Most Windows programmer already know about the API OutputDebugString.
But with Cincom Smalltalk you can combine the power of OutputDebugString with the power of MethodWrappers.

What are MethodWrappers?

MethodWrapper is a class, which wraps compiled methods in other classes.
Each subclass of MethodWrapper does something specific and my subclass calls OutputDebugString with the receiver, the selector and the arguments. These calls can be made visible by a tool like DebugView, which can be downloaded for free.

But what’s the advantage to just writing a log file?
Well, first of all, you can follow the output live, while testing your system.
Second, you could enable (install) those wrappers at your deployed image, use DebugView to connect to the computer and diagnose the system at runtime.

Sometimes that saves you hours of going back and forth with the end-user.

You can find the parcel in the public Store repository, called “OutputDebugPackage”.
