Hi
I have a SDI application, within that i have a property sheet, which has several property pages

I need to pass my Document pointer to some of the property pages

I can pass the doc pointer to the sheet via DoModal OK like

ie.

CMyAppDoc* pDoc = GetDocument();
CMySheet dlg;
dlg.DoModal(pDoc);

however once at the sheet i need to pass it to some of the pages

does anyone know the correct way of doing this

i load each of my pages in the constructor in my property sheet
like

AddPage(&m_Page1);

Thanks

Si

put a call in your sheet that can take the pointer and pass it to all the pages:

void CMySheet::SetDocPtr(CDocument *pDoc)
{
m_page1.m_pDocPtr = pDoc;
..etc
}

Yes, just name the files with a .c extension and they'll be treated as C files. There's also a compiler switch to force this behavior for any file (in case they don't have a .c extension and you can't rename them).

Memory Management Problem

How to delete an object by giving time limit to it.

Like, if an object is not referenced by anyone for say 5 minutes then it must get deleted by itself.

Please give me some logic for this.

CString strMessage;
strMessage.Format ("var = %d", m_terma);
AfxMessageBox (strMessage);

You're probably better off using the TRACE() macro.

i think m_terma is of type integer.
so this

CString csMsg;
csMsg.Format("%d", m_terma);
AfxMessageBox(csMsg);

try it out

What about setting the breakpoint after UpdateData, and seeing the value in the Quick Watch Window!

If this is your actual C++ code:

CString sPath = "c:\some folder\some file.txt"

then it's wrong. The \s will be treated as one character. In a string literal, \ is a special character, and you write \\ to get one backslash.

Are you sure that you need this conversion???

The char \ is coded into the symbol \\ only to find a way to tell at the compiler that we want to use that char: So I can't understand why you need this char conversion: they are only 2 way to see the same thing.

And this is the reason because the first line
(

CString sPath = "c:\some folder\some file.txt"<br />

)
is wrong(see \s, as is saying Michael), and you can't use it.

Hope it helps.
