如何用 VC 编写这个程序：当程序 SAMPLE 运行时，检测加密狗的密码，如不对，则将程序关闭？

[wealth]

现在要用加密狗来加密软件，但从来没有用过，现在已经买了一个加密狗，请问怎样开始？

如何用 VC 编写这个程序：当程序 SAMPLE 运行时，检测加密狗的密码，如不对，则将程序关闭？

有没有完整的例子？

[ifengfeng]

用定时器定时运行检测代码啊。

[ripyu]

这个加密狗太不正宗了

[luckyboy1979]

厂家应该有开发包的，这个我做过不是很难的。

[ifengfeng]

找到该程序的句并，发送关闭消息。

[wealth]

有一年多没碰过VC啦，以前只是用VC做过数据库，有没有一个实在一点的例子贴一下？

老大，你的ｄｅｍｏ里不是已经有代码了吗？自己研究一下了，不难。

[fanlongly]

楼主，这样的程序我也需要呀

[mfc168]

你要做一个读写串口的程序，先初始化你的加密狗的密码，可以写
在你的程序的InitialInstance 中写代码，读该串口，取得密码，如果不正确，则关闭程序
涉及的函数：
WriteFile
OpenFile
....
串口读写程序在这里有：

加密狗应有开发包，它的二次开发说的清清楚楚

[cymlife]

这个很简单吧。
加密狗厂商必须提供范例代码，否则你可以不买他的啊。

看一个使用说明,上面有API说明,

[wealth]

做程序想得有点烦了，不想去想了，有没有现成的能够运行的例子？

这是安装盘上的例子程序

========================================

以下是INFO.txt

=========================================
This directory contains KeyPro tools using in Turbo C/C++, Quick C,
Borland C++, Microsoft C/C+, Visual C++ for DOS & Windows 3.x Program:
(1) KEYPRO.OBJ: OBJ module for linking
(2) DEMO.C: DOS demo program for linking with KEYPRO.OBJ

1. How to use the linking module.

(1) Define KEYDATA as follow:

KeyPro API Function Codes:
#define KeyAPIReadMemory 0 /* Read memory */
#define KeyAPIWriteMemory 1 /* Write memory */
#define KeyAPISetPassword 2 /* Set password */

KeyPro API error codes:
#define APISuccess 0 /* Success */
#define APIAddressOverflow 1 /* Invalid address */
#define APIInvalidFunction 2 /* Invalid function */
#define APINoKeyPro 3 /* No KeyPro or password error */

KEYDATA Structure:
typedef struct {
unsigned short ReturnFlag; /* Return code */
unsigned short FunctionCode; /* Function code */
unsigned short MemAddress; /* Memory address */
unsigned short Password0; /* Access password */
unsigned short Password1;
unsigned short MemContent; /* Memory content for read&write */
unsigned short Lock0; /* New password to set */
unsigned short Lock1;
unsigned short Reserved[7]; /* Reserved for KeyPro, can't change! */
} KEYPRODATA;

(2) Define KEYPRO prototype and use it as follow:

In C program:
extern void far KEYPRO( KEYPRODATA far * );
In C++ program:
extern "C" void far KEYPRO( KEYPRODATA far * );

(3) Calling example:

KEYPRODATA *kd;
unsigned short Mem0;
kd->Password0 = 0;
kd->Password1 = 0;
kd->FunctionCode = KeyAPIReadMemory;
kd->MemAddress = 0;
KEYPRO( kd );
if( kd->ReturnCode == APISuccess ) Mem0 = kd->MemContent;


2. How to compile demo program and link it with linking module.

tcc demo.c keypro.obj ( Compile by Turbo C/C++ )
bcc demo.c keypro.obj ( Compile by Borland C++ )
qcl demo.c keypro.obj ( Compile by Quick C )
cl demo.c keypro.obj ( Compile by Microsoft C/C++ )

怎样加入结束其他任一程序进程的程序代码？（VC）

[windows_editor]

不知你的用途是什么 一般加密狗直接就提供了上述功能 不需要你程序中来进行判断 只要编译时在机器上插上加密狗 并在加密狗自己附带的软件中指定你要加密的程序就可以了

[wealth]

想独立成一个程序，然后做成一个服务在系统中自动运行，每隔一段时间检测密码，如不对，然后运用什么函数终止某一个程序！！！

如何做？

[wealth]

连字也懒得打了，上面的DEMO还没仔细看过！
