1361 * This is a special flavor of the mswindows_need_event function,

1362 * used while in event pump. Actually, there is only kind of events
|
|
|
1363 * allowed while in event pump: a timer. An attempt to fetch any
|
|
|
1364 * other event leads to a deadlock, as there's no source of user input
|
|
|
1365 * ('cause event pump mirrors windows modal loop, which is a sole
|
|
|
1366 * owner of thread message queue).
|
|
|
1367 *
|
|
|
1368 * To detect this, we use a counter of active timers, and allow
|
|
|
1369 * fetching WM_TIMER messages. Instead of trying to fetch a WM_TIMER
|
|
|
1370 * which will never come when there are no pending timers, which leads
|
|
|
1371 * to deadlock, we simply signal an error.

1372 *
|
|
|
1373 * It might be possible to combine this with mswindows_drain_windows_queue
|
|

1374 * which fetches events when not in a modal loop. It's not clear
|
|
|
1375 * whether the result would be more complex than is justified.

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

|
|
|
1571 This behavior is by design.

|

1573
|
|
|
1574 However, elsewhere I found this:

1582 Description
|
|
|
1583
|
|
|
1584 Specifies the key that, when pressed, establishes a breakpoint in
|
|
|
1585 code being debugged.
|
|
|
1586
|
|
|
1587 The debugger interrupts code processing at the breakpoint so the
|
|
|
1588 programmer can examine a suspected problem.
|
|
|
1589
|
|
|
1590 The key specified in this value only sets a breakpoint. It does
|
|
|
1591 not invoke the debugger (the debugger must be running before the
|
|
|
1592 key is pressed) and it does not switch the debugger to single-step
|
|
|
1593 mode.
|
|
|
1594
|
|
|
1595 The value of this entry is a keyboard scan code. The default
|
|
|
1596 value, 0x0, represents the F12 key on a 101-key keyboard or the -
|
|
|
1597 (hyphen, VK_SUBTRACT) key on an 82-key keyboard.

2264 events, including keyboard events, from the queue. (QUIT is
|
|
|
2265 definitely invoked from TO_INTERNAL_FORMAT().) If we do

2266 this recursively anywhere in the following code, it will
|
|

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

2289 #### We should probably wrap this whole function in
|
|
|
2290 begin_dont_check_for_quit(); but then we should set this

|
2291 back to 0 when handling a menu callback, which gets invoked
|
|
|
2292 from within this function, specifically from
|

3349 Note the following in the docs:
|
|
|
3350
|
|
|
3351 Note: The IShellLink interface has an ANSI version
|
|
|
3352 (IShellLinkA) and a Unicode version (IShellLinkW). The
|
|
|
3353 version that will be used depends on whether you compile
|
|
|
3354 for ANSI or Unicode. However, Microsoft® Windows 95 and
|
|
|
3355 Microsoft® Windows 98 only support IShellLinkA.
|
|
|
3356
|
|
|
3357 We haven't yet implemented COM support in the
|
|
|
3358 Unicode-splitting library. I don't quite understand how
|
|
|
3359 COM works yet, but it looks like what's happening is
|
|
|
3360 that the ShellLink class implements both the IShellLinkA
|
|
|
3361 and IShellLinkW interfaces. To make this work at
|
|
|
3362 run-time, we have to do something like this:
|
|
|
3363
|
|
|
3364 -- define a new interface qxeIShellLink that uses
|
|
|
3365 Extbyte * instead of LPSTR or LPWSTR. (not totally
|
|
|
3366 necessary since Extbyte * == LPSTR).
|
|
|
3367
|
|
|
3368 -- define a new class qxeShellLink that implements
|
|
|
3369 qxeIShellLink. the methods on this class need to create
|
|
|
3370 a shadow ShellLink object to do all the real work, and
|
|
|
3371 call the corresponding function from either the
|
|
|
3372 IShellLinkA or IShellLinkW interfaces on this object,
|
|
|
3373 depending on whether XEUNICODE_P is defined.
|
|
|
3374
|
|
|
3375 -- with appropriate preprocessor magic, of course, we
|
|
|
3376 could make things appear transparent; but we've decided
|
|
|
3377 not to do preprocessor magic for the moment.
