How to get the name of an active window?

Question

I've confronted with problem of getting active window's name.

When I use this code:

HWND currentWindowHWND = GetForegroundWindow();
char title[100];
GetWindowTextA(currentWindowHWND, title, 100);

I get something like: "How to get active window's name? - Stack Overflow - Google Chrome".

But I want to get "Google Chrome", which WINAPI function should I use?

Answer 1

in a c code use the following winapi functions:

DWORD WINAPI GetModuleFileName(
  _In_opt_  HMODULE hModule,
  _Out_     LPTSTR lpFilename,
  _In_      DWORD nSize
);

or

DWORD WINAPI GetModuleBaseName(
  _In_      HANDLE hProcess,
  _In_opt_  HMODULE hModule,
  _Out_     LPTSTR lpBaseName,
  _In_      DWORD nSize
);

How to get the process name in C++

In c#:

Int32 pid = win32.GetWindowProcessID(hwnd);
Process p = Process.GetProcessById(pid);
string appName = p.ProcessName;

You should get the process name and not the window's title.
