    <p>The fastest way to scan for processes is via NTDLL's NtQuerySystemInformation call. It provides you with a list of names and process IDs of all processes on the system with a single call (or more in rare cases, i.e. large # of processes). You can combine NtQuerySystemInformation and use a hash to do string comparisons instead of comparing each byte.</p> <pre><code>// headers @ http://pastebin.com/HWzJYpbv NtQuerySystemInformation = (_RT_NAPI_QUERYSYSINFO)GetProcAddress(GetModuleHandleA("NTDLL.DLL"), "NtQuerySystemInformation"); // Get process information buffer do { // Allocate buffer for process info pBuffer = HeapAlloc(hHeap, HEAP_ZERO_MEMORY, cbBuffer); if (pBuffer == NULL) { // Cannot allocate enough memory for buffer (CRITICAL ERROR) return 1; } // Obtain system process snapshot Status = NtQuerySystemInformation(5, pBuffer, cbBuffer, NULL); // Allocate bigger buffer for moar data if (Status == STATUS_INFO_LENGTH_MISMATCH) { HeapFree(hHeap, 0, pBuffer); cbBuffer *= 2; // Increase the size of the buffer :-) } else if ((Status) != 0x00) { // Can't query process information (probably rootkit or anti-virus) HeapFree(hHeap, 0, pBuffer); return 1; } } while (Status == STATUS_INFO_LENGTH_MISMATCH); // Get pointer to first system process info structure pInfo = (PSYSTEM_PROCESS_INFORMATION)pBuffer; // Loop over each process for (;;) { // Get process name pszProcessName = pInfo-&gt;ImageName.Buffer; // ... do work. For a fast string compare, calculate a 32-bit hash of the string, then compare to a static hash. if(CRC32(pszProcessName) == 0xDEADBEEF /* &lt;- hash of adobe reader process name goez here */) { // Found process } // Load next entry if (pInfo-&gt;NextEntryOffset == 0) break; pInfo = (PSYSTEM_PROCESS_INFORMATION)(((PUCHAR)pInfo)+ pInfo-&gt;NextEntryOffset); } </code></pre> <p><strong>Tested on Windows 2000 - Windows 7 English editions, x64/x86 (except Win XP x64)</strong> Note: It will return all processes to 32-bit WOW64 processes on 64-bit systems.</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.

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).
