createprocess

Hi all, I've been struggling with the WinAPI CreateProcess for some time now. I've googled/yahoo'ed all over to find a simple explanation on how to use it and i havnt found anything close to how to use it properly. I know it takes 10 parameters in order to use so says MSDN. But im still not finding a way to use it for something simply. Any help and or suggestions on the matter is greatly appreciated. Thanx in advance!

So the "example" provided in the MSDN online documentation is not "simple" enough? or you can't get it to work? or....???

You can pass NULL, 0, and/or FALSE for all the parameters except lpApplicationName, lpStartupInfo, and lpProcessInformation. That should simplify it :) Mark

:omg: Beyond words. Why not show us what you've tried so we can see where you've gone astray?

Im having trouble with this. #include #include using namespace std; int main(i) { CreateProcess(("notpad.exe"),NULL,NULL,NULL,FALSE,0,NULL,NULL,NULL,NULL); printf("Failed because: %s", GetLastError()); return 0; }

What's this?

Should be:

printf("Failed because: %lu", GetLastError());

Is "notpad.exe" the app you want to run? Also you need to pass something to those last two parameters, especially the last one, since there's some handles returned that need to be freed.

STARTUPINFO StartupInfo;
memset(&StartupInfo, 0, sizeof(STARTUPINFO));
StartupInfo.cb = sizeof(STARTUPINFO);

PROCESS_INFORMATION ProcessInformation;

if (0 == ::CreateProcess(_T("C:\\Windows\\system32\\notepad.exe"), // LPCTSTR lpApplicationName,
                            NULL,                    // LPTSTR lpCommandLine,
                            NULL,                    // LPSECURITY_ATTRIBUTES lpProcessAttributes,
                            NULL,                    // LPSECURITY_ATTRIBUTES lpThreadAttributes,
                            FALSE,                   // BOOL bInheritHandles,
                            NORMAL_PRIORITY_CLASS,   // DWORD dwCreationFlags,
                            NULL,                    // LPVOID lpEnvironment,
                            NULL,                    // LPCTSTR lpCurrentDirectory,
                            &StartupInfo,    &n
