C++ Exceptions and Catch-All Handlers TheGlynn2-Jul-03 5:30 TheGlynn 2-Jul-03 5:30  I am using try{}catch(...) handlers extensively to handle all types of exceptions that are thrown. In particular, I am catching hardware exceptions such as access violations and so on. How can I find out exactly what hardware exception occurred within the catch(...) handler? Do I have to use SEH to do this? Re: C++ Exceptions and Catch-All Handlers jhwurmbach2-Jul-03 5:41 jhwurmbach 2-Jul-03 5:41  Does std::exception::what() help you? Or do you need to differtiate the exception objects at runtime and react on their type? Then typeid may help you (look for RTTI in MSDN)to determine the type of the exception-object you caught. But maybe you simply can replace the catch(...) with a list of catches for the exception classes you need. My opinions may have changed, but not the fact that I am right.

Within the constructor I make a new object and I can access the data members. When I try to access them in different member functions however I get memory access errors. I call the delete in the destructor, and not before. I'm not sure what is wrong. Re: Heap Dean Goodman2-Jul-03 5:40 Dean Goodman 2-Jul-03 5:40  Could you post your code?

By declaring the m_pParticles variable again in the init() function, you have made a new variable that only has scope in the init() function, and happens to be named the same as your member variable m_pParticles. Thus the member variable never gets assigned, and you (rightfully) get memory errors when you later try and delete it. --Dean Re: Heap Ken Mazaika2-Jul-03 7:39 Ken Mazaika 2-Jul-03 7:39  Excellent. Thanks a bunch!

I have a CAxDialogImpl modal dialog created using a dialog I created. Let us call it CMyDialog. I set the caption in CMyDialog's resource editor. The dialog style is Overlapping and Resizing. Everything is right with the world. When the dialog is created via CAxDialogImpl<cmydialog>::DoModal, the caption in the resource is, predictably, displayed. But now I want to change the caption of the dialog dynamically when the dialog is created ( It is instantiated from another dialog ). I modify the OnShowWindow function so that I may change the caption with SetWindowText(). Guess what; though the function returns success, the caption does not change. I want to change the caption. SetWindowText isn't doing it. Anyone got any ideas? A grateful person awaits your learned replies. "Never play drinking games with coffee." Re: Editing Title Bar Captions David Crow2-Jul-03 10:26 David Crow 2-Jul-03 10:26  Set the dialog's caption in OnInitDialog(). Re: Editing Title Bar Captions Captain Apathy2-Jul-03 10:44 Captain Apathy 2-Jul-03 10:44  I discovered the problem; a previously overwritten WS_SETTEXT command. Thanks for the suggestion, though.
