recursion - recursive function in c# get a parameter -

-

i'm trying parameter function...

public static int subsumer(string id,int acc,sqlconnection connection)  {     acc++;     sqlcommand cercas = new sqlcommand("select * common_relation id_source ='" + id + "' , type='@' ", connection);     sqldatareader leggsyn = null;     leggsyn = cercas.executereader();      int f = 0;     while (leggsyn.read())      {         f=  subsumer(leggsyn["id_target"].tostring(),acc,connection);         if (acc <= f)          {              acc = f;          }       }       //siamo arrivati alla fine     return acc-1; }

each cycle parameter acc increment , debugging see in case reach value 3, in final recursion 0...i can't it...thank all

by returning acc - 1, decrementing f returned recursive call , don't think that's expect.

public static int subsumer(string id,int acc,sqlconnection connection)  {     sqlcommand cercas = new sqlcommand("select * common_relation id_source ='" + id + "' , type='@' ", connection);     sqldatareader leggsyn = null;     leggsyn = cercas.executereader();      int f = 0;     while (leggsyn.read())      {         f=  subsumer(leggsyn["id_target"].tostring(),acc + 1,connection);         if (acc <= f)          {              acc = f;          }       }       //siamo arrivati alla fine     return acc; }

on side note, querying recursively isn't design choice. querying recursively readers open each call on stack worse. not using query parmeters bad thing.

-
i struggling on how find correct way specify save path (or repository) when calling function savefig in matplotlib or pylab. i tried several syntaxes, everytime python console returns : filenotfounderror: [errno 2] no such file or directory: '../mydocs/resource/frames/myimage.png' currently, have written following : pylab.savefig('../mydocs/resource/frames/myimage.png') does know how it? thanks in advance! the tilde operator , variable $home entered strings , therefore not function while saving. have provide either relative path (as did) or provide full path. eg. pylab.savefig("/home/username/desktop/myfig.png") .
