The following code example shows how to use the SharedPropertyGroupManager class to create a SharedPropertyGroup.
#using <System.EnterpriseServices.dll> using namespace System; using namespace System::EnterpriseServices; using namespace System::Reflection; [assembly:AssemblyKeyFile("..\\common\\key.snk")]; [assembly:ApplicationName("ReceiptNumberGenerator")]; [assembly:ApplicationActivation(ActivationOption::Library)]; public ref class ReceiptNumberGeneratorClass { public: // Generates a new receipt number based on the receipt number // stored by the Shared Property Manager (SPM) int GetNextReceiptNumber() { bool groupExists; bool propertyExists; int nextReceiptNumber = 0; PropertyLockMode lockMode = PropertyLockMode::SetGet; PropertyReleaseMode releaseMode = PropertyReleaseMode::Standard; // Create a shared property group manager. SharedPropertyGroupManager^ groupManager = gcnew SharedPropertyGroupManager; // Create a shared property group. SharedPropertyGroup^ group = groupManager->CreatePropertyGroup( "Receipts", lockMode, releaseMode, groupExists ); // Create a shared property. SharedProperty^ ReceiptNumber; ReceiptNumber = group->CreateProperty( "ReceiptNumber", propertyExists ); // Retrieve the value from shared property, and increment the shared // property value. nextReceiptNumber = safe_cast<int>(ReceiptNumber->Value); ReceiptNumber->Value = nextReceiptNumber + 1; // Return nextReceiptNumber return nextReceiptNumber; } };
