Easyest way to select data in a thread?

[Moehre]

Hello!

I read every thread about using THREADS and had a look at the Thread-Demo, but it seems to be much to complicated with all this pointer stuff.

Reading about threads I realized, that creating a thread in Delphi is simple (using "New" "Thread object"). Creating a new TOraSession and TOraQuery Object is no problem BUT: How can I access the data, that was selected in the TOraQuery Object created within the Thread? (Without any synchronizing problems) and how can I signal the main thread, that execution of the query is finished (using TEvent?). I think, that the TOraQuery object created in the thread would be killed when the thread is finished (using FreeOnTerminate)?

So, would you please be so kind to give a small, simple code example for selecting data in a thread?

The most easyest way for me would be an integrated function in TOraQuery like "TOraQuery.StartAsThread" property (boolean) and "TOraQuery.ThreadFinished" Event

Many thanks in advance

TOraQuery has the NonBlocking property. If you set it to True, the TOraQuery component will create a thread to execute queries and fetch data. You can just link the TOraQuery component to TDataSource and TDBGrid. After a thread has finished executing and fetching, data will be displayed in the grid.

You also can use AfterExecute and AfterFetch events of TOraQuery.

Many thanks for this info! You should consider to change the thread demo program and replace this c#-multiple-pointer stuff with nonblocking query usage ...
