Hi, I have a problem with my app.exe build. I attach a simple code; the Vi open and close a TDM file. If I run this Vi in Labview works fine. If I build the application.exe on a notebook and I run it I got "Application crash with error ntdll.dll 00018fea". I've tried to build the Vi on another Pc Desktop with Labview and here if I run the exe it works fine. On the two PC I have LV8.5; the build options are the same. On the notebook I've try also to reinstall LV8.5 but I got the same error. Can you help me? Thanks a lot

Hi guys, in my program I acquire continous data with PXI-4472 and DAQmx (fs:40960Hz, 4096 samples). I run this on two PC, one dual-core, the other one-core. Sometimes on the dual-core PC, the acquisition seems "paused" and it "restart" after 5sec but the buffer could go on overflow. In these 5 sec on the task manager I saw one of the two core works at the 100%. On the other PC one-core the program always works fine. (I've got this problem also on a notebook dual-core with a 4472 Simulated device) Someone of you got also this problem ??? and better someone can help me ? Thanks a lot !!! Michele

hi in my application I need to apply an A-weighting filter to my microphone signal; sincerly I don't want to buy S&V toolkit only for this function... about you is possible doing it other way ??? I know that the transfer function (http://en.wikipedia.org/wiki/A-weighting) in the Laplace domain but I don't know how to apply it. Thanks a lot !!!

Hi Luois, first thank you for the reply. I'm using a 6070 multifunction board. I acquire packet of 4100 samples; Sampling rate: 500000 s/sec; Scan rate: 41000 s/sec; I use DIAdem DAC to acquire and analyze. I'm not sure of this parameters also because I've see that if I change some of them the freq of the pulse change... Thank you

Hi, when I acquire a signal AC of my phonometer and I do a FFT I obtain a pulse of 80dB at 13600 Hz without noise in the room; the same problem succed when I disconnect the cable in input....So I think it's an electric noise...do you know which can be the source of this noise ?? Thank YOU
