COMslicer helps to develop reliable COM components and ActiveX controls (ActiveX is a technology built on COM). It traces all run time calls to selected COM objects. COMslicer displays values of input and output parameters for each method or properties being called by the client. It also displays such events as creating/destroying of COM objects and loading/unloading of DLLs that contain selected COM components. Debugging and testing of COM components with COMslicer facilitates resolving of problems that cannot be traced in a static debugger environment. In a real word run time environment COM components can be exploited in a way that is unexpected for developers. Observing the behavior of COM objects allows to realize sources of errors or potential problems. COMslicer can trace COM components written in VC++, VB or VJ++ languages. A developer's efforts are not needed to use COMslicer - it does not require inserting any additional code into the source code or building a debug version of COM component. COMslicer uses only type library information that is usually automatically included into DLL that contains COM component.
Main features of COMslicer:
- COMslicer displays all calls made by client(s) to selected COM objects in real time;
- COMslicer's Explorer-like user interface allows browsing of displayed trace;
- COMslicer keeps track of COM objects' referencing and creates report about used interfaces after objects are destroyed;
- COMslicer can trace COM components written in any language with no efforts required from the developer.
