Cast a variant to a certain type


Source position: varianth.inc line 383

procedure VarCast(

  var dest: variant;

  const source: variant;

  vartype: LongInt



VarCast converts the variant in Source to the type indicated in VarType and returns the result in dest. The VarType must be one of the pre-defined VarNNN constants.


If the conversion is not possible because the value cannot be correctly casted, then a run-time error or an exception may occur.
