CreateProcess - Unhandled exception??

[pilgie]

Hi all,

When running the following I recieve an unhandled exception error - I am running against the Unicode character set, could this be causing the error?

SECURITY_ATTRIBUTES sa = { sizeof(SECURITY_ATTRIBUTES) };
sa.bInheritHandle = TRUE;
sa.lpSecurityDescriptor = NULL;

HANDLE hStdoutRd, hStdoutWr, hStdinRd, hStdinWr;

CreatePipe (&hStdoutRd, &hStdoutWr, &sa, 0);
SetHandleInformation(hStdoutRd, HANDLE_FLAG_INHERIT, 0);
CreatePipe (&hStdinRd, &hStdinWr, &sa, 0);
SetHandleInformation(hStdinWr, HANDLE_FLAG_INHERIT, 0);

STARTUPINFO si = { sizeof(STARTUPINFO) };
PROCESS_INFORMATION pi;
si.dwFlags = STARTF_USESTDHANDLES;
si.hStdOutput = hStdoutWr;
si.hStdInput = hStdinRd;

if(!CreateProcess (NULL, (LPWSTR)"c:\php\php-cgi.exe", NULL, NULL, TRUE,CREATE_UNICODE_ENVIRONMENT | NORMAL_PRIORITY_CLASS, NULL, NULL, &si, &pi))
{
printf( "CreateProcess failed (%d)\n", GetLastError() );
}
I recieve an unhandled exception:

Unhandled exception at 0x00479986 in WebserverTest.exe: 0xC0000005: Access violation reading location 0x00000274.

Any ideas as to what this could be?

Help appreciated - cheers people!

Well simply casting the string to make the compiler shut up about something isn't the way to go.

1. If you're using UNICODE, then use the TEXT macros (and other things) which are designed to smooth the portability between ASCII and UNICODE.
2. You forgot to double up all your \\ in the pathname.
3. Please use [code][/code] tags when posting code.

Eg.

if ( !CreateProcess (NULL, TEXT("c:\\php\\php-cgi.exe"), NULL, NULL, TRUE,CREATE_UNICODE_ENVIRONMENT | NORMAL_PRIORITY_CLASS, NULL, NULL, &si, &pi))
