vb怎么调用vc结构体数组？
vc提供的函数是：DIANLI_API int WINAPI My_DownLoadUsersData(int comm, char* buff, int count);

vc提供的dll中这样定义了一个结构
typedef struct user_tag{
unsigned short userID;
char name[15];
char userName[15];
char passWord[15];
unsigned char userRight;
}USER, *PUSER;

vc调用是这样的：
USER userData[] = {
{197, "0197", "zhangsan098", "123456", 255},
{198, "0198", "zhangsan099", "123456", 255}
}

memcpy(data2,userData, sizeof(USER)*2);
a = DownLoadUsersData(4,(char*)data2,2);


请问vb如何调用，如何声明，user_tag传递个数是不定的，上面vc的例子只给两条。

[解决办法]
VB中自定义类型需在类中定义才能作为函数参数传递

C/C++ code

typedef struct user_tag{     unsigned short  userID;     char name[15];     char userName[15];     char passWord[15];     unsigned char userRight; }USER, *PUSER;DIANLI_API int WINAPI My_DownLoadUsersData(int comm, char* buff, int count);
