How to add XProperties using the C++ interface

Summary

How to add XProperties using the C interface (VC ++).

Solution

  Cvdxyz p1,p2;
 p1.CreateDispatch("VDXYZ");
 p2.CreateDispatch("VDXYZ");
 p1.SetValueEx(1,2,3);
 p2.SetValueEx(4,5,6);

 CvdLine line = m_Vdraw.GetActiveDocument().GetActiveLayOutEntities().AddLine(COleVariant(p1.GetValue()),COleVariant(p2.GetValue()));

 CvdXProperties xprops = line.GetXProperties();

 //add a string type xproperty to xproperties collection of line object
 xprops.AddXProperty("property1",1000,COleVariant("mystring"));

 //add a point type xproperty to xproperties collection of line object
 xprops.AddXProperty("property2",1010,COleVariant(p1.GetValue()));

 //read xproperties
 CString name ,msg;
 long type;
 COleVariant value;
 for(int  i = 0 ; i < line.GetXProperties().GetCount();i++){
  name = line.GetXProperties().GetItem(i).GetName();
  type = line.GetXProperties().GetItem(i).GetType();
  value = line.GetXProperties().GetItem(i).GetValue();
  if(type == 1000){
   msg.Format("\n%s,%i,%s",name,type,CString(value.bstrVal));
   OutputDebugString(msg);
  }else if(type == 1010){
   p1.SetValue(value);< BR>   msg.Format("\n%s,%i, x=%f,y=%f,z=%f",name,type,p1.GetX(),p1.GetY(),p1.GetZ());
   OutputDebugString(msg);
  }
 }
