1456 When running under a debugger, every time I hit F12 (which for me

1465 Microsoft says:
|

|
1466
|
|
|
1467 (Knowledge Base Q130667, PRB: F12 Causes Hard-Coded Breakpoint
|
|
|
1468 Exception When Debugging)
|
|
|
1469
|
|
|
1470 CAUSE
|
|
|
1471
|
|
|
1472 When the F12 key is pressed and the application in focus is being
|
|
|
1473 debugged, Windows NT calls a function similar to DebugBreak(),
|
|
|
1474 which executes a hard coded breakpoint instruction. The integrated
|
|
|
1475 debugger then traps the exception generated by this instruction.
|
|
|
1476
|
|
|
1477 This behavior is intentional and occurs with other debuggers such
|
|
|
1478 as WinDbg from the Windows 32-bit SDK.
|
|
|
1479
|
|
|
1480 RESOLUTION
|
|
|
1481
|
|
|
1482 While there is no way to disable this functionality, it doesn't
|
|
|
1483 affect the application that's being debugged other than to pause
|
|
|
1484 debugging and change focus. You can continue debugging by pressing
|
|
|
1485 the F5 key.
|
|
|
1486
|
|
|
1487 This can be annoying if you have an application that heavily uses
|
|
|
1488 the F12 key, so you may want to temporarily assign another key to
|
|
|
1489 handle the F12 key functionality in your program when debugging.
|
|
|
1490
|
|
|
1491 STATUS
|
|
|
1492
|
|
|
1493 This behavior is by design.
|
|
|
1494
|
|
|
1495
|
|
|
1496 However, elsewhere I found this:
|
|
|
1497
|
|
|
1498 UserDebuggerHotKey
|
|
|
1499 HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AeDebug

1500
|
|
|
1501 Data type Range Default value
|
|
|
1502 REG_DWORD 0x0 - 0xFF 0x0
|
|
|
1503
|
|
|
1504 Description
|
|
|
1505
|
|
|
1506 Specifies the key that, when pressed, establishes a breakpoint in
|
|
|
1507 code being debugged.
|
|
|
1508
|
|
|
1509 The debugger interrupts code processing at the breakpoint so the
|
|
|
1510 programmer can examine a suspected problem.
|
|
|
1511
|
|
|
1512 The key specified in this value only sets a breakpoint. It does
|
|
|
1513 not invoke the debugger (the debugger must be running before the
|
|
|
1514 key is pressed) and it does not switch the debugger to single-step
|
|
|
1515 mode.
|
|
|
1516
|
|
|
1517 The value of this entry is a keyboard scan code. The default
|
|
|
1518 value, 0x0, represents the F12 key on a 101-key keyboard or the -
|
|
|
1519 (hyphen, VK_SUBTRACT) key on an 82-key keyboard.

|
|

2564 definitely invoked from TO_INTERNAL_FORMAT().) If we do

2565 this recursively anywhere in the following code, it will
|

2571 triggered only every 1/4 second, why is it getting

2572 consistently triggered here? I saw the problem
|
|
|
2573 consistently. Answer: It appears that, currently,
|
|
|
2574 sometimes the code to pump messages is wrapped with
|
|
|
2575 begin_dont_check_for_quit() and sometimes it isn't. (####
|
|
|
2576 FIX THIS SHIT!) cmdloop.c, for example, has it, but not
|
|
|
2577 everywhere. The current games with avoiding QUIT mean that
|
|
|
2578 the 1/4-second timer consistently fires while
|
|
|
2579 dont_check_for_quit is set [which causes the quit check to
|
|
|
2580 get deferred but the flag is still on], and so the next
|
|
|
2581 time it's unset and we call QUIT is *right here*.
|
|
|
2582
|
|
|
2583 In my stderr-proc ws I majorly cleaned up the whole shit by
|
|
|
2584 just wrapping all the entry points in dont_check_for_quit.
|
|
|
2585 This fixed the remaining bugs with C-g getting interpreted
|
|
|
2586 wrong.)

2588 #### We should probably wrap this whole function in
|

2589 begin_dont_check_for_quit(); but then we should set this

|
2590 back to 0 when handling a menu callback, which gets invoked
|
|
|
2591 from within this function, specifically from

3703 Note the following in the docs:
|
|
|
3704
|
|
|
3705 Note: The IShellLink interface has an ANSI version
|
|
|
3706 (IShellLinkA) and a Unicode version (IShellLinkW). The
|
|
|
3707 version that will be used depends on whether you compile
|
|
|
3708 for ANSI or Unicode. However, Microsoft® Windows 95 and
|
|
|
3709 Microsoft® Windows 98 only support IShellLinkA.
|
|
|
3710
|
|
|
3711 We haven't yet implemented COM support in the
|
|
|
3712 Unicode-splitting library. I don't quite understand how
|
|
|
3713 COM works yet, but it looks like what's happening is
|
|
|
3714 that the ShellLink class implements both the IShellLinkA
|
|
|
3715 and IShellLinkW interfaces. To make this work at
|
|
|
3716 run-time, we have to do something like this:
|
|
|
3717
|
|
|
3718 -- define a new interface qxeIShellLink that uses
|
|
|
3719 Extbyte * instead of LPSTR or LPWSTR. (not totally
|
|
|
3720 necessary since Extbyte * == LPSTR).
|
|
|
3721
|
|
|
3722 -- define a new class qxeShellLink that implements
|
|
|
3723 qxeIShellLink. the methods on this class need to create
|
|
|
3724 a shadow ShellLink object to do all the real work, and
|
|
|
3725 call the corresponding function from either the
|
|
|
3726 IShellLinkA or IShellLinkW interfaces on this object,
|
|
|
3727 depending on whether XEUNICODE_P is defined.
|
|
|
3728
|
|
|
3729 -- with appropriate preprocessor magic, of course, we
|
|
|
3730 could make things appear transparent; but we've decided
|
|
|
3731 not to do preprocessor magic for the moment.
