Hi,
I am using the following code for years without any complaints. It is used by me in many apps, and included in libs, too many to count.
Always worked a dream.
It concerns an MFC Type CProgressDlg Base Class. A User would derrive his own class thereof, Set a Workerthread function, and the thing takes off as expected.
Here is the Header

Now, all works well in my latest App, until I want to End the Dialog.
All goes well,
CProgressDlg::EndDialog(int ExitCode)
is called, SendMessage calls OnEndDialog(...), which terminates successfully, and then the App terminates with an Exception.
In case you ask, why not trace and debug, the App behaves as expected in Debug Mode, I get this behaviuor only in the Retail version.
I got this far by setting 'StillAlive' traps in the retail version, and do not know how to get further.

Debug the retail version. Build it with debug information and proceed as normal. Debug don't really care if it's a release or debug build.

Did that.
It bombs somewhere in the bowels of USER32.DLL (for which I have NO code) as soon as I link with the MFC Retail Libs. It does this in One App only. I rebuilt another 5 Apps using Identical Code and Calling sequence, and it works fine.

Using SendMessage api thrown from same thread to same thread is problem in itself because SendMessage api is blocking call, better use PostMessage.

I'm not sure what you mean exactly, but using SendMessage to send a message to the same thread as the sender is fine (in fact it's the most common case).

ThatsAlok Using SendMessage api thrown from same thread to same thread is problem in itself because SendMessage api is blocking call
No!
The Doccumentation states clearly that SendMessage calls the WinProc immediately when called from the same thread.
This is what Windows itself does the whole time in a Single Threaded App.

I doubt about this line. You will probably need to handle both the params from SendMessage. i.e. WPARAM, LPARAM.
Also
Bram van Kampen wrote: WM_ENDDIALOG=WM_USER+1,
Not recommended as these values are already used by windows for some other messages. But I don't think it will cause the problem you are facing.

No, The use of the Params is optional. At Any rate, SendMessage lands safely at the handler. It trashes when SendMessage returns.

Well, what would you reccommend instead. It could not be the problem, because SendMessage lands at the correct Handler.
Thanks

Yes, that is why i feel its the parameter issue. You can read more about it here[^] in the parameter counts section.

Also i said it is not the problem just not recommended. About this you can read here[^]
I hope it helps.

Humble Pie is being eaten here.
It was a Parameter issue. Entered a dummy int, and problem is gone.
It baffles me however that this does not seem to affect the Debug Mode.
Thanks to everybody for their invaluable help and Comments.

Stupid question, but does the exception give any further clues? It's some time since I used MFC but I recall that some windows need to be disposed in a different way in the desstructors.
It's time for a new signature.

Well, it fails on an Access error. Why was not clear, but See above.

Hello all,
i know it's a newbie question but i couldn't find a replic or a sample code for such stuf.
I have a CFormView Class and a CTest Class Derived CEdit Class.
on both of them i have the OnKeyDown function, but what i want to do is to call the OnKeyDown fucnt of the deriver CEdit Class from the first one..
I declared a var with CTest var on the CFormView class and in the ONKeyDown (of the CFormView i did like this
void CMy01View::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)
{
this->cd2.OnKeyDown(nChar, nRepCnt, nFlags);
}
and here the one of the CTest Class
void CTest::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)
{
MessageBox("Blood 2");
CEdit::OnKeyDown(nChar, nRepCnt, nFlags);
}
All go right but when i run it nothing will happen ?? how could i fix it ?? Thnk you

Did you add ON_WM_KEYDOWN to your CEdit derived classes message map?
Did you use DDX_Control to bind the edit control in the dialogue template to the instance of CTest in your Form View? I've just realised I didn't mention this when I suggested you implement a derived class of CEdit.
Cheers,
Ash
PS: I know this is complicated, hang in there!

@ Garth: Sorry for deleting the message, i thought it was like in other forums when it's solved we may delete it to avoid the dump.
@ Aescleal: I found a wasty manner to solve my prob (OnKeyDown related) which is
void CSdiView::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)
{
if((nChar<=0x30)&& (nChar>= 0x39))
AfxMessageBox("Number");
CFormView::OnKeyDown(nChar, nRepCnt, nFlags);
}
BOOL CSdiView::PreTranslateMessage(MSG* pMsg)
{
BOOL bHandleNow = false;
switch (pMsg->message)
{
case WM_KEYDOWN:
switch (pMsg->wParam)
{
case 0x39:
case 0x38:
case 0x37:
case 0x36:
case 0x35:
case 0x34:
case 0x33:
case 0x32:
case 0x31:
case 0x30:
bHandleNow = TRUE;
break;
}
if (bHandleNow)
OnKeyDown(pMsg->wParam, LOWORD(pMsg->lParam), HIWORD(pMsg->lParam));
break;
}
return bHandleNow;
}
but i m only able to detected Numbers and Upper Cases Letters like A-Z and no a-z (another problem but at least i was able to detetect numbers an capital letters

Hi
I have been searching the forum for a while now, but haven't found an answer for my question.
When I write code in C++, I seperate methods and such with blank lines. Thus dividing them into logical groups.
Well I do this in every language I write code in, but C++ is giving me a hard time with this. When I collapse the methods, it will also include my blank lines. I know I can use regions to do this, but since C# and VB do not have this behavior, I was wondering. Is this a certain setting in Visual studio or is het just a crappy way of making the layout? I'm using the express by the way.
Thanks in advance
Steven

Same here, except I use a commented row of '=' characters.

I use (have used) express editions of VC++ 2005, 2008 and now 2010 and none of them exhibit the behaviour you describe (if I understand correctly). If I have a method followed by a blank line, when I collapse the method the blank line is still visible.
It's time for a new signature.
