January 31, 2006Jan 31, 200601/31/06On FAT drives, the directory that stores files in the Recycle Bin is called C:\RECYCLED, but on NTFS drives, its name is C:\RECYCLER. Why the name change?
The FAT and NTFS Recycle Bins have different internal structure because NTFS has this thing called “security”
January 31, 2006Jan 31, 200601/31/06If you dare, spend eleven minutes of your life watching the most painfully compelling mockumentary on the lives of two basement fantasy role playing gamers. (via Chris Williams.)
January 30, 2006Jan 30, 200601/30/06Of course we don’t find this out until somebody tries. (Google cache for a limited time only.)
January 30, 2006Jan 30, 200601/30/06If you take a program and corrupt the header, or just take a large-ish file that isn’t a program at all and give it a “.exe” extension, then try to run it (Warning: Save your work first!), you will typically get the error “Program too big to fit in memory”.
January 27, 2006Jan 27, 200601/27/06The MsgWaitForMultipleObjects and MsgWaitForMultipleObjectsEx functions allow you to specify whether you want to want for any or all of the handles (either by passing bWaitAll = TRUE or by passing dwFlags = MWMO_WAITALL, accordingly). But you never want to wait for all handles.
January 26, 2006Jan 26, 200601/26/06Stephen Tolouse (known around Microsoft as “stepto”, pronounced “step-toe”) from the Microsoft Security Response Center reminisces about Windows 95 RTM.
Stephen mentions that “the build numbers were artificially inflated to reach 950”. There’s actually a technical reason for this inflation, which I intend to write about when I have the time to give the topic the treatment it deserves.
January 26, 2006Jan 26, 200601/26/06We can use the MsgWaitForMultipleObjects function
(or its superset MsgWaitForMultipleObjectsEx)
to carry out a non-polling “sleep while processing messages”.
#define MSGF_SLEEPMSG 0x5300
BOOL SleepMsg(DWORD dwTimeout)
{
DWORD dwStart = GetTickCount();
DWORD dwElapsed;
while ((dwElapsed = GetTickCount() – dwStart) < dwTimeout) {
DWORD dwStatus = MsgWaitForMultipleObjectsEx(0,
January 25, 2006Jan 25, 200601/25/06Vancouver technologist Darren Barefoot was invited to Redmond by the MSN Search team but was stopped by Immigration and denied entry.
Ultimately, the customs agents concluded that because Microsoft was covering my flight and accommodation, I was being compensated for consulting activities.
January 25, 2006Jan 25, 200601/25/06There is no WaitMessageTimeout function,
but you can create your own with the assistance of
the MsgWaitForMultipleObjects function.
BOOL WaitMessageTimeout(DWORD dwTimeout)
{
return MsgWaitForMultipleObjects(
0, NULL, FALSE, dwTimeout, QS_ALLINPUT)
== WAIT_TIMEOUT;
}
To wait for a message with timeout, we use
the MsgWaitForMultipleObjects
in a vacuous sense:
You pass it a list of objects you want to wait for,
