Asp.net| Stored Procedures Recently met some friends in csdn to ask the method of the stored procedure on the ASP.net, here will my experience summed up and the release of processing for your reference. The basic idea is to get the parameters of the stored procedure, then collect the values based on the parameter table, and then call the stored procedure. However, the control ID required in the page must be consistent with the parameters of the stored procedure. And there are several ways to inv

ASP. NET -- Implement Dynamic Interaction between two drop-down boxes and asp.net drop-down boxes Introduction: We often encounter problems on webpages. First, select the province in the drop-down box. Then, the second drop-down box will automatically load the city in the province. This design greatly facilitates user search. How is this implemented? 1. Create a database "Province" table City table 2. Add controls 3. Bind data sources in the two drop-down boxes Protected void Page_Load (o

Configure the database connection string in WebConfig. The Code is as follows: Then obtain the connection string in Webform_1.aspx.cs and add the following reference; Using System.

See a post:SqlDataReader ShutdownEveryone seems confused about the link closure problem. Here we will explain it: No matter what xxDataReader is, It inherits the implementation of DataReader, so there are commonalities, so the title is titled DataReader. Case 1: The default link of DataReader is not closed. Sample Code:Static void Main (string [] args) { SqlConnection con = new SqlConnection ("server =.; database = MySpace; uid = sa; pwd = 123456 "); Con. Open (); SqlCommand com = new SqlComm
