这几天在做毕业论文，用得adlink的pci9118数据采集卡，vb编程，编译时总是出现：AI_9118_Config的参数不可选，怎么回事？请大侠指点，不胜感激。 Private Sub btnStart_Click() Dim result As Integer Dim i As Integer cobRange.Enabled = False cobSample.Enabled = False cobChn.Enabled = False cobTimes.Enabled = False picScreen.Cls PicScreen2.Cls result = AI_9118_Config(Card, P9118_AI_ExtG, 0, 1024) Range = range_value(cobRange.ListIndex) result = AI_ContScanChannels(Card, gnADChn, Range, gnBuffer(0), gnCount, CSng(nSample * 1000), SYNCH_OP) ShowData (gnCount) End Sub
