title: How to fire following command from vc++?
body: <p>I want to change image's exif data. For that I've used <a href="http://www.exiv2.org/download.html" rel="nofollow">Exiv2.exe</a>. Now I want to fire command from my program which is written in vc++ 08. For modify GPS data of image, exive command is</p>
  
  <p><code>exiv2 -M"set Exif.GPSInfo.GPSLatitude 4/1 15/1 33/1" D:\test\image.jpg</code></p>
  
  <p>I've placed exiv2.exe into system32 folder. And this command works fine from command prompt. For example,</p>
  
  <pre><code>C:\Users\Me&gt;exiv2 -M"set Exif.GPSInfo.GPSLatitude 4/1 15/1 33/1" D:\test\image.jpg
  </code></pre>
  
  <p>Now how can I fire this same command from my c++ program?</p>
  
  <p>Thanks in advance...</p>
