Can Silk Performer"s DLL integration be used with VB based DLL files?

Can Silk Performer"s DLL integration be used with VB based DLL files?

DLL integration can not be used with VB.NET dlls. The reason for this is that those dll files do not make the Export Table available. Since a dll"s available methods are shown in it"s Export Table it is usually possible to query this table, for example when calling C++ dlls. As VB.NET dlls only make this table available to VB tools or .Net Framework it cannot be called from with Silk Performer BDL. To work with such DLL files the best method is to use the Silk Performer .Net Explorer to load the DLL and work with the methods and objects it exposes. This works because .Net Explorer uses the .Net Framework. For VB6 based dll"s it is possible to use the Silk Performer .Net Framework. This approach requires that your developer creates a VB COM class that implements the Silk Performer VB6 Testing Interface and using this we can access that class.



NOTE: Since the introduction of GUI-level testing in Silk Performer 2006 Release 2, it may be possible to loadtest applications that are not supported by Silk Performer on the protocol- or API-levels by recording on the GUI level. 

Please refer to the following video for an introduction to GUI-Level Testing in Silk Performer: Introduction to GUI-Level Testing
