MSVC's debugger displays ROOT's objects

Hi,

for the windows users using win32(gdk), and debugging stuff with the MS Dev Studio:

I always assumed that there must be a trick, and I finally found it. It’s kinda hard to tell whether this is well known or not, so here it goes: the file
C:\Program Files\Microsoft Visual Studio .NET\Common7\Packages\Debugger\autoexp.dat
contains a series of type=string declarations that allow you to customize what MS DevStudio is showing in the watch window and tooltip when debugging your application. A bit of doc and examples are here [www.muenster.de], and this is a start for the impatient ones:

TString= <fData> TNamed= name=<fName.fData> title=<fTitle.fData> TCollection= size=<fSize> TClonesArray= size=<fSize> type=<fClass.fName>
Enjoy!
Axel.

Hi Axel, thanks for good hint.
Just another hint from CVS log:

* base/src/TError.cxx:
From Valeriy Onuchin:
- I introduced debugPrint function which
  prints debugging message to stderr and to the system debugger under Windows.

Printing to the system debugger is usfull for debugging pure GUI (without console)
appications under MS Windows.

The functions (Info, Warning etc.) from root.cern.ch/root/htmldoc/TError.h
now printing debug info into debugger window
(“Command” window in WinDbg)

Regards. Valeriy
