Is this an IDE bug or is something screwed up within the project.
It's definitely not normal behavior. Does it happen with all of your projects, or just one in particular? Have you tried deleting the project's temporary files (e.g., .ncb, .opt, .aps, .clw)?

Its just this project. I did try what you suggested and also I replaced the numbers with the ID/IDC's. I even tried to replace the ID/IDC's in both the properties box and in the <progam>.rc file also for a few items, as the numbers are in this file also.
But still they revert back to numbers.
Are they anything that can be done to corrct this problem, or should I raise a call with Microsoft (I am allowed two with my support level).

On Win9x, i think the HKEY_DYN_DATA registry key provides some performance data, but im not sure if the CPU's included..
On NT/XP/2000, use performance counters:
HQUERY hQuery;
HCOUNTER hCounter;
if(ERROR_SUCCESS == PdhOpenQuery(0, 0, &hQuery))
{
if(ERROR_SUCCESS == PdhAddCounter (hQuery,TEXT("\\Processor(0)\\% Processor Time"),0,&hCounter))
{
int i = 0;
while(i < 5)
{
++i;
if(ERROR_SUCCESS == PdhCollectQueryData(hQuery))
{
PDH_FMT_COUNTERVALUE val;
if(ERROR_SUCCESS == PdhGetFormattedCounterValue(hCounter,PDH_FMT_LONG|PDH_FMT_NOSCALE,0, &val))
{
printf("\nCPU is at %d %%",val.longValue);
}
}
Sleep(500);
}
PdhRemoveCounter(hCounter);
}
PdhCloseQuery(hQuery);
}

}

}

}

Hi all,
an application gives stack overflow..as a workaround, increasing the
from 1MB to 16 MB stack size in the project setting solves the problem..
Is there any upper limit upto which the stack size can be increased..or any issue
will occur due to stack size raise..??
Is there any 3rd party freeware / share ware / paid tool which would display the
function stack in a multithreaded environment..Better than call stack in vc++ IDE..?
Any lights on this would be highly appreciated...
Thanks,
Shiva P

I have this code snippet used to keep the window on the top.
<br />
SetWindowPos( &wndTopMost, 0,0,0,0, SWP_NOSIZE | SWP_NOMOVE | SWP_SHOWWINDOW );<br />
The problem is that is starts minimized...how can I ensure this window starts visible?

So which is it, a window that starts non-minimized, one that is visible, or both?

Sorry...I guess I did make that a bit unclear.
I didn't mean the window wasn't visible, just minimized. I want it to start non-minimized.

Is it an SDI/MDI app, or a dialog-based app?

Dialog.

Are you making any calls to ShowWindow(), or does the dialog template have the WS_MINIMIZE style?

Hi ,
I would like to send a message function from 1 Dialogue to another dialogue,Just to notify him that he has to do something.Is there any function like that existing inside the CDialog class.
Inside this function,would like to write "code"(UserDefined code),which the function should perform......
Thanks....

One question...
The another dialogue is inicializaed simultaneosly and in another class?

Can you use SendMessage() or PostMessage()?

The Problem for me is I have created different tabs deriving from a CDialog object. I have 2 command buttons "OK" & "Cancel" & they reside in a dialog window(Not part of tabs dialog)
class C_TabControl : public CTabCtrl
{
// Construction
public:
CDialog *m_tabPages[13]; // Here Iam creating my tabs
So when the user presses "OK" by changing something in the tabs,I want to send a "function call" from the " C_TabControl" object to the tab.
As the Tabs are derived from CDialog,I can't define a function in the tab & call it using m_tabPages[0].
the compiler will complain that the "userdefinedfunction" not defined in CDialog.
So was looking for a function in CDialog which I can override to accomplish this purpose.

What's wrong with:
class CMyDialog : public CDialog
{
public:
userdefinedfunction();
};
class C_tabControl : public CTabCtrl
{
public:
CMyDialog *m_tabPages[13];
};
m_tabPages[13]->userdefinedfunction();

Hi
i make 1 instance of CMyClass in the ThreadProc function and call Init member function :
int CMyClass::Init(int ID)<br />
{<br />
m_ChID=ID;<br />
int res=pInitChannel(m_ChID);<br />
<br />
if(0==res)<br />
return true;<br />
else<br />
{<br />
ReportError(res);<br />
return false;<br />
}<br />
}
I know (and correct me if wrong) that the ID parameter and m_ChID are safe.
I mean that if i pass 0 from a thread and 1 from another then there is no chance that m_ChID member will have the same value 0 or 1 for both instances since m_ChID is not a shared variable..
the problem that arises that the library i call (which have the global pInitChannel function) should be thread safe but i get an error that indicates that I pass the same ID more than once (which is not allowed).
now the question is :
Am I wrong with my concepts or does the library i use have problems with multithreading ?
thank you for reading

hello,
I use MFC and new I need to create controls (buttons) on-the-fly and add message
handlers to them for the BN_CLICKED event at the time they are created. I see how
the messagemap functionality can add handlers for the controls that I already
have on my form, but what about dynamically created.
I do not wish to create an excessive amount of controls and just hide the
ones that are inappropriate at the time..
(cause: where di I set the limit as to what is a safe amount of controls then..)
thankful for any help I can get.

Hi,
You can intercept the button down message (WM_LBUTTONDOWN) or any button in the PreTranslateMessage(MSG* pMsg):
BOOL CYourDialog::PreTranslateMessage(MSG* pMsg)
{
if(pMsg->message == WM_LBUTTONDOWN)
{
CWnd *wnd = CWnd::FromHandle(pMsg->hwnd);
int ID = wnd->GetDlgCtrlID();
if(ID == IDC_OWNBUTTON1)
{
MessageBox("IDC_OWNBUTTON1");
return TRUE;
}
if(ID == IDC_OWNBUTTON_N)
{
MessageBox("IDC_OWNBUTTON_N");
return TRUE;
}
}
return CDialog::PreTranslateMessage(pMsg);
}
The IDC_OWNBUTTON1 ... IDC_OWNBUTTON_N is an custom control id's
