    <p>I have followed the example <a href="http://msdn.microsoft.com/en-us/library/ms682499(VS.85).aspx" rel="nofollow">here</a> for reading from a pipe, but ReadFile fails and GetLastError() shows me that the pipe is broken.<br> I have created and used (successfully) a pipe earlier in the program, but I closed all the handles and used entirely new variables for the new pipe just to be sure.<br> Any ideas why this doesn't work?</p> <pre><code>HANDLE g_hChildStd_OUT_Rd2 = NULL; HANDLE g_hChildStd_OUT_Wr2 = NULL; SECURITY_ATTRIBUTES saAttr2; STARTUPINFO si2; PROCESS_INFORMATION pi2; ZeroMemory( &amp;si2, sizeof(si2) ); si2.cb = sizeof(si2); ZeroMemory( &amp;pi2, sizeof(pi2) ); //create pipe saAttr2.nLength = sizeof(SECURITY_ATTRIBUTES); saAttr2.bInheritHandle = TRUE; saAttr2.lpSecurityDescriptor = NULL; CreatePipe(&amp;g_hChildStd_OUT_Rd2, &amp;g_hChildStd_OUT_Wr2, &amp;saAttr2, 0); //create child process bSuccess = FALSE; memset(szCmdLine, 0, MAX_PATH); sprintf(szCmdLine, "ffmpeg.exe -i output.mp3"); ZeroMemory( &amp;pi2, sizeof(PROCESS_INFORMATION) ); ZeroMemory( &amp;si2, sizeof(STARTUPINFO) ); si2.cb = sizeof(STARTUPINFO); si2.hStdOutput = g_hChildStd_OUT_Wr2; si2.dwFlags |= STARTF_USESTDHANDLES; CreateProcess(NULL, szCmdLine, NULL, NULL, TRUE, 0, NULL, NULL, &amp;si2, &amp;pi2); //read from pipe CloseHandle(g_hChildStd_OUT_Wr2); memset(chBuf, 0, BUFSIZE); for (;;) { bSuccess = ReadFile( g_hChildStd_OUT_Rd2, chBuf, BUFSIZE, &amp;dwRead, NULL); [bSuccess is 0 and GetLastError() returns error 109] ........ </code></pre>

    1. COplease post minimal but full source code so we can use our compilers to help find the problem. full = we can compile and run it. minimal = there is only enough code to reproduce your problem

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
