| Abstract: | The property of activeX control is introduced,the principle of using ActiveX control and the method of register event callback are both elaborated. And the problem of data transfer in event callback programming is solved,as a result,the real-time data transfer and data processing is ensured. The data lost or data covered is avoided. The MScomm32 ActiveX control is taken as an example to introduce how to program to solve the event callback and data transfer in LabVIEW7.1.The method is universal and common used,which can enlarge the LabVIEW itself. |
