    <p>I have a class (NamedPipeManager) which has a thread (PipeThread) that waits for a NamedPipe connection using (ConnectNamedPipe) and then reads (ReadFile) - these are blocking calls (not-overlapped) - however there comes a point when I want to unblock them - for example when the calling class tries to stop the NamedPipeManager...</p> <p>How can I interupt it? Using Thread.abort? Thread.interrupt? Is there a proper way to handle this? Refer to the code below which illustrates my current situation</p> <pre><code>main() { NamedPipeManager np = new NamedPipeManager(); ... do stuff ... ... do stuff ... np.Stop(); // at this point I want to stop waiting on a connection } class NamedPipeManager { private Thread PipeThread; public NamedPipeManager { PipeThread = new Thread(new ThreadStart(ManagePipes)); PipeThread.IsBackground = true; PipeThread.Name = "NamedPipe Manager"; PipeThread.Start(); } private void ManagePipes() { handle = CreateNamedPipe(..., PIPE_WAIT, ...); ConnectNamedPipe(handle, null); // this is the BLOCKING call waiting for client connection ReadFile(....); // this is the BLOCKING call to readfile after a connection has been established } public void Stop() { /// This is where I need to do my magic /// But somehow I need to stop PipeThread PipeThread.abort(); //?? my gut tells me this is bad } }; </code></pre> <p>So, in function Stop() - how would I gracefully unblock the call to ConnectNamedPipe(...) or ReadFile(...)?</p> <p>Any help would be appreciated. Thanks,</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
