Is IDC_Realm a valid window handle (not a resource id)? Have you tried:
GetDlgItem(IDC_Realm)->SetWindowText("Hello");

Make IDC_STATIC_NEW_CALL as a control variable of type CStatic and then try SetWindowText on it .

Hi,
Is there any way to get the size of an allocated memory buffer knowing only the its address?
Thank you all
|
|
|
|
|
|
No
it doesn't worked for me !!!
The _msize function returns the size, in bytes, of the memory block allocated by a call to calloc, malloc, or realloc.
Thank you anyway

In case of objects allocated with new operator, the number of items seems to be stored in a word before the pointer:
MyClass * a = new MyClass[10];
__int32 size = *(((__int32*)a) - 1);
This works only when the class contains destructor.
The size does not seem to be stored in such manner for destructor-less objects and for fundamental types. But for this cases, _msize appears to return the size in bytes.

The short answer, is no. The long answer is that if you know something about the memory, you may be able to. For example, if it is a BSTR you can look 4 bytes before its "handled" address or use SysStringLen(...) .
If you know that the memory came from a particular heap (or heap manager), you may be able to crack the heap structures used to maintain memory allocations. You also need to know where the memory came from in order to use functions like _msize(...) , _msize_dbg(...) , GlobalSize(...) , etc.

Here it is:
LPVOID data = MapViewOfFile(m_hMap, _dwDesiredAccess, 0, _dwOffset, _dwNbBytes);
I need to know the size of the data buffer.
I call this code after resizing a map file with 8ko but I can acess only the first 4ko
could someone help me?!!

Isn't that what _dwNbBytes represents?

no, _dwNbBytes == 0
ko mean kb == 1024 bytes
thx

Then you simply need to look at the size of the file, since the entire file was mapped.

that s the problem!!! it seems that the size of the file is larger than the memory buffer returned. I don't understand why

wrote smth like this...
variables:
CTabCtrl m_tabctrl;
CDlg1* dlg1;
CDlg2*dlg2
MyDialog constructors ... :
CDlg1::CDlg1(CWnd* pParent /*=NULL*/)
//: CDialog(CDlg1::IDD, pParent)
{
this->Create(CDlg1::IDD, pParent);
this->ShowWindow(SW_NORMAL);
}
BOOL CMainDlg::OnInitDialog()
{
CDialog::OnInitDialog();
m_tabctrl.InsertItem(0,_T("1111"));
m_tabctrl.InsertItem(1,_T("2222"));
dlg1=new CDlg1(GetDlgItem(IDC_TAB1));
dlg1->ShowWindow(SW_SHOW);// error IsWindow=false
}

Hope I understood your question
<br />
dlg1=new CDlg1();<br />
dlg1->create(...)<br />
dlg->GetDlgItem(IDC_TAB1)->ShowWindow(SW_SHOW); <br />

did as u say....
CMyDialog *MyDialog;//in MainDlg header file
MyDialog = new CMyDialog; //in mainDlg constructor
CMainDlg::OnInitDialog{
TC_ITEM TabItem;
TabItem.mask = TCIF_TEXT;
TabItem.pszText = _T("111111");
m_tabctrl.InsertItem( 0, &TabItem );
TabItem.mask = TCIF_PARAM;
TabItem.lParam = (LPARAM)MyDialog;
m_tabctrl.SetItem(0, &TabItem);
VERIFY(MyDialog->Create(CMyDialog::IDD, &m_tabctrl));
MyDialog->ShowWindow(SW_SHOW);
}
CMyDialog constructor
CMyDialog::CMyDialog(CWnd* pParent /*=NULL*/)
: CDialog(CMyDialog::IDD, pParent)
{
/*this->Create(CThumbViewDlg::IDD, pParent);
this->ShowWindow(SW_NORMAL);*/
}
error in HWND CDataExchange::PrepareCtrl
if (pSite == NULL)
{
TRACE(traceAppMsg, 0, "Error: no data exchange control with ID 0x%04X.\n", nIDC);
ASSERT(FALSE);
AfxThrowNotSupportedException();//<-------------------------------------|
}

one question "VERIFY(MyDialog->Create(CMyDialog::IDD, &m_tabctrl));"
your previous code was good this->Create(CThumbViewDlg::IDD, pParent);
this->ShowWindow(SW_NORMAL);
and why you dont use MyDialog->Create();

you just allocated the memory.
You may have to create the dialog using CreateDialog or CreateDialogIndirect

I'm not sure whether your purpose for this will allow for it, but you might try using a PropertySheet/PropertyPage setup instead of a tab control. You can configure the PropertySheet to look just like a tab control and don't have to write the transition code yourself.

OK... In a pseudo-bet, I am wondering if the MFC developers out there can see what is wrong with the following catch clause extracted from an example. I am hoping that something obvious pops out of it.
catch( CMemoryException *pExMem )
{
CString csError;
TCHAR caErr[128+1];
pExMem->GetErrorMessage(caErr,128);
csError.Format(_T("An exception has been encountered:\n%s"),caErr);
AfxMessageBox(csError,MB_EXCLAMATION);
pExMem->Delete();
} Hint - it is not about NUL termination.

Either you are trying to delete a stack object or the exception you are throwing might have declared locally.
e.g
try
{
CMemoryException e;
throw &e;
}
or
CMemoryException e;
try
{
throw &e;
}

Well, generally you do not create CException -based objects directly, you are supposed to use the AfxThrow*Exception(...) functions, and CException -based objects are only supposed to be caught by pointer (never by copy or reference), and you are always supposed to call the Delete() function on them unless you are going to re-throw them.
So, no, that is not the problem.
