Cast from hwnd

I want to loop trough all the windows running and get their hwnd and convert it to an int. Here is the function I have that attempts to do this (very similar to code i have previously posted):

Code:

---

int getProcesses(HWND hwnd) {

        HMODULE hModule;
        char szProcessName[MAX_PATH] = {0};
        DWORD dwProcesses[1024], cbNeeded, cProcesses;
        unsigned int i;
        char PIDbuf[128];

        if (!EnumProcesses(dwProcesses, sizeof(dwProcesses), &cbNeeded))
                return -1;
        cProcesses = cbNeeded / sizeof(DWORD);
        for (i = 0; i < cProcesses; i++)
                if(dwProcesses[i] != 0)
                {
                        HANDLE hProcess = OpenProcess(PROCESS_QUERY_INFORMATION |
                                PROCESS_VM_READ, FALSE, dwProcesses[i]);
                        if (NULL != hProcess)
                        {
                                strcpy(szProcessName, "System");
                                if (EnumProcessModules(hProcess, &hModule, sizeof(hModule),
                                        &cbNeeded))
                                {
                                        GetModuleBaseName(hProcess, hModule, szProcessName,
                                                sizeof(szProcessName)/sizeof(CHAR));
                                }
                        sprintf(PIDbuf, "%d : %s", (int)hProcess, szProcessName);
                        SendDlgItemMessage(hwnd, 1000, LB_ADDSTRING, 0, (LPARAM)PIDbuf);
                        }
                        CloseHandle(hProcess);
                }
        return cProcesses;
}

The problem is that all the hwnds are the same (1952) and using hModule doesn't work either. I am pretty sure that hProcess is the hwnd. All the process names work fine and the ListView works.

Code:

---

#include <windows.h>
#include <stdio.h>
#include <tchar.h>
#include <psapi.h>
void PrintProcessNameAndID( DWORD processID )
{
    TCHAR szProcessName[MAX_PATH] = TEXT("<unknown>");
    // Get a handle to the process.
    HANDLE hProcess = OpenProcess( PROCESS_QUERY_INFORMATION |
                                  PROCESS_VM_READ,
                                  FALSE, processID );
    // Get the process name.
    if (NULL != hProcess )
    {
        HMODULE hMod;
        DWORD cbNeeded;
        if ( EnumProcessModules( hProcess, &hMod, sizeof(hMod),
            &cbNeeded) )
        {
            GetModuleBaseName( hProcess, hMod, szProcessName,
                              sizeof(szProcessName)/sizeof(TCHAR) );
        }
    }
    // Print the process name and identifier.
    _tprintf( TEXT("%s  (PID: %u)\n"), szProcessName, processID );
    CloseHandle( hProcess );
}
void main( )
{
    // Get the list of process identifiers.
    DWORD aProcesses[1024], cbNeeded, cProcesses;
    unsigned int i;
    if ( !EnumProcesses( aProcesses, sizeof(aProcesses), &cbNeeded ) )
        return;
    // Calculate how many process identifiers were returned.
    cProcesses = cbNeeded / sizeof(DWORD);
    // Print the name and process identifier for each process.
    for ( i = 0; i < cProcesses; i++ )
        if( aProcesses[i] != 0 )
            PrintProcessNameAndID( aProcesses[i] );
}

Sorry I want to print out the Window handle, not the Process ID, Spy and Spy++ both do this, printing the window handle (hwnd) in hex.

abachler, void main? What's the reason for void main?
