Declare Function CH375ReadData Lib "CH375DLL.DLL" (ByVal iIndex As Long, ByRef oBuffer As Any, ByRef ioLength As Long) As Boolean 中的數(shù)據(jù)類型Any是什么數(shù)據(jù)類型？VB的書上好像介紹的不多？還有下面的： Declare Function CH375GetStatus Lib "CH375DLL.DLL" (ByVal iIndex As Long, ByRef iStatus As Long) 能舉個使用它的例子嗎？（用VB）

Any相當(dāng)于c語言里任意類型的指針,在vb里任何引用類型的值都可以賦值給Any

BOOL WINAPI CH375GetStatus( // 通過CH375直接輸入數(shù)據(jù)和狀態(tài) ULONG iIndex, // 指定CH375設(shè)備序號 PULONG iStatus ) // 指向一個雙字單元,用于保存狀態(tài)數(shù)據(jù) // 位7-位0對應(yīng)CH375的D7-D0引腳,位9對應(yīng)CH375的RXD#引腳,位10對應(yīng)CH375的REQ#引腳

這個函數(shù)在應(yīng)用層軟件里很少用到,不需要掌握
