Development Note

When changing the version, update the files hb_el.ch, hb_el.prg (el_GetVersion()).

Function List

  • el_DateTime([nYear],[nMonth],[nDay],[nHour],[nMinute],[nSecond],[nFragment]) - Similar to hb_DateTime but with no milliseconds
    hb_DateTime([nYear],[nMonth],[nDay],[nHour],[nMinute],[nSecond],[nFragment]) ➔ Returns a timestamp value from the supplied day, month, year, hour, minute, second values and ignores nfragment. If none of them is supplied, the current date and time is returned.

  • el_Seek(xExpression [, nWorkArea | cTableAlias [, nIndexNumber | cIDXIndexFileName | cTagName]]) -> lFound

  • el_Between(xExpression,xLowValue,xHighValue) -> lResult
    True if xExpression >= xLowValue and eExpression <= xHighValue

  • el_StrToFile(cExpression,cPathAndFileName,lAdditive) -> nBytesWritten
    Write the cExpression to file located at cPathAndFileName. Will overwrite the file unless lAdditive is true.

  • el_dbf(nWorkArea | cTableAlias) -> cTableName
    Returns the name of a table open in a specified work area or a table name from a table alias. Not the entire file path.

  • el_InlistPos(xExpression,xExpression1 ... xExpressionx) -> nPosition
    nPosition will retun 0 of xExpression is not any of the following expressions, or a value 1 to x to represent which expression is a match.

  • el_IsInlist(xExpression,xExpression1 ... xExpressionx) -> lResult
    Return true if xExpression is any of the following parameters

  • el_StrReplace(cString,cSource|acSource|hReplace,[cDest|acDest]) -> cResult
    Case insensitive ready version of hb_StrReplace

  • el_StrTran(cSearched,cExpressionSought,cReplacement,[nStart],[nCount],[nFlags])
    If nFlags is -1 the search and replace are case insensitive.

  • el_GetProcessID() -> iProcessID
    Returns a Process ID. Only implemented for MS Windows and Linux

  • EL_GetVersion() -> nVersion. A Numeric with decimals representing the library version number.

  • el_SendToDebugView(cMessage,[xValue]) -> .t.
    Will send to debugview a message cMessage if xValue is missing and cMessage+xValue(converted to text) if xValue is present.

  • hb_el_buildinfo() -> Text
    Returns build information like the C compiler used and a timestamp

  • el_AddPs(cPath) -> cPath Add trailing Path Separator if missing, as long as cPath is not empty (Equivalent to VFP AddBs())

Precompiler Instructions

Review hb_el.ch for entire list.
On of the most practical addition is the "scan / endscan" which was inspired by VFP.
