Using SQL Server Query Notifications in Qt application

[andrzej]

Does anybody have experience in using SQL Server Query Notification mechanism in Qt applications. I need my application to be notified when data has changed in db. Currently the only option I see is to use polling on the application side. I have read some examples and docs provided by Microsoft about SQL Server Query Notification but all of them seem to be related to .NET context, where your have specialised classes for this like SqlDependency.

I would like to get the general idea whether it is worth trying to get this mechanism working or I should stay with polling.

Thanks
