Design pattern to separate messages from actual process.

Question

I am having a C# application to sync data between PC and palm devices. There are codes written like below:

  showMessage("synchronizing Table1");

  Sync(destTable1,sourceTable1);

  Sync(destTable2,sourceTable2);

  showMessage("synchronizing Table2");
  // more code

How do I separate the actual process of synchronizing from displaying message? Which design pattern to follow?

Thanks in advance...

Answer 1

You should run the sync process on a separate thread and inform the main thread of the progress. The main thread displays messages.

You can obtain this behavior using the BackgroundWorker class that has all the feature ready.
