Dave the @ symbol seems to me that it means at _new but the rest (?<count>\d+) what is it that its doing.
The rest makes sense to me.

You should be able to translate it, or someone on here might be able too. string fn = "my_pic_new2.jpg"; Regex r = new Regex( @"_new(?<count>\d+)" ); Match m = r.Match( fn ); if( ( m != null ) && ( m.Groups[ "count" ].Value.Length >0 ) ) { string current = m.Groups[ "count" ].Value; int next = int.Parse( current ) + 1; fn = fn.Replace( "_new" + current, "_new" + next.ToString() ); } Cheers!

Lets say I have a file name is my database my_pic_new1.jpg first off. Now I want to change this file name to make it a uniqe file name but I need to do a few things to the string first. Is in the string _new is there then I want to see if a number is there. If there is a number there I want to take that number and what ever it is increment that number up by one make the file now my_pic_new2.jpg and so on. I am not asking for someone to write the code for me but point me to where I can gain viable info on how to make this hapeen or a small code example. Here is my code at present, Dim words1 as String = tmnescort_currentpic_small Dim location as Integer Dim Counter as Integer Dim newstr as Integer Dim newstring_withnum as Integer Dim countvar as Integer Dim newstring_withnum_tostr dim addnum as String Counter = 0 location = words1.IndexOf("_new") If location > 0 or not -1 then newstring_withnum_tostr = instr(1, words1, "1") newstr = System.Convert.ToInt16 (newstring_withnum_tostr + 1) newstring_withnum = newstr & Counter + 1 addnum = System.Convert.ToString(newstring_withnum) str_msg.Visible = True str_msg.Text = "This is the pic name in DB " & tmnescort_currentpic_small & "<br><br>new string was found<br><br>" & addnum & "<br><br>" else str_msg.Visible = True str_msg.Text = "This is the pic name in DB " & tmnescort_currentpic_small & "<br>new string was not found<br><br>" & addnum & "<br><br>" end if what I get back printed out is This is the pic name in DB my_pic_new1.jpg new string was found 161 << this is what happens after my string manipualtion I dont want this. Can any please help me? Thanks, Tony... ------------------------------------------------------------------------------ Yahoo! Groups Links a..
