Answer 1

TCHAR buffer[128];
::GetClassName(hwnd, buffer, sizeof(buffer)/sizeof(TCHAR));

Answer 2

void IterateWindows(long hWnd)
{
long childhWnd,looper;
childhWnd = (long)GetNextWindow((HWND)hWnd,GW_CHILD);
GetClassName( (HWND)childhWnd, g_classNameBuf, sizeof(g_classNameBuf) );
while ( strcmp(g_classNameBuf, "Button") )
{
// IterateWindows(childhWnd);
childhWnd = (long)GetNextWindow((HWND)childhWnd ,GW_HWNDNEXT);
GetClassName( (HWND)childhWnd, g_classNameBuf, sizeof(g_classNameBuf) );
}

Answer 3

void IterateWindows(long hWnd)
{
long childhWnd,looper;
childhWnd = (long)GetNextWindow((HWND)hWnd,GW_CHILD);
GetClassName( (HWND)childhWnd, g_classNameBuf, sizeof(g_classNameBuf) );
while ( strcmp(g_classNameBuf, "Button") )
{
// IterateWindows(childhWnd);
childhWnd = (long)GetNextWindow((HWND)childhWnd ,GW_HWNDNEXT);
GetClassName( (HWND)childhWnd, g_classNameBuf, sizeof(g_classNameBuf) );
}
