Usually GetFont has retuns valid but you dont have any window(m_hWnd=0x0000) so it cant return anything.

okay how can i have the window? when the ctor of the CFontDilaog is called parameter m_hWnd will be passed as zero, how can solve this?

Its simple you can create it did you see Create?

|
|
CTestFontDialog tfdlg;
tfdlg = this->CreateObject();// did not work
tfdlg.Creat(templatename, hWnd); // did not work
|
|
|
|

For example you can use like this:
CFontDialog *p=new CFontDialog();
p->Create(...);

CTestFontDialog *p = (CTestFontDialog*)new CFontDialog(0,256,0,(CWnd*)this); // this is CTest_Doc
could you please explain this parameters in the create function?
p->Create(LPCTSTR lpszTemplateName, CWnd * pParentWnd = 0);

i need to pass the window through this ctor, the create function did not work because i do not have
a dialog in my rc, all what i need to do is to modify the normal font dialog(disable some fields in it).
CTestFontDialog(LPLOGFONT lplfInitial, DWORD dwFlags, CDC* pdcPrinter, CWnd* pParentWnd) :
CFontDialog(lplfInitial, dwFlags, pdcPrinter, pParentWnd)//pParentWnd ???(is this the window of the sdi appliction???)

The variable sfdlg is not being used. Is this intentional?

sorry it is type error the variable is an object of CTestFontDialog.
All what i need is to use a modified CFontDialog which has font, font style, and size fields this modified font dialog should be called from an sdi application (Class edit view).

Why are you not doing something like:
CFontDialog dlg;
if (dlg.DoModal() == IDOK)
{
LOGFONT lf;
dlg.GetCurrentFont(&lf);
CString strFontName = dlg.GetFaceName();
CString strStyleName = dlg.GetStyleName();
int nSize = dlg.GetSize();
...
}

that is okay but the dialog should have less elements that the original CFontDialog, it should have
Font, font style and font size drop down menu. How can i blind out the other drop down menus?

What line of what file is asserting (hint: what you've shown is not it)?

Have you looked at that line? What version of VS are you using?

hi all
I am writing a application in which i use the stl list. through this list i m able to inserting the items but not able to remove the item from specific position. this is my class
class ClipEntry
{
public:
//CoInitialize(NULL);
ClipEntry();
ClipEntry(const ClipEntry& r);
~ClipEntry();
const ClipEntry& operator=(const ClipEntry& r);
bool operator == (const ClipEntry& r);
private:
IGraphBuilder *m_pGraph;
IUnknown *m_pSinkFilter;
string m_strName;
REFERENCE_TIME m_tOffset;
REFERENCE_TIME m_tStart;
REFERENCE_TIME m_tStop;
// rewound ready to re-use
bool m_bPrimed;
};
I am inserting the items like this
HRESULT ClipPlayer::AddClip(char* path, ClipEntry** ppClip)
{
list<ClipEntry>::iterator it;
it = m_Clips.insert(m_Clips.end(), ClipEntry());
ClipEntry *pClip = &(*it);
*ppClip = pClip;
.........
}
but when i write the remove function like this
void ClipPlayer::RemoveClip(ClipEntry *pClip)
{
m_Clips.erase(&pClip);
// find(m_Clips.begin(),m_Clips.end(),pClip);
}
i am getting error
Could not find a match for 'list<ClipEntry,allocator<ClipEntry> >::erase(ClipEntry * *)'
how i solve this problem

It seems like you're mixing up what type you're storing in the list...
You don't include the declaration for the m_Clips member variable.
Does it store ClipEntry or ClipEntry*?
The compiler error a probably caused by the fact that std::list::erase()
expects an iterator as argument and not a pointer to an element in the list.

so how i pass this argumet in the erase()?
i am getting the whole value of the list in the ClipEntry *pClip which i want to remove.
RemoveClip(ClipEntry *pClip)

As Stuart said, std::list::remove is the function you should use as it expects a reference to an instance of the type controlled by the container.
In code it should look something like this:
std::list<ClipEntry*> m_Clips;
....
void ClipPlayer::RemoveClip( ClipEntry* pClip )
{
m_Clips.remove( pClip );
}
Is your m_Clips really declared as above? I.e., does it store pointers to ClipEntrys?
If it does, you shouldn't need to write a comparison operator for ClipEntry since std::list::remove() would simply compare the pointers in order to find a match. (Referring to you ongoing discussion with Stuart.)

thanks Roger Stoltz for reply
now problem is solved

You want std::list::remove, not std::list::erase.
m_Clips.remove(*pClip);

when i use m_Clips.remove(*pClip);
then i got error
'operator==' not implemented in type 'ClipEntry' for arguments of the same type
while i already implement the operator== like this
bool ClipEntry::operator ==(const ClipEntry &r)
{
if(m_tOffset != r.m_tOffset) return 0;
if(m_pGraph != r.m_pGraph) return 0;
if(m_pSinkFilter != r.m_pSinkFilter) return 0;
if(m_strName != r.m_strName) return 0;
if(m_tStart !=r.m_tStart) return 0;
if(m_tStop != r.m_tStop) return 0;
if(m_bPrimed != r.m_bPrimed) return 0;
return 1;
}
then what should i do for this
|
|
|
|
|
bool ClipEntry::operator ==(const ClipEntry &r)
should be
bool ClipEntry::operator ==(const ClipEntry &r) const
