(I always set Execution option, but ignore the Continue option before.)
Do a search on "Controlling Exceptions and Events" in WinDBG's help file. I have quoted from this below.
The radio buttons in the "Execution" group control the "Break Status":
- Enabled : "When this exception occurs, the target immediately breaks into the debugger. This break in occurs before any other error handlers are activated. This method is called first-chance handling."
- Disabled : "The debugger does not break in for this kind of first-chance exception (although a message is displayed). If other error handlers cannot address this exception, execution stops and the target break into the debugger. This method is called second-chance handling."
- Notify : "When this exception occurs, the target application does not break into the debugger at all. However, a message is displayed that informs the user of this exception."
- Ignore : "When this exception occurs, the target application does not break into the debugger, and no message is displayed."
The buttons in the "Continue" group control the "Handling Status":
- Handled : "The event is considered handled when execution resumes."
- Not Handled : "The event is considered not handled when execution resumes."

Thanks Steve,
I think the question for C++ exception is solved. For the managed code, why the line number could not be displayed when using !pe command, I am not sure whether it is supported in managed code to print the line number along with !pe command output. Any comments?
regards,
George

Sorry, I can't really help you there. I try to steer clear of managed code: it simply doesn't interest me.

It is ok, Steve!
I am trying to find help for command !wow64exts.sw in debugger.chm, but failed. Do you have any documents for this command?

Not really. Try typing !wow64exts.help

What is the simplest way to change font of MDI? For example I want a menu with bold, Arial, size 10 font.
Create a menu and use SetFont() function seem to be a official way, but actually it doesn't work.
I found some articles by Google but not help much.

Setting Fonts for Menu-Item Text Strings
This topic contains an example from an application that uses owner-drawn menu items in a menu. The menu contains items that set the attributes of the current font, and the items are displayed using the appropriate font attribute.
Here is how the menu is defined in the resource-definition file. Note that the strings for the Regular, Bold, Italic, and Underline menu items are assigned at run time, so their strings are empty in the resource-definition file.
MainMenu MENU
BEGIN
POPUP "&Character"
BEGIN
MENUITEM "", IDM_REGULAR
MENUITEM SEPARATOR
MENUITEM "", IDM_BOLD
MENUITEM "", IDM_ITALIC
MENUITEM "", IDM_ULINE
END
END
The application's window procedure processes the messages involved in using owner-drawn menu items. The application uses the WM_CREATE message to do the following:
Set the MF_OWNERDRAW flag for the menu items.
Set the text strings for the menu items.
Obtain handles of the fonts used to draw the items.
Obtain the text and background color values for selected menu items.
The text strings and font handles are stored in an array of application-defined MYITEM structures. The application-defined GetAFont function creates a font that corresponds to the specified font attribute and returns a handle to the font. The handles are destroyed during the processing of the WM_DESTROY message.
During the processing of the WM_MEASUREITEM message, the example gets the width and height of a menu-item string and copies these values into the MEASUREITEMSTRUCT structure. The system uses the width and height values to calculate the size of the menu.
During the processing of the WM_DRAWITEM message, the menu item's string is drawn with room left next to the string for the check-mark bitmap. If the user selects the item, the selected text and background colors are used to draw the item.

It seem to be not very easy. I'll try it later.
Thank you very much, halibobo.

There is no easy way. The menu is part of the non-client area, and windows is kindly handling for you.
The idea is that a user can pick a font / size she likes, and all her software will use it. You'd better have a damn good reason to override her preferences, so it's fine for it to be hard for you.
There are several good owner drawn menu articles here on codeproject for you to dig through, or look at halibobo's reply.

When using an STL with iterators, what is the right way to determine if the iterator is valid? Start with:
Vector < CMyClass * > MyList;
Vector < CMyClass * >::iterator Iter_1;
Vector < CMyClass * >::iterator Iter_2;
The program creates object of type CMyClass and puts pointers to those objects in the container. The program will compare various objects in the container with other objects, hence the need for two iterators.
For various reasons, either of the iterators might not be valid at any given time. If not, then I want to do Iter_1.begin(). If the iterator is valid, I don’t want to reset it. What test should be done to determine if it is valid?
If I delete an item that an iterator is referencing, is it valid to increment or decrement the iterator to get to either the next item in the list or the end of the list?
Thanks for your time

There is no portable way to tell if an iterator is valid.

Hi, I'm trying to alter control properties at runtime.
I've got two images in a Picture Control (BMP) and I only want one visible at a time as they will overlap. I'm already animating them but I only want to see one Animation Frame at a time.
So, how can I set properties of controls at runtime? (I've already got control variables attached.)
Pointing out articles to me would also suffice.
thanks for your time,

Same old noise, different day.  At this point I don't believe it will improve, it might get worse I suppose.
Have you seen Graus's new article[^]? This is what we have come to! It gave me an idea for new Article, ok, an idea for an article title, "If you're an idiot go away". If they don't know how to determine that, they can ask in the forum for the article.

Hello to all,
i am working to develop a media player in MFC. I am useing the FMODCE library to play the audio files. The problem is that the FSOUND_Stream_Open( "File name") function takes very large time to open the .MP# file format. So bcoze of this i seems that the application is going to halt.
Can any body help/guide me to overcome this difficulty. Or can tell me any other function/library to play .mp3, .wav,midi format file more accurately / and fastly. I shall be very thankful to all of u.
thanx in Advance.

Wouldn't the fmod forums be a more appropriate place to ask about this?

i am guessing u are using the FSOUND_MPEGACCURATE mode?
if so just read the file into memory first then use FSOUND_LOADMEMORY mode instead.
might help maybe
