I'm having some issues trying to create and setup a database to use for a project. I have SQLExpress running in the background, but I figure that's from my old Visual Web Developer 2008 Express. I have MS SQL Server 2008, but it doesn't look like it's installed. I'm guessing I need to manually install it before trying to add databases/tables.

I'm trying to create a stopwatch in asp.net that displays the time in seconds as the text of a label. But I noticed that the timer control in asp.net only refreshes the whole page at each tick interval. I managed to create a clock in VB.net using the following code:

i'm trying to create a stacked bar chart on a vb web form using vs2010.My data source returns:
Error in Functionality Awaiting on Supplier

IMT Issues,Awaiting on Supplier
2,IMT Issues,Awaiting on User 4
IMT Issues Closed 120
Login / Password Active
But I can't get this into a stacked chart. I know I must have to do quite a bit of work declaring what the series are and soforth, or having a different dataset but can't find any documentation on it.A link to some documentation or an example of a stacked chart from an sql datasource would be much appreciated.
Someone can explain this error?Error Creating Control - headObject reference not set to an instance of an object.
<%@ Page Title="" Language="C#" MasterPageFile="~/Controls/Master1.Master"
AutoEventWireup="true" CodeBehind="GrupoUsuario.aspx.cs" Inherits="GrupoUsuario" %>
<asp:Content ID="Content1" runat="server" contentplaceholderid="head">
</asp:Content>
I Think this is a bug of visual studio 2010 in design view. I'not using any event to manipulate session object in the method OnInt(). The "PlaceHolderTopo" is an placeholder in the web user control Topo.ascx. It's work normaly. I Don't have any code inside the content place holder in the page tha inherits from the master page and get this error.Below is the code of the masterpage:

I get the following error which I don't get when I build a simple WCF Data Service in an non MVC project. I added the following to my global.asax:

The type 'MvcWebApp.WcfDataServiceTwitter', provided as the Service attribute value in the ServiceHost directive, or provided in the configuration element system.serviceModel/serviceHostingEnvironment/serviceActivations could not be found.
I am new with SSIS, what I need is to search on a specific column in a table.
I am using asp.net with C#, and I dont have a cluw how to start and implement this.
I can't believe I'm having so much trouble finding this information. I'm endeavouring to learn about creating model classes with Linq to SQL. By default VS2010 wants to use SQL Express, but our organisation has several database servers for development so I'd rather use one of those. PLEASE can somebody tell me how I can configure VS2010 to do that, as all I get is 'A network-related or instance-specific error occurred while establishing a connection to SQL Server ... Verify that the instance name is correct'. Yeah, thanks Microsoft. Actually telling me how to verify the instance name would be a really good move here.

Am trying to get a working enity model with foreign keys working but have run into a problem. I have imported 3 tables with content and some data.Lets call these tables geo_countries, geo_counties, geo_municipalities and the FK are:1. geo_county have a column country_id wich corresponds to country_id in geo_country 2. geo_municipality have a column county_id wich correspond to the county_id in geo_county.The problem i have is when i try to get correspondig child items with the following code i run into trouble:
[Code]....
The problem above is that 'test' generates results but not 'test2', wich never return anything. Am i not supposed to be able to do it like i do in 'test2'? I earlier tried to add a child object by replacing ToList() with Add() and that worked. But i cant seem to get anything out of it.
Never really worked with the asp tables but for this project it makes more sense, I am having trouble addding rows dynamically from the sql datatable i am pulling. In hte datatable it has 12 rows with 14 columns, I need to make this into a table, with a dtagrid I would be done but I have to pull other data that they could add columns, so a table I am told is easier.
This gets my data and I can see it
mydataTable = new DataTable
mydataTable = GetData(sql)
mydataTable.add.row(myDataTable.rows(0)(0))
I get nothing but errors trying to do this, what is the correct way to add rows to an asp.net table
Can I add this all to a datagrid and then add the extra columns I need if they are there with out using a table.
i already followed steps in msdn and created a new

I have a dataset with 3 tables that are inner joined. Thsi dataset is connected to an object datasource which is connected to a gridview. So at runtime it displays data from the database. The problem is when I click on a save button to add information to the database it throughs me an error saying Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints. But if i have two tables in my dataset it works 100%. But the problem i need that 3 tables in order to pull the required information. And if i populate the gridview using code to select the information from the database and insert information it also works 100%.

View 5 RepliesI've got a MS SQL (Express) database. its quite complex and uses a lot of tables. Is there a way to generate a SQL script for creating the complete database, but not the content of it.
I like to copy the database. Right now i copy the database. After that i need manually to clear all fields. There are also some relationships, so its a lot of work to clear all of it manually.
If I have a DataTable (in-memory) read by my C# program from a flat file, and I want to create it as a new table in a SQL Server database... what is the simplest way to do that?
It seems like something like SqlBulkCopy with an option to create a new destination SQL server table would be on my line of thinking, but I dont see a way.
Ok, I have some experience, but I have always started with something and moved on from there.
I want to create a ASP.net Project in MSVC 2008 with the following...
- SQL 2005 database that I can use MSQL Server Management Studio with
- Forms authentication
- Authentication/roles etc is stored in the above database
So far every attempt has resulted in a database that when I attach with MSQL Management Studio I am logged in as guest, and thus can't do much.
I've inherited a SQL Server 2005 table where there are several colums of the image datatype. I'd like to extract all of those images and save them as files to a folder. How can I do this using VB.NET?

In visual studio 2005 for windows application , there is option where you can add New datasource by going to menu Data>Add New Data source, I know you can connect to database by using Dim con as connection, Dim cmd as command, Dim da as ataadapter, then query database and get result

I'm using VS 2008 and SQL 2008.
I have created the tables and the stored procedures in SQL 2008.
In VS 2008, I created DataSet1.xsd in App_Code and created the connectionString in web.config file.
Then when I go into the DataSet1.xsd and try to add a TableAdapter, strange things happened.
First I chose the data connection, then selected "Use existing stored procedure", then there was nothing listed in the dropdownlists (in Select, Insert, Update, or Delete).
I'm sure the connectionString is correct because if I choose "Use SQL statement" and type in a "select * from mytable1", the TableAdapter can be created without any problem.

Well I'm not familiar with SP's yet, and I can't find a single example of what I want to do. basically I want to retrieve the town & county where the customers id are equal (note there will only ever be 1 result)

I can't insert Ajax controls in VS2010. I installed the latest release of Ajax and have tried to use several ajax controls. In particular I tried to insert a combobox control and I get nothing. I removed Ajax and reinstalled and I get the same problem.I have installed ajax twice. I am an expereinced ajax user. Is there something else I need to install in VS2010 to get Ajax to work?
View 6 RepliesI've just started working on some test asp.net webforms projects and am having a problem with VS2010. It is not displaying any controls at design-time. For every control I'm getting message -
Error Creating Control - xxxxx
Object reference not set to an instance of an object
It is doing it on new web.application and Tailspin Spyworks demo app. If I switch a new web.app from asp.net4 to asp.net3.5, all the controls display properly.
I've tried removing and re-installing VS2010 and had no changes.
It acts like something didn't get installed.
I am using VS 2010, just downloaded the Ajax Control Toolkit Binaries, have got not wireless mouse (even I tried to unplug my mouse - no success -) and I have tried deleting the .tbd files as mentioned
here; but still the Ajax control toolkit controls are grayed out and disabled!
I have tried the following also:
1. creating a new webite.
2. changing the target .NET framework from 4.0 to 3.5 and vice versa.
3. Restarting VS and Windows.
