C/C++ :: Get Window Title Text

I don't know how to get window title text of same process without setting a foreground window.

My code:

Using it, I get window handle.

struct handle_data {
unsigned long process_id;
HWND best_handle;
};
BOOL is_main_window(HWND handle) {
return GetWindow(handle, GW_OWNER) == (HWND)0 && IsWindowVisible(handle);

[Code] ....

This part doesn't work unless I use it with GetForegroundWindow(). But before using it, I have to set it. Is there any way to get window name without setting a foreground window?

unsigned long id = GetCurrentProcessId();
//HANDLE h = GetCurrentProcess();
HWND wind = find_main_window(id);
char window_title[256];
GetWindowText(wind, window_title, 256);
std::string txtt(window_title);
