1529 When running under a debugger, every time I hit F12 (which for me

1539
|
|
|
1540 (Knowledge Base Q130667, PRB: F12 Causes Hard-Coded Breakpoint
|
|
|
1541 Exception When Debugging)
|
|
|
1542
|
|
|
1543 CAUSE
|
|
|
1544
|
|
|
1545 When the F12 key is pressed and the application in focus is being
|
|
|
1546 debugged, Windows NT calls a function similar to DebugBreak(),
|
|
|
1547 which executes a hard coded breakpoint instruction. The integrated
|
|
|
1548 debugger then traps the exception generated by this instruction.
|
|
|
1549
|
|
|
1550 This behavior is intentional and occurs with other debuggers such
|
|
|
1551 as WinDbg from the Windows 32-bit SDK.
|
|
|
1552
|
|
|
1553 RESOLUTION
|
|
|
1554
|
|
|
1555 While there is no way to disable this functionality, it doesn't
|
|
|
1556 affect the application that's being debugged other than to pause
|
|
|
1557 debugging and change focus. You can continue debugging by pressing
|
|
|
1558 the F5 key.
|
|
|
1559
|
|
|
1560 This can be annoying if you have an application that heavily uses
|
|
|
1561 the F12 key, so you may want to temporarily assign another key to
|
|
|
1562 handle the F12 key functionality in your program when debugging.
|
|
|
1563
|
|
|
1564 STATUS
|
|
|
1565
|
|
|
1566 This behavior is by design.
|
|
|
1567
|
|
|
1568
|
|
|
1569 However, elsewhere I found this:
|
|
|
1570
|
|
|
1571 UserDebuggerHotKey
|

|
1572 HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AeDebug

1576
|
|
|
1577 Description
|
|
|
1578
|
|
|
1579 Specifies the key that, when pressed, establishes a breakpoint in
|
|
|
1580 code being debugged.
|
|
|
1581
|
|
|
1582 The debugger interrupts code processing at the breakpoint so the
|
|
|
1583 programmer can examine a suspected problem.
|
|
|
1584
|
|
|
1585 The key specified in this value only sets a breakpoint. It does
|
|
|
1586 not invoke the debugger (the debugger must be running before the
|
|
|
1587 key is pressed) and it does not switch the debugger to single-step
|
|
|
1588 mode.
|
|
|
1589
|
|
|
1590 The value of this entry is a keyboard scan code. The default
|
|
|
1591 value, 0x0, represents the F12 key on a 101-key keyboard or the -
|
|
|
1592 (hyphen, VK_SUBTRACT) key on an 82-key keyboard.

2258 think. In particular, QUIT checking will query and remove

2259 events, including keyboard events, from the queue. (QUIT is
|
|
|
2260 definitely invoked from TO_INTERNAL_FORMAT().) If we do

2261 this recursively anywhere in the following code, it will
|
|

2262 mess certain things up -- in particular, the OS-provided

|
2267 triggered only every 1/4 second, why is it getting
|
|
|
2268 consistently triggered here? I saw the problem
|
|
|
2269 consistently. Answer: It appears that, currently,
|
|
|
2270 sometimes the code to pump messages is wrapped with
|
|
|
2271 begin_dont_check_for_quit() and sometimes it isn't. (####
|
|
|
2272 FIX THIS SHIT!) cmdloop.c, for example, has it, but not
|
|
|
2273 everywhere. The current games with avoiding QUIT mean that
|
|
|
2274 the 1/4-second timer consistently fires while
|
|
|
2275 dont_check_for_quit is set [which causes the quit check to
|
|
|
2276 get deferred but the flag is still on], and so the next
|
|
|
2277 time it's unset and we call QUIT is *right here*.
|
|
|
2278
|
|
|
2279 In my stderr-proc ws I majorly cleaned up the whole shit by
|
|
|
2280 just wrapping all the entry points in dont_check_for_quit.
|
|
|
2281 This fixed the remaining bugs with C-g getting interpreted
|
|
|
2282 wrong.)
|
|
|
2283
|
|
|
2284 #### We should probably wrap this whole function in
|
|
|
2285 begin_dont_check_for_quit(); but then we should set this
|
|
|
2286 back to 0 when handling a menu callback, which gets invoked
|
|
|
2287 from within this function, specifically from
|
|
|
2288 DefWindowProc(). (We already do the latter in my new

3344 Note the following in the docs:
|
|
|
3345
|
|
|
3346 Note: The IShellLink interface has an ANSI version
|
|
|
3347 (IShellLinkA) and a Unicode version (IShellLinkW). The
|
|
|
3348 version that will be used depends on whether you compile
|
|
|
3349 for ANSI or Unicode. However, Microsoft® Windows 95 and
|
|
|
3350 Microsoft® Windows 98 only support IShellLinkA.
|
|
|
3351
|
|
|
3352 We haven't yet implemented COM support in the
|
|
|
3353 Unicode-splitting library. I don't quite understand how
|
|
|
3354 COM works yet, but it looks like what's happening is
|
|
|
3355 that the ShellLink class implements both the IShellLinkA
|
|
|
3356 and IShellLinkW interfaces. To make this work at
|
|
|
3357 run-time, we have to do something like this:
|
|
|
3358
|
|
|
3359 -- define a new interface qxeIShellLink that uses
|
|
|
3360 Extbyte * instead of LPSTR or LPWSTR. (not totally
|
|
|
3361 necessary since Extbyte * == LPSTR).
|
|
|
3362
|
|
|
3363 -- define a new class qxeShellLink that implements
|
|
|
3364 qxeIShellLink. the methods on this class need to create
|
|
|
3365 a shadow ShellLink object to do all the real work, and
|
|
|
3366 call the corresponding function from either the
|
|
|
3367 IShellLinkA or IShellLinkW interfaces on this object,
|
|
|
3368 depending on whether XEUNICODE_P is defined.
|
|
|
3369
|
|
|
3370 -- with appropriate preprocessor magic, of course, we
|
|
|
3371 could make things appear transparent; but we've decided
|
|
|
3372 not to do preprocessor magic for the moment.
