Limitations and Differences for Calling Functions

  • GetValue

    The column argument works only if the edit style of the column is CheckBox, DropDownListBox, Edit, or RadioButton.

  • GetSQLSelect

    If the syntax in DataWindow is PBSELECT statement, when calling the GetSQLSelect function, it will still return the PBSELECT statement but not the SQL SELECT statement, which is different from that in PowerBuilder.

  • ImportFile, ImportString, ImportClipboard

    1. The filename argument of ImportFile function must be a tab-separated file (TXT) or a comma-separated file (CSV).

    2. The string argument of ImportString function must be a tab-separated string (text).

    3. The importtype arguments (e.g. Text!, CSV! and XML!) of ImportString function are unsupported.

      The importtype arguments (e.g. Text!, CSV!, XML!, DBase2!, DBase3!) of ImportFile function are unsupported.

    4. When using the three functions, you should ensure that the data type imported matches the data type that you specified in a DataWindow control, DataStore object or graph control. Otherwise the output on the Web may be different from that in PowerBuilder. For example, if the date type specified in a DataWindow is string, when you import a file with date number (eg, 2006-08-01), on the Web the date data will be recognized as a string (2006), however in PowerBuilder, it will be recognized as a date data (2006-08-01).

  • Modify

    If the Modify function is used to modify the WHERE clause of the DataWindow object's SQL SELECT statement, please make sure that the new SQL SELECT statement is correct in syntax. Otherwise, syntax errors can occur on the Web because PowerBuilder does not validate the statement whereas JavaScript does.

    In Appeon Web, the Modify function cannot be used to modify the database information.

  • RowsMove

    Events cannot be triggered while the application moves data within the primary buffer of one DataWindow.

  • SaveAs

    1. The saveastype argument can be TEXT, HTMLTable, WMF (EAServer only), XML, PDF*, EXCEL, or EXCEL5. For the EXCEL format, only up to 256 characters are supported and anything larger will be automatically truncated.

    2. The supported SaveAs syntax:

      ll_testvalue = ds_test.SaveAs(filename, saveastype, colheading, encoding)

      SaveAs PDF cannot support the colheading argument, for example, the following syntax is unsupported: 

      integer ds_test.SaveAs ({string filename, saveastype saveastype, boolean colheading {, encoding encoding}})

      The unsupported SaveAs syntax:

      ds_test.SaveAs ([filename, ]graphcontrol[, saveastype, colheading])

    3. On the Web, Nillable attribute is unsupported in an XML schema.

    4. If the DataStore without any data is saved as an HTML file or XML file, on Web the header will not be saved, whereas it will be saved on PB.

    5. The generated file is automatically saved to the "plugin" folder under the current application directory. See "plugin" folder in Workarounds & APIs Guide for more.

  • SaveAsAscii

    Retainnewlinechar argument is unsupported.

  • SetValue

    The column argument works only if the edit style of the column is DropdownListBox.

  • SetSort

    Using "desc" or "asc" as the Order will not have any effect. Please use the standard Order value A for ascending or D for descending order.

  • TriggerEvent

    The following TriggerEvent syntax is unsupported:

    object1.TriggerEvent (object2, event)
Prev  Up  Next
Events of DataStore object  Home  DataWindowChild object
