Thats what I needed.

TDMS format is too big. Then I need lots of disk space.

Thanks for your respons, only thats not exactly what I ment. I want the executable to get the path of the .dat file and open it.

Hi everybody, I'm acquiring data and saving that on my disk as .dat. Now I want to later open and analyse the data. So I'm busy with writing a VI thats read the .dat file. The VI is going to be a .exe file. This results in that I can set all my .dat files to that executable. The problem is: When I run my .exe, it still want me to select the .dat file I want to open. But I want it to read the path of the .dat file i'm opening Hopes my problem is clear ____________ Michael ten Den

Thank you rolfk, The VI already crashes when it is opened. I store all my SubVI's in a project. So I expect it would not be a incorrupted subVI, but I don't know that. So I'm going to try some stuff with it. Lucky I had a backup. But from 2 days earlier. This problem shows that you can do a lot in 2 days

Thanks, going to check it out

You mean that it can be a problem in one of my subVI's? Because my main program, where the error occured, no longer works and opens. ____________ Michael ten Den

I was busy to program a program that reads from UDP CAN messages. When I hitted the run button, LabVIEW crashed. I had the error: "LabVIEW 10.0 Development System werkt niet meer" (English: "LabVIEW 10.0 Development System doesn't work anymore".) LabVIEW 10 coudn't find a solution for this, so it quitted. I restarted LabVIEW and opened my VI and the same error occurred. I can still open everything and my project in LabVIEW, but not my VI. I tried on another PC and it still doesn't work. Luckely I have backup, but how to avoid for a next time this problem. Has somebody experience with this problem? *Sorry if I putted this topic in wrong section. ____________ Michael ten Den

Thank you for the respons. I have a 1 kHz sample rate, but maybe its smarter to save that and only show 100 Hz or something like that. Because if their is a peak, it will also be showed with lower rate. Or I maybe smarter to build a hysterese so if it get higher than a value it will give me the 1 kHz in an other chart I'm now saving my files as .DAT file. I build a .DAT reader so I can open my data after measurement. But saving to a text file will maybe be better. I just have to see it yet. Unfortunaly I'm a windows user ____________ Michael ten Den

Thank you Antoine, I know the solution now, thx. ____________ Michael ten Den

My fault. I chosed the file, but forgot to press 'Attach this file'. ____________ Michael ten Den

Hello, I have indent 3 items under 1 item and when I select that 1 item, I want to have automaticly selected the tree indented items. (see attachment) Its for a graph, So I can display them together or seperated. This is for 3 indent items, but I have also 2 items with both 18 indent items under them. ____________ Michael ten Den

Ok, but do I have to buffer lastest data of every ID in a different buffer, or is there a better solution?

I have now 4 while loops running: - Continue receive and transmit CAN messages in/to queue - Consumer loop, initialize, read the CAN message from queue and put them in the right array, a display case for my front panel update, and a few several items - producer loop, time out 1 ms, sends 'read' in to consumer loop, update display, send CAN message and stop event - Datalogging loop, save every 10 secs all arrays in same file and create every 5 min a new map for the data I thought that put the messages first in arrays will be easier for me to plot in on my front panel and save it. Apparently it isn't the right way. @ superS-5 I will build a disable script for the ID's I don't want to measurement at that time, but can't delete them because they will be necessary for other test. Thanks @ ShaunR I assume you mean direct logging to a file instead of array? But how to plot it then? Some additional information: - The program has to run several hours - The x-as will be max. 5 minutes, what continous with the time. - Sample rate of 3 pot. meters, 1 kHz. It's not all clear to me right now what the best reliable methode is. ____________ Michael ten Den

Thanks jgcode & Matt, I'm going to monitor the suspension of a car with 3 lineaire potetion meters. The important of all is that I have sample rates of 1 kHz. Higher is even better. So the array will be quick huge. The LabVIEW program has to run the hole day on my laptop. I'm getting my info trough UDP. There is a CAN network on and with a Analog2CAN converter i'm reading my potentio meters. I get about 200 ID's in my program and I'm putting them in several arrays, but is this the best, less failure, fast way? Is waveform then still better? Looking forward for your answers, ____________ Michael ten Den

Hello, I'm new on this forum and this is my first post, so excuses me if I'm posting it on the wrong place. I busy with getting data from 3 lineair potentiometers. Now is my question. Does it matters for saving speed and memory if I store the data in seperated array's with time stamp in it or all 3 in 1 array with time stamp. (see attachment, Excuses of the text with (int) in it. Off course is it a dbl) ____________ Michael ten Den
