c++builder 如何调用VB写的DLL？
这是VB下调用的函数说明：
Private Declare Function Inp Lib "inpout32.dll" Alias "Inp32" (ByVal PortAddress As Integer) As Integer
Private Declare Function Out Lib "inpout32.dll" Alias "Out32" (ByVal PortAddress As Integer, ByVal Value As Integer) As Integer
我在BCB中导入这个DLL时出错，请各位指教？（这个DLL是读写并口的）
多谢妖哥，试了OK

a[i] = 0;
