Hi Cecil, Yerp, Im with you, I actually mentioned in my previous post Im going to try launching a child process and have it take care of the sqlite interaction. That way I can keep my gui code nice, light and predictable.
A trick I can use is to support some sort of async messaging between my two processes, then I can poll my sqlite process say once a second for new events, and shoot events at it whenver I want to. Eg. How many rows do you have? What is the contents of rows 1-100? Can you filter down so you only show the rows with contents "xyz" I have done plenty gui coding in the .Net world and these are hoops im not quite used to jumping through but timers do not feel like a workable solution.
