深思4加密狗问题，懂的朋友麻烦帮帮忙，分少。。。谢谢

我在写S4，在用到它的API的S4Execute时候郁闷到了！先看看我的代码
下面是移植到狗里的代码：

#include "ses_v3.h"
void main()
{  char strOpenFail[50]="open Fail";
   char strReadFail[50]="read Fail";
   char outBuffer[50];
   HANDLE hfile;
   BYTE ret=0;
   ret=_open(0xa005,&hfile);
   if(ret!=SES_SUCCESS)
   {					    
      _set_response(sizeof(strOpenFail),strOpenFail);
	  _exit();
   }
   ret=_read(hfile,0,50,outBuffer);
   if(ret!=SES_SUCCESS)
   {
     _set_response(sizeof(strReadFail),strReadFail);
	 _exit();
   }
   _set_response(sizeof(outBuffer),outBuffer);
   _exit();
}

下面是C#里面的S4Execute操作：

private void btnConnectS4_Click(object sender, EventArgs e)
        {
            S4Open(ref s);
            uint ret;
            byte[] Pin = {	0x31,0x32, 0x33, 0x34, 0x35,0x36, 0x37, 0x38, 
								0x31,0x32, 0x33, 0x34, 0x35,0x36, 0x37, 0x38,
								0x31,0x32, 0x33, 0x34, 0x35,0x36, 0x37, 0x38};

            //verify dev PIN
            ret = S4VerifyPin(ref s, Pin, 24, S4_DEV_PIN);
            if (ret == 0x00) //SUCCESS 0x00  
            {
                MessageBox.Show("开发级权限验证成功");
            }

   
            uint ret1, BytesReturned = 0;
            byte[] inBuffer = Encoding.Default.GetBytes("");
            byte[] outBuffer = new byte[200];
            ret1 = S4Execute(ref s, "d001", inBuffer, (uint)inBuffer.Length, outBuffer, 200, ref BytesReturned);
            MessageBox.Show("返回码:" + ret.ToString() + "      返回长度:" + BytesReturned.ToString());
        }

我要实现的效果是：
点击PC程序写入文件（已实现，未贴出），然后由于SES才能读取文件，所以把代码植入狗内，运行SES系统函数_read,再把结果_set_response返回给pc，但是我S4Execute是执行成功了的，返回的是0，也就是ret是0，但是BytesReturned也是0（BytesReturned是返回的值的长度）。。。郁闷啊。写入狗内的是对了的，因为我用c来写是可以获取到的，
下面是c里面的代码（IDE：vc6.0）。

#include <stdlib.h>
#include <stdio.h>
#include <conio.h>
#include "sense4.h"

/*bubble sort function removed. Add EliteIV invoking code. */
void call_sense4(char *,char *, int);

/*main procedure*/
void main()
{
    char test[50]="";
	call_sense4("d001", test, 50);
	printf("%s\n",test);
}

void call_sense4(char *fid, unsigned char *buff, int len)
{
	SENSE4_CONTEXT ctx = {0};
	SENSE4_CONTEXT *pctx = NULL;
	unsigned long size = 0;
	unsigned long ret = 0;
	
	S4Enum(pctx, &size);
	if (size == 0)
	{
		printf("EliteIV not found!\n");
		
		return;
	}
	
	pctx = (SENSE4_CONTEXT *)malloc(size);
	if (pctx == NULL)
	{
		printf("Not enough memory!\n");
		return;
	}
	
	ret = S4Enum(pctx, &size);
	if (ret != S4_SUCCESS)
	{
		printf("Enumerate EliteIV error!\n");
		free(pctx);
		return;
	}
	
	memcpy(&ctx, pctx, sizeof(SENSE4_CONTEXT));
	free(pctx);
	pctx = NULL;
	
	ret = S4Open(&ctx);
	if (ret != S4_SUCCESS)
	{
		printf("Open EliteIV failed!\n");
		return;
	}
	
	ret = S4ChangeDir(&ctx, "\\");
	if (ret != S4_SUCCESS)
	{
		printf("No root directory found!\n");
		S4Close(&ctx);
		return;
	}
	
	ret = S4VerifyPin(&ctx, "12345678", 8, S4_USER_PIN);
	if (ret != S4_SUCCESS)
	{
		printf("Verify user PIN failed!\n");
		S4Close(&ctx);
		return;
	}
	
	ret = S4Execute(&ctx, fid, buff, len, buff, len, &size);
	if (ret != S4_SUCCESS)
	{
		printf("Execute EliteIV exe failed!\n");
		S4Close(&ctx);
		return;
	}
	
	S4Close(&ctx);
	
	return;
}

我无语了。。。这么多人都不理。。。好现实，分少也不理
