Hello, Dimitris
I've looked up your code more carefully.
I am afraid you may not solve the problem the way you want.
I think what you should separate the source like someone has advised on roottalk,
Try don't mix ROOT and Windows include files within one source code.
For example just put your int ReadAscii() function into the separate source file
and you will have no need for "TFile include" for your "eva.cpp". The same things for
other functions. This way code will be cleaner and more easy to maintain too.
And of course your task would be much simpler to achieve if you choose the recommended
way, Namely create the DLL with your function and load it in to the regular
ROOT session. I see no advantage of your "stand-alone" code but headaches only.
The main problem you will meet on your way is lacking of the "Console Window". Many
ROOT classes assume the "Console window" for granted to display the various warning
and error messages. Since you created so-called "Win32 application" no "console will be
provided and you will see no message from ROOT. Very likely your application will crash
shortly.
ROOT was designed with the cross platform compatible codes in mind. This is to say
one should not mix the platform depended (like the low level windows management) and
application ROOT-based functions within one and the same piece of code.
I think it is naturally to separate such kind of things. Try to do that and you will
have no problem to fight with.
I think you should create very simple ROOT DLL with the class with ReadAscii
method ONLY. May be you should post your example to roottalk and make it available
on net.
I believe you will get a lot of useful comments on your design and this save your time.
Very likely you will need to spend some time learning ROOT but it will pay off.
I am sorry I can not help much at the moment due my vacation.
With my best regards , Valery
