View 1 RepliesC# - Verify That Email Domain Exists?
Jun 14, 2010Does anyone check the domain of an email address as part of their verification steps? eg. Confirm that gmail.com exists if the user specified blah@gmail.com as their address.
I should note that in my webapp an existing user can forward invites to their friends. I have no need to verify those invites at all. Rather, I just want to warn my user if a typo etc. may be sending an invite to the wrong person. Is this even worthwhile to do?

Dec 7, 2010What is the way to :
1) Check if a file exists on an FTP site.

View 1 RepliesForms Data Controls :: Check If A GridView Exists?
Dec 9, 2010I have a page with a simple textbox, when an OrderNo is entered in te textbox the page is populated with 2 or 3 gridviews depending if the order has items reserved or on back order.
GridView1 has data about the order, like status, payment details.
GridView2 has data about orderitems, each row displays an item from the order with stock and order quantities
GridView3 has data about backorders, each row displays an item from the order with quantity reserved and quantity on back order. As is no data for GridView3 if order is not on backorder I thought that I can enclose my code inside an if block
if GridView3 isnot nothing then
'getting some data from the cells in GridView3
endif
but the code still executes.
Web Forms :: Check If Child Node Exists On Treeview?
Jan 24, 2011I have some data that I am putting on a treeview and have a checkbox on the page to decide if the user wants to order the nodes by date or type.
To do this I need to check if the code has already added a child node so when grouping by the type I don't put it in lots of times.
Lets say I have Type 1 and Type 2 and each have 3 items that would fall under these I want to achieve:
Type 1
Item 1
Item 2
Item 3
Type 2
Item 1
Item 2
Item 3
Instead of:
Type 1
Item 1
Type 1
Item 2
etc etc etc
I tried using the node.Contains function but it doesn't seem to exist (I am using c#).

SQL Server :: How To Check If A Record Exists In VWD?
Dec 21, 2010I am very new to this and have watched a lot of the videos. While trying out VWD2010 and SQL2008 Express, I come across many things, I just don't know how to do. Here is the latest:
I have a Table
UserId - Int - AutoIncrement
FirstName - Var(10)
LastName - Var(10)
I also have an ASP web page that allow the user to enter a first name and last name. It also has a button to submit. What I would like to do is have a Select statement check to see if the name already exists, then send a comment back to the user via a label. If it doesn't exist, then I would like to Insert the info and then again inform the user via label.
SelectCommand="SELECT COUNT (UserId) FROM Users WHERE ((FirstName=@FirstName) and (LastName=@LastName))"
InsertCommand="INSERT INTO User(LastName, FirstName) VALUES (@FirstName, @LastName)"
<InsertParameters>
<asp:ControlParameter ControlID="tbFirstName" Name="FirstName"
PropertyName="Text" Type="String" />
<asp:ControlParameter ControlID="tbLastName" Name="LastName"
PropertyName="Text" Type="String" />
</InsertParameters>
<SelectParameters>
<asp:ControlParameter ControlID="tbFirstName" Name="FirstName"
PropertyName="Text" Type="String" />
<asp:ControlParameter ControlID="tbLastName" Name="LastName"
PropertyName="Text" Type="String" />
</SelectParameters>
On the code behind, I get lost. (Obviously this doesn't work, but I don't know how to go about getting a results back. Protected Sub bSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles bSubmit.Click
SqlDataSource1.Select(DataSourceSelectArguments.Empty)
