1 judul : dump mysql with delphi - opensource header : hmm...ini sebenernya dah pernah tak tanyain dalam thread tapi lom ada jawaban yang memuaskan, aq coba ekplor terus dan akhirnya 3 bulan yang lalu bisa juga buatnya, disini aq akan membagikan ilmu yang aq dapat yaitu cara untuk melakukan dumping database mysql. body : setelah aq modifikasi dengan perubahan kode2 yang lebih sederhana semoga contoh tool ini dapat dipelajari dengan mudah (kalo masih sulit maap ya :)) ini dia screenshotnya : untuk artikel ini aq hanya memberikan contoh cara untuk dump mysql, untuk restorenya...hmm...di artikel yang lain ya..:) (eksplor dulu siri), seperti biasanya aq gak terima kritikan,saran apalagi bug dalam program ini karena program ini hanyalah sekedar bagi-bagi ilmu doank dan kalo ada bug ya perbaiki siri ya :), berikut ini listing program selengkapnya dari ubackup.pas : <code> unit ubackup; interface uses windows, messages, sysutils, iants, classes, graphics, controls, forms, dialogs, extctrls, stdctrls, zsqlprocessor, db, zabstractrodataset, zabstractdataset, zdataset, zconnection,clipbrd; type tfbackup = class(tform) panel1: tpanel; panel2: tpanel; label1: tlabel; label2: tlabel; label3: tlabel; edserver: tedit; eduser: tedit; edpass: tedit; label4: tlabel; cbdb: tcombobox; panel3: tpanel; panel4: tpanel; dbcreate: tcheckbox; tbcreate: tcheckbox; datacreate: tcheckbox; panel5: tpanel; button1: tbutton; dbkonek: tzconnection; q1: tzquery; procedure cbdbdropdown(ser: tobject); procedure button1click(ser: tobject); procedure tbcreateclick(ser: tobject); private procedure connectdb; procedure scriptsql(_sql: string ; issearch: boolean); //procedure per-module
