Kieker4COM VB6 Aspects Project

The Kieker4COM aspects project directory for VB6 can be found in the directory src/vb6/Kieker4COM_aspects. The VB6 project file, which can be imported into the Visual Basic 6 IDE and can be used with Aspect VB6, is src/vb6/Kieker4COM_aspects/Aspects.vbp.

Currently, the project includes two aspects for monitoring executions (OpExecIcptr) and calls (OpCallIcptr) of VB6 routines, i.e., Procedures, Functions, and Properties:

1. OpExecIcptr.cls

2. OpCallIcptr.cls

Using the Kieker4COM Aspects

The directory Kieker4COM\examples\vb6\bookstore-annotated contains a VB6 version of the Bookstore application, including annotations for the Kieker4COM aspects. These annotations can be processed by Aspect VB6.

Adding Annotations to VB6 Source Code

The examples were taken from the KiekerCOM example project Kieker4COM\examples\vb6\bookstore-annotated.

OpExecIcptr

'@intercept#Execution:OpExecIcptr["Bookstore","Class_Initialize"]

Private Sub Class_Initialize()

Set oCatalog = New catalog

...

OpCallIcptr

Public Sub searchBook()

'@intercept#Call:OpCallIcptr["Bookstore", "searchBook", "Catalog", "getBook"]

catalog.getBook (False)

'@intercept#Call:OpCallIcptr["Bookstore", "searchBook", "CRM", "getOffers"]

crm().getOffers

End Sub
