XP SP3: changes in stream "005SummaryInformation" Hi all, we are using the stream "005SummaryInformation" in our application to write comments to files. These comments are viewable in File > Properties > File Info. In the absence of documentation we just took a snapshot of different stream states that we have created with XP SP2. These snapshots were written to... 28 Jun 2008 17:48
ZwCreate file hooking and opening the file in user space to calculate the md5 sum I suspect you could do what you needed with a filesystem filter driver, no need to resort to undocumented hacks like hooking the SDT. ... 27 Jun 2008 12:09
MiniDumpWriteDump fails with error 0x8007012B (Only part of a ReadProcessMemory or WriteProcessMemory request was completed.) Hi, I call MiniDumpWriteDump in an exception filter, in a crashed process (but in another thread, not it the thread that crashed). Sometimes it fails, creating corrupt dumps (not empty, but unrecognizable by VC++ and windbg) and when this happens GetLastError() returns 0x8007012B (Only part of a ReadProcessMemor... 7 Jul 2008 10:26
ZwCreate file hooking and opening the file in user space to calculate the md5 sum Hi, I have hooked ZwCreateFile (SSDT)for some benign purpose. As i received the event at user space, i need to calculate the md5 of the created file and for this i need to open the file.

This most often happens after a long user session BUT if the user logs out the flag stays set ... 27 Jun 2008 07:00

Forcing a process to sleep Hello, I have an application that is constantly running at 100% CPU and causing everything to be sluggish. Another GUI application runs at the same time and needs to be responsive. I do not have sources for either of these applications. Now, reducing the priority of the CPU hogging process does not help much. No... 27 Jun 2008 05:59
Time since wakeup? I'm pretty sure I recently read about an API that would let me know how long it has been since a laptop woke up (i.e., how long it had been running after being in sleep or hibernate (or OFF) mode) but I can't remember it or find anything about it. Anyone? Thanks. ... 28 Jun 2008 02:29
