The problem that I got was while passing the same above query in the code that I had written in VB.strSQL="select column1 as "{Ctrix}" from table;" The query is getting truncated and giving error. Please help me, how to handle this properly at sql/vb... which satisfies both.

I've got a program that in a nutshell reads values from a SQL database and writes them to a tab-delimited text file.The issue is that some of the values in the database have special characters (TM, dash, ellipsis, etc.) When written to the text file, the formatting is lost and they come across as junk "â„¢ or â€" etc"
When the value is viewed in the immediate window, before it is written to the txt file, everything looks fine. My guess is that this is an issue of encoding. But, I'm not real sure how to proceed, where to look, or what to look for.Is this ASCII or UTF-8? If it's one of those how do I correct it before it's written to the text file.Here's how I build the text file (where feedStr is a StringBuilder)
objReader = New StreamWriter(filePath)
objReader.Write(feedStr)
objReader.Close()
this would be my string Panipat,Patna,Result should be Panipat,Patna,Panipat,Patna,Result should be Panipat,Patna Panipat,Result should be Panipat,Panipat,,Result should be Panipat How can i do it

I have the above declarations in my project. On a Vista machine the compiled code looks good, on a XP machine I get a character like this [] instead. I copied the code from the web, I'm not even sure how it was typed to begin with.

I'm working on a form in which strings of text are being imported. A lot of these strings contain special characters, like �, �, �, &, �, etc...
When I convert these strings to text, so they can be shown as labels, the special characters either disappear (like the '&' sign) or they are shown as some sort of icons. How can I let VB handle these strings, so the special characters are shown the way they should, without having to change the (many hundreds) original strings of text?
