How and where do you figure out that you have new data?
Dhiraj kumar Saini wrote: ecord ofvector should be up updated with the new data
If you know how and where you have new data, it shouldn't be a problem to add it to a vector... or is it............?
Somethings seem HARD to do, until we know how to do them.

You may use Microsoft Date and Time Picker control.

Hi Guys,
I have a number say 4-12 process that will operate as a set. When some new information arrives in one it occationally needs to do something in tandem with another process as quickly as possible. So, I have a thread in each process just waiting for an event to be flagged. When it is, it can check the database for the actual work.
What I have right now is a 50ms loop. This create a lot of CPU overhead from the database to be hit every 50 ms, so I'm looking for a way for two process to communicate.
Initially I thought of using a Mutex so it'll sit there waiting to aquire it, and when released the thread will immediatly check the database, but ownership becomes a problem. It's almost as if I need the opposite of a Mutex. Something that is always locked until it's unlocked.
Does anyone have thoughts on how I might get my processes to sleep until something is flagged? Thoughts?

You can use WaitForSingleObject and wait for particular event till it is set.
See documentation for details WaitForSingleObject[^].
Does it help?

I know you are using MFC. So,
CString str = _T("Bangalore");
AfxMessageBox(str.Left(6));

Hi masters!
------------
I can catch keyboard strokes using a system-wide keyboard hook (every one can  ) ...
But I can only get WM_KEYDOWN and WM_KEYUP in this way ...
What if a user is writing for example in Arabic or something? How can I understand which character she/he
is exactly typing and in which case (upper or lower)?
I'm working on a simple project, single thread, with no window to show to user ...

Ya.. it says _WIN32_WINNT>=0X500 .. I put it in projectsettings->preprocessor definitions.. Its still not working. Can I know anywhere else it has to be included.
|
|
|
|

Just try adding
#define _WIN32_WINNT 0x0500
in header file. (may be you can add it in stdafx.h)

All the forums say same thing.
make sure you define that macro before you include sddl.h
