How can I debug a Delphi Runtime Error 217?

Debugging a Runtime Error 217 involves careful analysis of your code. Start by enabling exception breakpoints in the Delphi IDE (Debug -> Options -> Breakpoints). This will pause execution closer to the point of the error. Examine the call stack to see the sequence of functions leading to the error. Use memory debugging tools like FastMM4 or EurekaLog to detect memory leaks or corruption. Single-stepping through the code and inspecting variables can help pinpoint the exact location of the illegal memory access.
