|
|
|
1650
|
|
|
1651 When the F12 key is pressed and the application in focus is being
|
|
|
1652 debugged, Windows NT calls a function similar to DebugBreak(),
|
|
|
1653 which executes a hard coded breakpoint instruction. The integrated
|
|
|
1654 debugger then traps the exception generated by this instruction.
|
|
|
1655
|
|
|
1656 This behavior is intentional and occurs with other debuggers such
|
|
|
1657 as WinDbg from the Windows 32-bit SDK.

1661 While there is no way to disable this functionality, it doesn't
|
|
|
1662 affect the application that's being debugged other than to pause
|

1663 debugging and change focus. You can continue debugging by pressing

1664 the F5 key.

1665

|

1666 This can be annoying if you have an application that heavily uses

1667 the F12 key, so you may want to temporarily assign another key to

1668 handle the F12 key functionality in your program when debugging.

1683 Description
|
|
|
1684
|
|
|
1685 Specifies the key that, when pressed, establishes a breakpoint in
|
|
|
1686 code being debugged.
|
|
|
1687
|
|
|
1688 The debugger interrupts code processing at the breakpoint so the
|
|
|
1689 programmer can examine a suspected problem.
|
|
|
1690
|
|
|
1691 The key specified in this value only sets a breakpoint. It does
|
|
|
1692 not invoke the debugger (the debugger must be running before the
|
|
|
1693 key is pressed) and it does not switch the debugger to single-step
|
|
|
1694 mode.
|
|
|
1695
|
|
|
1696 The value of this entry is a keyboard scan code. The default
|
|
|
1697 value, 0x0, represents the F12 key on a 101-key keyboard or the -
|
|
|
1698 (hyphen, VK_SUBTRACT) key on an 82-key keyboard.

|
|

2728 definitely invoked from TO_INTERNAL_FORMAT().) If we do

2729 this recursively anywhere in the following code, it will
|

2735 triggered only every 1/4 second, why is it getting
|
|
|
2736 consistently triggered here? I saw the problem
|
|
|
2737 consistently. Answer: It appears that, currently,
|
|
|
2738 sometimes the code to pump messages is wrapped with
|
|
|
2739 begin_dont_check_for_quit() and sometimes it isn't. (####
|
|
|
2740 FIX THIS SHIT!) cmdloop.c, for example, has it, but not
|
|
|
2741 everywhere. The current games with avoiding QUIT mean that
|
|
|
2742 the 1/4-second timer consistently fires while
|
|
|
2743 dont_check_for_quit is set [which causes the quit check to
|
|
|
2744 get deferred but the flag is still on], and so the next
|
|
|
2745 time it's unset and we call QUIT is *right here*.
|
|
|
2746
|
|
|
2747 In my stderr-proc ws I majorly cleaned up the whole shit by
|
|
|
2748 just wrapping all the entry points in dont_check_for_quit.
|
|
|
2749 This fixed the remaining bugs with C-g getting interpreted
|
|
|
2750 wrong.)
|
|
|
2751
|
|
|
2752 #### We should probably wrap this whole function in
|
|
|
2753 begin_dont_check_for_quit(); but then we should set this
|
|
|
2754 back to 0 when handling a menu callback, which gets invoked
|
|
|
2755 from within this function, specifically from
|
|
|
2756 DefWindowProc(). (We already do the latter in my new

3906 Note the following in the docs:
|
|
|
3907
|
|
|
3908 Note: The IShellLink interface has an ANSI version
|
|
|
3909 (IShellLinkA) and a Unicode version (IShellLinkW). The
|
|
|
3910 version that will be used depends on whether you compile
|
|
|
3911 for ANSI or Unicode. However, Microsoft® Windows 95 and
|
|
|
3912 Microsoft® Windows 98 only support IShellLinkA.
|
|
|
3913
|
|
|
3914 We haven't yet implemented COM support in the
|
|
|
3915 Unicode-splitting library. I don't quite understand how
|
|
|
3916 COM works yet, but it looks like what's happening is
|
|
|
3917 that the ShellLink class implements both the IShellLinkA
|
|
|
3918 and IShellLinkW interfaces. To make this work at
|
|
|
3919 run-time, we have to do something like this:
|
|
|
3920
|
|
|
3921 -- define a new interface qxeIShellLink that uses
|
|
|
3922 Extbyte * instead of LPSTR or LPWSTR. (not totally
|
|
|
3923 necessary since Extbyte * == LPSTR).
|
|
|
3924
|
|
|
3925 -- define a new class qxeShellLink that implements
|
|
|
3926 qxeIShellLink. the methods on this class need to create
|
