report.autoseachfields[n].value

edited June 2004 in End User
Hi,
The AutoSearchField[0] is a DateTime field. I'm getting a RAP run-time error
when I try this:

FormatDateTime('mm/dd/yyyy',report.autosearchFields[0].value)+'''';

or this:

FormatDateTime('mm/dd/yyyy',StrToDate(report.autosearchFields[0].value))+'''
';

What could be wrong ?

Thanks in advance,

    Try using AutoSearField.SearchExpression. That propery contains the date
    entered by the user. Note: the SearchExpression property is a string.

    The string entered by the user is converted using Delphi's StrToDateTime. By
    default Delphi's StrToDateTime relies on the date formatting variables for
    the current windows locale. These can be overridden by the developer. See
    Delphi online help for StrToDateTime for more information.

    If you are using DADE, the following may also be helpful to you:


    -------------------------------------------------
    Tech Tip: Date formats used by DADE
    -------------------------------------------------

    DADE handles in two phases:


    1. User entry

    This occurs when the user specifies a date using the Query tools or the
    AutoSearch dialog. DADE converts the date string entered by the user into a
    Delphi TDateTime value. The string entered by the user is converted using
    Delphi's StrToDateTime. By default Delphi's StrToDateTime relies on the date
    formatting variables for the current windows locale. These can be overridden
    by the developer. See Delphi online help for StrToDateTime for more
    information.


    2. SQL submitted to the server

    When generating the SQL to be submitted to the database server, DADE
    converts the TDateTime value from number 1 above, to a string using the
    Delphi's FormatDateTime function. The format string used to convert the
    TDateTime is specified by the TdaSession.GetSearchCriteriaDateFormat and
    TdaSession.GetSearchCriteriaTimeFormat functions. These are virtual methods
    which may be overridden by descendant TdaSession classes.

    Below are the default values returned.


    {---------------------------------------------------------------------------
    ---}
    { TdaSession.GetSearchCriteriaDateFormat }

    function TdaSession.GetSearchCriteriaDateFormat(aDatabaseType:
    TppDatabaseType; const aDatabaseName: String): String;
    begin

    {return a format usable by FormatDate}
    case aDatabaseType of

    dtMSAccess:
    Result := 'YYYY-MM-DD';

    dtMSSQLServer, dtSybaseASA, dtSybaseASE, dtOracle:
    Result := 'YYYY/MM/DD';

    dtAdvantage:
    Result := 'YYYY-MM-DD';

    else
    Result := 'MM/DD/YYYY';

    end;

    end; {function, GetSearchCriteriaDateFormat}

    {---------------------------------------------------------------------------
    ---}
    { TdaSession.GetSearchCriteriaTimeFormat }

    function TdaSession.GetSearchCriteriaTimeFormat(aDatabaseType:
    TppDatabaseType; const aDatabaseName: String): String;
    begin
    {return a format usable by FormatDateTime}
    case aDatabaseType of

    dtMSAccess:
    Result := 'HH::MM::SS';

    else
    Result := 'HH:MM:SS';
    end;

    end; {function, GetSearchCriteriaTimeFormat}



    Note: DADE augments the above with additional formatting delimiters for
    Oracle and MSAccess. See TdaSQL.ResolveCriteria located in
    RBuilder\Source\daSQL.pas for more information.
