Actually i am using push_back function to insert records in the form of a structure.
Now when i click a button for some selected record i have new data. I want to store this new data so that the previous record gets updated.

Thanks

do you have an ID or something unique identifying your record ?
if so, you could have used a map (I don't know exactly what you're doing BTW), which does this automatically.

so you can pop the previous data from the vector before pushing the new data in...
pop_back - Deletes the element at the end of the vector.
push_back - Add an element to the end of the vector.

Somethings seem HARD to do, until we know how to do them.

How and where do you figure out that you have 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............?

Which interprocess communication mechanism should I use?

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?

Re: Which interprocess communication mechanism should I use?

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 Laugh | :laugh:

) ...
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 ...

I am using this for setting full access permissions to a directory while its creation. Earlier you have sent me a sample code for setting full access permissions. But it is not working in my machine. Can I have any sample code for setting full access permission for a folder.
