From: MuMbi on 2 Feb 2010 21:47 Hi. I created MDI project. the project provided CChildFrame as default. I need other doc template and child frame. So I added doc template on App::InitInstance() like this. m_pColladaDocTemplate = new CMultiDocTemplate( IDR_ColladaTYPE, RUNTIME_CLASS( CColladaDoc ), RUNTIME_CLASS( CColladaFrame ), RUNTIME_CLASS( CColladaView ) ); CColladaDoc, CColladaFrame, CColladaView are new classes defined by me. This is a problem. RUNTIME_CALSS( CColladaFrame ) returns CRuntimeClass. the CRuntimeClass has m_pfnCreateObject that is default constructor pointer. But, the m_pfnCreateObject was NULL. I tried changing frame class to CChildFrame. In this case, the m_pfnCreateObject was not NULL rightly. What problem does My CColladaFrame have? I think I'am missing something out. Waiting your helps.
From: Joseph M. Newcomer on 2 Feb 2010 23:12 You missed three critical pieces of information here: what is the runtime type of the document, frame, and view. It should be DECLARE_DYNCREATE or DECLARE_SERIAL, with a corresponding IMPLEMENT_DYNCREATE or IMPLEMENT_SERIAL. So you need to examine the header files for each of these classes and make sure they correspond to the requirements for a dynamic template. joe On Tue, 2 Feb 2010 18:47:02 -0800, MuMbi <MuMbi(a)discussions.microsoft.com> wrote: >Hi. > >I created MDI project. > >the project provided CChildFrame as default. > >I need other doc template and child frame. > >So I added doc template on App::InitInstance() like this. > >m_pColladaDocTemplate = new CMultiDocTemplate( IDR_ColladaTYPE, > RUNTIME_CLASS( CColladaDoc ), > RUNTIME_CLASS( CColladaFrame ), > RUNTIME_CLASS( CColladaView ) ); > >CColladaDoc, CColladaFrame, CColladaView are new classes defined by me. > >This is a problem. > >RUNTIME_CALSS( CColladaFrame ) returns CRuntimeClass. > >the CRuntimeClass has m_pfnCreateObject that is default constructor pointer. > >But, the m_pfnCreateObject was NULL. > >I tried changing frame class to CChildFrame. > >In this case, the m_pfnCreateObject was not NULL rightly. > > >What problem does My CColladaFrame have? > >I think I'am missing something out. > >Waiting your helps. > Joseph M.

From: MuMbi on 3 Feb 2010 00:34 Theses classes was created automatically by Wizard provided from VisualStudio. So, They already have MACROs you mentioned. I tried copying & pasting CChildFrame contents in .h, .cpp files to My CColladaFrame files and changing the class name to CColladaFrame. Then, it works well! I can't find difference between old CColladaFrame and new. It looks same. I feel frustrated sadly. T_T "Joseph M.

I wasn't sure if you were using VS to create them; there are a set of people out there who refuse to use the tools, and this is the most common mistake they make. More below...

Clearly something is, so all you need to do is compare the two files and see! joe **** > >Then, it works well! > >I can't find difference between old CColladaFrame and new. > >It looks same. > >I feel frustrated sadly.
