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 
khaldoun wrote:

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

I suggest you use a container (CArray or maybe std::vector) of pointers to CElement objects.
Use virutal methods to implement the CElement-derived classes so when you iterate through the container of pointers, thanks to polymorphism, you don't have to worry about calling the right method.

VC add resource(Version, Icon, Menu, Dialog etc.) to MFC app/dll automaticly.
but not Win32 DLL.
we need add standard version info(like what you see in the Properties dialog of a DLL file in Windows Explorer) to a DLL project. any advice is welcome

From the IDE, it is not difficult.
With your projet open, go to File | New, and choose "resource script". Make sure you insert it in your project, and you can then edit its resources like you would anything else.
Just don't try to use Class Wizard.

I need in my program to get the default web browser on my system. How???
|
|
|
|

Why do you need to get the default browser? If you are just launching an HTML file, check out the ShellExecute function, which launches whatever program is associated with the file type specified.

I need open many instances of a browser in separate windows and uses for it CreateProcess, so SheelExecute in this case is not applicable.

Where is the [edit]"use MFC in a static library"[edit] option in VC6SE (standard edition). I ran across this question in a another forum and realized I'm going to need the answer myself as I'm using an older machine with the SE version on it (Crashed my other PC and wont have it running again until sometime tomorrow - which wont help me in about two hours when I compile the release on the project I'm working on now) and no license to upgrade on this PC. Anyone know, its been a long time since I've used this PC for programming apps.
