Hello,
My app is failing without a reason (aparently), in any time.
I want to write in a file some variables at each 5 minutes to discover this reason.
I have tried to write the percent of RAM used, but this is not the problem. Which others variables or information could I write ??
Thanks,
Cris.

Well, have you tried using a debugger ?
Does it always crash doing the same operations ?
Dave you checked all variables so that they are really initialized ?
Do you check for NULL pointers ? check for valid return values ? check for valid input values ?
Do you have compilation warnings ? use level 3 or level 4 warning level ... and clean as much as possible, and document those you can't fix.

I can't use debugger because I don't know when ocurr the problem.
It doesn't crash doing the same operation.
I'll check the variables ... but it's dificult !!
I did also compile with leve 4 warning. Some I have cleaned (half).
Any other idea ??
Thansk for your help ...
Cris.

You may write a log in text file while programm is running.
code like this will help you to find function, where you have problems. when you find function, you may write more fprintf operators, or debug it.
CMyClass::Func1()
{
fprintf(logfile,_T("Entering Func1"));
...
fprintf(logfile,_T("Exiting Func1"));
}
write to log some useful information, variables, etc...

How can I set to a window never get the input focus ??
Thanks,
Cris.

check for the CWnd::OnSetFocus and/or WM_SETFOCUS. ( or even WM_ACTIVATE )
one way is to set the focus back to the one that loose the focus instead of the one receiving the focus.
void MyWnd::OnSetFocus( CWnd* pOldWnd )
{
(void)pOldWnd->SetFocus( );
}

Ok, this solve the problem. But this cause a flash (kill and set quickly the focus) in the app.
I need to know how avoid that the app set the focus.

What is wrong with appending line breaks to your strings?

You must be joking. This is the best way to get people to ignore your post, it's plain rude.
You need to build a string from your three char arrays, and put a \r\n between each one.

Does anyone know how to programmatically set the maximum size of an event log? (This is possible in the EventViewer, but I don't know how that would work by using the EventLog API.)

You can set it in the registry.. The keys are under..
HKLM\System\CurrentControlSet\Services\EventLog\Application or Security or System...

Hi
This is an object oriented programming question.
I want to make a poster, which contains Images and textes.
the poster may contain any number of elements.
so if I have CElement a parent class, from which I derive CImage, CText, CRectangle, and so on
how can I implement the CPoster class
the main problem for me is that the number of element is not fixe, so I don't know if there is one or 2 or .... images.
Another problem is that I Want to save the poster to modifie it later.
how can I do this?
thank you for help

So the Poster aggregates/contains Images and Texts, so make these two member variables ...

You could past the number of elements as a argument to the CPoster constructor ... and btw make it explicit , since you don't want implict conversion from int (if this is the variale type chosen to past the number of elements) to CPoster ...

That's a very open question , if you are using MFC, take a look at the Serialization support that MFC offers by the dreaded and omnipotent CObject ... it basically serializes by default on a CArchive , must you should override this to add your member variables that are important to maintain the state of your poster , in this case Images, texcts and rectangles ...
This MFC articles explains well the Serialization(Saving/loading) process ...

If I declare a dynamic array of CElement as a member of the CPoster class.
and if i use MFC Serialization,
suppose thant CElement has Save() and Load() methods
and each derived class (CImage, CText, ..) has its implementation of these methods
so when I want to save my poster
for (j = 0; j< m_nNoElement; j++)
rgElement[j].save(strFileName);
and like this when the element is an CImage class I am calling the CImage::Save(strFileName) function
but when I want to load my poster
for (j = 0; j< m_nNoElement; j++)
rgElement[j].Load(strFileName);
here I think that i call the CElement::Load(strFileName) instead of CImage::Load(strFileName)
what do you think
thank you

Yeap, duh, of course you could use a CArray or a CArrayList or a STL vector .. if the number is unknow at compile time , what it's more normal to happen , I should have added this on the previous post

Yes, it's quite natural do this, this is why you derived the CImage and al from CElement, and will make this Load and Save methods virtual in CElement to obtain polimorfic behaviour, didn't you 
BTW your Load and Save methods in the implementation could call the CArchive << and >> virtual methods of COBject as I explained in the post and on the msdn link
