C++ InitWin函数代码示例

/*****************************
 *
 * Routines to create dialog items, all items have an id
 * which you can use to extract info. It is possible to have
 * multiple items with the same id but it may then not be possible
 * to extract information.
 * All routines take the position relative to the parent dlg
 * and the size and border width.
 * If the width and height are set to zero initially, they will
 * be calculated and set by the routine. With the dlgitem manipulation
 * routines listed below, the application can then move the items around
 * on the dlg box, and if wished resize them.
