Question

I have an MFC application using satellites DLLs in order to support the multilingualism. I am using Visual Studio 2010.

I am able to change the language of the core part of the application without any problems. Things go wrong when I try to load a modeless dialog containing a “special” MFC control (CMFCColorButton, CVSListBox, etc).

The problem occurs at the following statement :

m_dlg->Create(SOME_IID, this); // returns false

How should I proceed to load a “special” MFC control from a satellite DLL?

Answer 1

You must register their classes before you reach OnCreate(). For custom controls, this is typically done in the constructor:

CMyClass::CMyClass()
{
    // Pseudo code
    m_mfcColorButton.RegisterWindowClass(AfxGetResourceHandle());
}

For MFC controls, I bet there is an initialization function that needs to be called.
