Visual studio shell 2010中跟踪当前选中的ToolWindow

Step1：在VSpakage中实现IVsSelectionEvents接口；

Step2：在Initiliaze初始话函数中注册之：

IVsMonitorSelection ms = Package.GetGlobalService(typeof(IVsMonitorSelection)) as IVsMonitorSelection

if(ms != null)

{

ms.AdviseSelectionEvents(this, out cookie);
}

Step3:重点实现OnElementValueChanged方法；

1、elementid = Microsoft.VisualStudio.Shell.Interop.Constants.SEID_WindowFrame;

2、if(varNewValue is IVsWindowFrame) actvieWindowFrame = varNewValue as IVsWindowFrame;

Step4：通过FindToolWindow，查找当前的ToolWindow，比对其Frame字段是否与activeWindowFrame相等，若相当，则为当前选中的ToolWindow
