It was fine before and now it's error where it never error before. Same project is fine when open on other computer.
I search on google.com & microsoft.com but I didn't found any case that same as mine.
My computer was W2K. I already re-install VS2005, .net 2.0 a few time but it still didn't work. I did re-install everything on Windows XP. It seems fine for a couple weeks then this error came back after I run windows updates last week.
My computer have both VS 2003 & VS 2005. Some of my company's customer servers still run application on .NET 1.1 and some are .NET 2.0 and I'm not sure if it will be any problem if I use VS 2005 to recompile old programe that compile on VS 2003 before so I keep both. My supervisor want everybody to use it even though I'm not fully understand about what difference between these two. I just start write C# Windows Form about last year and yet much things to learn.
If anybody could give me some advice, please let me know. I'll appreciate that.
