I've got a stored procedure that right now generates a gridview. From that gridview, users want to be able to click on a button, and export it to Excel, where they can manipulate etc locally.But I used this
Dim sw As System.IO.StringWriter = New System.IO.StringWriter
Dim hw As System.Web.UI.HtmlTextWriter = New HtmlTextWriter(sw)
gv.RenderControl(hw)
Response.Write(sw.ToString)
Response.End()
and from that I get a message every time it goes to excel,"The file you are trying to open,'Defauly.xls', is in a different format than specified by the file extension. Verify that file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?" Users don't want that message.. but I can't find any way of getting rid of it.any solutions that does not involve tinkering with system registries (it's not feasible for this project)?
My other option is to convert the gridview to a datatable, and have another process do the export. But I'm stuck on the part where I dynamically create the columns and column names from the gridview (or stored proc for that matter).. . it won't always be the same amount of columns etc, so I can't hard code that in.
I am trying to execute a stored procedure and place the information in a datagrid(without using the .net wizard) i want to do it manually. Using ado.net i believe. I am using vb.net and asp.net
Public cmd As New SqlCommand() Public saoda As New SqlDataAdapter(cmd) Public conn As New SqlConnection(" ") Dim saods As New DataSet
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?
I have two GridViews, the first works fine as I defined the datasource when I dropped it onto the asp page via visual studio and I specified the table to use.
The other GridView (dgvParams below) has just been dropped onto the asp page and I want to use it at run time[code]...
When I step through the code I can see row and column counts are as expected and call "dgvParams.DataSource = table".
I have the following code in my asp page: Imports System.Data.SqlClient Imports System.Data Partial Class _Default Inherits System.Web.UI.Page [Code] .....
And while the page doesn't throw me any errors, I'm also not seeing any data in my datatable.
I have an Excel workbook which I created a sub-routine to insert data from the selected worksheets to a Sql database with the Sql stored procedure. I tested the sp using the Sql Management Studio and it works fine. However when I tried to call that store procedure and it failed. [Code]
I found a few examples online on how to import excel into sql via vb. but can i do it via stored procedure? Insert into SQLServerTable Select * FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0', 'Excel 8.0;Database=D: esting.xls;HDR=YES', 'SELECT * FROM [SheetName$]')
So like, can I pass in: ('Microsoft.Jet.OLEDB.4.0', 'Excel 8.0;Database=D: esting.xls;HDR=YES', 'SELECT * FROM [SheetName$]') As a parameter to SQL Server SP?
Now i am using below code for excel generate from gridview but now its not working because i have added Dropdown checkbox and textbox inside the gridview..
code for export gridview into excel with dropdown, checkbox and textbox values...
Protected Sub Button_ExportDataInExcel_Final_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button_ExportDataInExcel_Final.Click Response.Clear()
I have a stored procedure to update a table, but needs a couple of values from another table.
the first two selects get the value from the table and then are used in the update statement.
The select statments:
Select @iStatusDropDownValueID = iDropDownValueID From DropDownValue Inner Join DropDownValueType On DropDownValue.iDropDownValueTypeID =
[Code].....
First, the values that are retrieved by the first two select statements are always the same. So they could be passed in by the code itself. I don't know that this will speed things up at all, just make the entire stored procedure better and easier to read.
Second, if the "Value Name" should change this store procedure will break (which is possible, but not often).
I am looking for any insight into the Best Practices for this situation.
I want use a stored procedure in my project but I have no idea about it. Please could you tell me a little bit about how to use I can use one in my vb.net application ?
I have noticed the following but unable to understand why.Whenever a procedure is called in .net it takes more time than when it is called subsequently.Even if a procedure is called after some interval it takes more time than it takes if it is called quite frequently. i am not asking about sql query or sql command. any user definded function or user defined method takes much more time to finish when it is called occasionaly. but when the same procedure is called quite often it finishes a lot faster. why?
I am currently building an ASPX webpage for internal use. Basically, there are two buttons on this page and I need each one to kick off a different stored procedure on our local SQLServer based on the needed task. these stored rocedures do quite a bit of work and take 3-5 minutes to finish running. In neither case do I need any kind of gridview or other output from these stored procedures, as they are simply crunching/cleaning data that will populate some tables that the user will then use to complete their task. There are also no inputs or parameters needed.
So i'm OK at ASPX and pretty good at SQL, but have no idea on the VB code behind page. This is what I have ben able to put together based on 3 days of googling. i think i am close but can't quite get across the line.
CODE:
I'm not sure if you need to see any of my ASPX or my SQL. both work fine on their own, but i am not able to get these buttons to work.
I have a stored procedure that when I run it within my application it times out, but when I use Management Studio and pass in the same exact parameters, the stored procedure executes under a second. I had this exact same issue with the same stored procedure before, and all I did was recompile it, and it fixed the problem, but I do not want to keep having to recompile this stored procedure every few days or so. Has anyone else ran into this issue before?
Another note I would like to mention, is that I'm currently working on a test database, so I'm not inserting, deleting or updating any of the records that the Stored Procedure is using. So the database itself is not changing, but for some reason the Stored Procedure is showing degradation, and at the most we have 2 users in the database at a time.
Below is the code I use to call the Stored Procedure from my app.
As I mentioned, if I run the Stored Procedure within Mangement Studio, it runs with no problems. Also if I recompile the stored procedure, it runs fine within the app, but after a few days, the stored procedure starts to timeout again within the app and I need to recompile it again.
I am pretty new to VB and I am not sure why this is not working, basically I am trying to run a stored procedure from my web code. The sp runs just fine in SQL, I've tried it several times so I am sure that is not the problem. I don't want to return any results, I just want to see an "ok" statement if it runs and an error message if it doesn't. The code I am using for the lables (warnings and confirmation) is reused from earlier on the same page, the same goes for the validations (valUpload).
I am using SSMS 2008 and VB. I'm a novice VB developer. I am trying to display results of a simple stored proc on my ASPX page. But I get the error below. Here is my code behind for the ASPX page:
I am trying to get some data relevant to a stored procedure (or funtion) back from a database using .Net. The first thing I need to be able to do, is get the stored proc from the database and turn it into string format.The information I need is: The return set of columns, tables used within the SP, Stored Procedures called from the SP. The only way of doing this at the moment that i can think of, is though parsing the text and looking for keyword matches.
I am a newbie to vb.net and sql server. My responsibility is to build a vb.net function that when a scanner scans an object, it would take the scanned string and call a stored procedure to get a row of data that match that scanned string and pass the data row to an application that would print out a label.below is my vb.net and sql server stored procedure script
1. Do I have to come up with a public class in order to store my row of data to pass it on to a different vb.net application that would take that data row and print out a label?
2. In my stored procedure, how would I return the founded data row to the vb.net function?
Module makeLabel Public Class AMGCdata Public fileName As String[code]...........
Why I can NOT get the return value (Scope_Identity) by executing my own Stored procedure (SQL Server 2008) via this below code written in VB.NET 2008? The SP inserts the new record into Table1 but I have 0 as the return value!What's wrong with it?here is my vb.net code and my SP:
Public Function Insert(ByVal Obj As entity, connectionString As String) As Integer Dim ScopeIdentity As Integer Dim Connection As New SqlConnection(connectionString)
Where in the body of a function do you code a stored proceedure? Does the storeProceedure "spInsertVendor" replace the sql commands? Here is my code:
Private Function AddVendor(ByVal vendor As Vendor) As Integer Implements VendorService.AddVendor Dim connection As SqlConnection = PayablesConnectionFactory.GetConnection Dim insertStatement As String _ = "INSERT Vendors " _
I'm having problems trying to create a new stored procedure.I am using sql 2005 express. I also have sql server management studio express installed.I open up the studio express and goto the database that i want to use to create the stored procedure. When I right click i see a sub menu, but don't see a option that says create stored procedure ( or any option that has anything to do with stored procedures ).Am I right in saying that I need the full version of visual studio to be able to work with and create new stored procedures.I am also told that sql server comes with built in stored procedures. Am i right in assuming that I can call these without having visual studio installed. And if the answer is yes, then how do I find out the name of these procedures, the parameters they use and what each particular stored procedure does.
Dim parm1 As New SqlClient.SqlParameter("@Category_ID", txtCategory_ID.Text) Dim parm2 As New SqlClient.SqlParameter("@Category", txtCategory.Text) Dim parm3 As New SqlClient.SqlParameter("@Area_Name", txtAreaName.Text) Dim cmd As New SqlClient.SqlCommand cmd.CommandText = "dbo.udp_tblArea_ups"

i am using this code to insert data into my new table using a stored procedure now i want to delete data from the table using a delete stored procedure.
I've added few stored procedures to my SQL Server 2005 database. Few of them were a procedures containing SELECT statements and one of them contains INSERT statement. While executing the procedures with select statements are as easy as displying tables, the procedure with INSERT statement is not so easy [for me].At first, i've tried to add the procedure to the dataset and execute it as others, by filling the table adapter. But... there is now way to access the tableadapter within the code... VB does not recognise it! Just like it wasn't there! It's not even listed on with the other tableadapters below my project. It's viible only in the dataset!After few minutes i've removed the procedure from the dataset and tried to add it as a query. Everything seemed to be ok... but... after naming a function, that would execute the query.... the function is visible nowhere. I can't execute it within the code.
I have a stored procedure in SQL Server for generating transaction numbers.how to call the Stored Procedure from VB.NET and how will i get the value that is returned from the procedure into the front end.
