Dear all: I have some questions about the DAQmx, my questions is listed in following: when I only use the DAQmx AO or AI function, that my program can running normally, but , when I want to combine these AO&AI functions in the same program, my progrm appear some error information("error-200251 occurred at DAQmx Start Task.vi" Possible reasons: No DMA channels are available), why my program appear this error information?? I hope everyone can help me this question, thank you many much!! Download File:post-756-1120223783.vi

Dear all: I have a question is needed everyone to help me..... my question is listed in following: 1. if I have a equation in the frequency domain, that is " G(jw)H(jw)= jw/(jw+5). 2. so, I hope use this equation to calculate it's amplitude and phase, then use these results to plot a "Bode" graph using formula node. How can I do?? Thanks!!! :worship:

Dear JackHamilton: I have been tried your example program about "Splashscreen", but I find some problems want to ask you, these problems list in following: 1. Whether this example program only running on LabVIEW 6.1? because my LabVIEW version is 7.0, a vi(splashscreen_Rev2.vi) not found when I open this example program. 2. In your example program, why first to open main program then minimize the front panel window? If I exchange this order, frist open "splashscreen.vi" then to open main program, whether can to finish a program that functions as same as your example program?? Thanks!!

Thanks everybody!! :worship: your reply let me learning more technique on LabVIEW. thanks again!!
