You realize that the assertion is telling you that you are issuing Scroll Bar Functions to an object that is not realized as a window. That is, the fact that m_HWND is NULL means that you are trying to scroll a window that doesn't exist. I'm not sure of your definition of "working fine" but this ain't my definiton. You should fix these.

You should never, never ignore such assertions. If such assertions fail, it mean that your code is wrong and shouild be fixed.
By the way, if you somehow disable assertion there, then what would happen with assertion in your own code. Assertion is a tool to help make good and correct code. Learn to use them correctly.

This post shouldnt be voted down because it is important that beginner programmers understand why DEBUG ASSERTS must be resolved.
mackel90, you really need to learn to program properly. And so do your colleagues who put this project together. Read the other good comments here, and think very very carefully about what is being said.
YOU MUST RESOLVE THESES DEBUG ASSERTS BEFORE YOU BUILD A RELEASE VERSION.
It is also good practice to back up a DEBUG ASSERT with a line of code that checks the same thing and exits the func so in release mode you have the same level of protection.
==============================
Nothing to say.

Take my opinion as a pointer, not a definite answer.
Most likely you are doing something with one of your controls when it is not loaded/initialized yet. For example, say you have a dialogbox named CMainDlg. Now If you try to set text of an editbox in CMainDlg's constructor like this
CMainDlg::CMainDlg(CWnd* pParent ): CDialogEx(CAccountDlg::IDD, pParent)
{
GetDlgItem(IDC_TEXT1)->SetWindowText("Debug Assertion");
}
then a debug assertion will be shown. A better way will be do this in OnInitDialog like this (or in an event handler, bound with a button)
BOOL CMainDlg::OnInitDialog()
{
GetDlgItem(IDC_TEXT1)->SetWindowText(" No Debug Assertion");
}
So out and out, you are doing a right thing in a wrong way. Hope you understand what I mean 
This world is going to explode due to international politics, SOON.

No, you just think it is working nicely. The problems just haven't shown themselves visibly yet.

The foresight of that thought sure seems to be an oxy-moron in hindsight
I want to get my work done quickly today, so I can triple my work tomorrow.
I still don't understand how the current release version can work perfectly, unless he broke the project and can't fix it, or the current release version was never fully tested, and it really doesn't work perfectly.
Perhaps the OP is having a really bad day, and is ready to go postal.

Hi,
I am running derived CAsynSocket class inside a CWinThread Class
I am looking to see if a connection status is still up
would running ping utility durning thr CWinThread::OnIdle do the trick
Thanks
|

Do not run the ping utility.
ping.exe is an external file that can be deleted and then your objective will fail.
Instead, send a special packet or use a separate socket to send a packet in the OnIdle function or in a timer event.

No, do not use Ping and do not rely on running it in OnIdle(), you should use a timer.
There are several ways a TCP link can "break" without both sides being properly notified, especially over the Internet, but even on a LAN. If it is important to you to have reliable, persistent links and you have control over the server side code, I suggest you define a keep-alive mechanism.
There are many, many ways of doing this. Over the years I have found the following approach to be sufficient just about anywhere I use persistent TCP connections.
- Determine which side will be sending data the most. Let's call that side A, the other side is side B. Depending on the nature of your applications, side A can be either the server or the client.
- Determine the maximum time a link can be down before reacting to it - 1 second, 10 seconds, 30 seconds, etc. Let's call that T. You do not want to flood the network with these messages, so go as high as you can.
While connected:
- Side A must keep track of the last time a message (data or keep-alive) was sent. If more than T/3 seconds have passed since a message was sent, send a keep-alive message. If the link has gone down, the socket send operation will fail and the program has to react to it.
- Side B must keep track of the last time a message (data or keep-alive) was received. If more than T seconds have passed since a message was received, consider the link down and react to it.

what is operator overloading and how it works with code.
|
|
|
|
|
|
it refers to providing additional meaning to normal c++ operators when they are applied to user defined data types

I want into MDI application to open an menu item on OnLButtonDblClk on client zone in CMainFrame ... so I mapped CMainFrame::OnLButtonDblClk :
void CMainFrame::OnLButtonDblClk(UINT nFlags, CPoint point)
{
TRACE("OnLButtonDblClk\n");
CMDIFrameWnd::OnLButtonDblClk(nFlags, point);
}
but I had an suprise ! I didn't see any TRACE on my doubleclick ... why ?

It's a long time since I did any MFC but do you need to add something to your message map?
|
|
|
|
|
The wizzard did that :
BEGIN_MESSAGE_MAP(CMainFrame, CMDIFrameWnd)
ON_WM_LBUTTONDBLCLK()
END_MESSAGE_MAP()
|
|
|
|
|
Well, as I said, it's been a long time, but I always found the wizard code tended to work 'out of the box', so I cannot see why it would not call the connected function as expected.
|
|
|
|
|
That's why seems to me weird ... I only want to do something on double-click on client area of mainframe ...
|
|
|
|

You could try checking with your debugger that your window class fulfils the requirements specified here[^]. Other than that, lots of breakpoints and single stepping through code seems to be the path you must follow.
|
|
|
|

The client area consists of the view.
That's the reason why the control flow does not enter the OnLButtonDblClk handler of the frame class.
You will need to create a handler for OnLButtonDblClk in the view class.
However, you can create a handler for OnNcLButtonDblClk in the frame class where the double click on an area outside the view will be handled like the edges of the window, title bar, menu bar etc.
|
|
|
|
|
I try that, and does function where you said : menu area, etc. ... I need to know if the user fire double-click between those areas ... right near client area, I mean in dark area of CMainFrame ...
|
|
|
|
|
I don't think you will get double click messeages in the dark area.
You will however be able to trap the WM_LBUTTONDOWN message in the PreTranslateMessage override in the main frame class.
|
|
|
|
|
Good ideea, I will try tomorow ... thank you.
|
|
|
|
|
I try in follow way :
BOOL CMainFrame::PreTranslateMessage(MSG* pMsg)
{
if(pMsg->message == WM_LBUTTONDBLCLK)TRACE("OnDblClick - PreTranslateMessage\n");
return CMDIFrameWnd::PreTranslateMessage(pMsg);
}
but I don't see any traces when I double-click on darrk area of mainframe ... only in CView client area ...
