sql server - Where/How do I handle different connection types using Repository Pattern with ADO.Net? -

-

I'm new to the repository pattern, but building a repository to connect to two different database types I have those who have the same data structure.

  1. I will be connected to SQL Server 2005 and db2 (on iSeries)

    / li>

  2. I am using the repository in a WPF application.
  3. Although I want to use the unit framework, I can not. That's because IBM has imposed a good charge of $ 11,000 for a product called DB2 Connect, which will then give me access to my datacontext. Due to budget constraints, I am using ADOnate and using IDBCX interface.
  4. Why am I using two separate databases 1) Political, 2) Because our ERP system is based on AS-400 is very limited so I have to download my data to SQL Server and 3 ) Political

I have discussed all the tutorials on opening the connection within the call to the GetRecords () method. However, it is limiting me to a database.

  1. So, should I pass my connection object into my GetRecords method ?: GetRecords (MyIDbConnection)? It seems to restrict me if I decide to use XML (for whatever reason.)

  2. Within my GetRecords method, call me from the app needed. To get config connection string? Will this limit me if this repository is compiled in a .dll that does not have any app? Configure?

  3. Should I give a connection through Constructor instead?

  4. Can I use a data adapter?

Please advise.

Thank you.

You can use the pattern to provide a general way for the repository to be combined with the repository pattern You may want to consider communicating with the Data Access Layer. The gateway will provide a standard, platform-agnostic interface that does not require a repository to know something about the data source and its related APIs. You can present an example of a gateway in your repository using the Data Framework. This will help you control which types of gateways are transported through the repository of your central contents through the configuration strategy.

asp.net - Javascript/DOM Why is does my form not support submit()? -

This is my first time working with asp.net and javascript, so I do not know very good web resources, or Much about javascript debugging I have to find out that on line oFormObject.submit (); Microsoft JScript Runtime Error: Object does not support this property or method I am using the link to work as a button because I am terrible in aesthetics and I think That link will look more professional than a table of 50 buttons. I have read that this solution can cause problems with browsers due to pre-rendering of my links and many additional traffic and problems, but CSS gives me a button like a link, which has issues of alignment and difference seemed to. & lt ;!

sockets - Delphi: TTcpServer, connection reset when reading -

I am trying to implement one for Delphi, but there are some problems with communication. Fitnesse will start my process, and give me a portmember as a command line argument. Then I should make a socket on the port number given to me, and fitness will connect to that port I am using a TCPCP server for the job: < Pre> TcpServer1.LocalPort: = ParamStr (ParamCount); TcpServer1 Active: = true; On OnEXEPT () -Event, I send the protocol version to use as specified in the protocol. Process TForm1.TcpServer1Accept (From: TOBject; ClientSocket: TCustomIpClient); Var s: ansistring; Start clientSocket. Syndrome ('slim - v 0.0', # 10); SetLength (S, 6); ClientSketts Receavebook (S, 6); End; When I call ReceiveBuf (), the process ends, and fitness throws an exception: java.net.SocketException: connection Reset I have seen what sent and received. It shows that my code sends the protocol version, fitness sends back a message, and when I try to get this message

javascript - Classic ASP "ExecuteGlobal" statement acting differently on two servers -

-
I have a strange problem that I really do not know. In addition to developing a new ASP.NET site, I have to support the old "classic ASP" site. It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP. The problem is that some Javascript functions are running "OK" on the production server, but when they use it as a server, they are not defined on my PC what is happening that last Programmer, for some reason, has decided to put some functions in a series of files, which according to the observations, imitate the "need_once
