Convert absolute path to relative path

Today I needed to convert an absolute path to a relative path based on a specified base path. E.g. c:\a\b\c -> c:\a\b\c\d\file.txt = d\file.txt c:\a\b\c -> c:\a\file.txt = ..\..\file.txt c:\a\b\c -> c:\a\x\file.txt = ..\..\x\file.txt I am surprised there is nothing in the .NET framework so I had a hunt around and converted the code from the following URL ( ) into C#.... private string RelativePath(string absolutePath, string relativeTo) { string[] absoluteDirectories = absolutePath.Split('\\'); string[] relativeDirectories = relativeTo.Split('\\'); //Get the shortest of the two paths int length = absoluteDirectories.Length < relativeDirectories.Length ? absoluteDirectories.Length : relativeDirectories.Length; //Use to determine where in the loop we exited int lastCommonRoot = -1;

Acer Skoda - I mean Ferrari

I have owned an Acer Ferrari now for approximately 13 months. Previously I had a problem with it freezing randomly. I spent some time trying to reproduce the problem and after a month or two was finally able to reproduce it 100% of the time. I sent my laptop back to Acer armed with exact steps and as a result my laptop was returned to me after only a couple of days. For the past 2-3 months I have been seeing very rare, random resets. Obviously I blamed Windows, as you do :-) Some software I had to convert AVI to MPEG would always reset the laptop, but I just put that down to dodgy software. More recently I noticed that 7-zip would also reset my laptop *only* if I used ULTRA compression on a file larger than 500MB. So I tried Winzip, same problem. I installed Vista and tried both Winzip and 7-zip in there, same problem. With steps to reproduce + proof that it was not the OS I felt I could finally send the laptop back for repair without running the risk of it coming back "


Someone sent me this on Skype this morning. I think it's really cool, it reminds me of the hardware sprites on the old Commodore 64! 01: Go to any site with lots of images (image search on google is a good one) 02: Once the images appear copy/paste this text into your address bar. javascript:R=0; x1=.1; y1=.05; x2=.25; y2=.24; x3=1.6; y3=.24; x4=300; y4=200; x5=300; y5=200; DI=document.images; DIL=DI.length; function A(){for(i=0; i<DIL; i++){DIS=DI[ i ].style; DIS.position='absolute'; DIS.left=Math.sin(R*x1+i*x2+x3)*x4+x5;*y1+i*y2+y3)*y4+y5}R++}setInterval('A()',5 ); void(0);
