在PB中如何實現數據模糊查詢（二）

     屬性和代碼如下

     wroot_dw_query屬性

    X = Y = Width = Height =
    Visible = true Enabled = true TitleBar = true Title = 定位查詢
    ControlMenu = true Border = true WindowType = response! WindowState = normal!
    BackColor =

     窗口實例變量

    Boolean ib_changed
    Long MaxEditRow =
    String sWhere oldsql orisql is_title is_section = WhereClause
    DataWindow dw_resultdw_detail
    pfc_n_cst_string inv_string
    string sSyntax

    注釋apfc_n_cst_string 為PFC用戶對象

     窗口事件代碼

     close 事件

    功能將用戶本次所輸入的查詢條件記錄到文件sIniFile的WhereClausen小節中去以備下次啟動時置初始查詢條件

     open 事件

    功能設置初始值具體請看代碼中的注釋

    integer i row li_where_row =
    string tmp
    str_result_column lstr_
    //結構str_result_column的成員adw_result指查詢結果所產生作用的dw
