[Tommey]

I have read the .d7d data files with the DWDataReaderLib.dll in labview,i can get the data and time_stamp through allocate memory (data and time_stamp) then call DWGetScaledSamples ,but when i want to allocate the DWChannel structures then call DWGetChannelList to get channel list properties,it will fail .In fact,now i don't konw how to get channel list .In my program,i have allocate the DWChannel structures ,but it doesn't export the data ,and when i wire the array of channel list,the labview will destroy.thanks
