In a vb.net 2010 web form application the user loads 'template letters' to a web inerface, so that they can modify letters sent out to various customers to generate various late pay notifications. The user basically selects the 'template letter' they want to generate for a specific customer, and hits the 'save' button.
The web interface has the tabs for 'preview', 'html', and 'design' as the bottom of the editor. These tabs are not part of any custom code, they must be part of a web interface that is inherited.
The values for the editor are stored in a sql server 2012 database in a field called 'strTemplate' and the value is actually html.
The problem is once the html value for 'strTemplate' is loaded for the user to edit, extra blank lines are loaded between different parts of the 'templates'. Basically extra
tags are generated.
When the user hits the save button, more
tags are generated between the various parts of the letter.
I do not want these extra blank lines to be generated.
I have gone into the html tab, removed the
tags and hit the save button. The extra tags are still generated. I have stepped through the code to find where the tags are generated and can not find it.
Thus can you tell me what I can do to not have the extra
tags generated?
The following is some of the code that is used when accessing the part of that gets to the web interface:

Hi, The following code selects and displays a record from the "emailtbl" table
as desired except for the the date and it doesn't update the "lastused" (date)
field to the "numbers" table via "lastused.php" include. No error messages. I need help.
<pre lang="PHP"><html><head>
</head>
<BODY>
="''"=mysqli_connect(==============";}
// ==========This creates the drop down box using records in the table
echo "<select name= 'target'>";
echo '<option value="">'.'---select email account ---'.'</option>';
$query = mysqli_query($con,"SELECT target FROM emailtbl");
$query_display = mysqli_query($con,"SELECT * FROM emailtbl");
while($row=mysqli_fetch_array($query))
{ echo "<option class=highlight value='". $row['target']."'>".$row['target']
.'</option>';}
echo '</select>';
?>
<input type="submit" name="submit" value="Submit"/>
</form>
= ' '= $_POST[="SELECT target, username, password, emailused, lastused, purpose, saved FROM emailtbl WHERE target = '$name'"= mysqli_query($con,$fetch);

while($data=mysqli_fetch_row($result))

}

Things look wrong starting at mysqli_stmt_bind_param to me - you're binding the $sql variable to the parameter, and not setting the ID value to use before calling execute on the prepared statement.
Take a look at the examples on the manual page, it should become clearer: http://uk.php.net/manual/en/mysqli-stmt.bind-param.php[^]

This seemed to be a better approach but I can't get it to work either. I'm trying to change from MYSQL but having trouble ?
connect_error) die (
'Connect Error (' . $db->connect_errno . ') ' . $db->connect_error
);
if (!empty($_POST['update_lastused']))
{
$stmt = $db->prepare('
UPDATE emailtbl
SET lastused = NOW()
WHERE id = ?
');
$stmt->bindParam('s', $_POST['id']);
if ($stmt->execute())
{
echo "";echo "Last access is:";
echo $lastused;echo "";
}
else {echo 'There was a problem setting lastused" - ', $stmt->error;}
}
?>

You should use Google for such kind of generic questions. You will get many such samples.

I have 30 years development experience. I do C# and WPF. I have some experience with MVC 4 Web API's. It's time for me to transition into web development.
I want to learn ASP.Net MVC. I did get into MVC 4 a while back never went too far.
The question... What is the .Net stack I need to learn? I don't really know what technologies I need.
Thanks

I would suggest to start with a basic .net book. Then dive deeper into code according to your need.

A basic .Net book??
Why? I have 30 years development experience, including 12 years doing C# & WPF.
.Net isn't an issue for me

Oh!! my mistake. I didn't notice that.
Get an Asp.Net MVC book and read abt its architecture and patterns. At your experience, i think, you can finish it as a story in few hours. 
I think, this should be sufficient for you to start with.
Moreover, asp.net/mvc website is also a good place to start.

I am pleased to see that you have 30 years of experience and you want to learn MVC.
I was starting MVC before 8 months ago and it was wonderful experience to learn .
My learning path was
1) I started with some small samples on http://www.asp.net/mvc[^] on almost all topics.
2) JavaScript
3) JQUERY
4) AJAX ($.Ajax)widly used (http://api.jquery.com/jquery.ajax/[^])
5) JSON
6) Entity Framework

One thing that has not been mentioned much here is that when you are working with WebAPI(2), you also need to keep in mind the consumption of your services.
When considering the modern SPA or service-to-service approach, I find it helps to tack it to an n-tier model for the purposes of figuring out what my needs at any given point in the stack are. The WebAPI can serve 2 purposes, data layer only or data mixed with business. The consumer can be considered in the same way, if it's an SPA then the consumer is either UI only or UI-business.
If you're trying to develop a framework, I'd flesh out the approach that I wanted to take and find(or write) a JS framework that best serves my approach. I like using WebAPI2 as a Data source, so I've been working with Angular to handle business and presentation logic. I have other apps that I base out of MVC instead, and just use jQuery/vanilla JavaScript with those.
I do think that the JavaScript environment is one that needs to be considered carefully when moving into the modern web app landscape.

It sounds like you already have a good base to work if you have previous experience using C#, MVC, WebAPI and WPF.
If you want to get further into web development then look into ASP.NET with / without MVC. Start with the basics and then progress into more complex data-driven / ecommerce systems.

I built a web site for a company. A few months ago, the company owners split, and one of them started up a new company (new domain and everything), and I used the site code from the original web site, but changed some logos, and changed (what I thought was) all instances of the old name to the new name. We left the original site up with a redirect to the new site.
Now, when we search google for the company new name, it still finds the old site.
The old company name is "South Texas Performance".
The new company name is "Two Ten Performance".
When I google "two ten performance", it finds "south texas performance".
Can someone please tell me how to fix this?

Seems OK to me - a search for "Two Ten Performance" is finding the right site, and a search for "South Texas Performance" is listing both, with the old site first.
Does the page really need 184 Javascript includes though? (Yes, really - document.scripts.length == 184)

Google will report it's findings based on the data it holds from the last time it crawled your web site. Google (or indeed any search engine) doesn't work in real time but based upon data it holds from crawling web sites. As web sites get updated and change, so the information that Google holds will likewise get out of date, until the next time it crawls your site.

In many situations developers need to complete web projects in short time or deadline and requirements are many.
Clients don't like compromising quality.
How to handle such situation?
Thanks
