Compare Values From Data Source To String
Jun 24, 2010
I'm just stumped on what to do with this code, I'm just trying to implement a 'no duplicates' catch on my insert customer form, but it just slips through my if statement to the else everytime. This is the source. Also I tried a .Equals with the same results :(
Protected Sub srcAllClients_Inserting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceCommandEventArgs) Handles srcAllClients.Inserting
'Establish Variables
Dim emailAddress As String
Dim srcUsers As SqlDataSource = New SqlDataSource()
srcUsers.ConnectionString = ConfigurationManager.ConnectionStrings("ISSD21ConnectionString").ConnectionString
Dim view As DataView
view = DirectCast(srcUsers.Select(DataSourceSelectArguments.Empty), DataView)
srcUsers.SelectCommand = "SELECT EmailAddress FROM ISSDClients"
srcUsers.DataSourceMode = SqlDataSourceMode.DataReader
Dim reader As IDataReader
reader = DirectCast(srcUsers.Select(DataSourceSelectArguments.Empty), IDataReader)
emailAddress = FormView1.FindControl("txtEmail").ToString
While reader.Read()
If reader("EmailAddress") = (emailAddress) Then
lblError.Text = "Your Email is NOT Unique!"
'this is where we cancel the update and return an error
Else
lblError.Text = "Your Email is Unique!"
'nothing needs to happen, maybe just tell them that it went through
End If
End While
reader.Close()
End Sub

I am using SQL data source to display existing records from database as well as adding new records to the database.But in VWD 2008 we can insert only those values which have been inserted into the text box,if I try to change the values or text the Insert option gets disabled.I want to allow user to add only specific field values,for the rest I have created session variables and want to use values from these session variables to be inserted into database.

I have a textbox for a child's name. The user may enter just the first name, first name + middle name, or first name + middle name + last name for their child. How do I separate this string of texts appart so that I can compare it to the parent's last name textbox before inserting into the database? For example, if one part of the three parts in a child's name matches the parent's last name textbox then delete this part out of the child's full name before inserting into the database.

I have a string value from a user input box. I have to figure out if last char is a enter key (line feed).
Thats the code. Here I am checking if last char has a whitespace. Now I also have to check if last char is enter key (carriage return or line feed). How can i do this?
var txt = $get("<%= txtUserText.ClientID %>");
if (txt.value.substring(txt.value.length -1) !== ' ' || <checkifLastCharIsEnterKey>)
//my code to take action
**I don't think i need a keypress or keyup event because this above piece of code is not invoked at the time of user input.

All of the examples I can find show the compare validator being used to see if two values are the same. Validation is succesfull if these values are the same, such as password confirmation.I want validation to succeed if values are not the same. I want to use this to be sure that someone doesn't enter the same value for two phone number fields. I want the two values to be different. Can the compare validator be used for this? I wasn't able to find any properties or examples that used it in this way. If not, how should this be done?
