Hi, I'm starting to learn VFP 5.0, using Visual MaxFrame Professional framework. I'm have some difficulties on when and where sub-class the original framework. I have to translate the framework to Portuguese. Let me give an example, I want to create a form based on a class called frmDEGridNav2Pages that has the following hierarchy : Form - Visual Foxpro base form class. frmBase - Visual MaxFrame base form class. frmData - Abstract class for modeless forms that manage data. frmDataEntry - Abstract class for (modeless) data-entry forms. frmDataEntrySCADO - Abstract class for modeless data entry forms, includes Save/Cancel and Print, Find, Add, Delete, OK commandbuttons. frmDEGridNav - Abstract class for data-entry forms, navigation is via an incremental-search grid. frmDEGridNav2Pages - Data-entry form with a search/navigation grid on page 1 of a pageframe. On frmDataEntrySCADO I have some buttons to Add/Delete and so on. I want to translate everything in these command buttons (sub-classing the original classes), create frmGCDEGridNav2Pages (sub-classed from frmDEGridNav2Pages). My problem now is how to change the class of the command button. I want to change from cmddataadd in X3FWCTRL.VCX to cmdgcdataadd in GCFWCTRL.VCX. Could I explain my problem ? Sorry for the bandwidth. TIA José Augusto Cavalcanti Global Connection jcavalcanti@ax.apc.org
