  1. Hi, I have a table with approx. 100 rows and 10 columns, and I need to get the index of user-clicked-row. Can I do it in DAQ? I am using DAQ 5.84 Developer version. Any help would be appreciated.
  2. Great, my problem solved. I used "nvarchar" data-type. Now DF display my text correctly. Cheers, B)
  3. Hello, I need to read an array of String (about 10 elements) and display (no modify) all of them on pages. But I got 2 problems: 1. DAQ convert my String to number (I've used db.Query() and db.QueryToClass(), still same) 2. I can't display my text on page Can you help me solve this problem?
  4. Thanks, you save me a lot of work. I install v5.84 and it work fine. Cheers,
  5. Hi, I use DAQFActory Pro 5.7, installed on a clean Windows XP SP3 (no IIS, no other services or other programs using those ports - I used "netstat -a" command). Am I using old DAQFActory version that doesn't support more than one Ethernet server in same document? I need to know because I'm going to buy latest DAQFactory Development Edition. Cheers,
  6. Hello, First, I create a file named it "Test IP.ctl". Then I add new Ethernet server like in "DAQ_01.png" (listen on port 8000, NULL Protocol). Then I add new Ethernet server (in same document) like in "DAQ_02.png". But whenever I click button "Save" like in "DAQ_02.png" my PC hangup. And I don't know why. In fact, I need DAQFactory act as server and listen on ports: 8000, 8001, 8002, 8003 in same time, same PC. But it sounds stupid if I create 4 documents and then run 4 DAQFActory instances. And I can't dynamically create Ethernet server in DAQFactory. Do you have any idea? Can I use DAQFactory for my job?
  7. I start a new document, named it "Test.ctl". Then I use Quick->Device Configuration->New Ethernet server, named it "Test8000" because it listen on port 8000 (TCP). Can I add more Ethernet server listen on port 8001, 8002, 8003,... in "Test.ctl"? My PC hangup when I add new Ethernet server, I use DAQFactory Pro 5.
  8. Can I create more than one Ethernet server in one document (.ctl file)? I tried many times, but whenever i add second Ethernet server my PC hangup.
  9. Yes, i want DAQFactory act as server. Can you show me how to create an Ethernet server in a sequence?
  10. Hello, Assume that my IP is And I have some device with IP:,, I've read the manual, page 303, i know that "DAQFactory only supports one connection per port for the server". So can I think i must create 3 sequences, each sequence open a specific port and listen for incoming data. But I don't know how to do that. Can you help me or suggest me another method?
