HI guys, got a bit of a problem, (probably quite easy to sort out)
I'm writing html generated by my program to a text file, but im having a problem with Quotes, i either get too many or none at all,
THIS CODE:
Dim strRanTemp As String = "<area shape=" & ControlChars.Quote & "rect" & ControlChars.Quote & " coords=" & ControlChars.Quote & "522,75,628,93" & ControlChars.Quote & " href=" & ControlChars.Quote & TextBox2.Text & ControlChars.Quote & " target=" & ControlChars.Quote & "_top" & ControlChars.Quote & " alt=" & ControlChars.Quote & TextBox1.Text & ControlChars.Quote & " />"
        SaveTextToFile(strRanTemp, "htmlCode.txt")
GIVES THIS RESPONSE:
"<area shape=""rect"" coords=""522,75,628,93"" href=""5.c"" target=""_top"" alt=""5"" />"
"<area shape=""rect"" coords=""522,75,628,93"" href=""6.c"" target=""_top"" alt=""6"" />"

It seems to give double quotes and a quote at the beggining and the end

And if i leave the           & ControlChars.Quote         out then i get this:
"<area shape=rect coords=522,75,628,93 href=60.com target=_top alt=60 />"

Could anyone sort this out please? thanks

Hi dajoebomb,

I tried your code with the ControlChars.Quote and it worked fine, but I only tested with a MsgBox....

        Dim strRanTemp As String = "<area shape=" & ControlChars.Quote & "rect" & ControlChars.Quote & _
                                   " coords=" & ControlChars.Quote & "522,75,628,93" & ControlChars.Quote & _
                                   " href=" & ControlChars.Quote & TextBox2.Text & ControlChars.Quote & _
                                   " target=" & ControlChars.Quote & "_top" & ControlChars.Quote & _
                                   " alt=" & ControlChars.Quote & TextBox1.Text & ControlChars.Quote & " />"
        MsgBox(strRanTemp)

Whet does the SaveTextToFile() routine do? Can you post it here?

Regards,

Wayne

An alternate to using ControlChars.Quote is to use them literally....

        Dim strRanTemp As String = "<area shape=""rect"" coords=""522,75,628,93"" href=""" & _
                                   TextBox2.Text & """ target=""_top"" alt=""" & TextBox1.Text & """ />"

Try our this

Dim strRanTemp As String = "<area shape='rect' coords='522,75,628,93' href='" & TextBox2.Text & "' target='_top' alt='" & TextBox1.Text & "' />"

Hi webtubbs, thanks for your speedy reply
Here is the function as you requested:

Public Function SaveTextToFile(ByVal strData As String, ByVal FullPath As String)
 Dim bAns As Boolean = False
Try
FileOpen(1, FullPath, OpenMode.Append)
            WriteLine(1, strData)
            bAns = True
        Catch Ex As Exception
            ErrInfo = Ex.Message

        End Try
        FileClose(1)
        Return bAns
    End Function

Joe,

FileOpen is 'old school' VB6 code, but I can't see why it wouldn't work. Perhaps try this native VB.Net function....

    Public Function SaveTextToFile(ByVal strData As String, ByVal FullPath As String)
        Dim bAns As Boolean = False
        Try
            Dim sw As New IO.StreamWriter(FullPath, True)
            sw.Write(strData)
            sw.Close()
            bAns = True
        Catch Ex As Exception
            ErrInfo = Ex.Message
        End Try
        Return bAns
    End Function

Try our this

Dim strRanTemp As String = "<area shape='rect' coords='522,75,628,93' href='" & TextBox2.Text & "' target='_top' alt='" & TextBox1.Text & "' />"

Thanks Webtubbs,
That function and the
Dim strRanTemp As String = "<area shape=""rect"" coords=""522,75,628,93"" href=""" & _
                                   TextBox2.Text & """ target=""_top"" alt=""" & TextBox1.Text & """ />"
Worked great.
THanks Again!
