I have a stored procedure that updates a record.
I need to add code so that it only runs IF the parameter passed has a value

The parameter is:  request.querystring("marriageidspouse")

If the parameter does existing run the SP code, something like:

IF request.querystring("marriageidspouse") <> NULL THEN 

MY CODE

END IF

Both websites are on the same network, one is an intranet, one is an internet. We want to display some content (XML) from the Intranet site on the Internet site. Can the internet site serve content from the Intranet site if it's given permissions. Any suggestions?

Hi,

What is the correct/accepted terminology for a small portion of a screen that does not necessarily contain a data field?
Here's an example from a public website (not from my client work).

1. Click 'Races'.
2. You will see the following: ___________________.  (segment? display? snippet?)
 Example3. To filter by distance...
etc.

How would you fill in the blank in step 2?
Thanks.

end if

I work for a organization with a large website. I have been asked to provide the following stats from 2016 about the website:

  • total number of web pages on our website
  • total number of page linked to a newsletter

Regarding bullet number two: A friend suggested that I use Campaigns to track pages being linked to newsletters, which I assume would mean creating a different campaign for every newsletter link. I can do that going forward in 2018, but that doesn't help me find the stats for 2016.


Can I retrieve the 2016 stats for both bullets from GA and how would I do so? If it can not be retrieved from GA, please offer suggestions on how I may find this information.

We have recently migrated a .NET web application which uses web forms to be hosted on Azure.  We use session variables to keep some objects in memory after we query from the database to avoid multiple trips to the database: 

string companyName = Session["Company"];

Open in new window


It was brought to our attention that azure doesn't handle session variables well and that another method should be used.  Either through table, sql azure, or azure cache.  We were thinking of using the latter, the azure redis cache.  Is this an issue we should address right away as we are about to release to production?  Also, if we cannot address it right away, how unreliable it will be to use the current session state management?  If this is an issue now that we need to address is using the redis cache the best route to go?  This is a moderately sized app with no more than 200 users.

When I email a list of results via email we currently only have the HTML which is not very nice formatting.
When I display it as a webpage we use bootstrap so the formatting looks nice.

Is there a way to send the HTML table via email and make it look nice?  like the one we have online using bootstrap classes?

Alternatively do you know of any nice HTML5 template I can use to email tables with repeated regions?  (Many records)
I am trying to improve the look/feel of the email.

I have an ASP page that has about 20 recordsets. Each recordset returns a maximum of 10 records, some only return one.
Would the ASP run faster if the code to return the records is in the ASP page or would it be faster if I create stored procedures that then the ASP would call to create the recordsets and return the records?

I am using ASP classic and MS SQL 2012 R2

Hi there,

So in my project I have a *ngFor loop and then in the child element I have a *ngSwitchCase that will produce an error.

The error says: 'Can't bind to '*ngSwitchCase' since it isn't a known property of 'div'.'

Here are screenshots:

I received the following email today regarding one of my registered websites:

As part of the rules of domain ownership, ICANN (the international governing organization of domain domains) requires that your contact information be publicly accessible. Therefore, your name, address, email address and phone number are made available to anyone who performs a whois search for the domain name.

We understand that making this information publicly available is not the best solution for many customers, but it is a requirement for domain ownership. In addition, using false contact information violates domain registration agreements and could lead to loss of domain ownership.  But there is now an alternative:

---------------------------------------------------------------
Private Whois Service is now available to protect your privacy!

In order to help protect our customer's privacy we offer a Private Whois service which will remove your private information from the whois database. This service will display proxy information for the name, address, phone number and use an alias email address. Any emails sent to the proxy email will be forwarded to your actual domain contact email address.

The Private Whois service is $5 per year and can be activated by visiting your Control Panel Domain manager at:

I'm a bit confused on how they, or anyone else for that matter, can offer this service, as I …

Hi,

If im looking to setup a web spider that searches online for mentions of a firm name and alerts whenever mentioned. I know i can setup one that searches specific URLs i give it, but im looking for more of an industry and USA news search and maybe i can add a few that sites. Are there free web spiders/crawlers that provide this service?  I searched online and found YaCy, not sure if anyone has used it or if it's safe to download. Also found paid services like 80leggs and connotate, but it seems like i have to provide the sites and it wont do a general search. Any product out there that does this?

Let me first say this is high level and I may be missing certain information.

Working a back end system that will contain REST Services that will be used to create requests and retrieve list information. The data being passed back and forth will be JSON.

The web application I want to build should be a single page application. Some of the key features needed:
1. Single Page Application - Store user data (Preferences)
2. Single site should work with Browser and Mobile Devices (Mobile Web App)
3. Everything one click away (AS much as possible)
4. List Display (Datagrid)
5. Request forms via Modal Window

At a high level what language(s) would you use to accomplish this?

Thank you in advance.

I essentially have 2 forms on one page. Each has some input controls and a button. I want to validate the controls relative to the button, but when using basic bootstrap validation techniques, both buttons validate the entire page.

How do I break up the forms and only validate the controls relative to the 2 buttons?

For example...

 <div class="col-lg-12">
    <h2><u>Daily Schedule</u></h2>
    

    <div class="col-md-3">
    <label for="heard2">Enabled?</label>
    <div class="form-group">
    <asp:DropDownList ID="ddlDaily" runat="server" class="form-control"></asp:DropDownList>
    </div>
    </div>
    
                    <div class='col-md-3'>
                     <label for="heard">Start Date/Time <i>(will repeat daily)</i></label>
                    <div class="form-group">
                        <div class='input-group date' id='myDatepicker'>
                            <asp:TextBox ID="tbDDT" runat="server" class="form-control"></asp:TextBox>
                            <span class="input-group-addon">
                               <span class="glyphicon glyphicon-calendar"></span>
                            </span>
                        </div>
                    </div>
                    </div>
   
    
    </div>
    <div class="col-md-3">&nbsp;&nbsp;&nbsp;<asp:Button ID="Button1" runat="server" Text="Submit" OnClick="Button1_Click" class="btn btn-primary" /><br /><br /><br /></div>

Open in new window


How would I only validate the fields above when clicking the button above, ignoring anything else that might be on this page?

Without even knowing it, most of us are using web applications on a daily basis. Gmail and Yahoo email, Twitter, Facebook, and eBay are used by most of us daily—and they are web applications. We often confuse these web applications tools for websites.  So, what is the difference?

The problem i am having in alignment of input and select fields. html and css code is attached. I am having hard time for resolving this as i am beginner in css learning.

Select fields for choosing time       from    [hour] [minutes]              to     [hour][minutes]  should be easily understood by user. right now it is not so.
Page is divided into two parts  - > left and right side.  left side's width is 60% and right side's is 40 %.

Form is in the left side. (which is to be consider)

Hi,

I am travelling in main land china and naturally sites like google and YouTube etc are blocked.

I am thinking about getting one of the iOS vpn apps.

My concern is it monitoring my internet data in regards to passwords I type the mail app etc.

What I am thinking is if those programs do the encryption themselves I will be safe and this can't be attacked. SSL sites will be safe.

Are my assumptions correct? Are there any risks at all?

Thanks
