    <p><strong>Service:</strong> Creates std out,err,in named pipes. Attaches them to a process that it creates.</p> <pre><code>HANDLE hStdOut = CreateNamedPipe(szStdOutPipeName, PIPE_ACCESS_DUPLEX, PIPE_TYPE_BYTE, 1, 100, 100, 15000, pSa); yStartupInfo.hStdOutput = hStdOut; CreateProcessAsUserW( ..., yStartupInfo, ... ); </code></pre> <p>This part works. The created process's output is being redirected into the pipes.</p> <p><strong>Client:</strong> Connection to named pipe, Successful. Check if there are bytes to read with a peek (at this point bytes are pushed into the pipe!). Then read the bytes from the pipe.</p> <pre><code>hStdOutPide = CreateFileW(szPipeNameStdOut, GENERIC_READ|GENERIC_WRITE, FILE_SHARE_READ|FILE_SHARE_WRITE, NULL, OPEN_EXISTING, 0, NULL ); PeekNamedPipe(hStdOutPide, szBuffer, kunBufferSize, &amp;ulBytesRead, &amp;ulBytesAvailable, &amp;ulRemainingBytes); if( ulBytesAvailable &gt; 0) ReadFile(hStdOutPide, szBuffer, 1000, &amp;ulBytesRead, NULL) </code></pre> <p>I have removed the surrounding code that makes sure the handles are valid and the process is running and so on.</p> <p>The Peek reveals that <code>ulRemainingBytes</code> is <strong>ALWAYS</strong> <code>0</code>. Does anyone see where my error could be? I have been trying to get this to work for some time and don't know what the proper flags for anything is anymore. Please ask if you need more information!</p> <p>Security Attributes in the CreateNamesPipe are generated from a method. It is used in many other places in the code so I do not believe the problem to be there.</p> <p>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.
