Kosta,

Your three questions are very different. You would do better to post them in separate threads.

I'll answer the first only. Assuming your combo has "All", "Male" and "Female".

cSQLStatement = ;
  [SELECT * FROM okul2 ] + ;
  [WHERE ] + ; 
  IIF(thisform.Combo1.value = "All", [.T. ], ;
  IIF(thisform.Combo1.value = "Male", [okul2.sex = "M" ], ;  
  [okul2.sex = "F" ])) + ; 
  [and okul2.ilce=thisform.Combo2.value ] + ;
  [and okul2.okul=thisform.Combo3.value ] + ;
  [and okul2.ozur=thisform.Combo4.value ] + ;
  [and okul2.zeka=thisform.Combo5.value ] + ;
  [and okul2.onlem=thisform.Combo6.value ] + ;
  [and okul2.devam=thisform.Combo7.value ] + ;
  [and okul2.iq>=thisform.Text1.value ] + ;
  [and okul2.iq<=thisform.Text2.value ] + ;
  [into cursor crsResult NOFILTER ]

Please note that square brackets are string delimiters in FoxPro. They really help in situations like this where you have internal quotes as well.
