1538
|
|
|
1539 (Knowledge Base Q130667, PRB: F12 Causes Hard-Coded Breakpoint
|
|
|
1540 Exception When Debugging)
|
|
|
1541
|
|
|
1542 CAUSE
|
|
|
1543
|
|
|
1544 When the F12 key is pressed and the application in focus is being
|
|
|
1545 debugged, Windows NT calls a function similar to DebugBreak(),
|
|
|
1546 which executes a hard coded breakpoint instruction. The integrated
|
|
|
1547 debugger then traps the exception generated by this instruction.
|
|
|
1548
|
|
|
1549 This behavior is intentional and occurs with other debuggers such
|
|
|
1550 as WinDbg from the Windows 32-bit SDK.
|
|
|
1551
|
|
|
1552 RESOLUTION
|
|
|
1553
|
|
|
1554 While there is no way to disable this functionality, it doesn't
|
|
|
1555 affect the application that's being debugged other than to pause
|
|
|
1556 debugging and change focus. You can continue debugging by pressing
|
|
|
1557 the F5 key.
|
|
|
1558
|
|
|
1559 This can be annoying if you have an application that heavily uses
|
|
|
1560 the F12 key, so you may want to temporarily assign another key to
|
|
|
1561 handle the F12 key functionality in your program when debugging.
|
|
|
1562
|
|
|
1563 STATUS
|
|
|
1564
|
|
|
1565 This behavior is by design.
|
|
|
1566
|
|
|
1567
|
|
|
1568 However, elsewhere I found this:
|
|
|
1569
|
|
|
1570 UserDebuggerHotKey

1575
|
|
|
1576 Description
|
|
|
1577
|
|
|
1578 Specifies the key that, when pressed, establishes a breakpoint in
|
|
|
1579 code being debugged.
|
|
|
1580
|
|
|
1581 The debugger interrupts code processing at the breakpoint so the
|
|
|
1582 programmer can examine a suspected problem.
|
|
|
1583
|
|
|
1584 The key specified in this value only sets a breakpoint. It does
|
|
|
1585 not invoke the debugger (the debugger must be running before the
|
|
|
1586 key is pressed) and it does not switch the debugger to single-step
|
|
|
1587 mode.
|
|
|
1588
|
|
|
1589 The value of this entry is a keyboard scan code. The default
|
|
|
1590 value, 0x0, represents the F12 key on a 101-key keyboard or the -
|
|
|
1591 (hyphen, VK_SUBTRACT) key on an 82-key keyboard.

2257 think. In particular, QUIT checking will query and remove

2258 events, including keyboard events, from the queue. (QUIT is
|
|
|
2259 definitely invoked from TO_INTERNAL_FORMAT().) If we do
|
|

2260 this recursively anywhere in the following code, it will
|
|
|
2261 mess certain things up -- in particular, the OS-provided

|

|
2266 triggered only every 1/4 second, why is it getting
|
|
|
2267 consistently triggered here? I saw the problem
|
|
|
2268 consistently. Answer: It appears that, currently,
|
|
|
2269 sometimes the code to pump messages is wrapped with
|
|
|
2270 begin_dont_check_for_quit() and sometimes it isn't. (####
|
|
|
2271 FIX THIS SHIT!) cmdloop.c, for example, has it, but not
|
|
|
2272 everywhere. The current games with avoiding QUIT mean that
|
|
|
2273 the 1/4-second timer consistently fires while
|
|
|
2274 dont_check_for_quit is set [which causes the quit check to
|
|
|
2275 get deferred but the flag is still on], and so the next
|
|
|
2276 time it's unset and we call QUIT is *right here*.
|
|
|
2277
|
|
|
2278 In my stderr-proc ws I majorly cleaned up the whole shit by
|
|
|
2279 just wrapping all the entry points in dont_check_for_quit.
|
|
|
2280 This fixed the remaining bugs with C-g getting interpreted
|
|
|
2281 wrong.)
|
|
|
2282
|
|
|
2283 #### We should probably wrap this whole function in
|
|
|
2284 begin_dont_check_for_quit(); but then we should set this
|
|
|
2285 back to 0 when handling a menu callback, which gets invoked
|
|
|
2286 from within this function, specifically from
|
|
|
2287 DefWindowProc(). (We already do the latter in my new

3343 Note the following in the docs:
|
|
|
3344
|
|
|
3345 Note: The IShellLink interface has an ANSI version
|
|
|
3346 (IShellLinkA) and a Unicode version (IShellLinkW). The
|
|
|
3347 version that will be used depends on whether you compile
|
|
|
3348 for ANSI or Unicode. However, Microsoft® Windows 95 and
|
|
|
3349 Microsoft® Windows 98 only support IShellLinkA.
|
|
|
3350
|
|
|
3351 We haven't yet implemented COM support in the
|
|
|
3352 Unicode-splitting library. I don't quite understand how
|
|
|
3353 COM works yet, but it looks like what's happening is
|
|
|
3354 that the ShellLink class implements both the IShellLinkA
|
|
|
3355 and IShellLinkW interfaces. To make this work at
|
|
|
3356 run-time, we have to do something like this:
|
|
|
3357
|
|
|
3358 -- define a new interface qxeIShellLink that uses
|
|
|
3359 Extbyte * instead of LPSTR or LPWSTR. (not totally
|
|
|
3360 necessary since Extbyte * == LPSTR).
|
|
|
3361
|
|
|
3362 -- define a new class qxeShellLink that implements
|
|
|
3363 qxeIShellLink. the methods on this class need to create
|
|
|
3364 a shadow ShellLink object to do all the real work, and
|
|
|
3365 call the corresponding function from either the
|
|
|
3366 IShellLinkA or IShellLinkW interfaces on this object,
|
|
|
3367 depending on whether XEUNICODE_P is defined.
|
|
|
3368
|
|
|
3369 -- with appropriate preprocessor magic, of course, we
|
|
|
3370 could make things appear transparent; but we've decided
|
|
|
3371 not to do preprocessor magic for the moment.
