    copied!<p><em>Disclaimer: This is part of the requirement of the program, so it's not meant for anything bad. Feel free to point out any misuse if you spot one. I'm a beginner in C++.</em></p> <p>Basically, I'm trying to restart <code>Outlook.exe</code> on Windows using C++.</p> <p>And this is the code I used to restart Outlook.</p> <pre><code>#include &lt;TlHelp32.h&gt; void RestartOutlook() { PROCESSENTRY32 Pc = { sizeof(PROCESSENTRY32) }; HANDLE hSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPALL, 0); MODULEENTRY32 Mo = {sizeof (MODULEENTRY32) }; if(Process32First(hSnapshot, &amp;Pc)){ do{ if(!_stricmp(Pc.szExeFile, "outlook.exe")) { DWORD pid = Pc.th32ProcessID; HANDLE hModuleSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPMODULE, pid); //kill outlook HANDLE process = OpenProcess(PROCESS_ALL_ACCESS, TRUE, pid); DWORD fdwExit = 0; GetExitCodeProcess(process, &amp;fdwExit); TerminateProcess(process, fdwExit); char * path; if (Module32First(hModuleSnapshot, &amp;Mo)) { path = Mo.szExePath; STARTUPINFO si; PROCESS_INFORMATION pi; ZeroMemory(&amp;si, sizeof(si)); si.cb = sizeof (si); CreateProcess(path, NULL, NULL, NULL, false, NORMAL_PRIORITY_CLASS, NULL, NULL, &amp;si, &amp;pi); } } }while(Process32Next(hSnapshot, &amp;Pc)); } } </code></pre> <p>The funny part is, this piece of code works perfectly fine on Windows 7. While on Windows XP (SP3), I get duplicated Outlook. The <code>GetLastError</code> gives me <code>6: ERROR_INVALID_HANDLE</code>. I am really clueless after hours of research.</p> <p>Any idea?</p> <p>Anyway, C++ is not my field. I do webs :)</p> <p>And the code above is a mixture of the following sources:</p> <blockquote> <p>1: <a href="http://www.istorya.net/forums/programming/107435-how-can-i-kill-a-process-using-c.html" rel="nofollow">http://www.istorya.net/forums/programming/107435-how-can-i-kill-a-process-using-c.html</a></p> <p>2: <a href="http://code.activestate.com/recipes/576362-list-system-process-and-process-information-on-win/" rel="nofollow">http://code.activestate.com/recipes/576362-list-system-process-and-process-information-on-win/</a></p> </blockquote> <p><em>Environment: Windows 7, Windows XP, VS2010, Outlook 2003, Outlook 2007, Outlook 2010</em></p>
