Hello everyone,

I am trying the continue function triggered by JIT debugger. As mentioned in
MSDN,

[url]http://msdn2.microsoft.com/zh-cn/library/h22dk1y6(en-us).aspx[/url]

--------------------
Continue
Allows execution to continue, giving the exception handler a chance to
handle the exception. This option is not available for certain types of
exceptions. Continue will allow the application to continue. In a native
application, it will cause the exception to be rethrown. In a managed
application, it will either cause the program to terminate or the exception
to be handled by a hosting application.
--------------------

I write the following program to try this feature and expect when click
continue, the __except code block is executed, but actually even the JIT
debugger is not displayed to let us select debugger. Do you know why and how
to fix it to make it have expected function (when click continue, execute
exception handler code block)?

[Code]
#include "Windows.h"

int main()
{
    int a;
    int b;
    int c;

    __try
    {

        a = 100;
        b = 200;
        c = 300;

        DebugBreak();
        a = 400;

    }
    __except(GetExceptionCode() == EXCEPTION_BREAKPOINT ?
             EXCEPTION_EXECUTE_HANDLER : EXCEPTION_CONTINUE_SEARCH)
    {
        // No debugger is attached, so return FALSE
        // and continue.
        return FALSE;
    }

    return TRUE;
}
[/Code]

thanks in advance,
George
