title: How do I force my app to come to the front and take focus?
body: <p>I'm working on an application that happens to be the bootstrap for an installer that I'm also working on. The application makes a few MSI calls to get information that I need for putting together the wizard that is my application's main window, which causes a progress window to open while the info is being gathered and then go away once that's done. Then the wizard is set up and launched. My problem is that the wizard (derived from CPropertySheet) does not want to come to the front and be the active application without me adding in some calls to do so.</p>
  
  <p>I've solved the problem of bringing it to the front with the following code in my OnInitDialog() method:</p>
  
  <pre><code>SetWindowPos(&amp;wndTopMost, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE); // force window to top
  SetWindowPos(&amp;wndNoTopMost, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE); // lose the topmost status that the previous line gave us
  </code></pre>
  
  <p>My problem is that I still haven't figured out how to make the window self-activate (i.e., make itself be the one that has the focus). SetFocus() won't work in this context. I need something that will force the window to the top of the Z-order and activate it, preferably in as few calls as possible.</p>
  
  <p>My guess is that the progress window opened at the beginning by the MSI calls is causing the main window to screw up, but I have no way to prevent that window from appearing. Also, it wouldn't make sense to hide it, because it lets the user know what's going on before the main window arrives.</p>
