I get an access violation in release mode but not in debug.
Yes, I know it's been talked about in many threads and I think I have read all of them. I can even debug release mode now, to impress my colleagues.
It dies when I hop into a dll I wrote, but not always quite in the same place. I have a feeling I have a NULL pointer. Anyway, I have been looking at ways I might be making a null pointer, and have made many improvements, but it still crashes.
HERE is the question...
One of the threads here asked if the poster had code in his constructor. Now I often have code in my constructors, I even call other constructors, with new (and I delete every single one, I promise), and as far as I am concerned this is quite normal and acceptable. Am I wrong? Could this be it? I also put code in destructors, deleting stuff and ending other processes.

I bet you missed this[^] one.
You need to google first, if you have "It's urgent please" mentioned in your question.

No I didn't. That is one of the best ones so far.
(I even bookmarked it.)

I see you have already read Joe's article on surviving the release build. By now, you must be ready to survive the release build, then.

Which implies that the "many improvements" you made were not to the code which was causing the crash. A crude and quick approach would be to add OutputDebugString()[^] statements in the pieces of code that you suspect. This way, you may know until where the control reaches and where does it crash.

Thank you. I do know where it crashes, it enters my little dll through an exported function, then instantiates the class in there, and dies in the constructor, right on the {.
I can tell that its problem is a null or corrupted pointer, because the debugger lets me look at the assembly code, and it tries to jump to places it's not allowed to, an access violation, as it says.
I am trying to get DevPartner to run again. (The newest version seems to be a bit buggy.) When it was running before, it complained about "Calling Virtual Functions from Constructors and Destructors" and stuff like that, which I have stopped doing (this is what I meant by improvements). Hence my question. Is it OK to put code - I mean, real code that does things - in the constructor and destructor, when the compiler allows it and DevPartner whinges about it?
If I can't get it running this week I shall just have to deliver the debug version, which is not so tragic right now, but it bothers me.

Hi all,
please tell me how can SetTimer on Modeless dialog box.
thanks in advance.

not only plan, but also believe.

The same way you set timer for a modal dialog...
|
|

i m trying same method but its not working in case of modeless dialog box.
use
SetTimer(1, 500, NULL);
void CTest_Dlg::OnTimer(UINT_PTR nIDEvent)
{
switch (nIDEvent)
{
case 1:
AfxMessageBox(_T("Timer"));
break;
}
CDialog::OnTimer(nIDEvent);
}
this working fine in modal dialog box.but OnTimer not call in case of modeless dialog box.
please help me for this.
thanks in advance.

It should work fine.... hope your messagemap contains
ON_WM_TIMER() entry. pls check.
|
|
|
|

yes i have ON_WM_TIMER() in my message map.

Since your dialog is modless, who runs the message loop? another dialog?
Try this. Just after the dialog creation put a messagebox...and then check whether the timer is triggered or not...
|

I m already use AfxMessageBox in timer but its never popups.

its ok. Keep that message bo as it is..
I asked you to add another messagebox just after the creation. this to check whether this is as problem of the message loop...
|

Why are you calling AfxMessageBox() from within the timer callback routine? I cannot think of any reason why that would ever be the right thing to do. If you are debugging, use something that does not block (e.g., TRACE()).

Hi
I am looking for a good serialization design which can support multi-inheritance.
If anyone knows a good class, please me know.
Best regards,

Overload the PreCreateWindow() funcion of the editview class, in that add WS_HSCROLL and ES_AUTOHSCROLL.
....::PreCreateWindow(..)
{
lpcs->style |= WS_HSCROLL|ES_AUTOHSCROLL;
.....
}
|
|
|
|

In the Test_View.cpp i h vae the code but it does not work
BOOL CTest_View::PreCreateWindow(CREATESTRUCT->cs)
{
cs.style |= WS_HSCROLL|ES_AUTOHSCROLL;
return CEditView::PreCreateWindow(cs);
}

Hi all,
I have a richedit control in my program (which is unicode compiled). This richedit control refuses to display the ALT+nnn codes. Instead some sort of random junk (boxes) appear after I let go of the alt key and press any other key. I load the "RICHED20.DLL" library. Another fact is that i can paste unicode characters in the control. It is only with the typing, that the control seems to have a problem. Any help will be appreciated. Thanks in advance.

I have written a program (C++/MFC) to obtain the correct time from a time server and set the system clock. Unfortunately, Vista & Win 7 with UAC enabled block this operation. How can I elevate the program's security privledge level so that I can set the clock? Is that the right approach? If not, how else might I go about it? I wouldn't have thought the system time would be that protected, but it obviously is. I am using a Code Project solution CSNTPClient class and the class function CSNTPClient::SetClientTime(CTime newTime) The solution on my own machine is to turn UAC off, but that's not practical or reasonable on other people's computers.
Thanks.
Ron
