If this code is outside a CWnd object (which is probably the case), you should try this:
CAlarmEndDlg dlgEnd;
dlgEnd.SetTime(szTime);
dlgEnd.SetWindowPos(&CWnd::wndTopMost,60,80,0,0,SWP_NOSIZE);
dlgEnd.DoModal();

Use dlgEnd.SetWindowPos(&CWnd::wndTopMost,60,80,0,0,SWP_NOSIZE); instead.

Thanks for both replies !! Yes, the use was within a global function (Timer callback) and the use of CWnd:: has cured the problem. Just given myself a smacked hand for not trying that before posting the cry for help !! Thanks again !

Hi,
Hope I am not asking a stupid question
But since notification of say receive or send is done via messages
Is there a Windows Based message to go with Virtual Function say
OnReceive e.g. WM_SOCKET_RECEIVE
and its user based message that the Server sends What if the Server is
a non Windows/DOS BASED computer
|
|
|
|
|
Notification of send or receive is done by the CAsyncSocket class using the OnReceive virtual function. If you don't use this class you will not get any notification. It would simply be the send/recv or WSASend/WSARecv function calls. CAsyncSocket class probably uses these functions internally.

In otherwords the DLL used by AfxSockinit
on a Send From (the Server on the Some other machine/Computer)
would know to call CASycSocket::OnReceive ???
(I have been able to send messages using the WinSock/SDK "C" api's )
So in other words there aren't any message map entries necessary for
OnReceive
thankx again

consider the below code
class ab
{
public:
virtual void foo(int a = 2) = 0;
};
class ba : public ab
{
public:
void foo(int a = 4){std::cout<<a;}
};
int main()
{
ba tst;
ab &tst1 = tst;
tst1.foo();
}
this will print me 2 i.e base class signature is used so is default arguemts are resolved during complie time or runtime and why is the above doing so { but i was excepting it to be 4 (derived default)}

Default arguments are resolved at compile time. (This is by necessity to build the stack correctly prior to the call. Thus, once a virtual function is called through the vtable, the call stack must already be set up.)

joe,
but y is it sets the argument to base function signature arguments..
|
|
|
|

Because that's all it "knows" about. The use of the virtual function isn't done (or technically "known") until runtime.

The C++ standard says this about default arguments (in section 8.3.6 para 10):
10 A virtual function call (10.3) uses the default arguments in the declaration of the virtual function determined by the static type of the pointer or reference denoting the object. An overriding function in a derived class does not acquire default arguments from the function it overrides.
Note the use of static type of the pointer or reference - the static type of your reference is a reference to the base type, so it uses the base type's default parameter value.

hi if using sizeof function will this be resolved during
1. runtime
2. compile time
3. pre-compile time
please give me answers
|
|
|
|
|
sizeof() is not a function, but a compile time operator. (Amazingly enough Google gives that answer as the second hit.)

Have you tried to figure this out for yourself ? Most compilers can write their preprocessor output and this would tell you.
|

York,
can u hint how to do it..
plz..
|

One way to see this is to have the compiler generate machine and assembly source (in output, depending on the compiler.) If you don't understand assembly, though, it may not do much good.

If you are using Microsoft compiler,
Take a look its (CL.EXE) options - cl.exe /?
-PREPROCESSOR-
/AI<dir> add to assembly search path /FU<file> forced using assembly/module
/C don't strip comments /D<name>{=|#}<text> define macro
/E preprocess to stdout /EP preprocess to stdout, no #line
/P preprocess to file /Fx merge injected code to file
/FI<file> name forced include file /U<name> remove predefined macro
/u remove all predefined macros /I<dir> add to include search path
/X ignore "standard places"

A simple linked list. Do something with the first, then move the first to the end (don't forget to update the pointers). Repeat to achieve round robin. Three words aren't going to get you any code - be specific and understand that this is not RentACoder; chances are you'll get helpful hints, not complete solutions

How to let an SDI-Appliction automatically scroll to present the last line of very long text in the output?the class used hier is CEditView.
|
|
|
|
|
Use CEditView::GetEditCtrl to get a reference to the edit control in the form of a CEdit class instance. Then you will need CEdit::GetLineCount, CEdit::LineScroll and CEdit::SetSel to perform the actual scrolling.

Hallo and thanks for the reply , i have this code in the Tes_Doc.cpp
CEdit &EditOutput = m_ptrOutput->GetEditCtrl ();// m_ptrOutput is CEditView Pointer
nLineCount = EditOutput.GetLineCount ();
EditOutput.LineScroll (nLineCount);
DWORD dwSel = EditOutput.GetSel();
EditOutput.SetSel (dwSel,true);
EditOutput.SetWindowTextA(m_strOutput);
The code does not work. I do not know why?
|
|
|
|
|
Try this sequence.
CEdit &EditOutput = m_ptrOutput->GetEditCtrl();
EditOutput.SetWindowTextA(m_strOutput);
LineCount = EditOutput.GetLineCount();
EditOutput.LineScroll (nLineCount);
