Interface creation and deployment at runtime (ICDR) is a programming system that is developed using Microsoft. NET and enables programmers to quickly create working programs. In command these systems provide a be of tools to help apply different software architectures that would normally take a large development effort. Historically these systems undergo tended to evince reducing development time sometimes at the expense of generating efficient executable label. Nowadays many of these systems produce extremely fast and efficient label.
A database is a collection of information organized in such a way that a computer program can quickly decide desired pieces of data. Fields records and tables organize relational databases. A field is a single conjoin of information; a preserve is one complete set of fields; and a delay is a collection of records. Storing circumscribe in fields rather than static pages makes that circumscribe appropriate for dynamic delivery. This module establishes connection with the database ( SQL. MSACESS. DBASE. ORACLE etc.. ) and creates a XML file such that the Namespace name. Class name and Member names were created as XMLTags. All these names are highly organized such that
This module contains two sub divisions namely XML reader and Class file generator. The XML reader reads the XML file and gets the Namespace. Class and Member names. And all these details are passed on to the next sub division Class file generator that generates a Class file with the categorise names and Member names specified in the XML register using CodeDOM.
The CodeDom namespace contains types for managing the generation and compilation of source code in supported programming languages. label generators can each create obtain code in a particular programming language based on the coordinate of label enter Object copy (CodeDOM) source label models consisting of elements provided by the CodeDOM namespace. The Class file generated using CodeDOM is given as an enter to the next Module.
The Class file given to this module is complied in run measure using CodeDOM compiler. While using CodeDOM compiler the hive away options should be set to create Dynamic Link Library (DLL). This DLL is the create of Runtime Interface creation and deployment toolkit.
This DLL contains functions for retrieving and updating data from the database like Gettable Values and UpdateTable respectively. Therefore the Application which uses this DLL be not connect to the Database or use any SQL queries to get or set the data in the database.
The below screen shot is a Runtime Interface creation and deployment toolkit Application that connects with the database server and displays all the datatypes listed in the Server. The user can decide the Database to view its tables. Stored procedures and views and the user can decide the allot tables stored procedures and views and create a XML file by clicking create XML register button.
This XML file is then construe and converted to class register and compiled internally by using CodeDOM label generator and CodeDOM compiler respectively. The output ordain be a DLL with label of the selected Database.
The Client application that needs the data from the Database should use the DLL provided by the Runtime Interface creation and deployment toolkit to access the Database. As the disapprove of the Class should be created in the run measure Reflections must be used in the client application to access the member variables and the methods of the categorise.
Reflection enables a schedule to dynamically analyze and sight elements (such as fields methods constructors and attributes) of types (such as classes interfaces and structures) in existing assemblies. When this write information is obtained it may be simply displayed Or the types may be instantiated accessed and invoked in a very dynamic and interactive manner making it possible to apply interesting programming tools such as an interpreted evaluate script language. The Client application should implement this concept to Get delay information from the database and show the information to the User. Here there is no enjoin interactions between the Client application and the database and all SQL Queries must pass through the DLL.
The below screen shot is a Client application that displays all the Tables in the database VisionRD. When any table is selected the table information is updated in the Data grid displaying data to the user. The delay information could be modified and the database could be updated by using the Update button.
In. Net Assemblies undergo a version be as move of its identity. As such two assemblies that different version numbers are considered by the runtime to be completely different assemblies. The version be is stored in the assembly bear witness along with other identity information including the assembly label and public key as well as information on relationships and identities of other assemblies connected with the application.
When an assembly is built the development drive records dependency information for each assembly that is referenced in the assembly bear witness. The runtime uses these version numbers in conjunction with configuration information set by an administrator an application or a publisher to fill the proper version of a referenced assembly. The runtime distinguishes between regular and strong-named assemblies for the purposes of versioning. Version checking only occurs with strong-named assemblies.
Side-by-side execution is the ability to store and execute multiple versions of an application or component on the same computer. This means that you can have multiple versions of the runtime and multiple versions of applications and components that use a version of the runtime on the same computer at the same measure. Side-by-side execution gives you more control over what versions of a component an application binds to and more control over what version of the runtime an application uses. Support for side-by-side storage and execution of different versions of the same assembly is an integral part of strong naming and is built into the infrastructure of the runtime. Because the strong-named assembly's version be is move of its identity the runtime can store multiple versions of the same assembly in the global assembly lay aside and load those assemblies at run measure. Although the runtime provides you with the ability to create side-by-side applications side-by-side execution is not automatic.
