"FRONT OFFICE AUTOMATION SYSTEMWindows application: This application applies in the run time and design time, is used in the designing offorms in new projects. The Windows application can be used by any VS .Net supportinglanguages.Console application:This application applies in the DOS prompt and run time, is used in the designingof forms in the new projects. The Console application can be used by any VS .Netsupporting languages.Code window is available with <name.vb> for VB .Net and <name.cs> forC#.NetWeb application: This application applies in the runtime and design time, is used in the designing ofweb forms or Web pages in the new websites. The Web application can be used by any VS.Net supporting languages. Crystal reports:This application applies in the creation of tabular column. Generally the crystalreports are ignored by VS. Net. These applications are used in the generation of tabularcolumns in the new projects. These Crystal reports can be used by any VS .Net supportinglanguages.Control libraries:This application applies in the creating of assemblies. It is the combination of oneor more .dll and .exe files. These applications are used in the assemblies in new projects.The Crystal libraries can be used by any VS .Net supporting languages. There are twotypes of assemblies such as single file assemblies and multi files assemblies.DEPT OF IT, PDCE 2009-2010 Page 4 FRONT OFFICE AUTOMATION SYSTEMAdvantages of VB .net:? Not case sensitive.? Faster in execution while compare to other .Net languages.? It has migrated.? The future is newly adopted technology from the existing VB 6.0 (a productdeveloped by Microsoft for rich front end screens).Snippet:A future introduced VS .Net 2.0 version to make the users very familiar with thestructure of different control statements used in the programming.Type casting:Conversion of one data type to the other data type implicitly by the compiler andexplicitly by the user.Boxing and unboxing in the .Net:Boxing is the process of converting value (integer type) type to reference (string type) type, and unboxing is the process of converting reference (string type) type tovalue (integer type) type. .NET FRAMEWORK:? Framework is different from Integrated Development Environment (IDE).? We use Integrated Development Environment (IDE) as VS .Net.? .Net framework is a programming module of .Net.? .Net framework is combination of basic class libraries (BCL) and commonlanguage runtime (CLR).DEPT OF IT, PDCE 2009-2010 Page 5 FRONT OFFICE AUTOMATION SYSTEM? BCL includes root name space, OOP’s concept ,web services, xml, active data object (ADO).Imports System. Data- here imports is a keyword used to inherent various name spaces intothe .Net environment and System is the name space of a logical collection of class, methodand properties etc.CLR mainly consist of three parts:Memory managementmanages how much memory is allocated.Garbage collector allocates and release space for object usage.CTS (common type system) every variable should be either value type or reference type which is a mandatory condition.Root name space:System.windows.Form developing for the windows application.? System. Reflection assembly applications.? System.io files operations.? System.Drawing Microsoft paint brush operation we can change size, color,of the font).The .NET Framework provides a runtime environment called the CommonLanguage Runtime or CLR (similar to the Java Virtual Machine or JVM in Java), whichhandles the execution of code and provides useful services for the implementation of theprogram. CLR takes care of code management at program execution and provides variousbeneficial services such as memory management, thread management, securitymanagement, code verification, compilation, and other system services. The managed codethat targets CLR, benefits from useful features such as cross-language integration, cross- language exception handling, versioning, enhanced security, deployment support anddebugging.
