I am trying to make a simple handler and this is my code. If excution can be continued, after calling user defined cleanup procedure I try to resume execution by restoring ebp, esp and setting new offset but it doesn't seam to work.

What is wrong with this code:

SEHFinalHandler	PROC ExceptionPointers	:DWORD

	call lpUserFinalHandler

	test eax, eax

	jz @F

		mov eax, ExceptionPointers

		mov eax, [eax].EXCEPTION_POINTERS.pExceptionRecord

		mov eax, [eax].EXCEPTION_RECORD.ExceptionFlags

		test eax, eax

		jnz @F

			mov eax, ExceptionPointers

			mov eax, [eax].EXCEPTION_POINTERS.ContextRecord

			mov ecx, SEHSavedData._ebp

			mov [eax+0B4h], ecx

			mov ecx, SEHSavedData._esp

			mov [eax+0C4h], ecx

			mov ecx, SEHSavedData._offset

			mov [eax+0D8h], ecx

			xor eax, eax

			dec eax

			ret

	@@:

	invoke MessageBox, NULL, offset szExceptionAutoGeneratedErrorMessage, NULL, MB_ICONEXCLAMATION or MB_SYSTEMMODAL

	xor eax, eax

	inc eax

	ret



SEHFinalHandler	ENDP

CONTEXT.regEip is at B8h, not D8h.
