Soru<\/b>:<\/p>\n

Windows’ta ShellExecute API’sini kullanarak harici programlar \u00e7al\u0131\u015ft\u0131rabiliyoruz. Ayn\u0131 i\u015flevi Linux ortam\u0131nda nas\u0131l yapabiliriz?<\/p>\n

Bu hafta Linux’u biraz kurcalayal\u0131m istedik, san\u0131r\u0131m biraz abartt\u0131k \ud83d\ude42<\/p>\n

Cevap<\/b><\/p>\n

Ya\u015fad\u0131\u011f\u0131m\u0131z problemin iki aya\u011f\u0131 vard\u0131;<\/p>\n

Bunlardan birincisi _PAnsiChar tipinin NEXTGEN derleyici direktifi kapsam\u0131nda tan\u0131ml\u0131 olmas\u0131ndan kaynaklan\u0131yordu, yani LINUX, LINUX64 gibi derleyici direktifleri alt\u0131nda do\u011frudan bir tip tan\u0131mlamas\u0131 ile kar\u015f\u0131la\u015famad\u0131m. Bu sorunu a\u015fmak i\u00e7in Type Casting tekni\u011fini kulland\u0131m ve sorunumu bu noktada \u00e7\u00f6zm\u00fc\u015f oldum. Yani PUTF8Char( RawByteString( filename ) )<\/b> tip sarmalamas\u0131yla bu noktay\u0131 a\u015fm\u0131\u015f olduk.<\/p>\n

Fakat yine de s\u00f6z konusu klas\u00f6r\u00fc bir pencerede g\u00f6sterme sorununu a\u015fmak gerekiyordu. Bu sorunu a\u015fmak i\u00e7in linux’ta bu i\u015fler i\u00e7in “xdg-open”<\/b> komutunun kullan\u0131lmas\u0131 gerekiyor. Bu komut t\u0131pk\u0131 Windows’daki gibi ShellExecute<\/strong>‘nin yapt\u0131\u011f\u0131 i\u015fi konsolda bir komut olarak yerine getiriyor. Sadece bir klas\u00f6r\u00fc a\u00e7mak i\u00e7in de\u011fil, ayn\u0131 zamanda i\u015fletim sisteminin tan\u0131d\u0131\u011f\u0131 dosya tiplerine kar\u015f\u0131l\u0131k gelen ilgili program\u0131 \u00e7a\u011f\u0131rarak dosyalar\u0131 da a\u00e7abiliyor veya bir URL yazd\u0131ysan\u0131z onu browser’a da y\u00fckleyebiliyor…<\/p>\n

Detayl\u0131 bilgi i\u00e7in a\u015fa\u011f\u0131daki linke bak\u0131labilir.<\/p>\n

Sonu\u00e7 olarak hem Windows’ta hem de Linux’ta \u00e7al\u0131\u015fan bir program olmu\u015f oldu;<\/p>\n
