ShellExecute and waiting the execute file finish

I have the following code

HANDLE hShell;
hShell = ShellExecute(NULL, "open", "test.exe", "parameter1 parameter2", "C:\\", SW_SHOWDEFAULT);
CloseHandle(hShell);
MessageBox(NULL, "text.exe finished", "myProg", MB_OK);

But I would like the message "text.exe finished" display after test.exe has been finished.
Please help me....

You cannot do that with 'ShellExecute()' - use e.g.

DWORD ExecuteAndWaitForCompletion ( LPSTR pszCmd)
{
STARTUPINFO si;
PROCESS_INFORMATION pi;

BOOL bRes;

DWORD dwCode = 0;

MSG msg;

ZeroMemory ( &si, sizeof ( STARTUPINFO));

si.cb = sizeof ( STARTUPINFO);
si.dwFlags = STARTF_USESHOWWINDOW;
si.wShowWindow = SW_SHOWNORMAL;

bRes = CreateProcess ( NULL,
pszCmd,
NULL,
NULL,
TRUE,
NORMAL_PRIORITY_CLASS,
NULL,
NULL,
&si,
&pi
);

while ( WAIT_OBJECT_0 != MsgWaitForMultipleObjects ( 1,
&pi.hProcess,
FALSE,
INFINITE,
QS_ALLINPUT
)
)
{
while ( PeekMessage ( &msg, NULL, 0, 0, PM_REMOVE))
{
DispatchMessage ( &msg);
}
}

GetExitCodeProcess ( pi.hProcess, &dwCode);

CloseHandle ( pi.hProcess);
CloseHandle ( pi.hThread);

return ( dwCode);
}

and call it like

ExecuteAndWaitForCompletion ( "test.exe parameter1 parameter2",);

Um, and a lil' correction - the call above should have read

ExecuteAndWaitForCompletion ( "test.exe parameter1 parameter2");

Thank you so much....
one small question...
I used to use std::string,
what different between std::string and LPSTR?
Thanks...

>>what different between std::string and LPSTR?

'LPSTR' is a plain 'C' style string. So, you could just use

std::string str("test");
LPSTR pstr = str.c_str();
