Currently the web form web site is working perfectly.
In Web.config :
[Code]....
But, When i try to create a simple page by using the same DB connection in MVC, i get error message:
Exception Details: System.ArgumentException: Keyword not supported: 'driver'.Line 17: public SqlProductsRepository(string connectionString)Line 18: {Line 19: productsTable = (new DataContext(connectionString)).GetTable<Product>();Line 20: }Line 21:
[Code]....
In Controller:
[Code]....
i did add mysql.data.dll & mysql.web.dll to Reference.

I have built an ASP.NET classic application that references an ODBC connection to a DBISAM database.
When I try to connect to the same database in a MVC2 application I do not see any option to select an ODBC Data Source.
1. I right-click on my Models folder and select Add -> New Item
2. Choose "Data" on the left panel
3. Select ADO.NET Entity Data Model than click "Add"
Options were:
ADO.NET Entity Data Model
DataSet
LINQ to SQL Classes
SQL Server Database
XML File
XML Schema
XSLT File
4. Select "Generate from database..... click "Next"
5. Here I am presented with a "Choose Your Data Connection" screen. When I click the "New Connection" button I am given a "Choose Data Source" screen.
6. I am only presented with the following options on the "Choose Data Source" screen:
Microsoft SQL Server
Microsoft SQL Server Compact 3.5
Microsoft SQL Server Database File
<other>
7. This is where I expected to see ODBC as one of my options. What do I need to do to access ODBC?

my webserver is in the DMZ. The Database in the intranet. For connection from webserver to database the following entry is made in the odbc connection "TCPIP BCAST=NO;HOST=Intranet.Firma.local,Intranet_Spiegel.Firma.local,Intranet_Arbiter.Firma.local;PORT=2639}"
how to get this options in the connection strings working, or how i must modify the entitiy framework connection string to use the odbc entry?
<add name="KA_Entities" connectionString="metadata=res://*/Models.KA_Model.csdl|res://*/Models.KA_Model.ssdl|res://*/Models.KA_Model.msl;provider=iAnywhere.Data.SQLAnywhere;provider connection string="UserID=user;Password=password;DataSourceName=Databasename""
providerName="System.Data.EntityClient" />
<add name="KAPortal" connectionString="UserID=user;Password=password;DataSourceName=Databasename" providerName="iAnywhere.Data.SQLAnywhere" />
I tried to use odbcfor the entity framework, but the Wizard always add the right .NET Provider and not the odbc

I have been developing my ASP.NET web pages to access the SQL database locally on my personal computer while using a "SqlConnection", but to access my SQL database on a host server, I must use a "OdbcConnection". I am mostly using LINQ to access data with a DataClassesDataContext, but sometimes I must use ADO with SqlConnection and SqlCommand. What must I do to convert my C# code in order to access data with ODBC 3.51?

In my windows application, i am listing the System DSN's configured on the remote machine in a combobox. Once i select the DSN and click on Connect button, i should be able to connect to the remote database. I am trying to open the connection to the database using ODBC but am getting the below error.
ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified.
Below is the code sample
string conn = "Provider=MSDASQL;Remote Server=http://BLR1WKD010; Remote Provider=MSDASQL;DSN=" + clsODBC.pDBName + ";UID=" + txtUsername.Text + ";PWD=" + txtPassword.Text;
OdbcConnection odbcConn = new OdbcConnection(conn);
odbcConn.Open();

Seems like there are a lot of ways to solve this problem.
Currently I make a partial view with a form like so:

What are other ways to accomplish the same thing and what are the pros and cons vs what I am doing?
Is Ajax.Form useful?

I am working on an asp webform that pulls from an ODBC datasource then puts the data in an sql server. Once the data is in the sql server several queries pull data from it to provide information for a report.
This is an example of what I am talking about
private
void ODBCpdEmployeeAb()
{
DataTable dt =
new
DataTable();
[Code]....
The first part gets the data from the ODBC connection and the next part stores it in an sql server table. The problem is I have these methods in the page load event of the webform so everytime it loads it just puts the exact same data in the sql server table which would then provide incorrect information on the report.
Is there a way to append the most recent data from the ODBC table to the sql server ?

I'm using an ODBC connection to connect a SQL 2005 database to my ASP.NET app in Visual Web Developer Express. I'm finding that the expected functionality that tutorials review does not work for ODBC connected databases the same way as it does for SQL databases created in the Web Developer. For example, I can't use stored procedures because the option to create one is disabled in the Web Developer, and if I create the stored procedure in SQL Server Management Studio Express, it doesn't show up in Web Developer because Web Developer only finds the system stored procedures, not the user-defined ones. I've seen other cases as well where database management options in Web Developer don't work with ODBC databases.
Am I missing something in my setup, or is there an inherent limitation with ODBC connected databases? Or, is this a limitation with using the Express versions of these development tools?

OK, I'm sorry if the tile of the question was unclear, and if you understand what I mean, please don't hesitate to help me think of a better one.
Anyway, I have a <input type="submit"> element for my form, and I want it to return the same URL as the URL of the page the element is on.
Currently, if I click the button, it takes me from /Calculate/Quadratic to /Calculate/QuadraticForm
In my controller for this view, I have the following code:
[AcceptVerbs(HttpVerbs.Get)]
public ViewResult Quadratic()
{
ViewData["Root1"] = "";
ViewData["Root2"] = "";
return View();
}
[AcceptVerbs(HttpVerbs.Post)]
public ViewResult Quadratic(QuadCalc boss)
{
ViewData["Root1"] = x1;
ViewData["Root2"] = x2;
return View();
}
And here is the markup and code for my Quadratic view page, which includes the form which includes the submit button I've been referring to:
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<h2>Quadratic</h2>
<% using(Html.BeginForm("QuadraticForm", "Calculate")) %>
<% { %>
<div>
a: <%= Html.TextBox("quadraticAValue") %>
<br />
b: <%= Html.TextBox("quadraticBValue") %>
<br />
c: <%= Html.TextBox("quadraticCValue") %>
<br />
<input type="submit" id="quadraticSubmitButton" value="Calculate!" />
<br />
<p><%= ViewData["Root1"] %></p>
<p><%= ViewData["Root2"] %></p>
</div>
<% } %>
</asp:Content>
Therefore, all I really want is to have the submit button return the same page, but the HTTP post will aid the application in passing new ViewData. Unless I'm interpreting this all wrong.

A web application works with the database. Once a day, the database should be scanned and alerts should be sent to users. From what I've seen out there, additional project has to be created which will be installed on the server and will work with the same database. Executable created by this project has to be installed in Windows scheduler to be activated once a day.This seems complicated and inefficient: starting additional executable and working on the same database.

I am working in a school and we recently installed a new server running WinServer 2008R2. I want to be able to point people to a URL on our intranet and have them fill out a simple registration form and have this data written to a database. It would also be nice to have some data auto-populate (such as their name).
Is it overkill to set up a sharepoint server and try to do this with Access Webforms? Could I use something like dotnetnuke and find a module that works? Or how about options for writing custom forms?

My code is to update a record if it already exists in database else insert as a new record. My code is as follows:
protected void Button3_Click(object sender, EventArgs e)
{
OdbcConnection MyConnection = new OdbcConnection("Driver={MySQL ODBC 3.51 Driver};Server=localhost;Database=testcase;User=root;Password=root;Option=3;");
MyConnection.Open();
String MyString = "select fil_no,orderdate from temp_save where fil_no=? and orderdate=?";
OdbcCommand MyCmd = new OdbcCommand(MyString, MyConnection);
MyCmd.Parameters.AddWithValue("", HiddenField4.Value);
MyCmd.Parameters.AddWithValue("", TextBox3.Text);
using (OdbcDataReader MyReader4 = MyCmd.ExecuteReader())
{
//**
if (MyReader4.Read())
{
String MyString1 = "UPDATE temp_save SET order=? where fil_no=? AND orderdate=?";
OdbcCommand MyCmd1 = new OdbcCommand(MyString1, MyConnection);
MyCmd1.Parameters.AddWithValue("", Editor1.Content.ToString());
MyCmd1.Parameters.AddWithValue("", HiddenField1.Value);
MyCmd1.Parameters.AddWithValue("", TextBox3.Text);
MyCmd1.ExecuteNonQuery();
}
else
{
// set the SQL string
String strSQL = "INSERT INTO temp_save (fil_no,order,orderdate) " +
"VALUES (?,?,?)";
// Create the Command and set its properties
OdbcCommand objCmd = new OdbcCommand(strSQL, MyConnection);
objCmd.Parameters.AddWithValue("", HiddenField4.Value);
objCmd.Parameters.AddWithValue("", Editor1.Content.ToString());
objCmd.Parameters.AddWithValue("", TextBox3.Text);
// execute the command
objCmd.ExecuteNonQuery();
}
}
}
I am getting the error as: ERROR [42000] [MySQL][ODBC 3.51 Driver][mysqld-5.1.51-community]You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'order,orderdate) VALUES ('04050040272009',' &' at line 1
The datatype for fields in table temp_save are:
fil_no-->INT(15)( to store a 15 digit number)
order-->LONGTEXT(to store contents from HTMLEditor(ajax control))
orderdate-->DATE(to store date)

This code works only in HTML format. This means that I can not select standard components: "Inserting an ASP.NET control will convert the HTML form in the page to an ASP.NET form and remove its current properties. Do you want to insert the ASP.NET control?"
When converted following code does not work anymore. I'd like that code works in ASP.NET mode.

I've created an application using ASP.NET with Access DB, now I found somee.com who support only SQL Server DBs, so Now I must convert my Access DB to SQL Server DB.
Is there any tool who can do the trick ?
This is some code I'm using in my web application :
Public Shared Function conecter() As OleDbConnection
Dim MyConnexion As OleDbConnection = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data source=" & System.AppDomain.CurrentDomain.BaseDirectory & "/Learning.mdb")
MyConnexion.Open()
Return MyConnexion
End Function
Public Shared Function lecture(ByVal requete As String) As OleDbDataReader
Dim Mycommand As OleDbCommand = conecter().CreateCommand()
Mycommand.CommandText = requete
Dim myReader As OleDbDataReader = Mycommand.ExecuteReader()
Return myReader
End Function
In this case, If I convert my database I must change the OleDbConnexion and other things or I can just leave them like that ?
