system("kill.exe");

using system(), such as WinExec() is deprecated...

then him can use... CreateProcess(NULL, "C:\\Program Files\\MyApp", ...)

STARTUPINFO si;
PROCESS_INFORMATION pi;

ZeroMemory( &si, sizeof(si) );
si.cb = sizeof(si);
ZeroMemory( &pi, sizeof(pi) );

// Start the child process.
if( !CreateProcess( NULL, // No module name (use command line).
"MyApp.exe", // Command line.
NULL, // Process handle not inheritable.
NULL, // Thread handle not inheritable.
FALSE, // Set handle inheritance to FALSE.
0, // No creation flags.
NULL, // Use parent's environment block.
NULL, // Use parent's starting directory.
&si, // Pointer to STARTUPINFO structure.
&pi ) // Pointer to PROCESS_INFORMATION structure.
)

::ShellExecute() is the function for you.

you could take a look at the MSDN[^] to see how it works

ShellExecute Api cannot be executed in Console Mode, you have to use system() function

2 possibilities :
1- you didn't read the link on the MSDN i gave you describing how ShellExecute() works
2- you didn't see you had to #include <shellapi.h>

yeah, i've seen your previous post.

actually, it depends if he has to execute his program in pure DOS mode, or if it will run under command windows in Win2000, XP, etc, where DOS don't exist anymore, and is emulated... it would work in the later cases...
