title: A custom action that reads the file and stores a value in session obj. Is there a way to use it as a property while invoking othr custom action
body: <pre><code>&lt;CustomAction I'd=readValue binaryKey = custom.dll 
      DllEntryy = readfilevalue Execute= deferred Return = 
    check/&gt;
  
  // // In a .cs file code to read the file having method 
  </code></pre>
  
  <p>//    readfilevalue.
     //     I am setting 
         Customsession.writesessionvalue(key, value);</p>
  
  <pre><code>//   In another .wxs file invoking executables
    &lt;Custom Action = someExe After= someOtherExe&gt;
           &lt;!CDATA[  key &lt; someValue]&gt;
    &lt;Custom&gt;
  </code></pre>
