title: find bug position in source code during vc debugging
body: <p>I created a DLL. The source codes can be compiled and linked. During running, it works normally somehow, but in certain situations it crashes. At this point, VC just shows me a window to ask me whether to Break or Continue，but it doesn't tell where the error in the code is. </p>
  
  <p>My question is, is it possible to configure the VC debugging in any way so that a breakpoint is directly set at the code position where the error happened? Or how can I find the source code bug position?</p>
  
  <p>P.s. I use VC Express 2010</p>
