It would help a lot if you invested a minimal effort in reading the documentation. You will not get very far with that attitude.

start:
;invoke DeleteFile,addr slog not needed
invoke CreateFile,addr slog,GENERIC_WRITE,FILE_SHARE_WRITE,NULL,OPEN_ALWAYS,FILE_ATTRIBUTE_NORMAL,NULL
mov hfile,eax
invoke WriteFile,eax,addr wbuff,15,offset BytesWritten,NULL  ; 15, not 500
;mov hfile,eax you are not getting a handle here...!
invoke CloseHandle,hfile

invoke WriteFile,eax,addr wbuff,15,offset BytesWritten,NULL  ; 15, not 500
