title: Could I create a MFC DLL for Metro apps to use?
body: <p>I've post this question on MSDN (http://social.msdn.microsoft.com/Forums/en-US/winappswithhtml5/thread/9da1b0e4-6a03-41b2-b68e-6fefb4729c52). If it is considered as duplicated question, please remind me to delete it. Thanks.</p>
  
  <p>I am using VS2012 pro on Win8 Pro. I encountered an issue and needs your help:</p>
  
  <p>Let me simplify the scenario: Metro App (JavaScript) calls DLL1(a Windows Runtime Component), and DLL1 calls DLL2(a MFC DLL).</p>
  
  <p>After I created a MFC DLL, then from "Configuration Properties", I changed the "use of MFC" as "Use Standard Windows Libraries", and changed "Windows Store App Support" as "Yes". But My Metro App always said that "0x8007007e - JavaScript runtime error: The specified module could not be found." After debugging, I found that the error is caused by DLL2. But I don't know why it is caused.</p>
  
  <p>Does anybody know anything about this? Or would you please give me some hint?</p>
  
  <p>Thank you all.</p>
