The client obviously needs a way to be notified when the calls complete and be able to harvest returned values or catch exceptions.If the service were to allow to call back to its client it could result with a deadlock if the client will call to the service as a result of the callback to the client. This allows windows to continue its essential processes in the background and stops windows from crashing.Also windows wont refresh, the user may get impatient, thinking that the comp is crashed and restart.One thing you may want to do with your macro to make it run faster and to prevent distracting flashes on the screen is to turn off screen updating while the macro is running.The following macro lines will, respectively, turn off screen updating and then turn it back on in a VBA macro.The idea is to use the first line near the beginning of your macro, and then use the second line near the end.Thus, the main body of your macro can do its work behind the scenes without the necessity of stopping to update the screen.
It reads data from textfiles and puts them in SQL databases.
There are many different articles and post on improving Excel performance.
What I personally was missing was a simple, comprehensive, short overview of how the performance of VBA macros can be improved without needing to read through long articles on how the Excel compiler works bla bla bla.
To allow callbacks, you need to configure the service for reentrancy – that is, release the lock before the callback, as show in the demo.
If the callback needs to execute on a particular thread (such as updating the UI with Windows Forms), you must marshal the call.
