In this episode of Defrag Tools, Andrew Richards and Larry Larsen continue looking at the Debugging Tools for Windows (in particular WinDbg). WinDbg is a debugger that supports user mode debugging of a process, or kernel mode debugging of a computer.This installment shows how you can view the user mode call stack and stack variables in a native, managed (.NET) or Silverlight process. We use these commands:dvdt!sos.dumpstack!sos.dumpstackobjects / !sos.dso!sos.dumpobj / !sos.do!sos.printexception / !sos.pe.frame.f+.f-.load.unload.loadby.chainlm / lmm / lmvm.extmatch.prefer_dml 1.lines.ecxr.clsMake sure you watch Defrag Tools Episode #1 for instructions on how to get the Debugging Tools for Windows and how to set the required environment variables for symbols and source code resolution.
