I am developing an ASP.net 2.0 web site for an existing
classic VS 6 project.  Just noticed that the URL's of some
classic ASP pages were shown with ServerName/RootFolderName only.
Another unique feature of these pages is that the link and
the date on the ASP page were automatically changed in response
to updating an ASP file into the server.  For example, a link named  
by ABC.asp - 7/1/2007 will change to ABC.asp - 7/15/2007, after I
inserted an updated ABC.asp to the server folder today, i.e 7/15/2007.

1. Can I create a similar ASP.NET 2.0 page with ABC.asp - 7/15/2007? How?  
2. Is "ABC.asp - date" a good ASP.net 2.0 presentation?

TIA,
Jeffrey

You could make a user control like below.  Save the code to HyperLinkWithDate.ascx, add the file to your project, drag and drop the control onto a page and set the control's HyperLink.NavigateUrl property to a file.

<%-- HyperLinkWithDate.ascx--%>

<%@ Control Language="C#" ClassName="HyperLinkWithDate" %>

<script runat="server">

    // ---- DateLabel_Load -------------------------------
    //
    // get the file date of the file in the hyperlink and
    // display it.
    
    protected void DateLabel_Load(object sender, EventArgs e)
    {
        DateTime FileDate;
        
        // assumes NavigateUrl is of form ~\MyFile.aspx
        FileDate = System.IO.File.GetLastWriteTime(Server.MapPath(HyperLink.NavigateUrl));     

        DateLabel.Text = FileDate.ToString(": d-M-yyyy");       
    }
    
</script>

<asp:HyperLink ID="HyperLink" runat="server" NavigateUrl="~/Default2.aspx" >Default2.aspx</asp:HyperLink>
<asp:Label ID="DateLabel" runat="server" Text="Label" OnLoad="DateLabel_Load" ></asp:Label>

Thanks.

I have coded the user control.  It worked very well, except that it showed 24-16-2007
for 07/16/2007 12:24 PM of my aspx file.  I tried different date formates, e.g. mm/dd/yyyy,
or dd/mm/yyyy, it still showed "24" month.  Not sure what's wrong.

Thanks.  Another question on creating the ascx files.

1. If I have 10 links on an aspx web page, I have to create and drop 10 ascx files for 10 links?

2. I have used a table to list my <a href="http://..."> on each TD.  Can I code the DateLabel_load
    directly behind the <a href="http...> without using the user control?

3.  I have used Visual Baisc for my aspx web site.  Adding user controls with C# should be okay.
     Am I correct?

TIA,
Jeffrey

Note the MM-mm is case sensitive.  You are getting minutes not Months.

>> Can I code the DateLabel_load directly behind the <a href="http...> without using the user control? 

Sure.

Try it and see :)

By the way, I forgot to expose properties you can set in the properties window: 

<%-- HyperLinkWithDate.ascx--%>

<%@ Control Language="C#" ClassName="HyperLinkWithDate" %>

<script runat="server">

    // ---- DateLabel_Load -------------------------------
    //
    // get the file date of the file in the hyperlink and
    // display it.
    
    protected void DateLabel_Load(object sender, EventArgs e)
    {
        DateTime FileDate;
        
        // assumes NavigateUrl is of form ~\MyFile.aspx
        FileDate = System.IO.File.GetLastWriteTime(Server.MapPath(HyperLink.NavigateUrl));     

        DateLabel.Text = FileDate.ToString(": d-M-yyyy");       
    }

    public String NavigateUrl
    {
        get { return HyperLink.NavigateUrl; }
        set { HyperLink.NavigateUrl = value;}
    }
    public String HyperLinkText
    {
        get { return HyperLink.Text; }
        set { HyperLink.Text=value;}
    }   
    
</script>

<asp:HyperLink ID="HyperLink" runat="server" NavigateUrl="~/Default2.aspx" >Default2.aspx</asp:HyperLink>
<asp:Label ID="DateLabel" runat="server" Text="Label" OnLoad="DateLabel_Load" ></asp:Label>

Now the usage is:

        <uc1:HyperLinkWithDate ID="HyperLinkWithDate1" runat="server"  HyperLinkText="Default1.aspx"  NavigateUrl="~\Default1.aspx" />
        <uc1:HyperLinkWithDate ID="HyperLinkWithDate2" runat="server"  HyperLinkText="Default2.aspx" NavigateUrl="~\Default2.aspx"/>

Yes, I have started coding using C# user control and it worked fine except for the mm problem. 
After correcting the MM/mm problem, the user control worked perfectly.

Then I tried to use in-line coding to code directly the DateLabel_Load into my aspx source file.
Because my aspx file was coded by Visual Basic, I modified your DateLabel_Load C# to VB
codes and tried several times.  My VB codes did not work for label_load.

Some error msg are:
  'DateTime' is a type and cannot be used as an expression.
   Error 1 'FileDate' is not a member of 'Date'.

Can you give me some sample VB codes for defining the MapPath for links to other aspx files and
href url's?  

TIA,
Jeffrey

Thanks.

Yes, I have written the VB code for a user control and have successfully showed the DateLabel Text.

Then I wrote an in-line VB code into the aspx file with a href http link and received an error msg that
the http file can not be found. Apparently the MapPath() works only for local file.  How do I code the
file.GetLastWriteTime() for a http link?

TIA,
Jeffrey

Just tried the inline VB code:

 Protected Sub DateLabel4_Load(ByVal sender As Object, ByVal e As System.EventArgs)
        Dim FileDate As DateTime
        FileDate = System.IO.File.GetLastWriteTime("\\sca4001\DARS DDS\Home.aspx")
        DateLabel4.Text = FileDate.ToString(": MM/dd/yyyy")
    End Sub

sca4001 is my other server.  Many times, including the local server,
the FileDate seemed to be working, but the label date was 12/31/1600.
What does 12/31/1600 mean?  The coding was correct, but the ToString was wrong?
Or the FileDate is still wrong, so the filedate is empty?

TIA,
Jeffrey

What does 12/31/1600 mean? 

Online Help:  If the file described in the path parameter does not exist, this method returns 12:00 midnight, January 1, 1601 A.D. (C.E.) Coordinated Universal Time (UTC), adjusted to local time.

Thanks.

I changed the path to C:\Inetpub\wwwroot\....; then the FileDate worked and
the correct date was shown in the Label control.  Apparently, the File.GetLastWriteTime 
worked strictly only for local c: drive files, not for http or network files..

Thanks,
Jeffrey
