Databases :: SQL Connection Using C# / Install An Add To Cart Button?
Jul 25, 2010
I'm creating a shopping cart from scratch. I've created a catalog of various products and item detail pages which are linked to the database via a "SqlDataSource". Now I'm trying to install an add to cart button, and here's where I'm encountering problems...In the codebehind of the page I have the button event set up and working, it changes a label to say the item has been added. I add a MySQL connection using the namespace below:
[Code]....
Next I change the button event code to something similar to the following:
[Code]....
When I build it, it says that it can't locate the mysql namespaces and gives me an CS0246 error four times. The files who which it is referring are in the bin folder of the project and I have the files linked to the project via the web.config file.I thought maybe it just needs to be uploaded, but when I upload the files as is, the button doesn't do anything - the button will make the label display whatever was in the last successful build.
Implemented shopping cart overview with the ability to delete previous added items.Allows connection to Paypal
(I've already found http://stackoverflow.com/questions/1522832/looking-for-a-lightweight-asp-net-shopping-cart-that-is-paypal-compatible but the posted solution "shopping cart .net" does not seem to fulfill the third requirement, If I'm not mistaken.)
I am re-loading the Oracle 10g client on my .NET development machine. This Oracle client install is not the most intuitive and I just would like to know what the bare minimum client install is to run my ASP.NET project and what selection do I need to make at the beginning of the install process?
I have a webpage in which I an dynamically creating a button control for a shopping cart. The cart is made using HTMLTable. In the same procedure that builds the table, I create my button call "btnAddToCart". I have also added a "WithEvents" for this button in the page;
Here is the code pertaining to all references of the "btnAddToCart".
Code: WithEvents btnAddToCart as Button
Private Sub BuildCart() . . [Code]...
I'm actually loading a productID into the "ToolTip" property of the button. In the click event of the btnAddToCart, the code is not being executed when I set a breakpoint.
I did all the instructions which are in the following link: [URL] in order to do a connection between MySQL database and ASP.NET but I did not successed. Sometimes, it told me that I have a mistake in the <asp: button> and sometimes it told me that I did a mistake in calling (addImage) method. And this is my whole code:-
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="HW5._Default" %> <script> public class DataAccess { private string _strConn = @"Driver= {MySQLODBC 3.51 Driver};SERVER=localhost;DATABASE=test1;"; private OdbcConnection _objConn; public DataAccess() { this._objConn = new OdbcConnection(this._strConn); } // This function adds the Images to database public string addImage(timestamp id, byte [] data,string extension) { string strSql = "SELECT * FROM File"; DataSet ds = new DataSet("Image"); OdbcDataAdapter tempAP = new OdbcDataAdapter(strSql,this._objConn); OdbcCommandBuilder objCommand = new OdbcCommandBuilder(tempAP); tempAP.Fill(ds,"Table"); try { this._objConn.Open(); DataRow objNewRow = ds.Tables["Table"].NewRow(); objNewRow["Extension"] = extension; objNewRow["Data"] = buffer; objNewRow["ID"] = id; ds.Tables["Table"].Rows.Add(objNewRow); // trying to update the table to add the image tempAP.Update(ds,"Table"); }.....................................
I am currently working on the connection between ASP.NET and Oracle. I tried to search over the net and know there are many ways. Is there any 'normal practice' on which method to be used? Or it depends?

I am currently making a website on asp.net and i am creating methods using TableAdapter. I am connected to MySql using an ODBC connection. The select * from department will work perfectly for me but when trying to use parameters i am given an error message on the wizard. select * from department where name = @name gives me the error: Error in where clause near '@' unable to parse query text. also tried select * from department where name = ?: this gives me the error: No mapping exists from dbTypeObject to a known Odbc type.
I am connecting to Oracle database from .net using OLEDB.
My Connection string :
[Code]....
I am using above ConnectionString to communicate with database. To make it work, I have to store password (don't want to do that) in session and use it every time I need to talk to db.
1) Is there any other connection string without username and password with oledb?
2) I use "Integrated Security" for MSSQL. How can I use the same with OLEDB - Oracle database?
