title: win32gui.FindWindow Not finding window
body: <p>I'm trying to send a keystroke to an inactive TeraTerm Window using Pywin32. </p>
  
  <p><a href="https://stackoverflow.com/a/38888131/3714940">This</a> answer led me to write this code:</p>
  
  <pre><code>import win32gui
  import win32con
  import win32api
  
  hwndMain = win32gui.FindWindow("Tera Term VT", None)
  print hwndMain
  hwndChild = win32gui.GetWindow(hwndMain, win32con.GW_CHILD)
  win32api.PostMessage(hwndChild, win32con.WM_CHAR, 0x5b, 0)
  </code></pre>
  
  <p>but:<br>
  <code>hwndMain = win32gui.FindWindow("Tera Term VT", None)</code> returns <code>0</code>, it can't find the window. </p>
  
  <p>If I change <code>"Tera Term VT"</code> to <code>"Notepad"</code>, I can happily send keystrokes to an active Notepad window all day long. So, why can't I  get the TeraTerm window?</p>
  
  <p>According to the <a href="http://docs.activestate.com/activepython/2.7/pywin32/win32gui__FindWindow_meth.html" rel="noreferrer">ActiveState documentation</a>:</p>
  
  <blockquote>
    <p>PyHANDLE = FindWindow(ClassName, WindowName)</p>
    
    <p>ClassName : PyResourceId
    Name or atom of window class to find, can be None<br>
    WindowName : string
    Title of window to find, can be None</p>
  </blockquote>
  
  <p>So how can I get the correct ClassName to use?</p>
  
  <p>I've tried just about every variation of <code>Tera Term VT</code>, escaping the spaces: <code>"Tera\ Term\ VT"</code>, enclosing the whole in single quotes: <code>"'Tera Term VT'"</code>, but nothing works. I've even tried using the name of the process:<code>"ttermpro.exe"</code>, and included the child name in the string <code>"COM11:115200baud - Tera Term VT"</code> in my desperation, but nothing works.</p>
  
  <p>Interestingly,  this:</p>
  
  <pre><code>import win32com.client
  
  shell = win32com.client.Dispatch("WScript.Shell")
  shell.AppActivate("Tera Term VT")
  shell.SendKeys("\%i", 0)
  </code></pre>
  
  <p>works just fine, but brings the window to the foreground, which I don't wan't. The <code>Tera Term VT</code> string works fine in this instance though.</p>
