Hi,
   Following your "how to develop a new car-following model" , I have
   developed a new car-following models 
http://www.sumo.dlr.de/wiki/Developer/How_To/Car-Following_Model

but when i use the model in file rou.xml , execute by sumo-gui :

Error: Unknown cfmodel  when parsing vtype 'xxxx'
Quitting (on error).

because i didn't find file in this :
Add the files  to the MSVC10 project located in <SUMO_HOME>/build/msvc10/y_libmicrosim. 
 if i open the two file i didn't find any cfmodel (like IDM..)

please help me 
thanks
