Two things I learned this morning and it's not even 7AM yet.
You can open up an image in Paint.NET in the File Open dialog by specifying a URL to an image on the internet. I'm assuming this is nothing new and maybe any File Open dialog can do this (not sure) but it works in Paint.NET. I was opening a file that I though I had copied the local path name in the clipboard. Instead I had the URL to it on a website. So I let it go and do it's thing and lo and behold it had brought the image down and opened it up for me in Paint.NET. Cool.
Visual Studio (2005) holds a reference to your solution files even if you select File | Close Solution. This has bugged me for awhile but I was re-syncing my local folder with what was in TFS and needed to blow away my local directory. I selected File | Close Solution and waited a bit, then proceeded to delete the files. Up until recently, I just installed SysInternals file locker unlocker tool and up it popped telling me that msdev.exe had a hold on the files. No matter what I did I couldn't tell Visual Studio to let my files go (even opening another solution). So the only way to delete a directory of a project you've opened is to shut Visual Studio down. Very annoying to say the least.
Wonder what the rest of the day holds?
