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?
