So you’re getting IIS error’s when trying to run a .svc file that’s coded to use WCF or Windows Communication Foundation.

HTTP Error 404.17 - Not Found

The requested content appears to be script and will not be served by the static file handler.

or maybe..

HTTP Error 404.3 - Not Found

The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map.

Took me awhile to realize I need to setup/configure IIS and WCF properly.  Here are the steps from MS, I went through and realized I had missed one component (IIS6 Scripting tools, who would have thought), which I probably didn’t need, but the big ones that I didn’t have WCF Http Activation installed.  After that, I registered WCF..

"%WINDIR%\Microsoft.Net\Framework\v3.5\WFServicesReg.exe" /c

and then I was golden, but there might be other things you are lacking or missing. So go through all the steps.

Ok if you google this you’ll get some solutions that say set the DefaultButton to ParentControlID$ButtonID

However, this didn’t work for me. I kept getting the same error no matter what I tried.

The DefaultButton of '<PanelID>' must be the ID of a control of type IButtonControl.

So I tried another approach that worked great.

On page load I found the Panel Control and found the button control and set the default button programmatically.

<asp:LoginView ID="LoginView1" runat="server">

    <AnonymousTemplate>

        <asp:Panel ID="pnlLogin" runat="server">

            <telerik:RadTextBox ID="tbUsername" runat="server" EmptyMessage="Username" />&nbsp;

            <telerik:RadTextBox ID="tbPassword" runat="server" EmptyMessage="Password" TextMode="Password" />&nbsp;

                 <asp:LinkButton ID="lbSignIn" runat="server" Font-Bold="true" Font-Size="Small" Text="SIGN IN" OnClick="lbSignIn_Click" />

Reference a control that’s is outside your View, or on your MainPage if you’re using NavigationFrame or your “Parent” window.

Assumption: MainPage UserControl page is your starting page and has a NavigationFrame and a View is loaded in a content window.

Method 1: (Assuming “MainPage” is the name of your MainPage or the x:Class it uses, x:Class="<AppName>.MainPage" and the TextBlock named “lblStep1”)

Dim Main As MainPage = CType(<AppName>.App.Current.RootVisual, MainPage)
        CType(Main.FindName("lblStep1"), TextBlock).Text = "Hello Test123"

Or Method 2:

CType(CType(<AppName>.App.Current.RootVisual, MainPage).FindName("lblStep1"), TextBlock).Text = "Updated Text"

Reference a Control in a User Control that’s on the same view.

As a developer I always have to write code to send emails, here's a quick way as a developer to make sure the SMTP Server is working properly.

Telnet to Port 25 to Test SMTP Communication

1. Telnet into Exchange or SMTP Server using port 25.
Command is telnet <servername> 25

c:\>telnet 192.168.0.5 25
220 fredmastro.com Microsoft ESMTP MAIL Service, Version: 6.0.3790.1830 ready at  Sun, 29 Nov 2009 10:22:22 -0400

2.Start by typing the following:
helo <your domain name><enter>                 
response should be as follows
250 OK

c:\>helo
250 fredmastro.com Hello [10.x.x.x]

3. Type the following command to tell the receiving SMTP server who the message is from:

mail from: <your Email Address><enter>
response should be as follows
250 OK - mail from <your Email address>

For example,

c:\>mail from: fredmastro@fredmastro.com
250 2.1.0 fredmastro@fredmastro.com....Sender OK

4.Type the following command to tell the receiving SMTP server whom the message is to. Use a valid recipient SMTP address in the domain that you are sending to.

For example, if you are sending to someguy@gmail.com, you must be certain that someguy@gmail.com exists in your domain. Otherwise, you will receive an NDR.

rcpt to: <recipient address><enter>
response should be as follows
250 OK - Recipient <recipient address>

For example, 
c:\>rcpt to: someguy@gmail.com
250 2.1.5 someguy@gmail.com

5.Type the following command to tell the SMTP server that you are ready to send data:

data<enter>
response should be as follows
354 Send data.  End with CRLF.CRLF

c:\>data
354 Start mail input; end with <CRLF>.<CRLF>
Test Message
.

250 2.6.0 <someguy@gmail.com>
 Queued mail for delivery

6. Close the connection by typing the following command:
c:\>QUIT
