenceException on the first SelectParameters line and not sure why. Do I need to add the parameters different?
Code:
Dim SqlDataSource As New System.Web.UI.WebControls.SqlDataSource()
SqlDataSource.ConnectionString = ConnectionString
SqlDataSource.SelectCommand = "MySprocName"
SqlDataSource.SelectCommandType = SqlDataSourceCommandType.StoredProcedure
SqlDataSource.SelectParameters("Distance").DefaultValue = 25
SqlDataSource.SelectParameters("ZipCode").DefaultValue = "31410"
Dim arg As New DataSourceSelectArguments()
Dim dv As System.Data.DataView = DirectCast(SqlDataSource.[Select](arg), System.Data.DataView)

I'm sure this will need to use javascript but not sure exactly how to do it. I need to count the characters typed in a textbox and when it reaches 10 I want a sub to be called in the code. Or have it click a button on the screen which is probably easier. How to do this? I would think I would call the script with the OnTextChanged? And in the script use the .length property to see if it is 10? Maybe I just answered my question here!!

Why am I getting two records inserted into the table, when I'm expecting and needing one? The VB code below is checking whether the HTTP is secure or not, and if it is then execute the SPROC. But for whatever reason, I'm getting two records inserted about 5 seconds apart. Does anyone know why and how to fix? I just need one record.

Anyone know how to do this? I was thinking about making a sproc with something like
select * from users where @group not in member_of
select * from users where @group in member_of
Since I'm dead tired, that's not supposed to be a real query...just an approximation ;)

First I am using Entity Framework 3.5.
I have been listening volumes about this entity framework and though to have a dive in it. I got 3 tables and got the entities and model setup for my database, upto the point where I tried to execute sproc with the datacontext class. I added the sproc to Function Import but as Function Import does not support returning custom dataset that m sproc generates. I googled and found to create Complex Type, but here is the problem, "Get Column Information" in Add Function Import is disabled for me . why the heck its disabled, how to make this work and don't want to revert to older approach just that I could not execute sproc with EF.

In my project, I've been told to create a sproc to get some data. Fine. No problem. However, as we're moving away from a solution created by an external consultant I've had to spend a couple of days trying to figure out how the tables are linked. Sure... However, the big problem is that since this consultant is not supposed to know about this move just yet, I've been told to put my sproc in our production database (same server), and I've been unable to find any good info on this on google S

I want to keep the old password if the user leaves the password field blank, otherwise store the new password.
I have also tried "IS NOT NULL" instead of "= NULL", but without success. I've tried to send in an empty string and a DBNull value but it never keeps the old password.
