Quality Center Open Test Architecture API -OTA COM 9.0

Component Object Model (COM) is a software architecture that allows the components made by different software vendors to be combined into a variety of applications. COM defines a standard for component interoperability, is not dependent on any particular programming language, is available on multiple platforms, and is extensible.
It is used to enable inter-process communication and dynamic object creation in any programming language that supports the technology.
COM Automation allows users to build scripts in their applications to perform repetitive tasks or control one application from another.

The family of COM technologies includes

– COM+
– Distributed COM (DCOM) and
– ActiveX® Controls.



Quality Center Open Test Architecture API -OTA COM 9.0

The Quality Center Open Test Architecture API is a COM library that enables you to integrate external applications with Quality Center. It is naturally and easily used with Microsoft Visual Basic, and the syntax and examples in this reference use Visual Basic. The examples in this project were developed with Microsoft Visual Basic 6.0 and are not necessarily valid under other development platforms.
