Yes, you can set conditional breakpoints.
|
|
|
|
|
Yes I know but I cannot use a variable because this is really to complicated (it's things with void pointers that are being cast and stored in a list...). So I cannot set a breakpoint whan a VARIABLE is changing but when a MEMORY BLOCK is changing !
Any ides?

Hiyz,
I wanted to write a winsock 2 layered service provider using the SPI so i downloaded the layered[^] sample at MSDN. But when i install the LSP none of my internet applications work anymore (IE, games etc..). The sample really doesnt do much according to me, its more like a framework i figured. I'm running Windows XP.
Anyone can help me figure out whats wrong?
Thanks.

Hi people,
I've build an app wich uses some screens; all of them work OK, except for one:
If i press the cancel button, is should return to the previous window, but I get this:
"Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call. This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention"
I've just used a Button and a standard switch statement, both the sending class and the returning one are derived from CDialog!
Can someone tell me what i wrong with this?

Only if you give more info - just show a few lines of code, e.g. the function where the error hits.

There you are: 
The bold big italic code is where the prgram syas it crashes (it seems strange)
CF2FDlg is the first screen, wich calles the second (and other...) wich is IOschermclass, and is also the one wich must be shown after clicking cancel in the IOschermclass
void CF2FDlg::ga_naar_IOscherm(Cmodeprop C)
{
IOschermclass *iosclass= new IOschermclass();
INT_PTR nRet = -1;
nRet=iosclass->DoModal();
switch(nRet)
{
case IDCANCEL:
{
return;
}
case IDC_stop:
{
break;
}
case 1:
{
return;
}
default:
{
return;
}
};
return;
}
void IOschermclass::OnBnClickedTerug()
{
EndDialog(ID_TERUG);
}
BEGIN_MESSAGE_MAP(IOschermclass, CDialog)
ON_BN_CLICKED(IDC_BUTTON1, OnBnClickedButton1)
ON_BN_CLICKED(IDC_BUTTON2, OnBnClickedButton2)
ON_BN_CLICKED(IDCANCEL, OnBnClickedCancel)
ON_BN_CLICKED(IDOK_IOscherm, OnBnClickedIoscherm)
//ON_BN_CLICKED(IDCANCEL2, OnBnClickedCancel2)
ON_BN_CLICKED(IDC_CHECK, OnBnClickedCheck)
ON_BN_CLICKED(IDC_BUTTON3, OnBnClickedButton3)
ON_STN_CLICKED(ID_outpad, OnStnClickedoutpad)
ON_COMMAND(IDOK_IOscherm,OnBnClickedIoscherm)
//ON_COMMAND(ID_TERUG,OnBnClickedTerug)
ON_BN_CLICKED(ID_TERUG, OnBnClickedTerug)
ON_STN_CLICKED(ID_inpad, OnStnClickedinpad)
ON_BN_CLICKED(IDC_stop, OnBnClickedstop)
ON_COMMAND(IDC_stop,OnBnClickedstop)
END_MESSAGE_MAP()

Some annotations to your code:
A) Where is the delete corresponding to your new. These need to come in pairs!
As it is now, you probably have a memory leak: After iosclass has gone out of scope, there is no way you can ever call delete on it.
But maybe you are doing a delete this inside of the class?
B) nRet only needs to be of type int, not INT_PTR. That you are calling DoModal() via a pointer does not change its return type.
Otherwise, it looks OK. I am puzzled here why this should not work.
Check for nRet geting assigned ID_TERUG and step through the switch/case.

Ok, Il'll give it a try.
A) I didn't use delete --> variables will go out of of scope automatically, and I do not (as far as I know) have any memory problems
B) is it really, I got the INT_PTR form an MSDN example --> first I used an int too, but after I saw the example I thought it might be better to use an INT_PTR
Thanks

Looking at the error code again:
"Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call. This is usually a result of calling a function declared
with one calling convention with a function pointer declared with a different calling
convention" I begin to suspect that you have confused the compiler by changing some of the
ON_... stuff that the CodeWizard produces by hand.
That way the ON_... macros may produce wrong code.
Hope this helps

Here are my ON_COMMAND's etc:
BEGIN_MESSAGE_MAP(IOschermclass, CDialog)
ON_BN_CLICKED(IDC_BUTTON1, OnBnClickedButton1)
ON_BN_CLICKED(IDC_BUTTON2, OnBnClickedButton2)
ON_BN_CLICKED(IDCANCEL, OnBnClickedCancel)
ON_BN_CLICKED(IDOK_IOscherm, OnBnClickedIoscherm)
//ON_BN_CLICKED(IDCANCEL2, OnBnClickedCancel2)
ON_BN_CLICKED(IDC_CHECK, OnBnClickedCheck)
ON_BN_CLICKED(IDC_BUTTON3, OnBnClickedButton3)
ON_STN_CLICKED(ID_outpad, OnStnClickedoutpad)
ON_COMMAND(IDOK_IOscherm,OnBnClickedIoscherm)
//ON_COMMAND(ID_TERUG,OnBnClickedTerug)
ON_BN_CLICKED(ID_TERUG, OnBnClickedTerug)
ON_STN_CLICKED(ID_inpad, OnStnClickedinpad)
ON_BN_CLICKED(IDC_stop, OnBnClickedstop)
ON_COMMAND(IDC_stop,OnBnClickedstop)
END_MESSAGE_MAP()
It's exact the same as in other parts of my app, but it doesn't work!!!!!

Post the declarations of those functions, in your class's header file

OK, here is how it works with me:
GeneralPP, derived from a CPropertyPage, contains a button to show a CAdvProcDlg, derived from CDialog.
After closing CAdvProcDlg, you can then proceed to use GeneralPP or even call CAdvProcDlg again.
In my case, there is no need to call EndDialog() in CAdvProcDlg, I only use IDOK and IDCANCEL.
void CGeneralPP::OnButtonProcAdvanced()
{
CAdvProcDlg dlg;
int result = dlg.DoModal();
if (result != IDOK)
{
if (result!=IDCANCEL)
{
TRACE1("CAdvProcDlg ended with %d", result);
}
}
else
{
}
} [EDIT]
Please not the function signature of my OnButtonProcAdvanced() function: return type void, parameter list void, too. This may very well make the difference?

Hello,
Did you port some old code written in a different language that are not part of a standard library? If so, and they are called from IOschermclass, try not to call those.
The is a tiny change that this will help you getting closer to the source of your problem...
A student knows little about a lot.
A professor knows a lot about little.
I know everything about nothing.
|
|
|
|
|
No,
it's all fesh, brand new code, written in MFC C++ in vStudio .NET 2003
|
|
|
|
|
If you press other bottons on the dialog, do you get the same error?
jij bent trouwens de eerste nederlander die ik hier tegenkom

No, i don't get the same error : it's unique
Nee hoor, ik krijg niet dezelfde error, dit gebeurt alleen bij die specfieke knop.
|
|
|

Post the code for the OnCancel() method, the problem probably lies there

I mean the OnBnClickedCancel() method,...
A student knows little about a lot.

I know everything about nothing.
|
|
|
|
|
it's just EndDialog(IDCANCEL);
|
|
|
|
|
When I look at the declaration of EndDialog, you are missing a parameter! (from the msdn library: BOOL EndDialog(HWND hDlg, INT_PTR nResult);)
but let's get something straight:
When you press the cancel button, OnBnClickedCancel() is called.
From there you call EndDialog().
Assuming this, maybe you should call CDialog::OnCancel(). The EndDialog function just ends the message loop returning control to the system, maybe something goes wrong there.

OK,
