I have created a Resource-only Dll viz. Language, which includes only resources i.e
Dialogs,
Toolbars,
Acceleraters,
Bitmaps,
Icons,
String Tables,
Version etc.
I have created one Dialog Based Application viz. LanguageApp, which includes only code - nothing else.
Now, I want to load each-n-every resource from the dll Language to application LanguageApp without including resource.h file of the dll.

Use the APIs FindResource and LoadResource.

Hence you cannot add resources to the DLL!

Are you talking about the GetCheck() and SetCheck() methods?

Add this on the topmost line in .cpp files.
#include "stdafx.h"

Where is the project from? You created it? Or you got from someone else?
If the project is created by yourself, either project type MFC or Win32 generates an "stdafx.h" file automatically in the project folder, unless you were starting from an empty project.

u right click your source code .cpp, and go to setting,in category, u choose precompiled headers and also check not use precompiled headers..that is all..any problem, tell me..

Per MSDN:
A precompiled header was specified, but it did not contain a precompiled header directive.
This error can be caused by specifying an incorrect file as a header file, or by specifying an include file with the /Yu (Use Precompiled Header) command line option that is not listed in the source file as an include file.

Hi,
I am creating an MFC app as well as learning about design patterns and good coding practices, and so I've got a question for you whizzes...
I am creating a class to control a dialog which fills in a DirectX materials structure:
typedef struct _D3DMATERIAL9 {
D3DCOLORVALUE Diffuse;
D3DCOLORVALUE Ambient;
D3DCOLORVALUE Specular;
D3DCOLORVALUE Emissive;
float Power;
} D3DMATERIAL9;
My question is thus:
The class I am creating for this control should take a pointer to a struct (as above) as an argument for it's constructor. This is not a problem if the control is being used as a modal dialog:
D3DMATERIAL9 Mat;
CDX9MaterialDialog dlg(&Mat);
INT_PTR nResponse = dlg.DoModal();
But when the dialog is being used as a child, I have to declare the class as a member of the parent dialog, right? How can I ensure that the my class is initialized with a valid pointer, when the parent dialog class will use the default no argument constructor for the class?
I would like to make sure that the dialog is initialized with a pointer so that the dialog class is not responsible for creating (and deleting) a new material structure.
Thanks - @LG

in the dialog, you will have a member pointer to the D3DMATERIAL9 structure, just be certain you initialize it to NULL in the constructure; and create a Set function to set the structure in the dialog.
in pseudo code.
class YourDialog
{
YourDialog();
D3DMATERIAL9* m_pMaterial;
void SetMaterial( D3DMATERIAL9* pMaterial) { ASSERT( pMaterial); m_pMaterial = pMaterial;};
};
YourDialog::YourDialog() : m_pMaterial(NULL)
{
}
and now, it's your job to check that each time you access m_pMaterial it is not NULL.

it adds more coupling between YourDialog and clients, assume what does it happen if doing this:
D3DMATERIAL9 *pMeterial = new D3DMATERIAL9 ;
YourDialog dlg;
dlg.SetMaterial(pMeterial);
delete pMeterial;
dlg.Dosomething(); //this function relies on m_pMaterial
it undoubtedly uses an invalid pointer, I think the better way is either change the function name to make callers clear YourDialog instance is attached to D3DMATERIAL9 pointer or maitance a D3DMATERIAL9 object inside of YourDialog class. it's much easier to change function name to: YourDilaog::AttachMaterial(D3DMATERIAL9 *pMaterial)
life is like a box of chocolate,you never know what you r going to get.

Thanks for the insights you guys.
Will, I think you're right... in either case the only way for the dialog to be sure that the D3DMATERIAL9 structure is valid is if it maintains one locally and copies it's value to one supplied by a client on request.
Sucks, 'cuz that will slow everything down a bit, but I can't see a way around it.

So I'm making a dialog based app in MFC, and I'd like to make a child Dialog that is acts like a control and part of my parent dialog... Seems like a very easy task, but for some reason I must be doing something wrong... I see a tutorial here on CP explaining it (http://www.codeproject.com/KB/dialog/CRHChildDialog.aspx[^]), but I don't like that solution, I'd rather not have to include someone else's custom code in my project...
Anyone know of any other tutorials?
Sorry if this has been asked before; I searched and didn't find much.

Well, the mentionned article looks like a great tutorial, it probably wraps usual code for doing that sort of task :
but it general it goes like that ( will not show you code since you do not want to use someone else's code )
- create parent dialog resource with a "placeholder" for the child dialog.
- create dialog resource with the "control parent" style (and another flag that I forget the name )
- create the parent dialog as you would do normally.
- in the OnInitDialog, get the RECT of the placeholder, create the child dialog (as a member of the parent dialog). Create it in the appropriate position, using the RECT.
normaly, that will be sufficent (as far as I can recall now )
