Trouble making a font name list

Hi, i'm trying to fill a CComboBox with the system's font names. This is the callback funtion:

Code:

int CALLBACK CWordProcessorDlg::EnumFontFamProc(LPENUMLOGFONT lpelf, LPNEWTEXTMETRIC lpntm, DWORD nFontType, long lParam)
{
	m_ccbfontlist.AddString(lpelf->elfLogFont.lfFaceName);
	return 1;
}

This is how i call the CALLBACK:

Code:

LOGFONT lf;
CClientDC dc(this);
::EnumFontFamiliesEx((HDC)dc,&lf,(FONTENUMPROC)EnumFontFamProc, (LPARAM)this,0);

But i get error msg C2440 on EnumFontFamiliesEx():

Code:

error C2440: 'type cast' : cannot convert from '' to 'int (__stdcall *)(const struct tagLOGFONTA *,const struct tagTEXTMETRICA *,unsigned long,long)'

Please help.

Your EnumFontFamExProc is of the wrong type - you can't use a non-static c++ class member function when what EnumFontFamiliesEx requires is a pointer to a stdcall function returning an int and taking four parameters (your c++ member function comes encumbered with this). Making the c++ class member function in question static is the usual way to resolve this issue.

i think that solved it. Thanks.

sorry, but there's another problem. When i make EnumFontFamExProc static, the:

Code:

m_ccbfontlist.AddString(lpelf->elfLogFont.lfFaceName);

call gives error no C2228 : left of '.AddString' must have class/struct/union type". But 'm_ccbfontlist' is of type CComboBox. Why is this?

Where is it declared? Is it in the right scope?

yes, m_ccbfontlist is declared in the correct header file and is in the right scope.
Above error only happens when i make EnumFontFamExProc a static one. ??

The static member function can only access globals or other static member functions or data from the same class.

Pass a pointer to your c++ class as the LPARAM of the EnumFontFamiliesEx (it's the same application defined value that is passed to your EnumFontFamExProc function) and then use that to access member functions.
