Dependency Walker
I was trying to figure out what are the dependencies for a OCX file which I was trying to package. Since I had only Visual Studio .NET in my system, I did'nt have a Dependency Walker (depends.exe).
A brief search in Google revealed this website http://www.dependencywalker.com/ which is the same tool that gets shipped with Visual Studio 6.0. I wanted to share this with my readers of the blog too for their use and reference.
