I hope it helps.

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?

char chBuffer[25]={0};
char* pchString = "Your String";
lstrcpy(chBuffer, pchString);
chBuffer[6]=0;
Now:
-----
chBuffer == "Your S" and pchString == "Your String"

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 ...

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.

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

Here's a piece of MSDN remark about PostThreadMessage():
-----------------------------------------------------------------------------
Messages sent by PostThreadMessage are not associated with a window. As a general rule, messages that are not associated with a window cannot be dispatched by the DispatchMessage function. Therefore, if the recipient thread is in a modal loop (as used by MessageBox or DialogBox), the messages will be lost. To intercept thread messages while in a modal loop, use a thread-specific hook.
My questions are:
----------------------
1) What's modal loop?
2) Why a given message will be lost in such a condition?
3) Which thread-specific hook should I use to catch such a messages?
Thanx
|
|
|
|
|
1) a modal loop means the program is currently in a state hold by a modal dialog...
2) don't know, but if they documented so, I believe we can trust them
3) don't they give more infos or example ?

OK, this is point of argument between me and this other student at university.
#include
#include <stdio.h>
#include <unistd.h>
int main()
{
int i;
i = 0;
while(i<3)
{
pid_t pid = fork();
if(pid == 0)
{
printf("Parent Value = %d\n", i);
}
else
{
printf("Child_%d Value = %d\n",pid, i);
}
i++;
}
}
</unistd.h></stdio.h>
What exactly is happening here?
The argument being the starting location of the newly created process.
