pb中怎么获取数据窗口的列名
|
Getcolumn 得到的是当前powerobject的字段的数量。 调用语法: getcolumns ( powerobject apo_data, ref string as_columns[], ref string as_error ) Int li_colcount,i //取列数 Choose Case TypeOf(apo_data) Case datawindow! uo_datawindow_cics ldw ldw = apo_data li_colcount = Integer(ldw.Describe("DataWindow.Column.Count")) Case datawindowchild! datawindowchild ldwc ldwc = apo_data li_colcount = Integer(ldwc.Describe("DataWindow.Column.Count")) Case datastore! uo_datastore_cics lds lds = apo_data li_colcount = Integer(lds.Describe("DataWindow.Column.Count")) Case Else as_error = '调用GetColumns时入参错误：powerobject的类型不正确' Return -1 End Choose If Not li_colcount > 0 Then as_error = '取数据窗口的列数不成功！' Return -1 End If //取列名 String columnnames[],ls_colname For i = 1 To li_colcount Choose Case TypeOf(apo_data) Case datawindow! ls_colname = ldw.Describe("#" + String(i) +".Name") Case datawindowchild! ls_colname = ldwc.Describe("#" + String(i) +".Name") Case datastore! ls_colname = lds.Describe("#" + String(i) +".Name") End Choose
If IsNull(ls_colname) Or ls_colname = '?' Or ls_colname = '!' Then as_error = '调用GetColumns,取数据窗口的列名称不成功：'+String(i) Return -1 End If as_columns[i] = Upper(ls_colname) Next |
