Re: Maximized n minimized other application

Here is one solution

Code to find hwnd from process ID:

struct ProcessWindowData
{
public:

    ProcessWindowData(DWORD dwProcessId) :
        m_dwProcessId(dwProcessId),
        m_hWnd(0)
    {
        ASSERT(0 != dwProcessId);
    }

    DWORD ProcessId()
    {
        return m_dwProcessId;
    }

    void WindowHandle(HWND hWnd)
    {
        ASSERT(0 != hWnd);
        m_hWnd = hWnd;
    }

    HWND WindowHandle()
    {
        return m_hWnd;
    }

private:

    DWORD m_dwProcessId;
    HWND m_hWnd;
};

DWORD GetWindowProcessId(HWND hWnd)
{
    ASSERT(0 != hWnd);
    DWORD dwProcessId = 0;

    ::GetWindowThreadProcessId(hWnd, &dwProcessId);

    ASSERT(0 != dwProcessId);
    return dwProcessId;
}

BOOL CALLBACK EnumWindowProc(HWND hWnd,
                             LPARAM lParam)
{
    ASSERT(0 != hWnd && 0 != lParam);
    BOOL bContinue = TRUE;

    ProcessWindowData* pData = reinterpret_cast<ProcessWindowData*>(lParam);

    if (pData->ProcessId() == GetWindowProcessId(hWnd))
    {
        pData->WindowHandle(hWnd);
        bContinue = FALSE;
    }

    return bContinue;
}

HWND GetProcessWindow(DWORD dwProcessId)
{
    ASSERT(0 != dwProcessId);
    ProcessWindowData data(dwProcessId);

    ::EnumWindows(EnumWindowProc, reinterpret_cast<LPARAM>(&data));

    return data.WindowHandle();
}

How to use it
void CSampleDlg::RunNotePad()
{
   STARTUPINFO si;
   PROCESS_INFORMATION pi;

   ZeroMemory( &si, sizeof( STARTUPINFO ));

   si.cb = sizeof( STARTUPINFO );

   ZeroMemory( &pi, sizeof( PROCESS_INFORMATION ));

   char Fname[MAX_PATH];
   strcpy(Fname,"c:\\winnt\\Notepad.exe");
   if
(CreateProcess(Fname,Fname,NULL,NULL,FALSE,NORMAL_PRIORITY_CLASS,NULL,NULL,&
si,&pi))
   {
      WaitForInputIdle(pi.hProcess,INFINITE);
      m_OtherhWnd = GetProcessWindow(pi.dwProcessId);
   }
}

void CSampleDlg::OnSize(UINT nType, int cx, int cy)
{
   if (nType == SIZE_MINIMIZED)
   {
      ::ShowWindow(m_OtherhWnd,SW_MINIMIZE);
   }
   else if (nType == SIZE_RESTORED)
   {
      ::ShowWindow(m_OtherhWnd,SW_RESTORE);
   }

   CDialog::OnSize(nType, cx, cy);
}
