Hi, I have two questions about saving large files. For example I want to save 2d array - 8 columns, 100000 rows to file. Numbers like : 0,000875 -1,086301 -0,0254 ... I know it's sipmle - normal saving to file, but it takes lot of time and this saved file is big. Is there any better and faster way to do it?? Most important is saving speed. Second question is similar, also about saving large data. Let's have the same data and we want to save it in Mysql. What should be DATATYPE in our database sql if we want to save in it so big data in one row. How should it look like?? I thought about saving to binary files and stuff like that, but I don't know how to do it properly in labview with numbers like :0,000875 -1,086301 -0,0254 ... Do you have any ideas how to do it??

I have one more question. I'm using TCP connection between "serwer program" and "client program". Serwer program is running all time (send data with TCP), client program is running for a short time (collect data), when I'm starting next time client program (serwer is running all time) I can't collect data, it is working but without connection. Why? What to do if I want to collect data each time when I will run this client program? Thanks for help in advance.

Thanks, I've tried using TCP connection and it works:) I thought that TCP will be to slow so I've tried UDP, but now when my programs are working with TCP I see that it is even quite fast (at least for my needs). Thanks!

QUOTE (normandinf @ Jul 18 2008, 09:46 PM) I've tried doing this way, but I have still the same problem. I've check , and always its only 1024 data sent, never more. I think this is because of Windows. How to sent data in many packages. For example if I want to send more than 2000 probes, what I need to do? For my programs I'm using Daq simulations, how will this program look like for real Daq measure? Does it will be the same problem with sending data? I dont have yet NI Daq card, I want do do first program, and then I will be testing it on real NI card.

I want to send data to more than one computer not always in LAN connection. There will be one serwer program, and lots of clents programs , which will be reciving probes from serwer. I thought that for this situation better is UDP.

HI, I want to make two programs, first will be sending data from daq (4 channels, 1000 probes) , second will be receiving data from this first program. I have one problem because this second program receive not the same numbers of data and those charts are diffrent. First two pictures is sending program , 3,4 picture is receiving program. Please help me, how to do this second program to read the same number of data which is sending this first program. Thanks

I want to do an aplication in labview which can recognize devices connected to my computer or LAN . When I will write correct port number and press enter , this aplication should recognize measurment devices (of course NI devices) in my network, for example if this device is USB or any other Daq and giving me full name and number what kind of device is it. Do You have any similar programs made in Labview?? Could You give me any tips how can I do this? Is it possible? Thank You for reply:) Paul
