How to keep an active "Stop button" while application is reading file

I have an Application C# handling file reading, building index on this file, using dll wrapped with SWIG. The dll is originaly programmed in C++.

Dll reports back to the the C# programm throug callback/delegates. Among others, it reports index building(%). One callback function can receive (stop order) to stop reading file/building index. How ever i do not know how to keep the stopbutton activ while this file reading is going on.

I have not tried threading before.

Can I keep this one button active running it on a separete thread ?

If your read is happening in a loop, try Application.DoEvents(), it'll force the application to flush all pending actions. The other option is to run the read process in it's own thread, or a background worker.
