Apr 29, 2011
Tools for my website.Visual Studio 2010SQL Management Studioasp.netvisual basic.netI am using GridView. Because of my search code I am not able to use the automatic delete function that GridView has to offer.I clicked on GridView, said "Add New Column" and added a checkbox column.I want to be able to check one or more boxes and select a button that will delete those rows from the database using a stored procedure.

i have a gridview, linked to a sqldatasource. I have added a stored procedure to delete from multiple tables, and then enabled deleting on the gridviews smart tag.
When i click the delete button i get an error message, "Object must implement IConvertible". I read that it is a problem passing the parameter to the stored procedure, possibly the wrong datatype being passed. Im not sure if i am passing the parameter to the stored procedure at all. The parameter should be the gridviews datakeyname, in this case it is "UserId".
The stored procedure works i fine in management studio, so i think it is just the parameter being passed (or possibly not being passed)
Do i have to code the parameter in the code behind to be passed to the stored procedure?
<asp:SqlDataSource ID="selectUsers" runat="server" ConnectionString="<%$ ConnectionStrings:CASSFConnectionString %>"
SelectCommand="SELECT aspnet_Membership.UserId, aspnet_Membership.IsLockedOut, aspnet_Membership.Email, aspnet_Membership.CreateDate,

I already know how to call insert, update, delete & select procedures in DataSet.xsd window. And I also know how to call queries by table adapters. But I just found out that its not possible to call all functions by queries (such as insert). It works when I test the query but when I try to add it, it says "Failed to get schema for this query". So I built a few stored procedures which do many functions (such as transaction, insert, update etc...). But I am unable to use these stored procedures in VB form. I found some tutorials mentioning that it can be done by defining connections and some other stuffs with which I don't want this to be. I want to call these procedures by writing code in VB code editor window with DataSets, TableAdapters, BindingSource etc...

So I have an application that saves and retrieves images from an Access database. The images are displayed in a picturebox but I'm having a bad time figuring out how can I move to the next/previous record/image in the database, so the user can view them and delete it if he wants to...
Here is a screen of my form so you can better understand what I'm trying to do:
And here is the
Imports System.Data.OleDb
Public Class Form1
Dim dbConnection As New OleDbConnection

Save and delete functions work fine, I just need to know how to do the Next and Previous buttons... This should be easy to do, but I'm still a beginner to VB
Biggest problem is that this is a part of a school work which I must deliver tomorrow.

I have created Stored Procedure in server explorer, and added this to my Form1
however, I find out I cannot simply use QueriesTable.Adapter.StoredProcedure1 in my VB code but I can add this Stored Procedure from TableAdapter and use TblContactTableAdapter.StoredProcedure1 to use this procedure, but I think it's kinda fool, why can't I use it directly from QueriesTableAdapter?
And I would like to know:
I think it's good to make stored procedure in database design so this procedure is saved in database server, rather than Client Side Application
Also, are queries created from TableAdapter saved in Client Side Application? which is not saved in database server side?

I've seen posts on deleting the lines from a text file that are specified as a function parameter, but I only need to delete the first and last lines from the file.
I'm still a newbie when it comes to working in files, but it seems that it should be simple to delete the first line... Just delete all text from BOF to the first CrLf character. Am I right?
As for the last line, I understand that I'll have to get a count of the lines in the text file to find it (as the file won't always be x amount of lines long).

I'm wanting to encrypt some data (hopefully under five hundred bytes' worth) and store it in a QR code. Originally I wanted to use RSA, so the data would be signed with User A's private key and User B's public key, but unfortunately, VB.NET doesn't like encrypting that much data. I've read that I should use Rjindael to encrypt the actual data, and then use RSA to encrypt the key used by Rjindael. However, I'm not having much luck being able to search the web for some kind of tutorial or something.
Also, if I was wanting to store this on a QR code, wouldn't I have to store both the encrypted data and the encrypted key used by Rjindael? Do you think this would all fit? I may be able to use version 40 on medium error correction [URl].. it stores 18,672 "data bits"), but I would prefer to use a lower version (that is, smaller) if at all possible.Generating the QR code won't be the problem (I know there's a .NET library for that), I'm just curious about getting the data encrypted to begin with.

Some question about Ado.net and SQL Server stored procedures. We have a stored procedure in SQL Server as described below

we are using vb.net in visual studio 2003. Now if ExecuteNonQuery is used then we do not get rows. If ExecuteReader is used then we get rows [ with forward-only access which is of no use to us] but we cannot get output parameters values returned by stored procedure?

calling stored procedures using ADO.NET. We have an application developed, which uses SQL Sever as backend and Visual foxpro as front end. In this application every thing is done by database only. That is all insert, update, delete operations are done by SQL Server only. So we have to provide some input and output paramaters to stored procedures. Some time these procedure carry out insert, update, delete operations as well as return some data in the form of tables.

I want to call a Stored Procedure using SqlDataSource. I've been reading the library documentation of the classes but i'm getting slightly confused. To call a stored procedure, I understand that I have to change the selectcommandtype and then set the selectcommand property to the name of the procedure.
'Change command type to stored procedure
SqlDataSource1.SelectCommandType = SqlDataSourceCommandType.StoredProcedure
'set name of stored procedure

For some reason my stored procedures are all executing twice! I have a static function that runs an SP given its name and the parameters and fills a datatable.
Public Shared Function RunSP(ByVal spName As String, ByRef spParams As Dictionary(Of String, String), ByRef pDataTable As DataTable) As Integer
Dim cmd As New SqlCommand
Dim lAdapter As SqlDataAdapter
[code]....
Is there something wrong with the code? I've checked with the debugger and the appropriate SPs are definitely only being called once, i.e. this function only runs once for a particular insertion function, but two things are inserted into the table.

I am trying to use stored procedures with LINQ to SQL to perform insert, update, and delete operations. My update and delete procedures implement optimistic concurrency by checking the original values retrieved from the database with the current values in the database. A row count is returned to indicate if the row was updated. When I execute SubmitChanges on the data context to update the database, everything works fine except that the generated code doesn't check for concurrency. (I configured the insert, update, and delete operations to use the data context methods created from the stored procedures using the O/R Designer, and I assigned the original object properties to the method arguments.) I can customize the generated code so it works properly, but I know that I shouldn't do that because I'll lose the changes if the code is regenerated. I also know that I can add a partial class to extend the data context, but I don't know how to implement the methods correctly. All I really need to do is to have the methods return the row count, but, of course, that's not an acceptable method overload. I know that I can also call the methods directly rather than calling SubmitChanges, but it seems like this is intended to work with SubmitChanges.

I'm building an c# app that is designed to replicate and enhance the functionality of an VB6 app developed many years ago. My problem is that one module in the old app does some realy complicated things and trying to replicate this starting from specs would be a big pain for me. Even if this sounds like the best idea.
My question is : is there a way i could keep the old VB module and integrate it into the c# app, so that i wouldn't have to rewrite everything ?

I have the following query:
I have 3 stored procedures that give me information to generate the menu of a website, which are:
1st procedure (call it sp_menu)
This procedure generates timely information on a menu (can be more than one)
The 2nd procedure (call it sp_submenu)
This procedure generates information on the submenu of this menu (can be more than one)
3rd Procedure (I'll call sp_item)
This procedure generates information on the sub-menu items (may be more than one)
How I can do to automatically generate the ASP.net menu with the information you give?
The information delivery process is similar to this:
sp_menu
MENU_ID --- MENU_NAME --- MENU_ORDER
1 --- Menú 1 --- 1
[Code]....
The menu is ul (unordered list), the submenu are li (list item) and item are ul (unordered list)
How do I get ASP.NET with VB (. NET 4.0) the order automatically?

I noticed in the Entity Framework designer that you can map stored procedures for Insert, Update, and Delete operations. Is there any way to do this for Select operations as well, or is there a new direction for database access code where we don't really write stored procedures for our basic select operations any more?The company I work for is pretty adamant about always using stored procedures for every database operation, even though the Entity Framework makes the calls safe by calling sp_executesql.It seems like both LINQ to SQL and Entity Framework have moved away from using stored procedures for selecting the data. Is this an accurate statement?Just to clarify my question:I have a table in my database called Product. I use the wizard in the Entity Framework to generate my models...so I now have an Entity called Product. When I do the following query:
db.Products.SingleOrDefault(p => p.Id == 1);
It generates code similar to:
EXEC sp_executesql N'SELECT * FROM Product'[code].....
If it's not possible to do that using SingleOrDefault I'm fine with that. I'd much rather have the following:
db.Products.GetProduct(1);
Is this something that is normally done or do most people just have it dynamically generate the SQL?

I'm creating a database installer where I have some code to create database, tables, stored procedures, etc.I don't have problems when creating the database, tables and inserting required data. My problem is when my code gets to the stored procedures section.
Here is what I do:I have different text files (database.txt, tables.txt, insertdata.txt, storeprocedures.txt) where my sql syntax is located.I execute every process/text file using the following:
ExecuteSql("master", GetSql("database.txt")) ' Creating 1 database.
ExecuteSql("mynewdatabase", GetSql("tables.txt")) ' Creating 15 tables.
ExecuteSql("mynewdatabase", GetSql("insertdata.txt")) ' Inserting data to many tables.
ExecuteSql("mynewdatabase", GetSql("storeprocedures.txt")) ' Creating 6 stored procedures.
Here is part of the error:In exception handler: Incorrect syntax near the keyword 'PROCEDURE'. "This is the second stored procedure because the variables I get below belong to the second one"
Must declare the scalar variable "@intVariable1".
Must declare the scalar variable "@intVariable1".
Must declare the scalar variable "@intVariable1".
Must declare the scalar variable "@intVariable1".
When trying to create 6 or even 2 stored procedures using the same file 'storeprocedures.txt' is not possible. If I leave just 1 it works but I really want to keep them together.
Creating 15 tables using the same file 'tables.txt' works, inserting data in different tables using the same file 'insertdata.txt' works.This is the general syntax I use:
Create Procedure sp_stored1
@intVariablex int

[code].....
Is is possible to create more than 1 stored procedure the way I'm trying to?Do I need to end every stored procedure with specific sql syntax, other than the 'end'?
