VC调用VB的dll
有静态和动态两种，静态的需要lib而动态的只需要一个dll就可以了（但是要知道函数的定义一般是头文
件）动态相对复杂一点！但是掌握了也不是很难
//第一步 定义函数指针就是你要调用的函数，参数必须一致，不然就内存泄露
typedef HANDLE (PASCAL * OPEN)(char *,int);
//第二步 定义本地函数
//一般前两步都在头文件里面声明
OPEN open;
//第三步 加载dll
HMODULE m_hLib;
m_hLib ::LoadLibrary"E:\\yewufuwu\\TERMINALDLL\\Debug\\TerminalDLL.dll");
//输入相应的路径
if(m_hLib == NULL )
{
MessageBox("动态连接库没有找到!!!","LoadLibrary",MB_OK);
return ;
}
//第四步
else
{
MessageBox("动态连接库成功打开...","LoadLibrary",MB_OK);
open=(OPEN)GetProcAddress(m_hLib, "OpenDevice");
}
//第五步
long handle = open("EF",1)；
动态库下的函数如下
//*************打开终端*****************************************
HANDLE __declspec(dllexport) WINAPI
OpenDevice(char * szType,int nType)
{
hReader&

就这么一个函数就解决了那位仁兄3天多的工作
唉~！真被一个函数玩死了
这里顺便帖出来吧
