Is there any way to get values of DR0-DR3 from OllyDbg? Or any other way to check what hardware breakpoints are set?

OllyDbg menu – Debug – Hardware Breakpoints

or in C++

CONTEXT Context;
Context.ContextFlags = CONTEXT_DEBUG_REGISTERS;
GetThreadContext( hThread, &Context );

Lord_Looser: Thanks, I was looking for an API in the plugin SDK and never thought of just doing it the usual way.. =)

psycho
right click in register pane (where eax,etc is seen) and click view debug registers shows all the debug registers are you searching for this or is it some thing else

oh me anon: I was after a method to get them programmatically in a plugin. Its solved now. =)

Yes, you produce and exception and go to the exception handler, in the stack, the 3 o 4 value point to the values of the four HARDWARE BPX, try
