i need to disallow \n\t

 

by: jedistarPosted on 2006-05-24 at 07:42:11ID: 16751807

i think u made it such that it allows \n\t

 

by: nurbekPosted on 2006-05-24 at 07:45:12ID: 16751839

you may use replace function

str = Replace(str,vbCrlf," ")

what do you mean by dissallowing \n\t? (remove them?)

do not the syntax in asp.net
it is in asp
it finds \n\r\t and replaces with white space

     Set objRegExpr = New regexp
     objRegExpr.Pattern = "[\n\t\r]"
     objRegExpr.Global = true
     objRegExpr.IgnoreCase = true
     newStr = objRegExpr.Replace(str," ")
     Set objRegExpr = Nothing
     Response.Write(newStr)

You can use a RegularExpressionValidator like this.

<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" ErrorMessage="Tab or CR is not allowed" ControlToValidate="TextBox1" ValidationExpression="[^\t\n]*"></asp:RegularExpressionValidator>

      {
            string data = mStr.ToString();
            data = data.Replace("\n", "<br>");
