Environment: Win98, VC 5.0
Do you have code like this in your InitInstance() ?
Then this is what you need!
The cdxCInitializerT base class helps you to design
a proper, clear interface to initialize any objects you want in application scope (i.e. your
CWinApp object exists during the initialization).
The basic idea is to design a class (cdxCInitializerT)
that has two static members, InitInstance() and
ExitInstance() which must be called from within your
These functions should now initialize all exisiting objects of
cdxCInitializerT by calling a virtual function
OnExitInstance() is called to clean up what you
allocated using OnInitInstance(). This is exactly
what the cdxCInitializerT class offers you –
an interface to initialize/clean up your objects that have been constructed in global scope
(static members variables, global variables).
Moreover, the class can be parameterized (by two template arguments) to give you the chance
to provide feedback to the calling function (i.e. each of your objects can get a pointer to
a "splash screen" dialog where it can write nice stuff into). Additionally,
the design gives you the opportunity to define an ordering of the initialization (object A
will be initialized after B for sure).
Finally, a former class, cdxCInitializerThreadT has been
added that helps you to implement a splash screen in a second thread easily (you just need a
dialog and some member functions to modify its controls – that’s it!).
If you use my class, you should make your InitInstance()
look like this:
and all your nasty classes that used a "GlobalInit()" before will be set up properly –
and adding new "GlobalInit()" classes will be easy; you don’t need to modify your
application’s implementation file anymore.
