Lost the source code to a DLL!

Question

Hi,

Years ago I developed a label printing program for my company and now they've decided to change the company name and logo. I build the label with an image of the company logo in a separate class file. First time I've looked at this code since, well, I developed it using VS 2012.

But now I find I don't seem to have the original code for that separate class file and management really wants the logo changed. I'm guessing it was on the local hard drive of a workstation I disposed of, probably, 5 or 6 years ago.

Any thoughts on how to reverse engineer this DLL or am I doomed to try and re-invent the wheel? Programming isn't my primary function so it will be a challenge to recreate this. I have no idea what I originally did or where I got my inspiration.

Thanks in advance!
