c++ - how to design system so users can generate their own objects using dlls -

-

I have a server which takes some message X and winks some messages out. Currently y is mapping right from x. Therefore x1 will always generate y1 with related fields.

But now I want to be able to configure it so that users can put their own DLL which can generate x1 to y2, y3 or they want if they do not handle it Must take a default mapping that is x1 to y1

One more thing is that most of my output messages y1, y2, y3 are already objects that are all from the base class and I want to be able to do the same thing in another way Am ... meaning y2 (incoming message) is to be converted to user x1 on the basis of DLL. Can we get it using DLL? Or is there a better way of doing this ?? Is it a design pattern (factory pattern or something) to do it properly, so that it is also flexible in the future. Thanks!

It is not very difficult, but you must provide an interface header (.h file) DLL authors You will also need to tell them which compiler to use, or use a com-friendly interface.

A quick sketch will be an interface which is provided by

  • A query type supported function, DLL and to determine supported type Called by EXE
  • a std :: auto_ptr function.
  • Enter a virtual std :: string Ybase :: serialize () const function on the message in the text.

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 ;!

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
