以下这个DLL库在VB中如何定义啊，试了好多种方法都不对
int WINAPI PSUpChar(int nAddr,int iBufferID, unsigned char* pTemplet, int* iTempletLength)

------解决方案--------------------
你的定义是什么？

------解决方案--------------------
int WINAPI PSUpChar(int nAddr,int iBufferID, unsigned char* pTemplet, int* iTempletLength

==>
public Declare Function PSUpChar Lib "xxx.dll" (ByVal nAddr As long, Byval iBufferID As long, byval pTemplet As string,iTempLetLength as long) As long

------解决方案--------------------

VB code

Dim a As String
a = Space(512) '<-凭经验，字符串应该由调用者分配空间
bb = PSUpChar(&HFFFFFFFF, 0, a, 512)
