Hi

Firstly I am using FreeTextBox to edit a document in the browser. I wish to provide the function to user where they can choose to either save to the server or download to the desktop... I am having a small problem with my code... The file opens ok but the document includes not only the content from my textbox but also the whole pages html.

the code --  

17               'Try to write the file to the stream for user download. 
18               Try
19                   If DropDownSaveTo.SelectedValue = ("Desktop") Then
20                       '' Open the stream and read it back.
21                       fsdoc = File.Open(doc, FileMode.Open, FileAccess.Read)
22                       Response.AddHeader("Content-Disposition", "attachment; filename=" & docname.Text & DropDownList1.Text)
23                       Response.ContentType = "text/octet-stream"
24                       Dim b(1024) As Byte
25                       Dim temp As UTF8Encoding = New UTF8Encoding(True)
26                       Dim sw As New StreamWriter(Response.OutputStream)
27   
28                       Do While fsdoc.Read(b, 0, b.Length) > 0
29                           sw.Write(temp.GetString(b))
30                           sw.Close()
31                       Loop
32                       fsdoc.Close()
33                   End If
34               Catch ex As Exception
35                   Response.Write(ex)
36           End If

 This has the effect of writing the document from the contents of freetextbox and then downloading the document.... problem is the document looks something like  

FTBv3-1-6/editor.aspx?info.text=Done'>Welcome to Document Editor 
User Interface version 1.0. To get started simply use the buttons 
to edit, save or print documents in this window.


<input type="hidden" name="__WPPS" id="__WPPS" value="u" />
<input type="hidden" name="__EVENTTARGET" id="__EVENTTARGET" value="" />
<input type="hidden" name="__EVENTARGUMENT" id="__EVENTARGUMENT" value="" />
<input type="hidden" name="__LASTFOCUS" id="__LASTFOCUS" value="" />

When it should look like  
Welcome to Document Editor User Interface version 1.0. 

To get started simply use the buttons to edit, save or print 
documents in this window.
 
Anyone any ideas ?

Hi mal,

Base on my experience, you can use regular expression(<[^>]*>) to solve your problem, see the following demo:

    protected void Page_Load(object sender, EventArgs e)
    {
        string HTML = @"
                        <form id='form1' runat='server'><div>
                        <asp:TextBox ID='txtAnimalID'runat='server'>I </asp:TextBox>
                        <asp:TextBox ID='txtCordX' runat='server'>Love </asp:TextBox>
                        <asp:TextBox ID='txtCordY' runat='server'>ASP.NET</asp:TextBox>
                        </div></form>";
        HTML = GetTextFromHTML(HTML);
    }

    string GetTextFromHTML(string strHtml)
    {
        string temp = System.Text.RegularExpressions.Regex.Replace(strHtml, "<[^>]*>", "");
        return temp.Replace(" ", " ");
    }

NOTE: Running above code, the HTML variable will get "I Love ASP.NET", there is no any HTML tag in it.

Let me know if I have misunderstood what you mean. Thanks.

Hope it helps,

Hi mal,

Sorry, it seems you are familiar whit VB, but I am familiar with C#, but do not worry, you can use this to convert my code to VB if you do not familiar with C#:

Hi Hong Gang.

Thanks for the reply. I think you did understand my question very well! I used the covert function to see the vb.net code

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) 
    Dim HTML As String = "" & Chr(13) & "" & Chr(10) & " <form id='form1' runat='server'><div>" & Chr(13) & "" & Chr(10) & " <asp:TextBox ID='txtAnimalID'runat='server'>I </asp:TextBox>" & Chr(13) & "" & Chr(10) & " <asp:TextBox ID='txtCordX' runat='server'>Love </asp:TextBox>" & Chr(13) & "" & Chr(10) & " <asp:TextBox ID='txtCordY' runat='server'>ASP.NET</asp:TextBox>" & Chr(13) & "" & Chr(10) & " </div></form>" 
    HTML = GetTextFromHTML(HTML) 
End Sub 

Private Function GetTextFromHTML(ByVal strHtml As String) As String 
    Dim temp As String = System.Text.RegularExpressions.Regex.Replace(strHtml, "<[^>]*>", "") 
    Return temp.Replace(" ", " ") 
End Function 

 I have yet to get back to my project to test this and will get back to you asap.

Kind Regards
