[Windows SDK] Pipe status

Hello world!

How to detect if a windows named pipe is FULL Confused | :confused:

I use a overlapped structure and the GetOverlappedResult function (for asynchronous I/O).
When my named pipe is full I want to wait free space to continue writing data (like a FIFO).
But I don't know how to detect if my pipe is full?

Thanks for any help, advices, etc...

You can't.

One of the ideas of overlapped I/O is so that you don't
have to wait. Overlapped I/O is also FIFO already.

If you want to wait, don't use overlapped I/O.

Thanks for your reply...

My problem is that I've a first process that writes data (raw image) to a pipe and a second process which connects to this pipe and reads data from the pipe.
I want to use overlapped structure to let the first process write the next data without waiting until the second process read the old data.

It's important for the first process to know when the pipe is full because at this time It can skip images.

If you have any suggestions to do that...

Thanks in advance. Smile | :)

Throttling data stream rate can be complex. You could establish a
constant rate or use an adjustable/variable rate based on comm
conditions, which are continuously monitored.

You'll maybe want to somehow keep track of how many overlapped operations
are pending. If this value keeps increasing, then you need to slow
the send rate until the amount of pending ops stays constant.

System time infor mations

Hi all,

I'm going to learn a new subject on C++. Working with Windows API. Since I work with Java there is no API used, but I feel it is better to work a little with APIs.

Here is my attempt for that.

I want to read the system time zones and display on the console. Basically in two columns, City and the Time offset. From where I should start work. Can you guys give some clues. Following week I'm free because of Christmas, so I can do some work on it.

Thanks

I appreciate your help all the time...

Actually I'm looking to get the timezone details from the system. I mean if you check the time zone drop-down menu you can see a large number of timezones list. What I want to do is read all of them and print on a console. Smile | :)

I appreciate your help all the time...

A time zone is simply the number of hours a particular area is from UTC. So you could get fairly close with something like:

for (int x = -12; x < 15; x++)
{
    if (x < 0)
        printf("UTC%d\n", x);
    else if (x > 0)
        printf("UTC+%d\n", x);
    else
        printf("UTC\n");
}

You can add this to a list of some sort, along with some familiar city located within each zone.

"Normal is getting dressed in clothes that you buy for work and driving through traffic in a car that you are still paying for, in order to get to the job you need to pay for the clothes and the car and the house you leave vacant all day so you can afford to live in it." - Ellen Goodman

Thanks for your code.

I think there is one thing, which I can't do. The list of time zone names. Only I can get the systems' time zone informations. Is that right. When I go through the MSDN, that what I got.

I appreciate your help all the time...

Other than the convention that I provided, I do not know of a standard 'name' for time zones.

Ok, say I want to do this. User gives the time offset, say -6:30 as an example. Now I want to find the appropriate time zone name. From where I should find it?

I appreciate your help all the time...

When I move the dialog box I just want to paint the border. This is the deafult behaviour in Java/Swing. It avoids a lot of flickering and refresh problem.
Is there any easy way to achive this in wonodws?

Windows is in a constant state of swapping data to/from disk.
