OK,
If I simplify the situation the following happes:
diag2 : diag2.DoModal
diag2 : do some work etc...
diag2 : when ready (or user presses cancel) EndDialog()
or
diag2 : when ready (or user presses cancel) OnCancel()
|
|
|
|
|
Is it like this ??
In Dlgdiag2.cpp
CDlgdiag2::OnSomeAction()
{
CDlgdiag2 diag2;
diag2.DoModal();
}
CDlgDiag2::OnCancel()
{
EndDialog();
OR
OnCancel();
}

It is:
CDlgdiag1::OnSomeAction()
{
CDlgdiag2 diag2;
diag2.DoModal();
}
CDlgDiag2::OnCancel()
{
EndDialog();
OR
OnCancel();
}

If you are calling OnCancel(), you are in trouble. It will take you to an infinite loop. So you should be using CDialog::OnCancel()
I know, thats not the problem you are facing. But apart from that, I just can't find anything odd in this piece of code. You can do one thing. As I have suggested earlier put a breakpoint in
CDlgDiag2::OnCancel()
{
EndDialog(); //HERE
}
put another break point in
CDlgdiag1::OnSomeAction()
{
CDlgdiag2 diag2;
diag2.DoModal();
} // HERE
run the program in DEBUG mode( press F5 ), and then press the Cancel button, then you will be in EndDialog fn. press F5 again, then either the control will reach the 2nd break point, or else it will ASSERT. When it ASSERTs, right click anywhere on the toolbar and select the 'CallStack' option. If you are not getting any idea on what it is, just dump it here, so that we can have a look at where its going wrong.
Another thing I noticed is, wincore.cpp has only 3948 lines. How come you got an error in 4198 ?

If possible, post the code.
OR
you can use CallStack( Right click anywhere on the toolbar, and select CallStack ) in debug mode to see how the control reached wincore

Strange as wincore.cpp does not have that many lines. Are you using VS6 or VS.NET?

I was also little bit confused!!!

Hi,
I've got a listBox in a program, and an array of instances of an own class. This class has a property called ID, and name. Both can be accessed by using get_ID(), and get_name(). The user must be able to select an instance in the listbox by selcting its name and clicking a button.
This works, I use getCurSel, as long as I know what position each instance has in the list. But other people will need to add their own instances, and they will have to change all the ID's etc.
Is there a way to determine the text selected in a list box, instead of the position of the selection, so I will know exactly which instance is selected?
Thanks,
|

The way that I use is when I add a string to the list box, I also setup a pointer to the custom data, in your case, your own class. I usually do this with:
m_ListBox.SetItemDataPtr (m_ListBox.AddString (item->name), (void *)item);
You can then get the item data for the current selection like so:
my_class *item = (my_class *)m_ListBox.GetItemDataPtr (m_ListBox.GetCurSel ());
Does this help?

You can use the CListBox::GetText method. GetText accepts the position and LPSTR as input, and you can pass the selected item position, and get the corresponding text.
pListBox->GetText( position, str.GetBuffer(MAX_LENGTH) );

Is DirectX available to .NET framework? If not, is there any plan to make it available yet?

Yes it is available... rather I programmed some programs in C#... You can download DirectX SDK from Microsoft.com
DirectX 9.0 Software Development Kit (SDK) for C#

Hi
Can someone know a library wich is used to convert hexadecimal numbers to integers (I know how to do this, but I don't have time to wirte it myself). I just need an open-source function.
Thanks

I think you might mean hexadecimal strings to a number.
The C++ library function, strtol() will do the job for you.
Or _tcstol() for the UNICODE compatible function.
long wcstol( const wchar_t *nptr, wchar_t **endptr, int base );
You just need to specify the base, in your case this would be 16.
I Dream of Absolute Zero

the question is kinda bad!
what do u need the conversion for?
hexadecimal to (int)string or what?
Don't try it, just do it!

Hi currently i use MSComm32.ocx control i just try to pass data into comm port ,i open port and send data by using
mptr->PutOutput("text"); simple text all fine not any error
arised.But when i try to pass binary data this way
byte bt[] = {1,2,3};
VARIANT vt;
vt.vt = VT_BYREF | VT_UI1;
vt.pbVal = bt;
mptr->PutOutput(vt);
Run time error hr = -2146827908 (Unknown error)!!!
I guess this trouble arised because of i unproperly created vt variable.
And by the way how i can properly create any pointers in variant type??? I think
first step is create array with neccesary values
byte bt[] = {1,2,3};
,second step copy this array to variant union
vt.pbVal = bt;
and third step defint through vt member of VARIANT this type
vt.vt = VT_BYREF | VT_UI1;
Its enought???
How compiler recognized how much ellements on array into passed VARIANT structure???This only pointers and one cant do it i thought???
Sorry for bad Eanglish.

Hi
I am tryin to load a TLB file in my project. It is physically present on the disk and is included in INCLUDES and LIBRARY FILES variables of environment. In simple words all is good but compiler is generating following error...
fatal error C1084: Cannot read type library file: 'QTSLimits.tlb': Error loading type library/DLL.
But when I remove that TLB file, error becomes obvious...
fatal error C1083: Cannot open type library file: 'QTSLimits.tlb': No such file or directory
I thought that TLB file is corrupt, but I have compiled it again and againnnn... ANY SOLUTION?
I am tryin to compile VC++5/6 Code on VC .NET
thanks in advance!

How are you trying to include the type library?

Can you view the Typelibrary through OleView.exe?
This will help to determine whether the type library is valid.

Dear All,
I am developing an application using MFC VC++ Version 6.0 for Windows 2000.
I have made my application run as a service. The application starts with an icon in the System tray. On double clicking the icon the application starts (ie. dialog boxes are displayed, some background operations are performed, etc..)
The application works very fine when i restrat the system i.e. the system tray icon appears and it performs the apporpriate functions . But when i loggoff the system and then loggin, the tray icon is freezed!!!
The tray icon then doesnot responds to the mouse events (double click , single click or right click)
I know that during loggoff the service keeps on running. And the application is performing its background operations also during loggoff, but the tray icon stops responding.
Do I need to refresh the tray icon ???? Or any alternate solution to above problem
Please comment!
Rohit
