中国移动飞信的研究 笔记二

中国移动飞信的研究 笔记二

经过 上一篇 的查看飞信 里面 封装了不少。 这里面不仅是一层加一层，而且是这一层还调用另外的程序集。类与类之间的组合、继承可谓是 很复杂。到底从哪里下手呢。 我本次研究 也不是为了彻底的研究它，也就是他的一些基本功能的研究。顺便，将一些类弄清楚。最后还是按照程序的 运行顺序一步一步的来研究吧。按照功能分析。

 

声明：个人并非侵犯 移动公司的权益。此笔记纯属个人学习的记录。若移动不同意，我立马将这些文档删除！希望各位见谅！

 

下面就将程序的包含主函数的Program 发出来：

 

namespace Imps.Client.Pc

{

using System;

using System.Net;

using System.Runtime.InteropServices;

using System.Threading;

using System.Windows.Forms;

internal static class Program

{

private const int BUFSIZE = 0x3e8;

private const int TOKEN_ADJUST_PRIVILEGES = 0x20;

private const int TOKEN_QUERY = 8;

[DllImport("kernel32.dll", ExactSpelling=true)]

internal static extern IntPtr GetCurrentProcess();

[DllImport("advapi32", CharSet=CharSet.Auto)]

private static extern bool GetTokenInformation(IntPtr hToken, TOKEN_INFORMATION_CLASS tokenInfoClass, IntPtr TokenInformation, int tokeInfoLength, ref int reqLength);

[STAThread]

private static void Main(string[] args)

{

Thread.CurrentThread.Name = "Imps.Client.Pc MainThread";

Application.EnableVisualStyles();

ServicePointManager.MaxServicePointIdleTime = 0x7530;

try

{

IntPtr currentProcess = GetCurrentProcess();

IntPtr zero = IntPtr.Zero;

if (!OpenProcessToken(currentProcess, 40, ref zero))

{

goto Label_008C;

}

IntPtr tokenInformation = Marshal.AllocHGlobal(0x3e8);

int tokeInfoLength = 0x3e8;

GetTokenInformation(zero, TOKEN_INFORMATION_CLASS.TokenPrivileges, tokenInformation, tokeInfoLength, ref tokeInfoLength);

TokPriv1Luid luid = (TokPriv1Luid) Marshal.PtrToStructure(tokenInformation, typeof(TokPriv1Luid));

if (luid.Count > 1)

{

goto Label_008C;

}

MessageBox.Show("运行此程序的权限不够！");

}

catch

{

}

return;

Label_008C:

Application.SetCompatibleTextRenderingDefault(false);

Application.Run(new MainForm(args));

}

[DllImport("advapi32.dll", SetLastError=true, ExactSpelling=true)]

internal static extern bool OpenProcessToken(IntPtr h, int acc, ref IntPtr phtok);

private enum TOKEN_INFORMATION_CLASS

{

TokenDefaultDacl = 6,

TokenGroups = 2,

TokenImpersonationLevel = 9,

TokenOwner = 4,

TokenPrimaryGroup = 5,

TokenPrivileges = 3,

TokenRestrictedSids = 11,

TokenSessionId = 12,

TokenSource = 7,

TokenStatistics = 10,

TokenType = 8,

TokenUser = 1

}

[StructLayout(LayoutKind.Sequential, Pack=1)]

internal struct TokPriv1Luid

{

public int Count;

public long Luid;

public int Attr;

}

}

}

  

此程序里引用了 Windows的API。

引用这些API 据我 查看应该是 保证程序有足够的 权限来运行！

由 Application.Run(new MainForm(args)); 可以看出，首先是调用了主界面 MainForm。

其中，args 为传递过来的参数。

下面是 MainForm的源代码: 由于程序源代码多大 3200多行，IE打开会很慢，所以只列出重要代码!

}

ImpsHelp.HelpPage = Imps.Client.Core.FixedClientSetting.Instance.HelpPage;

this.CurHandleRef = new HandleRef(this, base.Handle);

this.RegWndMsg();

}

catch (Exception exception)

{

MessageBox.Show(exception.Message);

ShellHelper.ApplicationExit();

}

}

}

...

...

}

}

 

            if (this.TryCheckSingleton())

            {

                CallMeHelper.TrySendCallMeMessage(args, base.Handle);

                Environment.Exit(0);

            }

            else

            {

                if (this.ExistFetionInstance())

                {

                    if (CallMeHelper.TrySendCallMeMessage(args, base.Handle))

                    {

                        Environment.Exit(0);

                        return;

                    }

                }

这里可以看出 飞信程序一台机器只能登陆一个。保证了程序的唯一性。

 

由于主界面里功能很复杂，篇幅太长这里就不解释了。
