Why Does the ReadWrite Selection for DataSocket Mode Not Work? I am using DataSocket in LabVIEW 7.0 through 8.0.1 . When I open up a connection to DataSocket and specify ReadWrite mode (an input of 2 to the mode parameter), neither a read nor write seem to work. This only seems to be a case when I have both a read and write on the same URL: http://digital.ni.com/public.nsf/allkb/B338A7D00F6D04F986256DAB0060596A

為什麼DataSocket的ReadWrite模式不行用 我在使用LabVIEW7.0與DataSocket. 當我開啟一個DataSocket, 使用ReadWrite模式, 如果同時有一個DataSocket Read VI與一個DataSocket Write VI, 那整個DataSocket就不會正常運作, 我將不能寫讀資料. 為什麼會這樣? URL: http://digital.ni.com/public.nsf/allkb/AD064495E2EF0F5086256F47001321E0

데이타소켓(DataSocket)에서 ReadWrite 가 동작하지 않습니다. LabVIEW 7.0 에서 데이타소켓을 사용하고 있습니다. 데이타소켓 커넥션을 열고 ReadWrite 모드로 지정할 때에, DataSocket Read VI 와 DataSocket Write VI 가 동시에 있을 경우에는 데이타를 보내거나 읽거나 하는 것이 둘다 안됩니다. 왜 이런 현상이 일어나며, 어떻게 해결할 URL: http://digital.ni.com/public.nsf/allkb/8522E6624E0FCB0C86256F490005171C

Static Assignment of DataSocket Client Ports I am trying to use DataSocket to communicate through a firewall. Before doing so, however, I must open a port through my firewall to allow for the communication. Is there a way to make the port number that is used by DataSocket clients static or is there a limited range within which the URL: http://digital.ni.com/public.nsf/allkb/FCF8A1464BD2F6D686256B59007C9A6F
