Using resource defined in MFC DLL project from ARXProject

Anonymous — Wed, 18 Jun 2008 14:58:42 GMT

Hello,

We use AutoCad Architect 2009 with ObjectARX 2009 and Visual Studio 2005 SP1.

We define in an ARX Project the function below :

void CSendingCommandsApp::AdskSendingCommands_TEST1(void)
{
CAcModuleResourceOverride temp;
CDisplay a;
a.Display();
}

In this function, we want to display a resource define in a MFC extension DLL.

void CDisplay::Display()
{
CString cs;
cs.LoadStringW(IDS_Hello);
AfxMessageBox(cs);
}

When we execute our command TEST1 in Autocad, we have an Assert in AfxWin1.inl :

_AFXWIN_INLINE HINSTANCE AFXAPI AfxGetResourceHandle()
{ ASSERT(afxCurrentResourceHandle != NULL);
return afxCurrentResourceHandle; }

Thank you for your help,

Is CDisplay::Display() defined in the .arx module? Did you use the
ObjectARX wizard to create your project skeleton?

Hello Owen,

Tanks for your reply.
I've found a solution, and it's work fine!! But now, I've another problem when I try to load a DialogBoxe defined in my MFC dll...
To answer, your question, yes I use the ObjectARX wizard to create my project skeleton and The CDisplay::Display() method is defined in my MFC DLL module.

First, that is what I have done (if it could help someone else...) :

In my ARX module :
------------------

void CSendingCommandsApp::AdskSendingCommands_TEST1(void)
{
CAcModuleResourceOverride temp;
CDisplay a;
a.Display(acedGetAcadResourceInstance(), acedGetAcadFrame() );
}

In my MFC DLL module :
--------------------

In the CDisplay.h file :

static HINSTANCE hInstanceSafe;

In the entry point of my MFC DLL module :

DllMain(HINSTANCE hInstance, DWORD dwReason, LPVOID lpReserved)
{
CDisplay::hInstanceSafe = hInstance;
...
...

}

In the CDisplay.cpp file :

HINSTANCE CDisplay::hInstanceSafe = NULL;
void CDisplay::Display( HINSTANCE h, CWnd* pParent )
{
AfxSetResourceHandle( hInstanceSafe );

CString cs;
cs.LoadStringW(IDS_Bonjour);
AfxMessageBox(cs);

AfxSetResourceHandle( h );
}

The Step2, and my real goal, is to display a DialogBoxe, defined in my MFC DLL module.
I've tried all solutions I've found on the net, but nothing work for me.

Now, when I call DoModal(), I have an Assert in objcore.cpp :

BOOL CObject::IsKindOf(const CRuntimeClass* pClass) const
{
ENSURE(this != NULL);
// it better be in valid memory, at least for CObject size
ASSERT(AfxIsValidAddress(this, sizeof(CObject)));
...
...
}

That is what I have done :

In my ARX module :
------------------

void CSendingCommandsApp::AdskSendingCommands_TEST1(void)
{
CAcModuleResourceOverride temp;

CDisplay a;
a.Display( acedGetAcadResourceInstance(), acedGetAcadFrame() );
}

In my MFC DLL :
--------------

void CDisplay::Display( HINSTANCE h, CWnd* pParent )
{
AfxSetResourceHandle( hInstanceSafe );

CDlgBidon* pDlg = new CDlgBidon( pParent );
pDlg->DoModal();
pDlg->DestroyWindow();
delete pDlg;

/*CString cs;
cs.LoadStringW(IDS_Bonjour);
AfxMessageBox(cs);*/

AfxSetResourceHandle( h );
}

What's going wrong??

Thanks for your help,

Sophie D.

Elcom,

Have you added this macro prior to running you function?

myFunction()
{
MFC_RESOURCE_INIT;

do_it_now();

}

Hello Gary,

Thanks for your reply, but could you be more clear please? I don't understand what you suggest me to do. What is this macro MFC_RESOURCE_INIT? I don't find it.

Sophie,

Sorry about that was one of ours!

I think your problem is here.

DllMain(HINSTANCE hInstance, DWORD dwReason, LPVOID lpReserved)
{
CDisplay::hInstanceSafe = hInstance;
...
...

}

You don't appear to be initializing it!

Try this!
DllMain(HINSTANCE hInstance, DWORD dwReason, LPVOID lpReserved)
{
if (dwReason == DLL_PROCESS_ATTACH) {

_hdllInstance = hInstance;

// CDisplay initialization

CDisplay::SetDefaultResource(_hdllInstance);

}

..................

}
