The Caché Managed Provider SolutionCaché is not required on computers that run your Caché .NET client applications, but they must have.NET Framework 2.0 and a TCP/IP connection to the Caché Server.1.2 The Caché .NET Sample ProgramsCaché comes with a set of sample projects that demonstrate the use of the Caché .NET binding. Thesesamples are located in the /dev/dotnet/samples/ subdirectory of the Caché installation(see Default Caché Installation Directory in the Caché Installation Guide for the location of on your system).• adoform — A simple program to access and manipulate the Sample.Person database. The sameprogram is presented in three different Visual Studio languages: C#, Basic, and C++.• bookdemos — Contains complete, working versions of the examples in this document. The projectis a small, easily modified test bed for short sample routines. All of the relevant sample code isin one file: SampleCode.cs.Before running this demo, you must regenerate the ..\bookdemos\WizardCode.cs file, which containsproxy classes for the Sample package (see Generating Caché Proxy Classes for detailed instructions).• console — A console program that demonstrates the bare minimum requirements for a Caché.NET project.• mobiledevice — Similar to adoform, but demonstrates how the mobile version of the CacheClientassembly deals with transient connections.• objbind — Similar to adoform, but demonstrates how to write code that uses both ADO Providerobjects and Caché proxy objects in a complementary fashion.Before running this demo, you must regenerate the SampleExport.cs file, which contains proxyclasses for the Sample package (follow the instructions in Generating Caché Proxy Classes, butset the output file to ..\objbind\SampleExport.cs rather than ..\bookdemos\WizardCode.cs).All of these projects use classes from the Sample package in the SAMPLES namespace. You can useCaché Studio to examine the ObjectScript code for these classes.Important:Always make sure that you have generated proxy class files for the latest version ofthe classes in the Sample package (see Generating Caché Proxy Classes for detailedinstructions). A mismatch between Caché classes and their proxy classes will causeyour program to fail. As mentioned previously, new proxy class files must be generatedfor the bookdemos and objbind projects.4 Using the Caché Managed Provider for .NET
The Caché .NET Sample ProgramsNote:Most of these samples are written only in C#. If you decide to convert a sample to VisualBasic, bear in mind that a new Visual Basic .NET project will have a default namespace thatcontains every class defined by the project. If this is ignored, code such as:Dim p As New Sample.Personp = p.OpenId(CacheConnection, "1")will fail because the root namespace has not been referenced. This can be easily correctedby disabling the "Root namespace" option in the project preferences.Using the Caché Managed Provider for .NET 5
