Thread: Hung up on GetWindowText

I can't figure this one out. I get all the other module information as expected, but I can't get GetWindowText to give me the window title of each process. The code below just spits out "Notification Area" repeatedly. I tried using aProcesses[i] instead and got a bunch of the wrong window titles. I don't get it. I'm also curious how to determine the user running each process. I specifically want to know which ones are SYSTEM processes in order to exclude them from the list.

Code:

int ListProcesses(HWND hProcessList) {
    HANDLE hProcess;
    DWORD aProcesses[1024], cbNeeded, cProcesses;
    unsigned int i;
    char szProcessName[500];
    char szProcessPath[500];
    char szProcessID[20];
    char szProcessSize[20];
    char szProcessTitle[1024];
    PROCESS_MEMORY_COUNTERS szProcessMemory;
    SendMessage(hProcessList, LVM_DELETEALLITEMS, 0, 0);
    if ( !EnumProcesses( aProcesses, sizeof(aProcesses), &cbNeeded ) )
        return 1;

    cProcesses = cbNeeded / 4;

    for ( i = 0; i < cProcesses; i++ ) {
        if( aProcesses[i] != 0 ) hProcess = OpenProcess( PROCESS_QUERY_INFORMATION|PROCESS_VM_READ, FALSE, aProcesses[i] );
        if (NULL != hProcess )
        {
            GetModuleBaseName( hProcess, NULL, szProcessName, 500 );
            GetModuleFileNameEx( hProcess, NULL, szProcessPath, 500 );
            memset(&szProcessMemory,0,sizeof(PROCESS_MEMORY_COUNTERS));
            szProcessMemory.cb = sizeof(PROCESS_MEMORY_COUNTERS);
            GetProcessMemoryInfo(hProcess, &szProcessMemory, sizeof(PROCESS_MEMORY_COUNTERS));
            sprintf(szProcessSize, "&#37;.2f", (float)szProcessMemory.WorkingSetSize / 1024 / 1024);
            szProcessTitle[0] = '\0';
            GetWindowText(hProcess, szProcessTitle, sizeof(szProcessTitle));
            sprintf(szProcessID, "%u", aProcesses[i]);
            ListViewAddRow(hProcessList, 5, szProcessName, szProcessTitle, szProcessID, szProcessSize, szProcessPath);
        }
        CloseHandle( hProcess );
    }
	return 0;
