CMFCPropertyGridCtrl的属性改变事件代码

//用于区分Prop， 使用SetData， GetData方法

CMFCPropertyGridProperty* pProp1 = new CMFCPropertyGridProperty(strTitle, (_variant_t)bVal, strDesc);

pProp1->SetData(100);

int nPropId = pProp1->GetData();

//声明消息处理函数

afx_msg LRESULT OnPropertyChanged( WPARAM wParam,LPARAM lParam );

//注册消息， AFX_WM_PROPERTY_CHANGED：发送ctrl消息到父窗口

BEGIN_MESSAGE_MAP(CMyWnd, CWnd)
 ON_WM_PAINT()
 ON_WM_CREATE()
 ON_REGISTERED_MESSAGE(AFX_WM_PROPERTY_CHANGED, OnPropertyChanged)
END_MESSAGE_MAP()

//消息处理， lParam是Property属性项， wParam是ctrl的id

LRESULT CMyWnd::OnPropertyChanged( WPARAM wParam,LPARAM lParam )
{
 CMFCPropertyGridProperty* pProp = (CMFCPropertyGridProperty*) lParam;

//is the property ctrl
 if ( (long)wParam == 2 )
 {
  
 }

pProp->SetValue((_variant_t)false);
 pProp->Redraw();
 int pID = pProp->GetData();
 CString str = pProp->GetName();
 if ( str == _T("abc") )

  COleVariant var = pProp->GetValue();
  if ( var.boolVal == VARIANT_TRUE )
  {
  // AfxMessageBox(L"failed!");
   
   //pProp->SetValue(VARIANT_FALSE);
  }
 }

if  (pID == 1)
 {
