Changing the convoy set to include a customer ID field would also impact the number of orchestrations running in perpetuity. Each new customer ID would end up creating a new orchestration, which could result in hundreds, if not thousands, of constantly running instances. This situation is not particularly desirable from either a performance or management perspective. To address this issue, you can implement a timeout feature allowing the orchestration to terminate if subsequent messages are not received within a specified period of time. Take the following steps to implement this enhancement. The updated orchestration is shown in Figure 5 42. 1. 2. 3. Add a Listen shape in between the Send shape and second Receive shape. Move the second Receive shape to the left-hand branch of the Listen shape. Add a Delay shape to the right-hand branch of the Listen shape. Configure this shape to delay for the appropriate timeout duration. In our example, we set the timeout to be 10 seconds by using the following value for the Delay property:

using namespace System; using namespace System::IO; // a native class class FileNative { // a CRT file pointer FILE* fp; public: void Open(const char* filename) { int err = fopen_s(&fp, filename, "r"); if (err) { printf("Error opening file %s. Error code %d.\n", filename, err); } } int Read(char* line) { int val = fread(line, 1, 1, fp); if (feof(fp)) { return 0; } return val; } void Close() { if (fp) fclose(fp); } }; // a managed class that contains a managed resource (StreamWriter) // and a native resource (fileNative, a native class containing a native file) ref class FileConverter { FileNative* fileNative; StreamWriter^ sw; public:
