Hello,
I have the following problem. I have written a class in PowerBasic where I need Optional parameters in methods. Whom do I want to build the whole thing with compilers compile and Com-browser with an include file is optional in the parameter list off every time I need to write it purely by hand.
Example:
#COMPILER PBWIN 9
#COMPILE DLL
#RESOURCE "TestClass.pbr"
#DIM ALL
#COM NAME "TestClass", 1
#COM DOC "List of TestClass"
#COM TLIB ON
$CTestClass = GUID$("{1A856B38-0C99-43ED-BF8E-D7BD981261E4}")
$ITestClass = GUID$("{7C401253-58F2-4654-B570-3A0240E405C1}")
CLASS CTestClass $CTestClass AS COM
INTERFACE ITestGlass $ITestClass
INHERIT IDISPATCH
PROPERTY GET Definition( OPTIONAL w AS VARIANT) AS STRING
END PROPERTY
END INTERFACE
END CLASS
Code of the browser creates Com. as we see is an optional away and must be re-written by hand are strictly

The ICreateTypelib interface, used to create type libraries automatically, doesn't support optional parameters. You may need to build the type library using the MIDL compiler.
Hello Jose,
This is too complicated for me ???. I have now searched two days after MIDL compiler. What do I know the PowerBASIC is optional but supported enters not into the Typelieb. So what we made so I would write a program that reads the Source and the OPTION fits into the include file.
