【详细过程】
破解DotNetBar 7.2.0.6 for Windows Forms 控件
以前总来看雪学院，总是潜水学习，写过一点破解记录，也总是在低水平徘徊，不敢拿来献丑。后
来学做别的，离开这里很久了，最近在编程时看到DotNetBar控件，就拿来练手。水平有限，高手笑略。
DotNetBar是DotNet平台上的界面控件包，极大地丰富了VS2003、2005的程序界面，包含最新的
Office 2007的样式的控件组，Vista样式的BubbleBar。最近出了v7.2.0.6全功能试用版,试破之。
试用限制：试用时间：33天；某些组件启动时会有试用提示框，几秒钟后激活“OK”按钮，点击后
方可继续；某些控件标题栏会有“Trail”字样。
破解目标：解除各试用限制。
用Reflector载入，（这真是个好工具啊），首先找它提示试用的字符“Trail”，找到了三个地方
，
DevComponents.DotNetBar.Bar.OnPaint(PaintEventArgs) : Void
DevComponents.DotNetBar.ItemControl.PaintControl(ItemPaintArgs) : Void
DevComponents.DotNetBar.RibbonStrip.PaintControlBackground(ItemPaintArgs) : Void
进入DevComponents.DotNetBar.RibbonStrip.PaintControlBackground(ItemPaintArgs) : Void
看到
if (1Z.0RB())
{
pa.Graphics.Clear(Color.White);
59.1HQ(pa.Graphics, "Trial Version Expired", this.Font, Color.FromArgb(0x80,
Color.Black), base.ClientRectangle, eTextFormat.VerticalCenter |
eTextFormat.HorizontalCenter);
}
else
{
59.1HQ(pa.Graphics, "Trial Version", this.Font, Color.FromArgb(0x80, Color.Black),
base.ClientRectangle, eTextFormat.Right);
}
即在标题上绘制"Trial Version Expired"和"Trial Version"字符串的地方。其他两处也引用了同样的
判断过程。
先切进PaintControlBackground方法，在Xenocode Fox 2007中看到地址Method Body Address:
0x0011B754
转为IL：

[System.Drawing]System.Drawing.Color, valuetype [System.Drawing]System.Drawing.Rectangle,
valuetype DevComponents.DotNetBar.eTextFormat)
L_018a: ret
用UltraEdit打开，定位到11B8BE，此处和计算所得并不相同，向后推移了12个字节，不知是不是程序
增加了一些偏移。好在用Reflector可以看到代码的十六进制形式，向后推，很快就可以到对应的位置。
将15E到18A前一个字节共44字节的内容换为00。试用版的提示字符就不再存在了。
跟进1Z.0RB（），是如下代码：
internal static bool 0RB()
{
Color control = SystemColors.Control;
control.ToArgb();
control.ToArgb();
if (!42G.IsEmpty)
{
return !(42G == Color.Black);
}
try
{
RegistryKey classesRoot = Registry.ClassesRoot;
try
{
classesRoot = classesRoot.CreateSubKey(@"CLSID\{BC469E31-CD88-442c-8BB2-
A1EBD6B44AB1}\InprocServer32");
}
catch (UnauthorizedAccessException)
{
classesRoot = classesRoot.OpenSubKey(@"CLSID\{BC469E31-CD88-442c-8BB2-
A1EBD6B44AB1}\InprocServer32");
}
try
{
if ((classesRoot.GetValue("") == null) || (classesRoot.GetValue("").ToString()
== ""))
{
classesRoot.SetValue("", DateTime.Today.ToOADate().ToString());
}
else
{
if (classesRoot.GetValue("").ToString() == "windows3.dll")
{
42G = Color.White;
classesRoot.Close();
classesRoot = null;
return true;
}
DateTime time = DateTime.FromOADate(double.Parse(classesRoot.GetValue
("").ToString()));
if (DateTime.Today.Subtract(time).TotalDays > 21.0) // 判断是否
过期
{
42G = Color.White;
classesRoot.SetValue("", "windows4.dll");
classesRoot.Close();
classesRoot = null;
return true;
}
if (DateTime.Today.Subtract(time).TotalDays < 0.0) // 判断是否
过期
{
42G = Color.White;
classesRoot.SetValue("", "windows3.dll");
classesRoot.Close();
classesRoot = null;
return true;
}
}
}
finally
{
if (classesRoot != null)
{
classesRoot.Close();
}
42H = true;
}
}
catch
{
}
42G = Color.Black;
return false;
}
返回false可以运行，42G的颜色为Color.Black，返回true就是前后过期了，且颜色为Color.White，
有三个这样的地方。

在Xenocode Fox 2007中看到此段代码地址为：// Method Body Address: 0x000DB0A4
用UltraEdit打开，依次定位到各地址，再向后找12字节，修改前三次取色的call字节“28 99 00 00
0A”为“28 F1 02 00 0A”，三个返回“true”的字节“17”为“16”。保存。
替换原文件，更改系统日期，发现时间限制已经去除。
根据启动对话框中的文字，查到启动对话框是“2T”，引用的地方如下：
DevComponents.DotNetBar.2T

展开DevComponents.DotNetBar.DevCoLicenseProvider.GetLicense(LicenseContext, Type, Object,
Boolean) : License
此处在Xenocode中看不到，实际上还有许多的地方均显示为“Invalid string heap index”，估计是
程序采取了一些混淆处理，好在一个一个展开，也用不了太长时间，就可以看到“GetLicense”这句了。
此处代码如下：
public override License GetLicense(LicenseContext context, Type type, object instance,
bool allowExceptions)
{
0Z z = null;
if (context != null)
{
z = new 0Z("");
if (context.UsageMode == LicenseUsageMode.Runtime)
{
new 2T().ShowDialog(); //此句置0
}
else
{
context.SetSavedLicenseKey(type, z.LicenseKey);
}
}
if ((z == null) && (context != null))
{
new 2T().ShowDialog(); //此句置0
z = new 0Z("");
}
return z;
}
IL格式如下：

展开DevComponents.DotNetBar.SideBar..ctor()
// Method Body Address: 0x0012A0A4
IL格式如下：
L_00e9: newobj instance void DevComponents.DotNetBar.2T::.ctor() //此处开
始置0共13字节
L_00ee: stloc.0
L_00ef: ldloc.0
L_00f0: callvirt instance [System.Windows.Forms]System.Windows.Forms.DialogResult
[System.Windows.Forms]System.Windows.Forms.Form::ShowDialog()
L_00f5: pop
去掉SideBar控件的启动框。
展开DevComponents.DotNetBar.Wizard.OnHandleCreated(EventArgs) : Void
// Method Body Address: 0x00159600
IL格式如下：
L_0007: newobj instance void DevComponents.DotNetBar.2T::.ctor() // 此处开
始置0共19字节
L_000c: stloc.0
L_000d: ldloc.0
L_000e: callvirt instance valuetype [System.Windows.Forms]
System.Windows.Forms.DialogResult [System.Windows.Forms]
System.Windows.Forms.Form::ShowDialog()
L_0013: pop
L_0014: ldloc.0
L_0015: callvirt instance void [System]System.ComponentModel.Component::Dispose()
总结：去掉new 2T().ShowDialog();形式的框要置0共13字节。
去掉2T t = new 2T();
t.ShowDialog();
t.Dispose();形式的框要置0共19字节。
修改系统日期，并逐条试用自带的Demo，运行正常。完成。
