|
|
|
1472 (Knowledge Base Q130667, PRB: F12 Causes Hard-Coded Breakpoint
|
|
|
1473 Exception When Debugging)
|
|
|
1474
|
|
|
1475 CAUSE
|
|
|
1476
|
|
|
1477 When the F12 key is pressed and the application in focus is being
|
|
|
1478 debugged, Windows NT calls a function similar to DebugBreak(),
|
|
|
1479 which executes a hard coded breakpoint instruction. The integrated
|
|
|
1480 debugger then traps the exception generated by this instruction.
|
|
|
1481
|
|
|
1482 This behavior is intentional and occurs with other debuggers such
|
|
|
1483 as WinDbg from the Windows 32-bit SDK.
|
|
|
1484
|
|
|
1485 RESOLUTION
|
|
|
1486
|
|
|
1487 While there is no way to disable this functionality, it doesn't
|
|
|
1488 affect the application that's being debugged other than to pause
|
|
|
1489 debugging and change focus. You can continue debugging by pressing
|
|
|
1490 the F5 key.
|
|
|
1491
|
|
|
1492 This can be annoying if you have an application that heavily uses
|
|
|
1493 the F12 key, so you may want to temporarily assign another key to
|
|
|
1494 handle the F12 key functionality in your program when debugging.
|
|
|
1495
|
|
|
1496 STATUS
|
|
|
1497
|
|
|
1498 This behavior is by design.
|
|
|
1499
|
|
|
1500
|
|
|
1501 However, elsewhere I found this:
|
|
|

|
|
|
1503 UserDebuggerHotKey

1508
|
|
|
1509 Description
|
|
|
1510
|
|
|
1511 Specifies the key that, when pressed, establishes a breakpoint in
|
|
|
1512 code being debugged.
|
|
|
1513
|
|
|
1514 The debugger interrupts code processing at the breakpoint so the
|
|
|
1515 programmer can examine a suspected problem.
|
|
|
1516
|
|
|
1517 The key specified in this value only sets a breakpoint. It does
|
|
|
1518 not invoke the debugger (the debugger must be running before the
|
|
|
1519 key is pressed) and it does not switch the debugger to single-step
|
|
|
1520 mode.
|
|
|
1521
|
|
|
1522 The value of this entry is a keyboard scan code. The default
|
|
|
1523 value, 0x0, represents the F12 key on a 101-key keyboard or the -
|
|
|
1524 (hyphen, VK_SUBTRACT) key on an 82-key keyboard.

|
|

2574 definitely invoked from TO_INTERNAL_FORMAT().) If we do

2575 this recursively anywhere in the following code, it will
|

2581 triggered only every 1/4 second, why is it getting

2582 consistently triggered here? I saw the problem
|
|
|
2583 consistently. Answer: It appears that, currently,
|
|
|
2584 sometimes the code to pump messages is wrapped with
|
|
|
2585 begin_dont_check_for_quit() and sometimes it isn't. (####
|
|
|
2586 FIX THIS SHIT!) cmdloop.c, for example, has it, but not
|
|
|
2587 everywhere. The current games with avoiding QUIT mean that
|
|
|
2588 the 1/4-second timer consistently fires while
|
|
|
2589 dont_check_for_quit is set [which causes the quit check to
|
|
|
2590 get deferred but the flag is still on], and so the next
|
|
|
2591 time it's unset and we call QUIT is *right here*.
|
|
|
2592
|
|
|
2593 In my stderr-proc ws I majorly cleaned up the whole shit by
|
|
|
2594 just wrapping all the entry points in dont_check_for_quit.
|
|
|
2595 This fixed the remaining bugs with C-g getting interpreted
|
|
|
2596 wrong.)

2598 #### We should probably wrap this whole function in

2599 begin_dont_check_for_quit(); but then we should set this

|
2600 back to 0 when handling a menu callback, which gets invoked
|
|
|
2601 from within this function, specifically from

3713 Note the following in the docs:
|
|
|
3714
|
|
|
3715 Note: The IShellLink interface has an ANSI version
|
|
|
3716 (IShellLinkA) and a Unicode version (IShellLinkW). The
|
|
|
3717 version that will be used depends on whether you compile
|
|
|
3718 for ANSI or Unicode. However, Microsoft® Windows 95 and
|
|
|
3719 Microsoft® Windows 98 only support IShellLinkA.
|
|
|
3720
|
|
|
3721 We haven't yet implemented COM support in the
|
|
|
3722 Unicode-splitting library. I don't quite understand how
|
|
|
3723 COM works yet, but it looks like what's happening is
|
|
|
3724 that the ShellLink class implements both the IShellLinkA
|
|
|
3725 and IShellLinkW interfaces. To make this work at
|
|
|
3726 run-time, we have to do something like this:
|
|
|
3727
|
|
|
3728 -- define a new interface qxeIShellLink that uses
|
|
|
3729 Extbyte * instead of LPSTR or LPWSTR. (not totally
|
|
|
3730 necessary since Extbyte * == LPSTR).
|
|
|
3731
|
|
|
3732 -- define a new class qxeShellLink that implements
|
|
|
3733 qxeIShellLink. the methods on this class need to create
|
|
|
3734 a shadow ShellLink object to do all the real work, and
|
|
|
3735 call the corresponding function from either the
|
|
|
3736 IShellLinkA or IShellLinkW interfaces on this object,
|
|
|
3737 depending on whether XEUNICODE_P is defined.
|
|
|
3738
|
|
|
3739 -- with appropriate preprocessor magic, of course, we
|
|
|
3740 could make things appear transparent; but we've decided
|
|
|
3741 not to do preprocessor magic for the moment.
