PPROCESS_INFORMATION pi;
if (!CreateProcess(app_s, 0, 0, 0, 0, 0, 0, 0, 0, &pi))
    throw build_error();
WaitForSingleObject(pi.hProcess, INFINITE);
CloseHandle(pi.hProcess);
CloseHandle(pi.hThread);

Das geht aber net, denn :

Error 4 error C2664: 'CreateProcessW' : cannot convert parameter 10 from 'PPROCESS_INFORMATION *' to 'LPPROCESS_INFORMATION'

Hab schon in der Doku geschaut. Dort wirds so gemacht...

Edit: Hab mich vertippt - es muss PROCESS_INFORMATION heißen und nicht PPROCESS_INFORMATION...

Das Problem ist jetzt, dass es nie funzt. Vielleicht muss ich mal das Programm im 2. Parameter übergeben?

Und das Beispiel ist:

LPTSTR szCmdline[] = _tcsdup(
    TEXT("\"C:\\Program Files\\MyApp\" -L -S"));
CreateProcess(NULL, szCmdline, ...)

Creating Processes
The CreateProcess function creates a new process, which runs independently of the creating process. However, for simplicity, the relationship is referred to as a parent-child relationship.

The following code demonstrates how to create a process.

#include <windows.h>
#include <stdio.h>
#include <tchar.h>

void _tmain( int argc, TCHAR *argv[] )
{
STARTUPINFO si;
PROCESS_INFORMATION pi;

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

if( argc != 2 )
{
printf("Usage: %s [cmdline]\n", argv[0]);
return;
}

// Start the child process.
if( !CreateProcess( NULL, // No module name (use command line)
argv[1], // 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
)
{
printf( "CreateProcess failed (%d)\n", GetLastError() );
return;
}

// Wait until child process exits.
WaitForSingleObject( pi.hProcess, INFINITE );

// Close process and thread handles.
CloseHandle( pi.hProcess );
CloseHandle( pi.hThread );
}

If CreateProcess succeeds, it returns a PROCESS_INFORMATION structure containing handles and identifiers for the new process and its primary thread. The thread and process handles are created with full access rights, although access can be restricted if you specify security descriptors. When you no longer need these handles, close them by using the CloseHandle function.

You can also create a process using the CreateProcessAsUser or CreateProcessWithLogonW function. This allows you to specify the security context of the user account in which the process will execute.

Bist du damit zufrieden?

Wenn PPROCESS_INFORMATION eine Struktur ist, dann sind in der Windows API meistens sofort PPPROCESS_INFORMATION definiert als Zeiger auf PROCESS_INFORMATION.

Dein Code ist also falsch, weil Du keinen Zeiger rauchst sondern eine ganze Struktur.
