【Abstract】 This article studies the way to draw waveform with the windows API function under LabVIEW platform. By introducing an essential method of clasp technology to capture the system’s WM_PAINT messages, which is original, several problems such as graph refreshing and redrawing and displaying were solved. Seamless link of LabVIEW and the windows API was achieved through the dynamic link librarys(DLL), which increased of flexibility and efficiency of Labview programming.更多还原
