You can do that by queuing a user APC routine - see 'QueueUserWorkItem()' (<a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dllproc/hh/winbase/prothred_1ar1.asp" rel="ugc">http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dllproc/hh/winbase/prothred_1ar1.asp</a>) or 'QueueUserAPC()' ( == 'ZwQueueAPCThread()' in KMode). Both have an equivalent in kernel mode, though I only can remember the latter one now...

Hello Everybody:<br />
<br />
I am developing file system filter driver in Winnt.<br />
Dispatch routines are called with any thread context.<br />
I need to execute several routines in my driver in a specific user process address space, in order to access buffer/object that created in the specific<br />
user process.<br />
<br />
Does anyone know how it can be done ?<br />
<br />
Thanks<br />

Change thread context(address space)

Most development for the Microsoft platform is done utilizing the technologies supported by the.NET framework. Other development is done using Visual Basic for Applications (VBA) for programs like Access, Excel, Word and Outlook, with PowerShell for scripting, or with SQL for large databases.
