请问如何在labview 中调用api 例如createprocess Public Declare Function CreateProcess Lib "kernel32" Alias "CreateProcessA" (ByVal lpApplicationName As String, ByVal lpCommandLine As String, lpProcessAttributes As SECURITY_ATTRIBUTES, lpThreadAttributes As SECURITY_ATTRIBUTES, ByVal bInheritHandles As Long, ByVal dwCreationFlags As Long, lpEnvironment As Any, ByVal lpCurrentDriectory As String, lpStartupInfo As STARTUPINFO, lpProcessInformation As PROCESS_INFORMATION) As Long 其中的数据类型如何变换 对照的数据类型表在哪里可以查到? null 如何赋值?我想做一个调用外部程序 等待程序完成 然后去程序返回值。使用到如下api createprocess WaitForSingleObject GetExitCodeProcessd 等谢谢!
