Konu: Bunu dener misiniz. Ben de mi acaba hata. VFP9 SP1'de cok yavas.
1) BufSpeedTest.prg olarak saklayin
2) Unbuffered test, bu hizli olmali. 0.5 - 0.7 saniye filan. Bilemedin 3 sn olsun/
Visual Fox Pro
BufSpeedTest()
3) Buffered test. Sorun burada. Daha 3 bolumun ilki bile bende 225 sn altina dusemedi. Kesmek icin ESC kullanabilirsiniz.
Visual Fox Pro
BufSpeedTest(.T.)
Insallah hata bendedir (sanki o zaman sevinicem:). VFP SP1 ile denedim ben.
