AttributeSetBinary Function

Action

Assigns binary data to a specified attribute of the user. The function automatically creates the attribute if it does not exist.

User attributes are useful when working with Silk Performer frameworks, in fact, when the user behavior is defined in two separate script. In that case, user attributes enable the exchange of data between scripts, for example, between a Silk Performer and a Java script.

Example

dcltrans
  transaction TMain
  var
    sString, sBuffer : string;
  begin
    AttributeSetString("name", "Jim");
    AttributeSetInt("age", 23);
    AttributeSetDouble("cash", 4503.60);
    AttributeSetBinary("code", "\h9EF30533");

    // do anything, for example, call an external function

    AttributeGetString("name", sString);
    writeln(sString);
    writeln(AttributeGetInt("age"));
    writeln(AttributeGetDouble("cash"));
    AttributeGetBinary("code", sBuffer);
    WriteData(sBuffer, STRING_COMPLETE);
  end TMain;
