You should go deeper with the debugger.

I already went deeper in the Debugger, i still could not fix the problem.

Go deeper. Can't you see what assertion is failing?

in the Test_Doc.cpp file(SDI_Appliction), i use the following code:
void CTest_Doc::OnInputFont()
{
CTestFontDialog sfdlg; // CTestFontDialog is derived from CFontDialog
tfdlg.OnInputFontDialog();
}
and this code is in the OnInputFontDialog()
{
LOGFONT lf;
CFont *pFont = GetFont(); // Fehler
pFont->GetLogFont(&lf);
.........
}
the OnInputFontDialog() is in TestFontDialog.cpp this class is derived from CFontDialog.
How can i see what fail the assertion?
m_hWnd = 0x00000000
maybe this is why?

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)?
