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

the poster may contain any number of elements.

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.
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 ...

Another problem is that I Want to save the poster to modifie it later.
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

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.

Not on mine... just "MFC in shared DLL" and attempting to add I don't have the static library feature.. and even after a full install don't have it. Do YOU?

I have Enterprise Edition. I just looked it up. The Comparison Chart of Features in Each Visual C++ Edition says Static linking to the MFC Library isn't offered in the Standard Edition. That sucks!

hey... i found that out too. I did a msg that I can find a work around here on codeproject but searching for it seems to be rather a pain... I appreciate your assistance though.. if you aren't easily offened, see this link.. I just posted the phote enough people told me its not really offensive... http://profiles.yahoo.com/cpp_w_mfc[^] it won a best costume at a halloween party here locally.

I just took a peek at your profile. Just thought it worth mentioning that I recently considered hiring a programmer to help me out with some of the "grunt" work and mentioned it in the lounge here. I was actually thinking of hiring between two local people I know but the reponse to my query got me to realize the CP is likely a better idea for finding programmers. Doesn't pay a great deal... right now I can only offer $30(US) and hour and it would be spuradic.. mostly needed when I agree to very short dead lines. Just the same... if you think you might be interested, my email is mfeik@comporium.net and I just started my own company and as it grows (as I hope it does, I will be able to pay better.

I think the Standard edition won't let you link statically from the GUI. I know ther eis a way around that thoguh, and I think it is in a CP article. I don't knnow where it is at the moment though... but it involves hacking the DSP/MAK files...

Hey all, I am writing a little utility which will syncronize data with the Outlook Task folder. I am using MFC. I have done some searching on how to do this, but most of the info I have found on the net and on MSDN is using VB, which I can't use for my purposes.
Can any of you point me in the right direction, please?
Thanks!

hi,
does anyone know where i can find out more information on graphic user interface programming in vc++? i'm talking about the programming of the gui with animated buttons and menus that are similar to the ones in games(e.g. nhl2003, nbalive 2003, madden2003..etc), winamp, sonique and wmp(i'm not talking about programming skins).. any suggestion is welcome.. tia!

Here ? There's lot of different GUI stuff on this site. The stuff within games is likely to be done in DX, I would have thought, but there is a skinnable app sample that looks a lot like WinAm ( and plays mp3s ), and heaps of other stuff as well.

Hi,
Im trying to put a CList into a struct or class and include that in another CList, does anyone know how to do this whithout getting errors?
Cheers
|
|

|

I think I know what you mean, this example uses stl::list ( and so should you ), but it compiles fine.
#include <list>
using std::list;
struct myStruct
{
list<int> lInt;
int i;
char * pChar;
};
int main(int argc, char* argv[])
{
list <myStruct> myList;
return 0;
}

This one got me too, caused me no end of hassles. Best thing to do is forget the MFC CList related class and go straight for the STL ones.

The same thing is valid for all MFC containters (CArray). Use std::list.
