CollectionClasses and iterating a List

john2 — Thu, 25 Sep 2008 21:33:23 +0000

Hey Thomas, can you take a look at this and tell me if this is how you intended for iteration through a List to be done? The objects symbols and childScopes are List objects.

  METHOD PUBLIC VOID addSymbolsDeep(TABLE symbolRecord BIND):
    DEF VAR symbol AS CLASS Symbol NO-UNDO.
    symbols:getNthElement(0).
    DO WHILE symbols:hasNextElement():
      symbol = CAST(symbols:nextElement(), Symbol).
      CREATE symbolRecord.
      ASSIGN
          symbolRecord.symbol = symbol
          symbolRecord.progressType = symbol:getProgressType()
          .

Reflection API in Progress 4GL

Hello! In our application we need some classes to be created only once. I will implement these classes as singletons (with the help of the static keyword in 10.1.C)

METHOD PUBLIC STATIC CLASS CLSBETaskUserBase getInstance(): IF NOT VALID-OBJECT (clsBEModel) THEN clsBEModel = NEW CLSBETaskUserBase(). RETURN CAST (clsBEModel, CLSBETaskUserBase). END METHOD.

Accessing global/shared variables inside a class

h_kos — Wed, 19 Dec 2007 09:26:21 +0000

Hello!

I try to refactor an existing source i.e. make a class out of it.
The problem is that the existing source accesses (and changes) global shared variables.

When I create a class and want to reuse the existing code I get a problem because shared entities cannot be defined inside a class or interface. How can I access and change these global shared variables inside my class?

I want to use odbc_connect() to connect my 10.1B Progress OE database. I am getting "Can't open lib '/progress/dlc/odbc/lib/pgoe1022.sl'" error. The database server and apache are all on the same server HP-UX. Anybody had this working?

thanks,
