In the auto assembler,sometimes,when you specify a symbol but not its module,it may not inject code successfully:
example code:
Code:
msvcrt.exit:
ret
db 90


After this,go to the memory viewer,rightclick,choose goto,and type in msvcrt.exit,now,after reclicking 'goto',try typing in the word exit,the bytes are different,in the first one you will see a ret followed by a nop,everything is fine,but in the second one,you'll notice a 'mov edi,edi',this because the symbol handler does not make a difference between msvcrt.exit and msvcrt._exit,it spells both of them as exit.
More details in attachments.
